FIG. 4 is an internal perspective view showing a front key case and an intermediate case in a combined state to show an installation structure of a side key according to the present invention. FIG. 5 is a perspective view illustrating a state in which a first side key and a second side key are separated FIG. Fig. 6 is an enlarged view of a portion A in Fig. 4, and Fig. 8 is an enlarged view of a portion C in Fig.

5, a first key mounting portion 205 and a second key mounting portion 206 are respectively formed on the inside of the cases 201 and 203 for installing the first side key 231 and the second side key 232 And the switches 238 and 268 corresponding to the respective side keys 231 and 232 are provided in the key mounting portions 205 and 206, respectively. Here, the first side key 231 will be described in detail.

The switch 238 is of a form including a resiliently deformable metal dome and a substrate 239 to which a metal dome is attached, and a known switch structure can be applied. The substrate 239 may be formed of a flexible substrate or a rigid substrate. The switch 238 disclosed in this embodiment is formed in the form of a flexible substrate and is connected to the display module 251. Accordingly, the display module 251, the side keys 231, 232, and 233, and the switches 238 and 268 fixed to the front case 201 and the intermediate case 203 form a modular body connectable by one connector 201. The connector 201 is connected to the connector of the main board (not shown).

Referring to FIG. 8, the first side key 231 includes a key cap 235 having an upper key 235A and a lower key 235B integrally formed thereon. The upper key portion 235A and the lower key portion 235B are formed to have the same width as the exposed portion of the intermediate case 203, thereby being formed into a generally narrow and long shape.

The first side key 231 further includes a base plate 236 attached to the bottom surface of the key cap 235. The base plate 236 is formed to have a flange shape at least by being formed wider than the bottom surface of the keycap 235.

The keycap 235 and the base plate 236 may be formed of a metal material, such as stainless steel, for example. Preferably, the base plate 236 is attached to the cap 235 in the form of spot welding. By doing so, the first side key 231 can be prevented from being easily scratched or scratched from external friction or impact, and the first side key 231 can be prevented from being detached due to the rigidity possessed by the base plate 236 .

8, on the surface of the switch 238 operated by the first side key 231, a pushing protrusion 240 is attached so that the switch 238 can be easily pressed. The pushing protrusion 240 may be formed in a silicone-type so as to be easily attached to the surface of the switch 238 formed of a metal material.

In such a structure, when a pushing protrusion for operating the switch 238 is provided on the lower surface of the first side key 231 having a narrow width on the side exposed portion of the intermediate case 203, the adhesive force of the pushing protrusion is weak It is effective in reducing risk and increasing durability.

The spacer 237 can be mounted between the base plate 236 and the substrate 239 of the switch 138 so that the first side key 231 can reduce the noise due to the vibration with the first key mounting portion 205 have. The spacer 237 may be formed of a material such as elastic rubber, silicone, foam resin or the like, and may be installed while being pressed between the base plate 235 and the substrate of the switch 238. The spacer 237 may be attached to the base plate 235 by an adhesive or a tape.

9 is an exploded perspective view of the second side key, Fig. 10 is an exploded perspective view of the second side key disclosed in Fig. 9, and Fig. 11 is an exploded perspective view of the second side key, 12 is a cross-sectional view taken along the line XII-XII in Fig. 11. Fig.

As shown in these drawings, the second side key 232 includes a key cap 260 having a guide hole 260a formed in a part of the bottom surface thereof, a base plate 261 attached to the bottom surface of the key cap 260, One end is movably restrained along the guide hole 260a and the other end includes an actuating member 265 rotatably connected to the cases 201 and 203. [

The keycap 260 and the base plate 261 may be made of a metal material such as stainless steel as in the first side key 231 and the base plate 261 may be attached to the bottom surface of the keycap 260 by welding . The guide hole 260a formed in the keycap 260 is configured to allow the first portion 265a of the actuating member 265 to be inserted therein. When the first portion 265a is mounted on the guide hole 260a One end of the actuating member 265 is restrained by the key cap 260 by spot welding the base plate 261 to the bottom surface of the key cap 260.

The guide hole 260a has a height at least greater than the diameter of the first portion 265a so that the first portion 265a of the operation member 265 can be easily moved, The first portion 265a has a width allowing the distance that the first portion 265a moves. The operation member 265 serves as a 'stabilizer' for preventing the keycap 261 from being tilted to one side when a pressing force is applied to the keycap 260, The length of the keycap 260 may be greater than half of the length of the keycap 260. [

The operating member 265 includes a connecting portion 265c connected to both ends of the first portion 265a and a second portion 263c connected to the connecting portion 265c and formed in parallel with the first portion 265a, (Not shown). The second portion 265b is rotatably engaged with the cases 201 and 203. [ 10, the first portion 265a and the second portion 265b are formed along the first axis Y1-Y1 and the second axis Y2-Y2, which are parallel to each other, The second part 265b is rotated only in the case 201 while the key 232 is pressed or restored while the first part 265a is engaged with the guide hole 260a of the keycap 261 As shown in FIG.

Such an operation member 265 overcomes the friction or poorly pressed phenomenon caused by biasing of the force when the second side key 232, which has a length longer than the width, is pressed. The first portion 265a of the operation member 265 is in parallel with the second portion 265b even when the second side key 232 is pushed away from the center of the keycap 261 The other portion of the keycap 261, which is not directly subjected to the force, is also rotated at the same speed as that of the directly pressed portion. Therefore, it is possible to facilitate smooth operation of the side key in a mobile terminal equipped with a narrow side key as in the present disclosure.

The shape and structure of the operation member 265 can be variously modified within the spirit of the present invention. For example, the operation member 265 may be formed in the shape of a bracket having a specific surface, instead of being formed in the shape of a bent wire as shown in FIG. 10, and the number of the operation members may be plural.

10, a pushing protrusion 263 capable of operating a switch is attached to the surface of the base plate 261. As shown in Fig. That is, contrary to the pushing protrusion 240 formed on the switch 238 of the first side key 231 shown in FIG. 5, the pushing protrusion 263 of this embodiment is also formed on the base plate 261 5.

The pushing projection 263 can be attached to the base plate 261 by means of an adhesive or a double-sided tape 264.

FIGS. 13A and 13B show an operation state of the second side key related to the present invention, wherein FIG. 13A shows a state before the second side key is depressed, and FIG. 13B shows a state where the second side key is depressed.

13A, the surface of the second side key 232 has a contour on a curved surface so that it can be matched with the curved side surface formed by the front case 201 and the rear case 202.

When the keycap 261 of the second side key 232 is pressed, the pushing projection 263 is also moved in the depressed direction to operate the switch 268. 13B, the second portion 265b of the operating member 265 is engaged with the case 201, so that the first portion 265a is rotated counterclockwise. In this process, the first portion 265a of the actuating member 265 is freely moved in the guide hole 260a.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
