Connector module and set-top box

A connector module, adapted for a set-top box, the set-top box comprising a first circuit board, and the connector module comprising:

• a shielding case, for shielding high frequency RF signals;
• a first connector, disposed outside the shielding case, the first connector having a transmission cable penetrating the shielding case;
• an annular capacitor, disposed between the first connector and the shielding case, and electrically connected between a ground layer of the transmission cable and a grounding of the first circuit board;
• and
• at least one ferrite core, disposed in the shielding case and coupled to the shielding case to generate a mutual inductance,
• wherein the transmission cable penetrating the shielding case is electrically connected to a second connector of the first circuit board after penetrating the at least one ferrite core, and a high frequency signal of a peripheral cable adapted to dock the first connector is transmitted to the first circuit board through the transmission cable and the second connector.
