How are engine wiring harnesses produced? What are the main manufacturers of engine wiring harnesses?

An engine wiring harness is an electrical harness that connects the various components of an engine to transmit power and signals. It plays a key role in engine drive systems in automobiles, airplanes, ships, etc. The process of producing an engine wiring harness usually involves stages of design, manufacturing and testing. The following is the general engine wiring harness production process: 1. Design phase: System design: According to the function and requirements of the engine, determine the overall layout and connection of the wiring harness. Electrical design: According to the system requirements, design the electrical characteristics of the wiring harness, including voltage, current, resistance and other parameters. Material Selection: Select wires and insulation materials that are suitable for engine environment with high temperature, vibration and corrosion resistance.2. Manufacturing Stage: Wire Processing: According to the design requirements, the wires will be cut, stripped and crimped terminals and other processing operations. Insulation Sleeve Installation: Insulation sleeves are put on the wires to protect the wires and ensure the safety of the wire harness. Harness assembly: The processed wires are assembled according to the design requirements, including tying, braiding and fixing steps to form a finished harness. Connector Installation: According to the connection requirements of the engine, connectors and plugs are installed to realize the connection between the wiring harness and engine components. Shielding treatment: Shielding treatment is carried out on the wiring harnesses that need to be shielded to minimize electromagnetic interference.3. Testing phase: Electrical testing: Electrical performance testing is carried out on the wiring harnesses, including conductivity testing, insulation testing, and resistance testing, etc., to ensure that the wiring harnesses are of normal quality and function. Reliability testing: vibration test, high temperature test, humidity test and other reliability tests to verify the stability and durability of the harness in a variety of environmental conditions.
