Description

STRUCTURE FOR FIXING A COMA COIL OF DEFLECTION YOKE}

The present invention relates to a fixed structure of the coma coil bobbin mounted with the coma core of the deflection yoke. Specifically, the deflection yoke of the deflection yoke prevents the flow of the coma coil bobbin coupled to the deflection yoke so as to maintain the best quality of the cathode ray tube. It relates to a fixed structure of the coma coil to be mounted.

In general, the R (Red), G (Green), and B (Blue) electron beams 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. Since the light emitted by sealing each of the fluorescent surfaces mounted on the stripe causes light quality to be reduced across the television screen, it should be removed as much as possible to realize a normal image on the screen of the television.

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 sides are inclined inwardly with respect to the central axis. In the three electron beams, each of the electron beams must be designed to focus on the holes of the shadow mask and to 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. Sometimes.

In this case, the mislanding may be caused by 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 sarde beams.

These coma aberrations should be eliminated as much as possible, since they eventually become a source of deterioration over the entire television screen.

As shown in FIG. 1, the conventional deflection yoke is formed of a separator 110 having a bibular shape and a neck portion 120 formed at an upper side thereof, wherein the upper surface of the neck portion 120 of the separator 110 In order to eliminate the cause of the coma aberration according to the deflection characteristics, the coma coil 140 is used.

The coma coil 140 is a bobbin 142 having a rectangular shape to accommodate the core 141 having a substantially Korean consonant 'c' shape and the core 141, and the outside of the bobbin 142. It is composed of a coil 143 is wound a plurality of times on the periphery.

On the other hand, the neck 120, the protrusion formed on the upper surface is formed to be bent in a 'b' shape, and formed in a single line of the protrusion piece, the locking projection formed on the upper side and the locking jaw, the coma coil ( It consists of a support member 133 that supports the side and the bottom of the core 141 of the 140, the protruding piece, the engaging projection and the support member 133 is formed in proportion to the size of the coma coil 140.

The deflection yoke 100 having the configuration described above has a fixed structure protruding from the upper surface of the neck 120 of the separator 110, ie, fitting the coma coil 140 between the protruding piece, the locking protrusion, and the support member 133. To fix it.

However, according to the conventional deflection yoke 100, when the coma coil 140 is coupled to the upper surface of the neck 120, the flow of the coma coil 140 due to external shock or shaking is large, so that the deflection yoke 100 may be inclined. There was a drawback that greatly reduced the normal function.

Therefore, the main purpose of the present invention is to improve the fixing structure of the deflection yoke of the deflection yoke to more firmly combine the coma coil on the neck portion, the deflection yoke to prevent the flow of the core by the external shock or shake To provide a coma coil fixed structure of.

In order to achieve the above object, the deflection yoke's coma coil fixing structure bends the support member in a '-' shape on the upper surface of the neck so that the coma coil consisting of the core, bobbin, and coil can be fixed on the neck portion of the separator without flow. The coma coil of the deflection yoke formed by fixing means formed to protrude the locking member formed on the upper side of the support member in front of the support member and to support the side and the bottom of the coma coil toward the front of the locking jaw. In the fixed structure,

The technical features of the technical configuration is to form a mounting groove for receiving the mounting projections on the inner bottom of the support member of the fixing means protruding the mounting projection upward and the core bottom of the coma coil coupled to the fixing means.

When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention configured as described above are as follows.
