Abstract
Abstract A receptacle which applies a small controlled force, for example zero force, to flat circuit bearing elements during element insertion and withdrawal. The receptacle includes a frame having an element receiving slot. A slide is positioned in the frame under the slot and is raised by rotating a cam shaft. The slide has projecting fingers which engage the ends of contact fingers to move a point midway along each contact finger further into the element receiving slot thus causing the contact finger to apply increased pressure to an element position in the slot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A receptacle for a flat circuit bearing element having contact points along at least one edge thereof comprising: a frame assembly having a slot therein which is adapted to receive the edge of said element having said contact points; at least one contact mounted in said frame, said contact being angled toward said slot to a first point midway along its length and away from said slot for the remainder of its length, said first point being normally positioned relative to said slot so as to be adapted to apply a controlled pressure to an element position in the slot; a slide positioned in said frame and normally biased to a first position, a cam shaft positioned between said slide and frame assembly; and means for moving said slide to a second position in which it is applying pressure to a second point near the end of said contact to move said contact toward said slot, whereby the pressure applied by said first point to said element is increased.
Claim 2
Dependent Claim
169 words
A receptacle for a flat circuit bearing element having contact points along at least one edge thereof comprising: a frame assembly having a slot therein which is adapted to receive the edge of said element having said contact points; at least one contact mounted in said frame, said contact being angled toward said slot to a first point midway along its length and away from said slot for the remainder of its length, said first point being normally positioned relative to said slot so as to be adapted to apply a controlled pressure to an element position in the slot; a slide positioned in said frame and normally biased to a first position, a cam shaft positioned between said slide and frame assembly; and means for moving said slide to a second position in which it is applying pressure to a second point near the end of said contact to move said contact toward said slot, whereby the pressure applied by said first point to said element is increased.
Claim 3
Dependent Claim
28 words
A receptacle of the type described in 1 wherein said cam shaft is of a metallic material and said slide and frame assembly are of an insulating material.
Claim 4
Dependent Claim
28 words
A receptacle of the type described in 1 wherein said cam shaft is of a metallic material and said slide and frame assembly are of an insulating material.
Claim 5
Dependent Claim
190 words
A receptacle for a flat circuit bearing element Having contact points along a pair of opposite edges thereof comprising: a frame assembly having a slot therein which is adapted to receive said edges of said element having said contact points; at least one pair of oppositely positioned contacts mounted in said frame, each of said contacts being angled toward said slot to a first point midway along its length and away from said slot for the remainder of its length, said first point being normally positioned relative to said slot so as to be adapted to apply a controlled pressure to said element in said slot a slide positioned in said frame assembly and normally biased to a first position, said slide including a finger for each contact; and means between said slide and said frame assembly for moving said slide including said fingers to a second position in which each of said fingers is applying pressure to a second point near the end of each of said contacts to move said each contact toward said slot, whereby the pressure applied by said first point to said element is increased.
Claim 6
Dependent Claim
190 words
A receptacle for a flat circuit bearing element Having contact points along a pair of opposite edges thereof comprising: a frame assembly having a slot therein which is adapted to receive said edges of said element having said contact points; at least one pair of oppositely positioned contacts mounted in said frame, each of said contacts being angled toward said slot to a first point midway along its length and away from said slot for the remainder of its length, said first point being normally positioned relative to said slot so as to be adapted to apply a controlled pressure to said element in said slot a slide positioned in said frame assembly and normally biased to a first position, said slide including a finger for each contact; and means between said slide and said frame assembly for moving said slide including said fingers to a second position in which each of said fingers is applying pressure to a second point near the end of each of said contacts to move said each contact toward said slot, whereby the pressure applied by said first point to said element is increased.
Claim 7
Dependent Claim
27 words
A receptacle of the type described in claim 3 wherein said slide moving means is of metallic material and said frame assembly is of an insulating material.
Claim 8
Dependent Claim
20 words
A receptacle of the type described in claim 4 wherein said slide moving means is also disposed between said contacts.
Claim 9
Dependent Claim
18 words
A receptacle of the type described in claim 5 wherein said slide moving means is a cam shaft.
