Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wiring harnesses, and in particular relates to an anti-vibration and flame-retardant automobile wiring harness. Background Art

[0002] One of the key technologies of automotive wiring harnesses is the research and improvement of flame retardant and seismic performance. Automotive wiring harnesses are mainly used to protect automotive cables. During the driving process of the car, the ups and downs are relatively large and the driving time is long, so the heat generated by the relevant parts of the car is large, thereby increasing the temperature around the automotive parts. Since there are many automotive wiring harnesses connected to the automotive parts, the automotive wiring harnesses will soften when encountering high temperatures, and in more serious cases, they will catch fire, eventually causing the automotive wiring harness to short-circuit, thus causing serious impact on the driving of the car. However, the existing technology does not deeply study the flame retardancy and seismic performance of automotive wiring harness materials, and ordinary automotive wiring harness materials are far from meeting the requirements. Utility Model Content

[0003] In view of this, the technical problem to be solved by the utility model is to provide a shock-resistant and flame-retardant automobile wiring harness, so as to avoid the trouble of poor shock resistance and flame retardancy of the previous automobile wiring harness.

[0005] Multiple wire harness cores;

[0006] An inner flame retardant sleeve is provided with a plurality of wire harness cores, and the outer wall of the inner flame retardant sleeve has a grid groove;

[0007] A TPV buffer liner coated on the inner flame retardant sleeve, wherein the inner wall of the TPV buffer liner has a grid protrusion fitted into the grid groove;

[0008] Multiple anti-seismic rings are arranged on the outer surface of the TPV buffer liner, and the anti-seismic rings are provided with arc-shaped notches at equal intervals;

[0009] An outer sheath mounted on the TPV buffer liner.

[0010] According to an embodiment of the utility model, flame-retardant fibers are filled between the inner flame-retardant sleeve and the plurality of wire harness cores.

[0011] According to an embodiment of the utility model, the depth of the grid groove is 1 mm, and the groove opening expands outward and has an outward slope.

[0012] According to an embodiment of the utility model, the height of the anti-vibration ring is 1 mm, and at least 4 arc-shaped notches are provided.

[0013] According to one embodiment of the utility model, the thickness of the TPV buffer liner is 0.8-1 mm.

[0014] Compared with the prior art, the utility model can obtain the following technical effects:

[0015] The wire harness core is set through an inner flame-retardant sleeve to improve flame retardancy, and the TPV buffer lining is covered with a grid on the outside to enhance buffering. Finally, an anti-vibration ring is set on the outside of the TPV buffer lining to further reduce shock and improve stability. The outer sheath enhances wear resistance and extends service life.

[0021] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Please refer to Figure 1 , Figure 1 It is a schematic diagram of a seismic and flame-retardant automobile wiring harness according to an embodiment of the utility model.

[0023] As shown in the figure, a seismic-resistant and flame-retardant automotive wiring harness includes: a plurality of wiring harness cores 10; an inner flame-retardant sleeve 20 on which the plurality of wiring harness cores 10 are sleeved, the outer wall of the inner flame-retardant sleeve 20 having a grid groove; a TPV buffer liner 30 wrapped around the inner flame-retardant sleeve 20, the inner wall of the TPV buffer liner 30 having a grid protrusion that fits into the grid groove; a plurality of seismic-resistant rings 31 arranged on the outer surface of the TPV buffer liner 30, the seismic-resistant rings 31 having arc-shaped notches equidistantly arranged; and an outer sheath 40 sleeved on the TPV buffer liner 30.

[0024] In one embodiment of the utility model, the wiring harness core 10 is composed of a conductor core covered with an insulating sheath, which is interlaced together according to specifications and fixed in an inner flame retardant sleeve 20, wherein flame retardant fibers 50 are filled between the inner flame retardant sleeve 20 and the plurality of wiring harness cores 10, which, on the one hand, enhance the buffering between the wiring harness cores 10, and on the other hand, cooperate with the external inner flame retardant sleeve 20 and the flame retardant fibers 50 to achieve high-strength flame retardant performance.

[0025] The outer wall of the inner flame retardant sleeve 20 is provided with a grid groove for positioning and guiding, the depth of the grid groove is 1mm, and the notch is expanded outward with an outward slope. Correspondingly, the TPV buffer liner 30 covers the inner flame retardant sleeve 20, and it has a grid protrusion that fits the grid groove. The two match each other, enhancing the buffering after positioning and improving the shock absorption effect. In addition, the outer wall of the TPV buffer liner 30 is also provided with multiple anti-seismic rings 31, which are used to cooperate with the outer sheath 40 to further enhance the anti-seismic effect. The outer sheath 40 enhances wear resistance and improves service life.

[0026] Preferably, the height of the anti-seismic ring 31 is 1 mm, and a plurality of arc-shaped notches are provided on the outer ring, which can resist seismicity on the one hand and reduce the contact area and improve the cushioning performance on the other hand. There are at least 4 arc-shaped notches, which are evenly and equidistantly provided and the force is stable.

[0027] In addition, the TPV buffer liner 30 has a thickness of 0.8-1 mm, which ensures a sufficient buffering effect.

[0028] In summary, the utility model improves the flame retardancy by enclosing the wiring harness core 10 with the inner flame retardant sleeve 20, and strengthens the buffering by covering the TPV buffer liner 30 with a grid on the outside, and finally continues to set the anti-vibration ring 31 on the outside of the TPV buffer liner 30 to further reduce shock and improve stability. The outer sheath 40 enhances wear resistance and prolongs service life.
