Stacked electrical connector

The utility model discloses a stack electric connector which comprises an insulating body, a plurality of conductive terminals disposed on the insulating body, a metal shielding shell covering the insulating body, and a metal shielding piece disposed on the insulating body. The insulating body comprises a main body part and a positioning seat installed on the main body part. The shielding shell comprises a housing which covers the insulating body, and also comprises an inner housing which is embedded in the insulating body. The shielding piece is disposed inside the positioning seat and partly extends out from the positioning seat. The shielding piece abuts against the inner housing. The shielding piece directly contacts with the inner housing for electrical connection. The inner housing is located between an upper terminal group and a lower terminal group. Through the above setting, the signal crosstalk between the upper terminal group and the lower terminal group is reduced, and the effect of signal transmission of the connector is improved.
