[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) punched from copper material, which is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component connecting the circuit with a wiring harness. The interior of the car is full of intricate wires and connectors, forming a complex electrical system network. As the core component of this network, automotive wiring harness cables undertake the important task of transmitting power, signals and control information, and play a vital role in the safety, performance and comfort of the car. Traditional automotive wiring harness cables are mainly made of copper conductors and ordinary insulating materials such as PVC. These materials can meet basic electrical performance and mechanical strength requirements under normal use conditions.

[0003] Automotive wiring harnesses and cables may face multiple potential threats such as high temperature, short circuit, and external fire sources in complex operating environments. Once a cable catches fire, it will not only quickly spread to the entire vehicle body, causing electrical system failure and loss of vehicle function, but may also cause more serious fires, posing a huge threat to the safety of passengers' lives and property.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, a wiring harness cable for automobile is provided, which utilizes the structure of outer sheath, reinforcement layer, shielding layer, insulating layer, conductor, fire-resistant layer and flame-retardant filler. The outer sheath is provided as the outermost layer of the cable, which plays a protective and wear-resistant role, and effectively prevents the damage of the internal structure by external factors such as mechanical damage and chemical corrosion. Next is the reinforcement layer, which is located inside the outer sheath and is used to enhance the mechanical strength of the cable so that it can withstand external forces such as stretching and bending. The shielding layer is used to reduce electromagnetic interference and protect the integrity and accuracy of signal transmission. The insulating layer is wrapped around the conductor to ensure that the current flows in the conductor without leaking to the outside, and effectively prevents short circuit and electric shock. Danger, the conductor is the core part of the cable, responsible for transmitting current or signals. The fire-resistant layer is located inside the outer sheath to improve the fire resistance of the cable. Even under the action of an external fire source, it can maintain its integrity for a certain period of time. Finally, the flame-retardant filler is located in the gap around the conductor to slow down the spread of fire and further improve the flame retardant properties of the cable. It solves the problem that the automotive wiring harness cable may face multiple potential threats such as high temperature, short circuit, and external fire source in a complex use environment. Once the cable catches fire, it will not only quickly spread to the entire vehicle body, causing failure of the electrical system and loss of vehicle function, but may also cause more serious fires, posing a huge threat to the safety of passengers' lives and property.
