Anyone idea what these items are called basically...

You have what looks like a a straight through electrical crimp with a see through bit in the middle (with solder stuff in), you insert each side of a wire and hold cigarette lighter in the middle, in then melts and solders the two wires together.

 

Ooops looks like I've put this in the wrong section.

 

Not seen ones with solder in the middle, but if it helps, the name of a standard 'straight through' crimp terminal is a Butt Splice. So I suppose what you're after is a 'solder filled butt splice'?

 

Solder heat shrink splice.

I love soldering stuff

B&Q or maybe Halfords will sell such things.

I prefer to mechanically connect the wires (entwine) then solder and wrap with electrical tape.

 

Me three.

But I was recently informed that solder & high-vibration areas don't mix, so that's why crimp connectors are preferred.

Not those nasty, dangerous pre-insulated ones that the accessory shops sell; the proper ones.

 

i dont buy into that.
how many soldered connections do you think are in a car? ecus, relays, head units, etc etc etc. i know some of the older hondas had issues with the main relay - resolder the points and everything is good again, but that was early 90's models.

 

Thanks, I love soldering too

 

Proper solder and heat shrink as above.

Heat shrink is fascinating to do and watch as it shrinks (And you can make it sooooo pretty which brings such a sense of achievement).

 

They're solid state, though. This is more related to wiring, where there is movement.

I'm a bit sceptical myself, TBH.
