The Importance of Automotive Wiring Harness Assembly

Simply put, automotive wiring harness assembly is the process of wrapping various types of wires into bundles called harnesses. The uniform wrapping protects the insulation and allows for better wiring of parts and saves space. The materials used in automotive wiring harnesses are mainly wires, connectors and sensors. Now we will explain the points to be noted and the importance of automotive wiring harness assembly.

Automotive wiring harness assembly process before the automotive wiring harness assembly, certainly need to familiarize with the circuit diagram principle, each part of the wiring and processing, to facilitate subsequent processing. Automotive wiring harness production and processing can be divided into two parts, part of the crimping terminals, including the fully automatic crimping and semi-automatic crimping in two forms. The second part of the assembly process, assembly process can be divided into pre-assembly process and total assembly process. Specifically, you can refer to this blog: automotive wiring harness production process of automotive wiring harness assembly points to note the selection of connectors and sheaths: general chassis wiring harnesses are flame retardant and mechanical properties of the better corrugated sheaths, and cab harnesses are used in the cold, heat-resistant insulating plastic tape wrapping. According to the working environment of the automobile wiring harness to assembly production. Segmented production: In order to facilitate subsequent assembly and maintenance, automotive wiring harness manufacturers generally segmented manufacturing, through the connector to connect multiple segments of the wiring harness together, in automotive applications, the wiring harness, the fewer the better, you can avoid the connector is too much so as to generate a voltage drop, resulting in poor contact. At the same time, segmented production can be timely detection of poor contact, insulation and assembly errors and other defective products. Wiring harness poor contact judgment: most of the reasons are out in the connector. When the fault occurs, the electrical equipment can not work properly. The electrical equipment can be connected to the power supply, through the detection of test tools to rule out the connector failure. Automotive wiring harness assembly do not pull the wiring harness too tight (especially horizontal arrangement of the harness), to avoid vehicle bumps when the wiring harness fixed point position loose, which leads to a sudden increase in the distance between the two fixed points caused by the wiring harness inside the contact point poor contact, wire parameter changes and even pull off the wire. Do not arrange the same type and color of plugs to avoid misplugging in the assembly process, resulting in defective products. After assembling the wiring harness, it is necessary to leave enough clearance to ensure that it will not be pressed down or tripped by other parts. Avoid wiring harness insulation being pinched off, worn or ruptured and other causes of ground faults. Automotive wiring harness assembly characteristics of automotive wiring harness assembly line of the degree of automation is relatively low, many processes need to be manual to complete, so in the assembly of the automotive wiring harness manufacturing plant needs to have enough labor, inevitably, in the wiring harness assembly will be a certain amount of fluctuation. In the automotive wiring harness manufacturing plant more or less will encounter this situation, in a certain production environment did not complete the assembly task, after more of this situation not only affects the assembly efficiency, but also time-consuming and laborious, resulting in economic losses. So the reasonable allocation of each process is necessary.
