Self-locking connection device for a card having end contact areas

摘要

A connector device is provided for receiving a smart card having a plurality of electric contact areas distributed along a forward edge. The device has a reception case having a card introduction passage with a stop limiting insertion of the card. Flexible contact blades are placed so as to bear on the areas and to exert on the card a force tending to move it away from the stop; a resilient bolt is carried by the case and cooperates with a cam formed on the end part of the card. The end part of the card, the cam means and the bolt have a construction such that full insertion of the card and return under the action of the blades cause locking of the card in a set contact position and that a second thrust exerted by the card frees the cam means from the bolt.
