What is an automotive complete vehicle wiring harness? What are the standards and applications of automotive complete vehicle wiring harnesses?

Automotive Wiring Harness (Automotive Wiring Harness) refers to the combination of wires, cables and connectors and other components between the various electrical devices of the car to form a complete wiring harness system to realize the connection and communication of the automotive electrical system. It is an important part of the automotive electrical system, carrying the function of transmitting electrical energy, signals and data. The complete vehicle wiring harness not only connects the various electrical devices of the vehicle, but also plays a role in protecting the wires, preventing interference and scattering signals. The composition of the vehicle wiring harness includes wires, cables, connectors, insulating sleeves, harnesses and protective sleeves. Wire is the basic component of the entire vehicle wiring harness, used to transmit current and signals. Cables are multiple wires tied together to form a wiring harness for transmitting complex signals and data. Connectors are used to connect between the wiring harness and electrical devices, which provide reliable electrical contact and connection. Insulation sleeves are used to protect the wires from mechanical damage and environmental erosion. Ties are used to secure the wire harness and prevent it from coming loose. Protective sleeves are used for the protection of the entire wiring harness to improve its durability and resistance to interference. The standards and applications of the whole vehicle wiring harnesses are mainly in the following aspects: quality standards: the whole vehicle wiring harness must comply with the relevant quality standards of the automotive industry, such as ISO 6722, SAE J1939 and so on. These standards specify the electrical performance of the harness, heat resistance, shock resistance, fire performance, electromagnetic compatibility and other indicators to ensure the reliability and safety of the harness in a variety of environments and working conditions. Safety standards: The wiring harness of the entire vehicle needs to follow a series of safety standards in the design and manufacturing process, such as the requirements to prevent wire short circuit, electrical leakage and fire. These standards include UL, VDE and other safety certification standards to ensure that the wiring harness will not pose a safety risk to the vehicle and occupants during use. Functional requirements: the vehicle wiring harness needs to meet the functional requirements of the vehicle electrical system, such as power supply, lighting, communications, driver assistance, safety systems and so on. The design and layout of the wiring harness should be in line with the needs of the vehicle's electrical system, to ensure that the signals and data between the various electrical devices can be properly transmitted and exchanged. Environmental standards: The manufacturing and use of the wiring harness of the whole vehicle should meet the requirements of environmental protection, such as complying with the RoHS directive to restrict the use of hazardous substances. The material and manufacturing process of the wiring harness should minimize the pollution to the environment and improve the recyclability and reusability of the wiring harness. Standardization and modularity: In order to improve production efficiency and reduce costs, the automotive industry tends to use standardized and modular wiring harness design and manufacturing of the entire vehicle. Standardized harnesses can be applied to multiple models, reducing development and manufacturing costs; modular harnesses can be easily replaced and repaired, improving the reliability and maintainability of the harness. The application of complete vehicle wiring harness is very wide, covering almost all areas of the automobile. The following are some typical applications: engine system: the wiring harness connects the car's engine control unit (ECU), ignition system, fuel injection system, etc., for the transmission of electrical energy and control signals to ensure the normal operation of the engine and performance regulation. Chassis system: The wiring harness of the whole vehicle connects the suspension system, braking system, steering system, etc., which is used for transmitting signals and data to realize chassis control and driver assistance functions. Body system: The wiring harness of the whole vehicle connects the body electronic system, such as door control, central locking, window lifting, seat adjustment, etc., which is used to realize the control and operation of various body parts. Safety system: The wiring harness of the whole vehicle connects the airbag system, anti-lock braking system (ABS), body stability control system (ESC), etc., which is used to transmit and control the signals and data of the safety system, and to improve the safety of the vehicle's passa ride. Multimedia and communication systems: the entire vehicle wiring harness is connected to the car audio system, navigation system, Bluetooth communication system, etc., for the transmission of audio, video, communication and navigation data, to provide in-vehicle entertainment and information services. In short, automotive wiring harness is an indispensable and important part of modern automobiles, which carries the function of transmitting electrical energy and signals to ensure the normal operation of the automotive electrical system and the coordination of work between various devices. By complying with quality standards, safety standards and environmental requirements, as well as being applied to various systems and functional areas, the complete vehicle wiring harness provides reliable electrical connections and functional support for the vehicle, providing a guarantee for vehicle performance, safety and comfort.
