## Title
Mounting apparatus for expansion card

## Abstract

A mounting apparatus for an expansion card with a blocking piece is disclosed. The mounting apparatus includes a mounting bracket and a fixing piece. The mounting bracket includes a support plate with two bent portions. The fixing piece is pivotably mounted on the mounting bracket. The fixing piece includes a resisting piece, two resilient pressing pieces, and an engaging portion. The resisting piece secures the blocking piece to the support plate. The two resilient pressing pieces are connected to the resisting piece. The engaging portion retains the fixing piece to the mounting bracket. A pivot portion protrudes from each pressing piece and is received in each bent portion. The two pressing pieces are oppositely pressed to disengage the pivot portion from the bent portion.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to mounting apparatus, and particularly to a mounting apparatus for securing an expansion card.
2. Description of Related Art
Nowadays, most computer systems or other electronic devices employ a plurality of circuit cards, such as expansion cards and adapters. These cards are typically mounted to a computer motherboard in a perpendicular fashion relative to the computer motherboard. In particular, the cards are usually inserted into edge card connectors, which are mounted on the computer motherboard. However, merely inserting a card into an edge connector is insufficient to securely maintain the card within the computer chassis. A card connected in this fashion could easily disconnect from the edge connector, which may prevent, or significantly inhibit, acceptable operation of the computer. Accordingly, additional structure is normally required to secure a card within a computer chassis. A conventional manner of securing a card within a computer chassis is to provide a card bracket fastened to the computer chassis with a removable screw. However, a significant disadvantage of a screw-secured bracket is that the screw can be inadvertently dropped into the computer chassis during installation and removal of the bracket.

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 FIG. 1, a mounting apparatus is used for mounting an expansion card 50. The expansion card 50 is secured to a blocking piece 52. The mounting apparatus in accordance with an embodiment includes a mounting bracket 10, and a fixing piece 30 pivotably mounted to the mounting bracket 10.
The mounting bracket 10 includes a base plate 12 and a support plate 14 bent from the base plate 12. The support plate 14 is perpendicular to the base plate 12. A mounting opening 122 is defined in the base plate 12 adjacent to the support plate 14. A fixing flange 124 is formed on the base plate 12 adjacent to the mounting opening 122. Two C-shaped bent portions 142 are bent from a distal end of the support plate 14 at intervals.
Referring to FIG. 2, FIG. 3 and FIG. 4, the fixing piece 30 includes two resilient pressing pieces 36, a resisting piece 32, an extension portion 34 perpendicular to the resisting piece 32, and an engaging portion 38. A distal end of the resisting piece 32 is bent to form a flange 324 and a connecting piece 326. The two pressing pieces 36 extend from two edges of the connecting piece 326 respectively. A U-shaped configuration is formed by the resisting piece 32, the flange 324, and the connecting piece 326. An angle between each pressing piece 36 and the connecting piece 326 may exceed 90 degrees. A pivot portion 362 protrudes from each pressing portion 36 and is received in each bent portion 142. Each pivot portion 362 is a hollow cylindrical flange. A pressing portion 364 extends from each pressing piece 36 positioned away from the connecting piece 362. A round protrusion 322 protrudes from the resisting piece 32 facing the support plate 12 to resist against the blocking piece 52. Two resilient connecting portions 342 are formed from the extension portion 34 to connect to the engaging portion 38. Two extension flanges 346 extend from a distal end of the extension portion 34. The engaging portion 38 includes an engaging connection portion 382 connecting to the connecting portion 342. An arcuate engaging flange 384 and an operating portion 386 connects to the engaging flange 384.
Referring to FIG. 5, in assembly, the two pressing portions 364 are pressed inward. The two pressing pieces 36 are deformed. The two pivot portions 362 are received in the two bent portions 142. The two pressing pieces 36 are released. The pressing pieces 36 rebound to engage the corresponding bent portion 142. The fixing piece 30 is pivotably mounted to the mounting bracket 10.
Referring to FIG. 6, in use, the expansion card 50 is mounted on the mounting bracket 10. The blocking piece 52 is located between the support plate 14 and the resisting piece 32. When the fixing piece 30 is rotated, the fixing flange 124 is engaged between the engaging flange 384 and the extension flange 346. The protrusion 322 resists against the blocking piece 52. The expansion card 50 is fixed on the mounting bracket 10. The operating portion 386 is pressed toward the extension portion 34. The engaging flange 384 is disengaged from the fixing flange 124. The protrusion 322 disengages from the blocking piece 52 so that the expansion card 50 is unlocked.
In disassembly, the pressing portion 364 is pressed. The pressing piece 36 disengages from the bent portion 142 to unlock the fixing piece 30. In one embodiment, the pressing piece 36 is located on the resisting piece 32 to complete the same functions.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of 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.
