Abstract
Abstract An underground connector housing for large diameter power lines is enclosed within a split housing comprised of upper and lower Fiberglas reinforced plastic shells. These shells have entrance and exit ports for receiving the power cables which are connected together inside the housing. Gaskets seal the housing by following the contours of the mating surfaces on each shell of the Fiberglas housing. At the ports, the gaskets are increased slightly in thickness. Hence, the compression forces which occur when the two parts are bolted together, squeeze the gaskets together to force them to expand and fill all of the available space within the housing parts and around the cables.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
26 words
A connector housing as claimed in claim 1, wherein said rib means comprise a plurality of parallel ribs positioned to sealingly contact cables within said ports.
Claim 2
Dependent Claim
23 words
A housing as claimed in claim 1, wherein said rib means comprise a plurality of arcuate ribs in each of said port arches.
Claim 3
Dependent Claim
203 words
A moisture sealing, rigid connector housing for underground use, comprising upper and lower shells adapted to be joined together, raised wall members within each of said shells defining a continuous recess completely surrounding the central portion of said housing, each of said shells having ports within said wall member for providing an entrance into the central portion of said housing for electrical cables, and at least one endless, noncompressible gasket member resting within each recess positioned to bear against the gasket member of the adjoining shell, each of said gasket members arched within said cable ports to bear against such cables on joinder of said shells to one another, the width of each gasket member being substantially less than the width of said recess and the height of each of said gasket members being greater than the depth of said recess, wherein said gasket members are fabricated of material substantially resistant to compression and having elastic qualities to deform outwardly into said recess on joining together tightly of said shells, and wherein there are a plurality of arcuate ribs extending from said gasket member within each of said arched portions to sealingly contact the cables on joinder of the shells and gasket members.
