Mobile WebSiteAutomotive wire harness manufacturers are improving the technology of automotive wiring harnesses. The automotive wiring harness is the main body of the automotive circuit. It connects the electrical and electronic components of the car and makes it function. Without the wiring harness, there is no automotive circuit.
Functionally, there are two types of power lines that carry power for driving actuators (actuators) and signal lines that transmit sensor input commands. The power line is a thick wire that carries a large current, and the signal line is a thin wire (optical fiber communication) that does not carry power; for example, a signal circuit has a wire cross-sectional area of 0.3, 0.5 mm2.
The cross-sectional area of the wire for the motor and the actuator is 0.85 and 1.25 mm2, and the cross-sectional area of the power supply circuit is 2, 3, and 5 mm2; and the special circuit (starter, alternator, engine grounding wire, etc.) has 8. 10, 15, 20mm2 different specifications.
The larger the cross-sectional area of the wire, the larger the current capacity. The choice of wires, in addition to considering the electrical performance, is also subject to the physical properties of the vehicle, so the choice is very wide. For example, frequent on/off doors on a taxi and wires across the body should be made up of wires with good flexing properties.
Wires used in places where the temperature is high are generally made of vinyl chloride or polyethylene coated with good insulation and heat resistance. In recent years, electromagnetic shielding lines used in weak signal circuits have also been increasing.
With the increase of the functions of automobiles, the universal application of electronic control technology, more and more electrical components, more and more wires, the number of circuits and the amount of electricity used in automobiles have increased significantly, and the wire harness has become thicker and heavier. . This is a big problem that needs to be solved. How to make a large number of wire harnesses more efficiently and reasonably arranged in a limited car space, and make the automobile wire harness play a greater function has become a problem faced by the automobile manufacturing industry.
