[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors. Its function is very simple. It builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. Connectors are indispensable components in electronic devices. If you observe along the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc.

[0003] In order to prevent the existing connector from falling off after connecting with the external connector, a locking structure is provided on the connector. However, in some specific usage environments, after the lock is locked, the lock will be opened due to long-term external vibration, and then the connector connection will fall off. Therefore, the existing locking structure cannot adapt to more usage scenarios. In addition, during the process of connecting the connector terminals with the external connector, the terminals inside the connector will be subjected to the backward plugging force of the external connector. After multiple plugging, the terminals will slide backward, thereby affecting the service life of the connector. Therefore, it is necessary to further improve the existing connector structure.
