Abstract
The utility model discloses a double-layer corrugated pipe for protecting an automobile wire harness, which comprises an outer corrugated pipe and an inner corrugated pipe, wherein the inner corrugated pipe is arranged at the inner side of the outer corrugated pipe; the outer corrugated pipe is made of PPV0 material, and the hardness is 70D-80D; the inner corrugated pipe is made of TPVV0 elastomer material, and the hardness is 60-70A. The utility model has reasonable structure design and convenient use; the outer corrugated pipe has higher hardness, so that the abrasion of external factors and the extrusion of the corrugated pipe can be prevented; the inner corrugated pipe has lower hardness and is soft, so that the inner wall of the corrugated pipe can be prevented from wearing the surface skin of the wire harness wire; the outer corrugated pipe is made of a PPV0 material meeting the UL-94V 0 flame-retardant standard, the inner corrugated pipe is made of a TPVV0 elastomer material meeting the UL94-V0 flame-retardant standard, and when the surface of the electric wire catches fire, the electric wire has the function of preventing or retarding the continuous combustion of fire; the utility model can effectively protect the wire harness in the environment of-40 ℃ to 150 ℃ in turn due to the special effect of the material.
Description
Technical Field
The utility model relates to the technical field of auto-parts, concretely relates to double-deck bellows is used in car wiring harness protection.
Background
At present, the protection mode of the truck wire harness in China is generally single-layer corrugated pipes, but the single-layer corrugated pipes cause certain abrasion on the surfaces of electric wires of the truck wire harness due to the fact that the inner walls of the corrugated pipes are caused by the structure and hardness of pipes, even some of the inner walls of the single-layer corrugated pipes wear through the outer surfaces of the electric wires to cause electric wire leakage or short circuit, so that the electric wires are caused to be burnt on fire, moreover, some wire harness protection products in the market of the truck in China can not meet the requirement of high and low temperature change environment and can still effectively protect the wire harness, meanwhile, the inner layers and the outer layers of the single-layer corrugated pipes for protecting the wire harness in China are all made of the.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a double-deck bellows is used in car wiring harness protection.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a double-deck bellows is used in protection of car wiring harness, its innovation point lies in: the corrugated pipe comprises an outer corrugated pipe and an inner corrugated pipe, wherein the inner corrugated pipe is arranged on the inner side of the outer corrugated pipe; the outer corrugated pipe is made of PPV0 material, and the hardness is 70D-80D; the inner corrugated pipe is made of TPVV0 elastomer material, and the hardness is 60-70A; the outer corrugated tube material and the inner corrugated tube material can be completely fused together.
Furthermore, the outer corrugated pipe and the inner corrugated pipe are respectively in different colors.
Further, the outer corrugated pipe is black.
Further, the inner corrugated pipe is blue or the natural color of the material.
Furthermore, the wall thickness of the outer corrugated pipe and the wall thickness of the inner corrugated pipe are both 0.2 mm.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has reasonable structure design and convenient use; the outer corrugated pipe has higher hardness, so that the abrasion of external factors and the extrusion of the corrugated pipe can be prevented; the inner corrugated pipe has lower hardness and is soft, so that the inner wall of the corrugated pipe can be prevented from wearing the surface skin of the wire harness wire; the outer corrugated pipe is made of a PPV0 material meeting the UL-94V 0 flame-retardant standard, the inner corrugated pipe is made of a TPVV0 elastomer material meeting the UL94-V0 flame-retardant standard, and when the surface of the electric wire catches fire, the electric wire has the function of preventing or retarding the continuous combustion of fire; the utility model can effectively protect the wire harness in the environment of-40 ℃ to 150 ℃ in turn due to the special effect of the material.

Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals:
1 outer bellows and 2 inner bellows.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, the double-layer corrugated pipe for protecting the automobile wire harness comprises an outer corrugated pipe 1 and an inner corrugated pipe 2, wherein the inner corrugated pipe 2 is arranged on the inner side of the outer corrugated pipe 1; the outer corrugated pipe 1 is made of PPV0 material, and the hardness is 70D-80D; the inner corrugated pipe 2 is made of TPVV0 elastomer material, and the hardness is 60A-70A; the outer corrugated tube material and the inner corrugated tube material can be completely fused together. Specifically, the outer corrugated pipe 1 is made of a PPV0 material meeting the flame retardant standard of UL-94V 0, the inner corrugated pipe 2 is made of a TPVV0 elastomer material meeting the flame retardant standard of UL94-V0, and when the surface of the electric wire catches fire, the electric wire has the function of preventing or retarding the continuous combustion of fire; the hardness of the outer corrugated pipe 1 is 70D-80D, and the outer corrugated pipe is hard, so that the outer corrugated pipe can be effectively prevented from being worn and extruded by external factors; the hardness of the inner corrugated pipe 2 is 60A-70A, the inner corrugated pipe is softer, and abrasion of the inner wall of the corrugated pipe to the surface of the wiring harness wire can be effectively prevented; due to the special effect of the material, the wire harness can still be effectively protected in an alternate environment of-40 ℃ to 150 ℃.
In this embodiment, the outer bellows 1 and the inner bellows 2 are different colors, respectively. The different colors are adopted for distinguishing, so that obvious visual impact is formed, and the installation is convenient.
In this embodiment, the outer bellows 1 is black, but not limited to black, and a suitable color may be selected according to the requirement.
