New description: [New technical field] The connection between the chip module and the circuit board is related to a conductive terminal, in particular to an electrical conductive terminal. [Prior Art] A conventional conductive terminal can electrically connect a wafer module to a circuit board, and the conductive terminal is integrally formed by metal scraping, and includes a base portion, a holding portion extending upward from the base portion, and a body extending downward from the base portion 'Connected. The engaging portion is bent to extend a mating portion, and the engaging portion is bent upward to extend a contact portion of the bent hook, and the contact portion is for electrically contacting the die module. The soldering portion and the solder ball are soldered to the second body. Since the area of the soldering portion is small, when the electrical connector is oscillated or collided, the solder ball is easily knocked off from the welded portion of the conductive terminal, thereby causing unreliable connection. Affects the electrical connection between the circuit board and the chip module. Therefore, it is necessary to improve the aforementioned conductive terminals to overcome the drawbacks of the prior art. [New content] The purpose of this creation is to provide a conductive terminal that can increase the soldering surface and hold the solder ball. The conductive terminal of the present invention is realized by the following technical solutions: a conductive terminal for electrically connecting the chip module to the circuit board, comprising: a holding portion, a fitting portion extending from an upper end side of the holding portion, and a self-mating The side of the portion extends a contact portion that contacts the wafer module and a solder portion Φ that is soldered to the circuit board. The edge of the welded portion is bent downward to be in contact with the solder ball. Compared with the prior art, the conductive terminal of the present invention increases the contact surface welded with the solder ball by the contact leg and can effectively prevent the tin cracking phenomenon occurring during the soldering process. [Embodiment] Referring to the first and second figures, the conductive terminal 2 of the present invention is used to electrically connect a chip module (not shown) to a circuit board (not shown), which includes a flat plate. The holding portion 2 of the structure, the fitting portion 21 extending upward from the upper end side of the holding portion 20, the welded portion 22 for connecting a circuit board (not shown), and a supporting portion 24 extending from the side of the mating portion 21 And a transition portion 28 that connects the welded portion 22 and the holding portion 2〇. Wherein, the upper end and the lower end of the opposite side edges of the holding portion 20 are provided with a plurality of outwardly protruding barbs 200, and the bottom edge of the barbs 200 located at the lower side of the holding portion 20 protrudes downwardly with a chamfer of an arc structure. 201. The lower end of one side of the mating portion is connected to the support of the strip structure by a bent portion 23. M356267 4 24 'The top end of the self-supporting portion 24 is bent to extend horizontally and obliquely upwardly - and the hook 27 is provided. The contact portion 26, the core arm 25 is electrically connected at its free end. The soldering portion 22 is a horizontal sheet body, and is used for the convex portion from the wafer module (not shown to be bent-to-contact leg 29, the contact leg 29 and the solder ball 3) are outwardly convex. Stretching and downward, please refer to the second figure. The conductive terminal of the present invention is 2^f. The solder ball 30 can be wrapped in the contact ball to hold the solder ball at the rear end of the solder ball. Soldering the solder ball 3〇 to the conductive end 'avoids that the conductive terminal 2 is oscillated by the arrangement of the extended contact leg 29, which increases the phenomenon that it is connected with the tin H: 22 day temple, and the soldering portion 22 is connected. , from __ stability == product ', therefore, will not be in the guide of the creation of the welding "Zi 2 财 _ 22 ° ° = transfer to the 22 woven _ 29 extension ^ u θ opposite sides or welded parts 22 before the edge μ, the fine work of the marriage, can be Ming Dazao #© welding can also play the role of holding the tin ball 3 接. And to prevent the cracking of the tin to the description, this creation has indeed met the new patent The patent application is filed in accordance with the law. However, the preferred embodiment of the invention is not based on the above-mentioned implementation method.
