Abstract
Abstract A wraparound cable splice case comprises a hollow, relatively rigid, cylindrical shell having at least one longitudinal split along its length and a plastic sheet bonded to its outer surface. A closure member comprises an extension of the plastic sheet extending beyond one of the longitudinal edges along the split. The splice case can be opened along the longitudinal split, wrapped around a cable splice, then closed to encircle the splice. The closure member is coated on its inner surface with a heat activatable adhesive so that when the case is closed around the splice and heat is applied, the adhesive bonds the closure member to the plastic sheet covering the shell. The splice case is particularly suitable for protecting a splice in armored power cable.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
A splice case comprising: (a) a hollow cylindrical shell of a relatively rigid material, said shell having an internal diameter sufficient to encircle a cable splice; and having at least one longitudinal split extending along the length thereof so that the shell can be opened to be placed about a cable splice and then closed to completely encircle the cable splice; (b) a sheet of plastic material bonded to the outer surface of said shell; and (c) a closure member which comprises an extension of said plastic sheet extending from one of the edges of said shell along said longitudinal split, said closure member being coated on the inner surface thereof with a heat activatable adhesive so that when the shell is placed about a cable splice and the closure member is placed in contact with said plastic material covering said shell and heated, the adhesive bonds the closure member to the plastic material, thereby forming a protective splice case.
Claim 2
Dependent Claim
160 words
A splice case comprising: (a) a hollow cylindrical shell of a relatively rigid material, said shell having an internal diameter sufficient to encircle a cable splice; and having at least one longitudinal split extending along the length thereof so that the shell can be opened to be placed about a cable splice and then closed to completely encircle the cable splice; (b) a sheet of plastic material bonded to the outer surface of said shell; and (c) a closure member which comprises an extension of said plastic sheet extending from one of the edges of said shell along said longitudinal split, said closure member being coated on the inner surface thereof with a heat activatable adhesive so that when the shell is placed about a cable splice and the closure member is placed in contact with said plastic material covering said shell and heated, the adhesive bonds the closure member to the plastic material, thereby forming a protective splice case.
Claim 3
Dependent Claim
21 words
A splice case in accordance with claim 1 wherein said shell comprises two half-cylinders having two pairs of interlocking longitudinal edges.
Claim 4
Dependent Claim
14 words
A splice case in accordance with claim 2 wherein said half-cylinders are of metal.
Claim 5
Dependent Claim
15 words
A splice case in accordance with claim 3 wherein said half-cylinders are of galvanized steel.
Claim 6
Dependent Claim
28 words
A splice case in accordance with claim 2 wherein said shell is provided with a plurality of spaced apart prongs extending longitudinally from the ends of said shell.
Claim 7
Dependent Claim
68 words
A splice case in accordance with claim 5 wherein the splice case further comprises two heat shrinkable sleeves coated on the internal surface thereof with adhesive so that when said sleeves are positioned over the prongs and the adjacent sections of said splice case and underlying cable and heat is applied, the sleeves shrink down over the prongs, sealing said sleeves to said splice case, prongs and cable.
Claim 8
Dependent Claim
17 words
A splice case in accordance with claim 1 wherein said sheet of plastic material is heat shrinkable.
Claim 9
Dependent Claim
19 words
A splice case in accordance with claim 1 wherein said sheet of plastic material is composed of crosslinked polyethylene.
Claim 10
Dependent Claim
152 words
A splice case comprising: (a) a hollow cylindrical shell of a relatively rigid material, said shell having an internal diameter sufficient to encircle a cable splice; and having at least one longitudinal split extending along the length thereof so that the shell can be opened to be placed about a cable splice and then closed to completely encircle the cable splice; (b) a sheet of heat sealable plastic material bonded to the outer surface of said shell; and (c) a closure member which comprises an extension of said plastic sheet extending from one of the edges of said shell along said longitudinal split, said closure member being heat sealable so that when the shell is placed about a cable splice and the closure member is placed in contact with said plastic material covering said shell and heated, the closure member is bonded to the plastic material, thereby forming a protective splice case.
Claim 11
Dependent Claim
152 words
A splice case comprising: (a) a hollow cylindrical shell of a relatively rigid material, said shell having an internal diameter sufficient to encircle a cable splice; and having at least one longitudinal split extending along the length thereof so that the shell can be opened to be placed about a cable splice and then closed to completely encircle the cable splice; (b) a sheet of heat sealable plastic material bonded to the outer surface of said shell; and (c) a closure member which comprises an extension of said plastic sheet extending from one of the edges of said shell along said longitudinal split, said closure member being heat sealable so that when the shell is placed about a cable splice and the closure member is placed in contact with said plastic material covering said shell and heated, the closure member is bonded to the plastic material, thereby forming a protective splice case.
