I haven't handled this prior to being asked to find where to get them. I don't think the metal parts are stripped solid wire because the other end of the cable looks to be a standard Cat-5 RJ45 terminator. I think those metal prongs are way too thick and sturdy to be crimped.
The bare probes fit in to a terminal block that looks a bit like a Wago connector. The female end is kind of long like that and has a lever to release the wires, if I recall correctly. These probes are used to program LED drivers. So, they get used hundreds of times per day. We would like to be able to build our own as needed.
