[0036] The charging wire 13 includes plug 11, plug seat 12 and electric wire 13, the plug 11 and electric wire 13 are all arranged on plug seat 12 and are electrically connected with each other along the axial direction. The plug seat 12 includes the abutting portion 121 and the penetrating portion 122 connected, the plug 11 is arranged on the penetrating portion 122, and the electric wire 13 is arranged on the abutting portion 121. The cross-sectional shape of the penetrating portion 122 can be preferably designed as the same as the shape of the plug 11, and the cross-sectional dimension is greater than the cross-sectional dimension of the plug 11.

[0037] Please refer to Figures 7-12 , Figure 7 is a front axial view of the shell; Figure 8 is a back axial view of the shell; Figure 9 is a structural view of the limiting seat; Figure 10 is a structural view of the dust cover; Figure 11 is a front view of the gland; Figure 12 is Figure 11 is a sectional view along AA direction.

[0038] The protective sleeve comprises a shell 21, a limiting seat 22, a dust cover 23 and a gland 24. The shell 21 is provided with an open end, and a sliding cavity 211 in communication with the open end is further formed in the shell 21. The sliding cavity 211 penetrates the shell 21 along the axial direction, and the plug seat 12 of the charging wire 13 slides in the sliding cavity 211. As preferred, in order to avoid the rotation of the charging wire 13 relative to the protective sleeve during the sliding process, a sliding boss 212 extending along the axial direction is arranged in the sliding cavity 211. The cross-sectional shape of the abutting portion 121 is adapted to the sliding cavity 211, and a sliding groove 123 is arranged on the sidewall of the abutting portion 121 and is in sliding cooperation with the sliding boss 212. The cross-sectional shape of the sliding cavity 211 can be designed according to the product requirements. In the embodiment, the sliding cavity 211 is cylindrical, and the abutting portion 121 is cylindrical.

[0039] The limiting seat 22 is arranged in the sliding cavity 211, and a first positioning boss 213 is arranged on the inner wall of the sliding cavity 211. A first positioning groove 221 is formed in the limiting seat 22 and is in clamping cooperation with the first positioning boss 213, so as to realize the positioning of the limiting seat 22 and the shell 21. An inclined first guide surface 214 is further arranged on the first positioning boss 213, so as to facilitate the installation of the limiting seat 22. An elastic buckle 222 is further arranged in the first positioning groove 221. When the plug 11 slides into the sliding cavity 211 and the charging wire 13 is in the storage state (as shown in Figure 3

[0040] ​As preferred, the clamping groove 124 is tapered from outside to inside, thereby forming an inclined guide side wall 126. The abutting portion 121 is further provided with a guide slot 127, which is axially located on the side of the clamping groove 124 away from the plug 11. The side of the guide slot 127 away from the clamping groove 124 penetrates the abutting portion 121 and is provided with an inclined first guide surface 128, which gradually rises towards the guide slot 127. The side of the guide slot 127 close to the clamping groove 124 is spaced apart from the clamping groove 124 and is provided with an inclined second guide surface 129, which has the same inclination direction as the first guide surface 128, facilitating the sliding of the clamping boss 223 in and out.

[0041] The dustproof cover 23 covers the open end of the shell 21 and is provided with a movable portion 231 which can be pushed open by the charging wire 13, thereby allowing the plug 11 to penetrate the dustproof cover 23 and connect with external terminals while keeping dustproof. The movable portion 231 can have various structural forms, for example, the dustproof cover 23 comprises a cover body connected with the shell 21, the cover body is provided with an opening, and the movable portion 231 is movably arranged in the opening, which can be directly connected with the cover body or connected with the cover body through a rotating shaft or other structures, or the cover body and the movable portion 231 are integrally connected, and the movable portion 231 can be a sheet structure made of hard or elastic material. In the embodiment, the dustproof cover 23 is made of flexible material, preferably soft rubber or the like, and is provided with a penetrating seam corresponding to the plug 11. The plug 11 and the penetrating portion 122 can penetrate the penetrating seam.

[0042] The penetrating seam can be only one straight gap, which has a length greater than the circumference of the plug 11, so that the plug 11 can penetrate out; or can include a first gap 232 and a second gap 233 intersecting with the first gap 232, forming a cross or T-shaped structure or the like. As preferred, the penetrating seam includes a first gap 232 extending in the diameter direction, and a second gap 233 symmetrically provided at both ends of the first gap 232 and communicating with the first gap 232, and the two second gaps 233 do not intersect. For example, the first gap 232 is provided with one, extending in the diameter direction; the second gap 233 is provided with two, symmetrically provided at both ends of the first gap 232, one end of the two second gaps 233 is connected with the first gap 232, the other end of the two second gaps 233 extends along the same side and does not intersect; and the other end of the two second gaps 233 forms a connecting portion of the cover body and the movable portion 231. The two ends of the second gap 233 extend away from the first gap 232, thereby forming two symmetric and openable movable portions 231 in the dustproof cover 23. The shape of the second gap 233 can be designed according to product needs, and in the embodiment, the two second gaps 233 are arc-shaped and located on the same arc.

[0043] In order to improve the appearance of the product, the dust cover 23 is provided with a gland 24, the gland 24 is detachably connected with the shell 21, the dust cover 23 is covered in the interior and is pressed to the shell 21. The shell 21 is further provided with a second positioning boss 215, the gland 24 is provided with a second positioning groove 241 matched with the second positioning boss 215, so that the gland 24 is prevented from being deflected relative to the shell 21. The second positioning boss 215 is further provided with an inclined second guide surface 216, so as to facilitate the installation of the gland 24. The gland 24 is provided with an avoiding hole 242 through which the plug 11 and the penetrating part 122 pass. The penetrating part 122 is provided with an abutting boss 125, when the plug 11 passes through the avoiding hole 242 and extends from the gland 24, the charging wire 13 is in an extended state (as shown in Figure 4

[0044] When the charging wire 13 needs to be used, the charging wire 13 is pushed, because the movable part 231 is arranged on the sliding path of the plug 11, the plug 11 slides forward to push away the movable part 231 of the dust cover 23 and passes out of the dust cover 23. Then the charging wire 13 is continuously pushed, so that the plug 11 passes through the avoiding hole 242 and passes out of the protective sleeve, so that the plug 11 extends, and a user can be connected. At this time, the abutting boss 125 abuts against the gland 24, and the position of the plug 11 is limited.

[0045] When the charging wire 13 does not need to be used, the charging wire 13 is pulled to reset, the plug 11 slides into the sliding cavity 211, the movable part 231 of the dust cover 23 resets and is in a closed state, so that external dust and moisture are prevented from contacting the plug 11, and dust and water proof effects are achieved. At this time, the elastic buckle 222 is buckled into the buckling groove 124, so that the plug 11 is limited and fixed.

[0046] The protective sleeve and the charging assembly thereof have the advantages that the two requirements of dustproof storage and plug connection can be realized through the sliding of the charging wire, the operation is simple and convenient, and the charging wire can be adapted to charging lines of various plug shapes.
