Conductor composite material in high-frequency communication cable and high-frequency communication cable made by conductor composite material

Abstract

The invention discloses a conductor composite material in a high-frequency communication cable and the high-frequency communication cable made by the conductor composite material. A core conductor or a shielding layer netted conductor is made of the conductor composite material. The conductor composite material is formed in a way that a metal plating layer is plated outside a circular monofilament or a circular fine tube which is made of a plastic core substrate. The diameter of the circular monofilament or the circular fine tube is larger than 0.1mm and is smaller than 2mm. The thickness of the metal plating layer is larger than 2 micrometers and is smaller than 0.2mm. The metal plating layer at least comprises a surface metal plating layer. A great amount of metal materials can be saved, the cost is greatly saved, the weight is reduced, the transportation expense is saved, the high-frequency communication cable is light and convenient to install, the extension rate of the cable is increased, the tensile strength is improved, the skin effect of high-frequency signals is met and the transmission effect of the signals is not affected.

Problems solved by technology

[0002] In various communication cables, such as audio wires, network cables, coaxial cables, etc., as the core wire conductor for signal transmission or as the conductor of the shielding layer weaving wire, solid metal wires are usually used at present, and their defects are: Metal materials are expensive and heavy, making transportation and installation inconvenient

[0003] Therefore, some cable conductors currently on the market and existing research and development adopt the following structures in order to achieve the purpose of overcoming the above defects. The film uses aluminum as the base material of the conductor, and the outer layer of copper is used for signal transmission. The price is relatively low, but copper is relatively active. When it is closely attached to the aluminum surface, it is easy to migrate, and part of it migrates into the aluminum layer as a transmission The copper layer of the signal effect is easy to disappear, and the effect of high-frequency signal transmission is not very ideal; 2. In some patent documents, some metal-plated materials on the fiber filaments are also disclosed to replace copper wires for making communication The structure of the cable, however, the replacement core conductors of these structures are all coated with metal materials on the outside of a bundle of filaments and long fibers. The disadvantage of the whole bundle of plating is that when transmitting signals, the resistance is very large and the transmission attenuation is large. It is only suitable for the production of protective clothing, and it is difficult to use it as a transmission signal; 3. At present, there are also some core wire conductor structures that use a plastic substrate to coat metal tubes and metal sheets by rolling, but the cost is high. The coefficient of flexion and extension is poor, it is not easy to bend, and the production process is extremely complicated, the tightness of the coating is not easy to control, and the cost is high

[0004] To sum up, there are currently no substitutes for core wire conductors and shielding layer mesh conductors that can better comprehensively achieve low cost and reliable performance with structures and processes
