Abstract:

This invention relates to a pressurized telecommunication cable joint closure method and apparatus. Provided is a cylinder comprising a pair of semicylindrical shell members connected together along one elongate edge of each member and releasable securing means on the other elongate edge of each member. The securing means comprises a plurality of projections on one member edge and a matching plurality of receiving means on the other member edge whereas the projections extend radially inward and lie within a plane containing the longitudinal axis of one of the shell members. The cylinder further has interleaved rectilinear fingers at the ends that are for sealing to joined cables. A heat shrinkable wraparound member is used to enclose the cylinder and joined cables.

Abstract:

A reenterable splice closure and method of making and applying the same is disclosed having a pair of mating housings with an internal rigid telescoping support collar located at the seam between the two housings, and a first heat shrinkable sleeve surrounding and sealably shrunk down over the mating ends of the housings sealing the seam and extending the end of one housing for heat shrinking down onto cables leading from a splice enclosed in the housing. The enclosure can be reopened by cutting the splice along a line over the seam, and after the closure has been reassembled with the housings again in mating position, a new heat shrinkable sleeve is applied down over the cut in the first shrinkable sleeve.
