ABSTRACT:
A surface mounted connector (25) for interconnecting closely centered circuits such as those carried by circuit boards (12, 18) includes plug and receptacle housings (24, 90) which internest to interconnect edge mounted, thin stamped contacts (50, 116) on centers complementary those of said circuits which include a contact configuration producing a series of point contacts (70, 128) and solder wells (70, 130) to provide an improved solder joint between respective contacts and boards. The contacts extend outside the side walls of the housings (64, 164) to facilitate heat application for solder reflow and inspection of solder joints. The contacts further have barbs (66, 126) engaging the said housings to hold the contacts against displacement upon separation of the plug from the receptacle. Solder pads (76) are provided on each housing to mechanically hold the housing to a board, and the plug housings include bevels (34) and polarizing and aligning plastic posts (44) which fit in recesses (96) in the receptacle to facilitate blind mating with latching surfaces (48, 100) latching the plug and receptacle together. A method is taught which features a tapering of beam lengths of the plug contact (50) to reduce stress and optimize force and/or deflection characteristics.
