The first terminal 201 extends to the outside of the ear jack 200 and is connected to the second terminal 202 located on the side of the ear jack 200 as shown in FIG.

The first terminal 201 and the second terminal 202 may be formed by bending a plate member and the first terminal 201 and the second terminal 202 may have openings formed in the ear jack 200 Or may be formed by a double injection method with the ear jack 200.

The plurality of first terminals 201 formed on the ear jack 200 may transmit left and right sounds and perform independent functions such as converting sounds input from the microphones included in the ear set into signals and transmitting them. Recently, as the length of the plug becomes longer and the number of connection rings increases, various accessories such as an earphone and an IR remote controller can be attached in addition to a speaker.

FIG. 6 is a view showing a state where the jack 200 is coupled to the jack receiving portion 1021. FIG. The ear jack 200 is coupled to an ear jack receiving portion 1021 formed on the rear surface of the rear case 102. The jack receiving portion 1021 is recessed in a shape corresponding to the shape of the jack 200 in the front direction from the rear surface of the rear case 102.

The conventional ear jack 200 is formed on the outer side of the case 102 according to the present invention except that the ear jack 200 is located inside the case 102 and the ear jack 200 is positioned outside the electric field portion .

The ear mount portion 1021 may further include an ear jack fixing portion 1023 to prevent the ear jack 200 from being detached from the ear jack receiving portion 1021. [ The ear fixing portion 1023 covers the back face of the ear jack 200 and the jack 200 can be fixed between the ear fixing portion 1023 and the ear fixing portion 1021. [

Since the jack receiving portion 1021 is separated from the front portion, moisture introduced through the plug hole 205 of the ear jack 200 can be prevented from flowing into the electric field portion. However, it is necessary to connect the ear jack 200 where the case 102 is located on the outer side and the main board 185 provided on the inner side electrical part. Conventionally, a flexible printed circuit board is used to connect the second terminal 202 of the ear jack 200 to the main board 185, and the opening of the case 102 through which the flexible printed circuit board passes is sealed with a sealing member .

However, this method requires a flexible printed circuit board and a sealing member additionally, which increases the cost and the process. The present invention uses the antenna carrier 250 to connect the ear jack 200 and the main board 185 provided at the front end of the mobile terminal.

7 is a view showing an antenna pattern 251 and an ear jack electrode pattern 253 formed on the antenna carrier 250. As shown in FIG. The antenna carrier 250 is an apparatus for mounting an antenna on a mobile terminal in such a manner that the antenna pattern 251 is formed on the surface and is coupled to the case 102. The antenna carrier 250 is a device for mounting an antenna on a mobile terminal, Can be minimized. By using the antenna carrier 250, the antenna can be formed on the outer side of the mobile terminal to increase the transmission / reception ratio of the electromagnetic wave signal.

8 is a cross-sectional view illustrating a connection portion of the antenna carrier 250. The antenna carrier 250 is connected to the main board 185 of the mobile terminal and receives a signal to be transmitted, 185). The connection portion includes a connection rib 255 protruding from the inside of the antenna carrier 250 of the mobile terminal and a connection terminal formed on the connection rib 255. [ The connection unit is connected to the main board 185 through the case 102 of the mobile terminal.

The waterproof tape 230 is interposed between the case 102 and the antenna carrier 250 to couple the two members and prevent moisture from flowing between the case 102 and the antenna carrier 250. The waterproof tape 230 is positioned around the connection rib 255 to prevent water from flowing into the opening of the case 102 into which the connection rib 255 is inserted.

The present invention further includes an ear jack electrode pattern 253 having an antenna formed on its surface and further connecting the jack 200 and the main board 185 to the antenna carrier 250 connected to the main board 185, And the jack 200 and the main board 185 are electrically connected to each other. One end of the jack electrode pattern 253 is in contact with the second terminal 202 and the other end of the jack electrode pattern 253 is connected to the main board 185 through the connection rib 255.

9 is a cross-sectional view of an ear jack 200 according to an embodiment of the present invention. The ear jack 200 includes a second terminal 202 positioned on the side of the ear jack 200 and the ear jack electrode pattern 253 And a rib insertion portion 1025 may be further provided on the side of the second terminal 202 of the ear jack receiving portion 1021 so that the jack rib 254 is inserted thereafter. ).

The jack rib 254 is connected to the second terminal 202 of the ear jack 200 so that one end of the ear jack electrode pattern 253 can be connected to the second terminal 202 located on the side of the ear jack 200, And protrudes from the antenna carrier 250 at a position in contact with the antenna. One end portion of the ear jack electrode pattern 253 is positioned at a portion where the jack rib 254 and the second terminal 202 of the ear jack 200 are in contact with each other and then the jack electrode pattern 253 is connected to the ear jack rib 254 and the other end is connected to the main board 185 through the connection rib 255 described above.

When the second terminal 202 of the ear jack 200 faces the antenna carrier 250, the ear jack rib 254 may be provided with the ear jack electrode pattern 253 and the ear jack electrode 254 without the ear jack rib 254, Two terminals 202 are connected. However, since the jack ribs 254 are thicker than the thickness direction (the longitudinal direction in FIG. 9) in the lateral direction in which the second terminals 202 are located (the lateral direction in FIG. 9) And the thickness of the jack ribs 254 can be reduced.

5, the antenna carrier 250 may cover the rear surface of the rear case 102 to prevent the ear jack 200 exposed in the back direction of the rear case 102 from being exposed to the outside, And an ear jack hole 256 for exposing the plug hole 205 at a position corresponding to the plug hole 205 of the ear jack 200.

As described above, according to at least one embodiment of the present invention, the structure of the ear jack 200 may be provided outside the case 102 to prevent water from being introduced into the ear jack 200 through the ear jack 200. In addition, it is possible to reduce the cost by using the conventional antenna carrier 250 without using the waterproof ear jack 200 or having a separate sealing member for waterproofing the ear jack 200.

The foregoing detailed description should not be construed in all aspects as limiting 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.
