Abstract

Abstract A terminated multiconductor flat flexible printed circuit cable and its production are disclosed. The insulation is stripped from one side of one end of the cable to expose portions of the conductors, the cable is folded back on itself intermediate the exposed conductor portions, the cable is adhesively bonded to a connector board with the exposed conductors in registration with the connector terminations and the folded conductor portions are passed through a wave of solder.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 159 words
A terminated printed circuit comprising: a flat flexible printed circuit having a plurality of conductors extending to one edge thereof, said conductors being substantially parallel adjacent said one edge and being exposed on one side along a first length extending from said one edge, said circuit being folded on itself intermediate said first length to provide first and second layers of exposed conductive material; a rigid connector board having a plurality of conductive portions on one side thereof, said conductive portions being aligned with said first layer of exposed conductive material on said one side of said circuit and said second layer of conductive material being spaced from said board outwardly of said first layer; means attaching said circuit to said board along a second length of said circuit, said second length being disposed inwardly from said one edge and said first length; and means electrically connecting said board conductive portions and said exposed portions of said circuit conductors.
Claim 2
Dependent Claim 159 words
A terminated printed circuit comprising: a flat flexible printed circuit having a plurality of conductors extending to one edge thereof, said conductors being substantially parallel adjacent said one edge and being exposed on one side along a first length extending from said one edge, said circuit being folded on itself intermediate said first length to provide first and second layers of exposed conductive material; a rigid connector board having a plurality of conductive portions on one side thereof, said conductive portions being aligned with said first layer of exposed conductive material on said one side of said circuit and said second layer of conductive material being spaced from said board outwardly of said first layer; means attaching said circuit to said board along a second length of said circuit, said second length being disposed inwardly from said one edge and said first length; and means electrically connecting said board conductive portions and said exposed portions of said circuit conductors.
Claim 3
Dependent Claim 35 words
The article of claim 1 wherein said electrical connecting means comprises: solder joining said conductors and portions, said solder being disposed between said conductors and portions and covering the folded over portion of said conductors.
Claim 4
Dependent Claim 20 words
The article of claim 2 wherein said solder forms a fillet about the exposed conductors where said circuit is folded.
Claim 5
Dependent Claim 26 words
The article of claim 3 wherein said attaching means comprises: means adhesively bonding said circuit to said board along a strip parallel to said one edge.
Claim 6
Dependent Claim 26 words
The article of claim 1 wherein said attaching means comprises: means adhesively bonding said circuit to said board along a strip parallel to said one edge.
Claim 7
Independent Claim 142 words
A method for electrically and mechanically joining a flexible cable to a rigid connector, said cable comprising at least one conductor having substantially flat surfaces encapsulated by insulating material and said connector comprising a rigid insulator having at least a first conductive termination on a surface thereof, said method comprising the sequential steps of: removing the insulation from one surface of said cable conductor along a first length adjacent a first end of said cable; folding the cable back on itself intermediate said first length to present said exposed side of said conductor on both sides of the cable; aligning said exposed conductor portion which is in the plane of said cable conductor with said connector termination; affixing said cable to said connector in a region displaced from said first cable length; and soldering said exposed cable conductor to said connector termination.
Claim 8
Independent Claim 142 words
A method for electrically and mechanically joining a flexible cable to a rigid connector, said cable comprising at least one conductor having substantially flat surfaces encapsulated by insulating material and said connector comprising a rigid insulator having at least a first conductive termination on a surface thereof, said method comprising the sequential steps of: removing the insulation from one surface of said cable conductor along a first length adjacent a first end of said cable; folding the cable back on itself intermediate said first length to present said exposed side of said conductor on both sides of the cable; aligning said exposed conductor portion which is in the plane of said cable conductor with said connector termination; affixing said cable to said connector in a region displaced from said first cable length; and soldering said exposed cable conductor to said connector termination.
Claim 9
Dependent Claim 25 words
The method of claim 6 wherein said step of soldering comprises: passing said folded portion of said cable conductor through a wave of molten solder.
Claim 10
Dependent Claim 35 words
The method of claim 7 wherein said step of affixing the cable to the connector comprises: adhesively bonding said cable to said connector along a strip displaced inwardly on said cable from said first length.
Claim 11
Dependent Claim 33 words
The method of claim 8 wherein the step of adhesively bonding comprises: disposing a strip of adhesive between said cable and connector; and curing said adhesive through the application of heat and pressure.
Claim 12
Dependent Claim 35 words
The method of claim 6 wherein said step of affixing the cable to the connector comprises: adhesively bonding said cable to said connector along a strip displaced inwardly on said cablE from said first length.
