Referring to fig. 2, in some embodiments, the groove 30 includes a first engaging portion 30b and a second engaging portion 30a that are connected to each other. The data line 20 further includes an interface terminal 20b connected to the lead terminal 20 a. The interface end 20b is provided at the first catching portion 30 b. The lead terminal 20a is provided at the second engaging portion 30 a. In this embodiment, the first end of the data line 20 including the lead terminal 20a is electrically connected to the built-in circuit board 60. A second end of the lead terminal 20a is connected to the interface terminal 20 b. The interface terminal 20b is electrically connected to the built-in circuit board 60 through the lead terminal 20 a. The first engaging portion 30b is used for placing the interface end 20b of the data line 20. The second engaging portion 30a is used for placing the lead terminal 20a of the data line 20. By effectively using the housing 10, the overall size of the portable power supply 100 can be reduced, and the portable power supply is convenient to carry.

Fig. 9 is a top view of the portable power bank 100 shown in fig. 1 from another angle. As shown in fig. 9, in some embodiments, the second engaging portion 30a has a U-shaped structure. Because the length of the data line 20 is long, the second engaging portion 30a may be configured to have a U-shaped structure, which facilitates the flexible bending and embedding of the data line 20. The spacing L between the two sides of the U-shaped structure is at least 3mm and not more than 9 mm. Further, the wire body 35 of the data wire 20 has a diameter of 3 mm. Therefore, the data line 20 can be flexibly and conveniently bent and placed in the groove 30, and the effect of accommodating the longer data line 20 is good. In some embodiments, the second engaging portion 30a may also have an S-shaped structure.

In some embodiments, the edge of the first engaging portion 30b facing away from the second engaging portion 30a is provided with a notch 10 b-1.

Referring to fig. 2 and 8, in some embodiments, a plane (e.g., X-plane in fig. 2) of the plugging direction of the interface end 20b is parallel or perpendicular to the third side 10 d. In this embodiment, the first engaging portions 30b with different shapes are disposed, so that the plane of the insertion direction of the interface end 20b is parallel to or perpendicular to the third side 10d, thereby realizing diversification of the interface end 20b disposed on the first engaging portion 30 b.

In some embodiments, when the plane of the plugging direction of the interface end 20b is parallel to the third side surface 10d, the depth of the first engaging portion 30b is the first depth. When the plane of the insertion direction of the interface end 20b is perpendicular to the third side surface 10d, the depth of the first engaging portion 30b is the second depth. The first depth is less than the second depth. Since the thickness and the width of the socket end 20b are different, the depth of the first engaging portion 30b when the plane of the socket end 20b in the inserting direction is parallel to the third side 10d is different from the depth of the first engaging portion 30b when the plane of the socket end 20b in the inserting direction is perpendicular to the third side 10d, and the depth of the former is smaller than that of the latter. The shapes of the two first clamping parts 30b can enable the interface end 20b embedded in the first clamping part 30b to be basically flush with the third side surface 10d, so that the carrying and the use of a user are convenient.

Fig. 10 is an exploded view of the portable mobile power supply 100 shown in fig. 1.

At this time, the second slot 50 is on a linear path segment of the latch of the power tool apparatus 200b, and therefore, a structure needs to be provided such that the latch structure in the power tool apparatus 200b does not match the first slot 40, but only the second slot 50. So configured, the first and

second slots

40 and 50 do not interfere with each other, and the matching use of the portable mobile power source 100 and the electric power tool 200b is not affected. Similarly, when the portable mobile power source 100 is detached from the power tool 200b along the unlocking detachment path n, the first latch groove 40 does not match with the latch structure in the power tool 200b, does not interfere with the second latch groove 50, and does not affect the matching of the portable mobile power source 100 and the power tool 200 b.
