WIRE SPLICE CONNECTOR AIRCRAFT INSTALL

Electrical connectors are gendered by their pins. No need to worry because it’s quite simple. When someone asks you if you need a male or female, it can often be confusing. One important subject to keep in mind when working with electrical connectors is the gender of the connector. Our focus will be on the most common electrical connectors used in our aircraft by the average builder and pilot. Better connectors have the pin numbers on both the face and the shell side insulator blocks.

Here’s the ubiquitous 25-pin D-sub connector, female variety. Detailed descriptions of each connector and its relative part numbering schema, mil specs and more are available on the web if you desire more information. Because there are literally thousands of connector types, it is impossible to discuss each one in detail.

They can be used to join electrical power wires, signal wires, pitot/static tubing, fluid lines and just about anything else.

Connectors are a way of life, and the few additional ones you might install are a small risk if you know what you’re doing.Ĭonnectors are something that most every homebuilder will deal with at some point in the build project. After all, you must have a certain number of connections, starting at the battery, down through each switch, circuit protection and then to the very device you’re talking about. So while the one-wire rule is theoretically ideal, it is terribly impractical. Fewer connections discourage problems that range from poor mechanical attachment (wire to pin/socket as well as pin to socket), corrosion between pins and sockets, and the potential for getting wires crossed in a connector. Yes, a continuous piece of wire from source to destination is the theoretical ideal. I hear the grumbling from the back of the room already.

They allow an airliner to have a complete engine change done in hours instead of days, and they let us quickly and easily remove things from our airplanes (like wings, lights and avionics) while also making future maintenance easier. Generally, connectors are used more for convenience than necessity. Three rows of pins usually means a high-density D-sub and smaller pins. These four standard-density D-sub connectors-with 9, 15, 25 and 37 circuits-share pin size. I thought I’d start this article out with a fancy definition of what a connector is, but when I looked in the dictionary for a good explanation, I found it simply states a thing that connects! Well, because thats pretty obvious and also not helpful to our discussion, we’ll take a closer look at connectors as they relate to airplanes.
