Connecting a telephone socket: options, schemes, features. Unpinning the telephone cable “4 lived in the sequence of pressing the telephone cable

RJ11 is a physical interface that is used for connecting telephone cables. Vikorist in old telephone networks with one line all over the world.

RJ-11 is used for pressing telephone cables. Suitable for a standard analog telephone that plugs into a standard telephone jack. Color marking is not of particular importance (a classic telephone only has two middle contacts), but it is better to adhere to the accepted standards so that you never think that you will have to drag one end of the cable. The pinned contacts of the RJ-11 telephone jack are located lower.

Layout diagram and crimping RJ-11 connector for telephone cable

The signal must come to the two central contacts of the connector. To install European RJ-11 plugs and telephone-handset plugs, you need to press a special pressing tool, but if you need to squeeze 1-2 plugs, then the contact plates can be pressed flat into the and twist. For installation, it is not necessary to clean another ball of insulation; the technology transfers the penetration of insulation to the contact pads of the plug.

The telephone line is connected to the red and green wires at the socket - this is standard (for the RJ-11 connector this corresponds to the middle, 2 and 3 contacts). There is a lot of equipment for the German campaign and the formation of the German Empire. The red (yellow) color indicates a minus in the telephone line, and the green (black) color indicates a plus. In principle, the polarity of switching on is not important in most cases, but the actions of all sorts of telephone devices are adjusted, as they say, so that “everything is correct.” You can determine the polarity of the telephone line by connecting the original Chinese tester (when the voltage is turned on, it will show a negative voltage value), and if it is not near your hand, tie the bare end of the cable into a freshly cut potato, the color will change at the “plus” end. True to the polarity of respect, no one, say, does not die.

Be careful when connecting to the telephone line - at the moment of “quiet” the voltage in it is close to 60 Volts, and at the moment of ringing there appears a changeable voltage of about 100-120 Volts - this is already quite enough!

Sometimes it may be that you don’t have a crimper (pressing device) at hand, and it is necessary to crimp the connector. In this article, we will look at how to quickly navigate these reserves, vikoryst and primary tools.

We need this:

• thin twist with a flat tip
• connector
• wire twisted pair
• knives
• goal

How to make a connector with your own hands?

1. Let’s say we don’t have any new connectors, and we already have a lot of vikorstans.
2. After the head is pulled through all the copper clamps that are pressed, from the connector.
3. The connector is connected to the hole.
4. Let's carefully turn Clemie on the spot.

Ready connector.

Connector pressing technology:

RJ-45 (computer connections):

Using scissors, we cut the tip of the pair's twists.

Using a knife, remove the plastic braiding by 3-4 cm and develop colored wires.

We form them in a line in this order, from left to right.

We squeeze the cord with our fingers, protrude 1.2 cm from the braiding, and cut the dove with scissors.

Carefully insert the dart into the connector, following the sequence, pushing it with the latch down.

Press the connector to a hard surface so as not to damage the retainer.

We squeeze a twist through the terminals, then squeeze the wire.

RJ-11 (telephone connector):

The telephone line is cut.

We peel off the braiding by 1 cm.

Virus of wiring (red-green)

Plugs into RJ-11 connector. Pin3 – red Pin4 – green.

We squeeze the adhesive with a twist, then conduct it.

The connection is unreliable in such a way, otherwise it will help to get out of the situation.

Among all maintenance and repair procedures for communication systems, correct crimping of the telephone cable is of great importance. In order to understand this operation, it is necessary to know what types of telephone cables there are.

Standard telephone cables

Whether the telephone wire or cable is connected with special wires designed for laying landline subscriber lines of the open or closed type. Their basis is the strumoprovodnye lived with, the crossbars of which become less than a few inches of a millimeter. They lived in special individual isolation. For skin isolated steam there is a different color. I guess all the pairs are twisted around the cables.

The skin is prepared with a virus that can be connected immediately. This procedure is very simple, just remember the simple rules and sequence of all operations.

How to crimp and connect a telephone cable

For practical connection you need:

1. Telephone wire,
2. Telephone socket
3. Standard compression device.

First of all, we cut a piece of cable, after which we may move five meters, otherwise we may need to boost the signal. Using knives, loosened in a pressing tool, carefully remove the top insulation of the cable on the riser approximately 7-8 mm. If necessary, the conductors can be carefully trimmed.

The prepared conductors are placed in the socket until the end. It is located in the housing of the socket at a depth of approximately five millimeters. The linear layout allows you to easily move the conductors around the connector. Their versatility is also not foldable, due to the transparent plastic housing of the connector.

In order to crimp a telephone cable straight from the middle, you need a special tool designed to work with different connectors.

Under pressure, the knives are pressed into the middle of the body. The shell of the conductors is cut and contact is created. At the connector, the cable is securely fixed with a flat bar. The finished socket together with the telephone wire is inserted into the socket, after which the connection is installed.

Thus, crimping and connecting a telephone cable is a cumbersome operation. Due to the presence of new skills and a necessary tool, the connection is made using a number of strands.

Telephone roses

Mobile communications services have a lot to do with the collaboration between people who have made them handy and accessible. A modern person does not need to rush around searching for a telephone booth or a token to stop the ability to ring. However, regardless of the undeniable advantages of mobile communication, landline phones and dart connections, as before, produce a great drink, depriving them of the reliable method of acid connection. In addition, the devices themselves have become much more user-friendly and functional. For this type of communication it is necessary to have telephone sockets available. These roses have their own characteristics and differences in installation methods and they must be observed correctly when connected. It is clear how to connect the telephone socket to the telephone cable, look at the diagrams and instructions.

