A low profile board-to-board connector assembly includes a receptacle and a detachable plug. The receptacle has a receptacle housing with a plurality of arrayed first contacts mounted therein. Each first contact has a base portion, a first solder tail portion extending outwardly from one end of the base portion for connection with a first PCB, a retention portion perpendicular to the base portion, and a free first spring contact portion bent from the other end of the base portion and extending parallel to the retention portion. The plug has a plug housing with a plurality of arrayed second contacts mounted therein. Each second contact has a U-shaped portion with a pair of legs one of which is a free second spring contact portion and the other of which is a locking portion, and a second solder tail potion bent from an end of the locking portion and extending outwardly for connection with a second PCB. When the receptacle and the plug are assembled, the first spring contact portion can engage at its free end with the free end of the second contact portion thereby providing sufficient spring bias for reliable electrical contact with each other.
