Further, the length of the charging wire 70 from the junction with the main body part 20 to the junction with the charging circuit 60 is greater than the distance between the junction of the charging wire 70 and the main body part 20 to the junction of the charging wire 70 and the charging circuit 60, so that the charging wire 70 located in the accommodating space 21 of the main body part 20 is bent and coiled, the possibility of the occurrence of the disengagement of the charging wire 70 and the charging circuit 60 due to the pulling of the charging wire 70 in the using process can be further reduced, and the stability of the charging assembly is improved.

The charging wire 70 may include a core wire 71 and a protective sheath 72, wherein the protective sheath 72 is at least sleeved on the periphery of the core wire 71 outside the main body 20 for protecting the core wire 71.

At this time, the core wire 71 can be fixed with the protective sheath 72 coated on the periphery at the through hole 22, and the protective sheath 72 coated on the periphery is further fixed with the main body portion 20 at the through hole 22, so that the charging wire 70 is fixedly connected with the main body portion 20.

Further, the charging cord 70 may further include an intermediate layer 73, wherein at least a portion of the intermediate layer 73 outside the body portion 20 extends in the extending direction of the core wire 71 and is covered by the protective sheath 72. Specifically, the middle layer 73 may include a shielding layer and a filling layer, wherein the shielding layer may be an aluminum wire or an aluminum foil, and the filling layer may include a cotton thread and a yellow bladder thread, which may be specifically set according to actual requirements, and are not specifically limited herein.

Note that, if the charging cord 70 is directly fixed to the main body portion 20, the fixing area of the charging cord 70 to the main body portion 20 is limited due to the structure of the charging cord 70 itself. In the present embodiment, the intermediate layer 73 is wound around the periphery of the core wire 71 at least at the through hole 22, specifically, may be wound around the periphery of the core wire 71 at a side of the through hole 22 facing the accommodating space 21, and is fixed to the main body portion 20 at the through hole 22 together with the wound core wire 71, specifically, the fixing may be achieved by an adhesive bonding or a hot melting manner.
