Magnetic material filling for void spaces in deflection yokes

摘要

The invention relates to a deflection yoke (10) for a cathode ray tube (14) in which the energy for deflection is reduced. This is done by providing a magnetic material (56) in voids (52,54) that occur between the ferrite core (10) and a set of frame coils (18). The magnetic material (56) is comprised in a preformed insert (90), which may further comprise a rubber or plastic material. This results in a clean method of adding the magnetic material.
