One of the most frequent breakdowns of electrical appliances is a broken wire for one reason or another. Everyone who is faced with a similar problem raises the question of how to fix the wire itself without the help of specialists. There are two main ways to repair any cord: twisting or soldering.

The main causes of the cliff

How to fix a torn wire

If the wires break near the plug, then it must be replaced.

Because of what a break can occur:

  • careless user actions that resulted in mechanical damage;
  • frequent deformation and bending during the operation of the device - for example, the cord on the headphones in the area of ​​the plug connection;
  • damage by pets or rodents.

If you find a broken wire, the appliance connected to it must be immediately disconnected from the network or the connected device.

Ways to repair a torn or gnawed wire:


Twisted wires

Twisting in flexible wires is better not to use

In this case, you need a minimum of tools:

  • side cutters;
  • knife;
  • insulating tape or shrink tubing.

You must perform the following steps:

  1. Peel off the cord from the polyethylene insulation so that the metal parts of the required length can be seen to twist them together.
  2. In case you want to connect the wiring from the headphones, you must also get rid of the lacquer coating, which does not allow the contact to take place. To do this, you can gently clean them with a sharp knife or fine sandpaper.
  3. Twist the stripped ends of the broken wires together for at least 4–5 dense turns, observing their color marking. After that, use the side cutters to remove the tousled ends of the conductors so that the twist is neat.
  4. Insulate each wire in place with electrical tape.

You can also use a special heat shrink tubing, which should be put on twisted wires and heat over an open flame or other heat source so that it is tightly wrapped around the place twist.


Soldered wire

When soldering wires need experience and skill

This is a more reliable method that will provide good contact at the point of rupture and resistance to mechanical stress.

To perform the soldering will require:

  • soldering iron;
  • tin;
  • rosin or another type of flux;
  • insulating tape or shrinking;
  • side cutters;
  • knife.

You must perform the following steps:

  1. Strip the ends of polyethylene and varnish insulation.
  2. Twist the torn conductors according to the color marking for 4–5 turns.
  3. Using flux, solder the place of twisting so that the tin evenly spread at the junction of the wires. A sign of good soldering is the characteristic brilliance of the solder on the connected conductors, but its matte the shade may indicate that the soldering iron was too overheated or, on the contrary, the soldering temperature was insufficient.
  4. Make insulation in places soldered with insulating tape or shrink.

If you compare both ways of fixing the wire, then the soldering is far superior to twisting in reliability. However, working with a soldering iron requires experience and accuracy, so it is best done by a professional. Twisting is much easier, but this method is short-lived, because the wire can again be broken and damaged.
