A plurality of first cables, wherein the plurality of first cables are electrically connected to the plurality of first conductive terminals; The second module includes: Second conductive housing; A second terminal module, at least partially disposed within the second conductive housing, comprising a plurality of second conductive terminals that do not contact the second conductive housing; each second conductive terminal includes a second contact arm, the second contact arm including a second contact portion; and A plurality of second cables, wherein the plurality of second cables are electrically connected to the plurality of second conductive terminals; The housing includes a first conductive housing and a second conductive housing, wherein the first conductive housing of the first module and the second conductive housing of the second module together form the receiving slot; the conductive terminal includes a first conductive terminal and a second conductive terminal; the cable includes a first cable and a second cable; and both the first contact portion and the second contact portion protrude at least partially into the receiving slot to make electrical contact with the mating connector.

21. The connector assembly as claimed in claim 6, characterized in that: The connector assembly further includes a heat dissipation module mounted on the shielding housing. The heat dissipation module includes a heat dissipation substrate and heat dissipation fins protruding from the heat dissipation substrate. The heat dissipation substrate at least partially protrudes into the receiving cavity. The heat dissipation fins protrude from the first tube portion and the second tube portion along a second direction. The first tube portion and the second tube portion are located on both sides of the heat dissipation fins along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.
