The conductive terminal of the electrical connector has a flat base for holding the conductive terminal in the terminal receiving groove of the insulative housing. The top end of the base portion is extended with one arm, and the connecting arm extends upwardly with an arm portion. The top end of the arm portion is horizontally and the contact surface of the contact portion of the wafer module is electrically connected to the arc. Shape [0003] Since the pins of the wafer module may be contaminated by foreign matter, such as dust, before contact with the conductive terminals of the electrical connector, ifc will affect the electrical contact-effect when it is in contact with the conductive terminals. The contact surface of the base exposed terminal is curved | « , which is relatively smooth, and the torsion shoulder and the stress in contact with the stitch are small, so the contamination ability to the pins of the chip module is poor, so the electrical conduction effect is affected. In view of this, it is necessary to overcome the defects of the above-mentioned conductive terminals. [New Content] [0005] The technical problem solved by this creation is to provide a conductive terminal with good electrical contact with the wafer module. [0006] In order to solve the foregoing technical problem, the present invention provides a conductive terminal for the form numbering of the form number A0101, page 4/14, and the chip module, the conductive terminal including a flat base extending upward from the base a pair of connecting arms and a welding portion extending downward from the base, wherein the connecting arm end is provided with a contact portion, the contact portion includes a guiding portion and a clamping portion adjacent to the guiding portion, and the opposite faces of the clamping portion are a contact surface, the contact surface being recessed with a groove, the side edge of the groove forming a contact edge for the pin to slide along and form a final contact therewith. Compared with the prior art, the conductive terminal of the present invention is provided with a relatively sharp contact edge, and the contact between the contact edge and the chip module can increase the contact stress between the conductive terminal and the pin, and improve the conductive terminal to The ability of foreign objects on the pins to improve the electrical contact between the conductive terminals and the pins. [Embodiment] -.-Λ·:·.黛m' > : [0008] Referring to the first figure, the present disclosure discloses a conductive terminal 1 connected to .ii, mainly for use with a wafer mold having a pin 2. Group (not shown) is electrically connected. Referring to the first to fourth figures, the conductive terminal 1 is provided with a flat base portion 10, a welded portion 12 extending downward from the base portion 10, and a connecting arm 11 extending upward from the base #10. The center portion of the base portion 10 extends to the left by two or more, respectively, and has a holding portion 13, which extends downward and is flush with the bottom surface of the welded portion 12. Two pairs of convex portions 131 and 132 are disposed on the two sides of the holding portion 13 to be engaged with the insulating body (not shown) of the electrical connector, wherein one of the upper convex portions 131 is located at a position lower than the convex portion 132 The width of the convex protrusions on both sides is narrow [0010] The welded portion 12 is perpendicular to the base portion 10, and the welded portion 12 is connected to the base portion 10 by the bent neck portion 15. The soldering portion 12 is for connecting a solder ball (not shown) and soldering it to a circuit board (not shown) by solder balls. Form No. A0101 Page 5 of 14 [0011] M414689 The connecting arm 11 is located above the holding portion 13, and is disposed on the left and right sides of the base 1 and is bent forward to protrude from the base 1 flat. The connecting arm 11 includes an upwardly extending first connecting arm 110 and a second connecting arm that is bent upward from the first connecting arm 11〇. The second connecting arm U1 is bent at the end to be substantially horizontally rearward. The extended contact portion 14. The contact portion 14 is disposed to be in contact with a pin 2 of a wafer module (not shown), and the contact portion 14 includes a guiding portion 140 and a clamping portion 141 adjacent to the guiding portion 140. The guiding space between the two guiding portions 14 is gradually narrowed and narrowed for guiding the stitch 2 into the clamping portion 141 for holding the stitch 2. Referring to the fourth figure, the clamping portion ίο has a contact surface 141 相对 opposite to the stitch 2, and the yoke 14 is provided with a groove 1411, and the side edge of the sinuous groove 1411 is danced. The steel contact is connected to the contact edge 1412, and the contact edge m2 is horizontally slipped and finally contacted by the needle '2 in the clip 141. [0012] Referring to the first and fourth figures, the cross section of the Chinese contact 1412 is gradually tapered from the root to the tip, and the lacking tip is located at the clamping portion 141. The surface of the groove i41 is formed by cutting -I : : i ^ on the contact surface 1410, and the back surface of the contact surface 141 is a flat surface without forming a convex portion. It is trapezoidal, but is not limited thereto, and may be in a "V" shape or the like. [0013] The contact portion 14 of the conductive terminal 1 of the present invention is disposed obliquely with respect to the horizontal direction 'in the present embodiment, the guide portion 丨4 〇 is coplanar with the second connecting arm lu, the contact surface 1410 is inclined with respect to the horizontal direction, the upper end thereof is relatively close, and the contact edge 1412 is disposed at the upper edge of the contact portion 14. In other embodiments, the contact surface 1410 can also be opposite to The horizontal direction is inclined so that the lower form number A0101 is 6th/14th, and the M414689 end is relatively close, and the contact edge 1412 is disposed at the lower edge of the contact portion 14. Since the contact edge 1412 of the contact portion 14 is sharp, when The stitch 2 is horizontally slid from the guide portion 140 into the grip At 141, the stitch 2 slides along the contact edge 1412 of the clamping portion 141 and contacts each other to generate a large contact stress, thereby scraping the foreign matter on the stitch 2, ensuring stable and good electrical conduction between the stitch 2 and the conductive terminal 1.
