A cable connector includes a housing, a terminal module and a cable connected to the terminal module. The terminal module includes multiple groups of conductive terminals. At least one group of conductive terminals include two signal terminals, a first ground terminal and a second ground terminal. The at least one group of conductive terminals include a connecting portion connecting the first ground terminal and the second ground terminal. The cable includes signal wires electrically connected to the signal terminals and a ground shielding layer wrapped around a periphery of the signal wires. The connecting portion is at least partially wrapped and fixed on the ground shielding layer. With this arrangement, it is easy to connect the ground terminals and the cable ground shielding layer in order to achieve a better shielding effect.
