Electrical connector assembly for mounting on a printed circuit board

An electrical connector assembly for mounting on a printed circuit board which includes a plurality of solder tail receiving apertures wherein the diameters of said apertures may vary within a predetermined range, comprising:

• a housing;
• means for mounting the housing on the printed circuit board and supporting the housing against lateral movement relative to the board;
• and
• a plurality of contact members mounted on the housing and each including a one-piece solder tail for positioning in an appropriate aperture in the printed circuit board, the solder tail having a generally straight side and a projecting hook on an opposite side the hook comprising two inclined intersecting surfaces, one surface adapted to contact the top surface of the printed circuit board when the solder tail is inserted into the aperture for guiding the solder tail into the aperture, the other inclined surface adapted to engage the bottom surface of the printed circuit board for retaining the connector assembly on the printed circuit board, the width of the solder tail between the straight side and the outermost point of the hook on the opposite side being no greater than the diameter of the smallest aperture within said range, and the centerline of the solder tail between said sides being offset, in the direction of the hook, relative to the centerline of any of said apertures within said range when the housing is supported on the printed circuit board.
