The opening 14 is disposed on one side of the end wall 103 . The receiving groove 12 is roughly a bar-shaped groove, which is arranged on the bottom plate 101 adjacent to the side wall 102 and adjacent to the battery 16 and the circuit board 11, and is compactly arranged in the housing 10, saving the housing 10 volume of. The portable mobile power supply 100 also includes a cover plate covering the casing 10 , and the cover plate seals the circuit board 11 , the battery 16 and the data cable 20 in the casing.

Further, the receiving groove 12 includes a first groove portion 121 and a second groove portion 123 communicating with the first groove portion 121, the second groove portion 123 communicates with the opening 14, and the USB plug 23 is installed in the second groove portion 123. In the groove portion 123 , the USB plug 23 and the second groove portion 123 in this embodiment are fixed by friction. Specifically, the USB plug 23 includes a shell 231 and a plug 232 installed at one end of the shell 231 . The shape of one side of the shell 231 is exactly the same as the contour shape of the opening 14. When the USB plug 23 is installed in the receiving groove 12, the side of the shell 231 exposed to the opening 14 just covers the opening 14 and is in contact with the shell. The end wall 203 of 10 forms a complete shell part, and such a design ensures the integrity of the appearance of the shell without damaging the appearance.

In this embodiment, one side of the housing 231 is a plane with an arc-shaped surface at one end, and the opening 14 is opened at a corner close to the housing 10 , and the housing 231 can just cover the opening 14 . It can be understood that in order to prevent the USB plug 23 from falling out of the second groove 123 , a limiting structure can be provided in the second groove 123 , such as a buckle that can hold the shell 231 .

Further, the first groove portion 121 includes a groove bottom wall (not shown), two opposite groove side walls 124 disposed on the groove bottom wall, and a groove end wall 125 connecting the two groove side walls 124 . The partition 13 is located on the bottom wall 124 of the tank and is located between the two tank side walls 124 and is spaced apart from the tank end wall 125, so that the partition 13 and the two tank side walls 124 form a first chute 126 and the second chute 127 communicating with the first chute 126 . The second chute 127 communicates with the second groove portion 123 and accommodates the insertion section 22 , the connecting section 21 is located in the first chute 126 and bypasses the partition 13 to connect with the insertion section 22 . Segment 22 is connected. Specifically, the first chute 126 is arranged parallel to the second chute 127 , and the end of the second chute 127 away from the end wall 126 of the chute communicates with the opening 14 . There is a certain distance between the groove end wall 125 and one end of the partition 13 for the connecting section 21 to pass through.

Further, the end of the partition 13 facing the opening is the first end 131, and the end away from the opening is the second end 132, and the gap 15 is opened parallel to the partition 13 from the second end 132 to the first end 131. .
