## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting brackets, and particularly to a mounting bracket for mounting a disk drive to a computer enclosure.
2. Description of Related Art
In the enclosure of a typical personal computer, there are generally data storage devices such as CD-ROM drives, floppy disk drives (FDDs) and hard disk drives (HDDs) mounted therein. These data storage devices are generally fixedly received in brackets within an enclosure of the computer.
To fix a data storage device such as a disk drive in an enclosure, a mounting bracket is usually installed in the enclosure first. Then the disk drive is fixed in the mounting bracket. This kind of conventional assembly process is unduly laborious and slow. In mass-production facilities, the assembly process is liable to slow up a production line and lead to inefficiency and increased costs.
To overcome these difficulties, an alternative conventional assembly means comprises: firstly, fixing the disk drive in the mounting bracket to form a mounting bracket assembly; and then installing the mounting bracket assembly in the enclosure.
There are numerous kinds of conventional mounting bracket assemblies. These generally include using a quantity of screws to fix the disk drive in the mounting bracket, or alternatively fixing guiding rails on the disk drive and then slidingly inserting the disk drive into the mounting bracket. However, using a quantity of screws adds to component parts and costs. In addition, fastening or detachment of the screws using a tool is unduly laborious and time-consuming. Similarly, screws are generally needed to fixing the guiding rails on the disk drive. Furthermore, using guiding rails usually creates spaces between the disk drive and the mounting bracket. Electromagnetic radiation is liable to leak out from the mounting bracket and generate a lot of static electricity in the enclosure.
Examples of conventional data storage device fastening structures are found in Taiwan Patent Application Nos. 82202204 and 83202927.
An improved mounting bracket which overcomes the above-mentioned problems is desired.
BRIEF SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a mounting bracket that can conveniently receive data storage devices therein.
Another object of the present invention is to provide a mounting bracket that has good grounding.
To achieve the above-mentioned objects, a mounting bracket for holding a disk drive includes a bottom wall, a first sidewall extending upwardly from a border of the bottom wall with two locating pins protruding inwardly therefrom corresponding to two fixing holes defined in a sidewall of the disk drive, a second sidewall extending upwardly from an opposite border of said bottom wall for sandwiching the disk drive with the first sidewall, and locking means for engaging with a second sidewall of the disk drive to retain the disk drive in the mounting bracket. In assembly, the disk drive is placed in the mounting bracket, and the locating pines are inserted into the fixing holes of the disk drive. With the other sidewall of the disk drive secured to the fixing structures of the mounting bracket, the disk drive is secured in the mounting bracket.

A second sidewall (not labeled) extends perpendicularly from an opposite edge of the bottom wall 12. The second sidewall comprises a first vertical wall 18, a horizontal connecting wall 20, and a second vertical wall 22. Two generally triangular protrusions 24 protrude inwardly from the second vertical wall 22.
A first sidewall (not visible) of the disk drive 30 defines two fixing holes (not visible) corresponding to the locating pins 16 of the mounting bracket 10. A second sidewall (not labeled) of the disk drive 30 comprises a recessed lower first wall 36, and a protruding upper second wall 38. The first wall 36 of the disk drive 30 defines two fixing holes (not visible) therein, and reference is made to the alternative embodiment of the invention described below in this regard.
Referring also to FIG. 3, in assembly, the disk drive 30 is placed in the mounting bracket 10, and the locating pins 16 of the mounting bracket 10 are inserted into the fixing holes of the disk drive 30. A top of the disk drive 30 near the second sidewall is pressed until the second wall 38 of the disk drive 30 rides over and is engaged under the protrusions 24 of the second vertical wall 22. In this position, the first wall 36 abuts the first vertical wall 18. Thus, the disk drive 30 is securely received in the mounting bracket 10. Electromagnetic radiation is not liable to leak out from the mounting bracket 10 since the first sidewall of the disk drive 30 abuts the first sidewall 14 of the mounting bracket 10, the first wall 36 of the disk drive 30 abuts the first vertical wall 18 of the mounting bracket 10, and the second wall 38 of the disk drive 30 abuts the second vertical wall 22 of the mounting bracket 10.
