<P>PROBLEM TO BE SOLVED: To provide a power source plug of a novel structure exerting full noise-suppression effects, even in a high-frequency band. <P>SOLUTION: The power source plug is provided with plug-in blades 10, 11, connecting parts 20, 21, a grounding terminal 12, a plug housing 30 retaining these above, and a noise-suppressing means 40 housed in the plug housing 30. The noise-suppressing means 40 is provided with a magnetic core 400, a conductor 460 electrically insulated from the magnetic core 400, a grounding terminal 461 connected with the conductor 460, a coil 440 made by winding around coated wires 420, 430, and a dielectric 450 forming a capacitor together with the conductor 460 and the coil 440. Furthermore, one end each of the coated wires 420, 430 is connected to the plug-in blades 10, 11, while the other end is connected to outer terminals 20, 21; and the grounding terminal 461 is connected to a grounding metal fitting 30 which is grounded. <P>COPYRIGHT: (C)2010,JPO&INPIT |
