An HVDC supply is supposed to have a bleed down resistor in it. Breakdown of such a device as a connector usually comes down to exposed bare node separation distance and their shape. A sharp point will arc 'faster'. We used old 50 Ohm CB radio coax and connectors on some of our HV designs. The coax has a very high rating and the connector nodes are farther apart then on miniature connectors. (of course). We had a design where the ouput was about 5 inches deep in the chassis. We used a non-conductive paste and a 5 inch exposed center and sheath of an rf coax cable. So the 50 ohm connector attached to the coax braided shield, and the ceneter "stab" stuck out from that the required 4 point whatever inches to make it hit the HV node down the PVC tube on the HVPS. It makes for a 'handling safe while energized supply' with the live end of the cable becoming the safety zone.

Build a coin shrinker... charge up that bank, and discharge that through yourself instead of the coil. You'd shrink alright.
