## Background
BACKGROUND
1. Technical Field
The present disclosure relates to device mounting, and particularly, to an expansion card mounting apparatus for an electronic device.
2. Description of Related Art
Computer systems typically require or include expansion cards providing additional or extended functionality. A frequently used expansion card includes a main body electrically connectable with a motherboard in a computer system, and a generally L-shaped block plate installable on a rear plate of the computer system. The block plate is typically installed on the rear plate by a screw. However, if the screw is not properly fastened, the expansion card easy dislodges or misaligns in the case such that a distal end of the expansion card may experience damaging impact.
Therefore, a mounting apparatus is desired to overcome the limitations described.

An L-shaped first stop portion 254 extends from the main plate 23 and is positioned below the opening 25. The four pivot plates 26 are separated by a distance and positioned between the pair of second block plates 24, corresponding to the opening 25. Each of the four pivot plates 26 includes a first pivot hole 262 defined therein. The two bridge clips 27 are positioned between the pair of second block plates 24. One of the bridge clips 27 is positioned on a right side of the opening 25, between two pivot plates 26. The other of the bridge clips 27 is positioned on a left side of the opening 25, between the other two pivot plates 26. Each of the tabs 28 includes a notch 282 defined therein.
Referring to FIG. 2, the latching member 30 includes a plurality of parallel drive plates 32, a connection plate 34 fixed to the drive plates 32, and a plurality of latching portions 36 fixed to a bottom of the latching member 30. In the illustrated embodiment, the plurality of parallel drive plates 32 is shown as four parallel triangular drive plates, and the plurality of latching portions 36 is shown as four latching portions. The drive plates 32 are separated from each other by a distance. Each of the drive plates 32 includes a bevel edge 322, a first straight edge 324, and a second straight edge 326. An included angle between the bevel edge 322 and the first straight edge 324 defines a second pivot hole 327 therein. Each of the drive plates 32 includes a rail 328 defined therein. The rail 328 is positioned close to the bevel edge 322, and substantially parallel to the bevel edge 322. The connection plate 34 connects with the first straight edge 324 of each of the drive plates 32. The latching portions 36 are parallel to the second straight edge 326. A front end of each of the latching portions 36 is L-shaped.
The operation member 40 includes a plurality of pins 42 each fixed to a bottom of the operation member 40 corresponding to the rail 328 of each of the drive plates 32, two block portions 43 extending from two opposite sides of the operation member 40 respectively, a handle 44 extending from a top end of the operation member 40, a resilient portion 45 parallel to the handle 44, a second stop portion 46 extending at an angle from a bottom end of the operation member 40, and two clip blocks 47 respectively positioned close to the two block portions 43 corresponding to the two bridge clips 27. In the illustrated embodiment, the plurality of pins 42 is shown as four pins. The resilient portion 45 includes a latch block 452 fixed on a side thereof away from the handle 44, and an anti-skid bumper 454 fixed thereon and positioned above the latch block 452.
Each of the two connection members 50 is L-shaped and includes a first post 52, and a second post 54. The second post 54 includes a raised block 542 fixed on an outer side thereof and positioned close to a curved portion of each of the two connection members 50.
Referring to FIG. 3, in assembly of the latching member 30 to the rear panel 20, the latching member 30 is received between the pair of second block plates 24, the second pivot hole 327 of each of the drive plates 32 is aligned with the first pivot hole 262 of each of the pivot plates 26. The latching member 30 and the rear panel 20 can be secured to each other by the second post 54 of each of the two connection members 50 passing through the through hole of each of the pair of second block plates 24, the second pivot hole 327, and the first pivot hole 262. The first post 52 of each of the two connection members 50 is received in the notch 282 of each of the tabs 28 to retain the two connection members 50 in the rear panel 20. The raised block 542 of the second post 54 abuts each of the pair of second block plates 24 to limit passage of the second post 54 through the through hole of each of the pair of second block plates 24.
In assembly of the operation member 40 to the latching member 30, each of the pins 42 of the operation member 40 is received in the rail 328 of each of the drive plates 32.
Referring to FIGS. 4-7, in mounting the expansion card 100 to the rear panel 20, the operation member 40 is withdrawn from the rear panel 20. Each of the pins 42 of the operation member 40 is slidably received in the rail 328 to rotate the latching member 30 outward until sufficient space is provided for the expansion card 100 and a circuit board (not shown) of an electronic device to be secured to each other. The first block plate 10 of the expansion card 100 abuts one of the card slots 201, and the angled portion 14 of the first block plate 10 abuts the support plate 21.
The operation member 40 is then pushed toward the rear panel 20. Each of the pins 42 of the operation member 40 is slidably received in the rail 328 to rotate the latching member 30 inward until each of the latching portions 36 is received in a gap of the angled portion 14 of the first block plate 10. Accordingly, the latch block 452 of the operation member 40 is received in a lower side of the latch 252 of the rear panel 20, each of the two block portions 43 of the operation member 40 is received in an inner side of the restrictor plate 242 of the rear panel 20, the second stop portion 46 is received in an inner side of the first stop portion 254, and the two clip blocks 47 snugly abut the two bridge clips 27 respectively.
During removal of the expansion card 100, the resilient portion 45 is operated to deform the operation member 40 to disengage the latch block 452 from the latch 252 of the rear panel 20. Then the operation member 40 is withdrawn from the rear panel 20. Thus the expansion card 100 can be removed from the circuit board.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
