Abstract
Abstract An annularly corrugated outer conductor is adhesively bonded to the foam dielectric of a coaxial cable at the corrugation roots and adhesively bonded to its tubular plastic sheath at the corrugation crests. Longitudinal passage or migration of fluid is blocked both along the inside and along the outside of the outer conductor without impairment of electrical or mechanical characteristics or complication of attachment of connectors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
28 words
The coaxial cable of claim 1 having an adhesive surrounding all longitudinal portions of the foam but free of contact with the outer conductor in the corrugation crests.
Claim 2
Dependent Claim
25 words
The coaxial cable of claim 1 having the jacket formed of an adhesive plastic free of contact with the outer conductor in the corrugation roots.
Claim 3
Dependent Claim
91 words
In a coaxial cable comprising an inner conductor, a foam dielectric surrounding the inner conductor and adhesively bonded thereto and a corrugated outer conductor surrounding the dielectric and compressing the dielectric at the corrugation roots, the improved construction for sealing the cable against longitudinal high-pressure fluid-flow characterized by the corrugations of the outer conductor being annular and having an adhesive surrounding all longitudinal portions of the foam dielectric within the outer conductor and bonding the roots of the corrugations to the foam, the corrugation crests being free of dielectric and adhesive.
Claim 4
Dependent Claim
59 words
In a coaxial cable having a corrugated outer conductor and a protective jacket surrounding the outer conductor, the improved construction for sealing the cable against longitudinal high-pressure fluid-flow characterized by the corrugations of the outer conductor being annular and the jacket being adhesively bonded to the crests of the corrugations but not bonded to the roots of the corrugations.
Claim 5
Dependent Claim
13 words
The cable of claim 5 having the jacket formed of an adhesive polymer.
