There are several types of these terminals. Simple crimp, which is well
known, crimp/shrink tube, solder/shrink tube, and crimp/solder/shrink
tube. In other words, many different flavors for different PREFERENCES.
Even simple crimp connectors have many sub categories (insulated,
non-insulated, etc.)
Oh crap, fodder for another discussion....... More Rum!! Uh... and Beer!!
Don't expect these to cost the same as simple crimp terminals. I've used
them all, on smaller gauge wire (up to 8 Ga.), on vehicles, in high
salt/moisture conditions (i.e. roads during Michigan winters). I've use
"solder slugs" on battery cables in automotive and hi/lo applications in
severe use/vibration conditions without failure. If you can sweat copper
pipe, you can use these all successfully. I could also argue the
resistance would be lower on these terminals as well.
As for the UL Conditions of Use, I'll see what I can do.
