The lateral sliding displacement can be used to fasten the fastening portion at the bottom surface of the sliding cover to the second fastening portion, so that the high-voltage plug is locked in the horizontal and vertical directions, and the sliding cover has stable working support. And lock function to improve the overall operation.

The secondary purpose of this creation is that when the user wants to pull out the high voltage plug from the high voltage socket, it only needs to pull up on the sliding cover to separate the crimping block from the fastening groove of the mounting part, and then shift to the sliding cover. Displace the guiding portion along the rail plate in the opposite direction of the base, so that the high voltage plug is in a pluggable unlocking state, and when the sliding cover is withdrawn, the pushing block can be abutted against the pressing arm of the latching arm to interlock the buckle The upward biasing is disengaged from the second buckle groove of the first fastening portion, and after the high voltage plug is pulled out a distance, the second terminal group can be disengaged from the first terminal group, and the high voltage plug is disconnected from the high voltage socket. After that, the power supply of the second cable is automatically stopped, and the buckle arm is again fastened in the second buckle groove of the first fastening portion to prevent the high voltage plug from being disconnected before power-off or disconnected during power-on state, thereby ensuring Operational safety.
