Electric connector and production method therefor

The invention discloses a method for producing an electric connector. The method comprises the following steps of providing a grounding metal sheet; arranging an inner insulating base on the grounding metal sheet in an injection molding manner; forming a first positioning bearing part, positioned on the upper side of the grounding metal sheet, and forming a second positioning bearing part, positioned on the lower side of the grounding metal sheet, on the inner insulating base; providing a first conductive terminal group, enabling the first conductive terminal group to be fixedly placed on the first positioning bearing part; providing a second conductive terminal group, enabling the second conductive terminal group to be fixedly placed on the second positioning bearing part so as to enable the metal sheet, the inner insulating base, the first conductive terminal group and the second conductive terminal group to form an assembling body together; arranging an outer insulating base on the assembling body in an in
