Title: Computer enclosure

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a computer enclosure. 
     2. Description of the Related Art 
     A computer enclosure of a computer generally includes a shielding panel attached to a rear wall of the computer enclosure. The shielding panel defines a plurality of I/O (input/output) accessing holes corresponding to connectors of the computer, which are ready for being coupled to peripherals, such as a display and a printer. The connectors should be kept engaged with the shielding panel, otherwise electromagnetic waves will leak through the I/O accessing holes to undesirably interfere with equipment near the computer, or even cause injury to users. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is an assembled, isometric view of a rear wall and a shielding panel of an exemplary embodiment of a computer enclosure, the shielding panel defines a plurality of I/O accessing holes each with a plurality of contacting strips. 
         FIG. 2  is a partial, sectioned view of  FIG. 1  taken along line II-II. 
         FIG. 3  is a schematic view, similar to  FIG. 2 , showing a connector inserted in one of the accessing holes of  FIG. 1 . 
     
    
    
     DETAILED DESCRIPTION 
     Referring to  FIGS. 1-3 , in an exemplary embodiment, a computer enclosure of a computer (not shown) includes a rear wall  10 , and a shielding panel  20  attached to the rear wall  10 . The shielding panel  20  defines a plurality of I/O (input/output) accessing holes  201 , corresponding to a plurality of connectors  300  of the computer. The connectors  300  include a display connector, a printer connector, a keyboard connector, a mouse connector, and so on. The shielding panel  20  includes a plurality of resilient and electrically conductive contacting strips  203  arranged around each of the I/O accessing holes  201  and extending into the computer enclosure. In one embodiment, each of the contacting strips  203  around each of the holes  201  extends slantingly from edges of the accessing hole  201  towards the center of the accessing hole  201 . Each of the contacting strips  203  is wavy in a lengthwise direction thereof to provide the contacting strip  203  with a elasticity. 
     To mount the connectors  300  to the shielding panel  20 , the contacting strips  203  are urged to deform towards insides of the shielding panel  20 . When the connectors  300  are inserted into the corresponding I/O accessing holes  201  of the shielding panel  20 , the contacting strips  203  are released, thereby restoring to resist against the corresponding connectors  300 . Therefore, the contacting strips  203  tightly contacting the connectors  300  prevent electromagnetic waves leaking from the I/O accessing holes  201  of the shielding panel  200 . 
     It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of its material advantages, the example hereinbefore described merely being exemplary embodiments.