Design of a telephone socket, cable connection

Behind its interior, there are sockets for connecting telephones and devices for transmitting signals, there are few electrical outlets and power lines. The smell arises not only structurally, but also due to the installation method. To understand all the subtle connections of a line connection, it is necessary to understand the features of the device and the operating principle of switching devices. Also read the article: → "".

The telephone line constantly changes depending on the handset position (on or off), the connection (connection or disconnection). If the device is not connected to the limit, a constant current of 40-60 V flows along the line. A similar situation arises if the phone is connected, but the handset is hung up. At the moment of the bell, the voltage rises to 120 V, changing when it changes. Removing the tube reduces the value from 6 to 12 Volts.

All these processes are carried out on a flat arrow, which can be made from two veins. It could be aligned with the PPV wire, which is used for electrical wiring, but the retin lived on the flooring only a little, which allows for stagnation only for important applications: telephone lines, as well as automation circuits (security or fire alarm tsії).

There are several types of sockets for connecting phones:

• RTShK-4 – can only be used for older devices;
• RJ-11 - current version, "Euro" rank;
• R.J.-12 – slang name for roseR.J.-25, as the tables have become so wide-ranging that, for the sake of clarity, this information is accessed more often than today. In reality, there are no such sockets, so we understand the term R.J.-12, mother's trace on the carR.J.-25 .

The RJ-11 telephone jack is located near the port for the line plug. The external one is similar to a computer socket, but with more attention to detail, you can note that their sockets vary in width (the computer version is wider).

The most extensive options for installing devices:

• invoices, external stench;
• outside, internal stench.

There are also viruses that are generated, but they are prepared in the form of blocks that are usually connected to several types of switching devices - electrical, TV, computer and telephone. Also read the article: → "".

Different types of telephone sockets may be stuck in different minds

It is also a design that combines RTShK-4 and RJ-11, which at the first stage was able to supply power to imported telephone sets from European sockets in the country's territories. Nina has become morally outdated, but wants to continue to successfully become a victor.

An option for a device that connects RTShK-4 and RJ-11, suitable for different plugs

Today's telephone calls can most often be two-vehicle or two-vehicle. In this case, the isolation of the veins is characterized by a more color-coded discoloration. Wires with a number of wires are usually used for office telephone exchanges, as well as when two devices are connected in parallel according to the secretary-director principle. It's time to get stuck with RJ-12 connectors.

Connecting a telephone socket

Connecting RJ-11 and RJ-12 sockets is completely the same, depending on the number of conductors that are connected. The most commonly used are double-darts, which does not cause any problems with commutation. The situation is different with many living viruses, the connection of which must be carried out according to the color scheme.

Before starting the robot, the socket is disassembled (the top panel is removed). The outer shell of the phone will be removed as needed. Depending on the type of contact, the conductors are cleaned or stripped of their insulation. Further entries are carried out according to the instructions.

Switching with double wire (RJ-11)

Pokrokov's instructions will help you connect the switch:

1. On the inner part of the device there are loose adhesives or contacts. If bolt contacts are evident, it is necessary to determine the color of conductors that are connected to them. According to international standards, the red conductor is negative, and the green conductor is positive. The ends of the supplied telephone wire are connected to them

1. Since the structure of the device transmits terminals, the ends do not need to be cleaned. The plugs are inserted into the base of the clamp and pressed until it stops with a thin flat twist. Miniature knives, transferred to skin contact, cut through the insulation and ensure reliable contact. In this case, engage the middle terminals 2 and 3

1. Attach the device to the wall and check its usefulness
2. Close the front panel. Installation completed.

Connecting the socket with a 4-wire wire (RJ-12)

Before installation the following will be brown for the following reasons:

This switching method is standard and will ensure ease of maintenance and repair of telephone lines.

Connectors for connecting phones to sockets

Like telephone sockets, connectors to them can be connected using a single-core (RJ-11 system) or multi-core cable (RJ-12 system). Connecting the connector with a wire made from 2 cores is subject to the following procedure:

1. The outer dry casing is visible, leaving the thin ends of the wedge 10-12 mm.
2. Without stripping the insulating ball, the conductors are inserted into the connector body in the middle position 2,3. The first and fourth of the klems will be deprived of their freedom
3. The contacts are crimped using a special tool or screws with a thin base.

As soon as the old structure (lokshina) is recovered, its veins are cleaned and placed in a shell against the rotation of the steam, after which the process proceeds. When a 4-wire cable is connected, the middle contacts 2.3 have red and green wires (or blue or white-blue), and 1.4 have black and yellow wires (or orange and white-orange). After this, crimping is carried out.

Color diagram of a 4-wire cable in a telephone line connector

Pressing with the help of additional twisting is done with a hand press until it stops on the skin from the contacts of the connector. Once the insulating ball of the conductor is tested, the connection will be secure.

Inspection of household telephone sockets

When choosing a plug-in device for connecting a landline telephone, it is important to give preference to brands that have a positive reputation in the electronic technology market, verified over time. Among such brands are Turkish companies Lezard, VIKO, as well as manufacturers from France - Schneider Electric, Legrand Valena. To compare the average prices from online stores for the products of the indicated manufacturers, please refer to the table:

Rules that are allowed when choosing and installing telephone sockets

The main reason for all pardons is lightness and disrespect. Having become familiar with these recommendations, you can solve problems and problems with the installation of switching devices.

