To this end, the prior art provides an electrical connector that includes an insulating body, a plurality of conductive terminals that are nested in the insulative housing, and a cover sheet disposed on the insulative housing. The conductive terminals include a __ and a face-and-weld portion extending in a vertical direction. The elastic arm is provided with a curved piece, and the first and second parts of the conductive terminal are placed on the insulating body. The cover sheet is placed on the insulating body to make the first contact portion of the conductive terminal. Extend the cover sheet to guide the crystal to add == electric = 'skills from the fine: the layout of the fiber structure is complex, and the package is connected to σσ and Lu, the design of the cymbal will be more complicated. It is not enough to overcome the above drawbacks. It is indeed necessary to design an improved electrical connector to overcome the conventional technology, M312066. [New content] The purpose of this creation is to provide a kind of structure that can prevent the conductive terminals from falling off from the insulating body towel and the structure. Simple electrical connector. To this end, the present invention provides an electrical connector for electrically connecting a chip module and a printed circuit board, comprising an insulative housing having a terminal receiving slot and a plurality of conductive terminals received in the terminal receiving slot. The cross-sectional area of the upper portion of the terminal trough is larger than the cross-sectional area of the lower portion. The conductive terminals include a waist portion and resilient arms and welds extending outwardly from opposite ends of the waist, respectively. The welded portion has a substantially "L" shape, and a bump protruding from the outside of the welded portion is provided near the waist portion, and a groove is formed on the side wall of the terminal receiving groove corresponding to the bump on the welded portion. - Compared with the prior art, the junction between the welded portion and the waist portion of the conductive terminal of the present electrical connector is just received in the groove of the groove on the terminal receiving groove. Meanwhile, the bump on the welded portion abuts on both sides of the groove In this way, the electrical connection H does not fall from the terminal receiving slot. Moreover, since the cross-sectional area of the upper part of the terminal receiving groove is larger than the cross-sectional area of the lower part, the conductive terminal enters from the lower opening of the terminal receiving groove, and enters two inches. When the conductive terminal of the elastic lion moves to the upper portion, the space is enlarged due to the increase in space. Therefore, the conductive terminal does not easily fall off from the lower portion of the terminal receiving groove. [Embodiment] Please refer to the first and second figures. The connector i is used to connect two separate electronic components, such as a wafer module (not shown) and a printed circuit board (not shown), which includes an insulative body 10 having a plurality of terminal receiving slots 102. And contained in The corresponding terminal receiving groove carries the conductive material 20. The Ding, and the rim body 10 includes a surface 1 相对 opposite to the wafer module, a surface 101 opposite to the printed circuit board, and a surface extending through the upper surface. The terminal receiving groove 1 〇 2 of the lower surface 101. The reduced area of the upper portion of the terminal receiving groove is larger than the cross-sectional area of the lower portion, and the side wall of the lower surface has a smooth plane, and the other side wall is provided with a groove 103. The conductive terminal 20 is received in the terminal receiving groove, and includes a waist portion 2 and a resilient arm 201 and a detailing portion 202 extending outward from the ends of the waist coffee. The elastic arm 2〇1 is substantially in the shape of a It includes a first arm portion 2010 and a second arm portion 2〇11 parallel to the first arm portion 2010, wherein the first arm portion 7 M312066 and the first 2011 are provided with a chip module at the bottom of the u-shaped portion thereof. Contact portion 2〇12 in contact. The welded portion 202 is substantially i-L-shaped, and a bump 2021 protruding from the outside of the welded portion is provided near the waist portion 2 (four). After assembly, the welded portion 2导电2 of the conductive terminal 2〇 is assembled. The junction with the waist 2 刚 is just accommodated in the groove 103 on the side wall of the terminal folding groove 102 And the bump period on the soldering portion 2〇2 abuts on both sides of the groove. In addition, at least two joints 2020 welded to the same solder joint a of the printed circuit board are disposed on the bottom of the soldering portion 2〇2. "When the conductive terminal 2 is mounted in the terminal receiving groove 1〇2, the elastic arm of the conductive terminal 2 is removed from the bottom of the "u"-shaped structure, and one end of the groove 1〇3 is provided along the terminal receiving groove 102, because The opening π cross-sectional area of the lower part of the terminal accommodating vessel causes "u, the bottom of the shape structure is compressed, and the conductive terminal % is continuously pushed into the terminal accommodating groove, and the terminal accommodating groove is moved as the push-in progresses. The cross-sectional area of the upper portion is continuously increased, so that the bottom of the "U"-shaped structure of the conductive terminal 2 is expanded due to the space becoming large, until the bumps moved by the welded portion are abutted on both sides of the groove 1〇3. The conductive terminal 2〇 will no longer move upwards, and the “U”-shaped structure portion is opened to the maximum. In this way, the conductive terminal % can be operated up or down to complete the transmission, and the floating conductive terminal 2 can be better placed in the terminal receiving slot.
