Automotive wiring harness which classification

In Hyundai, electronic control systems and wiring harness are closely related. Someone once called a figurative metaphor: a computer is equivalent to a human brain, a sensor is equivalent to a sensory organ, an actuator is equivalent to an exercise tube, and a harness is a nerve and a blood vessel.

Car wiring harness from the function of points, there are driving power transmission actuator (actuator) power line and the transmission of sensor input command signal line two. Power lines are thick wires that carry large currents, while signal lines are thin wires (optical fiber communications) that do not carry power.

In the motor, the actuator wire cross-sectional area of 0.85,1.25 mm2, and the power supply circuit with wire cross-sectional area of 2,3,5 mm2; and special circuits (starter, alternator, engine ground, etc.) 10,15,20 mm2 different specifications. The choice of wires, in addition to considering the electrical properties, but also by the physical properties of the vehicle when the constraints. For example, frequent on / off doors on a taxi and wires across a car body should be constructed of good flexing wires. In recent years, the weak signal circuit using the electromagnetic shielding wire is also increasing.

With the increase of automobile functions, the universal application of electronic control technology, the number of circuits and the amount of electricity consumption in automobiles have increased significantly, the harder the wires become heavier and heavier, and how to make a large number of harnesses more effective and reasonable in a limited car space Arrangement to make car wiring harness to play a greater function, has become a problem facing the automobile manufacturing industry.

So what are the types of automotive wiring harness?

1, the engine harness, connecting the engine on a variety of sensors and actuators, around the engine around.

2, dashboard wiring harness, and the body or chassis harness connection, walking along the tube and beam connections on the dashboard of various electrical components such as instrument cluster, air conditioning switch, retractable machine, cigarette lighter and so on.

3, the body harness, usually from the cab on the left close to the floor walking, connecting the fuel tank sensor and rear taillight.

4, the door harness, connect the door all the electrical components inside the plate, such as the central lock, glass lifts, speakers and so on.

5, the front fender harness, come from the cab, along the fender and the front bumper backrest connected to the electrical components such as side turn signals and front combination lights, speakers, electronic fans.
