Abstract
Abstract Printed circuit apparatus has the circuit board structure which carries the edge contacts constructed with two sheet members in register with each other and having a total thickness less than standard, and with a wedge member between the sheet members and movable to separate them, after plugging them into an edgereceiving receptacle, to the thickness standard for the receptacle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
148 words
Printed circuit apparatus for facile removable and replaceable connection with an electrical receptacle device, said apparatus having printed circuit board means having first and second sides and carrying contacts on at least a first side thereof along a first board edge which is opposite a second board edge, and having the improvement comprising A. first and second sheet-like members in register with each other and forming respectively said first and second sides of said printed circuit board means along at least said first edge thereof, B. means holding said first and second sheet members in register with each other, and C. wedge means interposed between said sheet members for selectively separating them at said first edge, said wedge means being movable between a first position adjacent said first board edge and a second position removed from said first board edge in the direction toward said second board edge.
Claim 2
Dependent Claim
148 words
Printed circuit apparatus for facile removable and replaceable connection with an electrical receptacle device, said apparatus having printed circuit board means having first and second sides and carrying contacts on at least a first side thereof along a first board edge which is opposite a second board edge, and having the improvement comprising A. first and second sheet-like members in register with each other and forming respectively said first and second sides of said printed circuit board means along at least said first edge thereof, B. means holding said first and second sheet members in register with each other, and C. wedge means interposed between said sheet members for selectively separating them at said first edge, said wedge means being movable between a first position adjacent said first board edge and a second position removed from said first board edge in the direction toward said second board edge.
Claim 3
Dependent Claim
69 words
Apparatus according to claim 1 wherein A. said first and second sheet members extend between said first and second board edges, B. at least one sheet member carries edge contacts along said second board edge, and C. a spacer is interposed between said sheet members along said second board edge, said spacer extending between said sheets for only part of the distance between said first and second board edges.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 1 further comprising yieldable means urging said sheet members together at said first board edge.
Claim 5
Dependent Claim
33 words
Apparatus according to claim 1 wherein said wedge means includes wedge transport means protruding from said printed circuit board means and for moving said wedge means between said first and second positions thereof.
Claim 6
Dependent Claim
70 words
Printed circuit apparatus according to claim 1 for connection with a receptacle device having a board-edge receiving socket with a first width, and further characterized in that A. said first and second sheet members have a combined second thickness adjacent said first edge thereof less than said first width, and B. said wedge means has a thickness substantially equal to the difference between said first width and said second thickness.
Claim 7
Dependent Claim
136 words
A circuit board for repeated ready removal and insertion at a first edge spaced opposite a second edge into an edge-engaging electrical receptacle device, said board comprising A. first and second sheet members in register with each other and providing said circuit board with a first thickness at least at said first edge thereof, B. shim-like wedge means sandwiched between said sheet members and movable between a first position adjacent said first board edge to provide with said sheet members a second thickness of said board at least at said first edge thereof, and a second position removed from said first board edge in the direction toward said second board edge, and C. wedge-moving means extending outward beyond said circuit board and coupled to said wedge means for moving it between said first and second positions.
Claim 8
Dependent Claim
136 words
A circuit board for repeated ready removal and insertion at a first edge spaced opposite a second edge into an edge-engaging electrical receptacle device, said board comprising A. first and second sheet members in register with each other and providing said circuit board with a first thickness at least at said first edge thereof, B. shim-like wedge means sandwiched between said sheet members and movable between a first position adjacent said first board edge to provide with said sheet members a second thickness of said board at least at said first edge thereof, and a second position removed from said first board edge in the direction toward said second board edge, and C. wedge-moving means extending outward beyond said circuit board and coupled to said wedge means for moving it between said first and second positions.
Claim 9
Dependent Claim
26 words
A circuit board according to claim 6 further comprising means urging said first and second sheet members together with resilient force adjacent said first board edge.
Claim 10
Dependent Claim
33 words
A circuit board according to claim 7 in which said resiliently-urging means comprises a permanent magnet element on one sheet member and a magnetic element in register therewith on the other sheet member.
Claim 11
Dependent Claim
40 words
A circuit board according to claim 7 in which said resiliently-urging means comprises first and second clamping elements mounted with said board on opposite sides of said sheet members and resiliently urged toward each other adjacent said first board edge.
Claim 12
Independent Claim
99 words
A method for connecting an electrical circuit board with a receptacle device mountingly receiving a circuit-board edge, said method comprising the successive steps of A. forming a first connection edge of said circuit board with a paIr of delaminated sheet members having a combined first thickness sufficiently small to be substantially freely received in said receptacle device, B. inserting said first connection edge of said circuit board into said receptacle device, and C. separating said sheet members at said first connection edge to second thickness greater than said first thickness and sufficiently large to engage said receptacle device securely.
Claim 13
Independent Claim
99 words
A method for connecting an electrical circuit board with a receptacle device mountingly receiving a circuit-board edge, said method comprising the successive steps of A. forming a first connection edge of said circuit board with a paIr of delaminated sheet members having a combined first thickness sufficiently small to be substantially freely received in said receptacle device, B. inserting said first connection edge of said circuit board into said receptacle device, and C. separating said sheet members at said first connection edge to second thickness greater than said first thickness and sufficiently large to engage said receptacle device securely.
Claim 14
Dependent Claim
25 words
A method according to claim 10 comprising the further step of urging said sheet members together adjacent said first connection edge during said inserting step.
