The vertical deflection coil 3 includes an enlarged portion 3A on the neck side and an enlarged portion 3B on the face side.

The deflection yoke device having such a configuration usually requires a circuit for correcting deflection characteristics, and a substrate 5 having such a circuit mounted thereon is mounted on the side surface of the separator 1. Since a high voltage is applied to the circuit of the substrate 5, the substrate 5 is covered with a protective cover 6 made of an insulating material for preventing electric shock and protecting the circuit and the like. A plurality of claws 6a are formed on the protection cover 6, and the protection cover 6 is attached to the substrate 5 by the plurality of claws 6a. In FIG. 18, the protective cover 6 is shown in cross section, and in FIG. 19, the protective cover 6 is omitted.

[0007] A plurality of flanges 1a1, 1a2, 1a3 (hereinafter referred to as neck side flanges) 1a are provided on the neck side of the separator 1, and flanges (hereinafter, face side flanges) are provided on the face side. 1)
b is provided. A four-pole correction coil 7 called a pair of 4P coils is fitted on the neck-side flange 1a1 of the neck-side flange 1a. The correction coil 7 is for correcting a frame error called VCR.

[0008] A claw 8 for mounting the substrate 5 on the separator 1 is provided on the flange 1a3 closest to the face by integral molding. A hole (not shown) is formed in the substrate 5, and a claw 8 provided on the flange 1a3 is engaged with the hole. On the other hand, face side flange 1
In b, a pair of plate-shaped ribs 9 are provided by integral molding. The substrate 5 is held with its lower end sandwiched between a pair of ribs 9. In this manner, the substrate 5 is attached to the side surface of the separator 1 by the claws 8 and the ribs 9 provided on the flange 1a3.

Further, a plurality of pins 10 as terminals for connecting lead wires are press-fitted into the substrate 5, and these pins 10 are connected to the lead wires 2a of the horizontal deflection coil 2 and the vertical deflection coils 3 respectively. The lead wire 3a and the lead wire 7a of the correction coil 7 are entangled. To supply current to the deflection yoke device, a connector wire 12 is connected to a connector 11 connected to a power supply, and a lead wire 12 a of the connector wire 12 is also wrapped around the pin 10 of the substrate 5. Note that the connector wires 12 penetrate the board 5 and are wired to the pins 10.

Then, the pins 10 and the lead wires 2a, 3a,
7a and 12a are electrically and mechanically connected to the substrate 5 by soldering. The protective cover 6 is mounted on the board 5 after the connection of the lead wires 2a, 3a, 7a, 12a to the board 5 is completed. The solder is not shown here.

The substrate 5 is provided with a correction coil 13 (hereinafter, referred to as a differential coil 13) for correcting misconvergence described later. Differential coil 13
Is a bobbin 13a having a cylindrical hollow portion 13a1, a core 13b (hereinafter referred to as a screw core 13b) having a screw formed on the outer peripheral surface and mounted in the bobbin 13a, and a pair wound around the bobbin 13a. And the coil 13c.

At the longitudinal end of the differential coil 13 (bobbin 13a), an elastic claw 13d is provided by integral molding. The differential coil 13 is attached to the board 5 by engaging a claw 13 d with a hole (not shown) provided in the board 5.

Now, the operation of the differential coil 13 will be described.

G is a green line.

Next, the substrate 5 of the lead wires 2a, 3a, 7a
The wiring to the pin 10 will be described. The correction coil 7 is connected to a circuit on the vertical deflection coil 3 side. As you know,
Only a voltage of about several volts is applied to the vertical deflection coil 3,
Since a voltage of about 1 kV is applied to the horizontal deflection coil 2, a high potential difference occurs between the horizontal deflection coil 2 and the vertical deflection coil 3. Therefore, it is necessary to secure a predetermined creepage distance or space distance between the lead wire 7a of the correction coil 7 and the lead wire 2a of the horizontal deflection coil 2 for insulation.

