Mark/Foggy Posted December 31, 2010 Report Share Posted December 31, 2010 Right, what I'm after is a Jack Plug used in the old Bakerlite days of telephony. Looks like a standard 8mm Guitar/Amp Jack Plug but carries 4 Poles (I think), need the male. Anybody got any ideas? Ta Link to comment Share on other sites More sharing options...
kaighn80 Posted December 31, 2010 Report Share Posted December 31, 2010 maplins or egay would be my best guess, might have to look further abroad on egay though like egay.us Link to comment Share on other sites More sharing options...

control_67 Posted December 31, 2010 Report Share Posted December 31, 2010 So you want a TRRS 1/4" (6.35mm) male jack? or do you need 8mm? Link to comment Share on other sites More sharing options...
Mark/Foggy Posted December 31, 2010 Author Report Share Posted December 31, 2010 So you want a TRRS 1/4" (6.35mm) male jack? or do you need 8mm? Yeah my bad must be 1/4", whats TRRS? bet you can't guess what it's doing on a bike either! Link to comment Share on other sites More sharing options...
control_67 Posted December 31, 2010 Report Share Posted December 31, 2010 Had a look and there's loads of 3.5mm TRRS jacks available but sod all in 1/4". TRS is easy to find but that's probably no use. What's the application? Link to comment Share on other sites More sharing options...

TRS is easy to find but that's probably no use. What's the application? Believe it or not it feeds this Earth, 2 independent switched lighting circuits and a constant live feed. Endurance minimum rear lighting spec, but QD so that the seat and subframe come off as one in a crash. The female jack is mounted to the chassis.

TRRS is Tip Ring Ring Sleeve, This site has a good guide Not easy to find however. If you could use a 3.5mm it would weigh less and be easier to source.

control_67 Posted December 31, 2010 Report Share Posted December 31, 2010 So ideally you want something light and easily replaced if it breaks? You could use 2 TRS jacks to accomplish the same thing, advantage being that they are easy to find pretty much anywhere that sells electronics. I'd guess that a 3.5mm wouldn't be able to handle the gauge of cable you'd need to use for a lighting circuit unless you were using LEDs Link to comment Share on other sites More sharing options...

The team's moved on plenty since those days, but authenticity is needed. Link to comment Share on other sites More sharing options...
control_67 Posted December 31, 2010 Report Share Posted December 31, 2010 you could contact Switchcraft or Neutrik and see if they can custom make one for you or maybe do them on special order. Just be aware that some Military spec jacks have slightly different dimensions. Your best bet is to try a guitar lead and if it goes in smoothly and latches then you have standard 1/4" dimensions.

lorenzo Posted December 31, 2010 Report Share Posted December 31, 2010 When you say old style telephony style thing, are you meaning that it's shaped slightly differently to a guitar type jack, a bit more rounded at the end like this? Also, why the need for 2 seperate circuits and hence the 4 contacts? If you've got a common live going to it then surely all you want is a switched earth for your 2 lighting circuits?

Hmm optical fibre , wonder how soon we'll be working that into race bikes. Might not be as crash friendly as a ring earth loom, but it would look cool. I might have to start looking for redundant telephony forums out there in the clockwork universe and see if there are any friendly dinosaurs willing to donate to the cause.

If you find it's a bantam and you want one of those I might be able to see what I can find at work. I don't nick biros and staplers etc, so it's about time I balanced things out.
