Plug connector, receptacle connector and connector assembly

A connector assembly, comprising:

• a plug connector, comprising:
• a board which has a board mating portion, a surface of the board mating portion being provided with multiple pairs of signal conductive pads and multiple ground conductive pads which are respectively provided at two sides of each pair of signal conductive pads, and
• a ground shielding cover which is mounted to the surface of the board mating portion, the ground shielding cover and the board together encircling at least parts of the multiple pairs of signal conductive pads;
• and
• a receptacle connector, comprising:
• an insulative body;
• and
• a terminal module which is provided to the insulative body, the terminal module comprising:
• a terminal group which comprises multiple pairs of signal terminals and multiple ground terminals;
• an insulative base which partially clads the terminal group;
• a first ground shielding member positioned at first side of the multiple ground terminals;
• and
• a second ground shielding member positioned at a second side of the multiple ground terminals, wherein
• the first ground shielding member, the second ground shielding member, and the multiple ground terminals together encircle the multiple pairs of signal terminals.
