There are four main types of industrial connectors:

1. Thread connection mode:

Some contacts with large size and electrical connectors working in strong vibration environment often adopt a connection form. This type of connection can be fused to prevent loosening after the connection is completed. This connection mode is reliable, but the connection speed is slow.

2. Bayonet connection mode:

It is a reliable and fast form of connection and separation. Most of the electrical connectors with card 121 connection have the visual display of correct connection and locking, which can be seen from the small hole on the side of the connecting nut of the electrical connector.

3. Plug connection mode:

It's a versatile form of connection. When the plug and socket of the electrical connector are connected and separated, the moving direction is usually reciprocating linear motion, without torsion and rotation, only a small working space is needed to complete the connection and disconnection. The common plug-in connection has two structures: ball type or pin type. Because there is no mechanical labor-saving mechanism in this connection form, once it is inserted by mistake, the mechanical resistance of the special pin row mother manufacturer will increase significantly, which can be found in time.

4. Connection mode of cabinet:

It is a kind of electrical connector, which is used for some equipment close to the frame that needs blind connection. It can make the electrical equipment lighter, smaller, easier to maintain and more reliable. This kind of connection makes the operator not feel the connection, so the positioning device must be designed to avoid forcibly connecting the electrical connectors inserted by mistake. The placement of pins and busbars makes it impossible to insert them by mistake. Cabinet electrical connector usually adopts floating or elastic contact design structure to ensure its correct connection.
