## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting brackets for attaching electronic components to equipment such as computer enclosures, and more particularly to a mounting bracket which can mount different types of power supplies having different configurations of screw holes.
2. Description of the Related Art
Many types of electronic equipment such as computer systems include power supplies which convert incoming alternating current to direct current. Direct current is suitable for operating various electrical components within such equipment. With the constant development of new electronic equipment, more and more components are required to be included within an electronic equipment enclosure. A power supply is generally one of the largest components in an electronic equipment enclosure. Thus the means of securing a power supply to electronic equipment determines the overall configuration of the equipment.
A power supply is often directly secured to a rear panel of a computer enclosure by screws. This makes the process of assembly unduly laborious and time-consuming. Furthermore, various different power supplies have screw holes located in a variety of different positions. Generally, a given rear panel defines a plurality of through holes, and can only fit one kind of power supply that has matching screw holes.
As a result, hinges have been developed to secure a power supply to an enclosure. Examples are disclosed in U.S. Pat. Nos. 5,172,305 and 5,745,342. The hinges allow the power supply to be pivotally moved out of its normal installed position, thereby allowing users to access other components in the enclosure adjacent the power supply. However, manufacturing of such hinges adds extra components and increases costs. In addition, it can be awkward and troublesome to attach a power supply to an enclosure using such hinges.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a mounting bracket which can easily and securely mount different types of power supplies having different configurations of screw holes to a computer enclosure.
To achieve the above object, a mounting bracket for mounting power supplies having various different configurations of screw holes to a computer enclosure in accordance with the present invention comprises a body attached to one power supply. A plurality of countersunk portions is defined in the body and configured such that selected of the through holes correspond to screw holes of the one of the power supplies. A fringe is bent forward from a top edge of the body. A middle portion of the fringe is bent upward and then rearward to form an L-shaped latch for suspending on a flange of the enclosure. A tab depends from a bottom edge of the body and defines a screw aperture for engaging with a screw which extends through the enclosure. A first rolled hook and a second rolled hook are formed outwardly from the body for engaging with the enclosure. A plurality of spring fingers is formed in the body around a periphery thereof, for electrically connecting with the enclosure.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with the attached drawings, in which:

FIG. 3 is an assembled view of FIG. 1.



DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, a mounting bracket 40 in accordance with a preferred embodiment of the present invention is provided for attaching a power supply 10 to a computer enclosure 20. The power supply 10 comprises a rear surface 12. A plurality of screw holes 14 is defined in peripheral portions of the rear surface 12. A ventilating grille 16 for heat dissipation is defined in a right portion of the rear surface 12. A mains socket 18 is formed in a left portion of the rear surface 12.
The enclosure 20 comprises a rear panel 22. An opening 24 is defined in an upper portion of the rear panel 22, for exposing the power supply 10 to an exterior of the rear panel 22. A through hole 26 is defined in the rear panel 22 below a middle of the opening 24, for extension of a screw 70 therethrough to engage in the mounting bracket 40. A flange 28 is bent inwardly from a top edge portion of the rear panel 22. A gap 30 is defined in a junction of a top right corner of the rear panel 22 and the flange 28.
The mounting bracket 40 comprises a rectangular body 41. A plurality of countersunk portions 52 is defined in peripheral portions of the body 41. Certain of the countersunk portions 52 correspond to the screw holes 14 of the power supply 10. The countersunk portions 52 are configured so that various different combinations thereof correspond to various different types of power supplies having various different configurations of screw holes. A first rolled hook 50 is formed from a right side edge of the body 21. First and second cutouts 54, 56 are defined in the body 41, for exposing the ventilating grille 16 and the socket 18 of the power supply 10 respectively to an exterior of the rear panel 22. A second rolled hook 58 is formed outwardly from the body 41 at a side extremity of the second cutout 56. A fringe 42 is bent forwardly from a top edge portion of the body 41. A middle portion of the fringe 42 is bent upwardly and then rearward to form a latch 44. A profile of the latch 44 is L-shaped. A tab 46 depends from a central portion of a bottom edge of the body 41. A screw aperture 48 is defined in the tab 46. A plurality of spring fingers 60 is formed in the body 41 around a periphery thereof, for electrically connecting with the rear panel 22.
Referring also to FIGS. 2 and 3, in assembly, the mounting bracket 40 is attached to the rear surface 12 of the power supply 10. Screws (not shown) are extended through the appropriate countersunk portions 52 to engage in the screw holes 14 of the power supply 10. The combined power supply 10 and mounting bracket 40 is then attached to the rear panel 22 of the enclosure 20. The latch 44 is supported on the flange 28, and suspends therefrom. The combined power supply 10 and mounting bracket 40 is pushed leftward until the first rolled hook 50 engages with an edge of the rear panel 22 in the gap 30 and the second rolled hook 58 engages with the rear panel 22 in the opening 24. The screw 70 is extended through the through hole 26 to engage in the screw aperture 48 of the mounting bracket 40. The spring fingers 60 are sandwiched between the body 41 and the rear panel 22 thereby electrically connecting the mounting bracket 40 and the enclosure 20. Thus, the combined power supply 10 and mounting bracket 40 is securely attached to the rear panel 22 of the enclosure 20.
In the present invention, the countersunk portions 52 of the body 41 of the mounting bracket 40 are configure so that various different combinations thereof correspond to various different types of power supplies having various different configurations of screw holes. Accordingly, the same mounting bracket 40 can be used to mount a variety of different types of power supplies 10.
While the present invention has been illustrated by the description of the preferred embodiment thereof, and while the preferred embodiment has been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications within the spirit and scope of the present invention will readily appear to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrative examples shown and described.
