Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
73 words
A tubular enclosure (10,60) suitable for sealing connections and end terminals in electrical cables comprising: an elastomeric tubular member (12,64); hollow core means (14) for maintaining said elastomeric tubular member (12,64) in a radially expanded state, said core means (14) being removable from said elastomeric tubular member (12,64); and characterised in that said tubular enclosure also comprises a conformable material (16,66) interposed between said elastomeric tubular member (12,64) and said core means (14).
Claim 2
Dependent Claim
49 words
The tubular enclosure (10,60) of Claim 1 wherein said core means (14) comprises a core member constructed of a helically wound flexible strip forming adjacent coils, said adjacent coils being interconnected, and said core member having an outer surface, said outer surface being coated with a release agent (20).
Claim 3
Dependent Claim
33 words
The tubular enclosure (10,60) of any preceding claim wherein said elastomeric tubular member (12,64) is electrically insulative, and further comprising a plurality of skirts (62) formed integrally with said elastomeric tubular member (64).
Claim 4
Dependent Claim
19 words
The tubular enclosure (10,60) of any one of Claims 1-2 wherein said elastomeric tubular member (12,64) is electrically conductive.
Claim 5
Dependent Claim
16 words
The tubular enclosure (10,60) of any preceding claim wherein said conformable material (16,66) is electrically insulative.
Claim 6
Dependent Claim
19 words
The tubular enclosure (10,60) of Claim 5 wherein said conformable material (16,66) has a dielectric constant greater than 15.
Claim 7
Dependent Claim
65 words
The tubular enclosure (10,60) of any preceding claim said enclosure (10,60) being an elastomeric conformable covering suitable for sealing connections in electrical cables, said core means (14) being disposed within said elastomeric tubular member (12,64), said core means (14) being constructed of a helically wound flexible strip (18) forming adjacent coils and being removable from said tubular member (12,64) by withdrawing the flexible strip (18).
Claim 8
Dependent Claim
16 words
The tubular covering (10,60) of any preceding claim wherein said conformable material (16,66) is a mastic.
