Description

Light wire harness with good wear resistance for new energy automobile Technical Field The utility model belongs to the technical field of automobile wire harnesses, and particularly relates to a light wire harness with good wear resistance for a new energy automobile. Background With the improvement of the market share of new energy electric vehicles, the new energy automobiles in developed countries are highly popularized, and most of automobile manufacturers in China are expanding the production and sales of the new energy automobiles. The hundred kilometers of energy consumption cost of the electric car is still only half of that of the gasoline facing the current price of crude oil. In China, this price ratio is more exaggerated, although crude oil prices are in constant decline. The fundamental advantages of new energy are being reduced, but the basic facts that the electricity price is lower than the oil price are difficult to change in the middle period, the potential of the electric car is still obvious, the complete car wiring harness is an important part of the new energy car, the existing wiring harness is generally covered by an outer rubber insulating sleeve, the existing wiring harness is easy to damage, the shielding effect is also not durable, the overall wear resistance is lower, and meanwhile, the outer insulating sleeve is thick and heavy, which is contrary to the current mainstream lightweight design, so that the market application is affected. Therefore, a light-weight wire harness for new energy automobiles with good wear resistance is urgently needed to be studied. Disclosure of utility model In view of the above, the technical problem to be solved by the utility model is to provide a light-weight wire harness with good wear resistance for a new energy automobile, which is used for avoiding the trouble that the conventional automobile wire harness is poor in wear resistance and easy to wear. In order to solve the technical problems, the utility model discloses a light wire harness with good wear resistance for a new energy automobile, which comprises the following components: A wire core; The honeycomb duct is formed by braiding aluminum-magnesium alloy wires, and the inner wall of the honeycomb duct is provided with an insulating film for coating the wire core; the polyurethane guide sleeve is sleeved on the honeycomb duct, the outer wall of the polyurethane guide sleeve is provided with a spiral reinforcing rib and a plurality of holes, the diameter of the spiral reinforcing rib is 0.1mm, and the holes are formed through puncture and are spaced from the spiral reinforcing rib; The thickness of the fluorosilicone resin jacket is 0.8-1.2mm, and the copper mesh wire layer is embedded in the inner wall of the fluorosilicone resin jacket; wherein, the flame retardant fiber is filled between the polyurethane guide sleeve and the fluorosilicone resin jacket. According to an embodiment of the present utility model, the surface of the polyurethane guide sleeve is coated with a silicon carbide coating. According to an embodiment of the present utility model, the thickness of the polyurethane guide sleeve is 1mm. According to an embodiment of the present utility model, at least 6 spiral reinforcing ribs are provided. According to an embodiment of the present utility model, the openings are formed by piercing with a 0.2mm puncture needle, and the adjacent spacing is at least 2.5mm. Compared with the prior art, the utility model can obtain the following technical effects: The honeycomb guide tube is matched with the insulating film to cover the inner wire core, so that the shielding effect is enhanced, meanwhile, the lightweight design is realized, the outer wall of the polyurethane guide sleeve is provided with spiral reinforcing ribs to improve the strength, the puncture holes are formed to enhance the toughness and the pressure is reduced, and the outer fluorosilicone resin jacket is used for enhancing the outer protection and improving the wear resistance.
