Description

FIXING STRUCTURE FOR COMA COIL OF DEFLECTION YOKE}

The present invention relates to the fixed structure of the deflection yoke, more specifically, to improve the assembly by improving the structure, and to prevent the flow of the coma coil, the deflection yoke of the deflection yoke to achieve the normal deflection characteristics It relates to a fixed structure.

In general, the deflection yoke deflects the electron beam emitted from the electron gun of the cathode ray tube to realize an accurate image.

At this time, the RGB electron beam emitted from the electron gun of the cathode ray tube is deflected at a predetermined angle by the deflection yoke and passes through the through-hole formed in the shadow mask, and is sealed to each stripe of the fluorescent surface mounted on the inner circumference of the panel. By emitting light, a normal image is realized on the screen of a television.

On the other hand, of the three electron guns of the cathode ray tube, the green electron gun in the center coincides with the center axis of the cathode ray tube, but the red and blue electron guns on the left and right are inclined inwardly with respect to the central axis. In this case, the three electron beams should be designed to focus on the holes of the shadow mask, respectively, and simultaneously reach the respective phosphors through the same holes.

In this case, the landing of the electron beam is precisely sealed to the inner circumference of the stripe of the panel is called landing. On the other hand, if the mis-landing occurs in which the electron beam deviates to the outer circumference of the stripe, the image of the screen is not cleared. .

Here, one example of the mislanding is a coma aberration caused by the deflection sensitivity with respect to the center beam being relatively stronger than the deflection sensitivity caused by the pair of side beams.

Since the coma aberration eventually causes deterioration of the picture quality over the entire television screen, the coma aberration is fixed to the upper surface of the neck portion of the separator to remove the coma aberration.

As shown in FIG. 1, the conventional deflection yoke 10 is formed of a separator 11 that is divided into approximately trumpets and has a neck portion at an upper side thereof. In this case, the upper surface of the neck portion 12 of the separator 11 is formed. In order to remove the cause of the coma aberration according to the deflection characteristics, the coma coil 20 is used.

The coma coil 20 includes a core 21 having a substantially Korean consonant 'c' shape, a bobbin 22 having a rectangular shape so as to embed the core 21, and the bobbin 22. It consists of the coil 23 wound by the outer periphery many times.

On the other hand, the neck portion 12 is formed in a straight line of the protrusion piece 13 protrudingly formed on the upper surface of the neck and bent in a '-' shape, and the protrusion piece 13, and the locking jaw 14a on the upper side. The molded protrusion 14 and the support member 15 for supporting the side and the bottom of the core 21 of the coma coil 20, the protrusion 13 and the protrusion 14 and the support The member 15 is arranged and formed in proportion to the size of the coma coil 20.

The deflection yoke 10 having the above configuration has a fixed structure protruding from the upper surface of the neck portion 12 of the separator 11, that is, the coma coil between the protruding piece 13, the locking protrusion 14, and the support member 15. (20) by fitting to be fixed.

However, according to the conventional deflection yoke, when the coma coil is coupled to the neck portion, the coma coil fixing structure formed on the upper surface of the neck portion is formed so tightly that its shape provides the worker with a deterioration factor for assembly, Due to the large flow of coma coil, the deflection yoke greatly reduced its normal function.

The present invention has been proposed to solve the above problems, and its purpose is to improve the structure of fixing the coma coil of the deflection yoke to facilitate assembling the coma coil on the neck portion and to improve the support structure of the core. It is to provide a fixed structure of the coma coil of the deflection yoke to prevent the up and down flow of the core by external impact or shaking.

The present invention for achieving the above object is in the coma coil fixing structure of the deflection yoke to fix the coma coil consisting of the core, bobbin and coil on the neck portion of the separator,

A rectangular locking means formed on an upper surface of the neck portion and having a locking jaw at an upper side thereof so that the upper surface of the bobbin is supported; Located in the front of the locking means, and supporting means for supporting the lower portion of the core; Located in the front of the support means, consisting of the support means for supporting the upper portion of the core is a technical feature of the technical configuration.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the drawings.
