Abstract
The invention relates to a radio frequency coaxial cable, which comprises a polyether-ether-ketone filling body; the silver-plated copper pipe inner conductor is arranged outside the polyether-ether-ketone filling body; the insulator is arranged outside the silver-plated copper pipe inner conductor; the metal outer conductor is arranged outside the insulator; the shielding layer is arranged outside the metal outer conductor; and the outer wall of the polyether-ether-ketone filling body is in close contact with the inner wall of the silver-plated copper pipe inner conductor. The consumption of the inner conductor is reduced, so that the material of the silver-plated copper pipe inner conductor is saved, and the weight of the radio-frequency coaxial cable is reduced, therefore, the radio-frequency coaxial cable is suitable for high-power radio-frequency coaxial cables, and is also suitable for various application occasions with weight reduction requirements on the radio-frequency coaxial cable, such as the aerospace field; the polyether-ether-ketone filling body provides support for the silver-plated copper pipe inner conductor, so that the bending resistance of the silver-plated copper pipe inner conductor is greatly improved, the problem of poor bending caused by the fact that the silver-plated copper pipe inner conductor is used instead of the polyether-ether-ketone filling body is avoided, and the weight is reduced while better bendability is achieved.
