Heat Shrink with Solder - Page 3

WillyHeckaslike · 14th April 2019, 13:55

I've seen them used to good effect by someone using nothing but a zippo lighter. In fact the zippo was his preferred technique for use with solder sleeves when the environment allowed for it as the heat from the flame could be more accurately focused on the solder ring to obtain a good melted flow with less risk of frying the whole of the plastic sleeve. The two meltable glue rings either side of the solder ring provide good support for the joint and weather proof it too when a proficient standard is reached. I think that it is like soldering itself, practice makes perfect but for me I never had the need for solder sleeves and I just stuck to what I knew best - plus solder sleeves were relatively more expensive when I first looked at them which was many years ago.

It seems that when you heat the heat shrink it solders the wires together.
Seems like a good plan.
Has anyone used them, are they any good?

These are supplied (MGR originally and to this day by Rimmer Bros.) as part of the repair kit for the airbag plugs under the front seats. I used them to fix the dreaded SRS light problem that bedevils our babies - use these and follow the appropriate MGR TSB and hey presto, no more random SRS light/potential MOT failures.

One of the points about the solder sleeve is that the shrink outer provides strain relief. If you twist the wires together and solder them you need shrink sleeving (or similar) to cover the joint to well beyond where the solder has travelled up the strands inside the insulation. I like crimps.

I was involved in a project with a sonar transducer array and no strain relief on the connections, perhaps it didn't need a full array....

Anyone tried WAGO 222 Series connectors?

I've used them on 230v house wiring and they're fantastic for solid wires - once the clamping lever is down you can't pull a 2.5mm2 solid wire out of the connector. I've never tried them on stranded wires but the blurb sheet says they're suitable.

They have one huge advantage over solder - you can release any or all of the wires just by flipping the levers back up. They're much quicker to connect than soldering. And you don't need heatshrink or insulating tape.

Available in 2, 3 & 5 wire options.

A bit dear but well worth it IMO.

Wago 221 - smaller than Wago 222 but just as good. Pause at 9 sec to see them next to each other: https://www.youtube.com/watch?v=n8gLG6c-iKc. Available in 2,3,5 lever options.
