Abstract
Abstract A controlled insertion force receptacle for flat circuit bearing elements such as printed circuit boards. A first block of an insulating material having a slot in it which is adapted to receive the element. At least one contact finger is mounted in the first block and is positioned so as to make physical and electrical contact with a contact point on the element when the element is in the slot. A second block of an insulating material is mounted on the first block in a manner so as to be free to move relative to the first block in a direction perpendicular to the walls of the slot. The second block engages the contact fingers and causes the fingers to move to controlled positions in or out of the slot as the second block is moved relative to the first block. A member such as a camshaft is provided for moving the second block relative to the first block.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A receptacle for a flat circuit bearing element having contact points along at least one edge thereof comprising: a first block of an insulating material having a slot therein which is adapted to receive the edge of said element having said contact points; at least one contact means mounted in said first block and positioned to be capable of makIng physical and electrical contact with a contact point of said element when said element is in said slot; a second block of an insulating material mounted on said first block and movable relative to said first block in a direction perpendicular to the walls of said slot, said second block including means engageable with said contact means at a point above the point at which said contact means contacts said element, so as to cause said contact means to move to controlled positions relative to said slot as said second block is moved relative to said first block; and means for moving said second block relative to said first block.
Claim 2
Dependent Claim
170 words
A receptacle for a flat circuit bearing element having contact points along at least one edge thereof comprising: a first block of an insulating material having a slot therein which is adapted to receive the edge of said element having said contact points; at least one contact means mounted in said first block and positioned to be capable of makIng physical and electrical contact with a contact point of said element when said element is in said slot; a second block of an insulating material mounted on said first block and movable relative to said first block in a direction perpendicular to the walls of said slot, said second block including means engageable with said contact means at a point above the point at which said contact means contacts said element, so as to cause said contact means to move to controlled positions relative to said slot as said second block is moved relative to said first block; and means for moving said second block relative to said first block.
Claim 3
Dependent Claim
63 words
A receptacle of the type described in claim 1 wherein said contact means is normally biased to a position in said slot in which it makes physical and electrical contact with a contact point of said element; and wherein said moving means is operative to move said second block to a position in which it substantially removes said contact means from said slot.
Claim 4
Dependent Claim
28 words
A receptacle of the type described in claim 1 wherein said second block has a pocket which is adapted to engage the upper tip of said contact means.
Claim 5
Dependent Claim
71 words
A receptacle of the type described in claim 1 wherein the controlled positions to which said contact means may be moved include a first position in which said contact means is in said slot and adapted to make contact with a contact point of said element, and a second position in which said contact means is substantially out of said slot and not adapted to make contact with said contact point.
Claim 6
Dependent Claim
24 words
A receptacle of the type described in claim 1 wherein said moving means includes a camshaft which passes between said first and second blocks.
Claim 7
Dependent Claim
59 words
A receptacle of the type described in claim 5 wherein there are a plurality of said contact means, each adapted to make physical and electrical contact with a different contact point of said element; and wherein said second block and said moving means including said single camshaft are operative to control the position of all of said contact means.
Claim 8
Dependent Claim
88 words
A receptacle of the type described in claim 5 wherein said second body is movable, by rotation of said camshaft through a predetermined angle, from a first position in which said contact means is free to enter said slot and is adapted to make contact with a contact point of said element, to a second position in which said contact means is moved by said second body substantially out of said slot to an extent such that it is not capable of making contact with said contact point.
Claim 9
Dependent Claim
15 words
A receptacle of the type described in claim 7 wherein said predetermined angle is 90*.
Claim 10
Dependent Claim
30 words
A receptacle of the type described in claim 7 including means operative when said block is in said first position for preventing an element from being inserted in said slot.
Claim 11
Dependent Claim
43 words
A receptacle of the type described in claim 9 wherein said element insertion prevention means is adapted to rotate from a blocking to a nonblocking position as said camshaft is rotated to move said second block from said first to said second position.
