Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile wiring harnesses, and specifically relates to a flame retardant and anti-aging wiring harness for new energy vehicles. Background Art
[0002] The automotive wiring harness is distributed in all corners of the frame. Some of the wiring harnesses are in a bent or even twisted state. The inside and surface of the wiring harness will produce pulling and squeezing forces. If it is in this state for a long time, the degree of local aging of the wiring harness will be faster than other parts. Usually, the inner and outer insulation layers will rupture, and natural phenomena may also occur. In order to solve this problem, a flame-retardant and anti-aging wiring harness for new energy vehicles is provided. Utility Model Content
[0003] In view of this, the technical problem to be solved by the utility model is to provide a flame retardant and anti-aging wiring harness for new energy vehicles, which solves the problem of inner and outer skin cracking caused by long-term bending of the wiring harness in the prior art.
[0004] In order to solve the above technical problems, the utility model discloses a flame-retardant and anti-aging wiring harness for new energy vehicles, including: multiple conductors; an insulating layer wrapped around the surface of the conductor; a ring array of multiple conductors is embedded at the edge of an insulating filling body, a hole is provided in the middle of the insulating filling body, a nylon wire is passed through the hole, the outside of the insulating filling body is wrapped with an insulating layer, the outside of the insulating layer is wrapped with a shielding layer, the outside of the shielding layer is wrapped with a flame-retardant layer, and the outside of the flame-retardant layer is wrapped with a protective layer.
[0005] Furthermore, the insulating filling body is cylindrical, and a plurality of embedding grooves are arranged on the circumference of the surface thereof, and through holes are arranged between the embedding grooves.
[0006] Furthermore, the embedding groove extends spirally to both ends of the insulating filling body.
[0007] Furthermore, the above-mentioned insulating filling body is made of soft material.
[0008] Furthermore, the thickness of the protective layer is three times that of the insulating layer.
[0009] Compared with the prior art, the present application can obtain the following technical effects:
[0010] The utility model arranges an insulating filling body inside the wiring harness, and arranges a nylon wire in the middle of the insulating filling body. When the wiring harness is bent or twisted, the nylon wire exerts a certain pulling force to prevent the wiring harness from excessive bending. The insulating filling body has resilience, which can make the locally bent wiring harness have a strong anti-bending performance, so that the locally bent inner and outer surfaces are supported by the insulating filling body, reducing the concentration of extrusion force and pulling force, thereby improving the life of the wiring harness.
[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application.

[0016] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0017] Please refer to Figure 1 , Figure 1 It is a schematic cross-sectional view of a wire harness according to an embodiment of the present invention.
[0018] A flame-retardant and anti-aging wiring harness for new energy vehicles, comprising: a plurality of conductors 1; an insulating layer 2 wrapped around the surface of the conductor 1; a plurality of conductors 1 are embedded in a ring array at the edge of an insulating filler 3, a hole is provided in the middle of the insulating filler 3, a nylon wire 4 is passed through the hole, the insulating filler 3 is wrapped around the insulating layer 2 on the outside, the insulating layer 2 is wrapped around the shielding layer 5 on the outside, the shielding layer 5 is a woven copper mesh, the shielding layer 5 is wrapped around the flame-retardant layer 6 on the outside, the flame-retardant layer 6 is wrapped around the protective layer 7 on the outside, and the flame-retardant layer 6 is an aluminum foil thermal insulation coil.
[0019] The insulating filler 3 is cylindrical, and a plurality of embedding grooves 8 are provided on the circumference of its surface. A through hole 9 is provided between the embedding grooves 8. The through hole 9 enables the insulating filler 3 to have better resilience and shock resistance. Another implementation method is to extend the embedding grooves 9 in a spiral shape to the two ends of the insulating filler 3 so that the multiple conductors 1 are also spiral. The insulating filler 3 is a single-component curing silicone material, which has the characteristics of shock resistance, moisture resistance, insulation, and corona resistance. The thickness of the protective layer 7 is three times that of the insulating layer 2.

When the wiring harness is bent or twisted, the nylon wire 4 exerts a certain pulling force to prevent the wiring harness from excessively bending. The insulating filling body 3 has resilience, which can make the locally bent wiring harness have a strong anti-bending performance, so that the locally bent inner and outer surfaces are supported by the insulating filling body 3, reducing the concentration of extrusion force and pulling force, thereby improving the life of the wiring harness.
