DIY Internet cable repair

In detail: do-it-yourself Internet cable repair from a real master for the site my.housecope.com.

It is no secret that modern technologies are developing rapidly, therefore, in order for us, their consumers, to keep pace with progress, we have to understand every little thing. Today the Internet has occupied an integral part of the life of society. To be able to set up a "connection with the world" at home, requires special knowledge.

You can clamp the contacts of the RJ-45 connector at home.

Surely each of us, sooner or later, will face such a problem as wear of a LAN cable for an Internet connection, a breakdown of an Ethernet connector, or a shortage of network cable length. To quickly solve this problem, you will need half an hour of time, knowledge of the algorithm of actions and a minimum set of components.

If you are interested in how to crimp a cable for the Internet using a special tool - crimping or without it at all, special crimping schemes and the details necessary for this - you are welcome.

Crimping is the attachment of an eight-pin modular RJ-45 connector to a twisted pair (network cable consisting of eight twisted pair wires). For this operation you will need:

  • Internet cable.
  • A pair of RJ-45 connectors... You will need one for work, however, their low price allows you to take one or more in reserve.
  • Crimp. He is a crimper, he is also a press tongs - a special tool for significantly speeding up the crimping process.
  • Insulating cap. Optional, but will help prevent subsequent bending of the wire and debris entering the RJ-45 connector.

Today there are two schemes for crimping a twisted pair - straight cable and crossover (crossover).

Typically the straight-through cable technique is used to connect:

  • Computer and switch.
  • Computer and router.
  • TV and router.
  • Router and switch.

Crossover cable crimping is less and less common today, since modern technology automatically detects the type of network wire and works flawlessly with both straight and crossover cables. The cross type is used to link the same type of mechanisms:

  • Router and router.
  • Switch and switch.
  • PC and PC.

The direct construction of colored conductors at both ends of the cable looks like this:

As for the crossover cable, here both ends of the twisted pair will be different, and the distribution of the cores looks like this:

Having decided on the scheme, we move on to the most important part of the whole procedure - crimping the RJ-45 connector using a special tool - crimping. The peculiarity of working with a crimper is that he significantly saves time and performs the critical part on his own.

You should start work by cutting off the old connector (if there is one, it will become a model for the location of the veins). Next, you should strip the twisted pair of insulation by stripping the colored wires so that their length matches the connector and they sit in it all the way. The outer sheath can be cleaned with a double crimping knife or a regular pocket knife. The colored veins will be twisted in pairs, so they should be disconnected, straightened and trimmed to the same length. Having arranged the wiring according to the selected scheme, we take the RJ-45 connector with the latch to the bottom. We insert the veins into it all the way so that a small part of the insulation of the Internet cable also goes into the connector. With the wires in their routing channels and the edge of the insulation under the RJ-45 clamp strip, it's time to crimp. We place the connector with the conductors in the tool connector.There are only a couple of strokes left - we squeeze the crimper handles so that the clamp bar (contacts) of the RJ-45 plug cuts through the insulation of the cores.
