Title: Device for preventing undesired radiation of magnetic field
Inventor: GOTO SUEHIRO
IPC: H05K9/00
Filed: 1991-03-08
Abstract: PURPOSE:To suppress leakage of a magnetic field from a deflection yoke of a display monitor not cancelled out by a cancel coil and a leakage magnetic flux radiating from a horizontal adjustment coil to an external device. CONSTITUTION:A protection tension band 8 is fitted to a front circumference of a cathode ray tube 4 in a cabinet of a display monitor, a metallic plate 9 is bridged between the protection tension band 8 and both sides of a bottom plate 2 to form a path for an eddy current in a loop by the band 8, the plate 2 and the metallic plate 9. When an ineffective magnetic flux or a leakage magnetic flux crosses the loop, an eddy current flows in the loop thereby suppressing a leakage magnetic field to the outside of the device. Thus, the leakage magnetic field at a horizontal deflection frequency is considerably reduced with simple structure and the device is inexpensively manufactured.
