Therefore, when external shock is repeatedly applied, there is a fear that the connecting portion is broken.

In order to prevent the breakage and reinforce the boss 250, a reinforcement part 260 is provided. The reinforcement part 260 is connected to the boss 250 and inserted into the through hole 211 formed in the frame 210 so as to be caught by the inner wall 212 forming the through hole 211 during an external impact. Support and reinforce the boss 250.

In the above description, the frame 210 accommodates the display 230 and is coupled to the rear case 102 through the boss 250, but is not limited thereto. The frame may be any frame that forms an internal or external frame of the mobile terminal 100, and the boss reinforcement structure described below may be applied to any structure having a boss connecting a plurality of frames.

Hereinafter, the reinforcing structure of the boss 250 and the mobile terminal 100 having improved durability by providing the same will be described in more detail.

5 and 6 are exploded perspective and sectional views showing one embodiment of the boss reinforcement structure shown in FIG. 4, respectively.

5 and 6, the printed circuit board 220 is disposed to cover the frame 210. Various electronic devices are electrically connected to the printed circuit board 220, and the printed circuit board 220 may be configured as an example of the controller 180 (see FIG. 1) for controlling the overall operation of the mobile terminal 100. .

The through hole 211 is formed in the frame 210. The inner wall 212 of the frame 210 forming the through hole 211 is formed so that the reinforcement portion 260 formed to reinforce the boss 250 may be caught by an external impact. The through hole 211 is formed along the circumference of the printed circuit board 220 so that the boss 250 and the reinforcement part 260 may limit and support the movement of the printed circuit board 220.

The boss 250 is formed to protrude from one surface of the frame 210 so as to penetrate the printed circuit board 220. The boss 250 has a hollow shape that shares a central axis with the through hole 211. The boss 250 may have, for example, a hollow cylindrical shape.

The boss 250 is configured to couple the frame 210 and another frame (for example, the rear case 102 shown in FIG. 4) to be coupled to the frame 210, and to connect the printed circuit board 220. It is formed to support. For example, the outer circumferential surface of the boss 250 may be in surface contact with the side surface of the printed circuit board 220 during an external impact, thereby supporting the printed circuit board 220 and limiting movement.

The reinforcement part 260 is inserted into the through hole 211 and is configured to reinforce the boss 250 in at least one direction of force applied by the printed circuit board 220 to the boss 250. In detail, the reinforcement part 260 extends from one end of the boss 250 and is disposed to cover the other surface of the frame 210. The force in at least one direction refers to a force in the axial direction that intersects the central axis of the boss 250 among the forces applied to the boss 250 by the printed circuit board 220 during an external impact, and is applied to the central axis of the boss 250. It may be a force in the shear direction applied in a direction perpendicular to the direction.

Referring to the drawings, the boss 250 and the reinforcement portion 260 may be formed in an integrated T-shape. The portion inserted and exposed in the through hole 211 functions as the boss 250, and the portion inserted into the through hole 211 is caught by the inner wall 212 forming the through hole 211, and is disposed in the boss 250. ) As a reinforcing portion 260 to reinforce).

Between the other surface of the frame 210 and the reinforcing portion 260 is formed a welding bonding layer 270 to melt-bond the frame 210 and the reinforcing portion 260. The welding bonding layer 270 may be formed by welding through fusion or pressure welding.

For example, the frame 210 and the reinforcement part 260 may be coupled by heating and melting metal materials on the coupling surfaces of the frame 210 and the reinforcement part 260 to rearrange their atomic bonds. Alternatively, the frame 210 and the reinforcement part 260 may be coupled by applying physical pressure or ultrasonic vibration to the coupling surface.

According to the above structure, the reinforcement part 260 is connected to the boss 250, and is inserted into the through hole 211 formed in the frame 210 to form the through hole 211 during external impact. Since it is made to hang on, the boss 250 can be supported and reinforced.

That is, in the structure where the boss is seated on one surface of the frame, which is a conventional structure, and the joining surface is welded, the external impact amount is concentrated on the joining surface, but not only the welding layer 270 but also the through hole 211 under the structure. The inner wall 212 of the frame 210 forming the) is made to absorb the impact amount. Therefore, since the impact amount is dispersed compared to the existing structure, the boss 250 can be reinforced.

In addition, since the boss reinforcement structure is provided, the mobile terminal 100 having improved durability against external impact may be provided.

7 and 8 are exploded perspective and sectional views showing another embodiment of the boss reinforcement structure shown in FIG. 4, respectively.

7 and 8, a through hole 311 is formed in the frame 310. The inner wall 312 of the frame 310 forming the through hole 311 is made so that the engaging pin 360, which is inserted to reinforce the boss 350 can be caught during an external impact.

The boss 350 is disposed on one surface of the frame 310 and is formed to protrude to penetrate the printed circuit board 320. The boss 350 has a hollow shape sharing the central axis with the through hole 311. The boss 350 may be, for example, a hollow cylinder having an inner diameter such as the through hole 311.

The boss 350 is configured to couple the frame 310 and another frame (for example, the rear case 102 shown in FIG. 4) to be coupled to the frame 310, and to connect the printed circuit board 320. It is formed to support. For example, the outer circumferential surface of the boss 350 may be in surface contact with the side surface of the printed circuit board 320 during an external impact, thereby supporting the printed circuit board 320 and limiting movement.

The reinforcing part may be a coupling pin 360 formed to protrude to be inserted into the boss 350 through the through hole 311. Coupling pin 360 includes an insertion portion 361 and the support 362.

The insertion part 361 is formed to protrude so as to be inserted into the boss 350, and is configured to reinforce the boss 350 with respect to the shear direction force applied to the boss 350. One end of the insertion part 361 may be formed to protrude more than one surface of the printed circuit board 320 when the insertion part 361 is inserted into the boss 350. According to the above structure, since the insertion part 361 supports all the force in the shear direction applied to the boss 350 by the printed circuit board 320 during an external impact, the boss 350 may be more reinforced.

The support part 362 is formed to surround the outer circumferential surface of the insertion part 361, and is disposed to cover the other surface of the frame 310.

Between the frame 310 and the boss 350, and between the frame 310 and the support 362, a weld bonding layer 370 for melting and bonding them, respectively, is formed. The welding bonding layer 370 may be formed by welding through the fusion welding or the above-described welding method.

According to the structure, the coupling pin 360 is connected to the boss 350, the inner wall 312 is inserted into the through hole 311 formed in the frame 310 to form a through hole 311 during an external impact Since it is made to hang on, the boss 350 can be supported and reinforced.

In addition, since the boss reinforcement structure is provided, the mobile terminal 100 having improved durability against external impact may be provided.

The reinforcement structure of the boss described above and the mobile terminal having the same are not limited to the configuration and method of the above-described embodiments, and the above embodiments may be selectively combined with all or some of the embodiments so that various modifications may be made. It may be configured.
