Aviation plug is the popular name of electrical connector, also known as aviation connector, aviation electrical connector, because of the initial use in the aviation field and named. Generally used with the aviation socket, is widely used in navigation, aerospace, aviation, national defense, military, nuclear industry, electricity and other fields, shell material often used magnesium aluminum alloy, stainless steel, durable.

In the industry management of our country, the electrical connectors and switches, keyboards and so on are collectively referred to as electrical plug components, and electrical plug components and relays are collectively referred to as electromechanical components. The division of connector product types is somewhat confusing, but technically there are only three basic classifications of connector product categories:
① According to the connection mode: threaded connection, bayonet (fast) connection, card lock connection, push-pull connection, straight plug connection;
② According to shape: round and rectangular (cross section),
③ According to the working frequency: low frequency and high frequency (with 3MHz as the boundary).

The technical parameters of the aviation plug are usually three categories:
①Electrical performance: rated voltage, rated current, contact resistance, voltage resistance and insulation resistance, shielding, rf anti-interference attenuation value
②Mechanical properties: contact number and pinhole, installation and shape, shell material, insulation, contact, mechanical life, etc.
③ Environmental technical performance: working temperature, working height, vibration, impact, constant acceleration, sealing, anti-salt spray, anti-humidity, anti-mould performance, etc.

Aeronautical pins are electromechanical components that connect electrical circuits. Therefore, the electrical parameters of the aviation plug itself are the first problem to be considered when choosing the aviation plug. Correct selection and use of aviation plug is an important aspect to ensure circuit reliability. Widely used in all kinds of electrical lines, plays the role of connecting or disconnecting circuits.
