Abstract
A locking and unlocking structure is used for locking and unlocking a plug and a socket which can be inserted oppositely along the horizontal direction. The lock catch unlocking structure comprises a locking block, a metal elastic piece and a slide rod, wherein the locking block can move between a locking position and an unlocking position along the direction perpendicular to the inserting direction; the metal elastic piece exerts an elastic action on the locking piece; and the slide rod is arranged on the charging plug and can move back and forth along the horizontal direction. The locking block bears and maintains the longitudinal acting force that the locking block moves to the locking position or the unlocking position. The slide rod and the locking block are provided with mutually matched slopes, and the slide rod can provide resisting and pushing force opposite to the longitudinal acting force to the locking block through the slopes. When the slide rod is driven to move along the horizontal direction, the locking block can move between the unlocking position and the locking device. The structure capable of locking can enable the socket to be stably connected with a plug connector when the socket is matched with the plug connector, and the phenomenon of separation can not happen.
