Posted: Sun Jan 20, 2008 7:01 pm Post subject: Infinity Stick connector?

I chose to install my Infinity sticks on my Cozy so that they were 

not hard-wired into the plane, but "plugged into" the plane via 

24-pin Molex connectors through the instrument panel bulkhead. That 

way, if the sticks ever needed servicing, they can be completely 

removed from the plane by detaching the plug.



I should have kept it simple - I have discovered intermittent 

connections, which I've narrowed down to the Molex connectors. By 

joggling them about I can make or break circuits. It's time to dump 

these sloppy plastic connectors and go with something more robust.



I've searched Digikey's catalogue but they offer such a dizzying 

array of "through bulkhead" circular connectors of 17+ wire cables, 

I'm confused about what to select. Without eyeballing each one I'm 

sure to order something that won't work.



I need a twist-on or bayonet M-to-F connector, through-bulkhead, 17+ 

pins, solder or crimp, large enough to accept the ~1/2" diameter blue 

cable that come with Infinity sticks. Could anyone please propose a 

model number/type of connector that will satisfy this need?



Would D-sub connectors be able to handle the high operating currents 

that the pitch trim and speed brake motors draw?



Many thanks

Neil

Take a look at the wire gauge in the Infifity.  How high do you think the

current can be?

Almost any airworthy connector can take it.



I completely agree with you about the Molex connectors.

They don't seem to wipe well and the crimps from Radio Shack don't 

hold the wire reliably despite using my ProCrimp tool on them.



At the very least solder them after crimping.



Personally, I removed all of the Molex (0.6 and 0.9 sizes) before 200hr

on my airframe.



Cheers,

If one wants quality connectors, take a look a Deutsch. They're distributed 

by Ladd Industries. LADD Industries- Deutsch IPD Electrical Connectors

Used them on a Velocity. Four years and five hindred hours later not a peep 

from the connectors. These are high end products and are not cheap..

However, neither is building an airplane.

There, I fixed that for you.



Truth be told, I'll end up spending much less over 6 years of building 

than most guys spend on golfing, or what my brother spends on smoking.  

Building airplanes gets expensive in the same way they get heavy.  

Adding one more support.  Beefing up a connector just a bit.  Using a 

material that is just a bit stronger.  High end connectors might be 

needed, if you're planning a trip into space or you expect the connector 

to hold the wing on.  Probably not even then.  Makes more economic sense 

to use decent hardware, then support and protect it properly.  The need 

for high-end parts evaporates.



I talk to a lot of fellows that are immediately resistant to the idea of 

building an airplane, because they assume that it is prohibitively 

expensive.  We do our community a disservice if we perpetuate the myth.  

Building an airplane is only expensive if we choose for it to be so.
