Four common ways to connect aviation plug connectors

Aviation plugs play an important role in electronic engineering construction to ensure smooth circuits, so they are widely used. There are many types of aviation plugs on the market, with various specifications and styles, as well as many excellent connection technologies. Currently, there are four commonly used connection methods.
1. Threaded connection method is
a connection form often used by aviation plugs with larger-sized contacts and working in strong vibration environments. This type of connection can be installed with a fuse to prevent loosening after the connection is completed. This connection form is reliable in use, but the connection and unloading speed is slow.
2. The bayonet connection method
is a reliable and rapid form of connection and separation. Most card 121 connection style aviation plugs have a visual display of correct connection and locking, which can be viewed through the small hole on the side of the aviation plug connection nut.
3. The plug-in connection method
is a multi-purpose connection form. When the plug and socket of the aviation plug are connected and disconnected, the moving direction is usually a reciprocating linear motion. There is no need to twist or rotate, and only a small working space is required to complete the connection and disassembly. Common plug-in connections have two structures: ball or pin. Since this connection form does not have a mechanically labor-saving mechanism, once it is mis-inserted, the mechanical resistance will increase significantly and can be detected in time.
4. The cabinet connection method
is an aviation plug used on some equipment that is close to the frame and needs to be blindly connected. It can make the electrical equipment lighter and smaller, easier to maintain and more reliable. This type of connection prevents the operator from feeling the connection. An accurate positioning device must be designed to avoid forcibly connecting misinserted aviation plugs together, making misinsertion impossible. Cabinet-type aviation plugs usually adopt floating or elastic contact design structures to ensure their correct connection.
