Abstract:
An electronic device includes a chassis, a power supply, and a bracket. The power supply is capable of supplying power to electronic elements secured in the chassis. A resiliently deformable latch piece is located on the power supply. A tab is located on the latch piece. The bracket is secured in the chassis and defines a slit. The slit receives the tab of the power supply so as to secure the power supply in the bracket, and the latch piece is resiliently deformable to disengage the tab from the slit to remove the power supply from the bracket.

     DETAILED DESCRIPTION 
       [0010]    Referring to  FIG. 1 , an electronic device in accordance with an embodiment includes a chassis  10 , a bracket  20  configured to be secured in the chassis  10 , and a power supply  40  configured to be secured in the bracket  20 . 
         [0011]    The chassis  10  includes a bottom plate  11  and a side plate  12  perpendicular to the bottom plate  11 . A motherboard  30  is secured in the chassis  10  on the bottom plate  11 . A plurality of positioning posts  112  are located on the bottom plate  11  beside the motherboard  30 , and arranged in one line. Each positioning post  112  includes a positioning head portion  1122 , and a positioning neck portion  1120  having a diameter smaller than a diameter of the positioning head portion  1122 . A plurality of securing posts  122  are located on the side plate  12 . Each securing post  122  includes a securing head portion  1222  and a securing neck portion  1220  having a diameter smaller than a diameter of the securing head portion  1222 . The securing posts  122  are arranged in two horizontal lines. A side plate flange  123  is bent perpendicularly from a front edge of the side plate  12 . 
         [0012]    The bracket  20  includes a top wall  21 , and first and second sidewalls  23 ,  25  bent perpendicularly down from opposite edges of the top wall  21 . A first sidewall flange  232  is bent perpendicularly out from a bottom edge of the first sidewall  23 . A plurality of positioning holes  234  are defined in the first sidewall flange  232  for receiving the positioning posts  112  of the chassis  10 . Each positioning hole  234  includes a circular positioning entry  235  and an elongated positioning slot  236  communicating with the positioning entry  235 . The positioning entry  235  has a diameter greater than the diameter of the positioning head portion  1122  of the positioning post  112 . The positioning slot  236  has a width smaller than the diameter of the positioning head portion  1122  of the positioning post  112 , but greater than the diameter of the positioning neck portion  1120  of the positioning post  112 . Two pairs of slits  238  are defined in the first sidewall  23  adjacent a front edge thereof, and arranged in a vertical line. A plurality of fixing holes  239  are defined in the first side wall  23 , and arranged in two horizontal lines. 
         [0013]    A plurality of securing holes  252  are defined in the second sidewall  25  for receiving the securing posts  122  of the chassis  10 , and arranged in two horizontal lines. Each securing hole  252  includes a circular securing entry  253 , and an elongated securing slot  254  communicating with the securing entry  253 . The securing entry  253  has a diameter greater than the diameter of the securing head portion  1222  of the securing post  122 . The securing slot  254  has a width smaller than the diameter of the securing head portion  1222 , but greater than the diameter of the securing neck portion  1220 . A plurality of mounting holes  255  are defined in the second sidewall  25 , and arranged in two horizontal lines. A second sidewall flange  257  is perpendicularly bent from a front edge of the second sidewall  25  of the bracket  20 , and perpendicular to the first sidewall flange  232 . 
         [0014]    The power supply  40  is shorter than the bracket  20 . A resilient latch piece  41  is located on a side of the power supply  40 . A pair of tabs  43  are located on the latch piece  41  configured for engaging in the corresponding pair of slits  238  of the first sidewall  23  of the bracket  20 . 
         [0015]    A connecting body  50  is configured to be secured in the bracket  21 . The connecting body  50  has two sockets  53  capable of electrically coupling with connectors (not shown) on rear walls of the power supply  40 , so that the power supply  40  can be electrically coupled to electronic elements, like the motherboard  30  secured in the chassis  10 , through the connecting body  50 . 
         [0016]    Referring also to  FIG. 2 , in assembly of the power supply  40 , the power supply  40  is coupled to the connecting body  50  with connections between the power supply connectors and the corresponding sockets  53 . The power supply  40  and the connecting body  50  are then together inserted in the bracket  20 . When the tabs  43  of the latch pieces  41  are pressed by the front edge of the first sidewall  23 , the latch pieces  41  are resiliently deformed. The power supply  40  and the connecting body  50  are further pushed to be inserted in the bracket  20 . When the tabs  43  align with the corresponding slits  238  of the first sidewall  23 , the latch pieces  41  rebound to engage the tabs  43  in the slits  238 . The power supply  40  and the connecting body  50  are thus secured in the bracket  20 . 
         [0017]    The power supply  40 , the connecting body  50 , and the bracket  20  are together placed in the chassis  10 . The positioning posts  112  are engaged in the corresponding positioning entry  236  of the positioning holes  234 , and the securing posts  122  are inserted in the corresponding securing entry  253  of the securing hole  252 . The bracket  20  is pushed to slide on the bottom plate  31  in a direction towards the side plate flange  123 . Until the power supply  40  abuts against the side plate flange  123 , the positioning neck portions  1120  of the positioning posts  112  are slid in the positioning slots  236  of the positioning holes  234 , and the securing neck portions  1120  of the securing posts  112  are slid in the securing slots  253  of the securing holes  252 , respectively. A first fastener (not shown) is screwed into the first sidewall flange  232  and the bottom pate  11  to prevent the positioning posts  112  and the securing posts  122  from removing from the positioning holes  234  and the securing holes  252 . The bracket  20 , the power supply  40 , and the connecting body  50  are thus secured in the chassis  10 . 
         [0018]    In disassembly of the power supply  40 , the first fastener is removed from the bracket  20  and the bottom plate  11 . The bracket  20  can be then be slid away from the side plate flange  123 . The positioning neck portions  1120  of the positioning posts  112  and the securing neck portions  1220  of the securing posts  122  are slid to the positioning entries  236  of the positioning holes  234  and the securing entries  253  of the securing holes  252 , respectively. The bracket  20 , the power supply  40 , and the connecting body  50  can then be removed from the chassis  10 . The latch pieces  41  are operated to resiliently deform until the tabs  43  disengage from the slits  238  of the bracket  20 . The power supply  40  together with the connecting body  50  can then be removed from the bracket  20 . 
         [0019]    Referring to  FIGS. 3-4 , two power supplies  60  in accordance with an alternative embodiment define a plurality of locking holes  61  corresponding to the fixing holes  239  of the bracket  20 . Each power supply  60  has a length generally equal to the length of the bracket  20 . 
         [0020]    The procedure of assembly and disassembly of the power supplies  60  are the same as with the power supply  40 , except that the power supplies  60  are secured in the bracket  20  with a plurality of second fasteners  80  engaging correspondingly in the locking holes  61  and the fixing holes  239 . 
         [0021]    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.
