Therefore, the joint of the first housing 110 is elastically deformed and attached to the second housing 120 after being extruded by the second housing 120, so as to achieve sealing connection, and during assembly, there is no need to manually add components such as sealing strips and additional processes such as brushing waterproof materials, so as to improve the assembly production efficiency of the power supply device 100.

It should be noted that, the first casing 110 and the second casing 120 are connected to form an inner cavity 101, the inner cavity 101 is used for installing power related components, the power related components include but are not limited to, for example, a battery, a super capacitor, a control circuit board, etc., in order to enable the power supply device 100 to supply power to the outside, an input/output interface 115 is arranged on the first casing 110 and/or the second casing 120, and an external device is plugged into the input/output interface to take power or supply power.

In this embodiment, the first housing 110 includes a first main housing 112 and a first sub-housing 113, the first housing 110 is hermetically connected to the second housing 120 through the first sub-housing 113, and a connection point of the first housing 110 is located on the first sub-housing 113.

So, junction 111 on the first subshell 113 produces deformation and the laminating of second casing 120 when the extrusion, and first main shell 112 can be difficult for producing deformation, makes first subshell 113 be pressed from both sides between first main shell 112 and second casing 120, makes the laminating inseparabler, realizes sealing connection. In this embodiment, in order to increase the sealing performance, a protrusion 102 is disposed at a joint of one of the first sub-housing 113 and the second housing 120, a groove 103 is disposed at a joint of the other, and the protrusion 102 and the groove 103 are engaged with each other, so that the first sub-housing 113 and the second housing 120 are hermetically connected.
