An electrical connector assembly, comprising:
- an electrical connector, comprising a plurality of electrical modules sequentially stacked along a vertical direction and fixed by at least one fixing mechanism, wherein each of the electrical modules comprises an insulating block being arc-shaped, a row of conductors fixed to the insulating block and arranged along a left-right direction perpendicular to the vertical direction, and at least one first shielding member provided to cover the insulating block, a front-rear direction is defined to be perpendicular to the vertical direction and the left-right direction, the first shielding member and each of the conductors bend and extend downward from a top thereof and backward from a front thereof to be arc-shaped, each of the conductors comprises a first contact portion, a first conductive portion and a connecting portion connected to the first contact portion and the first conductive portion, and the first contact portions of the row of conductors located on the same one of the electrical modules are located on a same horizontal plane;
- wherein the row of conductors comprises a plurality of first grounding conductors and a plurality of pairs of first signal conductors arranged alternately along the left-right direction, and the two first signal conductors in a same pair of the pairs of first signal conductors have a same length;
- and wherein the first shielding member is electrically connected to at least one of the first grounding conductors, the first shielding member has a first main body portion located above at least one pair of the pairs of first signal conductors, and at least one first mating portion extends forward from the first main body portion;
- and
- a mating connector, configured to mate with the electrical connector, wherein the mating connector has an insulating body, a plurality of second grounding conductors and a plurality of pairs of second signal conductors arranged alternately on the insulating body, and at least one second shielding member fixed to the insulating body;
- each of the second grounding conductors and each of the second signal conductors in each pair of the pairs of second signal conductors has at least one second contact portion to be in contact with a corresponding one of the first contact portion, and a second conductive portion to be in contact with a circuit board and located in front of the second contact portion;
- the second shielding member is electrically connected to at least one of the second grounding conductors, the second shielding member has a second main body portion shielding above the pairs of second signal conductors, and a second mating portion extends backward from the second main body portion;
- wherein when the mating connector is inserted into the electrical connector and electrically connected to the pairs of first signal conductors, the second mating portion is electrically connected to the first mating portion, the second contact portion of each of the second signal conductors is electrically connected to the first contact portion of a corresponding one of the first signal conductors, and the second contact portion of each of the second grounding conductors is electrically connected to the first contact portion of a corresponding one of the first grounding conductors.
