hi all,

  seems that my inquiry was misleading. simply  i am looking for the smallest connector i can find that will mount in my panel  and deliver a ground and 12 volt pos. to the appropiate plug in. this will avoid  frequent plugging and unplugging at the gps

  sorry for any confusion.

Hi Bob,



I'd just wander into the nearest Radio Shack & pick up a mating 

miniature phone plug & jack. They look like the connector on headphones 

for iPods & other mp3 players, but you can get them with just tip & 

barrel (2 conductors), instead of tip, ring & barrel. Use the tip as 

positive & the barrel as ground. Jack goes in the panel (obviously) & 

plug goes on the end of your power cable to the gps. They come in 

several different diameters; I'd pick one that does *not* match your 

iPod's audio connector. Go smaller with the gps connector, if you can 

find one.  That will avoid the danger of plugging an iPod's audio output 

into 12VDC power. Or, hide the power jack under/behind the panel so that 

passengers will be unlikely to find it.



The snap-action of the detent in the tip of the plug will keep it 

plugged in unless you pull it out. In my not-so-humble opinion, a 

locking connector in this type application just leads to damaged 

connectors & wiring, while the spring loaded connector will just unplug 

if you snag the wire, & you can plug it back in instead of repairing it 

(at the end of the flight).



There are dozens of other small connectors available, but most either 

lock in place or have no practical holding system, like the typical 

coaxial barrel connectors for power found on cordless phones, etc. If 

you can live with the lack of any latching feature, the coaxial barrel 

connectors are the best bet to help insure that nothing else will fit 

the jack.



If the iPod/power connector issue worries you, you could actually use an 

RJ-11 telephone plug & jack but they require somewhat more specialized 

tools than a soldering iron & solder. And since they lock, there's the 

danger of damage if you snag the wire with something.

I forgot the most obvious answer, the one I used for my gps: just buy 

the mating cable for the gps & hard-wire it into the a/c's electrical 

system, with a short pigtail through the panel at the gps mounting 

location. Drill your hole, add a bushing, & poke the connectorless end 

of the cable through the hole prior to routing to power & ground.

   There are some additional options to consider for hand-held

   power connections in the cockpit. See:

The RS274-010/RS274-013 combination look like they would make for a 

decent firewall pass-through.  I'm sure the case is cheap pot metal, but 

it still has to be a far cry above the typical plastic units.  Protect 

it from direct flames with a stainless steel panel, and I bet this would 

perform just fine.

Bob:

  

 My experience is the smallest connectors are ones  used in RC aircraft and car models.  They are sort of a mini Molex  connector.  I was able to obtain then at a local hobby shop.

  

 Hope this helps.

   Are those the 0.1" spaced devices typical of that which

   is supplied with servos? Those are used heavily in the

   computer industry and are very useful assembly and

   maintenance disconnects. I'd be wary of using them as

   a service connection that sees a lot of mate/de-mate

   also subject to having their companion wires tugged

   on.



   Devices typical of this service are:



http://www.molex.com/catalog/pdf/MX70545.pdf



http://www.molex.com/pdm_docs/sd/901560150_sd.pdf



   I use a lot of these in my designs INTERNAL to

   finished product but wouldn't recommend them

   for the wild and wooly world of the airplane

   cockpit.

   I really thought about adding these to the options

   cited on my website but I've had too many problems

   with general robustness. They're fine for hooking

   wall-warts to your consumer product electro-whizzies

   but I think a builder would become dissatisfied with

   the choice some time in the future.



   Good wire support and engagement retention are

   useful in this application. This is my major complaint

   about the legacy cigar lighter connectors used on

   many automotive accessories. I'm always giving

   the connector to my GPS a bit of a push to make

   sure it's fully engaged after a few hours of

   driving.
