Abstract
Abstract Disclosed is a cable seal for use primarily in aerial closures and terminals. The seal includes a pair of compliant elements with their major surfaces in contact. Each element includes a series of rings attached by a thin web of material so that rings can be removed to accommodate different cable sizes. A slit extends radially from the center ring to permit installation of the elements over the cable. The slits of the two elements are arranged out of alignment to ensure that no gaps in the seal exist at the slits.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
Apparatus for enclosing a cable comprising: a housing including at least one surface adapted to permit a cable to pass therethrough; and compliant means adjacent to at least one end surface, said means comprising a compliant member with integral front and back sections having substantially flat major surfaces in intimate contact prior to installation over a cable, each section including at least one removable ring in said major surfaces and at least one radial slit extending through said ring to an edge of each major surface, the slits of the two sections being sufficiently out of alignment to prevent any significant penetration of contaminants through said major surfaces, and the member being installable on a cable by opening both slits sufficiently to permit a cable to pass through the resulting opening formed in both sections of the member.
Claim 2
Dependent Claim
138 words
Apparatus for enclosing a cable comprising: a housing including at least one surface adapted to permit a cable to pass therethrough; and compliant means adjacent to at least one end surface, said means comprising a compliant member with integral front and back sections having substantially flat major surfaces in intimate contact prior to installation over a cable, each section including at least one removable ring in said major surfaces and at least one radial slit extending through said ring to an edge of each major surface, the slits of the two sections being sufficiently out of alignment to prevent any significant penetration of contaminants through said major surfaces, and the member being installable on a cable by opening both slits sufficiently to permit a cable to pass through the resulting opening formed in both sections of the member.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1 wherein the slits are approximately 180 degrees out of alignment.
Claim 4
Dependent Claim
24 words
Apparatus according to claim 1 wherein the sealing member comprises a material selected from the group consisting of a foam, silicone, rubber, and urethane.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 1 wherein a hole is formed in the said major surfaces and the hole is less than the diameter of the cable so that a gap is formed by each slit.
Claim 6
Independent Claim
127 words
A device for sealing cables comprising a compliant member with integral front and back sections having substantially major surfaces in intimate contact prior to installing over a cable, each section including at least one removable ring for forming a variable hole diameter in said surfaces and at least one radial slit extending through said ring to an edge of each surface, the slits of the two sections being sufficiently out of alignment to prevent any significant penetration of contaminants through said surfaces when said device is installed on a cable in combination with a housing adjacent thereto, and the member being installable on a cable by opening both slits sufficiently to permit the cable to pass through the resulting opening formed in both sections of the member.
Claim 7
Independent Claim
127 words
A device for sealing cables comprising a compliant member with integral front and back sections having substantially major surfaces in intimate contact prior to installing over a cable, each section including at least one removable ring for forming a variable hole diameter in said surfaces and at least one radial slit extending through said ring to an edge of each surface, the slits of the two sections being sufficiently out of alignment to prevent any significant penetration of contaminants through said surfaces when said device is installed on a cable in combination with a housing adjacent thereto, and the member being installable on a cable by opening both slits sufficiently to permit the cable to pass through the resulting opening formed in both sections of the member.
Claim 8
Dependent Claim
16 words
The device according to claim 5 wherein the slits are approximately 180 degrees out of alignment.
Claim 9
Dependent Claim
24 words
The device according to claim 5 wherein the compliant member comprises a material selected from the group consisting of foam, silicone, rubber, and urethane.
