A board-to-board connector assembly for connecting two printed circuit board is disclosed and includes interengaging plug and receptacle connectors that each have terminal-receiving cavities with conductive terminals disposed therein. Each of the terminals includes a tail portion that extends out of its respective connector for attaching the terminal to a circuit on the circuit board, and an elastic contact portion for contacting an opposing terminal of a mating connector. The elastic contact portion of the receptacle connector is bent at least twice upon itself to form a "Z" shape and to have plural elastic curved portions. An end of the elastic contact section is bent enward to form a contact face. The plug connector terminals have convex contact portion extending from their associated tail portions. The convex contact portion resiliently protrudes out of the plug connector and is located between the lower elastic curved portion and the contact portion of the connector pin, and an upper surface of the convex contact portion is in contact with a lower surface of the contact portion, when the connector housing and the assembling body are assembled together. In connector assemblies of the present invention, the convex contact portions of the plug connector are not separated from engagement with the receptacle connector terminals, even when an abrupt impact is applied from the exterior, so that contact stability and contact force for an electric connection between the connector terminals are improved.
