IC card connector with click projection for insert control

Claim 1

An IC card connector, comprising: a housing having a card slot into which said IC card is inserted, a plurality of terminals secured cantilevered in said housing and having contact portions protruding into said card slot, a detection switch mounted in the back of said card slot for detecting whether or not IC card insertion into said card slot has been completed, and an elastic piece extended cantilevered in the direction of IC card insertion and formed as a click projection with the free end thereof protruding into said card slot; said click projection constructed such that said elastic piece has an abutting surface which is approximately perpendicular to the inserting direction and to which the front edge of said IC card is abutted, and when the front edge of said IC card is abutted against said abutting surface during the inserting operation of said IC card, the click projection is flexed in a direction crossing at a right angle of the inserting direction and when the amount of flexing state reaches a predetermined amount, the front edge of said IC card rides over said click proiection: said IC card connector being constituted constructed such that when said click projection is driven by the front edge of said IC card in the direction of insertion of said IC card to push to deflect said elastic piece, a plurality of contacts arranged on said IC card come into elastic contact with corresponding contact portions of each terminal of said connector respectively, and said IC card turns on and off said detection switch.
