## Title
Electronic device with a resilient bracket

## Abstract

An electronic device includes a chassis and a bracket. An opening is defined in the chassis. The opening has a first side edge and a second side edge located at opposite sides thereof. A length of the second side edge is greater than that of the first side edge. The bracket is mounted in the opening. The bracket includes a pair of first hooks and a pair of second hooks at opposite sides thereof. A distance between the pair of first hooks corresponds to the length of the first side edge. A distance between the pair of second hooks corresponds to the length of the second side edge. The pair of first hooks is engaged into the opening along the first side edge. The pair of second hooks is engaged into the opening along the second side edge.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to an electronic device with a power switch module.
2. Description of Related Art
Computers usually include a chassis and a power switch module attached to the chassis. The power switch module includes a bracket, a switch member held by the bracket, and a light emitting diode (LED) held by the bracket. The switch member is configured to allow users to power on or off the computer. The LED is configured to indicate an on/off state of the computer. An opening is defined in the chassis for mounting the bracket. The bracket includes a pair of hooks disposed at opposite sides. The pair of hooks engages with opposite side edges of the opening for securing the bracket. However, the pair of hooks is often symmetrical which cause the bracket to be easily mounted in the opening at an incorrect direction opposite to a desired direction.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation. In the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1 and 2, an embodiment of an electronic device includes a chassis 10 and a power switch module 40. The power switch module 40 includes a mounting bracket 20 and a pair of LED lamps 30. The mounting bracket 20 is configured to hold a switch member (not shown) and the pair of LED lamps 30. In one embodiment, the electronic device is a computer.
The chassis 10 includes a front panel 12. An opening 121 is defined in the front panel 12 corresponding to the mounting bracket 20. The opening 121 has a substantially rectangular shape. A distance between left and right side edges of the opening 121 is greater than that between upper and lower edges of the opening 121. The opening 121 has a first side edge 1211 and a second side edge 1212 located at opposite sides thereof. A length of the second side edge 1212 is greater than that of the first side edge 1211. A pair of protruding pieces 123 is defined at a pair of corners of the opening 121 at the first side edge 1211. A pair of block pieces 125 protrudes from upper and lower edges of the opening 121.
Referring to FIG. 3, the mounting bracket 20 includes a top plate 22, a base plate 24 parallel to the top plate 22, a first side wall 26, and a second side wall 28 parallel to the first side wall 26. The first side wall 26 and the second side wall 28 are located between the top plate 22 and the base plate 24. A distance between the top plate 22 and the base plate 24 is less than the distance between the first side wall 26 and the second side wall 28. The distance between the first side wall 26 and the second side wall 28 is substantially equal to the length of the opening 121. A pair of first resilient arms 261 extends from the first side wall 26. A first hook 263 protrudes from a distal end of each of the pair of first resilient arms 261. A pair of second resilient arms 281 extends from the second side wall 28. A second hook 283 protrudes from a distal end of each of the pair of second resilient arms 281. A distance between the pair of second resilient arms 281 is greater than that between the pair of first resilient arms 261. A first mounting slot 23 and a second mounting slot 25 are defined in the mounting bracket 20 for mounting the pair of LED lamps 30 (see FIG. 1). The first mounting slot 23 and the second mounting slot 25 are adjacent to a pair of diagonal corners of the mounting bracket 20.
Referring to FIGS. 4 and 5, in assembly, the pair of LED lamps 30 are mounted in the first mounting slot 23 and the second mounting slot 25. The pair of first resilient arms 261 extends into the opening 121 along the first side edge 1211 of the opening 121. The first hooks 263 clamp an interior surface of the front panel 12 for preventing the mounting bracket 20 from moving outward from the opening 121. The pair of second resilient arms 281 extends into the opening 121 along the second side edge 1212 of the opening 121. The second hooks 283 clamp the interior surface of the front panel 12 for preventing the mounting bracket 20 from moving outward from the opening 121. The top plate 22 and the base plate 24 abut outer surfaces of the pair of block pieces 125. The pair of first resilient arms 261 is located between the pair of protruding pieces 123 and abuts the pair of protruding pieces 123. The pair of second resilient arms 281 abuts the upper and lower edges of the opening 121. Thus, the mounting bracket 20 cannot move upwards or downwards. Then the power switch module 40 is secured to the chassis 10.
The mounting bracket 20 can be only mounted into the opening 121 at a single desired position where the pair of first resilient arms 261 aligns with the first side edge 1211 of the opening 121 and the pair of second resilient arms 281 aligns with the second side edge 1212 of the opening 121. Thus, the electronic device of the present disclosure utilizes the above described structure to prevent incorrect insertion of the mounting bracket 20.
While the present disclosure has been illustrated by the description of preferred embodiments thereof, and while the preferred embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such details. Additional advantages and modifications within the spirit and scope of the present disclosure will readily appear to those skilled in the art. Therefore, the present disclosure is not limited to the specific details and illustrative examples shown and described.
