FIELD OF THE INVENTION  
       [0001]     The present invention relates to a hinge and particularly to a hinge located in an electronic device having at least two bodies pivotally coupled to each other.  
       BACKGROUND OF THE INVENTION  
       [0002]     For present electronic devices having at least two bodies pivotally coupled to each other, at least a hinge is generally employed for opening and closing. The hinge structure may have different designs and be symmetrical or asymmetrical.  
         [0003]     Refer to  FIG. 1  for a conventional electronic device  1  that has at least two bodies pivotally coupled to each other. It includes a first body  10 , a second body  20  and a hinge  30 . The second body  20  may be pivotally coupled to the first body  10  through the hinge  30 .  
         [0004]     More specifically, the second body  20  has a wire set  21  (including signal cable and power cord) passing around the hinge and through a recess  12  in the first body  10  to couple with a connector  11 .  
         [0005]     The design of hinge set forth above has drawbacks, notably: 
        1. During assembly operators have to pull the wire set  21  (including signal cable and power cord) of the second body  20  to the recess  12  to couple with the connector  11 . The recess  12  usually has a space constraint that could hinder operators&#39; movements.     2. For maintenance technicians and users who want to do inspection and repairs, the wire set  21  (including signal cable and power cord) has to be separated from or coupled with the connector  11  in the recess  12 . It is also not convenient.
