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.
