Abstract
Abstract This invention relates to printed circuit board electrical connector receptacles, and in one embodiment comprises a receptacle for receiving a modular circuit component member of the so-called "dual in-line" type wherein removal of such a component package is facilitated through operation of movable cam means integral with the receptacle, which means is positioned beneath the component member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
174 words
An electrical connector receptacle for effecting electrical interconnection with a circuit component which has a multiplicity of contact members that project a substantially the same direction from said circuit component, comprising at least one peripheral edge, an upper support surface to which said component is to be juxtaposed when said component is in normal use with said contact members electrically interconnected with corresponding members in said receptacle, a base having at least one upward facing inclined plane within said receptacle, which slopes downward in the direction of said receptacle, and a cam member juxtaposed to said inclined plane, and having an upper surface, the uppermost portions of which are configured correspondingly to the uppermost portions of said support surface so as cooperatively therewith to present a unified contact surface to a circuit component positioned thereon, and also having a downward facing inclined plane forming its lower surface substantially corresponding in slope to and shorter in length than the corresponding inclined plane in the base of the receptacle to which it is to be juxtaposed.
Claim 2
Dependent Claim
174 words
An electrical connector receptacle for effecting electrical interconnection with a circuit component which has a multiplicity of contact members that project a substantially the same direction from said circuit component, comprising at least one peripheral edge, an upper support surface to which said component is to be juxtaposed when said component is in normal use with said contact members electrically interconnected with corresponding members in said receptacle, a base having at least one upward facing inclined plane within said receptacle, which slopes downward in the direction of said receptacle, and a cam member juxtaposed to said inclined plane, and having an upper surface, the uppermost portions of which are configured correspondingly to the uppermost portions of said support surface so as cooperatively therewith to present a unified contact surface to a circuit component positioned thereon, and also having a downward facing inclined plane forming its lower surface substantially corresponding in slope to and shorter in length than the corresponding inclined plane in the base of the receptacle to which it is to be juxtaposed.
Claim 3
Dependent Claim
64 words
The device described in claim 1 wherein said cam member is longer than the distance from the innermost end thereof to the peripheral edge of said receptacle when said cam is positioned with its lower surface juxtaposed to said corresponding inclined plane with said uppermost portions of said upper surface positioned at the same height as are the corresponding portions of said support surface.
Claim 4
Dependent Claim
31 words
The device described in claim 1 including bias means for causing each of said cam members normally to be impelled toward the peripheral edge of said housing toward which it slopes.
Claim 5
Dependent Claim
18 words
The device described in claim 3 wherein said bias means is integral with each of said cam members.
Claim 6
Dependent Claim
26 words
The device described in claim 1 comprising two inclined planes, one of each of which slopes downward toward a different one of sidewalls of said receptacle.
Claim 7
Dependent Claim
26 words
The device described in claim 2 comprising two inclined planes, one of each of which slopes downward toward a different one of sidewalls of said receptacle.
Claim 8
Dependent Claim
27 words
The device described in claim 3 comprising two inclined planes, one of each of which slopes downward toward a different one of said sidewalls of said receptacle.
Claim 9
Dependent Claim
16 words
The device described in claim 4 wherein said cam members are integrally connected to each other.
Claim 10
Dependent Claim
16 words
The device described in claim 5 wherein said cam members are integrally connected to each other.
Claim 11
Dependent Claim
16 words
The device described in claim 6 wherein said cam members are integrally connected to each other.
Claim 12
Dependent Claim
24 words
The device described in claim 1 comprising two inclined planes, one of each of which slopes downward toward one of sidewalls of said receptacle.
Claim 13
Dependent Claim
24 words
The device described in claim 2 comprising two inclined planes, one of each of which slopes downward toward one of sidewalls of said receptacle.
Claim 14
Dependent Claim
25 words
The device described in claim 3 comprising two inclined planes, one of each of which slopes downward toward one of said sidewalls of said receptacle.
Claim 15
Dependent Claim
16 words
The device described in claim 10 wherein said cam members are integrally connected to each other.
Claim 16
Dependent Claim
16 words
The device described in claim 11 wherein said cam members are integrally connected to each other.
Claim 17
Dependent Claim
16 words
The device described in claim 12 wherein said cam members are integrally connected to each other.
