An electrical connector assembly comprises a receptacle connector (2) having a first insulative housing (20) and a plug connector (1). The first insulative housing comprises a pair of opposed sidewalls (24) defining a cavity (25) therebetween, and windows (23) defined in the sidewalls. A plurality of first contacts (22) are disposed in the cavity and each comprises a mating portion (222), a free end (220) and a solder portion (221). The free end extends outward of the sidewall through the window when the plug connector is completely inserted into the receptacle connector for facilitating visual identification by the user.
