Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A printed circuit card of the type having a plurality of electrical components mounted on a face thereof and a plurality of circuit traces on a face thereof that serve to connect various ones of the plurality of electrical components to a plurality of elongated finger contacts at a plurality of finger contact positions adjacent a connector edge of said printed circuit card, the improvement comprising a modified finger contact spanning a selected finger contact position and an immediately adjacent finger contact position, said modified finger contact formed to have an elongated member and having a connected leg member extending outwardly from said elongated member at an end of said elongated member that is nearest said connector edge, said leg member extending into an area defined by said immediately adjacent finger contact position.
Claim 2
Dependent Claim
133 words
A printed circuit card of the type having a plurality of electrical components mounted on a face thereof and a plurality of circuit traces on a face thereof that serve to connect various ones of the plurality of electrical components to a plurality of elongated finger contacts at a plurality of finger contact positions adjacent a connector edge of said printed circuit card, the improvement comprising a modified finger contact spanning a selected finger contact position and an immediately adjacent finger contact position, said modified finger contact formed to have an elongated member and having a connected leg member extending outwardly from said elongated member at an end of said elongated member that is nearest said connector edge, said leg member extending into an area defined by said immediately adjacent finger contact position.
Claim 3
Dependent Claim
199 words
A printed circuit card for causing a momentary shorting together of two adjacent receptacle contacts within a mating receptacle connector whenever said printed circuit card is plugged into or removed from said mating receptacle connector, the printed circuit card comprising: edge connector means comprising a plurality of generally parallel elongated finger contacts located at a plurality of finger contact positions adjacent a connector edge of said printed circuit card for separately contacting a corresponding plurality of receptacle contacts within said mating receptacle connector; a modified finger contact spanning a selected finger contact position and an immediately adjacent finger contact position, said modified finger contact being formed to comprise an elongated member and a connected leg member extending outwardly from said elongated member at an end of said elongated member that is nearest said connector edge of said printed circuit card, said leg member extending into an area defined by said immediately adjacent finger contact position, whereby said leg member momentarily contacts two adjacent receptacle contacts within said mating receptacle connector corresponding to said selected finger contact position and said imediately adjacent finger contact position when said printed circuit card is plugged into or removed from said mating receptacle connector.
Claim 4
Dependent Claim
199 words
A printed circuit card for causing a momentary shorting together of two adjacent receptacle contacts within a mating receptacle connector whenever said printed circuit card is plugged into or removed from said mating receptacle connector, the printed circuit card comprising: edge connector means comprising a plurality of generally parallel elongated finger contacts located at a plurality of finger contact positions adjacent a connector edge of said printed circuit card for separately contacting a corresponding plurality of receptacle contacts within said mating receptacle connector; a modified finger contact spanning a selected finger contact position and an immediately adjacent finger contact position, said modified finger contact being formed to comprise an elongated member and a connected leg member extending outwardly from said elongated member at an end of said elongated member that is nearest said connector edge of said printed circuit card, said leg member extending into an area defined by said immediately adjacent finger contact position, whereby said leg member momentarily contacts two adjacent receptacle contacts within said mating receptacle connector corresponding to said selected finger contact position and said imediately adjacent finger contact position when said printed circuit card is plugged into or removed from said mating receptacle connector.
