An electrical connector includes an insulative housing, a number of conductive terminals affixed to the insulative housing, and a shielding plate affixed to the insulative housing. The insulative housing includes a base portion and a mating tongue extending forwardly from the base portion. The conductive terminals are exposed to two opposite surfaces of the insulative housing. The conductive terminals are arranged in upper terminals and lower terminals in two rows. Each row of conductive terminals include a number of high frequency signal terminals. The insulative housing includes a number of receiving slots located at a peripheral edge thereof for inserting the shielding plate to shield between the two rows of conductive terminals.
