Knowledge of Auto Wiring Harness

Overview of Automotive Wiring Harness

Automotive wiring harness is the main circuit network of cars, the system is formed by the copper contacts terminal (connector) remodeling, the outside is pressure crimping and wire and cable insulator or plus metal casing to form a connected circuit harness strapping components. The harness industry is including chain, wire and cable, connectors, processing equipment, wiring harness manufacturing and downstream application industries, wire harness is widely used. It can be used in automobiles, household appliances, computers and communications equipment and electronic instrumentation.

Feature of Automotive Wire Harness
Automotive wiring harness is the main circuit network of cars. Without wire harness, there would be no existence of automotive circuits. At present, no matter the ordinary senior luxury car or the economy car, the harness woven form is basically the same. It is composed by wires, associated plug-ins and parcel tape. Automotive wire, also known as the low-voltage wires, it is not the same as ordinary household wiring. Ordinary household wiring is copper single-core wire, it has certain hardness. The automotive wire harness is copper multi-core cord, some cord is as thin as a hair, there are several or even dozens of soft copper wires wrapped in plastic insulated pipe (PVC), it is soft and not easily broken.

Automotive Wire Harness Materials
Automotive wire harness is also very strict requirements of the material. Including its electrical properties, material sporadic and temperature resistance, these are all higher than general harness requirements, especially those related to the safety aspects, such as the direction control system, the important components of the brake harness has more stringent requirements.

Functions of Auto Wiring Harness
In modern cars, automotive wiring harness in the markets is of various varieties. wiring harness manufacturer has to strengthen their innovative and research ability in order to compete in the competitive market. The electronic control system is more closely related to the wiring harness. The automotive wiring harness is the main body of the car circuit network, connected to the car's electrical and electronic components and function, without harness there will be no existence automotive circuits. At present, whether it is ordinary senior luxury car or economy car, harness woven form is basically the same, are composed by the wires, associated plug-ins and parcel tape, it has to ensure that transmit electrical signals, but also to ensure that the connection circuit the reliability of a predetermined current value to the supply of electrical and electronic components, to prevent the electromagnetic interference to the surrounding circuitry, and electrical short-circuit to be excluded. The automotive wiring harness up points, from the function, the carriage drive an actuator (actuating) electricity power line and passing two kinds of the sensor inputs to the instruction signal line. The power line is carrying a large current coarse wire, while the signal line is not carried in the thin wires of the electric power.
