Abstract

An electrical receptacle connector includes a metallic shell, an insulated housing, first receptacle terminals, second receptacle terminals, a shielding plate, and a terminal organizer. The insulated housing is in the receptacle cavity of the metallic shell. The first receptacle terminals are assembled with the insulated housing. The second receptacle terminals are assembled with the terminal organizer. The insulated housing and the terminal organizer are assembled with each other. The shielding plate is between the first receptacle terminals and the second receptacle terminals. The terminal organizer extends the fixation portion attaching to the front portions of the second receptacle terminals, so that the front portions of the second receptacle terminals are securely held on the tongue portion. Therefore, when the terminal organizer is deformed due to heating, the front portions of the second receptacle terminals can be still fixed on the tongue portion without being deflected upwardly.
