Connector assembly with improved heat dissipation effect

A connector assembly, comprising:

• an electrical connector comprising an insulating body and a plurality of conductive terminals, the plurality of conductive terminals being configured to be mounted to a circuit board;
• a metal shielding cage shielding a periphery of the electrical connector;
• the metal shielding cage comprising a first end wall, a first side wall, a second side wall opposite to the first side wall, a second end wall opposite to said first end wall, and a receiving chamber jointly enclosed by the first end wall, the first side wall, the second side wall and the second end wall;
• the receiving chamber comprising a first receiving chamber configured to receive a first mating connector along a first direction, and a second receiving chamber configured to receive a second mating connector along the first direction;
• the first end wall defining a first opening communicating with the first receiving chamber;
• the second end wall defining a second opening communicating with the second receiving chamber;
• the first direction being perpendicular to the circuit board;
• and
• a heat dissipation element comprising a first heat sink and a second heat sink;
• the first heat sink comprising a first body portion fixed to the first end wall and at least partially protruding inwardly into the first opening, a plurality of first heat dissipation fins protruding sidewardly from the first body portion, and a plurality of first heat dissipation channels of which each is located between two adjacent first heat dissipation fins;
• the second heat sink comprising a second body portion fixed to the second end wall and at least partially protruding inwardly into the second opening, a plurality of second heat dissipation fins protruding sidewardly from the second body portion, and a plurality of second heat dissipation channels of which each is located between two adjacent second heat dissipation fins;
• the first body portion protruding inwardly into the first opening is configured to abut against the first mating connector;
• the second body portion protruding inwardly into the second opening is configured to abut against the second mating connector;
• wherein the circuit board defines a first heat dissipation slot extending through the circuit board and a second heat dissipation slot extending through the circuit board;
• the first heat dissipation slot communicates with the first heat dissipation channels along the first direction;
• and the second heat dissipation slot communicates with the second heat dissipation channels along the first direction.
