What is push-pull self-locking connector? Circular push-pull connector connection modes, circular push-pull connector in measurement and test application

Circular push-pull connectors play an important role in the construction of electronic engineering, ensuring smooth circuits, so they are widely used. At present, there are many types of circular push-pull self-locking connectors on the market, with various specifications and styles, as well as many excellent connection technologies. At present, there are four connection methods that are more commonly used. Let’s introduce the specific content below.

1. threaded connection

   A connection form often adopted by circular push-pull self-locking connectors that have larger size contacts and work in a strong vibration environment. This type of connection can be fitted with a fuse to prevent loosening after the connection is completed. This connection form is reliable, but the connection and unloading speed is slow.

2. bayonet connection method

  It is a reliable and rapid connection and separation form. Most of the circular push-pull self-locking connectors of the card 121 connection form have a visual display of correct connection and locking, which can be observed from the small hole on the side of the connecting nut of the circular push-pull self-locking connector.

3. plug connection

   It is a multi-purpose connection form. When the plug and socket of the connector are connected and disconnected, their moving direction is usually a reciprocating linear motion, without twisting and rotating, and only a small working space is needed to complete the connection and unloading. The common plug connection has two structures: ball or pin. Because this connection form does not have a mechanically labor-saving mechanism, once it is inserted incorrectly, the mechanical resistance will increase significantly, and it can be discovered in time.

4. cabinet connection method

  It is a circular push-pull self-locking connector(which is also a metal connector) used on some equipment that needs to be blindly connected near the frame, which can make electrical equipment lighter and smaller, easier to maintain and more reliable. This type of connection prevents the operator from feeling the connection, and a precise positioning device must be designed to avoid forcibly connecting the wrongly inserted circular push-pull connectors, making it impossible to insert the wrong connector. The cabinet-type circular push-pull self-locking connector usually adopts a floating or elastic contact design structure to ensure its correct connection.
