[0025] See also Figure 1-2 As shown, the present embodiment discloses a radiation-proof and high-temperature-resistant wiring harness for automobiles, comprising: a wiring harness body 1, a flannel tape and an adhesive tape; the flannel tape is wound around the outside of the wiring harness body 1 to form a flannel layer 2; the adhesive tape is wound around the flannel tape and the outside of the wiring harness body 1 to form an adhesive tape layer 3; the adhesive tape is composited with glass fiber cloth and aluminum foil, the adhesive side of the adhesive tape is attached with silicone adhesive, and the adhesive side of the adhesive tape is adhered to the flannel tape; the thickness of the adhesive tape is greater than or equal to 0.18 mm and less than or equal to 0.25 mm; the width of the adhesive tape is greater than or equal to 18 mm and less than or equal to 20 mm.

[0026] The radiation-proof and high-temperature-resistant wiring harness for automobiles of this embodiment adopts a velvet tape to wrap the wiring harness body 1, so that the high-temperature resistance performance of the wiring harness is improved to a certain extent; a glass fiber cloth composite aluminum foil tape is wound on the side of the velvet tape away from the wiring harness body 1, so that the wiring harness has radiation protection performance, reduces the influence of electromagnetic radiation on the wires, and enhances the high-temperature resistance and flame retardancy of the wiring harness; the silicone adhesive on the tape is corrosion-resistant and can maintain stability in a high-temperature environment, so that the tape is resistant to high temperatures and is not easy to separate from the velvet tape; the width and thickness of the tape are both small, which is suitable for the winding of automobile wiring harnesses, reduces the space occupied by the wiring harness, is conducive to the arrangement and arrangement of the wiring harness in a limited space, and helps to dissipate heat from the wiring harness body 1, prevents excessive heat accumulation in the tape layer 3, and improves the adaptability of the wiring harness in a high-temperature environment; the wiring harness is doubly protected by the velvet tape and the tape, which improves the overall performance of the wires and improves the safety and reliability of the wiring harness in automobiles.

[0027] In one embodiment, the adhesive tape layer 3 includes: two horizontal portions 31; the two horizontal portions 31 are formed by the adhesive tape horizontally wrapped around the two ends of the flannel layer 2; the horizontal portion 31 covers the gap between the flannel layer 2 and the wiring harness body 1. In practical applications, the flannel tape is wrapped around the section of the wiring harness body 1 that needs to be protected, and the adhesive tape layer 3 completely wraps the flannel layer 2 and extends beyond the two ends of the flannel layer 2, that is, the adhesive tape layer 3 wraps the flannel tape along the wiring harness body 1 and the wiring harness body 1 near the two ends of the flannel layer 2, so that the adhesion between the flannel tape and the wiring harness body 1 is more stable, and the damage rate of the flannel tape is reduced, and the heat resistance of the flannel tape is improved, thereby providing excellent radiation resistance, heat resistance and flame retardant protection for the wiring harness body 1. The horizontal portion 31 is sleeved in a cylindrical shape and tightly wrapped around the wiring harness body 1 and the flannel tape. The horizontal winding prevents the two ends of the adhesive tape layer from opening and is not easy to warp, thereby ensuring the adhesion stability of the adhesive tape, thereby improving the service life and safety of the wiring harness body 1.

[0028] Preferably, the difference in length between the adhesive tape layer 3 and the flannel layer 2 along the length direction of the harness body 1 is 2-6 mm. The length of the horizontal portion 31 covering the harness body 1 is 1-3 mm, which ensures the stability of the flannel tape and the adhesive tape.

[0029] In one embodiment, the adhesive tape layer 3 includes: a spiral portion 32; the spiral portion 32 is formed by the adhesive tape spirally wound between the two ends of the flannel layer 2. The adhesive tape is spirally wound around the flannel layer 2 and the wiring harness body 1, and the winding method is simple and can be flexibly adapted to the surface of the wiring harness body 1 or the flannel layer 2, preventing the adhesive tape and the flannel tape from loosening, and can firmly and tightly wind the flannel tape to prevent external high temperature and radiation from corroding the wires.