Therefore, the lead wire 7a of the correction coil 7 is
It passes between the flanges 1a1 and 1a2 of the neck side flange 1a,
Connect the lead wire 2a of the horizontal deflection coil 2 to the neck side flange 1
By passing between the flanges 1a2 and 1a3 of a, the two are separately wired. Thereby, the pipe axis direction between the flanges 1a1 and 1a3 of the neck side flange 1a (vertical direction in FIG. 18)
Is small, but it is possible to easily secure a necessary creeping distance between the lead wire 2a and the lead wire 7a.

The lead wire 3a of the vertical deflection coil 3
Are wired to the pins 10 for the vertical deflection circuit provided at a position sufficiently distant from the horizontal deflection circuit among the pins 10 of the substrate 5.

Further, when a voltage of as much as 1 kV is applied between the terminals A and B in FIG. 20, the electric resistance of the horizontal deflection coil 2 is much higher than that of the differential coil 13, so that the horizontal deflection coils 2 ₁ and 2 _A very high potential difference occurs between the _two ends (between C and D and between E and F).

[0019] Therefore, as shown in FIG. 19, the separator 1 horizontal deflection coil 2 _1, 2 ₂ of the winding-start wire 2 _1S, 2 _2S
The upper half (α side) flange 1a2, 1a3
Together passed between, wiring to pass horizontal deflection coil 2 _1, 2 ₂ of the winding end wires 2 _1F, 2 _2F between the flanges 1a2,1a3 half of the lower side in the figure of the separator 1 (beta side). Note that the lead wires 2a, is a general term of the winding-start wire 2 _1S, 2 _2S and the winding end wire 2 _1F, 2 _2F. by this,
The required creeping distance between the winding start side and the winding end side of the lead wire 2a of the horizontal deflection coil 2 is ensured.

The vertical deflection coil 3 is applied only with a voltage that the insulating layer covering the electric wire of the vertical deflection coil 3 can withstand. Therefore, the winding start line and winding end line of the vertical deflection coil 3 are described above with respect to the horizontal direction. There is no need to provide an insulation distance as in the case of the deflection coil 2. Also, as shown in FIG. 18, since the lead wire 3a of the vertical deflection coil 3 is wired to the pin 10 located sufficiently away from the pin 10 for wiring the lead wire 2a of the horizontal deflection coil 2, the horizontal deflection There is no short circuit between the coil 2 and the vertical deflection coil 3.

[0021]

In recent years, the demand for ultra-high-definition displays has been increasing, so that deflection yoke devices have higher quality than before, that is, have excellent convergence performance. Is required. Therefore, there has been proposed a deflection yoke device provided with a correction coil for correcting a misconvergence in which a red line and a blue line are shifted in the horizontal direction at left and right ends of a screen, which is called XH misconvergence. Examples thereof include those described in Japanese Patent Application Laid-Open No. Hei 7-162880, the prior application by the present applicant who has further improved this, and Japanese Patent Application No.
No. 11403 or Japanese Patent Application No. 10-13398.

Here, XH misconvergence will be described. FIGS. 22A and 22B show XH misconvergence caused by variations in the horizontal deflection magnetic field. FIG. 22 (A) is a pin cushion misconvergence pattern of the X (horizontal) axis generated when the horizontal deflection magnetic field pincushion is too strong, and FIG. 22 (B) is because the horizontal deflection magnetic field pincushion is too weak. It is a barrel misconvergence pattern of the generated X-axis. Note that the solid line indicates a vertical bright line of R (red) and the broken line indicates a bright line of B (blue).

FIG. 23 shows an example of a circuit for correcting XH misconvergence. In FIG. 23, the same portions as those in FIG. 20 are denoted by the same reference numerals. In FIG. 23, an XH misconvergence correction circuit 14 is provided between the differential coil 13 and the terminal B. The horizontal deflection coil 2 and the XH misconvergence correction circuit 14 are connected in series via a differential coil 13. The XH misconvergence correction circuit 14 includes a pair of auxiliary deflection coils 15 connected in parallel, and a variable inductance coil 16 connected in parallel to the auxiliary deflection coils 15.

