A mobile terminal having a terminal main body including a front case forming an internal area including a submergence area into which water is introduced and a waterproof area into which water is blocked from being introduced, and an internal frame; a first unit including a key module mounted in the terminal main body, and generating a control command when a pressing occurs, the key module being positioned in the submergence area and moving due to an external force; a second unit positioned in the waterproof area, and when the pressing occurs, generates a signal; an elastic deformation layer of which a portion is elastically deformed due to movement of the first unit, so the second unit is pressed by the first unit; and a waterproof layer attaching the elastic deformation layer and the front case so partitioning results in the submergence area and the waterproof area.

Mobile terminal

A roll-slide mobile terminal including a first frame; a second frame configured to slide with respect to the first frame in a first direction; a first roller provided in one first-direction end of the second frame; a third frame provided in a rear surface of the second frame; a flexible display unit having one end fixed to the first frame and the other end coupled to the third frame and being bent towards a rear surface when rolled around the first roller; and a drive unit configured to guide a sliding movement of the first frame with respect to the second frame in the first direction to transition the roll-slide mobile terminal from a first state in which the flexible display unit is bent towards the rear surface to a second state in which the flexible display unit is extended in the first direction, and to guide a sliding movement of the first frame with respect to the second frame in a second direction opposite the first direction to transition the roll-slide mobile terminal from the second state to the first state.

Roll-slide mobile terminal

A key module for a mobile terminal, and which includes a key having a neck part and a head key pressed to enter an input to the mobile terminal; a circuit support configured to support a circuit board having a dome terminal to be pressed when the key head is pressed for entering the input to the terminal; and a waterproof member positioned between the key and the circuit support and configured to block a moisture penetration path along a hole in a case member of the mobile terminal into which the key module is inserted.

Key module and mobile terminal having same, and method of assembling key module

There is disclosed a connector waterproof housing comprising a frame formed in a cylindrical shape having a lateral wall, an open top and an open bottom; a first waterproof portion formed in an inner rime of the lateral wall by a double-injection molding method; and a second waterproof portion formed in an outer rim of the lateral wall or one side of the frame in an ring shape so that the connector waterproof housing may solve the problem of the deteriorated waterproof reliability or the error which is caused by the pushed or rolled waterproof structure when connected with the case.
