Posi-Lock Connectors
 

Has anyone used these connectors before? I was doing a search on the word posi and this website was the first one to come up.

I have not used them. Based on a quick review of online information, I do plan to get a few and do some testing. I'd like to understand how the electrical contact is controlled when the parts are assembled, and how sensitive that contact might be on variation in several factors, including the length of conductor exposed when the wire is stripped and the length by which the stripped wire protrudes through the threaded piece just before mating with the central piece. The parameter I'm looking for is electrical resistance. Basically I want to know how much voltage drop and power dissipation one of these will add to a circuit, for a given current.

I'll post results when I find some parts and get time to conduct a few tests.

This product review provides a little more information, and includes some helpful video.

They look pretty neat, although I wouldn't get them for robotics because they look like they're heavier than the standard crimp on connectors we use. The "Water-Tite" ones might work good on our boat trailer, seeing that saltwater loves to eat copper, but I think the crimp and heat shrink ones I got last time will last a long time. Too bad they can't make decently sealed LED lights or step down the current at the tongue of the trailer instead of at the lights themselves (which would help with corrosion for the trailer lights if they get wet). I guess the good thing about the LED lights we have is that they have a lifetime warranty, so every time they break, we just go exchange them :D.
