Abstract
Abstract A circuit board edge connector that utilizes alternating conductive (5) and non-conductive (6) segments of elastomeric strips (4) to provide discrete electrical conductivity between pairs of boards (illustratively 40 and 60). The disclosed structure maintains surface contact between boards (1) and associated elastomeric strips (4), and between associated elastomeric strips (4).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
A structure for electrically interconnecting a first and a second set of circuit boards, said structure comprising: first and second rectangular, flat holding members each having a plurality of parallel slots therein, and elastomeric strips of alternating electrically conductive and non-conductive segments segments placed respectively in each said slot, wherein a first edge of each said board of said first set is placed in surface contact along the length of an associated said strip on a first side of said first holding member, a first edge on each said board of said second set is placed in surface contact along the length of an associated strip on a first side of said second holding member, and wherein a second side of said second holding member is placed flush and fixedly maintained in surface contact with a second side of said first holding member, an edge of each said board in said first set having an electrically conductive path to an edge of each said board in said second set via the associated two said strips.
Claim 2
Dependent Claim
175 words
A structure for electrically interconnecting a first and a second set of circuit boards, said structure comprising: first and second rectangular, flat holding members each having a plurality of parallel slots therein, and elastomeric strips of alternating electrically conductive and non-conductive segments segments placed respectively in each said slot, wherein a first edge of each said board of said first set is placed in surface contact along the length of an associated said strip on a first side of said first holding member, a first edge on each said board of said second set is placed in surface contact along the length of an associated strip on a first side of said second holding member, and wherein a second side of said second holding member is placed flush and fixedly maintained in surface contact with a second side of said first holding member, an edge of each said board in said first set having an electrically conductive path to an edge of each said board in said second set via the associated two said strips.
Claim 3
Dependent Claim
53 words
The structure of claim 1 wherein said slots traverse less than the length of said members and the aperture of said slots is widest at the point where said boards are inserted and narrowest at the point where said strips are situated, such that said member is in edge contact with said boards.
Claim 4
Dependent Claim
98 words
The structure of claim 1 wherein said structure further comprises a midplane board situated between said first and said second holding members and having conductive paths along its surfaces adjacent said first and second holding members, such that an electrically conductive path can be established between a designated point on said first edge of each said circuit board of said first set and a designated point on said first edge of the same said circuit board or any other of said circuit boards via the associated ones of said strips and said conductive paths of said midplane board.
