I made similar experience with TRS, kind of non-linear contact resistance.
But applied as a connector for a hi-z input these work fine for my limited resolution equipment (EMU-tracker USB soundcard)

Thanks but what I'm looking for is the male connector that goes to the cable and the particular has the twist lock made of plastic. Good for testing signals with DC offset -this soundcard can handle 400V DC. Even more useful for a DIY tube curve tracer that is designed to work with the oscilloscope. Although it's floating and properly grounded when connected, it's there to bite when you hold it in the air...
Is this aiming to be a project for a one-off build, or are you looking to make this something that will be built and used by a wider community? If you're looking at a wider community I'd suggest to use something a bit more standard aimed at balanced cabling, like an XLR or TRS jack. If these need more space, use a larger box.
Apologies for my misconception, I thought that BNC is the standard and then adapters like these
On the other hand, it's not difficult for me to upload corrected gerber files with all improvements suggested here, but it would be impossible to test them.
