Coaxial cable with dielectric layer including sealing section and method of manufacturing same

Abstract

The invention discloses a coaxial cable, comprising: a central conductor; a dielectric layer surrounding the central conductor in the circumferential direction; and an outer conductor surrounding the dielectric layer in the circumferential direction. The dielectric layer includes an inner sleeve circumferentially covering the central conductor and an outer sleeve circumferentially covering the inner conductor. The outer sleeve contacts the inner sleeve to form a plurality of longitudinally spaced seams to form a plurality of seal segments along the longitudinal axis of the cable.

Description

[0001] related application [0002] This application claims priority to, and the benefit of, U.S. Provisional Patent Application No. 62 / 237954, filed October 6, 2015, the disclosure of which is incorporated herein in its entirety. technical field [0003] The present invention relates generally to cables, and more particularly to coaxial cables. Background technique [0004] A coaxial cable typically includes an inner conductor, an outer conductor, a dielectric layer separating the inner and outer conductors, and a jacket surrounding the outer conductor. The outer conductor can take many forms including flat, braided and corrugated. [0005] The dielectric layer is typically formed from a foamed polymer material. However, in some instances, attempts have been made to increase the amount of air present in the dielectric layer since less material / more air in the dielectric layer can reduce signal loss and / or increase the propagation speed of the signal. However, these metho...
