[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1 Figure 2 As shown, a novel ultrasonic welding wire harness comprises a wire harness body 1 having a connecting shell 1 6 and a connecting shell 2 7 arranged on the outer sides of both ends thereof, a circular ring body 8 is fixedly connected to the outer sides of the connecting shell 1 6 and the connecting shell 2 7, a groove 9 is arranged on one side of the outer fixing plate 2 at the connection of two sets of adjacent wire harness bodies 1, the fixing plate 2 can be matched with the circular ring body 8 on the outer sides of the corresponding connecting shell 1 6 and the connecting shell 2 7 through the groove 9 to improve the connection stability and reliability of the two adjacent sets of wire harness bodies 1, the connecting shell 1 6 and the connecting shell 2 7 and the outer fixing plate 2 are all made of aluminum alloy, the aluminum alloy has light weight and good strength, good corrosion resistance and mechanical strength, is suitable for wire harness connection under various environmental conditions, and can effectively improve the strength of the connection of the wire harness body 1 and effectively prevent it from bending.

[0025] like Figure 3 Figure 4 As shown, the spiral harness body 1 can accommodate the thermal expansion of the harness during temperature changes, reduce the pressure on the harness body, and thus reduce the risk of aging and degradation of the harness. The thermal expansion tube 3 on the outside of the harness body can absorb the thermal expansion difference between the harness and the surrounding environment, reduce the tensile or compressive force on the harness body 1, and further protect the integrity and service life of the harness. The thermal expansion tube 3 is a special tubular structure made of a heat-sensitive material that can change in shape and size when the temperature changes. The thermal expansion tube 3 can expand when the temperature rises and contract when the temperature drops, and can automatically adjust according to the temperature change. The length or shape of the spiral harness body 1 can reduce thermal stress and strain. The protective outer ring 4 between adjacent thermal expansion tubes 3 is composed of a waterproof layer 10, an anti-corrosion layer 11, a reinforcement layer 12 and a steel wire 13. The anti-corrosion layer 11 and the outer waterproof layer 10 can effectively improve the corrosion resistance and waterproofness of the protective outer ring 4. The reinforcement layer 12 inside the anti-corrosion layer 11 and the steel wire 13 between the waterproof layer 10 and the anti-corrosion layer 11 can improve the use strength of the protective outer ring 4. The thermal expansion tube 3 is generally treated with galvanizing or fire-retardant coating for corrosion resistance. It has anti-oxidation, rust-proof, corrosion-resistant and other properties, and can also play a role in waterproofing and fire prevention.

[0026] Working principle: A connecting shell 1 6 and a connecting shell 2 7 are provided on the outer sides of both ends of the wiring harness body 1, and a circular ring body 8 is fixedly connected to the outer sides of the connecting shell 1 6 and the connecting shell 2 7. A groove 9 is provided on one side of the outer fixing plate 2 at the connection of the two sets of adjacent wiring harness bodies 1, and the fixing plate 2 can fit with the circular ring body 8 on the outer side of the corresponding connecting shell 1 6 and the connecting shell 2 7 through the groove 9. The spiral wiring harness body 1 can cooperate with the outer thermal expansion tube 3 to accommodate the thermal expansion of the wiring harness during temperature changes, reducing the tensile or compressive force on the wiring harness body 1. The thermal expansion tube 3 can expand when the temperature rises and contract when the temperature drops. The length or shape of the spiral wiring harness body 1 can be automatically adjusted according to temperature changes. The anti-corrosion layer 11 and the outer waterproof layer 10 can effectively improve the corrosion resistance and waterproofness of the protective outer ring 4. The inner reinforcing layer 12 of the anti-corrosion layer 11 and the steel wire 13 between the waterproof layer 10 and the anti-corrosion layer 11 can improve the use strength of the protective outer ring 4.
