Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an environment-resistant wire harness. Background Art

[0002] A wiring harness is a collection of multiple wires bundled together, usually composed of wires, terminals, connectors and accessories (such as magnetic rings, tapes, cable ties and labels). It is a carrier of input and output currents and signals and is widely used in the automotive industry, power industry, communications industry, aerospace and military industry, and medical industry.

[0003] At present, in industries such as electricity, wiring harnesses need to withstand environmental factors such as high voltage, high temperature and severe weather. Traditional wiring harnesses usually adopt a structure in which an outer sheath is wrapped around multiple wires. In harsh outdoor environments, after the wiring harness is pulled or bent by external force, there is great wear and tear between the multiple internal wires, which reduces the durability of the wiring harness. Therefore, the present application provides an environmentally resistant wiring harness to meet the needs. Utility Model Content

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an environment-resistant wire harness, including an outer sheath 1, wherein a grid 2 is arranged inside the outer sheath 1, and the grid 2 divides the inner space of the outer sheath 1 into a plurality of wire arrangement channels 6, and a plurality of wires 3 are inserted into each wire arrangement channel 6. By arranging the grid 2 inside the outer sheath 1, the inner space of the outer sheath 1 is divided into a plurality of wire arrangement channels 6, which can provide for the classified transmission and arrangement of the plurality of wires 3, thereby avoiding the problem that the plurality of wires 3 are easily wrapped together and the wires 3 are easily accelerated to wear due to the bending and pulling of the wire harness. A shielding sheath 4 is arranged inside the outer sheath 1, and the shielding sheath 4 is arranged in contact with the inner wall of the outer sheath 1. The material of the shielding sheath 4 is one of a metal braided mesh and a metal foil. By arranging the shielding sheath 4 made of a metal braided mesh or a metal foil in contact with the inner wall of the outer sheath 1, it is possible to effectively shield external electromagnetic interference and radio frequency interference, and protect the stable transmission of the signal inside the wire harness.

[0032] like Figures 1 to 3 As shown, the grid 2 includes a central hose 7 centrally inserted into the outer sheath 1 and a partition sheet 9 radially arranged between the outer wall of the central hose 7 and the inner wall of the shielding sheath 4. A wiring channel 6 is formed between the outer wall of the central hose 7, two adjacent partition sheets 9 and the inner wall of the shielding sheath 4.

[0033] like Figures 1 to 4 As shown, a bushing 5 is inserted into the wiring channel 6, and the bushing 5 is in contact with the inner wall of the shielding jacket 4 and two adjacent separators 9. The wire 3 is inserted into the bushing 5. The bushing 5 is made of one of polypropylene and polyethylene. By inserting the bushing 5 into the wiring channel 6 and inserting the wire 3 into the bushing 5, the wire 3 can be further protected and the compression resistance of the wire harness can be improved. A groove 11 is provided on the side of the bushing 5 facing the central hose 7, which is conducive to the release of stress.

[0034] like Figures 1 to 4As shown, a first reinforcing rib 8 is inserted into the center hose 7, and a second reinforcing rib 12 is inserted into the bushing 5. The first reinforcing rib 8 and the second reinforcing rib 12 are made of polyamide. By inserting the first reinforcing rib 8 and the second reinforcing rib 12 made of polyamide into the center hose 7 and the bushing 5 respectively, the tensile strength of the wiring harness is improved.

By using the outer sheath 1 made of PVC, PU or TPE, the wear resistance, weather resistance, corrosion resistance and other properties of the wiring harness are improved.

[0036] The working principle of the technical solution provided by the utility model is as follows:

[0037] By setting a shielding sheath 4 made of a metal braided mesh or a metal foil in close contact with the inner wall of the outer sheath 1, it is possible to effectively shield external electromagnetic interference and radio frequency interference, and protect the stable transmission of the signal inside the wiring harness. By setting a grid 2 composed of a central hose 7 and a separator 9 in the outer sheath 1, the inner part of the outer sheath 1 is divided into a plurality of wiring channels 6 by the central hose 7 and the separator 9, so that a plurality of wires 3 can be classified, sent and arranged, and the problem of accelerated wear of the wires 3 due to bending and pulling of the wiring harness when the plurality of wires 3 are wrapped together is avoided. By passing a bushing 5 through the wiring channel 6 and passing the wire 3 through the bushing 5, further protection can be provided to the wire 3, and the compression resistance of the wiring harness is improved. By respectively passing a first reinforcing rib 8 and a second reinforcing rib 12 made of polyamide through the central hose 7 and the bushing 5, the tensile resistance of the wiring harness is improved. By adopting an outer sheath 1 made of PVC, PU or TPE, the wear resistance, weather resistance, corrosion resistance and other properties of the wiring harness are improved, and it is more suitable for harsh environments.
