Abstract
Abstract A tubular member having an O-ring seal on a shoulder is locked in a panel opening with a nut. An elastomeric sleeve is bonded to an extended sleeve portion of the tubular member. Two elastomeric mirror image inserts forming one or more fiber optic cable cavities are assembled around the cables and inserted into engagement with the elastomeric sleeve internal surface. A hose clamp compresses the elastomeric sleeve against the elastomeric elements, firmly clamping the elements and the cables in place.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A panel seal and support structure for a fiber optic cable passing through an opening in said panel comprising: a tubular member having first and second ends; means for securing said first end of the tubular member to said panel at said opening; an elastomeric sleeve secured to said second end; first and second elastomeric elements abutting along mating facing surfaces and closely received in said sleeve, the interface of said surfaces forming at least one aperture of a given dimension for closely receiving said cable; and clamp means engaged with said sleeve for clamping said sleeve to said elements and compressing the elements to frictionally engage the received cable.
Claim 2
Dependent Claim
110 words
A panel seal and support structure for a fiber optic cable passing through an opening in said panel comprising: a tubular member having first and second ends; means for securing said first end of the tubular member to said panel at said opening; an elastomeric sleeve secured to said second end; first and second elastomeric elements abutting along mating facing surfaces and closely received in said sleeve, the interface of said surfaces forming at least one aperture of a given dimension for closely receiving said cable; and clamp means engaged with said sleeve for clamping said sleeve to said elements and compressing the elements to frictionally engage the received cable.
Claim 3
Dependent Claim
21 words
The structure of claim 1 wherein said means for securing includes means for hermetically sealing said tubular member to said panel.
Claim 4
Dependent Claim
20 words
The structure of claim 1 wherein said sleeve is bonded to said second end to form a hermetic seal thereto.
Claim 5
Dependent Claim
22 words
The structure of claim 1 wherein said first and second elastomeric elements form a plurality of cable receiving apertures at said interface.
Claim 6
Dependent Claim
160 words
A panel seal and support structure for a fiber optic cable passing through an opening in said panel comprising: a hollow member having a threaded exterior surface at one end adapted to pass through said opening, and a cylindrical sleeve portion at a second end opposite the one end, said member having an annular portion between said ends of greater diameter than said threaded exterior surface forming a shoulder which is adapted to abut a surface of said panel when said threaded surface passes through said opening; an elastomeric sleeve secured to said sleeve portion of said member; first and second elastomeric members closely received within said elastomeric sleeve, said elastomeric members abutting along facing surfaces thereof, said facing surfaces forming at least one opening for closely receiving a portion of said fiber optic cable; and clamp means engaged with said elastomeric sleeve for resiliently clamping said sleeve against said elastomeric members and said elastomeric members against said received cable.
Claim 7
Dependent Claim
160 words
A panel seal and support structure for a fiber optic cable passing through an opening in said panel comprising: a hollow member having a threaded exterior surface at one end adapted to pass through said opening, and a cylindrical sleeve portion at a second end opposite the one end, said member having an annular portion between said ends of greater diameter than said threaded exterior surface forming a shoulder which is adapted to abut a surface of said panel when said threaded surface passes through said opening; an elastomeric sleeve secured to said sleeve portion of said member; first and second elastomeric members closely received within said elastomeric sleeve, said elastomeric members abutting along facing surfaces thereof, said facing surfaces forming at least one opening for closely receiving a portion of said fiber optic cable; and clamp means engaged with said elastomeric sleeve for resiliently clamping said sleeve against said elastomeric members and said elastomeric members against said received cable.
Claim 8
Dependent Claim
26 words
The structure of claim 5 wherein said elastomeric members form a cylindrical element, said element including a shoulder portion abutting an edge of said elastomeric sleeve.
Claim 9
Dependent Claim
31 words
The structure of claim 5 wherein said shoulder has an annular groove, said structure further including sealing means in and extending from said groove for sealing engagement with said panel surface.
Claim 10
Dependent Claim
25 words
The structure of claim 5 wherein said elastomeric sleeve is bonded to said sleeve portion of said hollow member to form a hermetic seal therebetween.
