상기 콘버젼스를 보정하기 위한 콘버젼스 요크코일(3)은 투자율이 높은 철심(4)에 권선되어 있어, 상기 콘버젼스 요크코일(3)에서 보정자계(A)가 발생할 경우 전자총에서 방사되는 청색빔(B) 및 적색빔(R)이 편향되어 콘버젼스를 보정하게 된다.The convergence yoke coil 3 for correcting the convergence is wound around an iron core 4 having a high permeability, and is radiated by an electron gun when a correction magnetic field A occurs in the convergence yoke coil 3. The blue beam B and the red beam R are deflected to correct the convergence.

종래 콘버젼스 요크코일이 체결되는 편향요크홀더는 도 4와 도 5에 도시된 바와 같이, 콘버젼스 요크코일(3)이 권선된 철심(4)이 장착되는 편향요크홀더의 넥크부는 철심(4)의 전면 끝부분이 체결되는 체결돌기(7)와, 상기 체결돌기(7)에 체결된 철심(4)의 후면 끝부분이 고정하기 위한 고정돌기(8)로 구성된 것이다.The deflection yoke holder to which the conventional convergence yoke coil is fastened, as shown in FIGS. 4 and 5, the neck portion of the deflection yoke holder on which the iron core 4 wound around the convergence yoke coil 3 is mounted is provided with an iron core ( 4) the front end of the fastening projection 7 is fastened to, and the rear end of the iron core (4) fastened to the fastening projection (7) is composed of a fixing projection (8) for fixing.

이와 같이 구성된 종래 콘버젼스 요크 코일이 체결되는 편향요크홀더는 도 4와 도 5에 도시된 바와 같이, 도 1내지 도 3을 참고로하여 설명하면 다음과 같다.The deflection yoke holder to which the conventional convergence yoke coil is fastened as described above is described with reference to FIGS. 1 to 3 as follows.

전자총에서 방사되는 전자빔을 상하로 편향시키는 수직코일(1)과 좌우로 편향시키는 수평코일(2)이 권선된 편향요크의 넥크부에 상기 콘버젼스를 보정하기 위한 콘버젼스 요크코일(3)이 철심(4)에 권선되어 장착되게 된다.Convergence yoke coil (3) for correcting the convergence in the neck portion of the deflection yoke in which the vertical coil (1) for deflecting the electron beam emitted from the electron gun up and down and the horizontal coil (2) for deflecting from side to side The iron core 4 is wound and mounted.

이때, 편향요크 홀더의 넥크부에는 콘버젼스 요크코일(3)이 권선된 철심(4)이 체결고정되도록 상기 철심(4)의 전면 끝부분이 체결되도록 체결돌기(7)가 돌출되어 있고, 철심(4)의 후면 끝부분이 고정되도록 고정돌기(8)가 돌출되어 있어 상기 콘버젼스 요크코일(3)을 편향요크 홀더의 넥크부에 장착시 체결돌기(7)와 고정돌기(8)사이에 장착한후 상기 철심(4)이 돌기부(7,8)에서 이탈되는 것을 방지하기 위해 체결부위에 접착제를 도포하게 되므로서, 편향요크 홀더의 넥크부에 철심(4)이 장착완료된다.At this time, the fastening protrusion 7 protrudes from the neck portion of the deflection yoke holder so that the front end of the iron core 4 is fastened so that the iron core 4 wound around the converged yoke coil 3 is fastened and fixed. The fixing protrusion 8 protrudes so that the rear end of the iron core 4 is fixed so that the fastening protrusion 7 and the fixing protrusion 8 when the converged yoke coil 3 is mounted on the neck of the deflection yoke holder. Since the iron core 4 is applied to the fastening portion to prevent the iron core 4 from being separated from the protrusions 7 and 8 after being mounted therebetween, the iron core 4 is completed in the neck portion of the deflection yoke holder.

즉, 철심(4)이 편향요크 홀더의 넥크부에 장착되었을 브라운관판넬과 전자총사이에 고정장착되도록 상기 편향요크 홀더의 넥크부에 체결밴드(5)를 체결하고 볼트(6)를 이용하여 편향요크 홀더의 넥크부를 정확하게 체결고정시킨다.That is, the fastening band 5 is fastened to the neck portion of the deflection yoke holder so that the iron core 4 is fixedly mounted between the CRT and the electron gun which will be mounted on the neck portion of the deflection yoke holder. Fasten the neck of the holder correctly.

