<p>A low profile electrical connector assembly (10) includes plug and receptacle connectors (12, 14) having mating housings (16, 26) each mounting a plurality of terminals (40, 42) each of which include contact portions (44, 58) for interengagement with the contact portions of the terminals of the other connector. The terminals further include mounting portions (46, 50) for surface connection to circuit traces (48, 52) on respective printed circuit boards (24, 34). The receptacle terminals (42) are generally U-shaped and are defined by a first leg (54) joined to the mounting portion (50) of the terminal and a free spring contact leg (56) having a contact portion (58) engageable with the contact portion (44) of one of the terminals of the other connector. The contact portion (58) is preloaded on a shoulder (64) of the receptacle housing. The first leg (54) of the terminal (42) includes a proximal end (54a) fixed to the housing and a distal end (54b) movably supported along its edges by tabs (55) to permit a portion of the first leg between the proximal end and the distal end to be flexibly movable into a slot (62) in the housing during mating of the connectors. The secondary support of the terminal at its distal end by the tabs (55) distributes stresses along the first leg (54) to improve deflection characteristics of the receptacle terminal. <IMAGE></p> |
