Abstract
Abstract Interconnection between a large planar electronic printed circuit board and a plurality of relatively smaller electronic printed circuit cards is accomplished by connecting the planar board to an array board by means of elongated interposer connectors. The array board contains a plurality of positions which accommodate the plugging of electronic printed circuit cards and cables. A mechanical ejection system allows the planar board to be removed from the system without disturbing the cards, cables or the interposer connection to the array board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
In an electronic system having a plurality of printed circuit cards and a planar printed circuit board with a plurality of transversely projecting contact means, means for connecting said cards to said planar printed circuit board comprising: elongated interposer means having first connector means at one end thereof for mating with contact means on said planar printed circuit board and a polarized second connector means at the opposite end thereof, an array board having contact means matched to said polarized connector means and connected to further contact means on said array board, said further contact means adapted to receive a printed circuit card connector, and means for disengaging said planar board from said interposer means including a pair of cofunctioning counter-rotating levers pivotally mounted on said array board and adapted to engage the abutting surface of said planar board to remove the planar board contact means from said connector means.
Claim 2
Dependent Claim
150 words
In an electronic system having a plurality of printed circuit cards and a planar printed circuit board with a plurality of transversely projecting contact means, means for connecting said cards to said planar printed circuit board comprising: elongated interposer means having first connector means at one end thereof for mating with contact means on said planar printed circuit board and a polarized second connector means at the opposite end thereof, an array board having contact means matched to said polarized connector means and connected to further contact means on said array board, said further contact means adapted to receive a printed circuit card connector, and means for disengaging said planar board from said interposer means including a pair of cofunctioning counter-rotating levers pivotally mounted on said array board and adapted to engage the abutting surface of said planar board to remove the planar board contact means from said connector means.
Claim 3
Dependent Claim
53 words
A system according to claim 1 wherein said means for disengaging said planar board includes two pair of cofunctioning counter-rotating levers pivotally mounted at opposite ends of said array board and adapted to engage the abutting surface of said planar board to remove the planar board contact means from said first connector means.
Claim 4
Dependent Claim
12 words
A system according to claim 2 wherein said levers are screw actuated.
Claim 5
Dependent Claim
158 words
An electronic system having a plurality of printed circuit cards comprising a planar board with a plurality of transversely projecting contact means, means for connecting said cards to said planar board, elongated interposer means having first connector means at one end thereof for mating with the contact means on said planar board and a polarized second connector means at the opposite end thereof, an array board having contact means matched to said polarized second connector means and connected to further contact means on said array board, said further contact means adapted to receive a printed circuit card connector, and means for disengaging said planar board from said interposer means including a pair of cofunctioning counter-rotating levers pivotally mounted on one of said array board and said planar board and adapted to engage the abutting surface of the other of said array board and said planar board to interrupt electrical contact between said array board and said planar board.
Claim 6
Dependent Claim
158 words
An electronic system having a plurality of printed circuit cards comprising a planar board with a plurality of transversely projecting contact means, means for connecting said cards to said planar board, elongated interposer means having first connector means at one end thereof for mating with the contact means on said planar board and a polarized second connector means at the opposite end thereof, an array board having contact means matched to said polarized second connector means and connected to further contact means on said array board, said further contact means adapted to receive a printed circuit card connector, and means for disengaging said planar board from said interposer means including a pair of cofunctioning counter-rotating levers pivotally mounted on one of said array board and said planar board and adapted to engage the abutting surface of the other of said array board and said planar board to interrupt electrical contact between said array board and said planar board.
Claim 7
Dependent Claim
59 words
A system according to claim 4 wherein said means for disengaging said planar board from said interposer means includes two pair of cofunctioning counter-rotating levers pivotally mounted at opposite ends of said one of said array board and said planar board and adapted to engage the abutting surface of the other of said array board and said planar board.
Claim 8
Dependent Claim
12 words
A system according to claim 5 wherein said levers are screw actuated.
