Problems solved by technology

[0002] Generally speaking, wires and cables are composed of conductors, insulation layers and sheath layers, but there are also some cables with shielding layers, which are called shielded cables, such as automotive engine ECU (Electronic Control Unit, electronic control unit, Also known as "driving computer", "vehicle computer", etc., it is the same as an ordinary computer, consisting of a microprocessor (MCU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter ( A / D) and large-scale integrated circuits such as shaping and driving) cables for control systems need to use shielding layers to achieve anti-interference and eliminate surface potential of power cables, while the currently commonly used automotive engine ECU control systems use The shielding layer of the cable is a braided shielding layer of tinned copper wire, but it needs to be braided by special equipment during its preparation, and the weaving is more complicated. At the same time, due to the use of metal such as copper wire, its conductive shielding performance is good, but its quality is heavy. , which is not conducive to the demand for lightweight
