Abstract: A low profile electrical connector assembly includes plug and receptacle connectors having mating dielectric housings each mounting a plurality of terminals which include contact portions for interengagement with the contact portions of the terminals of the other connector. The terminals include feet portions for surface connection to circuit traces on a pair of printed circuit boards. The terminals are generally U-shaped as defined by a first leg that is joined to the respective foot portion of the terminal and free spring contact leg that is engageable with the contact portion of one of the terminals of the other connector and preloaded on a shoulder of the respective housing. The first leg is fixed to the housing at a proximal end thereof with a distal end of the first leg being flexibly movable into a slot in the housing.
