Automotive wiring harness assembly process and attention to detail

The assembly of automotive wiring harnesses is to wrap a variety of different types of wires into bundles, which not only effectively strengthens the protection of the insulation layer, but also further saves more space. The assembly process of automotive wiring harnesses: Before assembling automotive wiring harnesses, you need to be familiar with the principle of the circuit diagram, as well as the wiring and processing of each part. There are two parts in the production and processing of automobile wiring harness. The first part is the crimping terminal, which has two forms: fully automatic crimping and semi-automatic crimping. The second part is the assembly process, which can be divided into pre-assembly process and final assembly process.

Points to note when assembling automotive wiring harnesses: 1. Pay attention to the selection of connectors and sheaths of automotive wiring harnesses, because generally chassis wiring harnesses are made of corrugated sheaths with good flame retardancy and mechanical properties, while cab wiring harnesses are made of cold-resistant and heat-resistant insulation. Wrapped with plastic tape, it should be assembled and produced according to the working environment of automotive wiring harnesses. 2. Reduce the segmented production of automotive wiring harnesses. In order to facilitate subsequent assembly and maintenance, automotive wiring harness manufacturers generally carry out segmented manufacturing and connect multiple segments of wiring harnesses together through connectors. In automotive applications, the fewer segments of the wiring harness, the better, which can avoid too many connectors resulting in voltage drop, resulting in poor contact. At the same time, segmented production can timely find defective products such as poor contact, poor insulation and assembly errors. 3. Avoid the problem of poor wiring harness contact in automobile wiring harness assembly. This factor is mostly caused by the connector. When a fault occurs, the electrical equipment cannot work normally. You can eliminate the connector fault by connecting the power supply of the electrical equipment and using detection and testing tools. 4. When assembling the automobile wiring harness, do not pull the wiring harness too tightly (especially if the wiring harness is arranged horizontally) to avoid the loosening of the fixed points of the wiring harness when the vehicle bumps, which will lead to a sudden increase in the distance between the two fixed points, resulting in poor internal contact contact, wire parameters change or even break the wire. 5. The automobile wiring harness cannot be arranged with connectors of the same model and color to avoid errors during the assembly process leading to defective products. 6. After the automobile wiring harness is assembled, it is necessary to leave enough gap to ensure that it is not overwhelmed or tripped by other components, and to avoid the ground fault caused by the insulation layer of the wiring harness being pinched, worn or cracked.
