Abstract
The utility model discloses a coaxial cable, which belongs to the electronic field. The coaxial cable comprises an inner conductor, an insulation layer arranged on outer part of the inner conductor, an outer conductor arranged on the outer part of the insulation layer, and an outer sheath arranged on the outer part of the outer conductor, wherein the insulation layer comprises an inner foaming insulation layer and an outer foaming insulation layer, a soft rubber layer is arranged between the inner foaming insulation layer and the outer foaming insulation layer, and a screening layer is arranged between the insulation layer and the outer conductor. The foaming insulation layers solve the problems that the distance between the inner conductor and the outer conductor is not consistent when the cable is subjected to large extrusion or torsion deformation and thus the inner wireless wave is reflected to a signal source, the toughness and the elasticity of the insulation layers are reinforced by the soft rubber layer, the inner conductor is not easily affected by breaking-off of the outer layer, and the complete performances of the main components are ensured. The screening layer prevents mutual interference between the inner conductor and the outer conductor, and thus the alternative current loop is not affected.
