Abstract
Abstract A plug for sealing an end of a coupling assembly secured to an end of a coaxial cable includes a flange having an end face which has a cross-sectional area substantially less than a cross-sectional area of a threaded portion of the plug, the end face being urged against an end face of the coupling assembly to form a seal therewith.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
An apparatus for sealing a coaxial cable, comprising: a connector disposed on an end of the cable so as to terminate the cable, the connector having an exposed face surrounded by an internal surface, the face and the internal surface defining a cavity having an open side, the face forming part of the cable end, and a plug having threads engageable with the connector so as to close the cavity, an end face of the plug confronting the connector exposed face having formed therein a surface having an outermost cross-sectional area substantially less than the cross-sectional area of a threaded portion of the plug, the plug including a flange which interconnects the plug threaded portion and the plug end face, the flange having a cross-sectional area subatntially less than the plug threaded portion, the plug being threadably secured to the connector such that the plug surface is sealingly deformed against the connector face and maintained thereagainst, the plug electrically isolating the cable end.
Claim 2
Independent Claim
163 words
An apparatus for sealing a coaxial cable, comprising: a connector disposed on an end of the cable so as to terminate the cable, the connector having an exposed face surrounded by an internal surface, the face and the internal surface defining a cavity having an open side, the face forming part of the cable end, and a plug having threads engageable with the connector so as to close the cavity, an end face of the plug confronting the connector exposed face having formed therein a surface having an outermost cross-sectional area substantially less than the cross-sectional area of a threaded portion of the plug, the plug including a flange which interconnects the plug threaded portion and the plug end face, the flange having a cross-sectional area subatntially less than the plug threaded portion, the plug being threadably secured to the connector such that the plug surface is sealingly deformed against the connector face and maintained thereagainst, the plug electrically isolating the cable end.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1, a longitudinal axis of the flange being substantially parallel to a longitudinal axis of the plug, an inner surface of the flange diverging outwards along a direction away from the plug threaded portion.
Claim 4
Dependent Claim
11 words
The apparatus of claim 1, the flange having a conical shape.
Claim 5
Dependent Claim
18 words
The apparatus of claim 3, the plug threads being external threads engageable with internal threads of the connector.
Claim 6
Dependent Claim
71 words
The apparatus of claim 4, further comprising an elongated elastomeric ring having an unstretched substantially uniform cross-section along its entire length, an unstretched inside diameter of the ring being less than an outside diameter of the plug threads and an outer nut surface surrounding the connector internal threads, the ring being disposed on parts of both the outer nut surface and the plug threads so as to form a seal therebetween.
Claim 7
Dependent Claim
15 words
The apparatus of claim 5, further comprising the connector secured to a coaxial cable end.
