Problems solved by technology

Therefore, there is a defect that scattering occurs during the manufacturing process, whereby the shape of the wire portion 43 is not maintained, and variations are generated
[0035] In addition, due to the above drawbacks, the horizontal deflection coil 12 is suspended in the pressing direction (direction of the arrow), thereby causing the middle portion 12b of each product to have a different shape when the products are manufactured.
Therefore, there is a defect that in the two horizontal deflection yokes installed in the deflection yoke, the four intermediate portions have different shapes, thereby not generating the same deflection magnetic field, thus causing misconvergence due to scattering during the manufacturing process
In addition, there is also the fact that each product generates a different deflection magnetic field, thereby resulting in damage to product quality

Abstract

Provided is a horizontal deflection coil of a deflection yoke in which the shape of the horizontal deflection coil is changed, thereby adjusting a screen wire distribution regardless of a middle wire distribution and constantly maintaining the shape of the middle portion of the horizontal deflection coil.

Description

technical field [0001] The present invention relates to a horizontal deflection coil applied to a deflection yoke, and more particularly, to changing the shape of the horizontal deflection coil to deflect the horizontal deflection coil of the yoke, thereby adjusting screen wire distribution, and Regardless of middle wire distribution. Background technique [0002] Typically, cathode ray tubes in televisions use electronic deflection technology. To irradiate electron beams, it is basically required to apply horizontal and vertical magnetic fields from the neck of the cathode ray tube. The two coils placed basically at a 90 degree angle to form these deflection magnetic fields are called "horizontal and vertical deflection yokes", and the combination of the deflection coils and ferrite core is called a "deflection yoke". [0003] The deflection yoke can be divided into three types, that is, a saddle type in which two deflection coils are designed with a saddle-shaped oblique...
