Abstract
Abstract A flat electrical power-carrying pod for inclusion as a component in a ribbon cable comprising a multiplicity of parallel wires insulated as a unit by polytetrafluoroethylene and having on each side of the plane of wires a layer of hard cut-through resistant film not contacting the other hard polymer layer. Polyimide is the preferred hard polymer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A signal carrying flat ribbon cable having a flat, generally planar power pod as a component thereof, wherein the power pod comprises from inside to outside: (a) a multiplicity of uninsulated electrically conducting wires arranged in generally parallel planar physical and electrical contact with one another along their axes surrounded by a first layer of polytetrafluororethylene insulation; (b) a layer on each side of said multiplicity of generally parallel planar wires of a hard cut-through resistant polymer, said cut-through resistant polymer layers being separated from each other along their edges by polytetrafluororethylene insulation; and (c) a second layer of polytetrafluoroethylene insulation surrounding said cut-through resistant polymer layers, said wires, and said first layer of polytetrafluororethylene insulation surrounding said wires and including a web, said second layer of polytetrafluoroethylene insulation connecting said power pod to an adjacent component of said ribbon cable by means of the web.
Claim 2
Dependent Claim
146 words
A signal carrying flat ribbon cable having a flat, generally planar power pod as a component thereof, wherein the power pod comprises from inside to outside: (a) a multiplicity of uninsulated electrically conducting wires arranged in generally parallel planar physical and electrical contact with one another along their axes surrounded by a first layer of polytetrafluororethylene insulation; (b) a layer on each side of said multiplicity of generally parallel planar wires of a hard cut-through resistant polymer, said cut-through resistant polymer layers being separated from each other along their edges by polytetrafluororethylene insulation; and (c) a second layer of polytetrafluoroethylene insulation surrounding said cut-through resistant polymer layers, said wires, and said first layer of polytetrafluororethylene insulation surrounding said wires and including a web, said second layer of polytetrafluoroethylene insulation connecting said power pod to an adjacent component of said ribbon cable by means of the web.
Claim 3
Dependent Claim
12 words
A power pod of claim 1 wherein the polytetrafluoroethylene is porous polytetrafluoroethylene.
Claim 4
Dependent Claim
14 words
A power pod of claim 1 wherein said cut-through resistant polymer comprises polyimide polymer.
Claim 5
Dependent Claim
13 words
A power pod of claim 3 wherein said polyimide polymer is fully cured.
Claim 6
Dependent Claim
26 words
A power pod of claim 1 wherein at least one side of each layer of said cut-through resistant polymer is coated with a layer of adhesive.
Claim 7
Dependent Claim
22 words
A power pod of claim 1 wherein at least one of said cut-through resistant polymer layers is coated with a metal layer.
Claim 8
Dependent Claim
15 words
A power pod of claim 5 wherein said adhesive is a high-temperature resistant thermoplastic polymer.
Claim 9
Dependent Claim
28 words
A power pod of claim 7 wherein said thermoplastic polymer is selected from the group perfluorinated ethylene-propylene copolymer, perfluoroalkoxy tetrafluoroethylene, polyvinylidene fluoride, and copolymer of ethylene and tetrafluoroethylene.