Practical recommendation: If the operator is not new to working with electronic devices, do not use a power tool to install the telephone socket. It is necessary to contact the fakhivtsi for help to ensure that the socket is installed correctly and reliably.

Pardon 1. After opening the package, the instructions that are provided are removed from the connection diagram indicated on the body of the device. The circuit may be different or may be difficult to install during installation.

Pardon 2. Carry out installation without electrical gloves. As indicated, the voltage at the boundary can rise to 120 Volts. We pay attention to those who do not have “safe voltage” and are threatened with unacceptable consequences. It is necessary to install robots with advanced safety equipment.

Pardon 3. Buyers can get away with it and buy devices from an unknown company at a low price. This is a savings: the product may appear unclear and there are no guarantees, so it will be impossible to exchange it or return the money. Every brand offers a warranty on its products, which guarantees its quality and reliability.

Pardon 4. During installation, the conductors shorted out among themselves and the telephone line was disconnected. There is no need to panic and call a repair team from the telephone company. The line is automatically dialed through the central telephone exchange. This connection is maintained for a few minutes, after which the robot is updated.

Pardon 5. Vikoristannya drotu, filmed in an old building or in a heavenly location. This wire may be damaged by insulation or a damaged core. This will definitely be identified as a link. It is better to add a new cable that meets current standards to ensure trouble-free connections.

Finally, I would like to note that, regardless of the expansion of mobile phones, landline devices continue to be widely abused due to the independence of territorial coverage and various roamings. In addition, a wired connection allows for a clearer connection, but sometimes lacks the only available means of notification.

In addition, how competently the pressing of the telephone cable will be done. there is a lot of liquid in it. To connect telephone cables to devices, mini-PBXs in offices, administrative buildings, and apartments, use RJ-11 connectors, which are similar to standard R-11/12 telephone sockets. In this article we will look at how to compress a telephone cable to an additional connector.

What tools and materials are needed for pressing?

The first step is to press the telephone cable, it is necessary to step up:

Telephone cable (link) - KSPV 2x0.4 (standard telephone equipment) and KSPV 4x0.4 (digital programmed telephone equipment). Recording tool (everyday and stationery tool). Connector RJ-11/12/25.

A special crimping tool is a crimper (on some models there is also a bottom that allows you to cut the cable).

How is Viconati squeezed for additional crimper?

Crimping a telephone cable most often involves using a special tool - a crimper. Proceed in the following order:

Take the outer shell from the end of the telephone dart (by 0.5-1 cm). They themselves cannot be cleaned, so the connector blades need to be cut through. The layout (Fig. 2) for the KSPV 2x0.4 cable has nothing foldable. The signal must fall on the two middle contacts of the connector. The KSPV 4x0.4 connection can be extended to a direct layout (skin contact on one core).

Insert it all the way into the connector. It is important that from the front side they go to the end of the channels. Insert the connector into the crimper and squeeze it.

Everything is squeezed onto a Wiconano telephone cable. There is no need to remove the crimps on the cable and carefully look at the “knives” of the connector for damage to the contact. If the contact here is bad, you need to cut the cable, install a new connector and press it again.

If the crimp of the telephone cable “2 wires” or “4 wires” is crimped correctly, you will hear a beep in the telephone receiver.

Nuance vikonannya pressing without crimper

Crimping the telephone cable on 2 or 4 wires can be done without a special tool. It won't matter to you. Well, let’s look at how to crimp a telephone cable without a crimper.

To properly crimp a telephone cable “2 wires” or “4 wires” without a tool, press the following:

Maintain the required strength of the cable and clean the outer sheathing. Insert them into a connector (2-wire - for two middle contacts, 4-wire - for skin contacts with one wire). It's your fault to die. Take a flat screw and, with help, press the contacts in successively.

Press with a twist into the clamp located on the connector. The cable is not easily accessible.

When crimping a telephone cable in this manner, be very careful and respectful. This method will always ensure high hardness of the pressing. Before that, the high riser will damage the cable.

Know how to squeeze a telephone cable “4 wires” or how to squeeze a telephone cable “2 wires”, you will easily run into these problems. You can work either with or without the help of a crime guard. The whole process will take a lot of time. First of all, take to heart everything that is written above. Only then will you be blessed with a clear telephone call.

The company "Kable.RF" is one of the leaders in the sale of cable products and has its own warehouses, distributed in almost all regions of the Russian Federation. By consulting with the company's representatives, you can obtain the brand of telephone cable you require at competitive prices.

RJ11 is a physical interface that is used for connecting telephone cables. Vikorist in old telephone networks with one line all over the world.

RJ-11 is used for pressing telephone cables. Suitable for a standard analog telephone that plugs into a standard telephone jack. Color marking is not of particular importance (a classic telephone only has two middle contacts), but it is better to adhere to the accepted standards so that you never think that you will have to drag one end of the cable. The pinned contacts of the RJ-11 telephone jack are located lower.

Layout diagram and crimping RJ-11 connector for telephone cable

The signal must come to the two central contacts of the connector. To install European RJ-11 plugs and telephone-handset plugs, you need to press a special pressing tool, but if you need to squeeze 1-2 plugs, then the contact plates can be pressed flat into the and twist. For installation, it is not necessary to clean another ball of insulation; the technology transfers the penetration of insulation to the contact pads of the plug.

