Working Process Of Automobile Wiring Harness In Automobile

The automobile wiring harness is the main body of the network of the automobile circuit. Without the wiring harness, there is no car circuit. The wire harness refers to the contact parts (connector) made of copper material that are crimped with the wire and cable, and then the outside is molded with an insulator or an additional metal shell, and the assembly of the connection circuit is bundled with the wire harness. Ming Yi Da Electronics is a professional manufacturer of complete vehicle wiring harnesses. Its primary operations are: car seat wiring harnesses, car headlight wiring harnesses, vehicle monitoring wiring harnesses, etc., authenticity guarantee, can be customized according to customer requirements, always find the right product for you of.

Automotive wiring harness engineers are responsible for the interior and body wiring, such as wiring planning from the body ECU to the front and rear lights, wiring planning from the sensor in the engine and chassis to the respective ECU, and wiring planning from the control panel to the ECU. The repair profession does not have this position, and there are large car assembly workshops. It is responsible for the planning and equipment of the bus bundle.

The current car wiring harness specifications are primarily QC/T29106 "Car low-voltage wiring harness skill conditions" and the corporate standards of various enterprises. The experimental items may include: testing the quality of the crimping of the terminal and the wire or wire contact, the waterproof function of the contact, and the resistance of the wire harness High and low temperature and damp heat function, salt spray resistance function and vibration resistance function.

Car wires, also known as low-voltage wires, are different from ordinary household wires. The general household wire is a copper single-core wire with certain hardness. The car wires are copper multi-core flexible wires, some of which are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulated tubes (polyvinyl chloride), which is soft and not easy to break.

With the addition of car functions and the widespread use of electronic control skills, there are more and more electrical parts, more and more wires, and the wire harness becomes thicker and heavier. Therefore, the advanced car has introduced CAN bus equipment and selected multiplex transmission system. Compared with traditional wiring harnesses, multi-channel transmission equipment greatly reduces the number of wires and connectors, making wiring easier. With the increasing demands on the safety, comfort and economy of cars, the electrical equipment and functions of cars There are also more and more, so the wiring harness connecting various electrical equipment is becoming more and more messy, becoming a frequent link to the faults of cars in this world, and therefore it is receiving more and more attention in the planning and production of cars.
