Abstract

The present invention relates to a mobile terminal and a method of fabricating the same. The mobile terminal includes a frame made of a metal and provided within a terminal body, a printed circuit board spaced apart from one surface of the frame and having various electronic components mounted thereon, and a shield can disposed on the printed circuit board in a manner of facing the frame, and capable of shielding electromagnetic waves by covering the electronic components, wherein the shield can is provided with a ground unit that is formed at at least one region and protruding toward the frame so as to be electrically connected to the frame.

Claims

1. A mobile terminal comprising:

a frame made of a metal and provided within a terminal body;

a printed circuit board spaced apart from one surface of the frame and having various electronic components mounted thereon; and

a shield can disposed on the printed circuit board in a manner of facing the frame, and capable of shielding electromagnetic waves by covering the electronic components,

wherein the shield can is provided with a ground unit that is formed at at least one region and protruding toward the frame so as to be electrically connected to the frame.

2. The terminal of claim 1, wherein the ground unit comprises:

a contact portion brought into surface-contact with the frame; and

a connecting portion connecting the shield can the contact portion to each other.

3. The terminal of claim 2, wherein the connecting portion is provided by at least one, the connecting portion extending from a main surface portion of the shield can.

4. The terminal of claim 3, wherein through holes are formed between the ground unit and the main surface portion.

5. The terminal of claim 4, wherein the contact portion is formed parallel to the main surface portion.

6. The terminal of claim 2, wherein the connecting portion is inclined from the main surface portion toward the contact portion.

7. The terminal of claim 1, wherein the terminal body comprises:

a front case supporting a display unit;

a rear case provided beneath the front case to limit an installation space of a plurality of components along with the front case; and

a rear cover covering a rear surface of the rear case,

wherein the frame is integrally formed with the front case.

8. The terminal of claim 2, wherein the connecting portion is symmetric based on a center of the contact portion.

9. The terminal of claim 2, wherein the contact portion is formed in a polygonal, circular or oval shape, or in combination thereof.

10. The terminal of claim 9, wherein the connecting portion is formed at each of edges or vertices of the polygon when the contact portion has the polygonal shape.

11. The terminal of claim 9, wherein each of the connecting portions is formed to have the same angle from a center of the circle or oval when the contact portion has the circular or oval shape.

12. A method for fabricating a mobile terminal, which comprises a frame made of a metal, a printed circuit board spaced apart from one surface of the frame and having various electronic components mounted thereon, and a shield can disposed on the printed circuit board and having a flat main surface portion, the method comprising:

forming a plurality of through holes at the shield can to form a contact portion having a predetermined area and a connecting portion connecting the contact portion and the shield can;

pressing the contact portion to protrude from the main surface portion; and

coupling the contact portion and the frame in a closely-adhering manner.

13. The method of claim 12, wherein a gap between the frame and the main surface portion is shorter than a gap between the contact portion and the main surface portion, such that the contact portion is elastically brought into contact tightly with the frame.

14. The method of claim 12, wherein the terminal body comprises:

a front case supporting a display unit;

a rear case provided beneath the front case to limit an installation space of a plurality of components along with the front case; and

a rear cover covering a rear surface of the rear case,

wherein the frame is integrally formed with the front case.

15. The method of claim 12, wherein the contact portion is formed in a polygonal, circular or oval shape, or in combination thereof.
