[0027] The drain wire 5 is arranged in the wrapping layer 3 and is used for grounding connection.

[0028] The power supply wire 6 is arranged in the wrapping layer 3 and is used for connecting a power supply. The product has higher transmission speed, better stability and compatibility, can be applied to various electrical physical scenes, and brings greater market to customers and manufacturers.

[0029] The product has small line diameter, small volume, light weight, good bending resistance and transmission performance, and the attenuation satisfies Max 6.7db / 3M@16.0GHz (in 3 meters, at a frequency of 16.0 GHz, the maximum attenuation is not more than 6.7db), and meets the UL VW-1 flame retardant test.

[0030] The conductor group 4 comprises an insulation layer 44, and the insulation layer 44 is arranged outside the cladding layer 42 and abuts against the outer surface of the cladding layer 42. Specifically, the insulation layer 44 is provided with at least two conductors 41, and each conductor 41 is covered by the cladding layer 42, and the outer surfaces of the cladding layers 42 of different conductors abut against each other. More specifically, the cladding layer 42 and the insulation layer 44 are integrally formed by FEP. The cladding layer is integrally formed by (FEP) perfluoroethylene propylene copolymer, and the cladding layer also has insulation performance, and the air holes (transmission holes) are added in the cladding layer, so that the air layer is formed in the insulation, the dielectric constant of the insulation is effectively reduced, the attenuation degree of data transmission is reduced, and the data quality is ensured. The insulation layer (middle layer) is also integrally formed by (FEP) perfluoroethylene propylene copolymer, and has good chemical resistance, electrical insulation and temperature resistance.

[0031] The wrapping layer 3 is provided with at least two conductor groups 4, and the conductor groups 4 are filled with the filler 7. Such a structure makes the product more uniform and facilitates signal transmission.

[0032] The drain wire 5 has two roots, the conductor group 4 has two groups, the power supply wire 6 separates the two groups of conductor groups 4, and the two drain wires 5 are arranged on the outer side of the power supply wire 6. Such a structure reasonably utilizes the space in the sheath (wrapping layer), has less signal interference, can set different interfaces, is compatible with multiple devices, and meets the needs of different scenes.

[0033] The conductor 41 is integrally formed by a single 0.285mm silver-plated copper. This makes the silver-plated conductor strong in oxidation resistance, small in contact resistance and good in weldability, and suitable for high-frequency application.

[0034] The tape wrapping layer 3 is formed by combining the metal aluminum foil with the polyester tape after backing with glue. Specifically, the shielding layer 2 is formed by weaving a metal material, and the sheath 1 is integrally formed by SRPVC (semi-rigid polyvinyl chloride). The tape wrapping layer generally uses an aluminum foil Mylar, which is formed by combining a metal aluminum foil with a polyester tape (generally PET, PP, etc.) after backing with glue. The polyester tape of the utility model is made of PP (polypropylene). When the internal core wire is woven, a layer of PP aluminum foil Mylar is wrapped, which can fix the internal core wire and effectively avoid the external emission of internal signals and the interference of external noise signals through the aluminum foil shielding layer, so as to ensure stable data transmission. A layer of metal shielding net is woven outside the aluminum foil tape, which provides the strength of the wire, anti-interference performance and flame retardation effect.

[0035] The transmission hole 43 is circumferentially and uniformly arranged on the cladding layer 42 and arranged around the conductor 41 in the radial section, and is circular or sector-shaped. The hollow transmission hole is arranged to replace the solid insulation layer in the prior art, which reduces the outer diameter of the wire and reduces the signal attenuation and improves the transmission rate by using the optimal air conduction. Specifically, the utility model sets 10 transmission holes. The circular or sector-shaped transmission hole can reasonably utilize the space on the cladding layer and set as many hollow transmission holes as possible. The circular and sector-shaped arrangement has good strength support, can reduce the outer diameter of the cladding layer, reduce the product volume, and still reliably support and protect the conductor to avoid deformation.
