Abstract

A computer enclosure includes a bottom surface, a sidewall connected to the bottom surface, and a cover. A flange is located on a top edge of the sidewall. A plurality of elastic fingers is formed on the flange. Each of the plurality of elastic fingers includes a free end from which a contact point protrudes. The cover covers the flange. The elastic fingers are elastically pressed by the cover, and the contact point contacts the cover.

Claims

1. A computer enclosure, comprising:

a bottom surface;

a sidewall connected to the bottom surface, a flange extending toward the center of the enclosure from a top edge of the sidewall, a free edge of the flange forming an edge roll by bending the flange downwards, a plurality of elastic fingers formed on the flange, wherein each of plurality of the elastic fingers comprises a fixed end connected to the edge roll, a free end reversely extending from the fixed end toward the sidewall, and a contact point protruding from the free end, the fixed end and the free end being both elastically deformable; and

a cover covering the flange and elastically pressing the plurality of elastic fingers, the contact point contacting the cover.

2. The computer enclosure of claim 1, wherein the free end of each of the plurality of elastic fingers is set at an angle with respect to a plane defined by the flange.

3. The computer enclosure of claim 1, wherein a portion of each of the plurality of elastic fingers, on which the free end is formed, extends in a direction towards the sidewall.

4. The computer enclosure of claim 3, wherein each of the plurality of elastic fingers is “

J”

-shape.

5. The computer enclosure of claim 1, wherein the flange defines a slot around each of the plurality of elastic fingers.

6. The computer enclosure of claim 5, wherein the slot surrounds three sides of each of the plurality of elastic fingers.

7. The computer enclosure of claim 5, wherein a width of the slot is 2 mm to 3.5 mm, and a width of each of the plurality of elastic fingers is 3 mm to 4 mm.

8. The computer enclosure of claim 7, wherein a width of the slot is about 2.5 mm, and a width of each of the plurality of elastic fingers is about 3.2 mm.

9. A computer enclosure, comprising:

a sidewall comprising a flange extending toward the center of the enclosure from a top edge of the sidewall a free edge of the flange forming, an edge roll by bending the flange downwards, at least one elastic finger formed on the edge roll;

the at least one elastic finger comprises a fixed end connected to the edge roll and a free end reversely extending from the fixed end toward the sidewall, a portion of the at least one elastic finger, on which the free end is formed, extends in a direction towards the sidewall, and the fixed end and the free end are both elastically deformable.

10. The computer enclosure of claim 9, wherein the at least one elastic finger is “

J”

shape.

11. The computer enclosure of claim 10, wherein the flange defines a slot around the at least one elastic finger.

12. The computer enclosure of claim 11, wherein the free end of the at least one elastic finger is set at an angle with respect to a plane defined by the flange.

13. The computer enclosure of claim 12, wherein a contact point protrudes from the free end of the at least one elastic finger, a cover is located on the flange, the at least one elastic finger is pressed by the cover, and the contact point contacts the cover.

14. The computer enclosure of claim 11, wherein the slot is “

U”

-shaped, and surrounds three sides of the at least one elastic finger.
