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:
Electrical performance: rated voltage, rated current, contact resistance, voltage resistance and insulation resistance, shielding, rf anti-interference attenuation value
(2) Mechanical 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.
Aviation plug can also be called plug seat, widely used in all kinds of electrical lines, plays the role of connecting or disconnecting circuits. Improving the reliability of aviation plugs is first and foremost the responsibility of the manufacturer. However, due to the variety of aviation plug, a wide range of applications, therefore, the correct choice of aviation plug is also an important aspect to improve the reliability of aviation plug. Only through the joint efforts of both manufacturers and users can the aviation plug be fully functional.
Aviation plugs are classified in different ways. According to frequency points, there are high frequency aviation plug and low frequency aviation plug; According to appearance cent has circular connector, according to use cent: cabinet uses aviation plug, sound equipment uses aviation plug, power supply aviation plug, special use aviation plug and so on.
