Safety charger with overcurrent protection function

Abstract

The utility model discloses a safety charger with an over-current protection function, which comprises a charger main body, two sides of the charger main body are respectively provided with a conductive head part and a connecting wire part, and the upper part and the lower part of the charger main body are respectively provided with a heat dissipation plate, the charger main body is externally provided with a U-shaped shell, and the upper part and the lower part of the charger main body are respectively provided with a heat dissipation plate. A first spring is arranged between the U-shaped shell and the charger body, cuboid strip rods are arranged on the two sides of the upper portion of the U-shaped shell, the head portions of clamping pieces of the cuboid strip rods are inserted into the inserting hole portions of the charger body, the head portions of the clamping pieces are clamped between the two U-shaped hooks, and a conical pressing block is arranged on the other side of each inserting hole portion. And a third spring is arranged between the sliding block part of the conical pressing block and the second sliding groove part, and meanwhile, the conical end of the conical pressing block is inserted between the two U-shaped hooks, so that effective heat dissipation can be carried out on the charger under the charging condition by utilizing the structure, meanwhile, the stress length of the connecting wire can be increased by moving out the U-shaped shell, and the problem of fracture at the connecting part of the connecting wire is avoided.
