Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
53 words
A module for a modular secondary connector comprising an annular metal body having flat parallel end faces and a radial extension forming a cable-receiving terminal, and an elastomeric insulating coating over said body and at least the first portion of said extension and extending fractionally past the plane of each of said faces.
Claim 2
Dependent Claim
53 words
A module for a modular secondary connector comprising an annular metal body having flat parallel end faces and a radial extension forming a cable-receiving terminal, and an elastomeric insulating coating over said body and at least the first portion of said extension and extending fractionally past the plane of each of said faces.
Claim 3
Dependent Claim
43 words
The module of claim 1 wherein said body is provided with an annular lightly tapered channel at each of said faces, and including a doubly lightly tapered seize ring fitting within one of said channels and the opposite channel of an adjacent module.
Claim 4
Dependent Claim
27 words
A modular assembly of a plurality of modules as defined in claim 1 including terminally insulated bolt and nut means holding said modules in tight face-to-face contact.
Claim 5
Dependent Claim
27 words
A modular assembly of a plurality of modules as defined in claim 2 including terminally insulated bolt and nut means holding said modules in tight face-to-face contact.
Claim 6
Dependent Claim
23 words
The assembly of claim 3 wherein said nut is circumferentially exteriorly grooved and is covered with a correspondingly internally ridged insulative elastomeric cap.
Claim 7
Dependent Claim
65 words
Method of connecting cables suitable for use in underground residential distribution systems comprising cOnnecting each said cable to a connector module as defined in claim 1, insulatively protecting the connection, and assembling said modules together under compression sufficient to provide tight conductive contact between adjacent faces of said modules and to compress the adjacent fractional extensions of said insulating coatings to form a water-impenetrable seal.
Claim 8
Dependent Claim
89 words
Method of connecting cables suitable for use in underground residential distribution systems comprising connecting each said cable to a connector module as defined in claim 2, insulatively protecting the connection, assembling said modules with an intervening seize ring between each two adjacent modules along a central support, and compressing said modules and ring together under pressure sufficient to cause seizure of said rings in said modules and permanent conductive contact between said modules and to compress the adjacent fractional extensions of said insulating coatings to form a water-impenetrable seal.
