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.
Claims13
A horizontal deflection coil for a deflection yoke, comprising:
- a screen bent portion;
- a middle portion having a screen section portion for generating a main deflection magnetic field, the screen section portion including at least one wire curved-surface portion;
- and
- a neck bent portion,
- wherein a wire portion shaped in a letter ‘M’ or ‘W’ is piled centering on the wire curved-surface portion.

A vertical deflection coil for a deflection yoke, comprising:
- a screen bent portion;
- a middle portion having a screen section portion for generating a main deflection magnetic field, the screen section portion including at least one wire curved-surface portion;
- and
- a neck bent portion,
- wherein a wire portion shaped in a letter ‘M’ or ‘W’ is piled centering on the wire curved-surface portion.
2 more elements
A winder for a deflection yoke, comprising:
- a mold having a screen portion and a neck portion at a front side and a rear side thereof, and designed in a semiconical shape to form a portion where a deflection magnetic field of a deflection coil is generated;
- two or more turning pins protruded from the screen portion of the mold, for guiding a coil wire such that the deflection coil is formed having a predetermined shape;
- a cylindrical pin protruded from a winding portion of the mold, and having a screen section portion formed at a middle portion of the deflection coil, for correcting a magnetic field of a middle portion of the deflection coil;
- and
- an upward support pin protruded from the winding portion of the mold and pushing a wire portion piled by the cylindrical pin in a window direction such that the wire portion is formed having a predetermined thickness at a predetermined position.
