## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting apparatuses for power supplies, and particularly to a mounting apparatus for readily and securely attaching a power supply to a computer chassis.
2. Description of the Related Art
Generally speaking, a power supply is necessarily to be assembled in a computer enclosure. The power supply is often directly attached to a rear panel of the computer enclosure by a plurality of screws. However, this requires extra tools such as screwdrivers in assembly or disassembly, which is unduly laborious and time-consuming. Additionally, this requires a long assembly line, which lowers assembly efficiency. Furthermore, an unworkable work site will lead to paralysis of the whole assembly line.
Another conventional mounting way is to assemble a power supply to a bracket, and then attach the bracket together with the power supply to the computer enclosure. By this way, the power supply is assembled outside the assembly line, thereby avoiding the paralysis of the whole assembly line when an unworkable work site occurs. Examples are disclosed in Taiwan Patent Application No. 88219428. However, screws are still needed to fix the bracket to the computer enclosure. When maintaining or repairing the power supply, screwdrivers are needed to unscrew the screws to take the power supply off.
Thus, a mounting apparatus for a power supply which solves the above-mentioned problems is strongly desired.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a mounting apparatus with a simple structure which readily allows attachment and removal of a power supply to and from a computer chassis.
To achieve the above-mentioned object, a mounting apparatus in accordance with the preferred embodiment of the present invention is used to mount a power supply. The mounting apparatus comprises a computer chassis, a mounting board attached to the power supply, and a mounting bracket. The chassis comprises a rear panel with an opening, and first and second side panels. The mounting board forms a pair of mounting hooks at each side thereof. The mounting bracket comprises two mounting portions and a connecting portion. Each mounting portion defines a plurality of slits corresponding to the mounting hooks, and a plurality of locking holes. The rear panel forms a plurality of catches slidably engaging in the locking holes. After the power supply slides in the computer chassis with the mounting hooks extending in the corresponding slits, the mounting bracket is moved horizontally so that the hooks hook the rear panel. The second side panel is then attached to the chassis to prevent the mounting bracket from leaving the chassis.
In disassembly, the second side panel is removed, the mounting bracket is moved back to its original position, so that the mounting hooks disengage with the rear panel, and the power supply can be easily taken out from the computer chassis.
In this invention, the support bracket is received in the drive bracket with the pins slid in the slots, and by means of the latch attached to the drive bracket to secure one of the pins, so that the combined data storage device and support bracket is attached to the drive bracket. That is to say, the data storage device is secured to the drive bracket without screws, therefore simplifies the attachment and removal procedures.

A rectangular opening 52 is defined in an upper portion of the rear panel 50, having a size fitting the power supply 10. Two pairs of through holes 55 are defined respectively in the rear panel 50 at upper and lower sides of the opening 52. Two pairs of L-shaped catches 56 are formed inwardly from an inner face of the rear panel 50 at the upper and lower sides of the opening 52. A pair of guiding plates 62 is stamped inwardly from the first side panel 60, respectively corresponding to the upper and lower sides of the opening 52. A resilient finger 63 is stamped from each guiding plate 62. A slanted guiding lip 64 is formed from a rear end of each guiding plate 62. A pair of fixing hooks 66 is formed inwardly from the first side panel 60 corresponding to the fixing holes 16 of the power supply 10.
The mounting board 20 may be attached to a rear wall of the power supply by screws or other conventional means. A plurality of ventilating apertures (not labeled) is defined in the mounting board 20 corresponding to the ventilating apertures of the power supply 10. The mounting board 20 respectively forms two pairs of mounting hooks 25 at upper and lower edges thereof.
The mounting bracket 30 is generally U-shaped, and is integrally made by stamping and bending a piece of metal sheet. The mounting bracket 30 comprises two parallel mounting portions 31, 32, and a connecting portion 33 connecting the mounting portions 31, 32. Two pairs of slits 35 are respectively defined in the mounting portions 31, 32 corresponding to the through holes 55 of the rear panel 50. Two pairs of L-shaped locking holes 36 are defined in the mounting portions respectively corresponding to the catches 56 of the rear panel 50. A flange 34 is formed from each of the mounting portions 31, 32 and the connecting portion 33. A plurality of resilient tabs 37 is formed at the flanges 34.
Referring also to FIG. 3, the second side panel 70 is detached, the mounting bracket 30 is attached to the rear panel 50. The catches 56 of the rear panel 50 enter the locking holes 36 from larger ends thereof, and are slidably received in the locking holes 36. The mounting bracket 30 is thereby slidably attached to the rear panel 50.
Referring also to FIGS. 4-6, when the mounting bracket 30 is moved to a place where the slits 35 are in alignment with the through holes 55, the mounting bracket 30 is located at a first position. The power supply 10 fixed with the mounting board 20 enters the opening 52 of the rear panel 50, and slides along the guiding plates 62 of the first side panel 60 until the fixing holes 16 of the power supply 10 engages with the fixing hooks 66 of the first side panel 60.