The telephone line is connected to the red and green wires at the socket - this is standard (for the RJ-11 connector this corresponds to the middle, 2 and 3 contacts). There is a lot of equipment for the German campaign and the formation of the German Empire. The red (yellow) color indicates a minus in the telephone line, and the green (black) color indicates a plus. In principle, the polarity of switching on is not important in most cases, but the actions of the most important telephone devices are adjusted, as they say, so that “everything goes right.” You can determine the polarity of the telephone line by connecting an original Chinese tester (when the voltage is turned on, it will show a negative voltage value), and if it is not at hand, tie the bare ends of the cable to a fresh I add potato, and the color will change at the “plus” end. True to the polarity of respect, no one, say, does not die.

Be careful when connecting to the telephone line - at the moment of “quiet” the voltage in it is close to 60 Volts, and at the moment of ringing there appears a changeable voltage of about 100-120 Volts - this is already quite appropriate!

What is the correct wiring diagram for a telephone cable?

I think that someone who may or may not have a landline telephone has been forced to squeeze out the telephone cable. As people are familiar with this right, there is nothing wrong. If you have never encountered such a place before, you may simply find yourself dead. Aja really doesn’t want to call the master for the sake of such rubbish. Well, don’t boast, the mischief is entirely real.

It is very difficult to work with such thin veins, especially since there is no suitable instrument, and it is easy to tear. The skin vein is placed in a singing color insulation. The wiring must be connected to the contact, otherwise you need to know the connection diagram. There are two types of standards, called T568A and T568B. Russia has adopted another one - T568B. If I want to make special contraindications to other standards, I don’t consider them, because that’s what’s needed. However, choose only one scheme and apply it to each section of the cable line.

• telephone wire,
• pressing device (anything can be rented),
• RJ-45 connector

Cut the casing with a utility knife or a utility knife, remove it and the inner veins will appear in front of you, straighten out the darts and grind them as they stink. Verify them along the same line of agreement and, if they are from different dates, submit an application. Insert the dart into the connector until it stops, stitch so that the skin vein stands at its groove. You squeeze and enjoy the wicked work.

You can also try squeezing the cable using additional twists, otherwise there will be no problem, you can find tutorials on YouTube.

the system chose this answer as the best

T568A and T568B are tables that describe the connection of conductors to a twisted-pair cable (dart). These tables are up to TIA/EIA-568 standards; TIA/EIA-568-B. These standards are issued by the US Telecommunications Industry Association. TIA/EIA-568-In effect since 2001, the replacement of TIA/EIA-568-A. These standards determine the need for cable systems to be used when organizing Ethernet connections. "Registered Jack" RJ - standardizes the physical edge interface, which includes a description of the design of both parts of the connector ("plugs" and "sockets") and their switching circuits. This interface is created for connecting telecommunication equipment. The RJ45 “plug” (“tato”, whatever you want), as described by you, has no connection with telephone lines. To connect telephones, the following standardized interfaces are used: RJ11 – for connecting “wired”; RJ12, RJ25 – for connecting “multi-wired”; RJ14 – for connecting “four-wire” telephones.

If you can’t respond to the question, don’t confirm, but indicate those that you can’t indicate the middle manifestation, at least, incorrectly. - More fate than that

The telephone cable can be of 3 types, which can be made up of 2, 4 or 6 cores. Whatever you need, you can be given a telephone set. Observe the socket in the device and check the number of possible wires at the socket. Zazvichay tse 4, ale mozhe buti 6 (for the new ones) or 2 (for the old ones). Carefully take the required jack (RJ25 – 6 wires, RJ14 – 4 wires and RJ11 – 2 wires) and work on the wiring according to your color scheme.

How to crimp a telephone cable?

There is no particular difference in crimping the cable for the telephone, since this cable is connected to the telephone outlet. There are only 2 middle contacts there. The polarity of the role connection does not matter.

To crimp, you need to strip the outer insulation of the cable. Insert the cable into the socket, making sure to place the cable in the center of the socket. Let's squeeze it further.

If it is required exactly according to the standard, then we squeeze it together with the table

Marina Vologda

more than a month ago

Let's take a look at how to squeeze the torsion cable step by step:

1. Break the isolation and unravel the bets that divide them over colors

2. Align and squeeze the conductors. Trim them so that they are one cm long.

3. We attach the fork in such a way that the conductors reach the end

4.Check that the bookmarks behind the colors are correct and that everything is correct, then place the fork in the press.

And the video axis shows how to properly crimp a telephone cable:

First of all, I want to say right away that for comfortable work related to pressing, it is important to use a tool of this type:

And to strip the cable, use the following:

If there is nothing more than what is described, then you can quickly cut it with a knife and hammer

The first thing you need is a connector and cable

Squeeze of the Old Bet

To connect this pair (Internet cable) you need an RJ-45 connector

If you are using a cable with 8 cores. 8 cores are vicorized to obtain a speed of 1 gigabit along the edge. Then the layout is like this:

1) White orange 2) Orange 3) White green 4) Blue 5) White blue 6) Green 7) White brown

8) Brown

Axis miraculously demonstrates a picture on the Internet know

I also want to mean that the split is straight. And he is victorious in the most important situations. And there is also cross-pinning. Vaughn was involved in connecting two PCs. This won’t happen today. These current routers and switches can be used to turn over the straight cable. I'll tell you about all sorts of bad things. Raptom who needs it

1) White green 2) Green 3) White orange 4) Blue 5) White blue 6) Orange 7) White brown

8) Brown

If you are using a cable with 4 cores. Then the layout is like this:

Left to the right.

