A connector assembly includes: a socket connector and a plug connector. The socket connector includes a main body having a tongue, multiple mating terminals, and a first thermal conduction member. The tongue has two first surfaces arranged opposite to each other. Each mating terminal has a first contact portion, and the first contact portions are exposed from at least one of the first surfaces. The first thermal conduction member has a first mating portion exposed from the at least one first surface provided with the first contact portions. The plug connector includes: a circuit board; a chip provided on the circuit board; a mating joint having an insulating body and multiple conductive terminals provided on the insulating body; and a second thermal conduction member provided on the insulating body. The second thermal conduction member has a second mating portion and a conducting portion thermally conducted with the chip.
