Abstract: An electrical connector is provided for mounting on a surface of a printed circuit board having a plurality of holes. The connector includes a dielectric housing having a plurality of terminal-receiving passages. A plurality of first conductive terminals are mounted in some of the passages and include first tail portions insertable in an insertion direction into the holes in the printed circuit board with an interference fit. A plurality of second conductive terminals are mounted in other of the passages and include second tail portions engageable with the surface of the printed circuit board. The second tail portions are constructed to exert forces on the connector in a direction opposite the insertion direction away from the printed circuit board.
