A connector assembly includes a circuit board, a mounting bracket and a cable connector. The circuit board has a number of conductive pads. The cable connector includes an insulating body, a number of conductive terminals and cables. The insulating body includes a mounting surface. Each conductive terminal includes an elastic contact portion. The mounting bracket includes a frame portion and an installation space enclosed by the frame portion. The cable connector is at least partially received in the installation space so that the elastic contact portions are in contact with the conductive pads. Compared with the prior art, the present disclosure directly installs the cable connector on the circuit board by setting the mounting bracket, thereby omitting the socket connector and reducing the volume of the connector assembly.
