[Industrial use]

The present invention relates to a deflection yoke separator. More specifically, a fixed receiving end may be used to fix a spacer for maintaining a pair of vertical deflection coils at a constant interval from each other, and a magnetic leakage preventing structure may be combined with a strong clamping force. One deflection yoke separator.

[Prior art]

In general, the deflection yoke applied to the cathode ray tube is arranged with a horizontal deflection coil for deflecting an electron beam to be scanned with an electron gun in a horizontal direction inside a separator formed by a combination of a half-trumpet-shaped resin material. On the outside, a pair of vertical deflection coils forming a deflecting magnetic field in the vertical direction to the electron beam is arranged.

However, when the pair of vertical deflection coils are in contact with each other or disposed closer than necessary, the pair of vertical deflection coils may interfere with each other to form an even deflection magnetic field.

Therefore, by assembling and assembling a spacer for maintaining a constant gap between the pair of vertical deflection coils, the function of each other is not disturbed.

However, in the past, the vertical deflection coil spacer was placed only on the projection of the separator to maintain the spacing. Therefore, the spacer is not stably positioned during assembly, and thus, many problems occur such that the spacer is displaced from the rain space, thereby maintaining accurate deflection magnetic field formation. It was hard to do.

The leakage magnetic field is known not only to adversely affect the operation of the electrical and electronic equipment near the screen, but also to deleteriously affect the human body.

Therefore, an apparatus for preventing the above leakage magnetic field has been developed and used.

The leakage magnetic field preventing device forms a magnetic field that cancels the leakage magnetic field by winding a coil around a core having a high permeability to flow a current.

The leak magnetic field preventing device can be mounted without shaking to obtain an even offset magnetic field.

Nevertheless, the conventional magnetic mounting means is not secured even after mounting, so that the leakage magnetic field prevention device itself may fall from side to side or behind, and thus a good offset magnetic field cannot be expected.

[Problems to Be Solved by the Invention]

The present invention has been made to solve the above problems, the object of the present invention is to maintain the vertical deflection coil spacer fixed and easy to easily detachable, and to prevent the movement by combining the leakage magnetic field prevention device with a strong fastening force It is to provide a separator for deflection yoke.

[Means to solve the problem]

In order to achieve the above object, the present invention, a fixing ring which can be fixed to the separator mounting a spacer for maintaining a predetermined gap between a pair of vertical deflection coil; It is formed on the flange portion characterized in that the magnetic field leakage preventing device fixed to hold the magnetic field leakage preventing device.

In addition, it characterized in that the vertical deflection coil spacer having a retaining hole formed in a shape corresponding to the fixing ring to be fixed to the fixing ring.

EXAMPLE

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

1 is an exploded perspective view of a deflection yoke according to the present invention, and FIG. 2 is a view for explaining the use of a spacer when mounting a vertical deflection coil, and FIG. 3 is a view for explaining the installation of a leakage magnetic field preventing device. Fig. 1 is a perspective view illustrating a deflection yoke assembly according to the present invention, and reference numeral 1 denotes a separator for deflection yoke.

A pair of horizontal deflection coils (not shown) attached to the inside of the separator 1 are separately installed, and a pair of vertical deflection coils 3 wound separately are mounted at predetermined intervals to prevent leakage magnetic fields. The deflection yoke is formed by mounting the device 5 on the flange 9.

The shape of the magnetic field of the vertical coil is an important point in order to optimally maintain the amount of change in the convergence yoke when assembling the deflection yoke.

Therefore, the pair of vertical deflection coils 3 should be installed in the separator 1 at a predetermined interval so as not to interfere with each other's magnetic field.

Therefore, a spacer 10 is required, and a fastening hole 11 is formed in the spacer 10, and the fastening ring 12 inserted into the hole 11 to fix the outer circumferential surface of the hole is fixed. Is formed in the separator 1.

The spacer 10 is flat and has a width such that a gap between the pair of vertical deflection coils 3 is formed.

The fixing ring 12 is formed in the inclined surface 14 to be symmetrical to each other in the entry portion 13, a pair of incision grooves 16 are formed in the rear end portion 15, the incision grooves 16 and A planar locking piece 7 is formed in a right angle direction.

Therefore, when the spacer 10 is inserted into the fixing ring 12, the inclined surface 14 of the ring 12 slides on the side wall of the fastening hole 11 of the spacer 10, After elastically deforming in a direction in which the width size is reduced and passing through the hole 11, the pair of locking pieces 17 are moved in a direction away from each other by the restoring force to be caught on the surface of the spacer 10.

In addition, the length of the neck portion 19 of the fixing ring 12 to match the thickness of the spacer 10, thereby to stabilize the mounting state of the spacer 10.

The width and thickness of the neck portion 19 of the fixing ring 12 allow the mounted spacer 12 to move slightly in the vertical, vertical, and horizontal directions so that the convergence can be adjusted even after the vertical deflection coil is installed.

The fixed holding device 20 formed on the flange 8 of the separator 1 is for holding the magnetic field leakage preventing device 5 fixed.

The fixed holding device 20 of the magnetic field leakage preventing device 5 has a stepped shape so that the hook portion 21 of the magnetic field leakage preventing device 5 is stepped to be symmetrical with each other so as to correspond to this. Form a box shape.

And the inclined surface 25 is formed on the upper side of each end (22, 24) of the fixed holding device 20 to facilitate the magnetic field leakage preventing device (5).

In addition, the inner end 22 facing the outer circumferential surface of the separator 1 forms a locking jaw 23 at the lower side thereof, and when the cumulative leakage preventing device 5 is mounted, the locking piece 26 of the hook portion 21 is formed. It is to be fixed and engaged with, and to form the same surface as the surface of the fixed holding device 20 and the surface of the hook portion 21 in the mounted state.

In addition, the outer end 24 facing the magnetic leakage preventing device 5 and acting as a guide when fastening is engaged with the insertion groove 27 of the hook portion 21 to be inserted therein, thereby preventing magnetic leakage after installation. This ensures a secure mounting condition for the separator (1) in (21).
