Title: Mounting apparatus for power supply

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to mounting apparatuses, and particularly to a mounting apparatus for securing a power supply to an electronic device. 
     2. Description of Related Art 
     A conventional computer system usually includes a power supply unit in a computer case. The installation of the power supply unit in the computer case usually involves the use of screws, which is inconvenient. Furthermore, the volume of the power supply unit is usually so big that the power supply unit sometimes deforms a rear plate of the computer case. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. 
         FIG. 1  is an exploded, isometric, cutaway view of a mounting apparatus in accordance with an embodiment. 
         FIG. 2  is an assembled, cutaway view of  FIG. 1 . 
         FIG. 3  is similar to  FIG. 2 , but shows a power supply in a different position. 
     
    
    
     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, according to one embodiment, is configured for securing a power supply  20  and includes a computer case  10  and a supporting member  30 . 
     The power supply  20  includes a top panel  21  and a side panel  23 . Two mounting holes  212  are defined in the top panel  21 , and a plurality of protuberances  213  are disposed on the top panel  21 . In one embodiment, the top panel  21  is substantially perpendicular to the side panel  23 . 
     The computer case  10  includes a bottom plate  12 , a rear plate  14  connected to the bottom plate  12 , a first side plate  18  connected to the rear plate  14  and the bottom plate  12 , and a second plate  19  connected to the rear plate  14  and the bottom plate  12 . In one embodiment, the first and second side plates  18 ,  19  are substantially parallel to each other and perpendicular to the bottom plate  12 . A flange  182  is connected to the first side plate  18  and extends into the computer case  10 . 
     An opening  142  is defined in the rear plate  14 , and a positioning assembly  145  extends from the opening  142 . The opening  142  is adjacent to the first plate  18 . The positioning assembly  145  includes a first positioning panel  144  and a second positioning panel  146 . The first positioning panel  144  is away from the first plate  18 . The second positioning panel  146  is connected to the rear plate  14  and the flange  182  of the first side plate  18 . In one embodiment, the second positioning panel  146  is mounted to the flange  182  by any suitable means, such as jointing or with screws. Two positioning holes  1462  are defined in the second positioning panel  146 , corresponding to the two mounting holes  212 . In one embodiment, the first positioning panel  144  is substantially perpendicular to the bottom plate  12 ; and the second positioning panel  146  is substantially parallel to the bottom plate  12 . 
     The supporting member  30  is attached to the bottom plate  12  and abuts the first side plate  18 . A bridge  31  is located on the supporting member  30 , for securing the first positioning panel  144 . A first through hole  32  and a second through hole  361  are defined in the supporting member  30 , and the second through hole  361  is larger than the first through hole  32 . A first retaining piece  35  extends from an edge of the first through hole  32 . A concave configuration  363  surrounds the second through hole  361 , for strengthening the configuration of the supporting member  30 . Two second retaining pieces  33 , adjacent to the first side plate  18 , are located an edge of the support member  30 . In one embodiment, the first retaining piece  35  and the first positioning panel  144  are located at a same plane; and the two second retaining pieces  33  are arranged in a line substantially perpendicular to the rear plate  14 . 
     Referring to  FIGS. 2 and 3 , in assembly, the power supply  20  is inserted into the opening  142  and moved in a first direction perpendicular to the rear plate  14 . The side panel  23  abuts the first positioning panel  144 , a side panel (not shown) opposite to the side panel  23  abuts the first side plate  18 , and the top panel  21  abuts the second positioning panel  146 . The power supply  20  is further moved in the first direction, until the power supply  20  is located between the first retaining piece  35  and the second retaining piece  33 . The two mounting holes  213  of the top panel  21  are aligned with the two positioning holes  1462  of the second positioning panel  146 . Two fixing members  50  are respectively inserted into the two mounting holes  213  and the two positioning holes  1462 , to mount the top panel  21  to the second positioning panel  146 . 
     In disassembly, the two fixing members  50  are removed from the second positioning panel  146  and the top panel  21 . The power supply  20  is moved in a second direction opposite to the first direction, and pulled out from the computer case  10 . 
     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.
