Abstract
The present invention provides a coaxial cable having increasing moisture absorbency to remove moisture present in the cable and to prevent corrosion of the conductors in the cable. The coaxial cable of the invention includes an inner conductive tube, a moisture-absorbent material within the inner conductive tube, a dielectric surrounding the inner conductive tube, and a tubular metallic outer sheath surrounding the dielectric. The present invention further includes a method of making a coaxial cable that is capable of absorbing moisture that is present in the cable.
Claims31
A coaxial cable comprising an inner conductive tube;
- a plastic rod adjacent an inner surface of the inner conductive tube, the plastic rod comprising a foamed polymeric layer and a solid polymeric layer surrounding the foamed polymeric layer and adjacent an inner surface of the inner conductive tube;
- and a moisture-absorbent material provided on an interface between said foamed polymeric layer and said solid polymeric layer.
A coaxial cable comprising an inner conductive tube;
- a hollow plastic rod adjacent an inner surface of the inner conductive tube;
- a central structural member adjacent an inner surface of said plastic rod and supporting said plastic rod, wherein said central structural member includes more than one moisture absorbing material, each of said moisture-absorbent materials having a different rate of moisture absorbency;
- a dielectric surrounding the inner conductive tube, and a tubular metallic outer sheath surrounding the dielectric.
A coaxial cable comprising a desiccant-filled reinforcing member;
- a cylindrical plastic rod surrounding said desiccant-filled reinforcing member;
- a smooth-walled inner conductive tube surrounding said cylindrical plastic rod, a foam polymer layer surrounding the inner conductive tube and adhesively bonded thereto, a smooth-walled tubular copper outer sheath closely surrounding the foam polymer dielectric layer, and a protective polymer jacket surrounding said outer sheath and adhesively bonded thereto.