1) White orange 2) Orange 3) White green 4) Empty 5) Empty 6) Green 7) Empty

In this layout you can see whether there are pairs of colors, the smuts lived in different connectors and were in their places.

Crimping a telephone cable to a cable

To connect the telephone cable, you need an RJ-11 or RJ-12 connector

For the booth, consider adding RJ-11 with two cores. You can have a couple there. Golovne, so that the connectors had stinks in the right ports.

1) White-orange 2) Orange

For an office with IP phones or digital phones, use RJ-12 with 4 wires. You can also have a couple there.

1) White orange 2) Orange 3) White green

4) Zeleny

Remember how the numbers change. When the socket is connected, the stinks will help us find our way

Now let's look at the sockets

How to connect an outlet to the router

We have already figured out how to crimp the connector. Now you need to connect the socket on the other side of the cable

It needs to be pinned out B, and just put some parts of the same color there

Robophone from RJ-45 socket outlet

I install an RJ-12 socket

Please note that this socket can be placed directly in any order

Everything is becoming more and more clear here

1) If you need to connect your home telephone with an RJ-11 connector. Then 2 lived (if any) are connected to 2 and 3 lived in the socket 2) If you need to connect your home telephone with an RJ-12 connector. Then 4 lived plugged in until all lived in the socket. Here you need to connect

There is a split in the connections, but I won’t describe how to make a living from such a box. Because everything is clear on the diagram

That's all for now :)

Yak z telephone cable zrobiti merezheviy (vita pair)

How to create a hemstone from a telephone cable (twisted pair) kolasaseg wrote in dachnyDecember 8th, 2015 Having installed a bunch of cameras here - work at the dacha with video caution. IP cameras, which are digital, transmit the signal via twisted pair, which is not found in the home, but because of excess telephone cables. The idea came to mind to crimp a telephone cable (thanks to the RJ-45 connector and crimping tool) under a twisted pair. I remember that there are not 8, but 4 twisted pairs in a hemmed cable, like in a telephone cable. Before speaking, there is a telephone with only two wires, this is definitely not suitable. Having searched on the Internet for the de-pinning of a 4-wire torsion bet:

When transmitting a signal over twisted pairs to a cable of category CAT5 (speed up to 100 Mbit/s), only two pairs of wires are connected to the cable. One pair is for receiving the signal, the other is for transmitting. 4 pairs required for speeds up to 10,000 Mbit/sec. We don’t need such people, don’t stop asking Skolkovo, they need more there))) You also know the old border card, which also has only 4 contacts:

For any color of wiring it will not be appropriate, so that at the end it will be the same. I made black, purple, green from the first to the third pin, then skipped the 2nd pin and the yellow one after the pattern. The other end is like this:

How to properly crimp an Internet cable with 4 wires

When carrying out local cabling in apartments and private cabins, the problem often arises with the cabling cable being squeezed. However, due to the availability of all necessary tools, this operation will not be performed. And all this is because the RJ-45 cable has its own characteristics, which require insurance when carrying out such work.
And today we will look at how to properly crimp an Internet cable with your own hands. For this purpose, you will need to prepare singing instruments and carefully read the instructions provided.

Features of hemstone elements

Most often, RJ-45, which is connected when a computer is connected to a local network, is called a twisted pair. This cable consists of 4 or 8 small wires intertwined in pairs. The skin washes its thick membrane. Why is the pair twisted? Everything is very simple - a cable like this allows you to reduce interruptions during the passage of electrical signals. Before speaking, if you are connected to the Internet with a speed of up to 100 Mbit per second, to carry out electrical signals, it is enough to use only two pairs, so that the fractions are lost. However, to achieve high-speed gigabit connections, you need to use cables with 4 pairs. Fahivtsi confirm that the availability of such conductors in the future will become even wider. However, still in most booths where cable Internet is installed, RJ-45 is used instead of wires.

Methods of pressing

Usyogo has two methods for pressing a hemlock:

Schemes for both can be seen in the photo below. As a matter of fact, with the direct option, the end of the cable may be damaged, however, due to the loosening of the conductors in the connector. The overlapping method ensures that the pair is crimped on different sides of the cable. Which one has a different order of connecting conductors.

What is the best way to connect a home network? Everything is very simple - a direct way to compete in these situations, if one computer is connected to the Internet. The overflow system only works if there is a need for two computers to be connected to each other. So, if you have one laptop or PC at home, it is better to quickly connect it directly with a cable.

How to compress an Internet cable at home? Prepared tools

In fact, you can turn with a twisted pair with bare hands, since you don’t have a great idea about local boundaries. As for the tools, they can be bought at any local computer store, and for a low price. Well, what do we need to do:

• 1.5-2 meters RJ-45 cable.
• Special connectors.
• Kovpachki.
• Scalpel or bokoriz.
• LAN tester.
• Well, and most importantly - a tool that allows you to crimp a twisted pair cable in a few seconds. It's called a vin crimper. This can be added at a price of 500 to 2 thousand rubles, depending on the modification, as well as the number of functions that need to be added. This will help you fix the connectors and crimp the cable. This device has a mechanism like pliers.

