Description

Technical Field Deflection yoke and empty picture tube device using the same

The present invention relates to a deflection yoke attached to a color picture tube (hereinafter, referred to as “CRT”) used for a television receiver or a computer display, and a CRT device using the deflection yoke. In particular, it relates to the structure of the deflection yoke. Background art

Conventionally, there is a so-called bend-up press type used as a self-convergence type deflection yoke mounted on an in-line type CRT. Hereinafter, the structure of the conventional shock absorber of the bent-up press type will be described. FIG. 1 is a schematic cross-sectional view schematically showing the structure of a deflection yoke of a conventional bend-up press type.

As shown in the figure, the deflection yoke 6 of the bend-up press type has a saddle-type horizontal deflection coil 11 attached along the inner peripheral surface of the insulating frame 13. It has a saddle-type vertical deflection coil 12 that is mounted along the surface between the light core 14 and the electron beam of the horizontal deflection coil 11 and the vertical deflection coil 12. The gun-side bend portion 17 (portion surrounded by a dotted line in the figure) has a structure substantially along the outer peripheral surface of the CRT funnel 4. In the figure, reference numeral 15 denotes a so-called VCR (vertical coma aberration) or side beam (R) which is provided on the outer peripheral portion of the electron lens 5 from the main lens portion 51 of the electron gun 5 in a direction slightly forward of the electron beam. , B) shows a correction coil that corrects the vertical misconvergence generated in (B), and 31 in the figure indicates a back cover, small cover, etc. for fixing the correction coil 15. (Hereinafter referred to as “back cover 31”), and their functions will be described later. In general, as the saddle-type deflection coil is located closer to the electron gun, the center of deflection is positioned closer to the electron gun, improving deflection sensitivity and deflecting the electron beam with low power. As a result, the deflection power can be saved as a result. The deflection yoke of the bend upless type is, for example, a deflection yoke of a conventionally used bend type, i.e., an electron gun side bend portion of a deflection coil is directed outward from the outer peripheral surface of the funnel. The deflection coil can be arranged closer to the electron gun side than the deflection yoke having a protruding structure, so the deflection sensitivity is higher than the deflection yoke of the above-mentioned bend-up type. And has the advantage that the deflection power can be saved. These are particularly effective in a high deflection angle CRT apparatus which has been widely used in recent years.Therefore, in a high deflection angle CRT apparatus, a bending up type deflection yoke is almost used. That is the current situation.

The bending yoke of the bend-up press type has the advantages described above, but the deflection yoke of the conventional bend-up type may cause inefficiencies in the manufacturing process due to its structure. There was a problem that there is.

That is, if the correction coil 15 is to be arranged above the electron gun side bend section 17 in the bending yoke of the bend-up pre-type, a member for fixing and positioning the correction coil 15 is provided by the electron gun. Must be provided so as to protrude greatly above side bend 17. Here, when the insulating frame 13 and the member to be protruded are to be integrally molded, when the deflection yoke is assembled, it is inserted into a gap between the protruding portion and the insulating frame 13. This is because the vertical deflection coils 12 must be installed, which makes assembly impossible or extremely inefficient.

Therefore, in the deflection yoke of the conventional bend-up press type, as a component for fixing and positioning the correction coil 15 while avoiding interference with the vertical deflection coil 12, FIG. Generally, the back cover 31 shown in Fig. 1 was used. Correction coil 15 is attached to back cover 31 in advance After the vertical deflection coil 12 is attached to the insulating frame 13, the correction coil 15 is fixed and positioned by being inserted from the electron gun side of the insulating frame 13. .

