Abstract
Abstract A cable strain relief device comprises a cable manifold having a pair of generally planar surfaces upon opposite sides thereof formed with a plurality of cable receiving channels extending generally lengthwise along the surfaces. The channels are spaced from one another transversely of the length of the manifold and are formed so as to undulate transversely in a serpentine manner to provide strain relief for cables such as fiber optic cables placed in the channels. The channels are sufficiently deep to permit the placement of two cables in each channel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A cable strain relief device comprising a cable manifold having a pair of opposite ends and a generally planar surface extending between said ends, said surface being formed with a plurality of cable-receiving channels extending generally in a first direction along said surface between said ends and spaced from one another in a second direction along said surface normal to said first direction, said channels being so formed in said surface as to undulate in said second direction to provide strain relief for cables placed in said channels.
Claim 2
Dependent Claim
88 words
A cable strain relief device comprising a cable manifold having a pair of opposite ends and a generally planar surface extending between said ends, said surface being formed with a plurality of cable-receiving channels extending generally in a first direction along said surface between said ends and spaced from one another in a second direction along said surface normal to said first direction, said channels being so formed in said surface as to undulate in said second direction to provide strain relief for cables placed in said channels.
Claim 3
Dependent Claim
30 words
A device as in claim 1 in which said manifold has a pair of generally planar surfaces on opposite sides thereof, each of said surfaces being formed with cable-receiving channels.
Claim 4
Dependent Claim
25 words
A device as in claim 1 in which each of said channels has a predetermined width and a depth at least twice said predetermined width.
Claim 5
Dependent Claim
18 words
A device as in claim 1 further comprising a cover adapted to mate with said generally planar surface.
Claim 6
Dependent Claim
16 words
A device as in claim 4 including means for detachably securing said cover to said manifold.
Claim 7
Dependent Claim
16 words
A device as in claim 5 in which said cover is slidable relative to said manifold.
Claim 8
Dependent Claim
20 words
A device as in claim 1 in which said channels are provided with teeth for gripping a cable placed therein.
Claim 9
Dependent Claim
19 words
A device in claim 1 in which said channels are formed with undulations that are aligned with one another.
