In addition to meeting the general performance requirements of the electrical connector, a particularly important requirement is that the electrical connector must achieve good contact, reliable work, and convenient maintenance. The reliability of its work directly affects the normal operation of the aircraft circuit and involves the safety of the entire host.
For this reason, the host circuit has very strict requirements on the quality and reliability of the electrical connector. It is also because of the high quality and high reliability of the electrical connector that it is also widely used in military systems such as aviation, aerospace, and national defense. Commonly used classification methods for electrical connectors include shape, structure, and purpose.
