Mobile terminal

摘要

Disclosed is a mobile terminal. The mobile terminal of the present invention comprises: a front case having a keypad-accommodating portion; a rear case attachably/detachably coupled to a rear surface of the front case such that a component-accommodating space, in which a main PCB is arranged, is interposed between the front case and the rear case; and a keypad which has a plurality of key buttons, and which is made of a flexible material, and which is accommodated in the keypad-accommodating portion of the front case. The keypad has an edge on which a water-resistant blade extends toward the keypad-accommodating portion. The keypad-accommodating portion has a bottom surface on which a blade insertion rain is formed to enable a portion of the water-resistant blade to be inserted into the rail. The mobile terminal of the present invention has a simple structure to enable easy manufacture and assembly, and in particular prevents water or moisture from entering a keypad area.
