Default Umbilical Connector Suggestions

Hey guys,

I need some advice:

I am building the final form of my pre-amp, which will have two chassis, PS and Pre. I will need to run two umbilicals between the chassis (HV and grounds, and AC). One will need to 6 connections, while the ther will need four. The HV will be at approx 330VDC 45mA, and the AC will be 12.6VAC 1A.

I would like to hear what you suggest for the connectors of the umbilicals.

Thanks,

Bryan

For my preamp, I use braided cable and octal sockets/plugs. Works great.

The ancient Jones cinch style connectors are still being made and don't cost that much for 6 or 10 positions.

Or you could always go with the metal mil spec Amphenol connectors but they are around $12 each for a 6 pin. We use them a lot at work and they are almost indestructable.

There is no such thing as a final form! Go for a connector with more pins than you need at the moment - it will save tears later on. Or you could use them as extra earth connections to get the earth resistance down.

One more point- for safety reasons, use a male on the preamp chassis, a female on the PS chassis. That way, no matter whether the cable is plugged in or not, no HV points are exposed for easy, inadvertent touching.

Thanks Tall Shadow,

I'm glad I'm amusing someone besides myself.
But you probably shouldn't encourage me

Uh oh... I see SY has changed his avatar again.
Looks like I got his Gort!

Har!

Best,

Just having a little fun. I'm always interested to see who can identify which avatar. Gort was easy. The one before that, no one got (still one stubborn guy guessing so I can't give it away). The one before that, only the Dutch and Belgian guys recognized- the late Pim Fortuyn.

Back on topic, I saw some socket/plug combos that looked exactly like octals, but had 11 pins. That tempts me into an upgrade...

But can you identify the quote I made in reply?

Terman?

Looks like one of those old electronics pioneers.
