Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は、テレビジョン受像機等の陰極線管に設ける偏向ヨークに関するも のである。 The present invention relates to a deflection yoke provided in a cathode ray tube of a television receiver or the like.

【0002】[0002]

【従来の技術】[Prior art]

従来例の偏向ヨークは、偏向磁界を発生するために陰極線管に取付けるもので 磁芯にコイルを巻回したものであった。すなわち、図5に示すように、コーン形 の巻線枠21の大径部(図示せず)および小径部の端部に複数本の銅線案内溝2 1aを形成し、巻線枠21の内周部に各銅線案内溝1aと対応して巻線枠21の 軸方向に延びるスロット21cを形成し、巻線枠21に、一対のくら形コイル5 を複数の電線束に分けて各銅線案内溝21aおよび各スロット21c内に沿って 巻付けていた。 The deflection yoke of the conventional example is attached to a cathode ray tube in order to generate a deflection magnetic field, and has a coil wound around a magnetic core. That is, as shown in FIG. 5, a plurality of copper wire guide grooves 21a are formed at the ends of the large-diameter portion (not shown) and the small-diameter portion of the cone-shaped winding frame 21 to form the winding frame 21. A slot 21c extending in the axial direction of the winding frame 21 is formed in the inner peripheral portion so as to correspond to each copper wire guide groove 1a, and in the winding frame 21, a pair of saddle-shaped coils 5 are divided into a plurality of electric wire bundles. It was wound along the copper wire guide groove 21a and each slot 21c.

【0003】 巻線枠21は、生産上の理由で各銅線案内溝21aの切込長さを中央部で最も 短く中央部から離れるにしたがって長くなるように設定していた。これは、巻線 枠21にくら形コイル5を巻回するに当たって巻回始めから順次巻回終りまでの 間に、くら形コイル5の締付力によって巻線枠21が変形して巻線枠21をブラ ウン管(図示せず)に取付けるのが困難になることを防止するためである。For manufacturing reasons, the winding frame 21 is set such that the cut length of each copper wire guide groove 21a is the shortest in the central portion and becomes longer as the distance from the central portion increases. This is because when winding the saddle coil 5 around the winding frame 21, the winding frame 21 is deformed by the tightening force of the saddle coil 5 between the start of winding and the end of the winding. This is to prevent it from becoming difficult to attach 21 to the braun pipe (not shown).

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来例の偏向ヨークでは、各スロット21cの長さは、各銅線案内溝21aの 切込長さとの関係で中央部cで最も長く、中央部cから離れるにしたがって短く なっていた。このため、巻線枠21内に発生する磁界はブラウン管の管軸方向の 銅線長さ、すなわちくら形コイル5のスロット21c内に沿った部分の長さによ って決定されるので、図9に示すようなブラウン管のCRTスクリーン面4の平 面度の関係で起こる青色の電子ビームの輝線2と赤色の電子ビームの輝線3との ミスコンバージェンス(色ずれ)が生じた。これは、図6(a)に示すように、 ブラウン管の電子銃から射出された赤色の電子ビームRおよび青色の電子ビーム Bは矢印aで示した磁界によって各々同じ力を受けるが、緑色の電子ビームGは 両者と異なった力を受けるからである。 In the deflection yoke of the conventional example, the length of each slot 21c is the longest in the central portion c in relation to the cut length of each copper wire guide groove 21a, and becomes shorter as the distance from the central portion c increases. For this reason, the magnetic field generated in the winding frame 21 is determined by the length of the copper wire in the tube axis direction of the cathode ray tube, that is, the length of the portion along the slot 21c of the square coil 5. As shown in FIG. 9, a misconvergence (color shift) between the emission line 2 of the blue electron beam and the emission line 3 of the red electron beam occurred due to the flatness of the CRT screen surface 4 of the cathode ray tube. This is because, as shown in FIG. 6A, the red electron beam R and the blue electron beam B emitted from the electron gun of the cathode ray tube receive the same force by the magnetic field indicated by the arrow a, but the green electron This is because the beam G receives different forces from the two.

【0005】 そこで、前述のミスコンバージェンスを修正するために、次のようなことが提 案された。すなわち、図9に示したCRTスクリーン面4のb部分を例にとって 説明すると、赤色の電子ビームの輝線3を上方へ偏向するための磁界をCRTス クリーン面4側へ寄せて形成することにより、図7に示すように赤色の電子ビー ムRを青色の電子ビームBよりも上方へ偏向しようとするものであった。Therefore, in order to correct the above-mentioned misconvergence, the following has been proposed. That is, to explain using the b portion of the CRT screen surface 4 shown in FIG. 9 as an example, by forming a magnetic field for deflecting the bright line 3 of the red electron beam upward toward the CRT screen surface 4 side, As shown in FIG. 7, the red electron beam R is intended to be deflected above the blue electron beam B.

【0006】 しかしながら、図8の矢印d,eに各々示すように、赤色の電子ビームRが青 色の電子ビームBよりも強く上方へ偏向されることになった。また、図6(b) に示すように中央部cに巻回したくら形コイル5の巻線数が多いと、巻線枠21 の後端付近で緑色の電子ビームGを矢印d方向へ偏向し過ぎることになった。こ のため、図10に示すように、赤色の電子ビームの輝線3よりも緑色の電子ビー ムの輝線6が外方にずれるといったミスコンバージェンスが生じた。However, as indicated by arrows d and e in FIG. 8, the red electron beam R is deflected upward more strongly than the blue electron beam B. Further, as shown in FIG. 6B, when the number of windings of the paddle-shaped coil 5 wound around the central portion c is large, the green electron beam G is deflected in the direction of arrow d near the rear end of the winding frame 21. It was too much. For this reason, as shown in FIG. 10, a misconvergence occurred in which the emission line 6 of the green electron beam is shifted outward from the emission line 3 of the red electron beam.

