An electrical connector in the related art includes a body, a plurality of conductive terminals fixed to the body, a metal shielding plate and a metal mounting plate. The plurality of conductive terminals include a plurality of first conductive terminals and a plurality of second conductive terminals. The metal shielding plate is installed in the body, and located between the plurality of first conductive terminals and the plurality of second conductive terminals, so as to perform isolation and shielding functions and reduce signal crosstalk.
