The Process And Production Of Car Wire Harness

- Oct 19, 2017-

With the improvement of comfort, economy and safety requirements, the variety of electronic products on the automobile is increasing, and the failure rate of automobile wiring harness is more and more complicated. This requires improved wiring harness reliability and durability and other properties, many people for the car wire harness process and production are more interested in here on the car harness process and production of this knowledge to be a simple description, you only need to spend a few Minutes to read, you can get a general understanding.

In the car wire harness two-dimensional product drawings come out after the layout of the wiring harness production process, the process is to serve the two are inseparable from the production

The first station of the wire harness is the open process. The accuracy of the process is directly related to the entire production schedule, in the event of errors, especially the open line size is short, will lead to all the station rework, time and effort to affect production efficiency. So in the preparation of the opening process is sure to be based on the requirements of the drawings to determine the wire size of the wire, the size of the head.

After the opening of the second station is the crimping process, according to the type of drawings required to determine the crimp parameters, the production of crimp operation instructions, for the special requirements of the need to specify the process documents and training operators. For example: some wires need to wear through the jacket before crimping, it needs to first pre-installed wire and then returned from the pre-installed station and then crimp; there are puncture crimping with a dedicated crimping tool, which Kind of crimping method has good electrical contact performance.

Then is the pre-installed process, and first of all to prepare the pre-installed process operating instructions, in order to improve the efficiency of the assembly, complex wiring harness must be set pre-installed, pre-installed process is reasonable or not directly affect the efficiency of the total assembly also reflects a Technical level of technical staff. If the preloaded part of the assembly of the assembly or less wiring wire path is unreasonable to increase the total assembly staff workload, slow down the speed of the assembly line so the process staff to stay in the field often

The last step is the assembly process. Can be compiled according to the product development department design of the platen, design tooling equipment, material box size and all the assembly sheath and accessories number affixed to the material box to improve the assembly efficiency. The preparation of each station assembly content and requirements, balance the entire assembly station to prevent the occurrence of a little workload is too large, pull down the entire assembly line speed situation. To achieve the balance of the station, the process staff must be familiar with each operation and on-site measurement of working hours, at any time to adjust the assembly process.

In addition, the wiring harness process also includes the preparation of material consumption quota schedule, man-hour calculation, worker training, etc., because the technical content value is not high, these are not elaborate. All in all, the car wire harness in the car electronic technology content and quality, has gradually become an important indicator of vehicle performance evaluation. Car manufacturers for the choice of wiring harness should pay special attention, it is necessary to understand the next car wiring harness technology and production.