【0007】 この考案の目的は、ミスコンバージェンスを防止する偏向ヨークを提供するこ とである。An object of the present invention is to provide a deflection yoke that prevents misconvergence.

The deflection yoke according to claim 2 further has a copper wire guide groove formed at an end of the winding frame corresponding to each slot of the winding frame, and a bottom surface of the copper wire guide groove is lowered toward a central portion. Incline.

【作用】 請求項1記載の偏向ヨークは、巻線枠に形成した筒軸方向に延びる複数のスロ ットのうちの中央部のスロットを最も短く形成し、その他のスロットを中央部か ら離れるに従って順次短く形成しているため、赤色の電子ビームを上へ偏向する 磁界を巻線枠の後端内方に形成することなく、ブラウン管等の電子銃から射出さ れた赤色の電子ビームおよび青色の電子ビームと、緑色の電子ビームとが異なっ た力を受けて生じるミスコンバージェンスを修正することができる。In the deflection yoke according to the first aspect, the central slot of the plurality of slots formed in the winding frame and extending in the cylinder axis direction is formed to be the shortest, and the other slots are separated from the central portion. Therefore, the red electron beam and the blue electron beam emitted from an electron gun such as a cathode ray tube are formed without forming a magnetic field inside the rear end of the winding frame to deflect the red electron beam upward. It is possible to correct the misconvergence caused by the different forces applied to the green electron beam and the green electron beam.

【実施例】【Example】

この考案の第1の実施例の偏向ヨークは、図1ないし図3に示すように、筒軸 方向に延びる複数のスロット1cを形成した筒形の巻線枠1と、巻線枠1の各ス ロット1cに巻付けた一対のくら形コイル5とを備えている。複数のスロット1 cのうちの中央部cのスロット1cを最も短く形成し、その他のスロット1cを 中央部cから離れるに従って順次短く形成している。 The deflection yoke according to the first embodiment of the present invention is, as shown in FIGS. 1 to 3, a cylindrical winding frame 1 having a plurality of slots 1c extending in the cylinder axial direction, and each of the winding frames 1. It is provided with a pair of paddle-shaped coils 5 wound around the slot 1c. Of the plurality of slots 1 c, the slot 1 c at the central portion c is formed to be the shortest, and the other slots 1 c are sequentially formed to be shorter as the distance from the central portion c is increased.

【0012】 巻線枠1は、両端部にスロット1cに対応して複数の銅線案内溝1a,1bを 切込形成している。銅線案内溝1aは巻線枠1の端面からの切込長さが最も長く 、銅線案内溝1bは銅線案内溝1aから離れるに従って巻線枠1の端面からの切 込長さが順次短く形成されている。一対のくら形コイル5は、巻線枠1に、それ ぞれ複数の電線束に分けて銅線案内溝1a,1bおよびスロット1c内に沿って 巻付けられている。The winding frame 1 is formed with a plurality of copper wire guide grooves 1a and 1b at both ends corresponding to the slots 1c. The copper wire guide groove 1a has the longest cut length from the end face of the winding frame 1, and the copper wire guide groove 1b has the cut length from the end face of the winding frame 1 sequentially away from the copper wire guide groove 1a. It is formed short. The pair of saddle-shaped coils 5 are wound around the winding frame 1 along the copper wire guide grooves 1a and 1b and the slot 1c in a plurality of electric wire bundles.

【0013】 このように構成した偏向ヨークによると、従来例のように赤色の電子ビームR を上方へ偏向するための磁界を巻線枠1のCRTスクリーン4側に寄せて形成す ることなく、ブラウン管の電子銃から射出された赤色の電子ビームRおよび青色 の電子ビームBと、緑色の電子ビームGとが異なった力を受けることにより生じ るミスコンバージェンスを修正することができる。したがって、巻線枠1の後端 付近で緑色の電子ビームGを偏向し過ぎることなく、赤色の電子ビームの輝線3 よりも緑色の電子ビームの輝線6が外方にずれるといったミスコンバージェンス を防止することができる。According to the deflection yoke configured as described above, it is possible to form a magnetic field for deflecting the red electron beam R 1 upward without forming it near the CRT screen 4 side of the winding frame 1 unlike the conventional example. It is possible to correct misconvergence caused by different forces of the red electron beam R and the blue electron beam B emitted from the CRT electron gun and the green electron beam G. Therefore, the green electron beam G is not excessively deflected in the vicinity of the rear end of the winding frame 1, and the misconvergence in which the green electron beam emission line 6 is shifted outward from the red electron beam emission line 3 is prevented. be able to.

【0014】 つぎに、この考案の第2の実施例の偏向ヨークは、図4に示すように巻線枠1 1の両端の少なくとも一方の銅線案内溝11a,11bの底面11cを、中央部 cに向かって下り傾斜させているので、くら形コイル5が巻線枠1の中央部cに 向かって下り傾斜して重なり合うことになり、安定した巻線ができる。 なお、この他の構成および効果については第1の実施例と同様である。Next, in the deflection yoke of the second embodiment of the present invention, as shown in FIG. 4, the bottom surface 11c of at least one of the copper wire guide grooves 11a and 11b at both ends of the winding frame 11 is provided at the central portion. Since the slanted coil 5 is inclined downward toward c, the saddle-shaped coil 5 is inclined downward toward the central portion c of the winding frame 1 and overlaps with each other, so that stable winding can be performed. The other configurations and effects are similar to those of the first embodiment.
