Using Lever-Nut connectors for super-easy robot wiring?

Because the new Talons and Victors both have in-built wires instead of the screw-on connectors from the old talons, jags, spikes, and old victors, it should be possible to do a fair amount of robot wiring without any soldering at all.

Here's the AM page for the connectors that I'm talking about. http://www.andymark.com/product-p/am-2575.htm

The only concern I have is the current limit- The PDB is rated for 40 amps, but these have a max of 32A at 600V (I don't know enough about electrical stuff to discern whether we're safe because the robot is just at 12V)

Regardless, I think you could do some really, really nice robot wiring with these. I've seen one before, and the hold they have on the wire is about as strong as the jaws on the PDB.

I love the idea of a robot without almost any soldering at all- soldering 20+ electrical connections can be time consuming, and bad solders coming apart in a match are a surefire match-loser. Complete Plug-and-play connections would make wiring super fast and very painless. Plus, it seems that you could buy all the connectors needed for a robot for less than $50, which is a total steal considering how much time they will save during build season.

What do you guys think?

Re: Using Lever-Nut connectors for super-easy robot wiring?

In four years the only soldering we've ever done is on a custom circuit we did in 2012. These levernuts are nice and I have used them for some temporary automotive applications.

With that said, what's wrong with crimp connections? Levernuts will be nicer as they are removeable, but they are also quite larger and more costly.

If you want a good no tool needed wire connector I recommend Posi-Lock http://www.posi-lock.com/posilock.html they aren't cheap but they are very reliable and not much more bulky that the cheapo insulated crimp connectors.

Re: Using Lever-Nut connectors for super-easy robot wiring?

Sgt,
The voltage rating on these connectors are the safe level at which touching the outside of the connector will not result in an arc to your finger. The max current specification is rated for continuous current over a long period. The PD is rated much higher than 40 amps. It is merely the breaker used for the size wire that you may use. #12 wire (minimum size) can be used with a 40 amp breaker.
