1. Technical Field
The present disclosure relates to electronic devices, especially to an electronic device with a mounting bracket for receiving expansion cards and connectors to the expansion card.
2. Description of Related Art
Expansion cards can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Some expansion cards also need to be connected to a power supply of the computer system. However, the power supply cables for the expansion cards may interfere with other working hardware in the computer.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
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
The chassis 10 includes a bottom wall 11, a first sidewall 13, and a second sidewall 15. The first sidewall 13 and the second sidewall 15 are located on opposite sides of the bottom wall 11. The first sidewall 13 and the second sidewall 15 are substantially perpendicular to the bottom wall 11. The second sidewall 15 defines a plurality of vents 156, at least one locking hole 153, and at least one positioning hole 151.
A plurality of slots 51 is located on the motherboard 50.

The cover portion 21 includes at least one resilient hook 212 and at least one positioning tab 215. The plurality of retaining members 216 is located on a side of the cover portion 21. Each retaining member 216 is U-shaped. Each of the plurality of retaining members 216 includes a retaining wall 2165 and two substantially parallel locating walls 2161 substantially perpendicular to the retaining wall 2165. A retaining hole 2166 is defined in the retaining wall 2165 of each of the plurality of retaining members 216. Each of the locating walls 2161 includes a wide portion 2162 and a narrow portion 2163. A passageway 2168 is defined between the two locating walls 2161 of each of the plurality of retaining members 216. A guiding channel 2167 is defined between the two locating walls 2161 of two adjacent retaining members 216 of the plurality of retaining members 216.
The top portion 23 includes a top wall 231 and a plurality of guiding members 233 oblique to the top wall 231. Each of the plurality of guiding members 233 extends toward each guiding channel 2167 and defines a guiding slot 2331 along an extending direction of each of the plurality of the guiding member 233 for guiding the expansion card 30.
The expansion card 30 includes a body 31, a connector interface 36, a block tab 33, and a mounting tab 35. The block tab 33 and mounting tab 35 are located on opposite sides of the body 31. The connector interface 36 is located on the body 31.

Before installing the expansion card 30, the connector 80 can be mounted to the retaining wall 2165 of one retaining member 216 with the resilient locking portion 83 engaging with the retaining hole 2166 of the retaining member 216.
When the expansion card 30 is mounted to the slot 51 of motherboard 50, the mounting tab 35 can slide along the guiding slot 2331 of the guiding member 233 and slide into the guiding channel 2167. The block tab 33 is mounted to the first sidewall 13. The connector 80 can be removed from the retaining member 216 and is mounted to the expansion card 30 for providing power to the expansion card 30. The receiving space may communicate with the vent 156 and the passageway 2168 of the retaining member 216 for dissipating heat from the expansion card 30 and other heat generating elements inside the chassis 10.
In other embodiments, the guiding member 233 may be resiliently deformed when guiding the mounting tab 35 into the guiding channel 2167 and can block the mounting tab 35 from moving out of the bracket 20 when the expansion card 30 is mounted in the chassis 10.
It is also to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of the embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
