[0002] Aviation plug is a kind of connector, originated from the military industry, referred to as aviation plug. Aviation plug, also known as plug socket, is the most basic component in the aerospace industry. At present, aviation plug is mainly welded by manpower and widely used in various electrical circuits to connect or disconnect circuits.
