Description

Technical Field

[0001] This utility model relates to the field of motorcycles, and in particular, to a dedicated wiring harness for motorcycle heated grips and its core wiring harness structure. Background Technology

[0002] Currently, Chinese patent CN215643759U discloses a wire harness designed to solve the problem of exposed wires in foamed wire harnesses. This wire harness includes a wire harness body, a winding layer, and a covering layer arranged sequentially from the inside out. By spaced outlying multiple first support members on the side of the winding layer away from the wire harness body, and by placing at least a portion of the covering layer in the area between adjacent first support members, the wire harness body is centered within the injection mold, resulting in a more uniform covering layer on the outside of the wire harness body, thus preventing wire harness exposure.

[0003] However, after repeated damage, this type of wire harness may experience internal conductor breakage due to metal fatigue. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a special wire harness for motorcycle heated grips and its core wire harness structure, which, by setting reinforcing ribs, makes the conductor less prone to breakage.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a core wire harness structure, including an outer insulating layer and a conductor, wherein the conductor is disposed inside the outer insulating layer, and further including reinforcing ribs, wherein the reinforcing ribs are located inside the outer insulating layer and are twisted together with the conductor.

[0006] To achieve the above technical solution, the reinforcing ribs improve the toughness of the wire harness. By using the reinforcing ribs to pull the conductor to bend naturally, the metal fatigue phenomenon is reduced, thereby giving the wire harness a better folding life and making it less prone to breakage.

[0007] As a preferred embodiment of the present invention, it further includes a spring wire, which is located inside the outer insulating layer, and a plurality of conductors are twisted and arranged along the spring wire.

[0008] To achieve the above technical solution, the spring wire has toughness, making the conductor less prone to breakage.

[0009] In a preferred embodiment of this utility model, at least two spring wires and at least two reinforcing ribs are provided, and the plurality of spring wires and the plurality of reinforcing ribs are spaced apart along the axis of the outer insulating layer.

[0010] The above technical solution further enhances the toughness of the wire harness, making the conductor less prone to breakage.

[0011] As a preferred embodiment of this utility model, it also includes an inner insulating layer, wherein the elastic wire and the conductor are both located inside the inner insulating layer, and the inner insulating layer is twisted together with the reinforcing ribs.

[0012] The above technical solution improves insulation and makes the conductor less prone to breakage.

[0013] In a preferred embodiment of this invention, each of the spring wires is provided with 95-110 conductors, and the total cross-sectional area of ​​the conductors is ≥0.5mm². 2 .

[0014] The above technical solution involves a large number of conductors, resulting in minimal breakage of individual conductors under stress.

[0015] As a preferred embodiment of this utility model, the outer diameter of the spring wire is 0.15mm-0.22mm.

[0016] In a preferred embodiment of this utility model, the outer diameter of the conductor is 0.06mm-0.1mm.

[0017] In a preferred embodiment of this utility model, the outer diameter of the inner insulating layer is 1.2mm-1.6mm.

[0018] As a preferred embodiment of this utility model, the outer diameter of the outer insulating layer is 4.5mm-4.8mm.

[0019] This utility model also discloses a motorcycle heating grip sleeve, and a core wire harness structure.

[0020] The above technical solution ensures that the wiring harness is less prone to breakage during repeated bending, thus extending the service life of the motorcycle heated grip. Attached Figure Description