이와 같이, 콘버젼스 요크코일(3)이 권선된 철심(4)이 편향요크 홀더의 넥크부에 장착완료되어 동작시 투자율이 높은 철심(4)에 권선된 콘버젼스 요크코일(3)에서는 보정자계(A)가 발생하게 되어, 상기 전자총에서 방사되는 청색빔(B) 및 적색빔(R)이 보정자계(A)에 의해 편향되므로서 콘버젼스를 보정하게 된다.As described above, in the converged yoke coil 3 wound around the iron core 4 having the high permeability during operation, the iron core 4 wound around the converged yoke coil 3 is completed. The correction magnetic field A is generated, and the blue beam B and the red beam R emitted from the electron gun are deflected by the correction magnetic field A to correct the convergence.

그러나 종래 편향요크의 콘버젼스 요크코일(3)은 철심(4)에 권선되어 편향요크홀더의 넥크부에 장착되므로서 상기 편향요크를 체결하기 위한 체결밴드(5)와 콘버젼스 요크코일(3)사이에서 전위차가 발생하게 되고, 상기 발생한 전위차에 의해 콘버젼스 요크코일(3)이 권선된 철심(4)과 체결밴드(5)사이에서 스파크(SPARK)가 발생하게 된다.However, the convergence yoke coil 3 of the conventional deflection yoke is wound on the iron core 4 and mounted to the neck portion of the deflection yoke holder, so that the fastening band 5 and the convergence yoke coil for fastening the deflection yoke ( A potential difference is generated between 3) and a spark (SPARK) is generated between the iron core 4 on which the converged yoke coil 3 is wound and the fastening band 5 by the generated potential difference.

즉, 콘버젼스 요크코일(3)이 권선되는 철심(4)의 끝부분이 노출되므로서 체결밴드(5)와의 공간거리 및 옆면거리가 짧아 상기 콘버젼스 요크코일(3)에 전류가 인가되면 체결밴드(5)와의 전위차가 발생하게 되므로서 상기 발생한 전위차에 의해 스파크가 발생하여 화재가 발생할 우려가 있으며, 체결밴드(5)의 체결작업이 어렵게 되고, 상기 철심(4)을 편향요크홀더에 형성된 돌기부사이에 체결고정시 상기 철심(4)이 돌기부에서 이탈되는 것을 방지하기 위해 접착제를 추가로 도포하므로서 접착작업에 의해 생산성 이 저하되고, 제품의 외관 및 품질불량이 발생하게 되는 문제점이 있었다.That is, since the end of the iron core 4 on which the converged yoke coil 3 is wound is exposed, the clearance distance and the side distance with the fastening band 5 are short, so that a current is applied to the converged yoke coil 3. When the potential difference with the fastening band 5 is generated, a spark may be generated due to the generated potential difference, and a fire may occur, and the fastening operation of the fastening band 5 becomes difficult, and the deflection yoke holder is deflected. When the fastening is fixed between the protrusions formed in the iron core (4) by applying an additional adhesive to prevent the separation from the protrusions, productivity was reduced by the bonding operation, there was a problem that the appearance and poor quality of the product occurs .

본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 편향요크홀더의 넥크부에 포켓형상의 홈을 형성시켜 콘버젼스 요크코일이 권선된 철심을 넥크부에 체결장착시 철심의 전면 끝부분이 포켓형상의 홈에 체결시키므로서 상기 철심과 체결밴드사이의 공간거리 및 옆면거리가 확보되어 스파크발생을 방지할수 있도록 한 것으로, 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.The present invention forms a pocket-shaped groove in the neck portion of the deflection yoke holder in order to solve such a conventional problem, and the front end of the iron core is pocket-shaped when fastening and mounting the iron core wound with the converged yoke coil to the neck portion. The distance and the side distance between the iron core and the fastening band is secured by fastening to the groove of the spark to prevent the occurrence of spark. The configuration and effect of the present invention will be described with reference to the accompanying drawings.
