Abstract

Abstract The present invention relates to manufacture of electrical conductors by winding small gauge wires helically on a drum, bonding the wires to a flexible sheet of polymeric material also wrapped on the drum, and stripping from the drum the composite of wires and polymeric material that form an array of flat, spring resilient, lengths of substantially parallel conductors.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 95 words
A method for fabricating a sheet of isolated metal conductors, comprising the steps of: winding a conductive round wire in a helix having spaced apart coils over a grooved cylindrical drum, wrapping over the coils a sheet of flexible polymeric material having a layer of adhesive between and adhering to the coils and the sheet, applying pressure to the sheet, severing the sheet and the coils, stripping from the drum a composite of the sheet and the severed coils, and flattening the coils and the sheet to provide an array of parallel, closely spaced conductors.
Claim 2
Independent Claim 95 words
A method for fabricating a sheet of isolated metal conductors, comprising the steps of: winding a conductive round wire in a helix having spaced apart coils over a grooved cylindrical drum, wrapping over the coils a sheet of flexible polymeric material having a layer of adhesive between and adhering to the coils and the sheet, applying pressure to the sheet, severing the sheet and the coils, stripping from the drum a composite of the sheet and the severed coils, and flattening the coils and the sheet to provide an array of parallel, closely spaced conductors.
Claim 3
Dependent Claim 45 words
The method as recited in claim 1, wherein the groove is a helical groove of a depth less than the diameter of the wire, and further including the steps of, holding the wire in the helical groove while partially imbedding the wire in the adhesive.
Claim 4
Dependent Claim 34 words
The method as recited in claim 1, wherein the wire is selected with metal spring properties, and further including the step of, stamping and forming the composite into one or more three-dimensional electrical connectors.
Claim 5
Independent Claim 34 words
The method as recited in claims 1 or 2 or 3, and further including the steps of, displacing the layer of adhesive with the imbedded coils, and engaging the imbedded coils against the sheet.
Claim 6
Dependent Claim 27 words
The methods as recited in claims 1 or 2 or 3 in which more than one-half the peripheries of the round conductors are embedded in the adhesive.
Claim 7
Dependent Claim 126 words
At method for fabricating a sheet of isolated metal conductors, comprising the steps of: winding a conductive ground wire in a helix having spaced apart coils over a helically grooved cylindrical drum wherein the helical groove has a depth less than the diameter of the wire, wrapping over the coils a sheet of flexible polymeric material having a layer of adhesive between and adhering to the coils and the sheet wherein the wire is held in the helical groove while being partially embedded in the adhesive, applying pressure to the sheet, severing the sheet and the coils, stripping from the drum a composite of the sheet and the severed coils and flattening the coils and the sheet to provide an array of parallel, closely spaced conductors.
Claim 8
Dependent Claim 126 words
At method for fabricating a sheet of isolated metal conductors, comprising the steps of: winding a conductive ground wire in a helix having spaced apart coils over a helically grooved cylindrical drum wherein the helical groove has a depth less than the diameter of the wire, wrapping over the coils a sheet of flexible polymeric material having a layer of adhesive between and adhering to the coils and the sheet wherein the wire is held in the helical groove while being partially embedded in the adhesive, applying pressure to the sheet, severing the sheet and the coils, stripping from the drum a composite of the sheet and the severed coils and flattening the coils and the sheet to provide an array of parallel, closely spaced conductors.
