Crimp terminal options

Iím looking for suggestions on what crimp terminals to use to connect 3 wires. I have 5 cabin lights that are daisy chained together so I need to connect 3 wires. Iím using 3M heat shrink terminals for everything else but am not seeing a way to crimp 3 wires together. What would you suggest?

Re: Crimp terminal options

I like to go this route if there is a cabinet nearby where it can be hidden. You can either put two ring connectors under one lug or put in a little jumper clip so each wire is under its own lug.

Re: Crimp terminal options

Thanks Bljones - I have no idea how I missed those but they should work perfect.

erps - Unfortunately I have no where to hide any terminal blocks, the wiring is all run inside the headliner and comes out a 1/4" hole at each surface mount light.

Re: Crimp terminal options

I have used the 3 way connectors that were linked to - and hate them. if you heatshrink the individual connectors the center is hot or exposed. Heatshrink large enough to cover the whole connector doesn't become small enough to seal the 2 wire entrances.

If you cannot use a terminal block get a step down butt connector and put 2 wires in the large side and 1 in the other. Compact and easier to heatshrink.

As it states here
Amazon.com: IMPERIAL 71889 HEAT SHRINK STEP DOWN BUTT CONNECTOR BLUE W/RED(PACK OF 25): Automotive Amazon.com: IMPERIAL 71889 HEAT SHRINK STEP DOWN BUTT CONNECTOR BLUE W/RED(PACK OF 25): Automotive


they are the perfect solution for exactly your situation.

Re: Crimp terminal options

Thanks mitiempo - I had never seen a step down butt connector. This is the route I will go.

Personally, I am not a fan of trying to heatshrink connectors in enclosed cramped quarters near fabrics or finished surfaces- I am too clumsy, or, as pointed out, some connectors aren't heatshrink friendly. That's why I like this stuff:

Liquid Electrical Tape & Spray Electrical Insulation Ė Plasti Dip

Re: Crimp terminal options

I do it almost every day. Low setting possibly or just be careful - don't point it at the same background area for too long. I have never had a problem. I use an electric heat gun, never a torch.

Or you could use coldshrink.

Oh, and it is well past 5 o'clock on the coast you are on.

Re: Crimp terminal options

bl-
Liquid Lectric works very nicely, if you build up some coats. Of course you can use butyl or silicone tape, either self-seals and requires no heat or drying time.

There are also heat shrink guns with heat shields that wrap behind the tube, to reflect heat back. And anyplace that sells plumbing supplies should sell handy heat shields (they used to be asbestos) that you stick behind a copper pipe before torch soldering in the walls.

Or, you do osmething ugly, just use a good crimp terminal and shoot in some silicone grease before you make the crimp. I know, that's illegal in some views of the universe, but it seems to work Real Damn Well.
