Automotive Wire Harness is the main body of the network of automotive circuits. Without a wiring harness, there is no car circuit. Wiring harness refers to the components that are made of copper and are connected to the wires and cables by crimping, and then externally plastic-insulated or metal shells are used to bundle the components that constitute the connection circuit. In short, It is the wire connecting the car's electrical appliances. The operating conditions and parameters of the car are reflected on the on-board computer through the wiring harness. On the other hand, the electronic technical content of the car wiring harness has become an important goal in evaluating car functions. The car wiring harness is the carrier of the car circuit components. Someone has made an image metaphor before. The car wiring harness is a blood vessel, the car engine is the heart, the heart beats because of the blood vessels, and the engine runs because of the wire harness. The importance of normal stability. So how does the automotive wiring harness work in a car? The following High Quality Electric Wire Harness suppliers will come to tell you.
Automotive Wire Harness
Automotive wiring harness engineers are responsible for interior and body wiring, such as wiring harness planning from body ECUs to front and rear lights, wiring harness planning from sensors in the engine and chassis to respective ECUs, and wiring harness planning from control panels to ECUs. There is no such job in the repairing profession, as there are in large car assembly workshops. It is the planning and equipment of bus bundles.
The current standards for passenger car harnesses are mainly QC / T29106 "Technical Conditions for Passenger Car Low-Voltage Harnesses" and the corporate standards of various enterprises. The experimental items may include: checking the quality of crimping between terminals and wires or wire contacts, the waterproof function of the contacts, 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 are also called low-voltage wires, which are different from ordinary household wires. General household wires are copper single core wires, which have a 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 are 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 harnesses become thicker and heavier. Therefore, advanced buses have introduced CAN bus equipment and selected a multiplex transmission system. Compared with traditional wiring harnesses, multiplexing equipment greatly reduces the number of wires and connectors, making wiring easier. With the increasing demand for safety, comfort and economy of cars, the electrical equipment and functions on cars There are also more and more, so the wiring harnesses connecting various electrical equipment are becoming more and more messy, especially New Energy Car Wire Harness, which has become a frequent problem in cars in this world. Therefore, more and more attention has been paid to car planning and production.
