[0001] The utility model relates to the technical field of connector, especially a self-locking connector. BACKGROUND

[0002] The connector is the key element for connecting two circuits in the electronic equipment, and is an important component of the industrial system. The functional components of the connector mainly include the plug and the socket.

[0003] The existing self-locking connector usually adopts the push-pull locking mechanism. In this mechanism, there is an extensible latch inside the plug. When the plug and the socket are pressed together, the internal latch will retract, allowing the plug to be smoothly inserted into the socket. Once the plug is fully inserted, the latch will automatically pop out and embed into the groove of the socket, thereby realizing the locking. However, if the above-mentioned way is adopted, the user needs to perform the squeezing and pushing actions simultaneously when connecting or disconnecting the connector, and the action will be limited in a narrow space, resulting in inconvenient operation. Meanwhile, in an environment with poor visibility, the user is difficult to accurately align the plug and the socket. SUMMARY
