  • Dual memory card type socket
    Patent number: 8827727
    Abstract: The Present Disclosure has the effect of maximizing space utilization in the internal space of the socket during mounting/unmounting. In addition, the Present Disclosure enables attachment/removal within a minimal space, because the extraction stroke for a first memory card is so short. Also, the Present Disclosure can reduce the total socket height because the second memory card contact terminal and the first memory card contact terminal alignments do not overlap. Furthermore, the Present Disclosure has the advantage that cellular telephone OS errors do not occur, because the second memory card cannot be removed at will when the mobile communication terminal is powered on, with battery installed.

  • Socket for micro subscriber identification module card
    Patent number: 8608494
    Abstract: A micro SIM card socket is equipped with an insulator housing, wherein the SIM card is installed; a metal shell, connected to the housing at a constant distance from the housing, that guides the insertion of the SIM card; multiple contact terminals, supported by the housing, one end of which is connected to the contact terminal of the SIM card and the other end of which is fixed to the printed circuit board; a locking unit installed on the side of the housing in order to selectively fix the insertion point of the SIM card, having a curve-shaped pressure pin, at the end of the unit, putting pressure to the edge of the SIM card; a detect terminal installed in the housing in order to detect the insertion of the SIM card and that is pressured by the pressure pin, located in proximity of the pressure pin, when the SIM card is inserted; and a switch terminal that elastically contacts the detect terminal.
