Shield can and method for fabricating the same

1. A shield can, comprising:

a frame having a hole, two first cutouts, and two second cutouts defined in a top wall of the frame, the first cutouts and the second cutouts communicating with the hole;

a planar enclosure attached to the frame and covering the hole;

wherein the frame and the planar enclosure are formed by punching a metallic piece, the top wall includes a first flange and an opposite second flange, the first flange defines the two first cutouts formed during the punching of the metallic piece and facing the second flange, the second flange defines the two second cutouts formed during the punching of the metallic piece and facing the first flange, the distance between the two first cutouts is different from the two second cutouts;

the planar enclosure includes a main plate portion, two first protrusions formed during the punching of the metallic piece and two second protrusions formed during the punching of the metallic piece protruding from two opposing sides of the main plate portion respectively, the main plate portion corresponds to the hole in shape and size, each of the two first protrusions having the same structure, the each of the two first protrusions corresponds to each of the two first cutouts in shape and size, each of the two second protrusions having the same structure, and the each of the two second protrusions corresponds to each of the two second cutouts in shape and size; and

the planar enclosure is fixed to the top wall with the first protrusions abutting with the upper surface of the second flange and the second protrusions abutting with the upper surface of the first flange.

2. The shield can as claimed in claim 1 , wherein the main plate portion defines at least one prying hole and a plurality of circular holes therein, the at least one prying hole is used to disassemble the planar enclosure from the frame, the plurality of circular holes are used to disperse heat.

3. The shield can as claimed in claim 1 , wherein the frame includes a plurality of sidewalls extending downwardly from a perimeter flange of the top wall, each sidewall of the plurality of sidewalls defines a plurality of latching holes.

4. A method for fabricating a shield can, comprising:

providing a metallic piece;

punching the metallic piece into at least two pieces forming a frame having a top wall and a planar enclosure having a main plate portion and protrusions, each of the protrusions having the same structure, the frame defining a hole corresponding to the main plate portion in shape and size and a plurality of cutouts, each of the plurality of cutouts corresponding to the each of the protrusions in shape and size, the each of the cutouts communicating with the hole; and

attaching the planar to the frame by fixing the protrusions to an upper surface of the top wall, whereby the main plate portion covering the hole.

5. The method for fabricating a shield can as claimed in claim 4 , wherein the top wall includes a first flange and an opposite second flange, the first flange defines two first cutouts of the plurality of cutouts facing the second flange, the second flange defines two second cutouts of the plurality of cutouts facing the first flange, the distance between the two first cutouts is different from the distance between the two second cutouts.

6. The method for fabricating a shield can as claimed in claim 5 , wherein the protrusions of the planar enclosure includes two first protrusions and two second protrusions, the first protrusions protrudes from a side of the main plate portion, the two second protrusions protrudes from an opposite side of the main plate portion, each of the two first protrusions corresponds to each of the two first cutouts in shape and size, and each of the two second protrusions corresponds to each of the two second cutouts in shape and size.

7. The method for fabricating a shield can as claimed in claim 6 , wherein the each of the first protrusions are fixed to the upper surface of the second flange by soldering, and the each of the second protrusions are fixed to the upper surface of the first flange by soldering.

8. The method for fabricating a shield can as claimed in claim 7 , wherein the each of the first protrusions are defined by the each of the first cutouts of the frame, and the each of the second protrusions are defined by the each of the second cutouts of the frame.

9. The method for fabricating a shield can as claimed in claim 7 , wherein the main plate portion defines at least one prying hole and a plurality of circular holes therein, the at least one prying hole is used to disassemble the planar enclosure from the frame, the plurality of circular holes are used to disperse heat.
