car wire harness manufacturers to improve the technology of car wire harness
car wire harness manufacturers to improve the technology of car wire harness, car wire harness is the main body of the car circuit, connecting the electrical and electronic components of the car and make it play a function, there is no wiring harness does not exist car circuit. From the function point, there are two types of power lines that carry the drive actuator (actuator) power and the sensor input signal. The power line is a thick wire that carries a large current, and the signal line is a fine wire (optical fiber communication) that does not carry electricity. For example, the signal circuit has a conductor cross-section of 0.3 and 0.5 mm2.
In the motor, the implementation of the conductor with a cross-sectional area of 0.85,1.25 mm2, and the power supply circuit with a cross-sectional area of 2,3,5 mm2; car wire harness and special circuits (starter, alternator, engine ground, etc.) 10,15,20 mm2 different specifications. The larger the cross-sectional area of the wire, the greater the current capacity. The choice of wire, in addition to considering the electrical performance, but also by the physical performance of the vehicle when the constraints, so its wide range of options. For example, a frequent open / close door on a taxi and a wire across the body should be made of a wire with good flexing performance. car wire harness In the high temperature parts of the use of wire, generally use the insulation and heat resistance of vinyl chloride, polyethylene coated wire. In recent years, weak signal circuit using electromagnetic shielding lines are also increasing.
With the increase in the function of the car, the universal application of electronic control technology, more and more electrical parts, the wire will be more and more cars on the number of circuits and electricity significantly increased, the wiring harness becomes thicker and heavier The This is a big problem to be solved, how to make a large number of wiring harness in a limited car space how to more effectively rational layout, car wire harness the car harness to play a greater function, has become a car manufacturing industry problems.
