[0001] This utility model relates to the technical field of wire harness tape, and in particular to a highly flame-retardant automotive wire harness tape. Background Technology

[0002] Automotive wiring harness tape is specially designed for winding wiring harnesses in the automotive industry. It uses excellent base materials and high-quality synthetic rubber-based strong adhesive cloth tape, which has strong anti-aging ability, strong surface stain resistance and high temperature stability.

[0003] Current automotive wiring harness tapes have the following shortcomings:

[0004] 1) Existing tapes have smooth surfaces that come into contact with during wrapping. The limited adhesive area after wrapping results in the tape often coming unglued, which reduces the overall adhesive strength. Furthermore, most existing tapes are made of ordinary adhesive materials, which can melt and break at high temperatures, failing to provide flame-retardant protection for automotive wiring harnesses.

[0005] 2) Most existing tapes are flat strip structures with one-piece imaging. When the pulling force is too great, they often crack or break. After long-term use, the automotive wiring harness may come apart, which reduces the overall strength of the tape.

[0006] 3) Most existing tapes only have a single wrapping function. The wrapped automotive wiring harnesses will still bend randomly, and operators cannot shape and organize the wrapped automotive wiring harnesses, thus reducing the aesthetics of the wrapped automotive wiring harnesses. Utility Model Content

[0007] In view of the problems that existing tapes may melt and break at high temperatures and that automotive wiring harnesses may come apart after prolonged use, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a high flame retardant automotive wiring harness tape, which aims to improve the overall flame retardant and high temperature resistance properties of the tape, increase the strength of the tape after winding, and shape and finish the wound automotive wiring harness.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a high flame retardant automotive wiring harness tape. The high flame retardant automotive wiring harness tape includes a tape body 1, a flame retardant layer 11 disposed in the middle position inside the tape body 1, a heat resistant layer 12 disposed in the inner top of the tape body 1, a plurality of reinforcing grooves 10 evenly opened in the top of the tape body 1, a reinforcing component 2 that can increase the strength of the tape body 1 disposed in the middle position of the inner bottom of the tape body 1, and an adhesive layer 13 laid in the bottom of the tape body 1.

[0030] The flame retardant layer 11 is made of polyester film and is evenly laid on top of the tape body 1.

[0031] The heat-resistant layer 12 is made of high-temperature resistant silicone, and the heat-resistant layer 12 is evenly laid on top of the flame-retardant layer 11.

[0032] The reinforcing groove 10 is a semi-circular groove, and the reinforcing groove 10 is compatible with the adhesive layer 13.

[0033] The adhesive layer 13 is made of acrylic adhesive and is wrapped around the outside of the reinforcing component 2 of the tape body 1.

[0034] The tape body 1 is made of polyimide, and the bottom of the tape body 1 is fixedly bonded to the adhesive layer 13.

[0035] During use, the tape body 1 is torn apart from the tape as a whole. After tearing, the adhesive layer 13 is used to stick one end of the tape body 1 to the outside of the automotive wiring harness that needs to be wrapped. After sticking, it is wrapped evenly diagonally upwards. When wrapping, the adhesive layer 13 is stuck to the surface of the reinforcing groove 10. The groove of the reinforcing groove 10 increases the contact area of ​​the adhesive, making the tape more firmly adhered. After wrapping, the flame retardant layer 11 and the heat resistant layer 12 can be used to make the tape protect the automotive wiring harness from flame retardancy and high temperature.

[0036] Example 2

[0037] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a shaping strip 21 is fixedly provided inside the reinforcing component 2, and a reinforcing strip 20 is fixedly provided at the middle position of the bottom of the tape body 1.

[0038] The shaping strip 21 is made of iron, and the reinforcing strip 20 is made of rubber.

[0039] During use, when the tape body 1 is wrapped and adhered to the outside of the automotive wiring harness, the reinforcing strip 20 can improve the overall strength of the tape body 1, effectively preventing the tape from cracking or breaking, thereby improving the overall strength of the tape. Furthermore, the bending and shaping properties of the shaping strip 21 can make the automotive wiring harness more aesthetically pleasing after wrapping.

[0040] The remaining structure is the same as that in Example 1.

[0041] Based on embodiments 1-2, the working principle of this utility model is as follows: During use, the tape body 1 is torn from the tape as a whole. After tearing, one end of the tape body 1 is adhered to the outside of the automotive wiring harness to be wrapped using the adhesive layer 13. After adhesion, it is wrapped evenly upwards at an angle. During wrapping, the adhesive layer 13 is adhered to the surface of the reinforcing groove 10. The groove of the reinforcing groove 10 increases the contact area for adhesion. After wrapping, the properties of the flame-retardant layer 11 and the heat-resistant layer 12 allow the tape to provide flame-retardant and high-temperature protection for the automotive wiring harness. When the tape body 1 is wrapped and adhered to the outside of the automotive wiring harness, the reinforcing strip 20 can improve the overall strength of the tape body 1, effectively preventing cracking or breakage of the tape. Furthermore, the bending and shaping properties of the shaping strip 21 make the automotive wiring harness more aesthetically pleasing after wrapping.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