However, when a bending yoke of a bend-upless type is manufactured using the knock cover 31, the back cover 31 is required separately. There has been a problem that an increase in the number of processes for attaching the cover 31 is inevitable, and the production cost has to be increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and particularly when assembling a bend-up press-type deflection yoke, the assembly can be facilitated and the manufacturing cost can be reduced. It is an object of the present invention to provide a deflection yoke that can perform the above-described operation, and a CRT device using the deflection yoke. Disclosure of the invention

In the deflection yoke according to the present invention, the saddle-type horizontal deflection coil and the saddle-type vertical deflection coil are provided in an insulating frame that insulates the horizontal deflection coil from the vertical deflection coil. A deflection yoke provided along a peripheral surface and an outer peripheral surface, wherein a correction coil is provided at a position above an outer peripheral surface of an electron gun side bend portion of each of the deflection coils; An installation member is provided at a position behind the electron gun side bend portion on the electron gun side in a state where the positional relationship is fixed with respect to the insulating frame, and the correction coil is a screen of the installation member. The electron gun is provided at a position above the outer peripheral surface of the electron gun-side bend in a state of being positioned on a wall surface facing the fan.

According to this configuration, the correction coil can be easily mounted after the vertical deflection coil has been mounted on the insulating frame, so that the deflection yoke of the bend-up press type can be easily assembled. Becomes

Here, if the installation member is formed integrally with the insulating frame, it is not necessary to use a back cover which has been conventionally used. In addition to reducing the cost, the process of inserting the back cover is not required, so that the manufacturing cost of the deflection yoke can be reduced.

Further, if the correction coil is configured to be detachable from the installation member, it is convenient for maintenance when a failure occurs in the correction coil or each deflection coil. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a schematic sectional view showing an example of the structure of a CRT device to which the present invention is applied. In the CRT device 1 shown in the figure, a front panel 3 having a phosphor screen 2 formed on the inner surface and a funnel 4 constitute an envelope, and the inside of the network of the funnel 4 is formed. An electron gun 5 that emits an electron beam 7 is installed in the vehicle. The deflection yoke 6 according to the present invention is mounted on the neck of the funnel 4 along the outer surface of the funnel 4. FIG. 3 is a perspective view showing an example of the structure of the deflection yoke 6 in the present embodiment, and FIG. 4 is a longitudinal sectional view schematically showing the structure of the deflection yoke 6 (a side view is shown for the correction coil 15). ). The illustration of the CRT funnel 4, the electron gun 5, and the deflection yoke 6 of the X-light core 14 shown in FIG. 4 is omitted in FIG.

The deflection yoke 6 in this embodiment includes a saddle-type horizontal deflection coil 11 provided along the outer curved surface of the funnel 4 and a saddle-type horizontal deflection coil 11 provided outside the horizontal deflection coil 11. Dollar-shaped vertical deflection coil 12, insulating frame 13 that insulates horizontal deflection coil 11 from vertical deflection coil 12, and vertical deflection coil 1 2 includes a ferrite core 14 provided on the outside and a correction coil 15 provided on the outside of the main lens 51 of the electron gun 5 in the direction of the electron beam emission. The bend 17 on the electron gun side (portion surrounded by the dotted line in the figure) is a deflection yoke of a bend-upless type that has a structure almost along the outer peripheral surface of the CRT funnel 4. is there.

In the present embodiment, a flat plate 16 substantially parallel to the screen surface of the CRT device 1 is provided integrally with the insulating frame 13 at the rear side of the insulating frame 13 on the electron gun side. The screen surface side of the flat plate 16 (hereinafter, the forward side of the electron beam in the traveling direction is referred to as the “screen surface side”, and the opposite direction is referred to as the “electron gun side”. The term “rear part on the side of the gun” means that the correction coil 15 is fixed to the electron gun and is located closer to the electron gun than the tip of the electron gun 5). Has been established. The gist of the present invention is that the correction coil 15 is positioned on the screen surface side of the flat plate 16 as described above. In the present embodiment, the insulating frame 13 and the flat plate 16 are integrally formed. This makes it possible to reduce the number of parts, which is suitable for reducing the manufacturing cost.However, the insulating frame 13 and the flat plate 16 are formed as separate members, and the correction coil is used. Prior to mounting 15, for example, both may be assembled before mounting the vertical deflection coil 12. This is because, even in such a case, the effect of facilitating the manufacture of the deflection yoke 6 can be obtained as compared with the related art.

