ツト装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a convergence correction magnet device that is attached to the neck of an in-line color cathode ray tube in which R, G, and B electron guns are arranged on the same line.

ず調整作業の際、非常に不便であつた。 As shown in FIG. 1, a conventional magnetic device has a plurality of tongues 2 and a collar 3 that are clamped to the neck of a cathode ray tube by means of clamps (not shown).
2 on a synthetic resin holding body 1 having a cylindrical part.
The pole magnets 4, 4, the 4-pole magnets 5, 5, and the 6-pole magnets 6, 6 are separated by spacers 7, 7, and a screw groove 8 is formed at the end of the holding body 1.
A lock body 9 was screwed onto the lock body to hold the clamping pressure. However, in such a conventional convergence correction magnet device, the magnet may not be able to rotate depending on the degree of tightening by the locking body 9, and if the tightening is too weak, the position of the magnet in the rotation direction may not be determined. This was extremely inconvenient during adjustment work.
このため、着磁数の異なる複数ケのリング状マ

昭51−56920号公報で提案せられている。 For this reason, there is a device in which a plurality of ring-shaped magnets with different numbers of magnetizations are attached between the claws and the flanges of a cylindrical holder via an insulating ring, and a spring piece is integrally provided on at least one of the insulating rings. This was proposed in Utility Model Application Publication No. 51-56920.
しかしながら、この公知例では絶縁リングにバ
ネ片が厚さ方向に突出しているだけであるから、
リング状マグネツトに与える弾性力が弱く、従つ
てリング状マグネツトに十分なトルクを与える保
持状態が得られないという欠点を有する。 However, in this known example, since the insulating ring only has a spring piece protruding in the thickness direction,
The disadvantage is that the elastic force applied to the ring-shaped magnet is weak, and therefore a holding state that provides sufficient torque to the ring-shaped magnet cannot be obtained.

That is, in the present invention, as shown in FIG. 2, a ring-shaped wave spacer 10 made entirely of elastic synthetic resin is used as a spacer for separating magnets having different magnetization numbers, and a pair of ring-shaped wave-shaped spacers 10 are used as shown in FIG. The wave-shaped spacer is characterized in that it has a symmetrical wave-shaped arrangement with respect to the ring-shaped magnets 5, 5 between them.
Further, a guide groove 15 is formed on the cylindrical portion 12 of the holder 11 , and a guide protrusion 16 that fits into the guide groove 15 is formed on the wave-shaped spacer 10.
16 in the wall thickness direction and the wave-shaped spacer 10 is installed along the groove 15 as shown in FIG. 3, each magnet 4, 4, 5, 5, 6, 6
The spacers 10, 10 do not move in the direction of rotation, and there is no possibility that the spacers 10 will rotate undesirably during adjustment rotation of the various magnets. Suitable materials for the corrugated spacer 10 include polycarbonate and polyacetal resin (trade name: "Dyuracon").

ま保持されるという効果がある。 Incidentally, a metallic corrugated spacer has been used as a spacer to separate the magnets in a centering magnet device for a black-and-white television receiver, but in this centering magnet device, a corrugated spacer with a relatively small diameter is used. However, in the convergence correction magnet device targeted by this invention, the magnets have a large diameter and are arranged in pairs, so it is necessary to use a corrugated spacer to separate these magnets. The elasticity must be large. Therefore, if a metal spacer is used in a convergence correction magnet device, the spacer must be made considerably thicker and stronger, but this method makes it difficult to punch, press, etc. Moreover, there is a risk that burrs may occur, and it is generally inappropriate to use a metallic wave-shaped spacer in the magnet device to which the present invention is directed. On the other hand, since the wave-shaped spacer of the present invention is made of elastic synthetic resin, it can be molded to have a large wall thickness and diameter.
It is possible to separate the pole magnets 5, 5 and the hexapole magnets 6, 6 with sufficient elasticity. Further, since the waveform positions of the pair of waveform spacers 10, 10 are made symmetrical with respect to the magnets 5, 5 between them as shown in FIG. 4, the biasing state against the ring-shaped magnet is stabilized. Therefore, according to the present invention, the adjustment rotation of each magnet is accompanied by an appropriate torque, and since the torque is constant, adjustment is easy to perform, and the magnet position after adjustment is maintained as it is.
