Abstract

A bracket is used for retaining an expansion card. The expansion card includes a printed circuit board (PCB) and a slot cover attached to the PCB. The bracket includes a back wall, a retaining wall, and a retainer. The back wall defines at least one expansion slot corresponding to the slot cover. The retaining wall is opposite to the sidewall. The retainer is attached to the retaining wall. The retainer includes an elongated body, a first retaining wall, and a second retaining wall substantially parallel to the first retaining wall. A sliding channel is defined between the first retaining wall and the second retaining wall. An edge of the PCB is capable of being slid and retained in the sliding channel.

Claims

1. A bracket for retaining an expansion card comprising a printed circuit board (PCB) and a slot cover attached to the PCB, the bracket comprising:

a back wall, the back wall defining at least one expansion slot corresponding to the slot cover; and

a retaining wall opposite to the sidewall; and

a retainer attached to the retaining wall, the retainer comprising an elongated body, a first retaining wall, and a second retaining wall substantially paralleled to the first retaining wall, a sliding channel defined between the first retaining wall and the second retaining wall;

wherein an edge of the PCB is capable of being slid and retained in the sliding channel.

2. The bracket of claim 1, wherein an oblique guide portion is formed on the first retaining wall for facilitating guiding the edge of the PCB.

3. The bracket of claim 1, wherein the retainer further comprises a resilient securing portion for movably retaining the PCB.

4. The bracket of claim 3, wherein the securing portion comprises a resilient arm extending from the second retaining wall and a protrusion protrudes from the arm for blocking the PCB.

5. The bracket of claim 4, wherein the protrusion comprises an oblique surface opposite to the sliding channel.

6. The bracket of claim 4, wherein the protrusion comprises an L-shaped securing surface for retaining the PCB.

7. The bracket of claim 4, wherein the securing portion further comprises a tab at a distal end of the arm.

8. The bracket of claim 1, wherein the retaining wall defines at least one through hole, and the retainer comprises at least one post corresponding to the at least one through hole.

9. The bracket of claim 8, wherein each post is divided into two resilient parts, a slit is defined between the two resilient parts.

10. The bracket of claim 8, wherein each resilient part comprises a neck portion and a head portion.

11. An electronic device comprising:

an expansion card comprising a printed circuit board (PCB) and a slot cover attached to the PCB;

a bracket for securing the expansion card, the bracket comprising;

a back wall, the back wall defining at least one expansion slot corresponding to the slot cover; and

a retaining wall opposite to the sidewall; and

a retainer attached to the retaining wall, the retainer comprising an elongated body, a first retaining wall, and a second retaining wall substantially parallel to the first retaining wall, a sliding channel defined between the first retaining wall and the second retaining wall;

wherein an edge of the PCB is capable of being slid and retained in the sliding channel.

12. The electronic device of claim 11, wherein an oblique guide portion is formed on the first retaining wall for facilitating guiding the edge of the PCB.

13. The electronic device of claim 11, wherein the retainer further comprises a resilient securing portion for movably retaining the PCB.

14. The electronic device of claim 13, wherein the securing portion comprises a resilient arm extending from the second retaining wall and a protrusion protrudes from the arm for blocking the PCB.

15. The electronic device of claim 14, wherein the protrusion comprises an oblique surface opposite to the sliding channel.

16. The electronic device of claim 14, wherein the protrusion comprises an L-shaped securing surface for retaining the PCB.

17. The electronic device of claim 14, wherein the securing portion further comprises a tab at a distal end of the arm.

18. The electronic device of claim 11, wherein the retaining wall defines at least one through hole, and the retainer comprises at least one post corresponding to the at least one through hole.

19. The electronic device of claim 18, wherein each post is divided into two resilient parts, a slit is defined between the two resilient parts.

20. The electronic device of claim 18, wherein each resilient part comprises a neck portion and a head portion.
