The shielded coil which joints the center tap to the welding ground

摘要

Abstract Objective This invention to be suited for mass production, the effect of the electrostatic shieldingThe shielded coil which we have been able to have decided to obtain sufficiently is offered. Constitution Between primary coil P secondary coil S two seasrudo coil to have 2 and 3, as for polarity of the said shielded coil uncommonnessJointing the terminal 2b of one side of the ri and shielded coil 2 to the welding groundIt did, other terminal 2a made not yet joint. In addition, shielded volumeBelt 3 to joint coil terminal 3a to the welding ground, other terminal 3b is made not yet joint. As for two coils 2 and 3, common aThe shielded coil 1 which designates su as the center tap is.
