Problems solved by technology

[0002] At present, the known electrical connector includes an insulating body provided with a plurality of terminal receiving grooves, a plurality of terminals and solder balls, and the terminals can hold the solder balls, but the solder balls of this electrical connector cannot Therefore, it may cause uneven docking between the electrical connector and the circuit board, and an electrical connector disclosed in Taiwan Patent No. 094123035, the electrical connection includes an insulating base body with a plurality of terminal slots and a plurality of conductive terminals and a solder ball, the terminal includes a soldering portion and a contact portion, a hole is provided on the soldering portion, the solder ball can be movably accommodated in the hole, and the edge of the hole is provided with a chamfered angle
However, for this kind of electrical connector, because the chamfer requires secondary stamping to punch out, the production process is more complicated, and because the edge of the chamfer is not smooth, it may be scratched when the solder ball is moved therein.

Abstract

The invention relates to an electric connector which comprises an insulation body provided with a plurality of holding holes, and a plurality of terminals and solder balls held in the holding holes; the terminals are provided with via holes; the solder balls are held in the via holes; the edge of the via hole is provided with a round corner at a side towards the core of the solder ball. A method for manufacturing the electric connector of the invention comprises the steps that: the insulation body provided with a plurality of holding holes is provided; a sheet-metal is provided and punched into a terminal rough casting provided with a contact part and a welding part; the welding part of the terminal rough casting is punched with a via hole, and the side of the edge of the via hole forms a round corner; a flat-shaped terminal is bent towards the side provided with the round corner to form a terminal needed; the terminal is arranged in the holding hole, and the side provided with the round corner faces the interior of the holding hole; the solder balls are arranged in the holding holes, one side of the solder ball is connected with the lower edge of the via hole. The electric connector of the invention is well welded with a circuit board; in addition, the electric connector is provided with the round corners, thus preventing the solder balls from being scratched; the round corners can be formed when the via holes are formed, thus being relatively simple.
