Abstract
Abstract Disclosed herein is a cable splice assembly in which a stripped end portion of the cable is enclosed in a plastic domelike container, said domelike container being in sealing engagement by means of a first type seal with a sealing chamber. This sealing chamber encloses not only the unstripped portion of said cable but also a plasticlike substance within a closed space to form a second type seal. Provisions are made for producing compressive forces on such plasticlike substance, to drive it thoroughly into engagement with the unstripped cable surfaces as well as the interior surfaces of the sealing chamber that encloses such plasticlike substance so as to produce a tight and gasproof seal of a second type against the unstripped cable surface and the inner surface of the sealing chamber enclosure. By means of such a two seal assembly, ready access can thus be had to the stripped cable portion through said first seal means without breaking the last mentioned seal.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
240 words
A splice case receiving and protecting portions of cable sections comprising: a. a domelike container wherein there is formed at an open end thereof an outwardly extending external face plate; b. means defining a sealing chamber having two open ends, one end having formed thereon a face plate complementary with the face plate of said domelike container, said sealing chamber being formed near its other end with an internal annulus protruding inwardly from the internal surface of said sealing chamber and constituting an abutment, said means defining said sealing chamber being in removable, sealing engagement with said domelike container; and, c. a composite formed of first, second and third spaced apart disc means all strung on a means adapted to move said first, second and third disc means in a closer relationship one to another, said first disc means being disposed on one side of said internal annulus, said second disc means being disposed on the opposite side of said internal annulus, said third disc means being spaced apart from said internal annulus and forming a compression compartment in combination with said second disc means and said sealing chamber, wherein said compression compartment contains a body of deformable sealing material, essentially filling said compartment, and each of said disc means having openings therein through which said portions of said cable sections extend, with said sealing material forming a seal around the portions of said cable sections extending through said compartment.

Claim 4
Dependent Claim
37 words
The splice case defined in claim 1, wherein the body of sealing material comprises a material which has a high internal molecular resistance, is deformable under compressive force, is substantially nonelastic, and is of a high viscosity.
Claim 5
Dependent Claim
13 words
The splice case defined in claim 3, wherein the sealing material comprises polyisobutylene.
Claim 6
Dependent Claim
35 words
The splice case defined in claim 4 wherein said sealing material is highly self-adhesive, and when portions of such material contact with each other under compressive forces, a substantially integral body of material is produced.
Claim 7
Dependent Claim
28 words
The splice case defined in claim 1, wherein the domelike container, said means defining sealing chamber, and each of said disc means are composed of a plastic material.
Claim 8
Dependent Claim
44 words
The splice case defined in claim 1, wherein the plastic material forming the sealing chamber is slightly adhesive to the body of said sealing material disposed in the compression compartment, and is more strongly adhesive to said body of said sealing material under shear.
Claim 9
Dependent Claim
23 words
The splice case defined in claim 1, wherein said means defining the sealing chamber and each of said disc means comprises polyvinyl chloride.
Claim 10
Dependent Claim
38 words
The splice case defined in claim 1, wherein an O-ring made of deformable material is disposed in U-shaped grooves formed in the face plates of both said sealing chamber and said domelike container to provide a seal therebetween.
