Description

  The present invention relates to a DC power jack, and more particularly to a positive conductive structure applied to a DC power jack of a two-way jack connector.

  1 and 2 show a general two-port jack connector 10. FIG. This is an integrated connector having an earphone jack 12 and a DC power jack 13, and is generally called a DC power / earphone jack. Since the two-way jack connector 10 provides two functions of connection to a DC power supply and earphone connection, as shown in FIG. 3, it is often used on the circuit board 25 of the mobile phone 20. The mobile phone 20 is provided with functions of battery charging and earphone use.

  The structure of the DC power jack 13 of the two-way jack connector 10 is substantially the same as the structure of a general DC power jack, and includes a positive conductive terminal 14, a ground terminal 15, and a negative conductive terminal 16 having the same structure. In particular, the main body including the two-port jack connector 10 has a portion forming a connection pin by adding a curve to the rear end of the positive electrode conductive terminal 14 together with the connection pin portion of the ground terminal 15 and the negative electrode conductive terminal 16. The front end of the positive electrode conductive terminal 14 is exposed only on the rear surface of the positive electrode conductive terminal 14 by fitting and fixing the middle portion of the positive electrode conductive terminal 14 to the main body 11 of the two-port jack connector 10. The jack 13 is positioned and fixed in the insertion tank.

  However, since the means for fixing the positive electrode conductive terminal 14 on the main body 11 having the two-port jack connector 10 relies solely on the method of fitting the middle portion of the positive electrode conductive terminal 14, the positive electrode conductive The structure is such that the force for firmly fixing the terminal 14 is insufficient and stable fixing cannot be obtained. Therefore, after a certain period of use, the phenomenon that the positive conductive terminal 14 is loosened and moves easily occurs, and the DC conductive terminal 13 of the two-way jack connector 10 and a general DC power jack are both positive conductive. Poor electrical contact of the terminal 14 is likely to occur, causing a problem or failure in charging the mobile phone 20.

  In view of the above-mentioned problems, the present invention improves the structure of a general DC power jack and the DC power jack of a two-way jack connector so that the main body of the DC power jack or the two-way jack connector and its positive conductive set component are connected. The present invention is to provide a DC power jack of a two-way jack connector capable of firmly fixing the connector and solving the problems of loosening and poor contact.

  Further, the present invention includes a conductive rod and a conductive plate piece, which are fixed on a main body of a general DC power jack or a main body of a two-way jack connector, and are firmly connected to the main body of the DC power jack or the two-way jack connector. It is an object of the present invention to provide a positive electrode conductive set component having a structure coupled to a positive electrode.
