BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil separator of a deflection yoke, and more particularly, to a separator shape in which a coil mounted inside the separator is elastically adhered to the separator rib to improve cover displacement.

The coil separator provided in the deflection yoke is formed by combining two symmetrical components, and has a shape in which the vertical deflection coil and the horizontal deflection coil can be easily mounted on the inner and outer circumferential surfaces, respectively.

The coil separator of the deflection yoke can be roughly divided into a winding frame type and a bobbin type, and the winding frame type is a type in which the vertical coil and the horizontal coil are pre-wound in a specific shape by a separate coil winding device and then assembled to the coil separator. The bobbin type is a type in which vertical coils and horizontal coils are wound along the coil guides after integrally protruding a plurality of coil guides that can guide the coils to the inner side, the upper side, and the lower side of the screen portion. By the way, when the winding frame type coil separator is used, since the operation is convenient and the productivity is good, the winding frame type coil separator of the type of assembling the coil wound in a specific shape is generally used.

1 is a perspective view showing the shape of one assembly part of a conventional coil separator composed of two symmetrical assembly parts. As shown in FIG. 1, the shape of the conventional coil separator 1 is composed of two symmetrical structures, and a rib for checking the position at which the coil is attached and adhered at the boundary surface or the center of the two structures. ) Is installed. The coil attached to the inside of the coil separator has a convergence determined by the deflection value when the coil is closely attached to the rib, and therefore, the internal coil must be in close contact with the rib so that the correct deflection value can be calculated to obtain good convergence. However, in the assembling process, assembly scattering often occurs due to the case where the internal coil is not exactly matched to the ribs or the degree of proficiency of the assembler, and at this time, many additional processes are included to correct the deflection value. This ancillary deflection correction process may not only reduce productivity, but also cause side effects such as unexpected phenomena such as malfunction caused by the correction means. Therefore, in order to accurately calculate the calculated deflection value, it is important to assemble the inner coil so that it is in close contact with the ribs. There is a need to have a device that allows for natural close contact. However, looking at the methods for solving these problems, most of them are solved by a separate correction means.

SUMMARY OF THE INVENTION The present invention solves this problem of a conventional coil separator, and provides a separator shape that can accurately match a coil to a predetermined position of the separator, thereby reducing the injection dispersion of the separator itself, and also It aims to improve position accuracy and to reduce the scattering of assembly workers as a result of assembly, thereby preventing or minimizing convergence defects on the displayed screen.

In order to achieve this object, the present invention is provided by providing an elastic portion on the net side of the coil separator so that the coil mounted inside the separator by the elastic force of the elastic portion of the coil separator is elastically adhered to the rib of the separator. It provides a shape structure of the coil separator which makes the coil closely adhere to the rib.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a perspective view of one assembly part of the coil separator showing the overall shape of the coil separator having the cutout according to the present invention.

As shown in Fig. 2, the shape of the coil separator 1 is formed with a curved portion 11 whose radius decreases from the front portion 13 on the screen side to the rear portion 15 on the neck side. An incision 21 is formed in a portion near the rear part 15 in (11).

When looking at the shape of the cutout part 21, it cuts in a rectangular shape in the longitudinal direction of the coil separator, and the front part 13 side of the cutout part 21 is integral with the coil separator curved part 11 without being cut out. It is formed and fixed, the rear portion 15 is cut and configured to enter the inside by the longitudinal incision. The cut-out portion 21 recessed inside pushes the coil mounted therein by its elastic force to the inside, thereby bringing the inner coil into close contact with the rib of the separator.

Here, the cut portion of the incision portion is made toward the longitudinal direction and the rear portion of the separator, but this is a configuration for reinforcing the adhesion closer to the rear side portion, which is the most difficult to adhere when mounting the coil inside. Thus, various methods can be exemplified as a method of closely contacting the coil with ribs. That is, the cut portion may be configured by cutting only one side of the front portion, the rear portion and the side portion. In addition, although the elastic efficiency is inferior, it is also possible to make an incision by using the rear portion as a fixed portion. It is even possible to form a protrusion having a predetermined elasticity without making an incision.

In addition, the shape of the part to be cut is made into a square, but this is due to the ease of production, etc., can be configured in various forms.

Fig. 3 is a front view of one assembly part body of the coil separator showing the front shape of the coil separator having the cutout according to the present invention. As shown in Fig. 3, the cutouts provided in the coil separator generally constituted by the assembly of two structures are formed one by one on the side of the assembled cross section. Here, two cuts are formed on each side of the assembly end face, that is, on one side of the assembly, so as to elastically close the inner coil toward both sides of the rib 31. In addition, forming the cutout portion 21 on the end face of the assembly is to elastically close the inner coil toward the rib 31 more efficiently and more elastically. Of course, the position of the cutout 21 may be located in the middle of the rib 31 and the cross section, or may be formed closer to the rib 31.

Fig. 4 is a side view of one assembly part of the coil separator showing the side shape of the coil separator having the cutout according to the present invention. As shown in Fig. 4, the position of the cutout 21 is such that when the curved portion is divided into three portions 41, 43, and 45, the second portion 43 and the third portion 45 are placed. It is formed to an appropriate length. The location of the cutout is set as shown in Fig. 3 because the elastic adhesive force on the entire inner coil is the most efficient. However, since it is more difficult for the inner coil to be in close contact with the rib on the rear part 15 side, it is also preferable to position the position of the cutout part 21 in the third part 45.

In the above description of the configuration of the cutout, only one integral cutout is formed in the longitudinal direction of the separator. However, two or more integral cutouts may be formed in the longitudinal direction of the separator. On the other hand, in the case where two or more cutouts are formed, the positions of the cutouts are formed in the second part 43 and the other in the third part 45 as in the case of FIG. desirable.

The action of the cutout portion of the coil separator having the above configuration is as follows.

The cutout portion cut in the neck direction along the curved portion of the separator and elastically supported inwardly is pushed by the elastically from the curved portion in the axial direction of the separator when the coil is mounted therein. By this elastic force, the coil mounted in the inside comes in close contact with the rib of the separator. In particular, by forming a cutout on the neck side of the curved portion, the coil of the neck-side curved portion, which is more difficult for the coil to be in close contact with the rib, can be more easily in close contact with the rib side.

According to the coil separator having the cutout having the above structure and action, the coil can be closely adhered to the rib of the separator, and the error of the deflection value due to the injection scattering of the separator itself can be reduced by itself, and it is generated during assembly. It can absorb the scattering by the assembling worker itself, and as a result can prevent or minimize the convergence failure on the displayed screen. In addition, it is possible to greatly increase the production efficiency since there is no need for an additional device for the correction of the deflection value and the additional process.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to these embodiments, and has been claimed by those of ordinary skill in the art to which the invention pertains. It includes all variants of various forms that can be implemented without departing from the technical idea.
