Abstract
In a stamping step, when a stamping terminal piece formed as a connector terminal is stamped, an electric wire crimping part is stamped and extended from a chain part in a direction perpendicular to a feeding direction, an electric contact part is stamped and extended from the electric wire crimping part in a direction parallel to the feeding direction and a range to which a gold plating is applied by a gold plating step is not overlapped on a range to which a tin plating is applied by a tin plating step in the feeding direction.
Claims3
A method for manufacturing a connector terminal in which an electric contact part to be connected to a mate side male terminal is bent substantially at right angles to an electric wire crimping part to be crimped and connected to a coated electric wire, the method comprising:
- a stamping step of stamping from an electrically conductive metal plate a stamping terminal mold formed as the connector terminal under a state that the electric wire crimping part is connected to a belt shaped chain part and a plurality of stamped terminal pieces are connected to one side of the chain part;
- a gold plating step of applying a gold plating to the electric contact part;
- a tin plating step of applying a tin plating to the electric wire crimping part;
- and
- a bending step of forming the connector terminal by a bending work;
- wherein in the stamping step, the stamped terminal piece is stamped so that the electric wire crimping part is extended from the chain part in a direction that is perpendicular to a feeding direction in which the plurality of stamped terminal pieces are continuously arranged and the electric contact part is extended from the electric wire crimping part in a direction that is parallel to the feeding direction;
- and
- wherein a range to which the gold plating is applied by the gold plating step is not overlapped on a range to which the tin plating is applied by the tin plating step in the feeding direction.
