The automotive wiring harness is distributed in various locations inside the car and is used to form the overall line operation of the car.

[0003] With the development of science and technology, many new applications have appeared in automobiles, so the use of wiring harnesses has gradually increased. However, the space inside the car body is limited. When the wiring harness is laid inside the car body, it is inevitable to encounter turning and twisting areas. Long-term use can easily cause damage to the wiring harness, which is not conducive to circuit operation. When a fault occurs, the wiring harness may burn and explode, which is not conducive to the safety of the vehicle and the driver. The existing anti-bending measures for the wiring harness are generally to enhance the strength of the outer skin. However, after the strength of the outer skin is improved, it cannot be laid in a tortuous manner. After being made into an arc surface by external pressure, the wire skin is easy to break after long-term use, which is not conducive to the safe use of the wiring harness. Utility Model Content

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 , Figure 2 As shown, the utility model is a bending-resistant new energy vehicle wiring harness, including a wiring harness body 1, which is used for power supply and communication in the car. A wiring harness protective cover 2 is arranged on the wiring harness body 1, and the wiring harness protective cover 2 is used to improve the bending resistance and pressure resistance of the wiring harness body 1. Specifically, the wiring harness protective cover 2 is composed of a rubber cover 3 and a pressure-resistant cover 4. The wiring harness protective cover 2 is sleeved on the wiring harness body 1 when in use, wherein the rubber cover 3 is provided with multiple layers, which are a first braided layer 31, a second braided layer 32 and a protective layer 33 arranged in sequence from the inside to the outside. When in use, the first braided layer 31 is coated on the wiring harness body 1, and the second braided layer 32 is arranged outside the first braided layer 31, and the protective layer 33 is coated on the second braided layer 32. The first braided layer 31 is made of softer fiber braided wire for protecting the wiring harness body 1, and the second braided layer 32 is made of copper wire with shielding function for braiding, which is used to improve the shielding effect of the wiring harness body 1 and improve the communication performance. The protective layer 33 improves the bending resistance of the wiring harness body 1.

[0018] Among them, Figure 2As shown, the protective layer 33 is composed of a rubber strip 331 and a wire skin layer 332. The rubber strip 331 is in the shape of a long strip, and its length is equivalent to the length of the wire harness body 1. The rubber strip 331 is made of nitrile rubber. The rubber strip 331 made of this material is not easy to be bent, has high strength, and also has a certain elasticity. A plurality of rubber strips 331 are arranged at intervals on the outer surface of the second braided layer 32. In order to make the rubber strip 331 firmly set on the second braided layer 32, glue is used to adhere the two. The number of rubber strips 331 set is at least four, which are arranged opposite to each other in pairs. The shape of the rubber strip 331 is one of a trapezoid, a circle, and a rectangle. Finally, The wire skin layer 332 is wrapped around the rubber strip 331, and the rubber strip 331, the second braided layer 32, the first braided layer 31, and the wire harness body 1 are all wrapped in the wire skin layer 332. The wire skin layer 332 is a rubber insulation layer. The wire skin layer 332 is made of silicone rubber. The wire skin layer 332 is in a tubular shape with a wall thickness of 0.3-2mm. When the wire harness body 1 is set at a turning or bending position of the vehicle body, it can be bent to a certain arc, but due to the bending resistance of the rubber strip 331, it cannot be bent into a larger arc or folded in half, so that the wire harness body 1 located in the protective layer 33 is not damaged by bending or extrusion, which is beneficial to the safety of the wire harness body 1.

[0019] like Figure 3 The anti-pressure sleeve 4 is detachably arranged on the wire skin layer 332. Specifically, the anti-pressure sleeve 4 is used or not according to the specific application scenario in the vehicle body. The anti-pressure sleeve 4 is a non-essential structure. The anti-pressure sleeve 4 is integrally formed by an anti-pressure plate 41 and an elastic member 42. The elastic member 42 is provided with two rows, which are respectively arranged at the two ends of the anti-pressure plate 41, and the elastic member 42 is convexly arranged upward, and an opening is formed on the top between the two rows of elastic members 42. The opening is used for the insertion and removal of the wiring harness body 1, and can support and limit the wiring harness body 1. The anti-pressure sleeve 4 is made of a rubber material with a micro-elastic property, which can increase the compression resistance of the wiring harness when used. The coordinated use of the rubber sleeve 3 and the anti-pressure sleeve 4 greatly enhances the bending resistance and compression resistance of the wiring harness body 1, which is beneficial to the safe use of the wiring harness.
