This component, together with the docking structure 5, can enhance the dustproof effect at the opening of the socket 3. At the same time, an installation port 12 for installing a status indicator light 11 is opened on the outer surface of the charging gun 1. When the charging head 2 on the charging gun 1 is inserted into the socket 3, it will push the triangular folding pieces 132 to fold into the socket 3. Simultaneously, the status indicator light 11 will light up a solid blue light. During charging, the green light will flash dynamically according to the current. When the power reaches 90%, the green light will remain solid. When fully charged, the red light will remain solid. If faults such as over-temperature or over-voltage are detected, the red light will flash rapidly and trigger an in-vehicle warning simultaneously. After the charging gun is unplugged, the triangular folding pieces 132 will reset and block the opening of the socket 3. At the same time, all lights will be turned off.

[0061] Compared with related technologies, the car charging interface connector with status indicator light provided by this utility model has the following advantages:

[0062] To facilitate real-time display of charging status on the car charging interface connector and improve the dustproof effect of the socket, a dustproof component 13 consisting of an installation ring 131 and multiple triangular folding pieces 132 is installed at one end of the socket 3 opening. This, combined with the docking structure 5, enhances the dustproof effect at the socket 3 opening. Simultaneously, an installation port 12 for mounting a status indicator light 11 is provided on the outer surface of the charging gun 1. When the charging head 2 on the charging gun 1 is inserted into the socket 3, it pushes the triangular folding pieces 132 to fold inwards, simultaneously illuminating the status indicator light 11 with a constant blue light. During charging, the green light dynamically flashes according to the current. Once the charge reaches 90%, the status indicator light... The green light remains constantly lit, and the red light remains constantly lit when fully charged. If overheating or overvoltage faults are detected, the red light flashes rapidly and triggers an in-vehicle alert simultaneously. After charging is complete and the charging gun is unplugged, the triangular folding piece 132 resets, blocking the opening of the socket 3 and turning off all lights. The supplementary lighting component 14 installed on the outer surface of the socket 3 can be lit in low light conditions to assist the user in inserting the charging head 2 into the socket 3. This design improves the dustproof effect of the opening of the socket 3, allows the charging status to be determined by the different colors of the status indicator light 11, and improves the convenience of charging for users by assisting with operation in low light conditions.
