Tongue plate with improved signal shielding effect

A tongue plate, made of a printed circuit board and configured to be inserted into a mating connector, the tongue plate comprising:

• a plurality of first conductive pads comprising a first signal terminal group, a first ground terminal located on one side of the first signal terminal group along a first direction, and a second ground terminal located on another side of the first signal terminal group along the first direction;
• and
• a conductive shielding assembly comprising a first conductive shielding plate in contact with the first ground terminal, a second conductive shielding plate in contact with the second ground terminal, and a connecting plate connecting the first conductive shielding plate and the second conductive shielding plate;
• the first conductive shielding plate extending substantially all the way along the first ground terminal so as to be overlapped with a majority length of the first ground terminal along a second direction;
• the second conductive shielding plate extending substantially all the way along the second ground terminal so as to be overlapped with a majority length of the second ground terminal along the second direction;
• the first conductive shielding plate, the second conductive shielding plate and the connecting plate jointly forming a first conductive shielding cavity;
• the first signal terminal group being located at a first opening of the first conductive shielding cavity along a third direction;
• wherein each two of the first direction, the second direction and the third direction are perpendicular to each other.

A tongue plate, configured to be inserted into a slot of a mating connector, comprising:

• a plurality of first conductive pads comprising a first signal terminal group, a first ground terminal located on one side of the first signal terminal group along a first direction, and a second ground terminal located on another side of the first signal terminal group along the first direction;
• and
• a conductive shielding assembly comprising a first conductive shielding plate in contact with the first ground terminal, a second conductive shielding plate in contact with the second ground terminal, and a connecting plate connecting the first conductive shielding plate and the second conductive shielding plate;
• the first conductive shielding plate and the second conductive shielding plate respectively extending along a second direction;
• the first conductive shielding plate, the second conductive shielding plate and the connecting plate jointly forming a U-shaped first conductive shielding cavity;
• the first signal terminal group being located at a first opening of the first conductive shielding cavity along a third direction;
• wherein the first signal terminal group comprises a first signal terminal and a second signal terminal;
• wherein the first signal terminal comprises a first mating portion and a first connecting portion connected to the first mating portion;
• the second signal terminal comprises a second mating portion and a second connecting portion connected to the second mating portion;
• the first ground terminal comprises a first contact portion and a first connection portion connected to the first contact portion;
• the second ground terminal comprises a second contact portion and a second connection portion connected to the second contact portion;
• both the first contact portion and the second contact portion extend forwardly to protrude beyond a first front end of the first mating portion and a second front end of the second mating portion;
• the first connecting portion protrudes toward the second connecting portion along the second direction, so that a first recess is formed on a side of the first connecting portion away from the second connecting portion;
• the first connection portion at least partially protrudes into the first recess;
• the second connecting portion protrudes toward the first connecting portion along the second direction, so that a second recess is formed on a side of the second connecting portion away from the first connecting portion;
• the second connection portion at least partially protrudes into the second recess.
