For details, please refer to Figure 1 , such as Figure 1 shown, the conductor 2 of the multi-core wire is wound by several core wires. The outside of the conductor 2 is wrapped with an insulating layer 3. The outside of the cable 1 is wrapped with a polyester film 4. When arranging the multi-core wire with a circular outer contour, it is not easy to stably abut against the installation surface, and an external fixing structure is required to achieve the installation and fixing effect. In addition, the circular outer contour easily causes the multi-core wire to rotate and entangle with each other or itself.

[0003] Therefore, it is necessary to provide a multi-core wire with a planar structure and a protection structure. Summary of the Utility Model

[0004] The utility model provides a multi-core wire with a protection structure to solve the above technical problems.

[0005] To achieve the above object, an embodiment of the utility model provides a multi-core wire with a protection structure, including: a wrapping layer, an insulating layer and a plurality of wire cores.

Both the wrapping layer and the insulating layer include an arc surface part and a planar part. At least one dividing groove is arranged on the planar part.

[0006] Further, the vertical section of the dividing groove is "V" shaped.

[0007] Further, a positioning section is formed between two adjacent dividing grooves.

[0008] Further, a connecting structure is arranged at the center position of each positioning section.

[0009] Further, the connecting structure includes an adhesive layer and a film. One side of the adhesive layer is arranged on the insulating layer, and the other side is connected to the film.

[0010] Further, the length and width of the film are both larger than the length and width of the adhesive layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By arranging the planar part, it is convenient for the arrangement of the multi-core wire, and in addition, the probability of the multi-core wire rotating and causing entanglement is reduced;

[0013] The deformation on the surface at the bending position of the multi-core wire is compensated by reducing the opening of the V-shaped groove, preventing the crease from extending to breakage;

[0023] The present utility model will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0024] Please refer to Figure 2 , Figure 2 is a partial perspective view of the optimal embodiment of the multi-core wire with a protective structure of the present utility model. As Figure 2As shown, at least one embodiment provides a multi-core wire with a protection structure, including: a wrapping layer 100, an insulating layer 200, and a plurality of wire cores 300. The wrapping layer 100 wraps around the wire cores 300, and the insulating layer 200 is disposed on the outer wall of the wrapping layer 100. Both the wrapping layer 100 and the insulating layer 200 include an arc-shaped surface portion and a flat portion 400. Specifically, the outer contour of the wrapping layer 100 is a circle with a part of the arc cut off, and the cut surface is linear. Since the insulating layer 200 is wrapped on the outer wall of the wrapping layer 100, both the wrapping layer 100 and the insulating layer 200 include an arc-shaped surface portion and a flat portion 400. The purpose of the existence of the flat portion 400 is to facilitate the arrangement of the multi-core wires, reduce the path chaos when multiple multi-core wires exist simultaneously. Additionally, compared with the multi-core wire with a circular outer contour centered on the circle, the multi-core wire with the flat portion 400 is not prone to twisting, thereby reducing the winding probability.

[0025] Please continue to refer to Figure 2 and in combination with Figures 4 to 6 , Figure 4 which is a partial structural schematic diagram of the optimal embodiment of the flat portion of the present utility model; Figure 5 which is a partial sectional view of the optimal embodiment of the multi-core wire with a protection structure of the present utility model. As Figure 2 , Figures 4 to 6 shown, in order to prevent creases from appearing on the surface of the multi-core wire in a bent state, at least one dividing groove 402 is provided on the flat portion 400. The vertical cross-section of the dividing groove 402 is a "V" shape. When it is necessary to bend the wire core, select to bend at the position of the dividing groove 402 to change the arrangement direction of the wire core, that is, bend the multi-core wire at the position of the V-shaped groove. By reducing the opening of the V-shaped groove, the deformation of the surface at the bent position of the multi-core wire is compensated. Therefore, the existence of the dividing groove 402 prevents the creases from extending to breakage. A positioning section 401 is formed between two adjacent dividing grooves 402. The flat positioning section 401 is used to abut the multi-core wire against the electric bicycle.

[0026] A connecting structure 403 is provided at the center position of each positioning section 401. The connecting structure 403 includes an adhesive layer 4031 and a film 4032. One side of the adhesive layer 4031 is disposed on the insulating layer 200, and the other side is connected to the film 4032. The length and width of the film 4032 are both greater than the length and width of the adhesive layer 4031. When it is necessary to fix the multi-core wire, the film 4032 can be removed, and the adhesive layer 4031 can be positioned on the electric bicycle to be installed, improving the installation stability of the multi-core wire and reducing the installation difficulty of the arrangement of the multi-core wire.

[0027] In summary, by providing the flat portion 400, the arrangement of multi-core wires is facilitated, and the probability of entanglement caused by the multi-core wires twisting is reduced; by reducing the opening of the V-shaped groove to compensate for the deformation on the surface of the bending position of the multi-core wires, the crease is prevented from extending to fracture; by providing the connection structure 403, the installation stability of the multi-core wires is improved, and the installation difficulty of the multi-core wires arrangement is reduced.
