SIM CARD FIXATION DEVICE AND MOBILE COMMUNICATION TERMINAL Russian patent published in 2017 - IPC H05K1/18 

FIELD: information technologies.

SUBSTANCE: disclosed invention relates to SIM card fixation means and mobile communication terminal. SIM card fixation device is made in terminal, provided with SIM-card, and comprises: card tray to support SIM card, card holder to support card tray, when card tray is installed in terminal, and card tray fixation locking mechanism, wherein card holder is provided with first resilient component, made with possibility to apply pushing force in direction from terminal to card tray, when SIM card is withdrawn, locking mechanism containing pressure component, locking rod and second resilient component, locking rod is equipped with lock closer, while card tray is provided with closing part, and when card tray supporting SIM card, is installed in terminal, lock closer and closing part form interface resistance, preventing card tray extraction, pressure component is provided with drive surface in contact with locking rod. Drive surface is made with possibility to push locking rod to move when pressing on pressure component, thus actuating lock closer on locking rod to move, to extract card tray, eliminating interfacing resistance between closing part and lock closer, and second resilient component is connected with locking rod and made with possibility to return locking rod into initial position after, that card tray is removed. Locking mechanism additionally comprises third resilient component, corresponding to pressure component, and made with possibility to return pressure component into initial state under action of its elastic force of third after pressing on it. Said device is part of corresponding mobile communication terminal.

EFFECT: disclosed invention enables to increase ease of SIM card insertion and removal.
