 Posted: Sat Oct 03, 2009 8:25 am Post subject: Pitot Wiring Connectors |
 |
|
Curious if anyone had a solution for a connector problem. I sent off my Velocity's sharkfin pitot for plating and when it came back, the two wires to the heating elements were missing. The two wires had female pin connectors which mate to the two male pins of the heating elements. The female connector slides right over the male pins. By memory, the pins are approx. 2-3/32nd inch in diameter and approximately 1/2" long. I've seen similar pins on some other pitots, but have not been able to find the connectors that I can attach termials ends to to hook up to the plane wiring.
Anybody know of a source for female pin connectors that might work?

I've never seen a heated pitot tube that did not mate
the AN3113-1 connector. That doesn't mean that yours is
the same format . . . but I suspect it is.
The AN3115-1 is a pricey dude. ACS get about $60 for
it . . .
http://www.aircraftspruce.com/catalog/inpages/heatedptubes2.php
. . . and offer it under their own part number.
Others on the 'net get as much as $100 for it. I've
contemplated building these and even have a set of
drawings and a slitting saw to do the cross-cuts in
the receptacles. See . . .
http://www.aeroelectric.com/Pictures/Connectors/AN3115_Pitot_Tube_Heater/
I built one set of pins way back when and they
would probably have worked well. After looking
at the hassles of tooling up a housing and considering
just how many connectors I might sell . . . well, let's
just say the blush was off the rose.
If it were my airplane, I would solder pigtails onto
the extended pins and install my own connectors on the
ends of the pigtails. Say "power pole" style connector
like those used on B&C PM alternators?

Bob, I've done a quick search for "power pole". Can you supply a link to a
supplier?

Bob,
Thanks for the link. Yes, it looks like that connector would fit, though it is different than what was on the pitot initiatlly, which worked fine, but was apparently 'home made'. The photos show the original connectors on the old pitot in which the element had gone bad. The connectors just 'pop off'.
The old pitot wassilver-soldered and servicing was 'not possible', but I had the good fortune to find a like Kolhsman pitot on ebay for $15; find of the decade, which I sent off to have plated, but then the connecting wires became lost.
If I'm unable to find the bare connectors, perhaps I'll have to dig down into the green moldy stuff and cough up for the one shown in your link.

Hi Chuck,
I may have a pitot connector that I don't need any longer. It will be
Monday before I can check to see what condition it's in. If it's OK
and will work for you, you are welcome to it.

Hi, bob,
See what you have. I checked Neals suggestion and had seen if in a couple other searches. It appears to be a tension loaded flat blade that is designed to mate up with another flat blade. With both blades tensioned, the pressure is enough to form a good connection between them. A blade to pin connection might work, but that's certainly not the way it was intended.
Let me know and if works, we enter some high level negotiations for it. lol
