Looking for a specific type of PCB mounted Kelvin test post

Question

I don't even know where to start. I've done a cursory search/browse through Digi-Key and Mouser but haven't found anything similar. With words failing me I've drawn up a model of what it is I'm looking for.

In short: I need to design a new test station at work that can take Kelvin measurements and can handle high compliance voltages (around 3 kV).

The test posts are to hold the gold-plated leads of a UUT as it gets cycled through its operating temperatures, so ideally they would also be resistant to thermal changes. I know I've seen something similar before (I think at an antiques shop actually), but I can't for the life of me figure out what to search to find them.

Any leads or help in finding something similar is greatly appreciated.

Answer 1

1. Get a 4-contact, dual-readout, card edge socket
2. Shave off the plastic at the two ends, to allow insertion of a wire
3. Install on a tall, insulated pedestal

Answer 3

Found almost exactly what I was looking for from Loranger. They appear to have quite a few different versions which should work well enough for my application. Thanks again to everyone who gave suggestions

Answer 4

A somewhat simpler solution would be to use pogo pins in a 3D-printed "clamshell" that can be used to latch the UUT lead over a pair (or more!) of linearly arranged pogo pins.

The 3D-printer shell can be mounted to the chassis on ceramic standoffs, since FDM prints aren't exactly known for their low leakage. A resin print may be a better insulator, but you'd have to evaluate that.
