Title:
接点端子の製造方法
Document Type and Number:
Japanese Patent JP5901959
Kind Code:
B2
Abstract:
A method for manufacturing a contact terminal including a contact portion that slides against a surface of a conductive contact plate. The manufacturing method includes forming a projection in a metal plate by performing a drawing process, wherein the projection projects in a thicknesswise direction of the metal plate and has a larger diameter than the contact portion. The manufacturing method further includes forming the contact portion from the projection by performing a contraction pressing process at least once on the projection so that the diameter of the projection gradually decreases, while the height of the projection remains the same or decreases in a stepwise manner.
