Description

Technical Field

[0001] The utility model relates to the technical field of automobile connectors, in particular to a locking buckle structure of an automobile connector. Background Art

[0002] Automotive connectors are used to transmit current and signals to enable the circuit to achieve the intended function. Locking parts are usually provided between the plug and the connector of the connector to prevent the connector from loosening during operation.

[0003] For example, the locking buckle structure of the automobile connector with the authorization announcement number "CN220456773U" solves the locking buckle structure of the existing automobile connector. It is fastened with screws, and the screws are often lost. The above-mentioned sealing sleeve can press the limit block against the end of the docking seat. In the initial state, the limit block is located in the groove body of the plug rod. After the plug and the connector are docked, the plug rod passes through the socket. At this time, the limit block is rotated so that it contacts the end face of the docking seat, and the sealing sleeve is slid so that the pressing part on the sealing sleeve can press the limit block against the end face of the docking seat. The locking buckle structure of the existing automobile connector inserts the plug rod into the inside of the socket. Considering that the plug rod and the socket also need to be separated, the plug rod does not have any auxiliary extraction components. When the plug rod is inserted into the socket due to external factors such as rust, it cannot be easily pulled out. The plug rod breaks inside the socket when it is pulled out, which increases the difficulty of disassembly. At the same time, the existing plug rod and the socket are used to lock the connector, and the fixing method is single. There is a risk of loosening of the plug rod and the socket, resulting in the risk of loose locking of the connector. Summary of the invention
