<p>The present invention relates to a socket structure for coupling a SIM card to a smartphone, a cellular phone, and a portable terminal and, more specifically, to a socket structure in a tray insertion way, capable of stably fixing a tray by a pressing method using a ball when the tray with a card therein is inserted and installed in the socket structure of a terminal for communication with the card. The present invention prevents a configuration for supporting the tray and transmitting a clamping force from being damaged or transformed so as to improve the reliability of the coupling of the socket and the tray. Further, the present invention clearly detects that the tray is coupled in a right position accurately and a user easily recognizes that detection immediately, thereby preventing excessive additional pressure.</p> |
