Does anyone have a favorite high-current PCB connector?
 
I'd like to get 20 wires into a pluggable connector, to go on a module
like this:

We need at least 7 amps per contact.
 
That litle green Phoenix connector is cool. Wires screw into it
without tooling, and it's easy to mate and unmate. But it's only 5
pins.
 
I was planning to use four of them, with two on a baby board, but that
idea wasn't popular.

Nice device, as I understand it what it does is if your cables are too
good it randomly makes some of them faulty, and then the user has to
figure out which one of them it is. Makes life more interesting!

The idea is to simulate what a cable fault between two boxes would do
on an aircraft. This is also called a guillotine box.

Our customer used to make what they call a FITS box to do this, but it
wasn't very reliable and has got hard to make. So we did a version. It
has polyfuses to help protect the relays. We added voltage and current
measurement and BIST, built-in self test.

It can be used to snoop voltages and currents in a cable too.

The board is HEAVY.