The variable inductance coil 16 is configured as follows, for example. In FIG. 24, a variable inductance coil 16 includes a bobbin 16a having a cylindrical hollow portion 16a1 formed of an insulating material such as a plastic resin, and a core 16b having a thread formed on an outer peripheral surface and mounted in the bobbin 16a. (Hereinafter, referred to as a screw core 16b) and a coil 16c wound around the bobbin 16a.

In the variable inductance coil 16 configured as described above, the inductance of the coil 16c can be freely adjusted by moving the screw core 16b in the longitudinal direction of the bobbin 16a. And
By adjusting the inductance of the variable inductance coil 16, the current flowing through the auxiliary deflection coil 15 in FIG. 23 is changed, and the XH shown in FIGS. 22 (A) and (B) is changed.
Correct misconvergence.

The position where the auxiliary deflection coil 15 is provided is the inner peripheral portion of the horizontal deflection coil 2 as proposed by the present applicant in Japanese Patent Application No. 9-212403 or Japanese Patent Application No. 10-13398. In the range from the window to the outer peripheral portion, the horizontal deflection coil 2
It is desirable to wind between them.

The deflection yoke device provided with the XH misconvergence correction circuit 14 as described above is different from the conventional deflection yoke device not provided with the XH misconvergence correction circuit 14 in terms of the components mounted on the deflection yoke device. Since the number of correction coils) is increased, it is an important factor in designing the deflection yoke device how and where the differential coil 13 and the variable inductance coil 16 are mounted in the deflection yoke device.

For example, depending on the position where the variable inductance coil 16 is mounted, the variable inductance coil 1
6 and the horizontal deflection coil 2 or the vertical deflection coil 3 may be short-circuited. Therefore, it is necessary to give sufficient consideration to the position where the variable inductance coil 16 is mounted.

Further, depending on the position where the variable inductance coil 16 is mounted, the variable inductance coil 16 and the horizontal deflection coil 2 and the vertical deflection coil 3 are made large in order to avoid a short circuit between the horizontal deflection coil 2 and the vertical deflection coil 3. It becomes necessary to separate them, and the deflection yoke device becomes extremely large. Further, the variable inductance coil 16
Depending on the mounting position, it may be difficult to adjust the deflection characteristics.

As described above, in order to put the deflection yoke device provided with the XH misconvergence correction circuit 14 into practical use, it is necessary to mount the variable inductance coil 16 at an optimum position. Not done.

The present invention has been made in view of such a problem, and has an auxiliary deflection coil connected in series with a horizontal deflection coil, and corrects a current flowing through this auxiliary coil to correct misconvergence. It is an object of the present invention to provide a deflection yoke device having a coil, which does not cause a short circuit with another coil. Also,
It is an object to provide a deflection yoke device that can be miniaturized as much as possible. It is another object of the present invention to provide a deflection yoke device in which the deflection characteristics can be easily adjusted.

The case where the coils 16 are respectively mounted at the illustrated positions is shown.

In FIGS. 15 to 17, the right side in FIG.
The left side in the figure is the α side shown in FIG. 9, and the β side shown in FIG. In the example shown in FIG. 19, the α side and the β side correspond to the two halves of the separator 1. However, the α side referred to in the present application means the variable inductance coil 16 of the lead wire 2a of the horizontal deflection coil 2. means a side on which the potential difference is routed to the winding-start wire 2 _1S, 2 _2S is a small side of the lead wire, the β side referred to in the present application, among the leads 2a of the horizontal deflection coil 2, the variable inductance coil the potential difference between the 16 means the side that routed the winding end wire 2 _1F, 2 _2F is a larger side of the lead wire.

Therefore, the α side and the β side may not correspond to each of the two halves of the separator 1. Furthermore, the separator 1 is not composed of two halves,
Even in the case of an integral separator that is not divided,
There is the concept of the β side.

As shown in FIG. 15, the variable inductance coil 16 is connected to the winding end line 2 _1F of the horizontal deflection coil 2,

Assuming that the variable inductance coil 16 is directly attached to the face side flange 1b as shown in FIG.
Since it is necessary to provide a predetermined spatial distance between the variable inductance coil 16 and the vertical deflection coil 3, the variable inductance coil 16 must be attached to the face side flange 1b in a state of protruding outward.
