Electrical receptacle connector

An electrical receptacle connector, comprising:

• a metallic shell comprising a receiving cavity;
• an insulated housing in the receiving cavity, wherein the insulated housing comprises a base portion and a tongue portion extending outwardly from one side of the base portion;
• the tongue portion has two faces, a front side surface, and two side surfaces, the front side surface is connected to front side portions of the two faces, and the two side surfaces are connected to two sides of the two faces;
• a plurality of terminals arranged in two rows and at the insulated housing, wherein the terminals comprise a plurality of contact portions, and the contact portions are at the two faces of the tongue portion;
• the terminals comprise a plurality of high-speed signal terminals, a plurality of low-speed signal terminals, a plurality of power terminals, and a plurality of ground terminals;
• the ground terminals are at two outermost sides of the power terminals, and the low-speed signal terminals are between the power terminals;
• in at least one of the two rows of the terminals;
• each of the high-speed signal terminals is between an adjacent one of the power terminals and an adjacent one of the ground terminals;
• a metallic plate at the tongue portion and between the terminals in the two rows, wherein each of two sides of the metallic plate has a protrusion, and a side portion of each of the protrusions is exposed from a corresponding one of the two side surfaces of the tongue portion;
• the metallic plate has a through hole, and the through hole has a plurality of through portions and a communication portion;
• the through portions are at the protrusions and correspond to front ends of the contact portions of the high-speed signal terminals;
• each of two sides of the communication portion is in communication with a corresponding one of the through portions, and the communication portion corresponds to front ends of the contact portions of the low-speed signal terminals.