How to compress a “4 wire” Internet cable? Let's get started

Once you have prepared all the necessary materials and tools, you can start the robot. Before crimping the Internet cable, you must first remove the outer insulation from it. To connect, it is enough to remove 2.5-3 centimeters of insulation from the hole. You can remove the plastic casing either with the help of a knife or with the help of the crimper itself. In addition to many tools for pressing, a special blade is used to remove the insulation from the twisted steam from the sealed ball. After this line of wires, a thin nylon thread will be visible - it can be easily cut.

Before speaking, when stripping the cable, the twisted pair should not exceed 1.25 centimeters. To make it easier, you need to quickly use special pliers, which are used to handle knives between edges.

How to crimp an Internet cable? We separate two twisted pairs of conductors and align them to carry out subsequent operations. After preparation, you can begin the pressing procedure. Try to be timid strictly behind the scheme.

Please note that before processing the twists, the bet with a crimper must be as equal as possible, and the arrows must be spread out parallel to each other. If required, you can short-circuit two positions in the order of the conductor. Try to get help by climbing onto the crimper.

Robot with crimper

Next comes the most common part of the work. Then, stretch the connector and carefully squeeze it with a crimper. For this purpose, conductors are inserted into the connector of the RJ-45 cable. It is important to remember that all colors are related to each other, so white connects to white, blue to blue, and so on.
Let me make one small point here. Before crimping the Internet cable, make sure to ensure that different wires are connected to the connector. True, there are too many types of elements. For example, instead of blue you can use white-blue, instead of orange you can use orange-blue.

Also, make sure that the conductor of the increase in the leads opens on the connector. Otherwise, transferring data, and obviously, to the Internet on a PC will be impossible. Having switched to the correct color scheme and the placement of conductors, we take a crimper and crimp the hemline cable. Here's how to do it: the cable and connector are inserted into the device and the handles are pressed together. Please note that this element has a number of openings for different types of wires (4P2C, RJ-12 and many others), and three. For the RJ-45 cable itself, this opening is located in the middle.

Verification of robot results

But the problem of how to squeeze a 4-wire cable for the Internet with a hand is still not complete. Next, it is our responsibility to check the correctness of the work. You don’t have to rely on the tactical method, but on the help of an additional special device - a LAN tester. How to use this tool? First you need to insert the cable connector into the tester. Further devices are connected until live. If the tester does not detect the same errors, all the indicators will light up one by one. As you noted, the tool “missed” one of the conductors (without lighting up one indicator), which means that the socket has inappropriate contact contacts. For this type of installation, the hemstone cable must undergo a repeated pressing procedure and be tested again.

Why bother if repeated pressing did not solve the problem?

In this case, the problem may lie in the connector. It happens that at the entrance, people can get confused with someone else, and therefore it is simply impossible to guarantee the strength of the contacts. Try replacing the connector with a different one. Most often this helps when connecting a local network.

Visnovok

That's it, at this stage our cable is ready for use. Similar to the above-described fall, the other end of the dart is formed. After this, you can calmly lead him to the computer. Heads up here - don’t forget about the order of connecting the conductors.
Well, we learned how to wrap an Internet cable with a hand. As you see, the whole procedure is very simple and understandable, and it takes every little bit of effort.

Blog / On the first smoothie / Crimping RJ-45 and conductive 4/8 wire mesh cable

We crimp RJ-45 and conduct a 4/8 core stranded cable

After connecting the cable from the router to the computer. Having bought a cable channel three years ago, only a few hands reached them :). I don’t remember, if I’ve been busy with pressing the RJ-45 for the last time, thinking about it, thinking a lot. I share.

What do we need?

We select the cable and lay it

Measure from point A to B for as long as you need the cable. Just imagine how it will fit in the cable duct or be attached to the walls. Perhaps you are going to grab it under the baseboard. Before laying, be sure to call the cable :).

Before the “pressing” operation, the cable must be laid, leaving an adequate supply at the ends. For example, it is important that a computer with a cable connected can be hung from the niche, turned on, or connected to the system unit without the need to install wires.

The cables for laying the hedging are double-stranded and have twisted pairs of wires. You will need to be one of them, but 4 live (for a total of 2 pairs) will allow you to connect only at a speed of up to 100 Mbit. Such a cable is cheaper, easier to crimp, and often more flexible is not required.

To be honest, the skin pair of veins is marked with its own color. For example, orange wire of weaves with white-hot wire. The skin from the steam is absolutely not damaged in any way other than the color of the insulation. In the connection and compression diagrams, you must first specify the colors of the wires, but in fact, if you interchange two pairs, everything works exactly the same way.

Connector RJ-45

The exceptionally clear body of the connector shows 8 gold-plated contacts. The numbering of contacts from 1 to 8 is shown in the image.

To squeeze, we only need a couple of such roses-connections. It’s never a bad idea to take a few pieces in reserve.)

Squeezing pliers

There are three types of operations on the baby that allow you to remove the pressure pincers.

Cleans the core insulation of the cable. The knives (1) do not close completely, and the wires can be routed against a special strip. The bar allows for optimal cable length (approx. 1.5 cm). When removing the insulation, the end of the cable can be turned and a knife can be used to cut the dry ball into a stake.

Crimping RJ-45 connector. Clamps (2) are used at the very end if the conductors are missing from the required channels. The toothed edge presses the contact blades against the conductors, and a special protrusion inserts the RJ-45 dart retainer.

