Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
An environmentally-sealed cable splice which comprises: (a) a butt cable splice between at least two substantially side-by-side cables; and (b) a re-enterable enclosure heat-shrunk around the cable splice, the enclosure comprising (i) a first substantially tubular part through which said cables extend and an outlet, said outlet being heat-shrunk around the cables, and (ii) a second part which is hollow and which together with the first part forms a closed space within which lies the cable splice, the second part being attached to the first part but separable therefrom by cutting the closure; the first part or second part having a portion that has an inside diameter that is substantially equal to the outside diameter of a portion of respectively the second part or first part such that after said cutting the portion of one of the first and second parts can be slid within the portion of the other of the first and second parts to reconstitute the closure.
Claim 2
Dependent Claim
160 words
An environmentally-sealed cable splice which comprises: (a) a butt cable splice between at least two substantially side-by-side cables; and (b) a re-enterable enclosure heat-shrunk around the cable splice, the enclosure comprising (i) a first substantially tubular part through which said cables extend and an outlet, said outlet being heat-shrunk around the cables, and (ii) a second part which is hollow and which together with the first part forms a closed space within which lies the cable splice, the second part being attached to the first part but separable therefrom by cutting the closure; the first part or second part having a portion that has an inside diameter that is substantially equal to the outside diameter of a portion of respectively the second part or first part such that after said cutting the portion of one of the first and second parts can be slid within the portion of the other of the first and second parts to reconstitute the closure.
Claim 3
Dependent Claim
36 words
A sealed splice according to claim 1, in which the portion of one of the first and second parts is a substantially sealing fit within the portion of the other of the first and second parts.
Claim 4
Dependent Claim
22 words
A sealed splice according to claim 1, in which the first and second parts can be separated by a single cut line.
Claim 5
Dependent Claim
19 words
A sealed splice according to claim 1, in which the enclosure has guide means to facilitate making the cut.
Claim 6
Dependent Claim
21 words
A sealed splice according to claim 1, in which the enclosure has a line of weakness to facilitate making the cut.
Claim 7
Dependent Claim
43 words
A sealed splice according to claim 1, in which each of the first and second parts has a flange, which flanges abut one another when one of the first and second parts is slid within the other of the first and second parts.
Claim 8
Dependent Claim
18 words
A sealed splice according to claim 1, in which the second part has a substantially dome-shaped closed end.
Claim 9
Dependent Claim
15 words
A sealed splice according to claim 1, in which the enclosure is formed by blow-moulding.
Claim 10
Dependent Claim
20 words
A sealed splice according to claim 8 in which the first and second parts are formed integrally with one another.
Claim 11
Dependent Claim
20 words
A sealed splice according to claim 1 in which the first and second parts are formed integrally with one another.
Claim 12
Dependent Claim
37 words
A sealed splice according to claim 1, in which a branch-off seal between the cables and the outlet is formed with a branch-off clip between the cables and having legs of the clip extending outside the outlet.
