Description

Horizontal deflection coil fixing structure of deflection yoke

The present invention relates to a horizontal deflection coil fixing structure of the deflection yoke, and more particularly, a plurality of injection holes formed through the injection molding to inject hot melt from the outer circumference of the separator to the inner circumference of the flange and the coil spacer. It relates to a horizontal deflection coil fixing structure of the deflection yoke capable of closely bonding between the horizontal deflection coil and the coil spacer mounted on the inner circumference of the separator.

Generally, the deflection yoke 100 is a device for deflecting an electron beam emitted from an electron gun of a cathode ray tube, as shown in FIG. 1, a horizontal deflection coil 110 deflecting an electron beam in a horizontal direction, and the electron beam in a vertical direction. A deflecting vertical deflection coil (not shown) and a separator 120 for precisely distinguishing the positions of the vertical deflection coil and the horizontal deflection coil 110 and being electrically insulated from each other.

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 100 and pass through the through holes formed in the shadow mask. It is possible to realize an image on a screen of a television by sealing light on a stripe of each fluorescent surface mounted on an inner circumference of a panel.

Here, the separator 120 for precisely distinguishing the positions of the vertical deflection coil and the horizontal deflection coil 110 and being electrically insulated from each other, the neck portion to which the cathode ray tube is coupled as shown in FIG. And a coil spacer 122 for mounting the horizontal deflection coil 110 and the vertical deflection coil on the inner and outer circumferences thereof, and a flange part 123 closely attached to the rear surface of the CRT.

Meanwhile, the vertical deflection coils and the horizontal deflection coils 110 mounted on the inner and outer circumferences of the coil spacer 122 respectively perform a function of deflecting the R, G and B electron beams emitted from the electron gun of the cathode ray tube at a predetermined angle. However, a deflection angle is shifted depending on the mounted state or the wound shape, resulting in reverse crossover and misconvergence.

In order to overcome this problem, the horizontal deflection coil 110 should be mounted on the inner circumference of the coil spacer 122 as closely as possible. Conventionally, the horizontal deflection coil 110 is mounted on the inner circumference of the coil spacer 122. Since it can be simply fixed by its own elastic force due to the external shock and shaking, its position is changed, there is a big disadvantage that the mismatch of convergence and distortion of the pincushion occurs.

That is, there is a big problem that the quality of the image on the television screen is greatly deteriorated by causing mis-landing of the electron beam emitted from the cathode ray tube due to the poor fixing of the horizontal deflection coil 110.

Therefore, the present invention is devised to solve the above problems, and its purpose is to form a through-melt to inject hot melt from the outer periphery of the separator toward the inner periphery of the boundary between the flange portion and the coil spacer. It is to provide a horizontal deflection coil fixing structure of the deflection yoke, which is provided with a plurality of injection holes to closely bond the horizontal deflection coil and the coil spacer mounted on the inner circumference of the separator.

The present invention for achieving the above object is a deflection comprising a separator consisting of at least a neck portion to which the cathode ray tube is coupled, a coil spacer for mounting the horizontal deflection coil to the inner circumference, and a flange portion closely attached to the rear side of the CRT. In the yoke horizontal deflection coil fixing structure, a plurality of injection holes are formed through a plurality of injection holes formed at the boundary between the flange portion and the coil spacer so as to inject hot melt from the outer circumference of the separator toward the inner circumference. It is a basic characteristic on configuration.

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

Figure 3 is a perspective view showing a separator applied to the horizontal deflection coil fixing structure of the deflection yoke according to the present invention, the same name and the same reference numerals will be used for the same configuration having the same function as the conventional configuration.

The deflection yoke 100 according to the present invention includes a horizontal deflection coil 110 for deflecting the electron beam in a horizontal direction, a vertical deflection coil deflecting the electron beam in a vertical direction, the vertical deflection coil and The separator 120 is configured to precisely classify the position of the horizontal deflection coil 110 and to be electrically insulated from each other.

At this time, the separator 120 is in close contact with the neck portion 121 to which the cathode ray tube is coupled, the coil spacer 122 for mounting the horizontal deflection coil 110 and the vertical deflection coil to inner and outer circumferences, and the rear surface of the CRT. It consists of a flange portion 123 to be mounted.

In addition, a plurality of injection holes 130 are formed in the boundary between the flange portion 123 and the coil spacer 122 so that hot melt may be injected from the outer circumference of the separator 120 toward the inner circumference.

Here, the hot melt injected through the plurality of injection holes 130 performs the function of closely bonding the horizontal deflection coil 110 and the coil spacer 122 mounted on the inner circumference of the separator 120 to impact externally. And it can be seen that it is possible to prevent the positional change and shaking of the horizontal deflection coil (110) due to shaking to overcome the deterioration of the image quality due to the fixing failure of the horizontal deflection coil (110).

As described above, according to the horizontal deflection coil fixing structure of the deflection yoke according to the present invention, a plurality of injection holes are formed through the injection molding so that hot melt can be injected from the outer circumference of the separator to the inner circumference of the flange and the coil spacer.
