Title:
NOISE ABSORBING EQUIPMENT
Document Type and Number:
Japanese Patent JP2733204
Kind Code:
B2
Abstract:
PURPOSE: To provide a noise absorbing equipment where a magnetic body is easily inserted into a holding case even if the size of the magnetic body is slightly scattered, and the magnetic body inserted once into the holding case hardly falls off.
CONSTITUTION: Engaging projections 24 and 26 are provided upright to a pair of cases 6 which contains a pair of ferrite cores 4 and 4 which are obtained by dividing a ring-shaped body in half in an axial direction to be engaged with engaging grooves 12 cut in the ferrite cores 4 so as to prevent the ferrite cores 4 from falling off the cases 6. The engaging projection 24 is provided to a displaceable wall 40 set displaceable by a pair of notches 38 provided spreading over a side wall 20 and an adjacent inclined wall 36. Therefore, when the engaging projection 24 comes into contact with the ferrite core 4, the projection 24 is so displaced by the elasticity of the displaceable wall 40 in a direction as to be less projected into a space where the ferrite core 4 is housed, so that the ferrite core 4 can easily be inserted into the case 6.
