Abstract
Abstract A cable sleeve outlet for splice cases comprising a substantially cylindrical member having at least one re-entrant portion and in its longitudinal wall shaped to provide a longitudinal channel, which channel has a longitudinal opening to the exterior of the outlet permitting the re-entrant portion to be wrapped around a cable or similar object aligned with the channel in use, and comprising a fastening means or support means insertable into the open end of the cylindrical member to bridge and thus hold closed the or each said longitudinal opening, the bridging part of the fastening means in use lying across the end cross-sections of the opposing longitudinal wall portions, and the fastening means being so formed that in use it bears on an inner surface of, and thus provides a substantially rigid internal support for, at least part of the longitudinal outside wall of the cylindrical member in addition to the part thereof involved in the said bridging closure. The fastener is preferably in the form of two half-shells with slots which engage the re-entrant portions to hold the openings closed. Sealant material such as hot-melt adhesive is preferably provided on the cable-contacting surfaces of the re-entrant portions and on the fastening means. The cylindrical member may be closed at one end to effect a seal, especially for retaining pressure when used in pressurized splice cases.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
142 words
A cable sleeve outlet comprising: a substantially cylindrical member having at least one re-entrant portion in its longitudinal wall shaped to provide a longitudinal channel communicating with the exterior surface of said longitudinal wall a longitudinal opening to the exterior of said cylindrical member to form a longitudinal opening therein permitting each said re-entrant portion to be wrapped around an elongate object; and, support means insertable into an end of said cylindrical member, said support means being so formed that in use it bears against the inner surface of said longitudinal well to provide a substantially rigid internal support for at least part of said longitudinal wall of said cylindrical member, said support means including a bridging portion corresponding to each said longitudinal opening and in use lying across each said longitudinal opening to bridge and hold closed each said longitudinal opening.
Claim 2
Dependent Claim
142 words
A cable sleeve outlet comprising: a substantially cylindrical member having at least one re-entrant portion in its longitudinal wall shaped to provide a longitudinal channel communicating with the exterior surface of said longitudinal wall a longitudinal opening to the exterior of said cylindrical member to form a longitudinal opening therein permitting each said re-entrant portion to be wrapped around an elongate object; and, support means insertable into an end of said cylindrical member, said support means being so formed that in use it bears against the inner surface of said longitudinal well to provide a substantially rigid internal support for at least part of said longitudinal wall of said cylindrical member, said support means including a bridging portion corresponding to each said longitudinal opening and in use lying across each said longitudinal opening to bridge and hold closed each said longitudinal opening.
Claim 3
Dependent Claim
49 words
An outlet according to claim 1 wherein said support means is plate-like in form and has at least one slot positioned so that the facing slot edges engage the inner surface of the opposing walls bordering each said longitudinal opening in each said re-entrant portion of said cylindrical member.
Claim 4
Dependent Claim
27 words
An outlet according to claim 2, wherein said support means includes at least one pair of slots which slots respectively engage one each of said opposing walls.
Claim 5
Dependent Claim
27 words
An outlet according to claim 3, wherein the material of said support means which separates the said pair of slots carries material for sealing the closed opening.
Claim 6
Dependent Claim
38 words
An outlet according to claim 3 or 4, wherein the material comprising of the support means which separates the said pair of slots is a continuous integral part of the material forming the rest of said support means.
Claim 7
Dependent Claim
26 words
An outlet according to claim 1, wherein each said re-entrant portion carries material for sealing to the elongate object around which it is wrapped in use.
Claim 8
Dependent Claim
18 words
An outlet according to claim 4 or 6, wherein said material for sealing is a heat activatable adhesive.
Claim 9
Dependent Claim
45 words
An outlet according to any one of claims 1 to 3, wherein said support means is so formed that it bears on and internally supports substantially the whole perimeter of said longitudinal wall which is presented to the outside of said cylindrical member in use.
Claim 10
Dependent Claim
28 words
An outlet according to claim 1, wherein said support means comprises part shells capable of being together to surround a cable passing through the outlet unit in use.
Claim 11
Dependent Claim
51 words
An outlet according to any one of claims 1 to 3, wherein said support means includes a portion which in use projects beyond the end of said cylindrical member which projecting portion is adapted for attachment to support members of a splice case with which the outlet is to be used.
Claim 12
Dependent Claim
20 words
An outlet according to claim 1, wherein the whole of said cylinrical member is made of heat recoverable polymeric material.
Claim 13
Dependent Claim
19 words
An outlet according to any one of claims 1 to 3, wherein said cylindrical member is a moulded article.
Claim 14
Dependent Claim
36 words
An outlet according to any one of claims 1 to 3, wherein said cylindrical member is closed at one end so as to be capable of retaining internal pressure when used in a pressurized splice case.
Claim 15
Dependent Claim
20 words
A cable splice case incorporating a cable sleeve outlet according to any one of claims 1 to 3, and 11.
Claim 16
Dependent Claim
37 words
A splice case according to claim 14, wherein the cylindrical member of the outlet is physically engaged with a projection or depression carried by a co-operating member so as to resist longitudinal sliding of the cylindrical member.
Claim 17
Dependent Claim
135 words
A cable sleeve outlet comprising: a substantially cylindrical member having at least one heat-shrinkable re-entrant portion in its longitudinal wall shaped to provide a longitudinal channel communicating with the exterior surface of said longitudinal wall to form a longitudinal opening therein permitting each said re-entrant portion to be wrapped around and heat-shrunk onto an elongate object; and, support means insertable into an end of said cylindrical member said support means being so formed that in use it bears against the inner surface of said longitudinal wall to provide a substantially rigid internal support for at least part of said longitudinal wall of said cylindrical member, said support means including a bridging portion corresponding to each said longitudinal opening and in use lying across each said longitudinal opening to bridge and hold closed said longitudinal opening.
Claim 18
Dependent Claim
135 words
A cable sleeve outlet comprising: a substantially cylindrical member having at least one heat-shrinkable re-entrant portion in its longitudinal wall shaped to provide a longitudinal channel communicating with the exterior surface of said longitudinal wall to form a longitudinal opening therein permitting each said re-entrant portion to be wrapped around and heat-shrunk onto an elongate object; and, support means insertable into an end of said cylindrical member said support means being so formed that in use it bears against the inner surface of said longitudinal wall to provide a substantially rigid internal support for at least part of said longitudinal wall of said cylindrical member, said support means including a bridging portion corresponding to each said longitudinal opening and in use lying across each said longitudinal opening to bridge and hold closed said longitudinal opening.
