Description

Separator structure of deflection yoke

The present invention relates to a separator structure of a deflection yoke, and more particularly, an umbrella-type protective piece is provided at the top of a rib of a separator that partitions a first horizontal deflection coil and a second horizontal deflection coil that generate high frequency components. The present invention relates to a separator structure of a deflection yoke capable of realizing improved insulation and bearing capacity.

In general, a deflection yoke is a device for deflecting an electron beam emitted from an electron gun of a cathode ray tube, a vertical deflection coil deflecting the electron beam in a vertical direction, a horizontal deflection coil deflecting an electron beam in a horizontal direction, and the horizontal deflection coil and a vertical deflection coil. It consists of a separator that accurately distinguishes the positions of the deflection coils and at the same time electrically insulates them.

At this time, the electron beams of R (Red), G (Green), and B (Blue) emitted from the electron gun of the cathode ray tube are deflected at a predetermined angle by the deflection yoke and pass through the through holes formed in the shadow mask. By sealing the light on each stripe mounted on the inner circumference and emitting light, an image can be realized on a screen of a television.

A general deflection yoke performing the above function will be described with reference to FIGS. 1 and 2 as follows.

1 is a partially exploded perspective view illustrating a general deflection yoke, and FIG. 2 is a perspective view of a deflection yoke separator according to the prior art, viewed from the bottom.

As shown in FIGS. 1 and 2, the conventional deflection yoke 100 includes a separator 10 formed in a substantially trumpet shape, and a plurality of windings of the first and second vertical deflection coils 21 and 22, respectively. First and second ferrite cores 31, 32 mounted on the outer circumference of the separator 10, and first and second horizontal deflection coils 41 mounted on the inner circumference of the separator 10. , 42.

At this time, ribs 11 protrude in the longitudinal direction on both sides of the inner circumference of the separator 10 to form a substantially saddle shape as shown in FIG. The horizontal deflection coils 42 serve to partition each other.

On the other hand, since the first horizontal deflection coil 41 and the second horizontal deflection coil 42 have a shape that is tightly wound toward the rib 11, high frequency components, that is, 64 kHz high frequency components are The low frequency components of the first vertical deflection coil 21 and the second vertical deflection coil 22, that is, the low frequency components of the 60 Hz band, are adversely affected.

Therefore, the rib 11 should have a shielding function between the first horizontal deflection coil 41 and the second horizontal deflection coil 42, and the first horizontal deflection coil 41 and the second horizontal deflection coil. There must be a function to support 42 so that it can be mounted closely to the inner circumference of the separator 10.

However, in the separator structure of a conventional deflection yoke, ribs 11 which perform a function of shielding and supporting each other between the first horizontal deflection coil 41 and the second horizontal deflection coil 42 are provided on both sides of the inner circumference of the separator 10. Due to the protruding molding in the longitudinal direction, the first horizontal deflection coil 41 and the second horizontal deflection coil 42 perform only a function of simply partitioning each other, so that the shape is more tightly wound toward the rib 11 of the separator 10. The problem of failing to block the adverse effects of the high frequency components caused by the first horizontal deflection coil 41 and the second horizontal deflection coil 42, causing the temperature rise to greatly reduce the insulation effect, eventually, in the CRT There is a problem that the image quality on the television screen due to mis-landing of the emitted electron beam is greatly degraded.

Accordingly, the present invention has been devised to solve the above problems, and an object thereof is an umbrella type at the top of the rib of the separator that partitions the first horizontal deflection coil and the second horizontal deflection coil which generate high frequency components. It is to provide a separator structure of the deflection yoke that can be molded into a structure provided with a protective piece of maximizing the insulation effect and the supporting force.

Separator structure of the deflection yoke according to the present invention for achieving the above object, the deflection yoke separator structure comprising a rib-shaped trumpet-shaped separator for partitioning and seating at least the first horizontal deflection coil and the second horizontal deflection coil. The technical feature of the technical configuration of the present invention comprises a protective piece extending in both directions from an uppermost end of the rib to closely support the first horizontal deflection coil and the second horizontal deflection coil, and shielding mutual interference. It is done.

Hereinafter, a preferred embodiment of the separator structure of the deflection yoke according to the present invention will be described with reference to FIG. 3.

Figure 3 is a perspective view of the deflection yoke separator according to the present invention from the bottom, the same name and the same reference numerals will be used for the same configuration having the same function as the conventional configuration.

First, the deflection yoke includes first and second vertical deflection coils 21 and 22 for deflecting the electron beam in the vertical direction, and first and second horizontal deflection coils 41 and 42 for deflecting the electron beam in the horizontal direction. ) And the positions of the first and second horizontal deflection coils 41 and 42 and the first and second vertical deflection coils 21 and 22 can be precisely divided and electrically insulated from each other. It consists of a separator (10).

In this case, ribs 11 protrude in the longitudinal direction on both sides of the inner circumference of the separator 10 so as to partition the first horizontal deflection coil 41 and the second horizontal deflection coil 42 which form a substantially saddle shape. It will perform the function.
