[0002] The rechargeable battery is widely used in various electronic devices, which can improve the mobile portability of the electronic devices to adapt to more application scenarios. The battery is charged by an external alternating current charger when its power is consumed. Chinese Utility Model Patent No. CN220653728U discloses a charger, which includes an insulating shell, a heat dissipation shell and two end covers. The insulating shell and the heat dissipation shell are both cylindrical structures with two open ends, and the heat dissipation shell is sleeved in the insulating shell. The two end covers are respectively arranged at the two open ends of the insulating shell and are buckled with the heat dissipation shell. The end cover has an annular sealing groove for fixing a sealing ring, and the openings of the insulating shell and the heat dissipation shell are inserted into the sealing groove. In addition, the end cover and the heat dissipation shell or the insulating shell can also be connected by screws. In the charger, there is no connecting structure between the insulating shell and the heat dissipation shell, which causes the insulating shell and the heat dissipation shell to be easily displaced during assembly, affecting the assembly efficiency.

[0003] In addition, in order to facilitate the simultaneous charging of multiple batteries, the charger is usually provided with multiple charging compartments for inserting batteries and a circuit board for controlling and charging the batteries inserted into the charging compartments. Therefore, the charger usually needs multiple sub-shells to fix or form the charging compartments and fix the circuit board. When the number of sub-shells is large, in order to ensure the close combination and assembly stability between the sub-shells, if all the sub-shells are fixed by screws, corresponding screw holes, stud columns and screw installation operation spaces need to be designed, and because multiple charging compartments are provided, the charger has a large size, which will inevitably require more screws to fix the sub-shells to ensure the assembly stability, resulting in a complex structure of the charger and affecting the assembly efficiency.

[0004] Therefore, it is necessary to design a charger that can improve the assembly efficiency while ensuring the assembly stability between the sub-shells. Utility Model Content
