Shielded stacking electrical connector assembly

An electrical connector assembly includes a receptacle member (14) and a pin shroud member (16) adapted to be mounted to opposite sides of a printed circuit board. Each receptacle member (14) is adapted to mate with a pin shroud member (16) mounted to another circuit board so that a parallel stack of circuit boards may be interconnected and supported. Each pin shroud member (16) has ground shields (60) which engage terminals (42) in the mating receptacle member (14). The ground shield (60) and the engaged terminal members (42) have pin portions (62, 64) extending through apertures of the respective circuit boards for connection to ground planes on the circuit boards. Each receptacle member (14) is also provided with further terminal members (36) having portions (38) which extend through respective apertures (35) in the circuit board and through the pin shroud member (16) mounted to the opposite side of the circuit board for engagement with corresponding terminal members (36) of a receptacle member (14) mounted to another circuit board, which latter receptacle member (14) is mated with the pin shroud member (16).
