[0021] A wire harness wrapping structure, as shown in Figs. 1-3 The wire harness 1 is provided with at least one area to be closed 11, and the wrapping structure 2 is arranged on the wire harness 1 and wraps and closes the area to be closed 11. The wrapping structure 2 comprises a high-temperature-resistant layer 21 arranged around the outside of the area to be closed 11 and at least two fixing members 22 for fixing the high-temperature-resistant layer 21. The two ends of the high-temperature-resistant layer 21 extend to the wire harness 1, and the fixing members 22 are arranged on the outside of the opposite ends of the high-temperature-resistant layer 21 to fix the two ends of the high-temperature-resistant layer 21 on the wire harness 1.

[0022] The conductor 12 of the wire harness 1 is made of copper or aluminum and is covered with an insulating layer 13 to provide electrical isolation and mechanical protection. The high-temperature-resistant layer 21 is a single-layer or multi-layer high-temperature-resistant cloth 4, and the fixing member 22 is a cable tie or a metal clamp. In use, the insulating layer at the end of the wire harness 1 is first peeled off to become the area to be closed 11. The area to be closed 11 is the conductor 12 or the conductor 12 covered with a shielding layer. The high-temperature-resistant cloth 4 is laid and wrapped around the area to be closed 11, and the fixing member 22 is fixed at least one on the outer periphery of the area to be closed 11 and at least one on the outer periphery of the insulating layer 13 to fix the wrapping structure 2 on the wire harness. The high-temperature-resistant layer 21 can effectively block external high temperature, prevent the wire harness insulating layer 13 from melting or the conductor 12 from oxidizing, and prolong the service life of the wire harness. The high-temperature-resistant layer 21 is fastened by the wrapping and the fixing member 22 to form a gapless closed structure, which prevents water vapor, oil stains, and dust from entering the area to be closed and meets the protection requirements.

[0023] In some embodiments, the high-temperature-resistant layer 21 is composed of at least one layer of high-temperature-resistant cloth 4, and the fixing member 22 is a cable tie 3, as shown in Fig. 3 The high-temperature-resistant cloth 4 is wrapped on the outside of the area to be closed 11, and the opposite ends of the high-temperature-resistant cloth 4 are fixed by the cable tie 3. The two ends of the high-temperature-resistant cloth 4 extend to the normal section of the wire harness by at least 20 mm and are wrapped in the same direction to ensure that there is no wrinkle.

[0024] Further, the high-temperature-resistant cloth 4 is provided with multiple layers, and a channel for passing the cable tie 3 is formed in the multiple layers of high-temperature-resistant cloth 4. The direction of the channel is consistent with the wrapping direction of the high-temperature-resistant cloth 4. The cable tie 3 is passed into the channel of the multiple layers of high-temperature-resistant cloth 4 and is tightened to be fixed on the wire harness 1.

[0025] Further, the multiple layers of high-temperature-resistant cloth 4 are connected by adhesion. Thus, the multiple high-temperature-resistant cloths 4 form a whole, which is convenient for wrapping the wire harness 1.

[0026] Further, the cable tie 3 is passed and preset in the channel. The preset cable tie 3 makes the wrapping structure 2 a whole, which is convenient for automatic production.

[0027] In some embodiments, the cable ties 3 include a head 31 and a tail 32, as shown. Fig. 3 In some embodiments, the head 31 and the tail 32 of different cable ties 3 are located on the same side of the high-temperature-resistant cloth 4. By uniformly arranging the head 31 and the tail 32 of different cable ties 3 on the same side of the high-temperature-resistant cloth 4, the installation and disassembly operations are simplified, and quick maintenance is facilitated.

[0028] In some embodiments, the wire harness 1 includes a conductor 12, a shielding layer, and an insulating layer 13 arranged in sequence from inside to outside. The shielding layer effectively guarantees the electrical transmission stability, electromagnetic shielding performance, and external environment isolation capability of the wire harness, and improves the reliability of the wire harness 1 transmission.

[0029] Further, the insulating layer 13 is provided with a groove, and the fixing member 22 is at least partially located in the groove. The groove design of the insulating layer 13 makes the fixing member 22 partially embedded therein, preventing the fixing member 22 from being displaced due to vibration or external force, and enhancing the mechanical stability.

[0030] In some embodiments, the high-temperature-resistant cloth 4 is a PP woven cloth or a PET woven cloth or an aluminum foil cloth. Using a PP woven cloth, a PET woven cloth, or an aluminum foil cloth as a high-temperature-resistant layer can ensure that the overall structure meets the requirements of lightweight and chemical corrosion resistance.

[0031] In some embodiments, the material of the fixing member 22 is PA66 or PA46 or metal.
