## Background
BACKGROUND
1. Field of the Invention
The present invention relates to mounting assembly for shielding apparatuses, and more particularly to a mounting assembly for shielding apparatus of a data storage device.
2. Description of Related Art
In a computer or a server, a disk drive, such as a hard disk drive, and/or a shielding apparatus is usually provided. In order to secure the disk drive or the shielding apparatus to the disk drive or the server, a mounting assembly is needed.
For example, a mounting assembly includes a drive bracket, a tray for receiving the shielding apparatus, and a securing structure installed thereon for securing the tray in the drive bracket. In assembly, the shielding apparatus is firstly received in the tray. Then the shielding apparatus and the tray are together inserted into the drive bracket, and then secured in the drive bracket by operating the securing structure. In removal, the securing structure is operated to release the tray from the drive bracket. The tray and the shielding apparatus are thereby drawn out from the drive bracket. The shielding apparatus can be thus removed from the tray. Which altogether is a complicated laborious operation.
What is needed, therefore, is a mounting assembly for conveniently replacing or maintaining a shielding apparatus in a disk drive or a server.
SUMMARY
A mounting assembly for shielding EMI, the mounting assembly includes a drive bracket and a shielding apparatus. The drive bracket includes a bottom wall, a first retaining wall, a second retaining wall, and a dividing wall between the first retaining wall and the second retaining wall. The first retaining wall defines a first hole, the second retaining wall defines a second hole. The dividing wall defines an upper hole and a lower hole, which is the same size as the upper hole. The distance between the upper hole and the bottom wall is substantially equal to the distance between the first hole and the bottom wall, the distance between the lower hole and the bottom wall is substantially equal to the distance between the second hole and the bottom wall, and the lower hole is below the upper hole. The shielding apparatus is received in the drive bracket, and includes a shielding cover and a bezel mounted on a front side of the shielding cover. The shielding cover has a first flange and a second flange respectively extending from two opposite side edges thereof. The first flange has a protuberance engaged in the first hole of the first retaining wall, and the second flange has a protuberance engaged in the lower hole of the dividing wall.
Other advantages and novel features of the present invention will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION
Referring to FIG. 1, a mounting assembly for a shielding apparatus 30 in accordance with a preferred embodiment of the present invention includes the shielding apparatus 30 which is for shielding EMI (Electro Magnetic Interference), and a drive bracket 10 configured for receiving the shielding apparatus 30.
The shielding apparatus 30 includes a shielding cover 31 and a bezel 33 which is mounted on a front side of the shielding cover 31. A first flange 36 and a second flange 38 are respectively perpendicularly extending from two opposite side edges of the shielding cover 31. The drive bracket 10 includes a bottom wall 13, a dividing wall 15, a first retaining wall 16, and a second retaining wall 18 perpendicularly extending up from the bottom wall 13, and a top wall 11 covering the first retaining wall 16, the second retaining wall 18, and the dividing wall 15. The bottom wall 13, the first retaining wall 16, the second retaining wall 18, and the top wall 11 cooperatively enclose a casing space. The casing space is divided into two receiving spaces 17 for installing two shielding apparatuses. The first retaining wall 16 defines a first hole 161, and the second retaining wall 18 defines a second hole 181. The dividing wall 15 defines a fixing hole, which has an upper hole 153 and a lower hole 151 the same size as the upper hole 153. The distance between the upper hole 153 and the bottom wall 13 is substantially equal to the distance between the first hole 161 and the bottom wall 13. The distance between the lower hole 151 and the bottom wall 13 is substantially equal to the distance between the second hole 181 and the bottom wall 13. The lower hole 151 is below the upper hole 153 and communicates with the upper hole 153 via a narrower connecting slot 152 (see FIG. 2). A size of the first hole 161 of the first flange 16 is substantially equal to that of the upper hole 153 of the dividing wall 15. A line connecting the center of the upper hole 153 and the center of the lower hole 151 is perpendicular to the top wall 11. The first flange 36 of the shielding cover 31 defines a protuberance 361, which is engagable in the first hole 161 of the first retaining wall 16. The second flange 38 of the shielding cover 31 defines a protuberance 381, which is engagable in the lower hole 151 of the dividing wall 15. The mounting assembly can advantageously further include a second shielding apparatus 40, same as the shielding apparatus 30 (referring to FIG. 4). The second shielding apparatus 40 engages in the upper hole 153 of the dividing wall 15 and the second hole 181 of the second retaining wall 18.
Referring to FIG. 3 and FIG. 4, when assembling the shielding apparatus 30, the bezel 33 is mounted on the front end of the shielding cover 31 to form the shielding apparatus 30. The shielding cover 31 faces the receiving space 17. The shielding apparatus 30 is moved towards the drive bracket 10. The first flange 36 and the second flange 38 respectively abut against the first retaining wall 16 and the dividing wall 15 causing the first flange 36 and the second flange 38 to deform inwardly until the protuberance 361 of the first flange 36 and the protuberance 381 of the second flange 38 engage in the first hole 161 and the lower hole 151 respectively, at which point the first flange 36 and the second flange 38 rebound and clamps therein. Thus the shielding apparatus 30 is received in the receiving space 17 and securely mounted to the drive bracket 10, and the same steps are repeated for optionally installing the remaining second shielding apparatus 40. When replacing one of the shielding apparatuses, the shielding apparatus 30 can be removed by pulling the bezel 33.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set fourth in the foregoing description, together with details of the structure and function of the invention, 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
