The first bracket 201 includes a seating part 210 that engages with the rear surface of the display unit 151 and includes a metal plate 205 for supporting rigidity of the display unit 151. The metal plate 205 may be formed to be exposed on the bottom surface of the seating part as shown in FIG. 5 and directly contact with the back surface of the display part 151.

The second bracket 202 extends downward from the first bracket 201 and engages with the user input unit 131 located at the lower end of the display unit 151 and the interface unit 170. Since the electronic parts mounted on the second bracket 202 are not as large in area as the display part 151, the concave and convex parts are required to be suitable for the parts mounted on the surface of the bracket 200, It is possible to realize the concavity and convexity and to partially expose the portion where the energizing structure is required.

The third bracket 203 extends upward from the first bracket 201 and can seat the audio output unit 152 and the camera 121 located at the upper end of the display unit 151.

The metal plate 205 is attached to the surface of the bracket 200 in a portion where the circuit board of the user input portion 131 is seated, the interface coupling portion 240, a guide hole 235 to which a conductive gasket 230 to be described later is coupled, Exposed.

First, the bracket 200 and the display unit 151 will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a rear view illustrating a front case 101 of a mobile terminal according to an embodiment of the present invention. FIG. 7 is a perspective view illustrating a bracket 200 and a display unit 151 of a mobile terminal according to an embodiment of the present invention. Fig.

6, the mobile terminal includes a conductive pattern 260 made of a conductive material at an inner circumference of a through-hole 101a of a case 100, that is, a portion of the case 101 where the display unit 151 is in contact. The conductive pattern 260 may partially form a conductive material such as a metal on the inner surface of the front case 101 by a sputtering method. The energizing pattern 260 is brought into contact with the display unit 151 and the static electricity flowing into the display unit 151 is bound to the energizing pattern 260 without being transmitted to the display 151. [

The static electricity bound to the energizing pattern 260 can be discharged through the metal plate 205 of the bracket 200 and can be electrically connected to the metal plate 205 of the bracket 200 As shown in FIG. 5, an extrudate 204 is partially formed, and a conductive gasket 230 is attached to a portion of the metal plate 205 exposed on the surface of the bracket 200.

The electrostatic discharge does not affect the display unit 151 since the electroconductive gasket 230 is formed to be spaced apart from the display unit 151 so that the first gasket 201 To the second bracket 202 extending downward.

When the conductive gasket 230 is formed on the second bracket 202, as shown in FIG. 6, the conductive pattern 260 may be formed to extend downward from the periphery of the display 151, Can be formed to extend.

The conductive gasket 230 is a member for compensating a distance between the metal plate 205 of the bracket and the energizing pattern 260 formed in the case. Since the metal plate 205 of the bracket 200 is in contact with the rear surface of the display unit 151, the metal plate 205 of the bracket 200 is spaced apart from the conductive pattern 260 formed on the inner circumference of the through- do.

In addition, since a tolerance may be generated when the bracket 200 and the front case 101 are coupled, the tolerance can be compensated by using a material having elasticity and deformable in shape.

It is preferable that the conductive gasket 230 protrude forward from the front surface of the bracket 200 before being coupled to the front case 101. When the front case 101 and the bracket 200 are coupled with each other, the conductive gasket 230 is pushed and electrically connected between the conductive pattern 260 and the metal plate 205.

The conductive gasket 230 may be coupled to a portion of the metal plate 205 exposed through the guide hole 235 as shown in FIG. The guide hole 235 is necessary to fix the metal plate 205 in the correct position of the mold frame during double injection molding. The inner side of the guide hole 235 is exposed to the inside of the guide hole 235 without covering the metal plate 205 with the injection molded product 204 and the conductive gasket 230 can be attached to the exposed position have.

7, a structure is shown in which a conductive pattern 260 of a front case 101 and a metal plate 205 of a bracket 200 are connected to each other through a conductive gasket 230. FIG. 6, the static electricity bound to the energizing pattern 260 of FIG. 6 without being able to move to the display portion 151 is generated by the energizing pattern 260 (see FIG. 7) Through the conductive gasket 230 and the metal plate 205. As shown in FIG.

8 is a cross-sectional view showing a bracket 200 and a receiver of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 8, static electricity applied to the acoustic output unit 152 of the present invention is applied to a metal plate (205), as will be described below.

8, the sound output unit 152 includes an acoustic hole 109a formed on the window glass 109 coupled to the front surface of the front case 101 and a sound hole 109b formed on the back surface of the acoustic hole 101b of the front case 101 do. The acoustic holes 109a and 101b may be formed only in the front case 101 or in the window glass 109 only.

8, when the static electricity is applied to the acoustic output unit 152 through the acoustic holes 109a and 101b, the acoustic output unit 152 is damaged. Thus, the acoustic hole 101b and the acoustic output unit 152 And a metal mesh 270 is interposed between them.

The metal mesh 270 is a net structure made of a metal material, and can transmit a sound but can be made of a conductive material to hold static electricity input to the sound output unit 152. This is a principle similar to the energizing pattern 260 described above.

Since the acoustic output unit 152 is completely exposed through the acoustic hole 101b unlike the display unit 151, the static electricity applied to the acoustic output unit 152 only by the energizing pattern 260 formed on the back surface of the front case 101 The metal mesh 270 is used to cover the acoustic hole 101b.

The end of the metal mesh 270 is disposed adjacent to or in contact with the metal plate 205 of the bracket 200. The static electricity drawn through the acoustic hole 101b can be moved to the metal plate 205 through the metal mesh 270 without moving to the acoustic output unit 152. In this case, do.

Or the metal mesh 270 may be electrically connected to the metal plate 205 of the bracket 200 through the conductive pattern in contact with the conductive pattern 260 formed on the inner side of the front case 101 described above.

9 is a cross-sectional view illustrating a bracket 200 and a circuit board 185 of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 9, the static electricity applied to the circuit board 185 of the mobile terminal Will move to the metal plate 205.

The circuit board 185 is a plate-shaped member having a circuit pattern for transmitting electrical signals between the components of the mobile terminal. Although a rigid material may be used, for the utilization of a narrow space, a flexible material is used It is possible.

Since electric signals are transmitted through the circuit pattern formed on the circuit board 185, if static electricity is applied, such a signal system is interrupted, and if the circuit pattern is broken, it may cause a failure. In addition, since static electricity may be transmitted to other components through the circuit board 185, a structure that can prevent such static electricity is needed.

The circuit board 185 may be in contact with the surface of the bracket 200 as shown in Fig. However, since the metal plate 205 is covered by the injection-molded article 204 of the bracket 200, the circuit board 185 can be contacted with the integrated circuit board 185 when the metal plate 205 is exposed to the surface. It may not directly contact the metal plate 205.

In this case, a screw 280 made of a metal material passing through the circuit board 185 is used to fasten the bracket 200 so as to come in contact with the metal plate 205. That is, the circuit board 185 is fixed to the bracket 200 through the screw 280, and electrically connected to the circuit board 185, so that the static electricity applied to the circuit board 185 can escape through the metal plate 205.

As described above, according to at least one embodiment of the present invention, since the static electricity applied to the display unit of the mobile terminal is provided with the energizing structure to allow the static electricity to escape through the metal plate of the bracket, Can be prevented.

In addition, the static electricity directly flowing into the sound output portion can be bypassed through the bracket, thereby reducing the damage caused by the static electricity of the sound output portion.

Further, the static electricity applied to the circuit board is bypassed through the energizing structure that electrically connects the circuit board and the metal plate of the bracket, thereby preventing malfunction and damage of the mobile terminal due to static electricity.

It will be apparent to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
