Title: Assembled structure of a connector

Description:
FIELD OF THE INVENTION  
      The present invention relates to an assembled structure of a connector, particularly to a structure in which the I/O port and connector socket can be connected with the printed circuit board (PCB) fast.  
     BACKGROUND OF THE INVENTION  
      In traditional connectors, spring jackwires in the I/O port and beam contacts in the connector socket are welded with the PCB to form I/O terminals for signals. Usually, in PCB of such a connector, terminals must cross the PCB to form a through conductive pole in the holes, thus spring jackwires in the I/O port and beam contacts in the connector socket are connected to the PCB in a way of welding or pressing, and such a structure can match wires upon and under the surface of the PCB.  
     SUMMARY OF THE INVENTION  
      However, in such an assembled structure of said traditional connector, spring jackwires in the I/O port and beam contacts in the connector socket are connected to terminals on the PCB in a way of welding or pressing, the method is difficult and cost lots of time. Furthermore, in the PCB of such a connector, terminals crossing the PCB will form a through hole structure; which will cause capacitance efficiency and crosstalk among wires. Therefore, an object of the present invention is to solve disadvantages of structure of traditional connector.  
      The present invention relates to an assembled structure of connector, so as to one or more limitations or disadvantages in said related art.  
      An assembled structure of a connector according to the present invention comprises a PCB, an I/O port and a connector socket configured in a jack frame, wherein spring jackwires in the I/O port and beam contacts in the connector socket form spring plates, so that the spring plates can get a close contact with corresponding terminals and the jackwire block and the connector block can be fixed on the PCB when the jackwire block in the I/O port and the slot in the connector socket joins corresponding terminals on the PCB respectively.  
      An assembled structure of a connector according to the present invention has the following advantages:  
      1. In assembled structure of a connector according to the present invention, the spring plates formed by spring jackwires in the I/O port and beam contacts in the connector socket enable the jackwire block in the I/O port and the slot in the connector socket to join said PCB to fix on said PCB.  
      2. In assembled structure of a connector according to the present invention, the spring plates formed by spring jackwires in the I/O port and beam contacts in the connector socket enable to stably contact, so welding is avoided and the assembling can be implemented by PCB being inserted in said I/O port or said connector socket.  
      3. With the assembled structure of a connector according to the present invention, the spring plate structure formed by spring jackwires in the I/O port and beam contacts in the connector socket enables to said spring plates to change their size or position to match the layout of wires on said PCB; thus crosstalk can be reduced according to the match with layout of wires.  
      4. With the assembled structure of a connector according to the present invention, the spring plate structure formed by spring jackwires in the I/O port and beam contacts in the connector socket can match the layout of wires on the PCB, so the through conductive hole structure through PCB is unnecessary, therefore capacitance efficiency and crosstalk can be avoided.

      A PCB ( 1 ), which has a plurality of wires ( 11 ) (act as signal channel), wires ( 11 ) form a plurality of jackwire terminals ( 12 ) and connector terminals ( 13 ) at the front or back of the said PCB in a one-one manner. Moreover, said jackwire terminals ( 12 ) and said connector terminals ( 13 ) are both formed by metal layer.  
      Referring to  FIG.3 , an I/O port ( 2 ) has a plurality of spring jackwires ( 21 ) and said spring jackwires ( 21 ) correspond to said each jackwire terminal ( 12 ) in a one-one manner, each spring jackwire is fixed at the front of a jackwire block ( 22 ) respectively so that each spring jackwire ( 21 ) is electrically insulated with each other, said jackwire block ( 22 ) is hollow and can be embedded in said PCB ( 1 ), and each spring jackwire ( 21 ) extends downwards to inside of said jackwire block ( 22 ) to form a spring plate ( 21   a ) with deflection.  
      Referring to  FIG. 4  and  FIG. 5 , a plurality of beam contacts ( 31 ) are arranged on a connector socket ( 3 ) and corresponds to said connector terminals ( 13 ) in a one-one manner, and each connector terminal ( 13 ) is respectively fixed in said connector socket ( 3 ), so each connector terminal ( 13 ) can be electrically insulated with each other, a slot ( 32 ) is formed at the bottom of said connector socket ( 3 ), said slot ( 32 ) can be embedded in said PCB ( 1 ), so that bottom of each beam contact ( 31 ) can extends downwards to inside of said slot ( 32 ) to form a spring plate ( 31   a ) with deflection. Moreover, said connector socket ( 3 ) particularly refers to two connector sockets ( 3 ) in left and right symmetry.
