である。 The above magnetic piece is placed on the front flange of the coil separator that separates the horizontal coil and the vertical coil, but its purpose is to allow two vertical coils to be solenoid-wound around each curved fan-shaped ferrite core. Therefore, when the end faces of each core are combined into a truncated cone shape and combined with a saddle-shaped horizontal coil via a coil separator, magnetic flux is prevented from leaking from the joint of the core end faces, and deflection pincushion distortion of the screen is prevented. This is to ensure that it is corrected correctly.

図に示すような偏向ヨーク装置を構成できる。Technical Background of the Invention For this reason, it is desirable that the magnetic piece be securely attached around the front flange portion of the coil separator. Therefore, conventionally, notches 3, 3 were provided in the legs 2, 2 of the magnetic piece 1 shown in FIG. It is set up. Furthermore, as shown in the enlarged cross-sectional view of FIG. The positioning is done in the axial direction. Thus, this magnetic piece 1 is placed on the coil separator 4.
If you attach the necessary parts and attach it, the third

2からそのネツク部が突き出るようになる。 Figure 3 shows two-part coil separators 4, 4 fitted together, horizontal coils 8, 8 on the inside and vertical coil 1 wound around ferrite cores 9, 9 on the outside.
FIG. 2 is a perspective view of a conventional deflection yoke device in which the coils 0 and 0 are attached, and the winding wires of both coils extend from the terminal plate portion 11 at the rear. The magnetic pieces 1, 1 are arranged on the side of the core parts 9, 9 where the vertical coils 10, 10 are not wound, and pick up magnetic flux leaking from the core parts 9, 9. A cathode ray tube (not shown) is inserted from the front enlarged part of this device and is inserted into the rear cylindrical part 1.
The neck part will protrude from 2.
背景技術の問題点
しかして、磁性片1は一般に冷間圧延けい素鋼
帯を用い、その平板よりプレス加工にて最終形状
としているが、これによる材質の機械的な延び率
のばらつき及びプレス加工時のばらつきによつて
切込み3の位置が一定しないという問題があつ
た。Problems with the Background Art However, the magnetic piece 1 is generally made of a cold-rolled silicon steel strip, and its final shape is formed by press working from a flat plate, but this causes variations in the mechanical elongation of the material and press working. There was a problem that the position of the cut 3 was not constant due to variations in time.
このため、磁性片1がコイルセパレータ4と相
接合する部分における切込み3の位置は、その段
部からの寸法Aをコイルセパレタ4の弾性突起6
内側の係合爪7の位置より大きめにしなければな

ランジ部5と磁性片1とが接する周方向の平面部
13にすき間Bを生ずる虞れがある。このため、
磁性片1がブラウン管の軸方向にぐらつき画面糸
巻き歪の補正が正しく行なわれない嫌いがあつ
た。 Therefore, the position of the cut 3 in the part where the magnetic piece 1 joins the coil separator 4 is determined by the dimension A from the stepped part to the elastic protrusion 6 of the coil separator 4.
It has to be larger than the position of the inner engaging claw 7, and therefore, there is a risk of creating a gap B in the circumferential plane part 13 where the front flange part 5 of the coil separator 4 and the magnetic piece 1 are in contact. . For this reason,
The magnetic piece 1 wobbles in the axial direction of the cathode ray tube, making it impossible to correct screen pincushion distortion correctly.
そこで、第1図に示すような磁性片1の両脚部
2,2の中間部に、コイルセパレータ4の前方フ
ランジ部5の平面部13に当接する固定爪14を

状が複雑となる上糸巻き歪の補正には関与しない
部分であるから磁性片1の安定に対しては賢明な
手段とは言い難い。 Therefore, a fixing claw 14 is provided in the middle of the legs 2, 2 of the magnetic piece 1 as shown in FIG. Protruding claws 15, 15 similar to the elastic protrusion 6 may be provided, and the fixing claw 14 may be fitted between the protruding claws 15, 15, and this portion may ultimately be fixed with adhesive. However, since this fixing claw 14 does not take part in correcting needle winding distortion, which has a complicated shape, it cannot be said to be a wise means for stabilizing the magnetic piece 1.
このように従来、コイルセパレータ4の前方フ
ランジ部5に固定する磁性片1がブラウン管の軸
方向に動かないようにフランジ部5の平面部13

た。 In this way, conventionally, the flat part 13 of the flange part 5 is fixed to the front flange part 5 of the coil separator 4 so that the magnetic piece 1 fixed to the front flange part 5 does not move in the axial direction of the cathode ray tube.
In order to attach the magnetic piece 1 and the leg part of the magnetic piece 1 in close contact with each other, it is difficult to accurately attach the magnetic piece 1 due to the difference in processing dimensions.

and the cylindrical portion 25 are integrally molded. At the upper stage of the conical portion 23 are pieces 26, 26 for positioning a vertical coil, which will be described later. A joining claw 27 is formed on the end face of the front flange portion 22 to join with the other coil separator. Furthermore, locking claws 29 are integrally molded at predetermined positions on both ends of the flat portion 28 of the front flange portion 22 and protrude in the axial direction of the cathode ray tube.

との差を吸収できるものとなつている。 As shown in FIG. 6, this locking pawl 29 has a head 30 in a substantially umbrella shape, and the diameter of the support portion 31 connected to the flange portion flat surface 28 that supports the head 30 is determined by the diameter of the head 30.
In addition to making the diameter slightly smaller than the maximum diameter of
The height C of the support portion 31 is set to be approximately the same as the thickness T of the magnetic piece. In addition, the locking pawl 29 has a slit 32 in the center of the flange portion 2 in FIG.
It is formed up to a portion excluding the plate thickness of the flat portion 28 of No. 2. The height dimension of this slit 32 is the head 3
It is sufficient that the diameter is made to be approximately the same as the diameter of the support portion 31 when the 0 is pushed from both sides, and for example, it may be formed so as to pass through the locking pawl 29. In other words, the minimum necessary interval between the slits 32 is such that the difference between the diameter of the support portion 31 and the maximum diameter of the head 30 can be accommodated.

It has an inwardly curved pressed shape with 34 mm. The intermediate portion 35 is formed to curve outward in a direction different from the curve direction of both end portions.
This has the advantage that the curvature of the legs 34, 34 of the magnetic piece 33 can be adjusted both outwardly and inwardly. In other words, the magnetic piece 33 is made larger or smaller than the curvature of the circumference of the coil separator 21, and when both are attached, the magnetic piece 33 due to the difference in curvature
The urging force allows the locking pawl 29 to more firmly attach the magnetic piece 33. That is, the leg portion 34 has a step portion 36 that contacts the front flange portion 22 of the coil separator 21.
One or more through-holes 37 are provided in the plane part of. This through hole 37 corresponds to the locking pawl 29 formed in the coil separator 21, and its diameter is the same as that of the locking pawl 29.
The diameter of the support portion is approximately the same as that of the support portion. Note that the code N indicates the core 38' of the vertical coil 38,
38'.