Nizh. The third typical element of pressing pliers is used for aligning conductors and cutting cables. This bottom surface is cut from the protruding edge, which works like a wire cutter.

What are we getting together?

There are two types of connection, so we need to know what we are connecting with. The greatest expansion is when we connect the computer to any device that switches - a router, a switch, a switch... Here we have a direct connection scheme (workstation - hub).

Direct connection scheme

You will need to create a completely new cable crimp at both ends for this circuit. Choose a picture for your connection - 8 or 4 were in the cable.

The order of color pairs is shown for the butt. Instead of the orange pair before contacts 1 and 2, you can connect, for example, a green pair. Ale offense connectors guilty buti divorced on the ends of the dart however.

Cross cable routing diagram

Another type is the connection of two concentrators or two work stations. In this scheme, it is necessary for the orange and green pairs at the ends of the line to be swapped.

RJ-45 crimping process

1. Remove the outer insulation of the cable with pliers.
2. Unravel and place the conductors in the required order.
3. Insert them into the channel with an RJ-45 connector for fitting, so that they take the shape of the channels and straighten out.
4. Remove them and, if necessary, trim them with pliers.
5. Re-insert them into the connector channel, turn everything over so that everything is in its place and the skin guide goes all the way into its channel.
6. Use the pressing pliers.

I recently started working on an online game. This is not a problem, but it’s not about that yet. Perhaps, I’ll write about this later. At the point where I was about to create an online game, I was faced with a modest choice.

Color circuits for embossing (pinning) the twisted pair cable (patch cord) on the RJ-45 plug

In accordance with the EIA/TIA-568 specification, a number of colorful circuits are transferred to the lan cable of twisted pairs (patch cords) into the RJ-45 connector for connecting computers with a router, hub, plug, or connecting two computers 'Yuteriv among themselves.

What is the capacity of a patch cord for a twisted pair cable? A patch cord, or a patch cord, is used for connecting electronic devices together, for example, a computer with a hub, or two computers with each other. To prepare the patch cord, use a cable of twisted pairs and use a high-vein wire in such a preparation, so that the stench does not break with frequent changes. To connect such a cable, special RJ-45 connectors are used. According to the ANSI EIA TIA 568B.1 standard, the patch cord is not required to exceed five meters. Connecting devices behind an additional patch cord is cost-effective, since they often move one by one during operation.

In all the photographs below, one LAN cable is shown, intended for installation in LAN (Local Area Network) and DSL (Digital Subscriber Line) networks, with RJ-45 twisted pairs pressed at its ends.

Color diagram for embossing an RJ-45 torsion cable on a computer - hub for the Internet

Color marking is applied to the lan cable of torsion paired with option B, the most extensive option.

Color marking is pressed onto the lan cable of the torsion pairs for option A. As can be seen in the photo, in both options the ends of the lan cable of the torsion pairs are routed and pressed into the same electrical circuit, only in places the two torsion pairs are changed and. At the place of orange torsion the bet is compressed with green. and in the place of green torsions of the bet - an orange one.

Both pairs are connected to the lan cable, crimped as option A and option B are interchanged. So, you can choose any color scheme option, as is more appropriate, but it will not affect the usefulness of the lan border.

Color diagram for RJ-45 cable torsion pair computer - computer

If you need to create a local network with two or more computers without the need for additional active equipment (hub, switch or router), for example, for collective games, then for which the EIA/TIA specification is used for cable processing yu twisted steam. To create a connection from two computers, it is enough to insert one such twisted pair cable into their connection ports.

Please note, the lengthy ends of the lan cable of the computer-computer twisted pairs are pressed together behind different color schemes.

The RJ-45 twisted pairs are crimped using a tool called crimping pliers. Since there are no pliers under your hands, you can speed up the technology of pressing torsion pairs without pliers.

All the color schemes for the lan cable spinning of twisted pairs are currently losing their relevance. Current network cards, switches, hubs and routers, which are based on Auto-MDIX technology, automatically determine the type of twisted pair cable and design the internal structure. So, a current computer, with the connection created, can be connected to either the hub or another computer, without worrying about the color scheme option for the twisted pair cable.

Color scheme for embossing RJ-45 cable with 4 darts of torsion for the Internet

When you connect your computer to an Internet connection or create a local network, it is rare that the twisted pair lan cable is capable of running completely. This, of course, is related to the variety of information.

When transmitting a signal over twisted pairs to a cable of category CAT5 (speed up to 100 Mbit/s), only two pairs of wires are connected to the cable. One pair is for receiving a signal, the other is for transmitting, which is clearly demonstrated by the electrical diagram of connecting a computer's edge card with a twisted-pair cable with an RJ-45 connector to a plug-in hub or router.

As you can see from the diagrams, a two-pair lan cable is connected to the computer and hub or router behind a symmetrical transformer circuit. The advantage of the transformer circuit lies in the suppression of induction and transients and the provision of high-level protection from short circuits and breaks when installing torsion pairs in the cable.

When it is necessary to lay an additional line or when the pairs of a long cable are frequently damaged, it is possible to increase the strength of the additional line without compromising the speed of data transmission Or repair the cable of twisted pairs by crimping the RJ-45 plugs on previously uninstalled pairs.

The color diagrams below the RJ-45 twisted-pair cable are not visible above the guides, but only show the conductors of the twisted-pair cable that are wired to transmit information. Any pairs that do not come close to the RJ45 plug are compressed, otherwise the signal is not transmitted through them and they can be used to transmit additional information.

