[Embodiment] Please refer to the figure-picture, which is the first preferred embodiment of the present invention. The terminal 1 of the electrical connector (not shown) can be used for electrical purposes. A chip module (not shown) and a printed circuit board (not shown) are connected. The electrical connector (not shown) includes an insulative housing (not shown) and a plurality of terminals 1 housed in an insulative housing (not shown). The μ-insulating body (not shown) includes a rectangular plate-shaped base body (not shown), and the base body (not shown) is provided with terminal receiving holes (not shown) for accommodating the plurality of terminals 1 . Since the insulative body (not shown) is well known in the art, it will not be described in detail herein. The terminal 1 is formed of a sheet-shaped metal strip-body, which mainly includes a main body portion 10 having a substantially thin plate shape, an elastic portion 1 extending obliquely upward from the upper side of the main body portion 10 and toward the other side, and the main body portion 1 The lower side bends the extended welded portion 12 downward. The main body portion 10 has a balance portion 17 extending downward from both sides of the welded portion 12, and the balance portion opening extends downward until the bottom surface thereof is flush with the upper surface 14 of the welded portion 12. One of the upper ends of the upper end portion of the main body portion 10 is formed with the (four) portion 16' main body portion U). The upper end of the main body portion 10 is provided with the above-mentioned elastic portion 11 extending without the projection portion 16. 7 M349093 The elastic portion 11 is located on the same plane as the main body portion 10, and the elastic portion 11 includes a base portion η1 extending obliquely upward from the upper side of the main body portion 10 and toward the other side, and an elastic arm 112 extending obliquely obliquely from the base portion η. The base portion hi is tapered in the width direction of the terminal turn, and the width of the base portion lu is slightly smaller than the width of the main body portion 10. The joint portion 12 extends downward from the lower side of the main body portion 1 and is horizontally bent, and has a mounting portion (not numbered) formed at its end, and the welded portion 12 and the main body portion 1 are substantially 9 inches. Settings. A solder ball (not shown) solderable to a printed circuit board (not shown) is connected to the lower surface 15 of the soldering portion 12, and is usually soldered to a printed circuit board (not shown) by a difficult technique. The punched terminal 1 is subjected to secondary processing to further bend the end 113 of the elastic arm 112 of the elastic portion to form the contact portion 13. The contact portion 13 extends from the outer side (not labeled) of the end 113 of the elastic arm 112. The end H3 of the elastic arm m is located on the same plane as the plane of the main body portion 10 and the elastic portion 11. The contact portion 13 forms a lateral "L"-shaped structure with the end 113 of the resilient arm 112. The direction in which the contact portion 13 is bent is aligned with the direction in which the welded portion 12 of the terminal i is bent. The contact portion 13 is formed by secondary processing or bending of the elastic arm 112 of the terminal ,, that is, the contact portion 13 is extended by the outer side (not labeled) of the end (1) of the elastic arm η, instead of the conventional technology. The metal strip (not shown) is die-cut, so that the contact portion 13 has a smooth surface that abuts against a wafer module (not shown). When the wafer module (not shown in Fig. TF) presses the terminal 1, the elastic arm movable contact portion 13 moves downward. Therefore, the contact surface of the terminal that is in contact with the wafer module (not shown) is a smooth and flat metal surface, which can avoid damage to the wafer module (not shown) and improve the quality of contact with the punched surface. Thus the terminal river provides good electrical continuity. Referring to the second figure, which is the terminal 2 of the second preferred embodiment of the present invention, which differs from the first preferred embodiment in that the terminal 2 passes through the end 211 of its impurity. After the bend is formed into the contact portion 22, the contact portion 22 is advanced forward and downward to provide a contact end 23. A notch 24 is provided between the contact end a and the contact portion 22 to increase the elasticity of the contact end 23. The contact end is slightly higher than the contact portion 22 and is the highest point of the entire terminal 2. The second fold f forms a contact end 23 with a smooth surface at the end of the miscellaneous arm 21 to abut the wafer module (not shown), which can also effectively improve the contact quality of the end, and the 8 M349093 achieves good electrical connection function of the terminal 2. . Referring to the third figure, the terminal 3 of the third preferred embodiment of the present invention is disclosed, which is different from the foregoing two preferred embodiments in that the terminal 3 is formed by bending the end 311 of the elastic arm 31 thereof. The junction 32 of the "U" plane is formed substantially at the end 311 of the elastic arm 31. The bending opening direction of the miscellaneous 32 is the direction of the bending of the welded portion 3; The combination of the formation of the scales and the wafer module (not shown) _ can effectively improve the good electrical connection function of the terminal 3 of the terminal 3. u
