I have no experience of coax connectors - there's the cheap and

connector must be comfortable at 500v, but the other requirement would
be that the cable connector - presumably female - should be
sufficiently shrouded that it's very hard to touch since there's over
400vDC on it!!

Best choice here?

If you want posh go for Lemo. They make co-ax connectors suitable for
high power transmitters where I'd guess there are a fair few volts
flying around. But be prepared to dig deep...

I'd agree with the above since IIRC Lemo make designs specifically for high
voltage uses, and they can provide self-locking. That, combined with being
totally incompatable with the usual audio plugs would help avoid accidents.
You will, of course, have to also choose a cable that is designed for high
DC voltages.

Lemo do tend to be expensive - but cheap if they save your life.

Slainte,

Jim
