A connector module adapted for a set-top box including a shielding case, a first connector disposed outside of the shielding case, an annular capacitor disposed between the first connector and the shielding case, and at least one ferrite core disposed in the shielding case and generating mutual inductance by coupling the shielding case is provided. The first connector being connected to a peripheral cable has a transmission cable penetrating into the shielding case. The annular capacitor is electrically connected between a grounding layer of the transmission cable and a grounding of a first circuit board of the set-top box. The transmission cable is connected to a second connector of the first circuit board after entering the shielding case and penetrating the ferrite core. A high frequency signal from the peripheral cable is transmitted to the first circuit board via the first connector, the transmission cable, and the second connector.
