Description of the invention: [Technical field to which the invention pertains] The present invention relates to an electrical connector, and more particularly to an electrical connector having a solder ball positioning structure. [Prior Art] U.S. Patent No. 5,997,317, U.S. Patent No. 6,095,842, U.S. Patent No. 6,099,321, U.S. Patent No. 6,113,411, U.S. Patent No. 6,113,412, U.S. Patent No. 6,116,922, U.S. Patent No. 6, No. 116, 923, U.S. Patent No. 6,132,222, U.S. Patent No. 6,142,81, U.S. Patent No. 6,142,811, U.S. Patent No. 6,171,156 B1, and U.S. Patent No. 6,2, , 8 〇 7 B1 and U.S. Patent No. 6,267,615 B1 and the like disclose a type of electrical connector for electrically connecting a crystal module and a printed circuit board to realize signal and data transmission therebetween. The above electrical connection! It comprises an insulative housing and a plurality of electrical connector terminals received in the insulative housing, the electrical connection being a terminal for soldering a solder ball to the corresponding solder joint of the printed circuit board.之前 Before the electrical connector is mounted on the _ circuit board, it is necessary to apply a layer of flux on the soldering end of the electrical connector, and then apply the solder to the soldering flux; ensure the electrical connector 1 Connected to the #性,电连接器" 吊权^ tin ball clamp structure to achieve accurate positioning of the solder ball. Crying and uncovering - an electrical connection with a solder ball positioning structure, which is accurately positioned. However, the above-mentioned solder ball positioning is called extrusion deformation, and the solder ball can be implanted on the side wall of the corresponding electrical connector terminal ^ receiving groove, and cannot be fixed to the phase when the solidification is in the electrical connection of the electrical connection. Reliability. There are at least the following defects in the connector terminals: Exact 5 51 1281290 ί]: The ft-bit hole' process is complicated and cumbersome; when the solder ball is melted, the action is self-contained; == is connected to the periphery of the positioning hole, and is susceptible to external force [invention Contents] Knot (four) face paste, reliable positioning to connect the above technical problems, the electrical connector terminal of the original electrical connector is connected. Θ 3 fold of the claws 'base # 触 claws together define the containment of the ball to accommodate the empty ball ΐΐΐϊ ί ί ' 'The electrical connector of this creation has at least the following advantages: when the tin is connected to the accommodating space of the benefit terminal, from the base The four corners of the same direction bend the touch two: connect 5, 'borrow ί can prevent the financial relative to the electrical connection 11 terminal to produce the wrong solid German can be this ^ ^ electrical connection between the benefits of the contact area is larger, solder ball sleek, condensation connection On the terminal, the solder ball can be electrically operated. [Embodiment] The electrical three-figure diagram is described in the present invention. The present invention relates to an electrical connector for (not shown) and a printed circuit board (not shown). It includes a plurality of electrical connector terminals 10 that the insulative housing af should be received in the insulative housing. As shown in the first figure, the electrical connector terminal 10 includes a substantially rectangular plate-shaped base=folded contact claw 106 on the connecting printed circuit board-seat portion. The claw 106 is concavely curved and extends from the base portion 104 and the inner side wall (10) of the curved outer concave contact 106 to receive the solder ball 20. The curved outer finger 106 is 形ίίΠ, corresponding in size, when the solder ball 20 is placed in the accommodating space to bite? The inner side wall 1〇8 of the claw i abuts against the solder ball 2〇. Please refer to the second and third figures. The solder ball 20 is made of 60-40, and the # 10 102 - /, he yoke method, the solder ball 20 can also be made of other fusible materials. . 6 1281290 In this mode, the electrically connected terminals are made of copper alloy base mineral nickel, and the nickel surface forms an inert oxide layer in the ambient atmosphere. At this time, the solder ball 2〇 cannot be moved directly to the soldering portion of the electrical connector terminal 1〇, and a flux is required to be applied to the soldering portion to improve the wettability and solderability of the soldering portion 1〇2. The coating ' can be applied only to the base 104, or the base 104 * four fingers 106 can be integrally coated. In the ball-making system, when the ambient temperature reaches the melting point of the solder ball 2, it is placed on the end of the electrical connector im, the ball 2〇 begins to melt, and the molten solder ball 20 is connected to the solder by the surface tension of the surface. It is roughly spherical. After cooling and solidification, the solder balls 20 are simultaneously fixed to the inner side wall 108 of the base portion 104 and the contact claws 106, and are generally arranged in a jff cloth and an arc phase, and are in contact with the tin wiper. n / Valley work, base 1邛4 and the inner side wall of the contact claw 106 1 〇 8 position ·, ^ 埶 2μ, can prevent the solder ball 2 〇 from generating an error S-Τί 20 with respect to the electrical connector terminal 20 104' The ί terminal can be positioned with a large combined force. The accuracy of the solder ball 20 on the electrical connector terminal 10 is accurate, ok, and not described. This creation has indeed been consistent with the hair, and the above is only the spirit of the present invention. According to the invention, the simple drawing of the drawings should be covered by the following patents.
