The lock is provided with a lock slot, and the lock is equipped with a handle. When the connector plug is inserted After the connector socket, toggle the handle to insert the locking slot into the locking pins on both sides of the upper part of the connector plug housing, and lock the connector plug on the connector socket. It will not loosen during the charging process of the vehicle.

working principle

When the electric vehicle battery connector socket is used in conjunction with the electric vehicle battery connector plug, the electric vehicle battery connector socket is installed and fixed on the battery pack through the socket mounting plate, and the positive and negative power sockets are respectively connected to the positive and negative poles of the battery pack through wires. Connected well, the signal communication sockets are respectively connected to the battery pack signal acquisition end, and then the electric vehicle battery connector plug is inserted into the connector socket, so that the power plug, that is, the metal terminal (male pin) and the power socket (female pin) are closely mated. At the same time, the signal communication plug in the electric vehicle battery connector plug is closely mated with the signal communication socket in the electric vehicle battery connector socket. Turn the handle of the buckle and insert the card slot of the lock into the connector plug shell Lock the electric vehicle battery connector plug on the upper part of the electric vehicle battery connector socket on the locking pins on both sides of the upper part of the body. The power line and the signal communication line installed on the connector plug are respectively connected with the vehicle control power line and the signal control line.

In the vehicle control, after the control key is turned on, the battery pack is given a 12V DC voltage through the signal communication plug No. 1 and No. 2 in the signal communication line, so that the high-voltage relay inside the battery is closed, and the battery pack passes through the positive and negative power plugs. Output high-voltage electricity, and the No. 3 and No. 5 signal communication plugs in the signal communication line will output CAN signals to the vehicle in real time after the No. 1 and No. 2 signal communication plugs are connected, and upload the battery pack information.
