Abstract

The present invention discloses a coaxial cable. The coaxial cable comprises a central conductor, a dielectric layer wrapping the outer side of the central conductor, a shielding layer wrapping the outer side of the dielectric layer and a sheath wrapping the outer side of the shielding layer, and the shielding layer structurally comprises a first graphene coated copper foil layer, a copper wire woven mesh layer and a second graphene coated copper foil layer; the first graphene coated copper foil layer is formed by coating the dielectric layer with graphene coated copper foil, the copper wire woven mesh layer is formed by coating the first graphene coated copper foil layer with a copper wire woven mesh, and the second graphene coated copper foil layer is formed by coating the copper wire woven mesh layer with graphene coated copper foil; and the copper layers on the first graphene coated copper foil layer and the second graphene coated copper foil layer are tightly attached to the copper wire woven mesh layer. The coaxial cable has excellent shielding performance, the shielding attenuation in the range of 30 MHz to 1000 MHz can be improved from more than 95 dB to more than 110 dB, and the shielding attenuation in the range of 1000 MHz to 3000 MHz can be improved from more than 85 dB to more than 100 dB.

Description

technical field [0001] The invention relates to the field of cables, in particular to a coaxial cable and a manufacturing method thereof. Background technique [0002] As the market demands higher and higher shielding performance of coaxial cables, the shielding attenuation in the range of 30MHz to 1000MHz has been increased from more than 95dB to more than 110dB, and the shielding attenuation in the range of 1000MHz to 3000MHz has been increased from more than 85dB to more than 100dB. The structure of the existing coaxial cable includes: a central conductor, a dielectric layer is coated on the outside of the central conductor, and a shielding layer is coated on the outside of the dielectric layer. The shielding layer is used to shield the interference of the electromagnetic field. The outer side is covered with a sheath; the structure of the shielding layer includes: an aluminum foil layer wrapped on the outer side of the dielectric layer and a metal braided mesh layer wrap...
