Description

M269597 IV. Creation Description (1) Technical Field of Creation This creation relates to an electrical connector, and in particular refers to the structure of a solder ball of an electrical connector. Prior art

Please refer to FIG. 1, which is a structure of a lap solder ball of a conventional electrical connector, which includes a base 10 and a plurality of terminals 15. The base 10 is provided with a plurality of terminal slots 11 and the plurality of terminals 15. A plurality of terminal grooves are provided, one end of the terminal is provided with a contact portion 16, and the other end of the terminal is provided with a horizontal connecting piece 17 ', the connecting piece 17 is recessed in the middle to form a cup, and a ball is welded on it. 1 9. The above structure has the following defects: 1. It is coated with solder paste on the connection piece 17 before processing, and then the solder ball 19 is placed on each connection piece 17 with a jig alignment. Such processing is very labor-intensive. .

2 · The bottom end of the solder ball 19 is welded to the horizontal connecting piece 丨 7. Since the warm contact point is below, in order to make it easy to be heated during heating, the base body 丨 〇 cannot be provided around the solder ball 19 The peripheral wall is used to locate the solder ball (if there is a peripheral wall, it will block the heat, which is not conducive to heating and welding). The solder ball can only be placed on the connecting sheet by the depression in the middle of the cup. The ball method is not stable enough, especially when the solder ball contacts of the connector are denser, the smaller the solder ball and the cup body of the connecting piece, the poorer the positioning effect of the solder ball placed on the connecting piece 17 becomes. 3 · There is no barrier around each solder ball, when the solder ball gap is very small
