With the continuous improvement of people's comfort, economy and safety requirements, the types of electronic products in automobiles are also increasing. The failure rate of more and more complex automotive wiring harnesses also increases accordingly. This requires improved wiring harness reliability and durability performance, many people are more interested in the technology and production of automotive wiring harness, where the wisdom of automotive wiring harness technology and production of this knowledge to make a brief statement, you only need Spent a few minutes to read, you can get a general understanding. After the two-dimensional drawings of the automobile wiring harness come out, it is necessary to arrange the production technology of the wiring harness and the craft to serve the production. The first station of the wiring harness production is the open-line process. The accuracy of the open-line process is directly related to the entire production schedule. In the event of an error, especially if the open-wire size is too short, the rework of all the stations will be caused, which may affect the production efficiency time-consumingly and laboriously. Therefore, in the preparation of open-line technology must be based on the drawings required to determine the reasonable open wire size, stripping size. Electronic wiring harness

The second station after opening the line is the crimping process. The crimping parameters are determined according to the terminal type required by the drawing, and the crimping operation instruction is made. For the special requirements, the operator should be noted and trained on the process document. For example: Some wires need to be passed through the sheath before crimping, it needs to be pre-installed wire and then return from the pre-installed station and then crimp; puncture pressure crimp used special crimping tools, which Crimping methods have good electrical contact properties.

Then is the pre-installed process, the first preparation of pre-installed process instructions, in order to improve the assembly efficiency, complex wiring harness should be installed pre-installed station, pre-installed process is reasonable or not directly affect the efficiency of the total assembly also reflects a Technology level of technical personnel. If the pre-installed part of the assembly is too small, or the assembly of the wire path is unreasonable will increase the workload of the total assembly staff to slow down the speed of the line so the craft staff should always stay at the scene continue to summarize.

The final step is the assembly process. According to the product development department to design the assembly platen, design tooling equipment, material box size and size of all the mounting sheath and accessories affixed to the material box to improve the assembly efficiency. Preparation of the various station assembly content and requirements, balance the entire assembly station to prevent a bit workload is too large, pulling down the entire assembly line speed. To achieve the station balance, the process staff must be familiar with each operation and fieldwork man hours, adjust the assembly process at any time.

In addition, the wire harness process also includes the preparation of material consumption quotas, working hours, workers training, due to the technical content is not high, these are not elaborate. All in all, the automotive wiring harness content and quality of electronic technology has gradually become an important indicator to evaluate the performance of the car. Car manufacturers should pay special attention to the choice of wiring harness, it is also necessary to understand the technology and production of wiring harness.
