  • Patent number: 7967640
    Abstract: A card connector according to the present invention includes a bottom wall of a base member configured to support a plurality of contacts in a cantilever manner. A rectangular SIM card is inserted into the card connector in such a manner that the shorter side of the card is parallel to the direction of insertion. The plurality of contacts of the card connector are arranged to correspond to respective plural external contact points of the SIM card. Each of the contacts includes a contact portion, two elastic deformation portions, and a terminal portion. The two elastic deformation portions of the contact are coupled together so as to substantially form an isosceles triangle shape with a vertex angle ?1 at a vertex corresponding to the contact portion. The plurality of contacts are arranged parallel to one another, each in an inverted V shape with respect to the card insertion direction.

  • Patent number: 7867034
    Abstract: A card insertion slot in the card connector through which two types of cards, large and small cards, can be selectively installed in a card accommodation space include first and second guideways in corresponding to the sizes of the cards. The card connector includes first and second contacts, a lock bracket configured to detect the width of the large card, an actuator configured to be rotatable, and a partition member including a partition plate configured to be movable. When the large card is inserted into the card connector, the lock bracket is moved from the first position to the second position. When the large card is further fed into the card connector, the actuator is rotated from the first position to the second position, and the partition plate is moved from the first position to the second position.
