The printed circuit board 182 transmits signals to the display unit 151 and the sound output module 152 of the mobile terminal so as to provide information to the user and controls the touch sensor 137, the camera 121, the microphone 122 ) Or the like, or stores the data in the storage unit.

The printed circuit board 182 is included in the controller 180, and various electronic elements 183 are mounted on the substrate on which the circuit pattern is printed. The position where the electronic element 183 is mounted and the position where the circuit pattern is formed are conventionally formed to avoid the formation of the card mounting portion 165. The present invention has the shield can 166 covering the upper surface of the electronic element 183, And the data card 164 is seated on the upper surface of the shield can 166.

The card connecting terminal 167 is mounted on the printed circuit board 182 adjacent to one side of the shield can 166. One side of the data card 164 is seated on the shield can 166 and the other end And is seated on the upper surface of the card connection terminal 167 so as to be connected to the card connection terminal 167.

At this time, the card connecting terminal 167 can be disposed at a position protruding from the printed circuit board 182 at a height corresponding to the height of the shield can 166. The other side can be seated on the card connecting terminal 167 when one side of the data card 164 is placed on the shield can 166 by fitting the height of the card connecting terminal 167 to the height of the shield can 166. [

At this time, the rear case 102 is formed with a card mounting hole 102 'for exposing at least a part of the card connecting terminal 167 and the shield can 166. The shield can 166 and the card connection terminal 167 are exposed to the backside through the card mounting hole 102 '.

And a terminal cover 168 for fixing the data card 164 to the card connection terminal 167 so that the connection with the card connection terminal 167 is maintained when the data card 164 is mounted on the mobile terminal 100 have. The terminal cover 168 is spaced apart from the card connection terminal 167 and is located on the upper surface of the card connection terminal 167. The height of the spacing space for inserting the data card 164 into the spacing space is determined by the data card 164).

One side of the data card 164 is inserted between the card connecting terminal 167 and the terminal cover 168 and the other side is seated on the upper surface of the shield can 166 as shown in Fig. That is, the data card 164 is placed on the upper surface of the shield can 166 and is pushed in the direction of the card connection terminal 167 to mount the data card 164 and push in the opposite direction to separate the data card 164.

An inclined surface 169 may be provided on the other side of the shield can 166 to facilitate detachment of the data card 164. The inclined surface 169 is inclined to be lowered from the other side to one side. The data card 164 is pushed toward the card connecting terminal 167 along the inclined surface 169 when the data card 164 is mounted and the other side of the data card 164 is moved along the inclined surface 169 when the data card 164 is separated So that the user can hold the other side of the data card 164 and is easy to separate.

The inclined surface 169 may be formed by partially varying the thickness of the shield can 166 and may be formed by pressing the shield can 166 outward inside the shield can 166 as shown in FIG.

5 is a cross-sectional view showing a card mounting portion 165 of the mobile terminal 100 according to another embodiment of the present invention. The other side of the data card 164 is seated on the upper surface of the shield can 166 seated on the printed circuit board 182 and one side of the data card 164 is contacted to the card connecting terminal 167. [ .

However, the terminal cover 168 'for retaining the connection of the data card 164 with the card connection terminal 167 is formed of a separate member different from the above-described embodiment and is not mounted on the printed circuit board, 5, a part of the rear case 102 is protruded in the direction of the card mounting hole 102 'to form the terminal cover 168'. The distance between the top surface of the card connection terminal 167 and the terminal cover 168 'formed by protruding the rear case 102 corresponds to the thickness of the data card 164.

Unlike the case in which the inclined surface 169 for guiding the mounting and separation of the data card 164 in the above-described embodiment is formed in the shield can 166, the inclined surface 169 'of this embodiment is the same as the card mounting hole 102' Is connected to the shield can (166) from the surface of the rear case (102) at a portion adjacent to the other side of the shield can (166). The inclined surface 169 'has the same function as the inclined surface 169 of the above-described embodiment.

FIG. 6 is a perspective view showing a rear cover 103 separated from the rear surface of a mobile terminal according to another embodiment of the present invention, and FIG. 7 is a perspective view of a card mounting portion 165 of the mobile terminal 100 according to another embodiment of the present invention Fig. The mobile terminal 100 according to the present embodiment is a watch-shaped mobile terminal, i.e., a watch phone, which can be wound around a user's wrist.

It is difficult to secure the space to be seated on the printed circuit board 182 and to mount the data card 164 because the area of the watch-phone is particularly limited. In the present invention, the data card 164 can be mounted on the watch phone by implementing the layered structure using the shield can 166. [

6, when the detachable rear cover 103 is detached from the back surface of the watch phone, a card mounting portion (not shown) for mounting the data card 164 through the card mounting hole 102 'of the rear case 102 165 are exposed.

Referring to FIG. 7, a display unit 151 is disposed on a front surface, a battery 191 is disposed on a rear surface of the display unit 151, and a printed circuit board 182 is disposed on a rear surface thereof. The printed circuit board 182 can be disposed on the battery 191 rather than the printed circuit board 182 arranged side by side with the battery. Although not shown in the drawings, a printed circuit board 182 may be additionally provided between the display unit 151 and the battery 191. [

7, the shield can 166 covers the electronic elements 183 and the like mounted on the printed circuit board 182, is seated on the printed circuit board 182, and is disposed adjacent to one side of the shield can 166 And a card connection terminal 167 is provided on the printed circuit board 182. [

One side of the data card 164 may be mounted on the card connecting terminal 167 and the other side may be mounted on the shield can 166 and further include a terminal cover 168 for fixing the data card 164. The inclined surface 169 is provided on the other side of the shield can 166 to guide the mounting and dismounting of the data card 164.

As described above, according to at least one embodiment of the present invention, the area of the printed circuit board 182 necessary for mounting the data card 164 can be minimized, and the size of the mobile terminal can be reduced.

Also, the data card 164 can be mounted on a watch phone having a small size, and a USIM card or a memory card can be added to a mobile terminal of a small size, so that the function of the mobile terminal can be expanded.

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.
