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.
