DETAILED DESCRIPTION

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0015] Example

[0016] To address the aforementioned technical problems, this embodiment provides an electromagnetic interference-resistant electric bicycle charging cable, such as... Figure 1 As shown, the cable includes an outer sheath 10, within which a core wire assembly 20 is disposed. The core wire assembly 20 includes a power wire assembly 21 and a control wire assembly 22 arranged parallel to each other and abutting each other, several signal display lines 23 arranged on both sides of the power wire assembly 21 within the outer sheath 10, and a ground wire 24 disposed on one side of the power wire assembly 21. An elastic filler 25 is also filled in the cavity formed between the outer sheath 10 and the core wire assembly 20. A first shielding layer 30 is also wrapped around the outer periphery of the core wire assembly 20 within the outer sheath 10. The cable is equipped with a power wire assembly 21 and a control wire assembly 22 arranged parallel to each other and abutting each other, several signal display lines 23 arranged on both sides of the power wire assembly 21, and a ground wire 24 disposed on one side of the power wire assembly 21. The core wire group 20, consisting of the ground wire 24 on one side of the source wire group 21 and the elastic filler 25 filling the cavity inside the cable sheath 10, can effectively improve the roundness of the charging cable's shape, making the force more even when the charging cable is bent. Furthermore, by covering the core wire group 20 with a first shielding layer 30, electromagnetic interference that may be generated inside the charging cable can be effectively shielded, ensuring the stability of the charging cable during operation and effectively reducing the generation of interference current. Moreover, by covering the first shielding layer 30 with the cable sheath 10, the physical properties of the charging cable can be effectively improved, thereby ensuring the long service life of the charging cable. This achieves effective shielding of electromagnetic interference and reduces the generation of interference current.

[0017] Specifically, the power line group 21 includes a twisted power line core 211, and a first inner sheath 212 covering the twisted power line core 211. A second shielding layer 213 is further covered on the outer periphery of the first inner sheath 212. By covering the first inner sheath 212 on the outer periphery of the twisted power line core 211, the conductors in the twisted power line core 211 can be effectively protected from damage by the first inner sheath 212. By further covering the second shielding layer 213 on the outer periphery of the first inner sheath 212, the twisted power line core 211 can effectively resist electromagnetic interference generated during power transmission by the second shielding layer 213. Thus, the transmission stability of the twisted power line core 211 in complex electromagnetic interference conditions can be ensured, thereby reducing the power waste caused by the composite interference current. In some embodiments, the twisted power line core 211 and the second shielding layer 213 are twisted by a one-time cabling process. The twisting pitch of the power line group 21 is equal to the total twisting pitch of the charging line. Thus, the twisted power line core 211 does not need to be turned over during the covering of the second shielding layer 213. The electromagnetic interference that may be generated by the power line group can be effectively shielded to reduce the generation of interference current.

[0018] Further, the control line group 22 includes a twisted charging control line core 221, and a third shielding layer 222 covering the twisted charging control line core 221. A plurality of power control line cores 223 abutting the twisted charging control line core 221 are further arranged in the third shielding layer 222. In some embodiments, the conductors in the twisted charging control line core 221 and the power control line core 223 are further made of 500D nylon wire material. Thus, the tensile strength of the twisted charging control line core 221 and the power control line core 223 can be effectively increased. In some embodiments, the control line group 22 is twisted by a back-twist process during the total twisting of the charging line. Thus, the space occupied by the control line group 22 in the outer sheath 10 can be effectively reduced, thereby effectively reducing the bending stress inside the charging line. By covering the third shielding layer 222 on the outer periphery of the twisted charging control line core 221 and the power control line core 223, the twisted charging control line core 221 and the power control line core 223 can effectively resist electromagnetic interference generated during power transmission by the third shielding layer 222. Thus, the transmission stability of the twisted charging control line core 221 and the power control line core 223 in complex electromagnetic interference conditions can be ensured, thereby reducing the power waste caused by the composite interference current.

[0019] As a preferred embodiment, the conductor wire diameter in the twisted power line core 211 is 0.127 mm.

[0020] As a preferred embodiment, the conductor wire diameter in the charging control wire core 221 and the power control wire core 223 is 0.08 mm.

[0021] In the above scheme, the cable outer sheath 10 and the first inner sheath layer 212 are made of PVC material. By using PVC material to make the cable outer sheath 10 and the first inner sheath layer 212, the PVC material has the characteristics of oil resistance, wear resistance, low temperature resistance and softness, thereby improving the physical strength of the charging cable, so that it can meet the long-term bending use condition of the charging cable, thereby significantly improving the service life of the charging cable.

[0022] In summary, in one or more embodiments of the present application, the present application is provided with a core wire group in the cable outer sheath, the core wire group includes a power line group and a control line group arranged in parallel and in contact with each other, a plurality of signal display lines arranged on both sides of the power line group in the cable outer sheath, and a ground wire arranged on one side of the power line group. The cavity formed by the core wire group in the cable outer sheath is also filled with an elastic filler. The first shielding layer is wrapped around the outer periphery of the cable outer sheath. By arranging the core wire group composed of the power line group and the control line group arranged in parallel and in contact with each other, the signal display lines arranged on both sides of the power line group, the ground wire arranged on one side of the power line group, and the elastic filler filled in the cavity of the cable outer sheath, the roundness of the charging cable can be effectively improved, and the stress is more uniform when the charging cable is bent. By wrapping the first shielding layer around the outer periphery of the core wire group, the electromagnetic interference that may occur in the charging cable can be effectively shielded to ensure the stability of the charging cable during operation, thereby effectively reducing the generation of interference current. By wrapping the cable outer sheath outside the first shielding layer, the physical properties of the charging cable can be effectively improved, thereby ensuring the long-term service life of the charging cable, effectively shielding the electromagnetic interference of the charging cable, and reducing the generation of interference current.

[0023] The above-described embodiments do not constitute a limitation on the scope of protection of the technical solutions. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments shall be included in the scope of protection of the technical solutions.
