[sdiy] Connecting two halves of a case...

[James Dunn]

Hi list,

I've been working on a small portable synth which is housed in a flip 
top case (of which both halves contain circuitry) and am a bit stuck on 
how to connect them together. I need to connect wires for ±15V, ground 
and audio out (mono). I could take it outside or inside the case and it 
could be something that I plug in every time I use it or is hard-wired. 
Does anyone know of a good way of doing this? Or even a product that is 
available from some supplier?

thanks

James
