FIELD OF THE INVENTION 
       [0001]    The present invention relates to a connector device; more particularly, relates to fabricating a connector device with saved fabricating time, fabricating process and fabrication cost and with better electromagnetic interference (EMI) restraining and electronical characteristics 
       DESCRIPTION OF THE RELATED ART 
       [0002]    A general connector device, as shown in  FIG. 4 , comprises a metal case  6 , a USB connector  7  in the metal case  6 , and an RJ45 connector  8  piled up with the USB connector  7  in the metal case  6 , where the RJ45 connector  8  comprises a circuit board  81 , choke coils  82  on the circuit board  81 , electrical components  83  on the circuit board  81 , and an external terminals seat  84  on the circuit board  81 ; the choke coil  82  has a circular coil stand  821 ; the circular coil stand  821  is coiled with a leading wire  822 ; and the connector device is electrically connected with external wires through the USB connector  7  and the RJ45 connector  8 . 
         [0003]    Although the RJ45 connector  8  is connected with an external connector, the choke coil  82  for the RJ45 connector  8  is complex, where, especially for a (high frequency) gigabit Ethernet, a sum of twelve choke coils may be required in a small area for the RJ45 connector  8 . Hence, high technology is required and fabrication cost are high with a long fabricating time and a complex fabricating process. Moreover, cross talk, return loss and EMI restraining may occur among the choke coils so that electronical characteristics of the connector device become worse. Hence, the prior art does not fulfill users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0004]    The main purpose of the present invention is to fabricate a connector device with saved fabricating time, fabricating process and fabrication cost and with better EMI restraining and electronical characteristics 
         [0005]    To achieve the above purpose, the present invention is a connector device having an H-shaped coil stand comprising a metal case having openings on an end surface; a first connecting unit in the metal case corresponding to an opening case; and a second connecting unit in the metal case corresponding to another opening, where the second connecting unit is piled up and fixed with the first connecting unit; the second connecting unit has a circuit board; the circuit board has at least one set of components corresponding to each other; the components comprises a choke unit, a terminals seat and external terminals; the circuit board has at least one choke unit comprising an H-shaped coil stand and a leading wire; and the leading wire is coiled around the H-shaped coil stand and is connected with the circuit board. Accordingly, a novel connector device having an H-shaped coil stand is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0011]    The following description of the preferred embodiment is provided to understand the features and the structures of the present invention. 
         [0012]    Please refer to  FIG. 1  and  FIG. 2 , which are a front view and a perspective view showing the preferred embodiment according to the present invention. As shown in the figures, the present invention is a connector device having an H-shaped coil stand, comprising a metal case  1 , a first connecting unit  2  and a second connecting unit  3 . 
         [0013]    The metal case  1  comprises two covers  11 , 12 ; and has a plurality of openings  13 , 14  on an end surface. 
         [0014]    The first connecting unit  2  is located in the metal case  1 ; and is corresponding to at least one of the openings  13 . The first connecting unit  2  has at least one insulated shell  20 . The insulated shell  20  has a plurality of connectors  21 , 22  piled up; and has a plurality of connecting terminals  221 , 222  at bottom. The insulated shell  20  is conformed to an insulated shell standard for an USB connector. 
         [0015]    The second connecting unit  3  is located in the metal case  1 ; and is corresponding to at least another one of the openings  14 . The second connecting unit  3  is piled up and fixed with the first connecting unit  2 ; and has a circuit board  31 . The circuit board  31  has several sets of components corresponding to each other, where the components comprise a choke unit  32 , 33 , a terminals seat  34 , external terminals  35  and electrical components  36 . The circuit board  31  comprises a first choke unit  32 , which comprises an H-shaped coil stand  321  and a leading wire  322  that is coiled around the H-shaped coil stand  321  and is connected to the circuit board  31 . The circuit board  31  further comprises a second choke unit  33 , which comprises a circular coil stand  331  and another leading wire  332  that is coiled around the circular coil stand  331  and is connected to the circuit board  31 . Thus, a novel connector device having an H-shaped coil stand is obtained, where, on fabricating the connector device, the circuit board  31  and the choke units  32 , 33  are designed to save fabricating time, fabricating process and fabrication cost. 
         [0016]    Please refer to  FIG. 3 , which is a view showing a state of use of the preferred embodiment. As shown in the figure, connecting terminals  221 , 222  for a first connecting unit  2  and a second connecting unit  3 , together with external terminals  35 , are connected with a main board  4 , where external connectors  5 , 5   a  are electrically connected with the first connecting unit  2  and the second connecting unit  3  through openings  13 , 14  of a metal case  1 . When connectors of the first connecting unit  2  and the second connecting unit  3  are connected with the external connectors  5 , 5   a , the present invention obtains better electromagnetic interference (EMI) restraining and electronical characteristics by using choke units  32 , 33  on a circuit board  31  of the second connecting unit  3 . 
         [0017]    To sum up, the present invention is a connector device having an H-shaped coil stand, where, on fabricating the connector device, a fabricating time, a fabricating process and a fabrication cost are saved and better EMI restraining and electronical characteristics are obtained.
