Abstract
Abstract Printed circuit boards having perimeter edge connectors on either side of the boards are interconnected to each other by means of a removable connector comprised of top and bottom members to establish connections respectively to the top and bottom surfaces of said boards, the top member further having facilities to enable cable connections to be established to an external source which may be any form of an input/output instrumentality or another circuit board at some other location.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A circuit board connector for mechanically interconnecting circuit boards along their planar peripheral surface edges and simultaneously establishing interboard electrical connections and external connections by way of electrical conductive pads disposed on either side and along said peripheral edges of said boards comprising: a first longitudinal member disposed to mechanically engage the planar peripheral surface edges on one side of said boards, said member having a plurality of spring blade members each adapted to engage a pair of opposed tabs on one side of adjacently disposed boards to establish electrical connections therebetween; a second longitudinal member disposed to mechanically engage correspondingly peripheral planar surface edges on the opposite side of said boards, said second member having an internal ground plane, and a plurality of electrically conductive signal pins electrically isolated from one another and passing through said plane but electrically isolated therefrom, each pin adapted to engage an individual tab on said opposite side of said boards, and mechanical means for securing said members to said boarDs to mechanically interconnect said boards and to provide the electrical connections therebetween and between said boards and said external connections.
Claim 2
Dependent Claim
187 words
A circuit board connector for mechanically interconnecting circuit boards along their planar peripheral surface edges and simultaneously establishing interboard electrical connections and external connections by way of electrical conductive pads disposed on either side and along said peripheral edges of said boards comprising: a first longitudinal member disposed to mechanically engage the planar peripheral surface edges on one side of said boards, said member having a plurality of spring blade members each adapted to engage a pair of opposed tabs on one side of adjacently disposed boards to establish electrical connections therebetween; a second longitudinal member disposed to mechanically engage correspondingly peripheral planar surface edges on the opposite side of said boards, said second member having an internal ground plane, and a plurality of electrically conductive signal pins electrically isolated from one another and passing through said plane but electrically isolated therefrom, each pin adapted to engage an individual tab on said opposite side of said boards, and mechanical means for securing said members to said boarDs to mechanically interconnect said boards and to provide the electrical connections therebetween and between said boards and said external connections.
Claim 3
Dependent Claim
22 words
The connector as in claim 1 in which ground pins are interposed between said signal pins and interconnected to said ground plane.
Claim 4
Dependent Claim
26 words
The connector as in claim 1 in which the surface of said second member is further provided with a printed circuit pattern interconnecting said signal pins.
Claim 5
Dependent Claim
36 words
The connector as in claim 1 in which said second member is further provided with a ground rail connected to desired ones of said ground pins and held in spaced relationship above said printed circuit pattern.
Claim 6
Dependent Claim
17 words
The connector as in claim 1 in which said ground rail is constituted of a single rail.
Claim 7
Dependent Claim
17 words
The connector as in claim 1 in which said ground rail is constituted of a double rail.
Claim 8
Dependent Claim
23 words
The connector as in claim 1 in which said second member has a generally shaped configuration adapted to receive an external cable connection.
