Self soldering butt splice
« on: September 28, 2018, 07:30:35 am »

Just saw these on my facebook feed. It's a butt splice with a low-temp solder/flux slug, plus low-temp glue seals on the ends. So you just strip the wires, plug them into the splice, and melt the low-temp solder with a heat-gun or maybe a lighter. In theory this melts the solder to connect the wires, and also melts the glue to form a watertight seal. While I scoffed at this at first, it's actually an interesting idea for my RV readers who have no real soldering skills, and yet are installing new fans and other gadgets in their RVs. Perhaps is this even acceptable for 70-volt speaker splices in a ceiling rather then wire bugs. What do you all think?

I like it, mostly, but solder should not be trusted alone... there should be a mechanical connection first, then solder to perfect it. That looks like it could easily pull apart if reheated.

Perhaps better than what they are doing now?

[edit- perhaps a soft tin sleeve that can be crimped before the low temp solder is melted could provide some mechanical strength. My old mil spec soldering training is showing... 8)  [/edit]

These have actually been around a while, car audio guys like them for working in cramped areas. A guy did a side-by-side of using an iron vs using these, no real time saved between either joining method and both held solid. He noted that the solder in the shrink connectors actually did a good job of penetrating through all the wire strands when he snipped them with some dikes, so continuity shouldn't be an issue if used properly.

JR brings up a good point about reheating, but if your wiring is in a place where it gets hot enough to reactivate the heat shrink (200+ F) then you may have bigger problems or need to address proper insulation.

1) Do it right
2) Do it over until you do it right
