Problems solved by technology

[0002] As the basic connecting part of the new display technology, the new display wire harness plays an important role, and its quality requirements are getting higher and higher, especially for safety and environmental protection issues. The wire harness mainly includes wires, insulating sheaths, wrapping materials and other components. In actual application, due to the particularity of the application environment, the wiring harness components are required to have the characteristics of high and low temperature resistance, fire resistance, weather resistance, corrosion resistance, aging resistance, mold resistance, reliability, flexibility, small size, and light weight. Display wire harness, its fire resistance is particularly important, but the existing wire harness often has low fire resistance, which is easy to cause safety accidents, and is increasingly unable to meet the needs of the market
