The sealing member 130 extends along a second direction, which is a direction in which the rear case 102 and the battery cover 103 are formed. The extension part 133 extending along the second direction is formed with an adhesive member 145 for fixing the sealing member 130. That is, the extension portion 133 is formed like a wing along the second direction at a middle point between the first and second second projections 131 and 132, and an adhesive member 145 is formed on the extension portion 133 . The adhesive member 145 may be a double-sided tape and fixes the inner surface of the battery cover 103 and the extension portion 133 by bonding them. At this time, a sheet 146 made of PET (polyethylene phthalate) is formed between the adhesive member 145 and the extension 133 to improve the adhesive force of the adhesive member 145.

At this time, a first recess portion 102a is formed on the outer side surface of the rear case 102 to be recessed toward the inside, and a second recess 102b is formed on the inner side surface of the battery cover 103, A portion 103a is formed. The first and second recessed portions 102a and 103a may be formed to face each other and the first and second recessed portions 102a and 103a may have first and second second projecting portions 131, 132) are accommodated so that the direction in which moisture is introduced is changed so as to be sealed more firmly.

The extension portion 133 is formed to have an area of a predetermined size for attaching the adhesive member 145 and the sheet 146. In FIG. 2, the first protrusion 131 is formed to have a slightly pointed shape such as an incinerator, and the second protrusion 132 is formed to have a slightly gentle circular shape. However, it is needless to say that at least one of the first and second second protrusions 131 and 132 may be sharp or circular. At this time, the first protrusion 131 should be in close contact with the rear case 102, so that the first protrusion 131 and the rear case 102 are overlapped by design. More specifically, the first protrusion 131 may come in close contact with the first recess portion 102a to have a somewhat distorted shape, which is also true of the second protrusion 132. That is, the second protrusion 132 may come into close contact with the battery cover 103, more specifically, the second recess 103a, so that the end of the second protrusion 132 may be somewhat distorted. In this way, the first and second second projections 131 and 132 are overlapped with each other in a somewhat collapsed shape in the first and second recessed portions 102a and 103a, so that the sealing can be more firmly performed.

4, an adhesive member 145, a sheet 146, and a sealing member 130 are stacked in this order on the inner surface of the battery cover 103, and have shapes corresponding to each other. That is, the adhesive member 145, the sheet 146, and the sealing member 130 have a substantially rectangular frame structure in which the interior is empty.

In addition, the adhesive member 145, the sheet 146, and the sealing member 130 are preferably connected without breaking. If there is a break in one part of the adhesive member 145, the sheet 146 and the sealing member 130, the sealing performance will deteriorate.

5B and 5C show a second recess 103a in which the height of the second protrusion 132 (the height of the second protrusion 132 in the semicircular shape A radius of the semicircle), and the width is formed to be wider than the area where the sealing member 130 is formed. In addition, as shown in FIG. 5C, a wing 134 protruding toward the second recess 103a may be formed on one side of the sealing member 130. As shown in FIG. The wing portion 134 flows toward the water inflow path L1 shown in FIG. 2, so that the water passing through the second projection portion 132 and the second recess portion 103a does not directly descend, So that it is possible to more firmly prevent the inflow of water.

6B, the sealing member 130 according to an embodiment of the present invention has the first protrusion 131 and the second protrusion 132 in a substantially 'A' shape, and the first and second protrusions 131 and 132 ' 2 extension portions 133 are formed between the second projections 131 and 132. [ 6B, the second protrusion 132 may have a semicircular shape in section, but may have a wedge shape like the first protrusion 131, and the first and second protrusions 131 and 132 may have a wedge shape. The sealing member 130 may have a substantially T-shaped cross-section.

The sealing member 130 forms a rectangular sealing area therein.

The embodiments related to FIGS. 2 to 6B described above will be referred to as a first embodiment, and the second and third embodiments will be described below. The sealing structures of the second and third embodiments are the same as those of the first embodiment, and it can be understood that only the types of the first frame and the second frame are changed.

FIG. 7 shows an application example of the sealing member 130 according to the second embodiment of the present invention, wherein the sealing member 130 is applied to the first sound output unit 152a. Referring to FIG. 7, a plate 156 on which a sound hole 157 is formed is disposed on a lower surface of a window 151a formed on a front surface of the mobile terminal. The moisture introduced through the acoustic hole 157 moves toward the acoustic output module 152a disposed inside, and the dotted line represents the inflow path L2 of moisture. Since the sound output module 152a itself has a waterproof function, the moisture introduced into the sound output module 152a through the sound hole 157 is not a problem. However, if moisture is introduced into the body 152c surrounding the sound output module 152a, the printed circuit board, the flexible circuit board, or other electronic components inside the mobile terminal may be adversely affected. In order to prevent this, a recess 152d is formed on the upper surface of the body 152c, and a sealing member 130, an adhesive member 145, The sheet 146 is disposed so that moisture does not penetrate into the outer region of the sealing member 130. At this time, an adhesive member 145 is attached to the upper surface of the body 142c, a sheet 146 is provided between the adhesive member 145 and the sealing member 130, 151a and the upper surface of the body 152c. The waterproof principle is the same as in FIGS. 2 to 6B described above, so a detailed description thereof will be omitted.

8 is a view for explaining an application example of the sealing member 130 according to the third embodiment of the present invention. In the third embodiment, the second sound output section 152b, which is a speaker module, ) May be applied. The second sound output unit 152b is formed on the rear surface of the mobile terminal.