Crimping twisted pair, option B. The signal is transmitted in orange and green pairs.

Crimping the twisted pair, option A. The signal is transmitted only through the green and orange pairs, but the twisted pairs are pressed at the RJ-45 fork to other contacts.

If, when inverting the cable of the twisted pairs, a break or short circuit was found in the orange or green twisted pairs, and the blue and brown ones are referenced, then you can do without replacing the cable. It is enough to re-press the twisted pair cable with an RJ-45 plug along one of the lower color schemes.

Crimping of pair torsions during the repair of option B. The orange torsion pair was replaced with a brown one. and green is blue.

The twisted pair was pressed during the repair of option A. The orange twisted pair was replaced with blue. and green is brown.

As you know, if the twisted pair is incorrect, you can replace it with a non-corroded pair, blue or brown.

A twisted RJ-45 pair for connecting two computers via one cable can be wired using this color scheme.

Two left RJ-45 plugs are inserted into the edge cards of two computers, and two right RJ-45 plugs are inserted into the active power socket. Otherwise, the symmetrical cable has been broken.

Sometimes there is a need for additional low-voltage wiring from the entrance doors to the room. For example, you need to run a pair from the socket near the entrance to connect a landline phone. power the antenna booster with constant voltage, supply power to the Wi-Fi router or Switch, connect the additional intercom handset, install an additional apartment call, install an intercom device with remote controls for the entrance doors, power the low-voltage I'll add one light strip for illumination before rest. In this case, it is possible to successfully vikorystvovat free pairs in twisted pair cables.

Respect! The transmission of 220 V power supply through the cable of twisted pairs is categorically fenced off, since the cable of twisted pairs of the Internet is not covered by insurance for such voltage. It’s not safe for life and you can get your computer out of trouble.

The diameter of the wire conductors in the cable of twisted pairs should be set to 0.51 mm (crossbar 0.20 mm 2), which allows the passage of currents through them with constant pressure of up to 1.5 A, and with short-term pressure up to 3 A. And if connected in parallel along two wires, then the permissible current will double and become 3 A. Then, if we connect all the conductors of the twisted pair cable in parallel, we will be able to transmit currents from them up to 12 A!

Now available for sale is a cheap twisted-pair cable with steel cores enclosed in a thin ball of copper. When transmitting a high-frequency signal to a small cable, it is entirely possible to jam such a cable, although the reliability of the circuit will be reduced. When testing twisted-pair cables with steel conductors to transmit the life voltage, it is necessary to protect them, so that the voltage is an order of magnitude lower than for a cable with conductors made of pure copper.

To realize this possibility, it is necessary to squeeze the RJ-45 lan cable into the fork in one of options A or B, without squeezing the brown and blue pairs, and then vikorist those other pairs to the authorities. It is necessary to use reliable conductors so as not to use Internet resources. How to properly install wires You can find out in the article “Installation of twisted pair cables.”

The color scheme for embossing an RJ-45 cable of twisted pairs consists of two twisted pairs

Currently, a cable of twisted pairs has gone on sale, which instead of the traditional ones has only two twisted pairs. And this is economically corrected, and in 90% of cable lines for the Internet, only two spins of the bet are used.

As you can see, the electrical circuit for connecting the rj-45 pins has not changed, only the blue one is compressed instead of the green pair.

Such a cable of twisted pairs, option B, is crimped according to the diagram shown above in the photograph. When pressing for option A, the bets simply switch places. Instead of the orange pair, blue is squeezed. and instead of blue - orange.

This article shows how to squeeze the cable of a twisted pair, 4 wires. If you are talking about twisted pair cables, then in most cases there are eight-core twisted pair cables, if you have such a cable, read the article for instructions: how to crimp a twisted pair cable of 8 cores.

The 4-core wire mesh cable is twisted in pairs, becoming popular during the period of massive expansion of wired Internet in the region. Everything on the right is that in a straight line with an 8-core cable it costs twice as much. Therefore, providers, in order to save pennies, like to impose a fee when connecting to the drone Internet. Another feature with a 4-core cable is that it offers data transfer speeds of up to 100 Mbit/s. If you have a 100-megabit network adapter on your computer or laptop, then you can use the network adapter or patch cord for an additional 4-wire cable if you plan to install a gigabyte network, choose an eight-core cable.

This is the case with an eight-core cable. This is the same RJ-45 connector, squeezing pliers and the necessary maintenance itself is extremely important.

Schemes for twisted pairs, 4 wires

It is important to know here that there are different options for color marking of conductors in a twisted pair cable. Lower down on the little one, there is a circuit for pinning and wiring, for wrapping a 4-wire cable with torsion pairs (there are a number of options).

If you have such an option for barring conductors. then the ripple will come:

Alternatively, instead of white-green and green, white-blue and blue are used.

The split of the twisted bet will be like this:

On the little one below, overhauled, perhaps, all the color schemes of 2-pair torsions of the bets are sharpened. The head remembers the numbers of the assigned contacts: 1, 2, 3 and 6

Use the diagram below to create a crossover cable when two computers are connected in the middle.

Well, that’s all there is to the theoretical part of embossing 4-way (2-pair) bet twists. Practical details (how to squeeze) were given earlier in the statistics - how to squeeze a twisted pair. read, marvel at them there. Once the article is complete, watch the video where I show you how to squeeze a twisted pair of four veins.
