In recent years, my country's aerospace industry has achieved leapfrog development and achieved many outstanding achievements. These achievements have not only amazed the world, but also attracted a large number of aerospace fans. Now, aerospace fans look over here! "Knowing", do you know the relevant knowledge and testing methods of aviation wiring harness?

Do aviation harness plugs have male and female?

The plug of the aerospace harness is divided into male and female. The specific identification method is as follows:

1. One side of the plug (protruding connector) is male, and the other side of the jack (recessed connector) is female.

2. Distinguish from the appearance and shape, the pointed part of the head is generally a male terminal, and the head with a round hole is generally a female terminal.

3. It can be distinguished by size: generally the larger head is the female head, and the smaller head is the male head.

How to wire the aviation harness plug?

1. In general, there will be a semi-circular splint on the back of the conventional aviation plug to fix the lead, and there will also be two small turnbuckles on it. You can use a tool to remove the nut and then separate the deck.

2. After removing the aviation plug splint, find a thin nail as a tool and put it into the jack to fix it, and rotate the aviation plug in the opposite direction on one side, so that the core and wire of the aviation plug can be naturally pulled out from the front.

What are the connection methods of aviation harness plugs?

The plug is also called a free end aviation plug, and the socket is also called a fixed aviation plug. There are four main types of connections on the market:

1. Plug-in connection: Simply put, the aviation plug and the aviation socket move in a straight cable whether they are plugged in or pulled out, and do not require any rotational operation;

2. Threaded connection: This is a more common type, because this connection method has better fixation and can be used in a strong vibration environment, providing a safe guarantee for the use of the product;

3. Cabinet connection: It can make the equipment exquisite, and it is also easier to maintain and upgrade. Generally, a floating or elastic contact design structure is used to ensure its correct connection;

4. Bayonet connection: As the name suggests, the bayonet fits together. The aviation plug of this type of connection has the characteristics of rapid installation, which greatly reduces the connection time of the aviation plug.

What are the test contents for aviation wiring harnesses?

When conducting aviation wiring harness testing, we mainly conduct the following wiring harness tests:

1. On-off test

2. Withstand voltage test

3. Insulation resistance test

4. Two-wire/four-wire resistance test
