Abstract

Abstract A printed circuit card connector having upwardly extending card guides at its ends, each card guide having a heightwise end slot formed therein to receive the side edge of an inserted circuit card. Retention of the printed circuit card in the connector is enhanced by a pair of spaced, heightwise extending, resilient fingers which are supported within each end slot and which are adapted to receive and grip the circuit card therebetween. Each pair of fingers engages opposite faces of the inserted circuit card at a level which is above the socket and the fingers are of unequal length to retard vibration or common resonance. The fingers also may be employed as electrical contacts or terminals.

Dependent Claim 140 words
A connector as defined in claim 1 wherein each said dampening means comprises a pair of heightwise extending fingers disposed within each edge-receiving slot and spaced apart laterally of said socket for receiving a printed circuit card therebetween, each finger being bowed at a point intermediate its ends to define an apex which protrudes into said end slot and which constitutes said protruding portion of said dampening means adapted to engage said inserted circuit card, and further comprising means securing the lower end of each said finger to said insulative body for mounting said resilient dampening means at each end of said insulative body and disposing at least a portion of said dampening means in engagement with the face of said inserted circuit card adjacent its side edge and at a level that is above said lower marginal edge thereof.
Claim 6
Dependent Claim 22 words
A connector as defined in claim 4 wherein said apexes of said fingers of each dampening means are disposed at different levels.
Claim 7
Dependent Claim 18 words
A connector as defined in claim 4 wherein said fingers of each dampening means are of unequal length.
Claim 8
Dependent Claim 22 words
A connector as defined in claim 6 wherein said apexes of each dampening means are spaced heightwise with respect to each other.
Claim 9
Dependent Claim 176 words
In a circuit card connector having an insulative body in which is formed a socket adapted to receive the lower marginal edge of a circuit card, an improved arrangement for supporting a side edge of said circuit card comprising, in combination a card guide formed integrally with said insulative body at an end of said socket, said card guide extending outwardly beyond said insulative body and having a heightwise extending end slot formed therein to receive a side edge of said inserted circuit card, resilient dampening means comprising a pair of heightwise extending fingers of unequal length disposed within said end slot and spaced apart laterally of said socket for receiving a printed circuit card therebetween, and means securing the lower end of each said finger to said insulative body, and means mounting said dampening fingers on said insulative body at Each end thereof and disposing at least a portion of said fingers in engagement with said inserted circuit card adjacent its side edge and at a level that is above said lower marginal edge thereof.
Claim 10
Dependent Claim 176 words
In a circuit card connector having an insulative body in which is formed a socket adapted to receive the lower marginal edge of a circuit card, an improved arrangement for supporting a side edge of said circuit card comprising, in combination a card guide formed integrally with said insulative body at an end of said socket, said card guide extending outwardly beyond said insulative body and having a heightwise extending end slot formed therein to receive a side edge of said inserted circuit card, resilient dampening means comprising a pair of heightwise extending fingers of unequal length disposed within said end slot and spaced apart laterally of said socket for receiving a printed circuit card therebetween, and means securing the lower end of each said finger to said insulative body, and means mounting said dampening fingers on said insulative body at Each end thereof and disposing at least a portion of said fingers in engagement with said inserted circuit card adjacent its side edge and at a level that is above said lower marginal edge thereof.
