Abstract

A smart card reader 10 is disclosed having a base 12 which is profiled to have a card receiving area 20. Contacts 22,23 are disposed inside a contact receiving 32 of the base and are pivotable about a leg 40. Insertion of a smart card 60 causes the contacts 22,23 to pivot about the pivot point 42 in order to cause contact points 50 to engage contact pads of the smart card 60.

Claims

1. A smart card reader having a base being profiled to have a card receiving area, a contact receiving area in communication with the card receiving area, and a plurality of contacts disposed in the contact receiving area, each of the contacts having a leg passing through the base for electrical connection with a printed circuit board, each contact being characterized by:

an arm extending from the leg and being pivotable in relation to the leg, a contact point disposed on the arm at an end toward the mating face and an actuating section disposed on the arm at an end opposite the contact point.

2. The smart card reader as recited in claim 1 wherein the contact point is plated with at least one of the following metals selected from the class:

palladium, nickel, and gold.

3. The smart card reader as recited in claim 1 wherein the contact point further comprises a gold material deposited thereon by thermo-compression bonding.

4. The smart card reader as recited in claim 1 wherein the actuating section comprises a camming surface which is engageable by an edge of a smart card to urge the actuating section away from the smart card and the contact section toward the smart card.

5. The smart card reader as recited in claim 1 wherein the arm is positioned over the leg such that the actuating section lies on a first side of the leg and the contact section lies on a second side of the leg opposite the first side.

6. The smart card reader as recited in claim 1 wherein the arm extends from the leg in a cantilever fashion such that the arm has a free end.

7. The smart card reader as recited in claim 6 wherein the actuating section is generally C-shaped and is disposed at the free end of the arm such that a first end of the C-shaped actuating section extends from the arm and a second end has a camming surface facing the arm.

8. A smart card reader comprising:

a base being profiled to have a card receiving area and a contact receiving area,

a cover being mounted to the base over the card receiving area, and;

a plurality of contacts each having a leg which extends through the base in the contact receiving area, and an arm pivotably extending from the base, the arm consisting of a contact section and an actuating section,

whereby a card is slidably receivable into the card receiving area such that it will first engage the actuating sections causing the arms to pivot about the legs to effect an electrical connection between the contact sections and pads on a surface of the card.

9. The smart card reader as recited in claim 8 wherein the contact section is gold plated.

10. The smart card reader as recited in claim 8 wherein the contact section further comprises a gold material deposited thereon by thermo-compression bonding.

11. The smart card reader as recited in claim 8 wherein the arm is positioned over the leg such that the actuating section lies on a first side of the leg and the contact section lies on a second side of the leg opposite the first side.

12. The smart card reader as recited in claim 11 wherein the actuating section comprises a camming surface which is engageable by an edge of a smart card to urge the actuating section away from the smart card and the contact section toward the smart card.

13. The smart card reader as recited in claim 8 wherein the arm extends from the leg in a cantilever fashion such that the arm has a free end.

14. The smart card reader as recited in claim 13 wherein the actuating section is generally C-shaped and is disposed at the free end of the arm such that a first end of the C-shaped actuating section extends from the arm and a second end has a camming surface facing the arm.
