Plug connector and receptacle connector

A plug connector, comprising:

• a plug housing comprising a base extending transversely and a tongue portion extending forwardly from the base;
• a first set of plug terminals positioned in the plug housing as an upper row and comprising a plurality of first ground terminals and a plurality of first signal terminals, each first ground terminal and each first signal terminal having a first plate-shaped contact portion positioned on an upper surface of the tongue portion;
• a second set of plug terminals positioned in the plug housing as a lower row and comprising a plurality of second ground terminals and a plurality of second signal terminals, each second ground terminal and each second signal terminal having a second plate-shaped contact portion positioned on a lower surface of the tongue portion;
• a first plate-shaped shielding member provided below the first plate-shaped contact portions of the first set of plug terminals, the first plate-shaped shielding member comprising multiple first welding portions and first transverse shielding plate portions of which each are connected between every two corresponding first welding portions, the multiple first welding portions being welded to the first plate-shaped contact portions of the plurality of first ground terminals, and the first transverse shielding plate portions transversely crossing and covering the first plate-shaped contact portions of the corresponding first signal terminals without contacting the corresponding first signal terminals;
• and
• a second plate-shaped shielding member provided above the second plate-shaped contact portions of the second set of plug terminals, the second plate-shaped shielding member comprising multiple second welding portions and second transverse shielding plate portions of which each are connected between every two corresponding second welding portions, the multiple second welding portions being welded to the second plate-shaped contact portions of the plurality of second ground terminals, and the second transverse shielding plate portions transversely crossing and covering the contact portions of the corresponding second signal terminal without contacting the corresponding second signal terminal;
• wherein the first plate-shaped shielding member is positioned above the second-plate shaped shielding member adjacent the first set of plug terminals and the second plate-shaped shielding member is positioned below the first plate-shaped shielding member adjacent the second set of plug terminals.
