New Description: [New Technology Field] [0001] The present invention relates to an electrical connector and a conductive terminal thereof, and more particularly to an electrical connector electrically connectable to a printed circuit board and a conductive terminal thereof . [Prior Art] [0002] With the continuous development of electronic technology, there is an increasing demand for the electrical conduction effect between a chip module such as a central processing unit and a printed circuit board. Moreover, while the function of the chip module is more powerful, the number of required pins is increasing and the volume is not relatively enlarged, how to design an appropriate electrical connector to connect the high-density pins of the chip module to the printed circuit board becomes quite important. In particular, the electrical connector must be more stable and reliable when electrically connecting the chip module, and the contact impedance is also required to be as low as possible to reduce the energy loss of the wafer module in high-frequency transmission. The Chinese Patent Publication No. 2747729 discloses such conventional techniques that the conductive terminals of the electrical connector..::: is provided with a base portion, a welded portion extending downward from the base portion, and extending upward from the base portion. One pair of arms. A contact portion electrically connected to the pins of the wafer module is formed at an end of the arm portion. The conductive terminal wastes a lot of materials during molding, which is not conducive to cost saving. In view of this, it is indeed necessary to provide an improved electrical connector and its conductive terminals to overcome the drawbacks of the aforementioned electrical connectors and their conductive terminals. [New content] _] The technical problem solved by this creation is that the electrical connector and its conductive terminal have three contact parts for the conductive terminals, and can effectively save the material form number A0101 Page 3 / Total 12 pages M382622 material.

At the same time, the second arm 23 is provided with a second contact portion 232, so that the conductive terminal 2 is formed with three contact portions electrically connected to the pins 3 of the wafer module, thereby effectively ensuring the stability of the contact. The welded portion 24 has a flat plate structure which is located on the same side of the fixed portion 21 as the second arm 23. A solder ball 4 is soldered to the soldering portion 24, and the conductive terminal 2 is soldered to the printed circuit board.
