Background technique

In production and life, it is often encountered that the two ends of cables and optical fibers need to be connected to each other. Usually, connectors are used to achieve communication. Connectors are mostly composed of plugs and sockets. Plugs are also called free-end connectors. The socket is also called a fixed connector. The connection and disconnection of the circuit is realized by the insertion and separation of the plug and the socket, so various connection methods of the plug and the socket are produced. For circular connectors, there are mainly three methods: threaded connection, bayonet type connection and pin-type connection. Among them, threaded connection is the most common. It has the advantages of simple processing technology, low manufacturing cost, and wide application range. However, the connection speed is slow and it is not suitable for occasions that require frequent plugging and fast connection, and it is impossible to determine whether the socket and plug are inserted. In place, it may be due to the small distance between the male terminal in the plug and the female terminal in the socket, which may cause arcing and short circuit problems.

In addition, the working environment of connectors such as automotive connectors is relatively harsh, and their sealing and waterproof performance needs to be improved. Usually, waterproof rings, blind plugs, etc. are used to achieve waterproof effects. However, different connectors, their The number of terminals to be installed is different, and a waterproof device needs to be configured according to the type of the connector. The production cost is relatively high, and the waterproof performance of the blind plug is not good.
