Description

Technical Field

[0001] The utility model relates to the field of connectors, and in particular to a connector assembly that takes both locking degree and convenience into consideration. Background Art

[0002] A connector is a commonly used component in electrical engineering. Its function is to connect circuits on different devices or different modules in a circuit, so that current or signals can flow or transmit, and the circuit can achieve a predetermined function. Existing connectors include connecting plugs and connecting sockets. The connection method is usually to insert the connecting plug into the connecting socket, and the conductive terminals of the connecting plug and the conductive terminals of the connecting socket are electrically connected.

[0003] When the connector does not need to be connected, a cover needs to be arranged for the connector to protect the conductive terminals in the connector. Since the connecting plug and the connecting socket are selectively arranged with locks, the locks are prone to mismatch or conflict when the cover is connected to the connecting plug or the connecting socket, thereby affecting the assembly adaptability of the cover. While providing a stable and strong locking force for the connector, it is also necessary to design a relatively convenient locking or unlocking structure for the connector. Utility Model Content
