For automobile manufacturers , the automotive wiring harness in the production process of the material requirements are more stringent standards, such as wire and raw materials have good electrical properties, the material sporadic resistance, temperature resistance , etc., because of automotive wiring harness in cars process plays an important role, so for safety considerations but also regulate the production and strict requirements.
     Automotive wiring harness according to the function of different types have different categories , there are carriage drive actuators ( actuator ) power line power and transmission sensor input command signal line two , automotive wiring harness is the main network automotive circuits , electrical and electronic components connected to the car make it function , no car circuit wiring harness does not exist .
With the improvement of science and technology development and technology level , increasing the car s functions , more and more electrical parts , wires will be more and more significant increase in the number of cars on the circuit with electricity , wiring harness , becomes The thicker the more severe . This is a big problem to be solved , how to make a lot of automotive wiring harness in a limited space, how much more effective and reasonable layout, making the car harness play a greater function , has become a problem faced by the automotive industry .
