<p>Disclosed are a SIM card socket and its manufacturing method, in which board-engaging free ends and card-engaging free ends of pin contacts of the SIM card socket are disposed within the outer dimensions and extend inwardly of the SIM card socket, thereby reducing the dimension of the mobile communication device. The SIM card socket has a plurality of U-shaped pin contacts mounted in a socket housing. Each of the pin contacts has a bight portion, a board-engaging free end and a card-engaging free end. The board-engaging free end and the card-engaging free end extend in the same direction away from the bight portion and define an acute angle therebetween. The socket housing has through hole windows, in which the board-engaging free ends and the card-engaging free ends of the pin contacts are located, so that the board-engaging free end and the card-engaging free end are located within the dimensions of the socket housing. The board-engaging free ends and the card-engaging free ends elastically come into contact with contacts of a printed circuit board of the mobile communication device and the SIM card, respectively. The card socket further includes a metal reinforcement to strengthen the socket housing.</p> |
