Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a mounting apparatus, and particularly to a mounting apparatus for mounting an input/output connector with low electromagnetic interference leakage. 
     2. Description of Related Art 
     An input/output (I/O) connector is a robust connector electrically connected to various circuits for interfacing signals between different peripheral devices and a host computer. However the signal transmission through the I/O connector results in electromagnetic interference (EMI) leakage. Therefore, a need may be desired to provide a low EMI leakage solution for mounting the I/O connector.

     The base  20  may include a plate  21  and two sidewalls  22  substantially perpendicular to the plate  21 . A plurality of chambers  23  is disposed on an interior side of the plate  21 . Each of the plurality of chambers  23  may accommodate one of the plurality of I/O connectors  10 . At least one guide groove  221  is defined on an exterior side of each of the two sidewalls  22 . A wedge-shaped block  223  protrudes from a bottom bed of each of the at least one guide groove  221 . A hollow cylinder  225  is located at each of the two sidewalls  22 . Two limiting grooves  211  are defined in an exterior side of the plate  21 . The base  20  is made of electrically non-conductive material such as plastics. 
     The cover  30  may include a board  31  and a plurality of latching pieces  32  downwardly (viewed in the aspect of  FIG. 1 ) extending from the edges of the board  31 . A latching hole  321  is defined in each of the plurality of latching pieces  32 . A plurality of securing slots  311  are defined in pairs in the board  31 . Each pair of the plurality of securing slots  311  is adjacent to the front edge of the board  31  (viewed in the aspect of  FIG. 1 ). Two limiting channels  312  are defined on an exterior side of the board  31  and two positioning posts  313  are located on an interior side of the board  31 . The cover  30  is made of electrically non-conductive material such as plastics. 
     The shielding case  40  may include a top wall  41 , a bottom wall  42  substantially parallel to the top wall  41  and a front wall  43  perpendicular to the top wall  41  and the bottom wall  42 . Two restricting pieces  411  are defined in the top wall  41 . Two spring clips  421  are defined in the bottom wall  42 . A plurality of insertion holes  431  for exposing the ports  12  of the plurality of I/O connectors  10  is defined in the front wall  43 . The shielding case  40  is made of electrically conductive material such as metal. The shielding case  40  may be installed in a metal chassis of a computer system (not shown) and electrically connected to the metal chassis. 
     Each of the plurality of resilient pieces  50  may include a main body  51 , a first end  52  and a second end  53 . The first end  52  and the second end  53  extend from two opposite edges of the main body  51  along two opposite directions. An obtuse angle is defined between the first end  52  and the main body  51 . Another obtuse angle is defined between the second end  53  and the main body  51 . The second end  53  is an isosceles trapezoid. Two securing pieces  54  extends from the other opposite edges of the main body  51  and the two securing pieces  54  are substantially perpendicular to the main body  51 . Each of the two securing pieces  54  includes a wedge-shaped protrusion  541 . Each of the plurality of resilient pieces  50  is made of electrically conductive material such as metal.

The wedge-shaped protrusion  541  of each of the two securing pieces  54  is snap joint with a corresponding one of the plurality of securing slots  311  so as to prevent each of the plurality of resilient pieces  50  from moving away from the board  31  of the cover  30 . The plurality of resilient pieces  50  are secured to the cover  30 . 
     Each of the plurality of I/O connectors  10  is put into one of the plurality of chambers  23  of the base  20 . The cover  30  is moved above the base  20 . Each of the two positioning posts  313  is aligned with corresponding one of the hollow cylinder  225  and each of the plurality of latching pieces  32  is aligned with corresponding one of the at least one guide groove  221 . The cover  30  is moved towards the base  20  and each of the plurality of latching pieces  32  slides into the corresponding one of the at least one guide groove  221  until the plurality of latching pieces  32  are all latched to the at least one guide groove  221  by respectively engaging the latching holes  321  with the wedge-shaped block  223 . The two positioning posts  313  are inserted into the hollow cylinder  225 . Thereby, each of the plurality of I/O connectors  10  is fixed in one of the plurality of chambers  23  and the first end  52  of each of the resilient pieces  50  abuts the housing  11  of a corresponding one of the plurality of I/O connectors  10 . The second end  53  of each of the resilient pieces  50  exposes out of the assembly of the plurality of I/O connectors  10 , the base  20 , the cover  30  and the resilient pieces  50 . 
     Referring to  FIGS. 6 and 7 , when installing the assembly of the plurality of I/O connectors  10 , the base  20 , the cover  30  and the resilient pieces  50  into the shielding case  40 , each of the plurality of I/O connectors  10  is aligned with corresponding one of the plurality of insertion holes  431 . The assembly of the plurality of I/O connectors  10 , the base  20 , the cover  30  and the resilient pieces  50  is moved into an accommodating room (not shown) formed by the top wall  41 , the bottom wall  42  and the front wall  43  of the shielding case  40 . The two restricting pieces  411  of the shielding case  40  are respectively received in the two limiting channels  312  of the cover  30 . The two spring clips  421  of the shielding case  40  are respectively received in the two limiting grooves  211  of the base  20 . Thereby, the two restricting pieces  411  abut the board  31  of the cover  30  and the two spring clips  421  abut the plate  21  of the base  20 . The second end  53  of each of the resilient pieces  50  abuts the interior side of the front wall  43  of the shielding case  40 .
