Patent number: 6369318Abstract: A radiant noise inhibiting assembly is constructed to inhibit a radiant noise in an electric cable connected to a digital type electronic device. The electric cable is covered by a substantially cylindrical magnetic structure which is constructed to act as a magnetic shield. A substantially cylindrical electrically conductive structure functioning as an electrostatic shield is disposed on the outside of the magnetic structure. Only a first end of the electrically conductive structure is connected to a ground of the electronic device, which first end is closer to the electronic device than a second end of the electrically conductive structure, which is not grounded. In this way, a portion of the radiant noise which is not completely absorbed by the substantially cylindrical magnetic structure is absorbed by the substantially cylindrical electrically conductive structure, thereby sufficiently inhibiting the radiant noise of the electric cable.Type: GrantFiled: February 17, 1999Date of Patent: April 9, 2002Assignee: Murata Manufacturing Co., Ltd.Inventors: Katsuyuki Uchida, Masami Sugitani, Yukio Sakamoto
