Default Electrical Connector Wing to Body

Did anybody use an electrical connector on the outside of the fuselage, at the wing root, and within the wing connection space to connect wires from the wing to the fuselage? If so was there plenty of room for the connector? Has weather worn on the connection?

I put pig tails on my wings with round CPC connectors from Jameco and I don't want to drill a hole in the fuselage for them to fit thru. I could put the connector on the wing wires after pushing them thru a small hole into the fuselage, but if I mount a connector on outside of fuselage just behind the spar it would be an easy connection later to put the wings on. And later if the wires need service I could just remove the wing root fairing.

Is this a bad idea? What have others done for bring wing wires into the fuselage?

I did on several RVs with no regrets and would do it again as it's a no brainer and very convenient. I wouldn't use huge connectors as the gap isn't all that big. Water doesn't seem to have been an issue either. Each item in the wing had it's own connector and the inspection loop was left plenty long enough to connect the wires above wing.

Instead of connectors outside the fuselage I put terminal blocks on the floor underneath the seat pans. If the wires ever need replacing I can easily disconnect them at the terminal block and either pull the small ring terminal through the side hole or cut the ring off and pull the wire through. No outside connections to worry about getting to this way.

Like Steve says, this is by far the easiest method. It is VERY rare to need to remove the wings later and even if you did, the seat pans would have to come off to access the mounting bolts.

Would love to see some photos!

I'm using Deutsch DT/DTM environmentally-sealed, high grade automotive connectors for this connection. Easy to assemble and robust.

Got mine at: http://www.deutschconnector.com/prod...es_connectors/
though they are generally available from many sources.

.. no photos yet; still wiring up the roots!

Default Wing connectors

Bill
Where do you plan to put the connectors? If inside the fuselage how will you get them in there? Will you drill a fairly large hole? Or put connector bodies on after running wires inside?

PS I looked at the terminal block but I don't like the exposed wire ends. Most are positive current.

If someone wants to go this direction, go to your Caterpillar dealer and look at their DT kit. It has a assorted connectors and the crimping tool for basically the price of the crimper. A pretty good deal if you want to go this direction. The DT is a very good reliable all weather connector.

Same here, easy access, secure, reliable, higher current capacity and cheaper.

As an alternative, put a small service loop in the wing root area. If you ever have to remove the wings you can then add a connector.