In the present embodiment, the correction coil 15 is fixed upward and downward as viewed from the screen surface, and the correction coil 15 is fixed from the flat plate 16 to the electron gun side bend portion 17. It is provided so as to protrude on the outer peripheral surface, and is detachably fixed to the flat plate 16.

FIG. 5 is a three-view drawing showing an example of the structure of the correction coil 15 in the present embodiment. The correction coil 15 is composed of a U-shaped core 22 made of a flat body with both legs directed toward the electron gun-side bend 17, and a pobin mounted at the center of the bottom of the U-shaped core 22. 23, a pair of flanges 25 provided at both ends of the bobbin 23, and fixing members 26 fixed to both ends of the bottom of the U-shaped core 22. To configure the correction coil 15 In FIG. 5, a conductor (not shown) is wound. In the present embodiment, the fixing member 26 is formed of plastic, and fixed with the U-shaped core 22 and an adhesive.

Returning to FIG. 3, in the correction coil 15 according to the present embodiment, the brim portion 25 abuts on the screen side surface of the flat plate 16, and the correction coil 15 extends from the flat plate 16. In addition to defining the distance, the claw 27 provided at the tip of the fixing member 26 is engaged with the rectangular cutout 28 provided at the edge of the flat plate 16. Thus, the correction coil 15 and the flat plate 16 are fixed. FIG. 6 is an enlarged view of a portion where the notch portion 28 and the claw portion 27 are engaged. In the present embodiment, the positioning of the correction coil 15 is facilitated by providing the brim portion 25. However, depending on the material of the fixing member 26, the claw portion 27 and the notch portion 2 are provided. In some cases, it is possible to position the correction coil 15 by engagement with the shaft 8, and in such a case, it may be unnecessary to provide the collar 25.

The correction coil 15 in the present embodiment has a U-shaped ferrite core 22 wound with a conducting wire 24 as shown in FIG. 7, and generates a six-pole magnetic field synchronized with vertical deflection. It is used to optimally correct the VCR whose pattern is shown in Fig. 8, and to further wind another wire and control the magnetic field generated by that wire, thereby making the same core 22 4 poles It has the function of generating a magnetic field and compensating for the longitudinal misconvergence of the side beams (R, B) whose pattern is shown in FIG. Since the operation of the correction coil 15 itself is already known, a detailed description thereof will be omitted, but it is possible to configure the correction coil 15 so as to correct both the VCR and the vertical misconvergence. Alternatively, it may be configured to correct only one of them.

At first, as the correction coil 15, as shown in FIG. 10, an E-shaped ferrite core 29 having a leg 24 wound around each leg thereof may be used. Wear. When such an E-shaped core 29 is used, as shown in FIG. 11, an example of the structure is provided with the correction coils 15 on the right and left sides when viewed from the screen surface. It is preferable to do so. Again, different By controlling the magnetic field by winding a conductive wire around the same light core 29, the correction coil 1 that corrects the longitudinal misconvergence of the VCR and the side beams (R, B) respectively. 5 can be configured in the same manner as the case where the character-shaped core 22 is used.

Further, as shown in FIG. 12, the U-shaped core 22 and the I-shaped core 30 may be combined to form the correction coil 15. In this case, for example, a correction coil 15 can be attached as shown in FIG. 13 as an example of the structure.

As described above, the structure in which the notch portion 28 is provided on the side surface portion of the flat plate 16 and is engaged with the claw portion 27 is the same as the deflection yoke 6 according to the present invention. 5 is merely an example of a structure for mounting on the flat plate 16 and various other mounting methods are conceivable. For example, as shown in FIG. 14, an insertion hole 31 is provided in the flat plate 16, and a claw portion 27 provided at a distal end portion of the fixing member 26 is provided in an inner peripheral portion of the insertion hole 31. Alternatively, the notch 28 may be engaged. FIG. 15 is an enlarged view of the vicinity of the inlet hole 31 when the inlet hole 31 is provided. It is also conceivable to insert the distal end portion of the fixing member 26 into the insertion hole 31 without providing the claw portion 27, and to use the flat plate 16 instead of the insertion hole 31. It is also possible to fix the correction coil 15 by providing a slit in the slit and attaching a fixing member 26 to the slit.

