The present invention relates to a deflection yoke, and more particularly, to a peripheral part mounting structure of a deflection yoke for mounting a peripheral part such as a correction piece, a circuit board, and a magnetic field offset coil.

Generally, the deflection yoke used for a TV receiver or a monitor is horizontal inside the coil separator 13 which consists of the neck part 11 and the screen part 12, as shown to FIG. 1 (a) (b). A deflection coil (not shown) is coupled, and a ferrite core 15 wound around a vertical deflection coil 14 is assembled to the core clamp 16.

Further, on both sides of the upper face of the neck portion 11 of the coil separator 13, a correction piece 18 having a coil 17 wound thereon is attached to correct the misconvergence, and one side of the neck portion 11 has horizontal and vertical deflection coils. A circuit board 19 is attached to the power supply 14 so that the leakage magnetic field offset coil 21 is disposed on one side of the screen unit 12 to offset the leakage magnetic field generated by the horizontal and vertical deflection coils 14. The wound leakage magnetic offset device 20 is formed.

Such a deflection yoke has red (R) and green (G) radiated from an electron gun by generating a magnetic field as a sawtooth pulse is applied to the horizontal deflection coil and the vertical deflection coil 14 wound inside and outside the coil separator 13. ), The position of the blue (B) electron beam is determined.

However, in such a conventional deflection yoke, assembling and assembling the correction piece 18, the circuit board 19, the leakage magnetic field offset coil 21, and the like, which are peripheral parts, respectively, has caused the inconvenience of assembly and the deterioration of workability. In particular, errors due to the mechanical mechanism of the deflection yoke and characteristic errors due to assembly dispersion are generated, which leads to a problem in that the reliability of the product is significantly reduced.

The present invention was devised to solve such problems in the related art, and it is very easy to combine the peripheral parts attached to the deflection yoke, and in particular, the peripheral part mounting structure of the deflection yoke, which can improve workability and reduce cost The purpose is to provide.
