ABSTRACT:
A contact terminal for insertion into a plated through-hole of a printed circuit board is formed from thin metal stock of uniform thickness with a tubular compliant mounting section. A plurality of slits are spaced around the mounting section, and along one side of each slit are a pair of outward projections to engage the wall of the plated through-hole so that the metal on one side of each slit is deflected radially inwardly by the plated through-hole when the terminal is inserted, to mechanically secure the terminal therein. Outer edges of the projections along the slits penetrate the plating material during insertion. A method for making such a terminal includes piercing the mounting portion area of the blank, forming slits therein, forming projections along one side of each slit to extend out of the plane of the blank, and rolling at least that portion of the terminal into a tubular shape so that the pairs of projections extend radially outwardly.
