Abstract
The utility model relates to a charging socket and a plug, wherein the charging socket comprises a seat casing and a terminal fixedly connected onto the seat casing. The inner end of the terminal is situated in a slot in the seat casing, and the outer end extends out of the seat casing. A protective cover capable of covering the opening of the slot is hinged at the slot end of the seat casing. The plug comprises an insertion portion inserted in the slot and an exposure portion, and a cable is connected to the tail portion of the exposure portion. A bayonet hole is arranged at one side where the protective cover is hinged to the seat casing, and a clamping block matching with the bayonet hole is arranged on the exposure portion of the plug. One end of the clamping block tightly presses against a joint between the insertion portion and the exposure portion. When the charging socket is inserted in the plug, the connection between the charging socket and the plug is tighter and more reliable, and is unlikely to loosen, through the cooperation between the bayonet hole and the clamping block, thereby ensuring smooth charging, prolonging the service lifetime of a storage battery, and preventing occurrence of short circuit and charging contact failure.
