Abstract
Abstract A splice case is disclosed providing sealed protection for splices such as in telephone cable situated in adverse environmental conditions. The case includes a shell defining a cavity for enclosure of a splice. The shell is longitudinally split and includes openings at the ends thereof along the longitudinal split for receiving incoming cable. Thermally responsive sealant extends along the longitudinal split and a heating element is provided for causing the sealant to effectively seal the enclosed splice. A multiple cable adapter of thermally responsive sealant is sized to fit within a cable opening in the splice case and includes a plurality of longitudinally extending channels for accommodation of multiple incoming cables. Sheets of material exhibiting high thermal conductivity extend from the adapter such that the heat of the heating elements may be conveyed to the body of the adapter.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A splice case comprising a shell defining a cavity therein for enclosing a splice, said shell including a longitudinal split and having an opening at one end thereof along said longitudinal split to receive in-coming cable; a thermally responsive sealant positioned along said longitudinal split; a heating element positioned in said shell along said longitudinal split, said thermally responsive sealant being outwardly of said heating element to seal said shell upon heating of said heating element; and an adapter of thermally responsive sealant sized to fit in said opening, said adapter having a plurality of channels extending the length of said adapter for receipt of cables extending into said shell and a sheet exhibiting high thermal conductivity extending from said insert into said split in said shell for heat conduction from said heating element to said adapter.
Claim 2
Dependent Claim
137 words
A splice case comprising a shell defining a cavity therein for enclosing a splice, said shell including a longitudinal split and having an opening at one end thereof along said longitudinal split to receive in-coming cable; a thermally responsive sealant positioned along said longitudinal split; a heating element positioned in said shell along said longitudinal split, said thermally responsive sealant being outwardly of said heating element to seal said shell upon heating of said heating element; and an adapter of thermally responsive sealant sized to fit in said opening, said adapter having a plurality of channels extending the length of said adapter for receipt of cables extending into said shell and a sheet exhibiting high thermal conductivity extending from said insert into said split in said shell for heat conduction from said heating element to said adapter.
Claim 3
Dependent Claim
24 words
The splice case of claim 1 wherein said sheet is a plate extending centrally through the body of said adapter and extending laterally therefrom.
Claim 4
Dependent Claim
28 words
The splice case of claim 1 wherein said sheet is a foil of thermally conductive material positioned within one of said plurality of channels and extending outwardly therefrom.
Claim 5
Dependent Claim
33 words
The splice case of claim 3 wherein said foil includes a layer of heat responsive sealant on a first side thereof, said foil being bonded to said adapter on the other side thereof.
Claim 6
Dependent Claim
16 words
The splice case of claim 1 wherein said adapter is of polyethylene copolymer based adhesive rubber.
Claim 7
Dependent Claim
77 words
