Under-carpet coaxial cable

Claim 2

A thin, flat electrical cable of the type having opposing generally flattened surfaces, the cable comprising: (a) at least one elongated signal conductor; (b) at least two elongated stress-bearing members longitudinally disposed parallel to, spaced apart from, and on opposite sides of, said signal conductor, said two members for bearing stresses resulting from a compressive load applied against the cable opposing surfaces; and (c) a unitary, electrically insulative, pliable jacket means for fixing the transverse relationship of said signal conductor and said stress-bearing members, said means also for affording independent longitudinal movement to said stress-bearing members relative to said jacket means, said jacket means separately enclosing said signal conductor and said stress-bearing members.

Claim 3

An electrical cable, as recited in claim 1 wherein said signal conductor is a coaxial cable.

Claim 4

A thin, flat electrical cable, as recited in claim 1, further including (d) relief shaping means around said signal conductor on the surface of said pliable jacket for diverting away from said signal conductor toward said stress-bearing members a major portion of stresses resulting from a compressive load applied against the cable opening surface.

Claim 5

An electrical cable, as recited in claim 3, wherein said relief shaping means is in the form of a plurality of parallel longitudinal channels.

Claim 6

An electrical cable, as recited in claim 3 or claim 4, wherein said signal conductor is a coaxial cable.

Claim 7

A thin, flat electrical cable for installation between a relatively unyielding floor surface and a relatively yielding floor covering, the cable comprising: (a) a coaxial cable; (b) two stress-bearing members having circular cross sections and being longitudinally disposed parallel to and on opposite sides of said coaxial cable in a spaced-apart relationship therewith; (c) unitary, electrically insulative, pliable jacket means of generally trapezoidal cross section for fixing the transverse relationship among said and said coaxial cable stress-bearing members, said means also for affording independent longitudinal movement to said stress-bearing members relative to said jacket means, said jacket means separately enclosing said coaxial cable and said stress-bearing members; and (d) relief shaping means in the form of a plurality of parallel longitudinal channels around said coaxial cable on the surface of said pliable jacket for diverting away from said coaxial cable toward said stress-bearing members a major portion of any vertically compressive load applied to said thin, flat cable as installed.

Claim 8

A thin, flat electrical cable for installation between a relatively unyielding floor surface and a relatively yielding floor covering, the cable comprising: (a) a coaxial cable; (b) two stress-bearing members having circular cross sections and being longitudinally disposed parallel to and on opposite sides of said coaxial cable in a spaced-apart relationship therewith; (c) unitary, electrically insulative, pliable jacket means of generally trapezoidal cross section for fixing the transverse relationship among said and said coaxial cable stress-bearing members, said means also for affording independent longitudinal movement to said stress-bearing members relative to said jacket means, said jacket means separately enclosing said coaxial cable and said stress-bearing members; and (d) relief shaping means in the form of a plurality of parallel longitudinal channels around said coaxial cable on the surface of said pliable jacket for diverting away from said coaxial cable toward said stress-bearing members a major portion of any vertically compressive load applied to said thin, flat cable as installed.

Claim 9

An electrical cable, as recited in any one of claim 1, claim 3, claim 5, or claim 6, wherein: (a) said jacket means is composed of flexible polyvinylchloride; and (b) said stress-bearing members are composed of solid nylon.

Claim 10

An electrical cable, as recited in claim 7, wherein said coaxial cable contains a dielectric composed of expanded polytetrafluoroethylene.

Claim 11

An electrical cable as recited in claim 8 having a thickness of about 0.080 inch.
