BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to jacks, particularly to an audio jack connector used in an electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Electronic devices, such as mobile phones, have an audio jack. The audio jack has a connector, which needs to be electronically connected to a plurality of contacts of a printed circuit board of the electronic device. However, the connector is not easy to align with the contacts on the printed circuit board, so it will effect the electronic connection ability. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0011]      FIG. 1  shows an audio jack connector  20  used in an electronic device  100  according to an exemplary embodiment. The electronic device  100  may be mobile phone. The electronic device  100  comprises a housing  10  and a printed circuit board (PCB)  15 . 
         [0012]    The housing  10  is positioned at an outside of the electronic device  100 . The housing  10  has a main body  11  and a side plate  12  perpendicularly connected to the main body  11 . The side plate  12  defines a through hole  121 . Two positioning posts  111  are located on the main body  11 . 
         [0013]    The connector  20  comprises an insulating body  21 , a conductive element  25 , a plurality of elastic sheets  30  and a flexible printed circuit board (FPCB)  35 . The conductive element  25  and the plurality of elastic sheets  30  embedded in the insulating body  21 , and are electronically connected to the FPCB  35 . 
         [0014]      FIGS. 3 and 4  show that the insulating body  21  has a jack portion  22  and a receiving portion  23  being integral together. The jack portion  22  comprises a first surface  210 , a second surface  211 , two opposite sidewalls  212  and two opposite end walls  213  connected to each other. Each sidewalls has  212  has an extending plate  214  for engaging with the positioning posts  111  of the main body  11 . One of the end walls  213  has a cylindrical seat portion  215  for receiving a plug. The seat portion  215  defines a plug hole  216  and a slot  217  communicating with each other. The receiving portion  23  is located at one of the sidewalls  212 . The receiving portion  23  defines a plurality of cutouts  231  for receiving the plurality of elastic sheets  30 . 
         [0015]    The conductive element  25  is secured at one side of the insulation body  21  and has a contact  253  exposed from the slot  217 . The elastic sheets  30  are spaced apart and arranged in the cutouts  231  of the insulation body  21 . Each elastic sheet  30  comprises a latching portion  321 , an arcuate portion  322 , and a conductive portion  323  being integral together. The latching portion  321  is latched in the receiving portion  23 . The arcuate portion  322  elastically abuts against the PCB  15 . The conductive portion  323  is electronically connected to the FPCB  35 . The FPCB  35  has a first plate portion  351  and a second plate portion  352 . The first plate portion  351  is positioned under the jack portion  22 , and the second plate portion  352  is positioned under the receiving portion  23 . 
         [0016]    In assembly, referring to  FIG. 5 , the conductive element  25  is embedded in the insulation body  21 , and allows the contact  253  to be exposed from the slot  217 . The elastic sheets  30  are spaced apart and arranged in the cutouts  231  of the insulation body  21 . The FPCB  35  is positioned at one side of the connector  20 , and the second plate portion  352  electronically abuts against the conductive portions  323 . Then, the connector  20  is assembled to the main body  11  of the housing  10 , and the seat portion  215  is aligned with the through hole  121  of the side plate  12 . The extending plates  214  are engaged with the two positioning posts  111  for securing the connector  20  to the housing  10 . Thus, the assembly process of the audio jack connector is completed. 
         [0017]    The PCB  15  lays on top of the connector  20 , and electronically abut against the elastic sheet  30 . Thus, the conductive element  25  is electronically connected to the PCB  15  via the FPCB  35 . 
         [0018]    It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
