Abstract:
A surface mount connector including a male part and a female part to be mounted onto respective printed circuit boards so that the printed circuit boards can be connected by mating said male part and said female part together, each printed circuit board having conductor pads on a surface thereof, the conductor pads being arranged in two lines on each side of a given midline so that the first line of the conductor pads is closer to the midline than the second line of the conductor pads on each side of the midline, and so that the conductor pads of the first line are staggered with respect to those of the second line on each side of the midline, wherein:said male part comprises an insulating housing and a plurality of male contact pieces which are mounted to said insulating housing in two lines so as to be symmetrically arranged relative to a midline of said insulating housing, each of said plurality of male contact pieces having two lead projections placed apart from each other so that the lead projections may be put into contact with conductor pads of the first and second lines when said male part is mounted on a respective one of the printed circuit boards, wherein some of said male contact pieces are positioned to have first lead projections of said two lead projections in contact with the conductor pads of the first line and second lead projections of said two lead projections out of contact with any of the conductor pads, and others of the male contact pieces are positioned so as to have second lead projections of said two lead projections in contact with the conductor pads of the second line and have first lead projections of said two lead projections out of contact with any of the conductor pads; and said female part comprises a second insulating housing and a plurality of female contact pieces which are mounted to said second insulating housing in two lines so as to be symmetrically arranged relative to a midline of said second insulating housing, each of said plurality of female contact pieces having two lead projections placed apart from each other so that the lead projections may be put into contact with conductor pads of the first and second lines when said female part is mounted on a respective one of the printed circuit boards, wherein some of said female contact pieces are positioned to have first lead projections of said two lead projections in contact with the conductor pads of the first line and second lead projections of said two lead projections out of contact with any of the conductor pads, and others of the female contact pieces are positioned so as to have second lead projections of said two lead projections in contact with the conductor pads of the second line and have first lead projections of said two lead projections out of contact with any of the conductor pads.
