Dumb question - How to use Vampire C7X/CB RCAs?
« on: 1 Jul 2007, 04:20 pm »
Hi people more technically adept than I,
I've made just a few prs of DIY ICs and am very pleased with the results so far. Hoping to take it up a notch, I ordered the aforementioned RCAs. But it's not clear to me how to connect the negative leads and/or the shield (haven't decided shielded or unshielded yet).
I don't know the official terms for the parts so see picture:



There could be a few places to connect the ground/shield - stuffed between the polymer insulator and the negative contact (on the left), or between the outside of the negative contact and the body.  Or do you use the strain relief ring, compressing the leads between it and the insulator?

The description from the Vampire site "Uses compression to insure proper RF shielding and strain relief" makes it seem like it's a solderless conection.

Is it important to have the negative lead touch the negative contact or OK to use the body to make this connection? I guess the body will be in the circuit in either case so I don't know.

Or as per a poster on AA, chuck the barrel and strain relief ring and just use shrink wrap around the neg contact.

Any advice welcome, Thanks!

Those are interesting plugs! 

Sorry though, I have no experience with such things.  I just though I would bump this up to the top.

Never used that plug, but I always use similar plugs. This type of plug is best with a cable that has a robust braided shield ( all the co-ax that I use have robust braided shields ) The center conductor is soldered and the braided shield is fanned out around the circumference of the plug and uses compression to make the connect. I think that connector to connector resistance and percentage of shielding are the two most important things in interconnect cables.
