Electrical connector with improved shielding features

An electrical connector, comprising:

• an insulating body comprising a mating surface and a first mating slot extending through the mating surface;
• the first mating slot being configured to receive a first mating module along a mating direction;
• and
• a first terminal module comprising a first insulating block, a plurality of first conductive terminals fixed to the first insulating block, and a first ground sheet located on one side of the first insulating block;
• wherein each first conductive terminal comprises a first fixing portion, a first elastic contact arm extending from one end of the first fixing portion, and a first tail portion extending from another end of the first fixing portion;
• the first fixing portion is fixed to the first insulating block;
• the first elastic contact arm comprises a first contact portion protruding into the first mating slot;
• the plurality of first conductive terminals comprise a plurality of pairs of first differential signal terminals, a plurality of first ground terminal and a plurality of second ground terminal;
• two sides of each pair of first differential signal terminals are associated with one first ground terminal and one second ground terminal, respectively;
• the first elastic contact arm of the first ground terminal defines a first through hole;
• the first ground sheet comprises a first base portion;
• the first base portion comprises a first engaging portion in contact with the first fixing portion of the first ground terminal, a second engaging portion in contact with the first fixing portion of the second ground terminal, a first raised portion connecting adjacent first engaging portion and second engaging portion, and a first grounding elastic arm extending from the first engaging portion;
• the first raised portion is configured to avoid a corresponding pair of first differential signal terminals;
• the first grounding elastic arm is at least partially inserted into the first through hole;
• the first grounding elastic arm comprises a first abutting portion;
• the first contact portion of the first elastic contact arm of the first ground terminal is spaced apart from the first abutting portion of the first grounding elastic arm along the mating direction;
• the first contact portion of the first elastic contact arm of the first ground terminal and the first abutting portion of the first grounding elastic arm are configured to be in contact with a first ground conductive pad of the first mating module.
