1. Threaded connection
This is a connection form that is often used in some larger-sized contacts and connector pin jacks that work in a strong vibration environment. After the connection is completed, a fuse or nut can be installed to prevent loosening. This connection form is reliable to use, but the connection and disconnection speed is relatively slow.
2. Bayonet connection
This is a reliable and fast connection and separation form. Most of the electrical connectors of the card 121 connection form have a visual display of correct connection and locking, which can be observed through the small holes on the side of the connecting nut of the electrical connector.
3. Plug-in connection
This type of connection has multiple uses. When the pin jacks and sockets of the electrical connector are connected and disconnected, their moving direction is generally a reciprocating linear motion, without twisting and rotating, as long as a small working space is used to complete the connection and disconnection. Commonly used plug connection has two structures: ball and pin. Since this connection form does not have a mechanically labor-saving mechanism, if it is inserted incorrectly, the mechanical resistance will be significantly greater, but it can be discovered in time.
4. Connector pin jack cabinet connection mode
This is an electrical connector that is used on some devices that need to be blindly connected to the frame. It can make electrical devices more lightweight and compact, easy to maintain, and more reliable.
This type of connection makes it impossible for the operator to feel the connection. It is required to design a precise positioning device to prevent the pin and socket of the connector from being inserted forcibly, making it impossible to insert it. Connector pin jacks often use floating or elastic contact design structures to ensure their correct connection.
