Coaxial cable with dielectric layer having sealed segments and method of making same

Abstract

A coaxial cable includes: a center conductor; a dielectric layer circumferentially surrounding the center conductor; and an outer conductor circumferentially surrounding the dielectric layer. The dielectric layer comprises an inner sleeve that circumferentially overlies the center conductor and an outer sleeve that circumferentially overlies the inner conductor. The outer sleeve contacts the innersleeve to form a plurality of longitudinally-spaced seams to create a plurality of sealed segments along a 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...
