Title:
NOISE FILTER
Document Type and Number:
Japanese Patent JPS6027212
Kind Code:
A
Abstract:

PURPOSE: To mass-produce the titled noise filter and to reduce its production cost by winding up a pair of band-like magnetic conductors tubularly through band- like insulators such as insulating sheets and forming coils having distribution capacity from these magnetic conductors.

CONSTITUTION: Lead wires 7, 8 are connected to positions close to both the ends of a band-like magnetic conductor 6 such as iron foil and a lead wire 10 is connected to a band-like magnetic conductor 9. These two conductors 6, 9 are superposed through the band-like insulators 11 such s capacitor paper and wound up tubularly to form a noise filter element 12. Since a coil is formed between the lead wire 7 connected to the one end of the conductor 6 and the lead wire 8 connected to the other end and the conductor 6 forming the coil is sandwiched by the conductors 9, inductance is increased. In addition, a capacitor is formed like distributional constant as the whole, so that a noise suppressing effect can be displayed.
