Abstract
Abstract Disclosed is a flat cable incorporating an elongated, bendable protective structure which is comprised of a central channel member of rigid cross-section for resisting forces applied to a centrally disposed insulated conductor and at least one outer channel member of substantially lesser rigidity for resisting insulation-disruptive forces which may be applied to an insulated conductor adjacent one edge of the cable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
An improved electrical cable comprising: a plurality of elongated electrical conductors having substantially parallel spaced apart axes, lying substantially in one plane, electrical insulation surrounding individual ones of said conductors for electrically insulating each of said conductors; a first and second discrete elongated member each having a first leg portion lying substantially parallel to the one plane and extending toward and adjacent the outermost surface of the insulation covering a different one of the conductors, said first and second members each having a second leg portion lying substantially parallel to a second plane substantially perpendicular to said one plane and joined to a respective one of a first leg portion; the second leg portions of said first and second members being less compressible in directions parallel to said second plane than the insulating material on the adjacent one of the conductors and the cross-sectional dimension of said second leg portion of said first member being greater than the cross-sectional dimension of said second leg portion of said second member; and a jacket surrounding said first and second members.
Claim 2
Dependent Claim
178 words
An improved electrical cable comprising: a plurality of elongated electrical conductors having substantially parallel spaced apart axes, lying substantially in one plane, electrical insulation surrounding individual ones of said conductors for electrically insulating each of said conductors; a first and second discrete elongated member each having a first leg portion lying substantially parallel to the one plane and extending toward and adjacent the outermost surface of the insulation covering a different one of the conductors, said first and second members each having a second leg portion lying substantially parallel to a second plane substantially perpendicular to said one plane and joined to a respective one of a first leg portion; the second leg portions of said first and second members being less compressible in directions parallel to said second plane than the insulating material on the adjacent one of the conductors and the cross-sectional dimension of said second leg portion of said first member being greater than the cross-sectional dimension of said second leg portion of said second member; and a jacket surrounding said first and second members.
Claim 3
Dependent Claim
47 words
The cable according to claim 1 wherein each of said first and second members has a third leg portion joined to a respective one of said second leg portions, each said third portion extending substantially parallel to a first leg portion having a common second leg portion.
Claim 4
Dependent Claim
41 words
The cable according to claim 2 wherein said first and third leg portions extend in the same direction from a common one of said second leg portions, whereby each of said first and second members are of substantially U cross-sectional shape.
Claim 5
Dependent Claim
16 words
The cable according to claim 3 wherein said first and second members are rigid in cross-section.
Claim 6
Dependent Claim
64 words
The cable according to claims 1 or 3 wherein there are three of said conductors and a pair of the first members and a pair of the second members, the second members partially enclosing the insulation on different ones of the outermost two conductors and the pair of said first members at least partially enclosing the insulation on opposite portions of the innermost conductor.
Claim 7
Dependent Claim
25 words
The cable according to claim 1 wherein said first and second members have greater thermal conductivity than that of the electrical insulation on said conductors.
Claim 8
Dependent Claim
30 words
The cable according to claim 5 wherein said first leg portion of said first member has a greater cross-section than that of said first leg portion of said second member.
Claim 9
Dependent Claim
28 words
The cable according to claim 7 wherein said second leg portion of said first member has a greater cross-section than said second leg portion of said second member.
Claim 10
Dependent Claim
22 words
The cable according to claim 4 wherein the cross-sectional rigidity of said first member is greater than that of said second member.
