With the increasing requirements of current applications, electronic wiring harnesses have a significant impact on wiring. The requirements are gradually approaching the limit level of wiring, so the accuracy testing of testing equipment is becoming increasingly important. Inaccurate or impractical testing equipment will pose a serious threat to the normal operation of the entire system in the future.
The process design of wire harness products is the input and output process of the product. The entire design scheme is centered around quality, cost, and operability, ultimately meeting various requirements of product characteristics while controlling manufacturing costs. When the process design is carried out, the first thing to consider is product quality, ensuring that the contact positions do not overlap, are not too large, and are not designed on branches; Secondly, consider the operability of workers' production and minimize the difficulty of work to the greatest extent possible; Finally, follow the principle of nearest grounding and try to save wire as much as possible. Determine the centralized crimping point position of the grounding wire inside the harness, the centralized connection method of the internal connection points, and formulate technical requirements. Due to the different branch positions, sizes, electrical functions, grounding points, and quantities in different car wire harnesses, the internal connection methods of grounding wires are diverse.
With the increasing functionality of automobiles, the widespread application of electronic control technology, and the growing demand for safety, comfort, and economy, there are also more and more electrical configurations and functions on cars; As the number of electrical components increases, so will the number of wires; The wiring harness connecting various electrical components is becoming increasingly complex, and the car wiring harness is also becoming thicker and heavier. Therefore, advanced cars have introduced bus configurations and adopted multi-channel transmission systems.
