What is the automotive wiring harness production process? What is automotive wiring harness?

An automotive wiring harness is an electrical wiring harness system installed in an automobile, which consists of multiple wires and connectors used to connect various electrical devices, sensors, and actuators of an automobile together. Automotive wiring harness plays the role of electrical conduction, signal transmission and power supply, and is one of the core components of the automotive electrical system. The production process of automotive wiring harnesses usually includes the following major steps: design and planning: first, according to the needs and design requirements of the vehicle's electrical system, to develop the design and planning program for the wiring harness. This includes determining the layout, length, wire diameter, insulation material, connector type and location of the harness. Material preparation: According to the design program, prepare the required materials, including wires, insulation sleeves, connectors, protection sleeves, etc. These materials need to comply with the relevant standards and specifications of the automotive industry. Wire Cutting and Stripping: Cut the wires according to the length required by the design, and strip off a certain length of insulation at the end for connection. Wire Harness Assembly: The stripped wires are assembled according to the layout requirements in the design program. This includes arranging, bundling and tying the wires to form the structure of the entire harness. Wire Harness Insulation: Insulate and protect the wire harness using materials such as insulating sleeves, protective sleeves, etc. to prevent short circuits between wires, electromagnetic interference and mechanical damage. Connector Installation: Install the connector to the end of the wire harness, the selection and installation of the connector need to comply with the design requirements and standards to ensure the reliability and stability of the connection. Testing and Quality Control: Test the assembled wire harness, including conductivity test, insulation test, electrical performance test, etc., to ensure that the wire harness meets the specifications. Quality control is also performed to ensure that each process meets quality standards. Packaging and Delivery: The tested and quality-controlled harnesses are packaged for storage and transportation. Finally, the harness is delivered to the automobile manufacturer for installation and use. In short, the production process of automotive wiring harnesses includes design planning, material preparation, wire cutting and stripping, wiring harness assembly, wiring harness insulation, connector installation, testing and quality control, and packaging and delivery. Each link needs to be operated in strict accordance with relevant standards and specifications to ensure the quality and reliability of the harness. It should be noted that different automobile manufacturers and different car models may have some subtle differences and special requirements, so the actual production process may vary. The above description only provides a general overview of the general automotive wiring harness production process.
