Abstract
Abstract A printed wiring card assembly in which electronic components can be plugged in to mechanically mount and electrically interconnect into the assembly, including a flexible printed wiring sheet held in resilient contact between a component positioner and ridges on a support base. The positioner includes slots and a guide ramp for guiding the component leads insertable between the positioner and conductive connecting portions on the printed wiring sheet. A layer of resilient material on the ridges urges the conductive connecting portions into resilient contact engagement with the component leads.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
An electronic printed wiring card assembly for mounting and electrically interconnecting electronic components comprising: a support base card having alternating spacially separated longitudinal ridges and cavities on at least one surface thereof; a layer of resilient material attached to each of said ridges on said base card; a flexible printed wiring sheet extending over said ridges and into said cavities on said base card; conductive strips on one surface of said flexible sheet defining an electrical wiring pattern; said conductive strips including connector receptacle portions immediately adjacent said ridges; and a plurality of positioner members each overlying said flexible sheet in respective cavities; said positioner members each sized to define a resilient contact engagement urged by said resilient member between said connector receptacle portions and said positioner member along a surface junction therebetween for electrically connecting said electronic components to said connector receptacle portions and mechanically mounting said components upon insertion of said electronic components in said assembly.
Claim 2
Dependent Claim
158 words
An electronic printed wiring card assembly for mounting and electrically interconnecting electronic components comprising: a support base card having alternating spacially separated longitudinal ridges and cavities on at least one surface thereof; a layer of resilient material attached to each of said ridges on said base card; a flexible printed wiring sheet extending over said ridges and into said cavities on said base card; conductive strips on one surface of said flexible sheet defining an electrical wiring pattern; said conductive strips including connector receptacle portions immediately adjacent said ridges; and a plurality of positioner members each overlying said flexible sheet in respective cavities; said positioner members each sized to define a resilient contact engagement urged by said resilient member between said connector receptacle portions and said positioner member along a surface junction therebetween for electrically connecting said electronic components to said connector receptacle portions and mechanically mounting said components upon insertion of said electronic components in said assembly.
