Next, as shown in FIG. 7, the release paper 201 'of the first tape 201 is removed and the flexible printed circuit board 210 is inserted into the hole 1011. Since the flexible printed circuit board 210 of the present invention is larger in the portion 212 exposed to the outside than the portion 212 located in the front portion of the flexible printed circuit board 210, .

When the flexible printed circuit board 210 is integrally formed with the printed circuit board 185 located at the front end portion of the flexible printed circuit board 210, the size of the hole 1011 is sufficiently enlarged so that the flexible printed circuit board 210 is inserted into the hole 1011 ) From the inner inlet to the outer inlet.

A guide groove 215 (or a guide hole) corresponding to the shape of the guide protrusion 1015 may be further provided to prevent the flexible printed circuit board 210 from being shifted to the outside or the inside of the hole 1011 . Two guide protrusions 1015 are formed as in the present embodiment and the guide protrusions 1015 are formed on the left and right sides of the flexible printed circuit board 210 while passing the flexible printed circuit board 210 between the guide protrusions 1015. [ The guide groove corresponding to the shape of the guide groove can be formed.

The guide protrusion 1015 and the guide groove 215 having the above-described structure are formed so that the flexible printed circuit board 210 is not shifted inward or outward, Guides for joining.

The flexible printed circuit board 210 is attached to the first tape 201 and attaches the second tape 202 covering the upper surface of the flexible printed circuit board 210 and the upper surface of the first tape 201. [ Although the second tape 202 may have an opening similar to the first tape 201, it is preferable to use the second tape 202 in which the opening is omitted for more durable waterproofing.

At least one of the first tape 201 and the second tape 202 may include butyl. Butyl is excellent in heat resistance, cold resistance and durability, excellent in watertightness and airtightness, and excellent in waterproof performance.

And a pressing unit for pressing the upper surface of the second tape 202 to increase the adhesion between the first and second tapes 202 and the flexible printed circuit board 210. The pressing portion may be a rib protruding from the rear case 102 as in the embodiment shown in Fig. An elastic member 203 such as epoxy is further laminated on the upper surface of the second tape 202 pressed by the pressing portion so that the adhesion between the first and second tapes 201 and 202 and the flexible printed circuit board 210 Can be further improved.

9 to 11 are sectional views of a mobile terminal 100 according to another embodiment. 9 shows an antenna 118 that is mounted on the surface of the rear case 102. A flexible printed circuit board 210 is connected to the printed circuit board 185 of the full- (1011).

Two tapes 201 and 202 may be attached to the inner inlet of the hole 1011 to prevent water from flowing through the hole 1011. In this embodiment, The upper surface of the second tape 202 can be pressed through the pressing portion 230 protruding from the front case 101. [

10 is a waterproof structure of a hole 1011 connected to a side operating portion in the same manner as the embodiment shown in Fig. 4. In the present embodiment, a hole 1011 is formed in the front case 101, The inner side faces the rear surface of the display portion 151, not toward the rear case 102. The back surface of the display portion 151 presses the upper surface of the second tape 202 as the pressing portion 230. [

11 is a waterproof structure of the hole 1011 connected to the interface unit 170. The flexible printed circuit board 210 is used to connect the interface unit 170 exposed to the outside with the printed circuit board 185 of the electric field unit. do. The waterproof structure can be realized through the tapes 201 and 202 covering the inward direction inlet 1012 of the hole 1011 through which the flexible printed circuit board 210 passes.

As described above, according to at least one embodiment of the present invention, the waterproof structure can be implemented simply by using the tape, thereby reducing the manufacturing cost and simplifying the process.

It will be apparent to those skilled in the art that the present 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.
