[0002] With the rapid development of the automobile industry, the reliability of automobile wiring harnesses has received more and more attention. At present, automobile wiring harnesses are mainly composed of wires, connectors, insulation sleeves and sheaths. During the operation of the car, the wiring harness needs to withstand the influence of high temperature, and it is easy to have short circuits, open circuits and other faults, which affect the normal operation of the car, so a high temperature resistant automobile wiring harness is needed.

[0003] At present, the common way to fix the wire harness is often to use binding and locking, which may cause the line to loosen during vehicle operation or even short circuit.

In addition, the bundling method may also cause additional pressure on the wire harness, causing the wire harness to wear or damage, further affecting its service life. If the protective cover cannot be quickly restored to its original state after being squeezed, it is likely to affect the information transmission of the wire harness core.

[0004] Therefore, it is necessary to provide a high temperature resistant automotive wiring harness to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a high temperature resistant automotive wiring harness provided by the utility model; Figure 2 for Figure 1 A schematic cross-sectional view of the bundle shown; Figure 3 for Figure 1The schematic diagram of the structure of the debugging ring is shown. A high temperature resistant automotive wiring harness comprises: a wiring harness 1, a clamping ring groove 2 is provided on the surface of the wiring harness 1, clamping baffles 3 are fixedly connected on both sides of the clamping ring groove 2, elastic sheets 4 are fixedly connected to the clamping baffles 3 on both sides, clamping sheets 5 are fixedly connected to the elastic sheets 4, buffer pads 6 are fixedly connected to the clamping sheets 5, a debugging ring 7 is provided on the surface of the elastic sheet 4, an anti-skid groove 8 is provided on the outer surface of the debugging ring 7, an inner ring rubber 9 is fixedly connected inside the debugging ring 7, an elastic bump 10 is fixedly connected on the surface of the inner ring rubber 9, and a recovery layer 11 is provided inside the wiring harness 1. The wiring harness avoids the risk of short circuit, reduces vehicle failures caused by wiring harness problems, and improves driving safety.

[0020] The material of the buffer pad 6 is rubber, and the material of the recovery layer 11 is silicone. When the protective cover is squeezed, the recovery layer 11 can quickly return to its original state, thereby protecting the main wiring harness from damage.

[0021] The outer surface of the wire harness 1 is provided with an outer skin 12, the outer surface of the outer skin 12 is provided with a wear-resistant layer 13, and the inner surface of the outer skin 12 is provided with a heat-resistant layer 14. The wear-resistant layer 13 and the heat-resistant layer 14 can improve the wear resistance and heat resistance of the outer skin.

[0022] The material of the wear-resistant layer 13 is polyolefin, and the material of the heat-resistant layer 14 is ceramic fiber. Polyolefin has good wear resistance and chemical corrosion resistance, and ceramic fiber has excellent thermal insulation performance and can effectively block heat.

[0023] A waterproof layer 15 is provided inside the wiring harness 1. The waterproof layer 15 is made of chloroprene rubber, which has good waterproof, oil-resistant and chemical-resistant properties.

[0024] A flame retardant layer 16 is provided inside the wiring harness 1. The material of the flame retardant layer 16 is flame retardant cross-linked polyethylene. A wiring harness inner core 17 is provided inside the wiring harness 1. The cross-linked polyethylene itself has certain flame retardancy. Its flame retardancy can be further improved by adding flame retardants.

[0025] The working principle of a high temperature resistant automobile wiring harness provided by the utility model is as follows:

[0026] When the wire harness 1 is fixedly installed, the clamping ring groove 2 is slid according to the installation position. When it slides to the specified position, the debugging ring 7 is pushed to make the clamping piece 5 on the elastic piece 4 tightly adhere to the surface of the wire harness 1, so that the clamping ring groove 2 can be tightly locked on the surface of the wire harness 1. At the same time, due to the buffering of the buffer pad 6, the outer skin of the surface of the wire harness 1 will not be damaged when the wire harness 1 is clamped. At this time, the force only needs to act on the clamping ring groove 2 to complete the fixation of the wire harness 1. At the same time, when the outer surface of the wire harness 1 expands due to heat, the elastic protrusion 10 on the inner ring rubber 9 is elastic and can withstand extrusion within a certain range. When the wire harness 1 is squeezed, the recovery layer 11 can help the wire harness 1 quickly return to its original state.

[0027] Compared with the related art, the high temperature resistant automotive wiring harness provided by the utility model has the following beneficial effects:

[0028] The design of the clamping mechanism can effectively avoid the loosening and short circuit problems of the wire harness 1, ensure that the wire harness 1 can still maintain a stable connection in a high temperature environment, and the force acts on the clamping ring groove 2 during fixed installation, which can reduce most of the pressure and further improve its service life. The clamping ring groove 2 can slide on the outer surface of the wire harness 1 to adapt to fixed installation in various positions. The recovery layer 11 arranged inside can quickly return to its original state after being squeezed, reduce damage to the wire harness 1, extend the service life of the wire harness 1, and enhance the durability of the wire harness.
