Four interconnection forms of connectors

Connectors are an indispensable basic element of all electrical systems. As a node, it can transmit current or optical signals between devices, components, equipment, and subsystems independently or together with cables, and maintain no signal distortion and energy loss changes between systems. It is necessary to form a complete system connection. basic element. In the way of realizing interconnection, it has a variety of interconnection methods.

1. Threaded connection, a connection form that is often used in contact pieces with larger sizes and connector pin jacks that work in strong vibration environments. After the connection is completed, a fuse or a nut to prevent loosening can be installed, which is reliable in use, but the unloading speed is slow.

2. The bayonet connection method is a reliable and rapid connection and separation form. Most electrical connectors in the card 121 connection form have a visual indication of proper connection and locking, which can be viewed from the small hole on the side of the electrical connector's connection nut.

3. The plug-in connection method is a multi-purpose connection form. The common plug connection has two structures of ball or pin. Because this connection form has no mechanical labor-saving mechanism, once it is inserted by mistake, the mechanical resistance will increase significantly, and it can be detected in time.

4. The cabinet connection method is used for electrical connectors on some equipment that needs to be blindly connected near the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. Connector pin receptacles usually use a floating or spring contact design structure to ensure their correct connection.