In addition, the provision of the claw portion 27 and the like, and the configuration in which the correction coil 15 and the flat plate 16 are attached and detached independently, means that, for example, a failure such as a correction coil 15 or a deflection coil occurs. It is convenient for maintenance of the CRT device in that it is possible to replace only one of them in the case of the above, but the present invention is not limited to the above. It is also possible to adopt a configuration in which an adhesive is used for bonding to the device. Even so, the effect of facilitating the manufacture of the deflection yoke is obtained.

Furthermore, even when the I-shaped core 30 is not used as shown in FIG. 13, the correction coil 15 is mounted on the flat plate 16 as shown in FIG. If the part to be formed is narrower than the other parts, the material used for forming the flat plate 16 can be saved, and the overall size of the flat plate 16 is better than that shown in the figure. It is of course possible to make it small. It should be noted that the various modifications as described above can be performed in any case, such as when the E-shaped light core 29 is used or when the I-shaped core 30 is used together. It goes without saying that the same can be applied.

Next, an embodiment in which the present invention is applied to an in-line type CRT device for a 46 [cm] (19 inch), 100 degree deflection type display will be described.

The Z axis is the direction of the tube axis of the CRT, the positive direction is the direction toward the screen surface, and the position of the rear end of the horizontal deflection coil 11 and vertical deflection coil 12 on the electron gun side is Z. = 0. Assuming that the electron gun side bend 17 of the vertical deflection coil 12 is located in the range of Z = 0 to 8 [mm], the plane plate 16 has a thickness of, for example, 2 [mm]. , Z = _ 2 to 0 [mm]. By fixing the correction coil 15 in the range of Z = 2 to 4 mm, the correction coil 15 is disposed above the electron gun-side bend 17. It will be.

As described above, by using the deflection yoke of the present invention, the deflection yoke of the bent-up press type can be easily assembled. In addition, if the insulating frame 13 and the flat plate 16 are integrally formed, a separate member from the insulating frame 13 required for the deflection yoke of the conventional bent-up type is required. It is possible to provide the same function of fixing the correction coil as before without using the back cover. Also, by adjusting the size of the fixing member 26 and the brim portion 25, the correction coil 15 can be installed at an arbitrary position.

In the above-described embodiment, the flat plate 16 is used as a member for fixing the correction coil 15. However, this is not limited to the flat plate. Any shape can be used as long as it can be fixed in position.

In the above embodiment, the core 22 of the correction coil 15 and the fixing member 26 is bonded with an adhesive, but various modifications are also conceivable. For example, a fixing member 26 and a brim portion 25, a bobbin 23 and the like are integrally formed with a component and a flange.補正 The correction coil 15 can also be made from a light core, conductor, etc.

Further, in the above embodiment, the case where the present invention is applied to the bending type of the bent-up press type has been described in detail, but the scope of the present invention is limited to the bending yoke of the bend-up type. However, if the method of the present invention is used, the correction coil can be arranged on the screen side of the flat plate even in the bend-up type deflection yoke. This is effective when you do not want the magnetic field of the coil to leak into the electron gun.

Further, the scope of application of the present invention is not limited to the deflection convergence of the self-convergence method. It is conceivable that a deflection coil other than the self-convergence method needs to be provided with a correction coil at the bend portion of the deflection coil on the electron gun side.In such a case, the method of the present invention cannot be applied. Because it is possible. Therefore, the correction coil 15 is not limited to the one that corrects the vertical Misconvergence of the VCR and the side beam, and can be applied to various correction coils.

The deflection yoke and the CRT device of the present invention are particularly applicable to a television receiver or a computer display using a CRT device having a high deflection angle.
