  • Smart card connector
    Patent number: 5470260
    Abstract: An electrical connector for electrically connecting to conducting circuit traces on a card, includes contact wheels rotatably mounted on resilient cantilever arms. The wheels project into a card receiving slot of the connector such that when the card is inserted therein, the wheel contacts are resiliently biased out of the slot to press against a surface of the card, whereby further insertion thereof causes the contact wheels to roll over the surface of the card thereby avoiding rubbing of the contact surfaces whilst nevertheless maintaining suitable contact pressure.
