An innovative way to connect two wires

An innovative way to connect two wires

Progress does not stand still and a simple heat shrink for wire insulation will no longer surprise anyone. Therefore, now we will talk about a completely new and innovative method of connecting two wires without soldering, twisting in a couple of seconds.
New connectors have appeared on sale that not only insulate, but also solder the wire inside the insulation itself. It is very similar to a simple heat-shrink tube, but unlike it, it not only insulates, but also solders the wires with internal solder!
It looks like science fiction, but let's take a closer look at where to buy it and how to use it.

Will need


  • A hairdryer or pocket gas lighter will also work.
  • Special heat-shrinkable tubes for splicing wires. You can buy Ali Express.

One tube consists of several components:
  • - the insulation itself is heat shrink,
  • - two crimp rings on the sides – facilitating complete sealing of the entire connection,
  • - and a central ring with flux and solder.

Connecting stranded wires


Now practice. First of all, we select the tube of the heat-shrinkable connector to the diameter of the wire being connected (this is why it is better buy a set of these tubes).

Remove the insulation from both wires, about 1 centimeter on each side. Next, we put a connector on one of the ends.

We connect the fluffy veins by inserting them into each other so that they are intertwined with each other as much as possible.

Then you can squeeze this twist a little by hand and put on the connector tube so that the solder ring is exactly in the middle.

Turn on the hairdryer and gently blow on the heat shrink.

To ensure that the tube lies evenly along all the wires, it is advisable to start blowing from the middle.

And as soon as the wires inside are soldered, we begin to blow on the side moisture-resistant rings.

Then let the connection cool for a couple of minutes.

Result:


The result is a moisture-resistant, high-strength connection of two wires. In terms of time, it turns out much faster than with classic twisting.
There is no need to tin or strip the wires. Active flux and solder inside will do the trick.

Since it is quite possible to use a pocket gas lighter instead of a hair dryer, such connectors are a godsend for car enthusiasts.

    And how long will this spike live? After all, the flux is active, which means everything will corrode inside over time.

      The connection point, as written in the article, is moisture resistant. And corrosion without access to oxygen and water is very difficult :) Another option is it really moisture resistant or like regular heat shrink, but it doesn’t look bad in the video...

      Soldier sleeves have been used in aviation for a very long time. The first AIRBUS-320 left the factory more than 20 years ago. One of these is now in our maintenance facility (S7 Technics). All wires and connections are like new. No corrosion.

      In addition, it uses Rose alloy, which in some situations - heating more than 90 degrees - will greatly reduce the strength of the connection

      Try it. If you're interested. Dream up.

      The flux may not be active.

    in principle, not bad, I haven’t heard of this, I have two questions for the author, 1 the price of the issue, 2 where it can be used, street, dacha, and reliability

      Last summer I bought a lambda to replace it. The kit included just such heat shrinks. Very convenient...
      and under the hood: water, temperature, and dust... holds up perfectly. If I see it somewhere, I’ll definitely buy it for myself.

      I saw this already 2 years ago. normal lives. moisture-resistant rings, flux does not corrode copper (oxide is not particularly visible)

    It’s better to dip the wires in liquid rosin first.

      And rosin will spoil the effect of standard solder and flux..

    Great idea, but wouldn't it be easier to use solder paste?

    you can simply solder it, after putting on the appropriate heat shrink (and it costs a penny) and warm it up! That's all. And this solder is fusible! Why is it needed??? if the current is used for radio electronics and low current. It will be useless in power circuits.

    In a car, wires are not soldered; they break off very quickly at the soldering point.

    I worked as a radio installer, in our factory there was a notice hanging on all the walls: soldering provides an improved electrical connection, soldering does not provide a mechanical connection, without normal twisting, this is nonsense, no one bothers to twist normally, cover with flux and solder, and this is a beautiful photo.

    Inside the car, soldering is not used, only twisting. and who will forgive this active flux and then wash it out from there?

    This is called cold soldering with active flux. Worse than twisting.
    I have not seen such devices, but I have seen cold soldering using active flux. I have experience. Enough for half a year. At best, three years. Then, at best, there will be a cliff. At worst, increased resistance, heating, fire.

    What's revolutionary and new here? When repairing Renault cars, the manufacturer recommends such things. Ten years ago they showed it to me at a training center.As they said then, not everyone knows how to use the holiday, so here is a safe way for you to solder the wires.
