The fixing sheet 410 is not particularly limited, but for example, a PC sheet (Polycarbonate) may be used as the fixing sheet 410. In addition, when the fixing sheet is attached, a waterproof tape may be used to prevent the water from entering the attachment surface.

6A and 6B, the rubber 420 is attached to a lower surface of the fixing sheet 410, and a protrusion 422 is formed on the lower surface of the rubber 420 to protrude toward the first drainage line 310. do.

Accordingly, the protrusion 4220 of the rubber 420 is inserted into the first drain line 310 and compressed, thereby preventing water from entering the accommodating part 103. The rubber 420 is not particularly limited, but a silicone or other elastic material may be used.

On the other hand, as described above, since the drain line 300 guides the water penetrated between the rear case 102 and the cover member 200 to the outside of the mobile terminal 100, the sealing member 400 is the first drain line ( 310) should be provided so as not to seal completely.

To this end, the sealing member 400 is inserted into the inner end face of the first drain line 310 adjacent to the receiving part 103 and compressed, and the water penetrated through the outer end face of the first drain line 310 is compressed. Can be guided.

The sealing member 400, more specifically, the protrusion 422 of the rubber 420, faces the inner end surface of the first drain line 310, not the center of the first drain line 310, as shown in FIG. 6A. It may be extended.

In addition, since the protrusion 422 is elastically deformed in the horizontal direction by being pressed by the first drainage line 310 as shown in FIG. 6B, the protrusion 422 does not come into contact with the inner wall of the first drainage line 310 during compression. It is preferably formed to be spaced apart a predetermined distance.

As such, the protrusion 422 of the rubber 420 is formed to be inserted into the inner end surface of the first drain line 310 and compressed, thereby preventing water from entering the receiving part 103 from the first drain line 310. In addition, the intruded water may be guided to the second drain line 320 along the outer cross section of the first drain line 310 which is not sealed by the rubber 420.

That is, the sealing member 400 functions as a sealing means for preventing the water guided by the drain line 300 from entering the electronic component of the receiving part 103 or the mobile terminal 100 through the drain line 300. do.

On the other hand, the water guided to the end of one surface of the case (101, 102) by the above-mentioned drainage line 300 should be finally discharged to the outside of the mobile terminal 100 may be provided for this structure.

For example, the separation groove 210 communicates with the drain line 300, and the water guided by the drain line 300 may be discharged to the outside of the mobile terminal 100 through the separation groove 210.

As shown in FIG. 7, when the separation groove 210 and the ends of the second drain line 320 communicate with each other, the water guided to the separation groove 210 by the second drain line 320 is separated from the groove 210. It may be discharged to the outside of the mobile terminal 100 through.

In particular, the separation groove 210 may be formed in the lower portion of the outer peripheral surface of the cover member 200, the water may be guided to the separation groove along the drain line by gravity.

Referring to FIG. 4, the separation groove may be formed at the bottom of the outer circumferential surface of the cover member 200. Accordingly, when the user uses the mobile terminal 100 for a call or other purpose, the separation groove 210 naturally moves to the mobile terminal. It is located at the bottom of the (100).

As a result, the water guided by the drain line 300 may be naturally guided to the separation groove 210 along the drain line 300 by gravity and discharged to the outside of the mobile terminal 100.

That is, the separation groove 210 is in communication with the drain line 300, the separation groove 210 functions as a discharge means for discharging the water guided by the drain line 300 to the outside of the mobile terminal (100).

As such, by using the separation groove 210 as a discharge means without providing a separate discharge port, the manufacturing process can be simplified and space utilization of the cover member 200 can be increased. However, the present invention is not limited thereto, and in addition to the separation groove 210, a separate discharge means may be provided and utilized.

On the other hand, since the sealing member 400 is inserted into the first drain line 310 and compressed to prevent water from invading the accommodating part 103, the sealing force of the sealing member 400 is enhanced to enhance the mobile terminal. Consider improving the waterproof performance.

To this end, the case (101, 102) in the mobile terminal 100 according to an embodiment of the present invention includes an inner hook groove 109 is provided adjacent to the drain line 300, the cover member 200 is It may include an inner hook 240 is inserted into the inner hook groove 109 is fixed.

Referring to FIG. 5, the rear case 102 is provided with at least one inner hook groove 109 adjacent to the first drain line 310, and the cover member 200 is inserted into and fixed to the inner hook groove 109. One or more inner hooks 240 may be provided.

Here, the inner hook groove 109 may be provided in the inner region of the first drainage line 310 corresponding to the receiving portion 103 as shown in FIG. 5, but is not limited thereto. It may also be provided in the outer region of 310.

As such, the inner hook groove 109 and the inner hook 240 may be provided to increase the coupling force between the rear case 102 and the cover member 200. Accordingly, the assembly tolerance between the rear case 102 and the cover member 200 may be reduced, and the pressing force with respect to the first drain line 310 of the sealing member 400 may be increased. As a result, the waterproof performance of the mobile terminal 100 can be improved.

On the other hand, the configuration not described herein is a battery seating groove 190a, a battery terminal 190b, a smart card socket 500 and the memory card socket 600 and the like shown in FIG.

The mobile terminal 100 described above is not limited to the configuration and method of the embodiments described above, the embodiments are a combination of all or part of each embodiment selectively so that various modifications can be made Can be configured.
