However, a fundamental problem has arisen particularly in the formation of a connector in which female terminal pins are implanted in multiple rows. Since the shape of the female type terminal pin is complicated as shown in FIG. 6 with one end having two forks 23, 23, this is inserted into the mold in multiple rows and the terminal pin penetrates. Even if the support is formed and then removed from the mold, the female terminal pins are bifurcated, so that the multiple rows of the terminal pins are not separated from the mold. Also,
When it is attempted to implant the terminal pins on the support body in multiple rows by the press-fitting means, the support body may be broken during the press-fitting operation.

Therefore, an object of the present invention is to provide a connector for electronic equipment in which female terminal pins are also arranged in multiple rows on a support body.
