PURPOSE: To provide a pin header adaptable to its thinning and to provide its manufacturing method by reducing the deviation of an upper-stage contact and the warpage of a housing as a whole during insert-molding, by improving flatness accuracy and by enhancing the wrenching strength of a fitting part. CONSTITUTION: This pin header is insert-molded into such a form that multiple pin contacts 12A are arranged in an upper and lower two tiers and threaded in an insulation housing 13 having a rectangular solid shape. In the pin header, each of the pin contacts is composed of a fitting part 14 horizontally projecting from the front face of the housing, a leg part 15A extending downward from the rear end of the fitting part, and a flat part 16 horizontally extended by bending the lower end part of the leg part outward at a nearly right angle and surface-mounted to a printed circuit board. In each of the pin contacts arranged on the upper tier with respect to the housing within the pin contacts, a bent leg part 19 extending by being bent outward at a nearly right angle from the leg part and extending by being bent downward at a nearly right angle is formed between the leg part and the flat part, the leg parts of the upper-tier contacts are embedded in the housing by insert-molding, and the bent leg parts are projected toward the rear side of the housing along with the flat parts. |
