Q: inexpensive HV connector

I used to use BNCs at 12KV when I was a kid, playing with flashtubes and such. It would be interesting to test them to breakdown.

Or use a nylon shell 3-pin AMP or Molex thing, the kind where you insert the pins, and leave the middle one unpopulated.

Somebody does make plastic HV connectors, can't recall the name.

There is an "N" type connector with an extended insulation that has a high voltage rating. Off hand, I don't know what the current rating would be.

King's ?

Those are hideous. SHV is much more reasonable for only 3 KV. Thay are reasonably available.

Fully agree. Just setting the record straight about what to call them.

I've used C as HV connectors, when I wanted a bit of current capability (VHF transmitter using EIMAC tubes).

Those sorts of things are very cheap and would be OK at a few KV if you skip some pins to keep the clearances up. You might prowl Digikey for something suitable.

BNC connectors seem to be expensive; i need to use 140 of them. What is the name / reference / part number of that 3-pin connector?

N and BNC HV connectors can take tens of KV but are VERY expensive..

These are well known; excellent - but too $$$.

Yup! In my use, i could get away with using those DC power connectors (like what is used in wall warts).. Looking for a lower cost connector.

PL-259/SO-239 was my first thought, but A HUNDRED AND FORTY OF THEM on ONE BOARD?????? (same reaction for N) =:-O

Maybe you could get something like a teflon TNC or something.

Good Luck! Rich

That one popped into mind because of the co-axial nature of the WW plug. How about this one...

What kind of connectors do they use in laser printers? Don't those make about 5 kV on the power supply board and have to transport it to the, umm, senior moment alert, you know, the surface that gets exposed to light and then the toner sticks to it? Anyway, whatever connector they use has to be pretty cheap given the pricing on laser printers.

Yeah; i thought of the KK series..except no nice way to make female end look decent and safe. Max use: 3KV, 0.5mA.

Hmm...not too bad. Will consider those. Thanks.

Teflon anything is expensive, and TNC is not conducive to production use.

Maybe... Thanks.

There are *tons* of (R)TNCs being used every day.
