How to distinguish the new energy vehicle wiring harness?

According to the characteristics of the wiring harness, it is the main network component in the automobile circuit. Without the wiring harness, there will be no automobile circuit. Vehicle wires are also called low-voltage wires, which are different from traditional household wires. Conventional household wires are copper single core wires with a certain degree of hardness. Most of the automotive wires are copper multi-core flexible wires, some of which are as thin as hair, and several or even dozens of copper flexible wires are wrapped in plastic insulation tubes, which are soft and not easy to break. Due to the particularity of the automotive field, the manufacturing process of automotive wiring harness is more complex than other wiring harnesses. As far as function is concerned, there are many automotive wiring harnesses, and the electronic control system is closely related to the wiring harness. Nowadays, no matter what type and gear of automobile, the structure of automobile wiring harness is basically the same, which is composed of wires, connectors and wrapping tape. It is not only necessary to ensure the transmission of electrical signals, but also to ensure the reliability of the connection circuit. It is necessary to provide the specified current value to the electronic and electrical components to avoid electromagnetic interference to the surrounding circuit, and also to eliminate the short circuit of electrical equipment. Along with the requirements of driving comfort and driving economy, driving safety is also needed. There are more and more kinds of electronic products on automobiles, and the automotive wiring harness is becoming more and more complex, so the identification of automotive wiring harness is becoming more and more strict. Because of the convenience of casing identification in PVC mode, PVC line number identification pipe is widely used at home and abroad. In order to ensure the clarity and accuracy of installation and facilitate future maintenance and inspection, wiring harness marks have been widely used in various equipment manufacturing fields, covering various automatic control instruments and equipment manufacturing such as electric power and electricity, CNC machine tools, shipbuilding, aerospace, automobile manufacturing and rail transit industries. Many enterprises pay attention to the progress and development of the logo field. In order to be safer and more environmentally friendly, the equipment for directly printing the identification content on the cable without PVC sleeve is developed, and it can automatically cut according to the required length, integrating the three processes of typing, cutting, stripping and threading into one process, which is automatically completed by one equipment. This completely replaces the PVC marking pipe, improves the efficiency of automobile production, avoids human errors, is more environmentally friendly, and reduces material costs. On the whole, the technical content and quality of automotive wiring harness have gradually become an important criterion for evaluating the performance of automobiles. Automobile factories should pay more attention to wiring harness, and also understand the production process and production level of wiring harness and logo.