[0030] In one embodiment, adjacent tapes on the spiral portion 32 overlap each other, and the overlapping width is 0.25-0.5 times the width of the tape. During the spiral winding process, each layer of the tape covers 1 / 4 to 1 / 2 of the area of ​​the previous layer, avoiding gaps between adjacent tapes and failing to achieve good protection performance.

[0031] In one embodiment, the horizontal portion 31 and the spiral portion 32 are an integrated structure. When the adhesive tape is wound, it is first wound horizontally, then stacked and wound obliquely, and finally wound horizontally. The winding process is uninterrupted, ensuring that there is no gap in the winding of the adhesive tape, so that the adhesive tape layer 3 plays the role of heat insulation, flame retardancy and all-round radiation resistance.

[0032] Preferably, the thickness of the tape is 0.2 mm, and the width of the tape is 19 mm. The tape thickness is small, which is easy to dissipate heat from the wiring harness body 1 and to wind the tape; the tape width is small, which is suitable for winding small items such as automotive wiring harnesses.

[0033] Preferably, the adhesive tape is TESA 88780 tape. TESA 88780 tape has heat insulation, flame retardancy and heat reflection properties, and can withstand temperatures of -40°C to 250°C, conforms to ISO 3795 Class A and LV312 standards, and is suitable for protecting wiring harnesses around automobile engine compartments and exhaust pipes.

[0034] In one embodiment, the flannel tape is made of PET material. PET has wear resistance, high temperature resistance, chemical stability, insulation, flexibility and tear resistance, making the flannel tape wear-resistant, durable and high temperature resistant. The flannel tape is wrapped around the wiring harness body 1, making the wiring harness body 1 corrosion-resistant and high temperature resistant. At the same time, it serves as a buffer between the adhesive tape and the wiring harness body 1, preventing the wiring harness body 1 from being difficult to maintain a preset curved or straight shape, so that the adhesive tape can easily adapt to the irregular shape of the wiring harness body 1.

[0035] In one embodiment, the adhesive side of the flannel tape is attached with natural rubber, which has strong adhesion, is renewable, and has certain cold and heat resistance, so that the flannel tape is not easy to separate from the wiring harness body 1 .

[0036] Preferably, the thickness of the flannel belt is 0.28 mm and the width is 19 mm. The thickness and width of the flannel belt are both small, which reduces the difficulty of winding the flannel belt and is suitable for winding small items such as automotive wiring harnesses.

[0037] Preferably, the flannel tape is TESA 51608 tape. TESA 51608 tape has the characteristics of high flexibility and good noise reduction performance, a breaking elongation of 20%, a tensile strength of 40N / cm, a maximum temperature tolerance of 105°C, a minimum temperature tolerance of -40°C, and meets the LV312 standard, and is suitable for protecting wiring harnesses around automobile engine compartments and exhaust pipes.

[0038] The present embodiment is a radiation-proof and high-temperature-resistant wiring harness for automobiles. A velvet tape is used to wrap the wiring harness body, so that the high-temperature resistance of the wiring harness is improved to a certain extent; a glass fiber cloth composite aluminum foil tape is wrapped around the side of the velvet tape away from the wiring harness body, so that the wiring harness has radiation protection performance, reduces the influence of electromagnetic radiation on the wires, and enhances the high-temperature resistance and flame retardancy of the wiring harness; the silicone adhesive on the tape is corrosion-resistant and can maintain stability in a high-temperature environment, so that the tape is resistant to high temperatures and is not easy to separate from the velvet tape; the width and thickness of the tape are both small, which is suitable for the winding of automobile wiring harnesses, reduces the space occupied by the wiring harness, is conducive to the arrangement and arrangement of the wiring harness in a limited space, and helps to dissipate the heat of the wiring harness body, prevents excessive heat accumulation in the tape layer, and improves the adaptability of the wiring harness in a high-temperature environment; the wiring harness is doubly protected by the velvet tape and the tape, thereby improving the overall performance of the wires and improving the safety and reliability of the wiring harness in automobiles.
