Default How to solder ground wire to RCA Jack

Hi,

please can you tell me where and how to solder the ground shield and one of the internal wire of a balanced shielded interconnect cable to the ground connection of a Cardas RCA male jack (see attached picture)?


Thank you a lot

Renato

I think you're a bit confused - an RCA connector is not balanced, it's designed for single-ended signals. If you connect either of the two inner conductors of a balanced signal to the outside shell, you've just unbalanced the whole thing in a rather poor fashion.

If you have a truly balanced signal, with a shield, you need to use something designed for that, with two signal pins and a grounded shell.

my problem is that I do not know "where" to solder the ground wire on the RCA jack. I tried to solder with the wire passing through the fissure present on the jack, but then I cannot screw the RCA cap (I apologize for my terrible English).

What I would like to build is a single ended interconnect according to the suggestions of Van der Hul cable builders (I also found this proposal somewhere else). Indeed he suggests to use a balanced cable even for a single ended connection. The two internal wires are devoted one for the signal and one for the ground. The shield shoul be connected to the RCA ground just on the source side, while it should be insulated on the amp side.

Ok, I understand. The picture is sort of from the wrong view, but it looks like the shell/shield is the cylindrical part with the cut-out. Solder the shield and one wire to it and the other (signal) wire to the center pin (I can't see it in pic, but it's there somewhere).

On the amp end, just solder the one ground wire to the same shield ring and cut the cable shield back so it doesn't contact the metal. A bit of heat-shrink over the cut end of the shield would ensure that doesn't come in contact with the connector shell.

You can solder on either side of the ground jacket.

if you solder your ground on the inside, i wouls suggest some hot glue to secure the connection, this way if you have to move it in any way, your connection is solid! Just check before use of the glue, there is no real way to clean it again. Best of luck. Mav

Is it really supposed to be soldered
Looks more like the shield is supposed to be screwed together while assembling

Theres an open slit at top
Maybe the shield goes in there

Before soldering the positive lead in the middle, put a small piece of plastic isolation onto the lead, maybe heat shrink tubing
Push it up while soldering, and push it down when done

Always handle the finished cable very carefully, no pulling, no bending, dont ever turn it while connecting, etc

Exchange it for a nice Neutrik instead?

Well, that one you pictured solders like a PL-259 RF connector... you trim and tin the centre conductor and shield, insert, then solder through the slot.

Cheers!
