Abstract
Abstract An IC card connecting mechanism connects an IC card having a terminal array with a connector for connecting the IC card to external equipment. The IC card connecting mechanism includes a frame of the IC card, having a peripheral rim provided with recesses at opposite ends of the front portion thereof, a terminal protecting member of the IC card, having a terminal protecting part for protectively covering the terminal array, and legs extending from the opposite longitudinal sides of the terminal protecting part and held at respective free ends thereof on the frame of the IC card. A body of the connector has guide legs for guiding the IC card upon inserting the IC card in the connector. Lifting devices provided in the body of the connector enter the recesses of the frame to lift up the terminal protecting part of the terminal protecting member when the IC card is inserted in the connector. Thus, the terminal protecting part of the terminal protecting member is lifted up automatically to expose the terminal array for electrical connection with conductors of the connector when the IC card is inserted in the connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
239 words
An IC card connecting mechanism for connecting an IC card having a terminal array in a front end thereof, and a connector for connecting the IC card to external equipment and having contacts to be electrically connected to respective connection terminals of the terminal array, said IC card connecting mechanism comprising: a frame of the IC card, said frame having a peripheral rim provided with recesses at opposite ends of a front portion thereof; a terminal protecting means of the IC card, positioned in said frame at a fixed position to cover the terminal erray protectively, to cover said recesses of said frame and to be lifted up away from the terminal array upon connecting the IC card to the connector; a top cover of the IC card fixedly placed on top of said frame to hold said terminal protecting means in place on said frame; a body of the connector having guide legs extending from respective opposite longitudinal sides thereof, said guide legs having guide groooves formed in respective inner surfaces thereof to receive respective front portions of opposite longitudinal side edges of the IC card to guide the IC card upon connecting the IC card to the connector; and lifting means provided in the body of the connector for entering said recesses of said frame to lift up said terminal protecting means so that the terminal array is exposed for connection with the contacts of the connector.
Claim 2
Dependent Claim
239 words
An IC card connecting mechanism for connecting an IC card having a terminal array in a front end thereof, and a connector for connecting the IC card to external equipment and having contacts to be electrically connected to respective connection terminals of the terminal array, said IC card connecting mechanism comprising: a frame of the IC card, said frame having a peripheral rim provided with recesses at opposite ends of a front portion thereof; a terminal protecting means of the IC card, positioned in said frame at a fixed position to cover the terminal erray protectively, to cover said recesses of said frame and to be lifted up away from the terminal array upon connecting the IC card to the connector; a top cover of the IC card fixedly placed on top of said frame to hold said terminal protecting means in place on said frame; a body of the connector having guide legs extending from respective opposite longitudinal sides thereof, said guide legs having guide groooves formed in respective inner surfaces thereof to receive respective front portions of opposite longitudinal side edges of the IC card to guide the IC card upon connecting the IC card to the connector; and lifting means provided in the body of the connector for entering said recesses of said frame to lift up said terminal protecting means so that the terminal array is exposed for connection with the contacts of the connector.
Claim 3
Dependent Claim
21 words
An IC card connecting mechanism according to claim 1, wherein said top cover is formed integrally with said terminal protecting means.
Claim 4
Dependent Claim
110 words
An IC card connecting mechanism according to claim 1, wherein said lifting means comprise L-shaped levers, each said lever having a vertical arm and a horizontal arm and pivotally supported by a pivot pin inside a respective guide leg of said body of the connector, so that said horizontal arms enter respective of said recesses of said rim of said frame and said vertical arms are pushed by the front edge of the IC card, and thereby said levers are turned on said pivot pin such that said horizontal arms lift upwardly said terminal protecting part of said terminal protecting means when the IC card is inserted in the connector.
Claim 5
Dependent Claim
275 words
An IC card connecting mechanism according to claim 1, wherein: said terminal protecting means comprises a plate-shaped terminal protecting member formed of an elastic material, said member having a terminal protecting part formed of a size capable of covering the terminal array and to be fitted upwardly away therefrom, and legs projecting rearwardly from opposite longitudinal sides of said terminal protecting part and provided with through holes in respective free ends thereof; opposite corners of a front end of said terminal protecting part are bent upwardly to form guide surfaces to engage said lifting means of the connector when the IC card is connected to the connector; said frame is provided with posts inwardly of opposite longitudinal portions of said rim at positions corresponding to respective of said through holes of said legs of said terminal protecting member, said posts being received in said respective through holes to locate said terminal protecting member in said frame so that the terminal array is covered with said terminal protecting part of said terminal protecting member; said top cover holds said terminal protecting member in place at free ends thereof provided with said through holes so that said legs can be fixed when said terminal protecting part is lifted upwardly; and said lifting means comprise lifting fingers having respective sloping guide surfaces and provided at respective roots of the legs of said body of the connector so as to enter said recesses of said frame and engage respective of said guide surfaces of said terminal protecting member, to lift upwardly said terminal protecting part of said terminal protecting member when the IC plate is inserted in the connector.
Claim 6
Dependent Claim
20 words
An IC card connecting mechanism according to claim 4, wherein said lifting fingers are formed of an electrically conductive material.
