Connection of wires without soldering

Connecting wires is a fairly common operation. Most often, many of us, without having a soldering iron at hand, do the usual twisting in this case. But twisting, as you know, is a rather fragile connection. It can be torn apart with quite a bit of physical effort. Yes, and electrically, it is not particularly reliable.

If we are talking about connecting stranded wires, then twisting can be done in a slightly different way. It is about this method that will be discussed in today's small article. The resulting wire connection is reliable in every respect.

Preparation of connected stranded wires

It is quite clear that it is impossible to connect wires without stripping them. To do this, you can use, for example, a sharp clerical knife.

In order not to damage the wires and perform the stripping perfectly, read the recommendations that we give here. in this article.

After stripping both wires to be connected, their cores should be thoroughly fluffed up so that a kind of tassels are obtained.

Now the conductors are completely ready to create a strong twist.

How often do you strip wires? Why don't you buy an inexpensive and reliable stripper?

Wire connection

Compliance with the order of connection of stranded conductors is the key to the strength and reliability of future twisting. To ensure its maximum reliability, wire brushes should be passed one into the other. In this case, the cores of the conductors should be mixed as much as possible.

After that, the strands of the left conductor should be firmly wound onto the stripped part of the right wire.

A similar operation is performed with the cores of the right wire.

The resulting twist will look like this:

The strength of the twist can be verified using a dynamometer. Having fixed one end of the resulting conductor on the hook of this measuring device, we will pull its second end. The photo shows that even with a force of more than 6 kg, the integrity of the twist is not violated.

Strand insulation

To make the twist more durable and completely safe, it must be carefully insulated. This can be done with heat shrink or electrical tape.

If the insulation is made with electrical tape, it must be wound so that its layers overlap. It is necessary to ensure that there are not the slightest bare areas left.

As a result of the work performed, the following connection will be obtained:

So, using this method, you can get a very reliable and completely safe wire connection. In terms of quality, such a connection is practically in no way inferior to soldering.
