Power tool harness manufacturers believe that with the gradual improvement of production technology, electric automotive wiring harness, as the main connection and transmission system of automobile signal transmission, automobile power supply and automobile function realization, will be paid more and more attention. However, with the price reduction of domestic Tesla and the addition of many brands of electric vehicles, the competition in the follow-up industry will become more intense. Only by virtue of high-quality, high-value products and leading technology can enterprises occupy a place in the fierce new energy vehicle market. While carrying out technological innovation, major car companies will also pay attention to the cost optimization of spare parts, improve product strength and enhance their competitiveness.

Power tool harness manufacturers believe that high-voltage harness is a high-value component in pure electric vehicles, and it is also the main component for cost optimization. The cost of high-voltage wire harness consists of material cost, processing cost, packaging and transportation cost and management cost. The material cost of high-voltage wire harness is mainly determined by the technical scheme of wire harness, and the processing cost includes artificial water and electricity cost, equipment depreciation cost and low-value consumables. The following is the cost composition chart of high-voltage wire harness and the cost composition chart of high-voltage wire harness materials. The material cost of high-voltage wire harness accounts for about 73.8% of the total cost of wire harness. The processing cost accounts for 14.7%, so it is necessary to optimize the design and production process to continuously reduce the cost of high-voltage wire harness.

The manufacturer of power tool harness thinks that the cutting size of electric wire should be accurate, conform to the tolerance requirements, and should not be too long or too short. The cut end face should be flat, the number of scratched copper wires should meet the standard, and there should be no scattering and bulging after peeling. For multi-core cables, each cable needs to be peeled separately. Before peeling, the filler should be removed, which should not exceed the standard of scratching copper wire. When multi-core cables are assembled in connectors, cable crossing should be avoided. If a single cable is stressed, it is easy to cause the terminal to come out.

Power tool harness manufacturers think that according to the structure of connectors in each application, the content of tail accessories should be defined, and open and closed bellows should be selected according to the actual situation. If you choose the length of the closed bellows and bellows, it determines the convenience of the tail accessories. This process is very important. If the tail fittings are missing during pre-assembly, or found after crimping, they can't be reworked, and only the semi-finished products can be processed at a fee. When the low-voltage wire and the high-voltage wire are wound and assembled together, a certain length should be left at the tail of the low-voltage wire harness to prevent the tension from coming out; Some terminals installed in connectors need to be designed with special tooling to prevent the wire sheath from bulging; Waterproof bolt components are not allowed to be pierced by sharp objects, and special tooling needs to be designed.

The above are some knowledge points about the wire harness of power tools, and we hope they can help you.
