An electrical receptacle connector includes a plurality of first terminals, a plurality of second terminals, a first insulator, a second insulator, a shielding plate and a third insulator. The first insulator includes a first front insulating portion and a first rear insulating portion. The first front insulating portion covers a part of each of the first terminals. The second rear insulating portion covers another part of each of the first terminals. The second insulator partially covers each of the second terminals. The third insulator partially covers each of the first terminals, the second terminals, the first insulator, the second insulator and the shielding plate.
