Abstract
A contact frame for an IC card reader including contact elements for making connections with the IC card, the contact frame further including two electric contact blades (26, 28) carried by said frame and constituting an end-of-stroke contact (5), with one of said blades, a "fixed" blade (28), being coupled to the frame in such a manner that its stationary position relative to the frame is defined, while the other blade, a moving blade (26), is urged by a resilient force in a direction opposite to the direction in which a card is inserted into the reader, and is disposed in such a manner that a card being inserted comes into abutment thereagainst and imparts actuating motion thereto against its resilient force.
Claims6
A contact frame for an IC card reader comprising a slot for receiving an IC card, guide means for guiding the IC card through an end-of-stroke position up to a fully inserted position, contact elements carried by a molded frame of said contact frame and providing electrical connection to conducting pads on the main surface of the IC card, and an end-of-stroke contact comprising:
- a resilient "fixed" contact blade and a resilient moving contact blade, means for fixedly coupling one end of said "fixed" blade and one end of said moving blade to said molded frame of the contact frame, means causing the other end of the "fixed" blade to rest on a part of the contact frame due to its resilient force, and thus to be arrested in a well defined stationary position, the other end of said moving blade being positioned in the path of the inserted IC card such that the IC card comes into abutment against the other end of the moving blade and pushes said moving blade against its own resilient force, thereby operating the end-of-stroke contact precisely from the point said moving blade and said "fixed" blade just contacts each other, which point is defined by said part of said molded frame upon which the other end of said "fixed" blade comes to rest.
