[0008] Preferably, the wire inside the connecting wire is connected to the conductive core.

[0009] Preferably, bolt holes are arranged around the mounting plate, and the mounting plate and the protective ring are made of metal.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model discloses a high-voltage charging self-locking connector for automobiles. When the device is hit by external force, the pre-breaking groove is adopted to disconnect the device, so that the charger can quickly fall off the device, thereby avoiding the fixation of the wires, resulting in damage to the charging gun of the charging equipment and the charger vehicle, thereby effectively reducing the property loss in the event of an accident. At the same time, the metal protection ring is adopted to effectively increase the strength of the device, thereby increasing the service life of the device. The wire fixer is provided to increase the stability of the wiring harness installation, thereby avoiding the problem of the wiring harness falling off after long-term use.
