[0001] The utility model relates to the technical field of on-board chargers, in particular to a portable on-board charger. Background Art

[0002] On-board chargers are divided into two types: integrated and split. One end of the integrated on-board charger is a charging head connected to the vehicle socket, and the other end is a plug that can be inserted into a household socket, and the middle is connected by a charging cable; the middle charging cable of the split on-board charger is equipped with a plug connector, which can easily replace the electrical connector at one end. At the same time, various indicator functions can be added to the plug connector to facilitate the owner to check the vehicle status. The split on-board charger has extremely broad applications due to the above advantages.

[0003] Chinese patent publication number "CN218771366U" discloses an on-board charger. The on-board charger comprises a male connector and a control box. A guide slot is axially defined on the outer wall of the male connector, one end of which extends through the first end of the connector. The other end of the guide slot is connected to a latching slot, which extends circumferentially along the outer wall of the male connector. The control box also houses a female connector, with a latching block on its inner wall. When the male connector is inserted into the female connector, the latching block slides along the guide slot into the latching slot.

[0004] However, this charger still has some shortcomings. Since the charger's power supply system is operated through the components inside the casing, when the charger is damaged and needs to be repaired, the casing must be removed first. However, the existing charger casing is mostly installed by threaded fixing. Therefore, the user needs to unscrew all the bolts on the outside of the casing before it can be disassembled, which wastes time and slows down the repair progress. For this reason, we have specially proposed a portable on-board charger. Utility Model Content
