An innovative way to connect two wires

March 1, 2019 Electronics / Useful and interesting 510 007 39

Progress does not stand still and a simple heat shrink to insulate the wire will not surprise anyone. Therefore, now we will talk about a completely new and innovative way to connect two wires without soldering, twisting in a couple of seconds.
New connectors 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 isolates, but also solders the wires with internal solder!
It looks like a fantasy, but let's take a closer look at where to buy and how to use it.

Will need

A hairdryer, a pocket gas lighter is also suitable.
Special heat shrink tubes for splicing wires. You can buy .

One tube consists of several components:

- insulation itself, heat shrink,
- two crimp rings on the sides - contributing to the complete sealing of the entire connection,
- and a central ring with flux and solder.

Connect stranded wires

Now practice. First of all, we select the tube of the heat-shrinkable connector for the diameter of the connected wire (which is why it is better .

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

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

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

Turn on the hair dryer and carefully blow the heat shrink.

In order for the tube to lie flat on all wires, it is advisable to start blowing from the middle.

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

Then let the mixture cool for a couple of minutes.

Total:

The result is a moisture-resistant, high-strength connection of two wires. It turns out much faster in time than with classical twisting.
Neither tinning nor stripping of wires is necessary. Active flux and solder inside will do the job.

Since a pocket gas lighter can be used instead of a hairdryer, such connectors are just a godsend for car enthusiasts.

And how long will this spike last? After all, the flux is active, which means that everything will eventually corrode inside.

  The junction, as written in the article, is moisture resistant.And corrosion without access of oxygen and water is very difficult :) Another option is whether it is moisture resistant or like ordinary heat shrinkage, but the video does not look bad ...

  In aviation, solder sleeves have been used for a very long time. The first AIRBUS-320 left the factory over 20 years ago. One of these is now at our TO (S7 Technics). All wires and connections are as new. No corrosion.

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

  Last summer I bought a lambda for replacement. In the set there were just such heat shrinks. Very convenient ...
  and under the hood: water, temperature, and dust ... it keeps excellent. if I see it, I’ll definitely buy it for myself.

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

Better at first to dip the wires in liquid rosin.

you can just solder, 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 in radio electronics and weak. In power circuits it will be useless.

In the car, the wires do not solder, they break off very quickly at the place of soldering.

He worked as a radio installer, we had a memo on all the walls at the factory, soldering provides improved electrical contact, soldering does not give a mechanical connection, without normal twisting, this is nonsense, no one bothers to twist the flux and sing it normally, but this is a beautiful photo.

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

This is called active flux cold soldering. Worse than twist.
I did not see such devices, but I saw cold soldering with an active flux. There is experience. Enough for half a year. At best, three years. Then, at best, there will be a cliff. At worst, increased resistance, heat, fire.

And what's new and revolutionary. When repairing a Renault car, the manufacturer recommends such things. About ten years ago she was shown to me in a training center. As they said then, not everyone knows how to use the holiday, so here is a safe way for you to sing the wires.

Such heat shrinkage was used in the early eighties at the enterprises of aerospace units (read in the mailbox).

I do not see any innovation. twist the two ends by air twisting, solder normally, put on heat shrink. All!

Six months already stands in an aggressive, very humid environment, the aquarium lights up, the flight was normal before that every three to four months, exactly, the compounds were “driven away”. But for something more powerful, I would not risk installing such tubes, especially as they suggest connecting the wires themselves, you still need a full twist.

There is nothing better than sleeves and crimping pliers, 100% contact, a monolith is obtained in the place of crimping!

Cool thing. I sometimes use it myself. Of course, the price is more expensive if you use conventional soldering and heat shrink. But when there is no electric soldering iron nearby, it helps out with a bang.

In the late 70's, my father received a copyright certificate for this method of soldering. He launched the production line of TU tubes in Maloyaroslavets. It was the USSR and its development was used in NPO Energia.
It was nice to read that progress does not stand still and the method of soldering is “innovative”.

  In the 80s he worked for NPO Energia in a cable workshop. Soldered the wires and planted a heat shrink or PVC pipe with glue BF-6, alcohol ..

This is all beautiful, but in practice it is indispensable. If the wires are already black (oxidized), then no flux will help to solder them. This time. Second: this method is not suitable if you need to make a branch of the wires (insert more than 1 wire on one side). In both cases, the crimp connector with heat shrink and adhesive inside solves the problem.

So far, no one has come up with a better twist, but if it is still soldered, the demolition century will not. And this soldering is not very reliable. It will heat up under load ... Everything is very unreliable.

this garbage is at least 7 years old already or more, I worked as an electrician in a reputable office and my superiors took a sample of them for solidity and just checked. As it turned out, the idea was not bad, but damp, the solder could not withstand mechanical loads on bends and fell apart, the heat shrink hardened very quickly. also soldering did not always qualitatively grasp the ends of the wires (as if they had to be tinned). As a result, we refused and returned to the sleeves under the crimp with heat shrink overlay. More reliable
