Smart card connector with fraud protection
View Patent ↗A smart card connector with signal blade contacts having signal tails ( 34 a ) lying at the rear end of the connector frame, and with the connector being provided with a shield structure ( 110 ) that prevents a person from fraudulently contacting the signal tails during use of the connector. The shield structure includes a grounded conductive shield ( 40 ) having a rear portion that lies rearward of the signal tails. The conductive shield is mounted on an insulative barrier ( 60 ) that has a front portion ( 112 ) lying over the signal tails during use of the connector. The insulative barrier is pivotally mounted on the frame, between an open position wherein the shield structure leaves a region above the signal tails exposed during soldering, and a protect position wherein the shield structure blocks a region above and rearward of the signal tails.
1. A smart card connector for receiving a fully installed smart card, said connector having an insulative frame with a frame face that lies facewise adjacent to said fully installed smart card, and said connector having a plurality of contacts with parts that project vertically beyond said frame face for engaging contact pads of the smart card, wherein the connector is mounted on a circuit board that has a plurality of signal traces and at least one ground trace, and wherein a first of said contacts is a signal contact that has a rear end forming a signal tail that lies exposed at a rear end of said frame and that is connected to one of said signal traces, including:
a shield structure mounted on said connector, said shield structure including a metal shield that has a rearward portion that lies rearward of said tail to block easy access to said tail, and with said metal shield connected to said ground trace on said circuit board, whereby to help block unauthorized projection of a conductor device from the rear of said connector against said tail and to ground such a conductor device; wherein
said frame face of said insulative frame lies in a horizontal plane and said insulative frame has a rear end;
said signal contact has a rear portion that lies under said insulative frame and said signal contact has a rear part that extends rearward of an adjacent portion of said insulative frame and that merges with said tail; and including
an insulative barrier with a rear portion that lies above said metal shield;
said insulative barrier has a forward barrier part that lies in a protecting position wherein said forward barrier part extends over said rear part of said signal contact rear portion and over said tail, said forward barrier part has an upper face that lies no higher than said insulative frame rear end, and said forward barrier part has a front end that abuts said rear end of said insulative frame.
2. A smart card connector for receiving a fully installed smart card, said connector having an insulative frame that forms a slot with an open rear end for receiving said smart card by forward insertion of the smart card into the slot, said frame having a frame face that lies facewise adjacent to said fully installed smart card, and said connector having a plurality of contacts with parts that project vertically beyond said frame face for engaging contact pads of the smart card, wherein the connector is mounted on a circuit board that has a plurality of signal traces and at least one ground trace, and wherein a first of said contacts is a signal contact that has a rear end forming a signal tail that lies exposed at a rear end of said frame and that is connected to one of said signal traces, including:
a shield structure mounted on said connector, said shield structure including a metal shield that has a rearward portion that lies rearward of said tail to block easy access to said tail, and with said metal shield connected to said ground trace on said circuit board, whereby to help block unauthorized projection of a conductor device from the rear of said connector against said tail and to ground such a conductor device;
said shield structure is moveable from a raised position wherein it blocks said slot and leaves open a space above said signal tail, to a protecting position wherein said shield structure does not block said slot but blocks said space above said signal tail.
3. A smart card connector for receiving a smart card, said connector having an insulative frame with a card-adjacent frame face that lies facewise adjacent to a smart card that has been fully installed, and said connector having a plurality of contacts that project vertically beyond said frame face for engaging contact pads of said smart card that has been fully installed, wherein the connector is constructed for mounting on a circuit board that has at least one signal trace and at least one ground trace, and wherein at least one of said contacts is a signal contact that has a rear end forming a tail that lies at a rear end of said frame and that is designed to connect to said signal trace, including:
a shield structure for shielding said signal tail, said shield structure being moveably mounted on said frame to move between an initial position wherein the rear end of said signal tail is exposed through a primarily vertical space subtending an arc of more than 10° upward from a bottom of said tail and a protected position wherein said shield structure has portions lying above and rearward of said signal tail and blocks access to said signal tail from above and through said space and from the rear of said connector;
said shield structure including an insulative barrier and a sheet metal shield mounted on said insulative barrier, said insulative barrier being mounted on said frame;
said insulative barrier having a forward barrier part that extends forward of said sheet metal shield and over said signal tail.
