Abstract: 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.

Abstract: A multi-wire data transmission cable for transmitting data signals over long distances between data devices. Presently, data devices are usually equipped with voltage interfaces for the connection of peripheral instruments. The length of data transmission lines connecting such devices is limited, due to line resistences. For transmission over long distances, signals must be converted prior to transmission and then must be reconverted after receipt of transmission. The present invention allows the connection of long transmission lines to data devices without the need of external signal converters or additional units normally required. The handle portion of the plug connection at either or both ends of the cable houses a circuit that incorporates a signal converter. No additional external units are required to connect data devices over long distances, since the converter is integrated into the cable.
