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. 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, a second retaining wall, and a resilient securing portion;

the first retaining wall and the second retaining wall are substantially parallel to the first retaining wall, a sliding channel defined between the first retaining wall and the second retaining wall, the securing portion comprising a resilient arm, extending from the second retaining wall, and a protrusion protruding from the resilient arm for blocking the PCB;

wherein the resilient arm is pressed from an original state by the PCB when the PCB is sliding into the sliding channel and rebounds back to the original state when the PCB is retained in the sliding channel.

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

3. The electronic device of claim 1, wherein the protrusion comprises an oblique surface opposite to the sliding channel.

4. The electronic device of claim 1, wherein the protrusion comprises an L-shaped securing surface for retaining the PCB.

5. The electronic device of claim 1, wherein the securing portion further comprises a tab at a distal end of the arm.

6. The electronic device 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.

7. The electronic device of claim 6, wherein each post is divided into two resilient parts, a slit is defined between the two resilient parts.

8. The electronic device of claim 6, wherein each resilient part comprises a neck portion and a head portion.
