A shield plate inhibits high frequency noise generated by a circuit board from interfering with the operation of a jack connector. The jack and shield are mounted on a circuit board and the shield is connected to the shield plate and a common terminal of the jack. The shield plate is elastic and contains magnetic powder with a high flux density to interrupt high frequency noise coming from a direction of a circuit board. When mounted to a device chassis, the shield is connected to the chassis through resilient arms. The chassis, shield, shield plate and common terminal of the jack are all connected together and to a common ground. This configuration reduces incident noise received by the jack, without the need to modify the jack or circuit to optimize noise resistance.
