Charging automatic protection device and equipment

The invention, which belongs to the electrical control field, particularly discloses a charging automatic protection device. An equipment load is connected to an output loop of a rechargeable storage battery; and a positive end and a negative end of the storage battery are connected with a charging terminal into which a charger terminal can be inserted. The device comprises a travel switch that can sense insertion of the charger terminal into the charging terminal and enables the output loop of the storage battery to be changed into a breaking state. According to the invention, the misoperation occurring in the equipment charging process can be prevented and setting of a plurality of terminals for replacement is not required, so that the operation becomes simple and convenient and the service life of the terminal is prolonged; and the charging terminal is only used for charging, so that the cost wasting caused by terminal mismatching can be avoided.
