As people of comfort, economy, security requirements continue to increase, the type of car electronic products is also increasing, the failure rate increasing complexity of automotive wiring harness harness also increased. This requires improving the reliability and durability of the harness and other properties, many people for the production of automotive wiring harness technology and more interested in where Ho Chi electronics to be a simple narrative on knowledge of automotive wiring harness technology and production in this area, you just need to take a few minutes to read, you can almost understand. 
After a two-dimensional product drawings automotive wiring harness out to choreography harness production process, the production process is to serve the two are inseparable, so I will both produce and process to combine the analysis of automotive wiring harness together. 
Harness the production of the first station is open line process. The accuracy of the opening line process is directly related to the entire production schedule, if an error occurs in particular the size of the opening line is shorter, it will lead to rework all the stations, and time-consuming impact productivity. Therefore, in the preparation process is the opening line must reasonably determine the size of the wire open line drawings upon request, stripping head size. 
The second station is the opening line after crimping process, according to the terminal crimping parameters required to determine the type of drawing, making crimping operation manual, there are special requirements for the need to indicate in the process documents and training operatives. For example: some wires through the jacket before the need to crimp, it needs to be pre-installed wire and then returns from the pre-position and then crimp; There punctured crimping use special crimping tools, which kind of crimping method has a good electrical contact performance. 
Next is pre-process, the first process to prepare pre-installed operating instructions, in order to improve assembly efficiency, complex wiring harness must be pre-set stations, pre-process is reasonable or not directly affect the efficiency of the final assembly also reflects a technical level technology staff level. Conductor path if too few or partially assembled pre-assembled unreasonable will increase the workload of the general assembly staff, slow down the process line speed so often to stay on-site staff to constantly sum. 
The final step is, assembly processes. Compiled according to the product development department can design platen assembly, design tooling equipment, materials and all assembly Size box jacket and accessories number affixed to the material in order to improve the efficiency of the assembly box. Preparation and content of each station assembly requirements, balancing the entire assembly station a little work to prevent excessive pull down the whole line speed situation. To achieve a balance station, craft personnel must operate the familiar scene in the heart of each and calculation of working hours, at any time to adjust the assembly process. 
In addition, the harness process also includes the preparation of material consumption of fixed schedules, working hours estimates, worker training, etc., due to technical content value is not high, they also would not elaborate. All in all, automotive wiring harness in the car electronics technology content and quality, has become an important indicator of the performance evaluation of the car. Harness choice for car manufacturers should give particular attention, it is necessary to understand the next car harness technology and production.
