Smart card reader for elevated placement relative to a printed circuit board
First Claim
1. A connector for establishing electrical connection between at least one contact pad of an integrated circuit card and conductive elements of a printed circuit board, comprising:
- a substantially planar connector housing supportable on said printed circuit board, said housing having a lid and a base wherein each of said lid and said base further includes an upper surface and a lower surface defining a thickness therebetween and wherein said lid and said base define a card insertion slot therebetween for insertably accommodating said integrated circuit card therein;
a plurality of electrical contacts supported by said lid wherein each contact includes an interior contact extent having a freely deflectable spring-like portion defined thereat, said interior contact extent provided for electrical engagement with said contact pad of said integrated circuit card, and an exterior contact extent for termination to said printed circuit board; and
at least one normally extending offset members protruding from said base lower surface for elevating said connector above said printed circuit board so as to define a predetermined height therebetween;
wherein said lid includes a pair of longitudinally extending guide arms and said base includes a corresponding pair of longitudinal guide limbs extending from a central guide member such that said guide arms and said guide limbs together define card insertion rails along which said integrated circuit card is guided until insertion of said card into said slot.

Abstract
The present invention provides an electrical connector for connecting a contact pad of an IC card to a printed circuit board. In particular, a smart card connector is provided which elevates the connector above the PCB for placement of additional components therebeneath. The connector includes a housing having a top component and a bottom component affixed thereto wherein the top and bottom components together define a card insertion ingress at a front portion of the connector. The ingress is sized and shaped to accommodate linear sliding insertion of a smart card therein along a card insertion plane defined between the top and bottom portions. The top portion of the connector supports a plurality of electrical contacts therein wherein each contact includes an inner extent having a spring-like undulation at a freely deflectable extent positioned in the card insertion plane. Upon card insertion, a contact pad on the card engages the freely deflectable extent such that the undulation moves upward into a corresponding indentation defined along a bottom surface of the top portion of he connector. Upon retraction of the card, the undulation resiliently returns to its original position in the card insertion plane. Each contact further includes an outer extent that protrudes normally from the top portion of the connector for termination to the PCB. The contacts are desirably distributed in even and aligned rows that enable placement of all contacts in the top portion of the connector.
