Abstract
Abstract Apparatus incorporating a novel three-dimensional systems packaging technique facilitating the implementation of direct electrical interconnections between a plurality of printed circuit cards thereby eliminating the routing of electrical signal paths to the card edges. The apparatus basically comprises a plurality of connector cards having contact means mounted thereon for establishing electrical connections directly therethrough. As the printed circuit cards are interleaved between the connector cards, the contacts slide on a track correspondingly disposed on the circuit cards. After insertion, the circuit cards are displaced, e.g., downward, so that the contacts slide from the tracks onto corresponding circuit access points disposed adjacent to the tracks, establishing an electrical connection between the adjacent circuit cards. Platedthrough holes are also provided to interconnect circuit access points on opposite sides of the circuit card.

Claim 1
Independent Claim
250 words
Apparatus for electrically interconnecting selected circuit signal points on adjacently positioned printed circuit cards and on a plurality of printed circuit cards comprising: a plurality of connector cards; contact means including connector contacts mounted on each of said connector cards and extending between said circuit cards for establishing a direct electrical connection between adjacent ones of said circuit cards; track means on said circuit cards for engaging and carrying said connector contacts as said circuit cards are positioned adjacent to and on opposite sides of said contact means; and said connector contacts are arranged in rows across each of said connector cards parallel to the direction in which said circuit cards are interleaved between said connector cards and wherein said track means comprises hard insulative strips disposed across both sides of said circuit cards to correspond to said connector contact rows on said connector cards, said connector contacts sliding on said strips as said circuit cards are inserted between said connector cards; circuit access means disposed on each of said circuit cards adjacent to said track means and coupled to corresponding ones of said selected signal points; and conductor means extending through said circuit cards for electrically interconnecting corresponding ones of said circuit access means on opposite sides of said circuit cards, said circuit cards being repositioned after being positioned adjacent to said contact means so that said connector contacts slide from said track means onto said circuit access means to establish a direct electrical connection between said circuit cards.
Claim 2
Dependent Claim
250 words
Apparatus for electrically interconnecting selected circuit signal points on adjacently positioned printed circuit cards and on a plurality of printed circuit cards comprising: a plurality of connector cards; contact means including connector contacts mounted on each of said connector cards and extending between said circuit cards for establishing a direct electrical connection between adjacent ones of said circuit cards; track means on said circuit cards for engaging and carrying said connector contacts as said circuit cards are positioned adjacent to and on opposite sides of said contact means; and said connector contacts are arranged in rows across each of said connector cards parallel to the direction in which said circuit cards are interleaved between said connector cards and wherein said track means comprises hard insulative strips disposed across both sides of said circuit cards to correspond to said connector contact rows on said connector cards, said connector contacts sliding on said strips as said circuit cards are inserted between said connector cards; circuit access means disposed on each of said circuit cards adjacent to said track means and coupled to corresponding ones of said selected signal points; and conductor means extending through said circuit cards for electrically interconnecting corresponding ones of said circuit access means on opposite sides of said circuit cards, said circuit cards being repositioned after being positioned adjacent to said contact means so that said connector contacts slide from said track means onto said circuit access means to establish a direct electrical connection between said circuit cards.
Claim 3
Dependent Claim
99 words
Apparatus in accordance with claim 1 wherein said circuit access means comprises a plurality conductive elements connected to said selected circuit signal points, said conductive elements being positioned adjacent to said strips on both sides of said circuit card and spaced to correspond to said connector contacts, said circuit card being displaced normal to the direction of insertion of said circuit card in the plane of insertion so that said connector contacts slide from said strips onto said correspondingly spaced conductive elements to electrically interconnect selected ones of said circuit signal points on adjacent ones of said circuit cards.
Claim 4
Dependent Claim
28 words
Apparatus in accordance with claim 2 wherein said conductor means comprises a plated-through hole interconnecting corresponding ones of said conductive elements on opposite sides of said circuit card.
