NTE Electronics Heat Shrink Self-Solder Butt Splice Connectors

Anyone use these?

Looks like they'd be convenient in some applications, and there are some fine gauge connectors.

Been around many many years were called environmental splice in the industry I was in, although we only really used them for terminating the shield on shielded cable to a tail that would be grounded or last ditch field repairs to be done properly at end of deployment (pull the whole wire and replace it).

The only drawback is you need a mains powered heat gun to set them properly I think the solder in them has a relatively low melting point, anything with a flame is most likely going to burn them and we were using them on Teflon coated wire not sure how they would go with the regular pvc coated stuff as in automotive applications i.e. would it just turn into a gooey mess.

I usually screw it up by getting it too hot or not having it positioned just right when it goes so I don't like to use them. I like the crimp type with heat shrink already on it.

Looks dandy in an application where the wires are easily accessible. Not so much for repair of already mounted wiring in a tight area.

I used those many years ago. The heat shrink with glue makes a nice sealed connection.
Takes a lot of heat. And you need to sort of guess if the solder flowed properly.
I still prefer a good crimp and separate heat shrink..

      Another weapon in the arsenal for splicing. The fact that they're clear is a plus.

Looks like a comment re lugs vs butt connectors from Kiwi Roy may have disappeared!?

I would think that the same sort of system could be used to attach terminals to a wire. I did a quick search and didn't see anything. This could be especially useful for thin wires that I find hard to crimp.

Whenever I have used them we had an attachment on the heat gun that warped partially around the wire and concentrated the heat onto the splice. This made the heat gun a lot more efficient as not as much heat was wasted and less heat into the area you are working.
