이 고안은 TV 및 모니터에 사용되는 음극선관에 관한 것으로서, 더욱 상세하게는 음극선관에 설치된 편향요크에서 발생하는 불요복사(Very Low Magnetic Field)를 감쇄시키기 위해 설치되는 불요복사 방지용 코일의 설치가 가능한 음극선관에 관한 것이다.The present invention relates to a cathode ray tube used in TVs and monitors, and more particularly, to install an unwanted radiation prevention coil installed to attenuate a very low magnetic field generated by a deflection yoke installed in the cathode ray tube. It relates to a cathode ray tube.

일반적으로, 음극선관에 설치되는 편향요크는 대개 한쌍의 수평편향코일과 수직편향코일로 구성되어 전자총에서 방사되는 빔을 수평 및 수직방향으로 편향시키는 자계를 형성하게 된다.In general, the deflection yoke installed in the cathode ray tube is generally composed of a pair of horizontal deflection coils and vertical deflection coils to form a magnetic field for deflecting the beam emitted from the electron gun in the horizontal and vertical directions.

그리고 이와 같은 음극선관 TV 또는 모니터등에 설치되는 것으로, 상기 편향요크의 누설자계에 의한 인체에 유해한 불요복사(VLMF)가 TV 또는 모니터의 외부로 방출됨에 따라 TV 시청자나 모니터앞에서 오래동안 근무하는 컴퓨터 사용자에게 좋지못한 영향을 미쳤던 것이다.And it is installed in such a cathode ray tube TV or monitor, computer users who work long hours in front of the TV viewer or monitor as VLMF harmful to the human body due to the leakage magnetic field of the deflection yoke is emitted to the outside of the TV or monitor. It had a bad effect on.

따라서, 상기와 같이 TV 또는 모니터에서 방출되는 불요복사를 규격치 이하로 낮추어 생산하도록 제품을 규격화 하기에 이르렀다.Therefore, it has come to standardize the product to produce by reducing the unnecessary radiation emitted from the TV or monitor as below the standard value.

종래에는 상술한 바와 같은 불요복사의 방출을 방지하기 위하여 제1도에 나타낸 바와같이, 음극선관(1)의 전편패널(2)에 편향요크(3)의 수평편향코일과 연결된 불요복사 방지용 코일(4)을 설치하여 편향요크(3)로부터 발생된 불요복사의 자계를 불요복사 방지용 코일(4)에서 발생되는 자계로 감쇄 시키도록 한 것이었다.Conventionally, as shown in FIG. 1, in order to prevent the emission of unnecessary radiation as described above, an unnecessary radiation preventing coil connected to the front deflection panel 2 of the cathode ray tube 1 and the horizontal deflection coil of the deflection yoke 3 ( 4) was installed to attenuate the undesired magnetic field generated from the deflection yoke (3) to the magnetic field generated by the undesired radiation preventing coil (4).

그러나, 상기와 같은 불요복사 방지용 코일(4)을 음극선관(1)의 전면패널(2)에 설치함에 있어 별도의 지지대(5)를 사용하였던 것으로, 이는 지지대(5)를 프라스틱 사출물로 성형하여 별도로 준비하여야 하고, 양면 테이프등의 접착수단으로 음극선관(1)의 전면패널(2) 상, 하측에 부착시켜야 하므로 조립공정상의 번거로움과 원가를 상승시키는 요인이 되었고, 또한 양면 테이프에 의한 접착력에 의존함에 따른 지지대의 유동 또는 음극선관으로 부터의 분리로 인해 그 목적을 다할 수 없는 문제점들이 발생하였던 것이다.However, in installing the unnecessary radiation preventing coil 4 on the front panel 2 of the cathode ray tube 1, a separate support 5 was used, which was formed by molding the support 5 into a plastic injection molding. It must be prepared separately and attached to the upper and lower sides of the cathode ray tube 1 by means of adhesive such as double-sided tape, which is a factor to increase the inconvenience and cost in the assembly process, and also the adhesive force by double-sided tape. Due to the dependence on the flow of the support or separation from the cathode ray tube problems that can not serve its purpose.

이 고안은 상기의 문제점을 감안하여 안출한 것으로, 이 고안의 목적은 음극선관에 설치한 펀향요크로부터 발생되는 불요복사를 감쇄시키기 위한 불요복사 방지용 코일을 음극선관의 전면패널에 직접 형성한 고정홈으로 설치되게 하여 별도의 부품을 제거함에 따른 조립공정의 단순화와 원가절감을 달성할 수 있어 생산성 향상에 기여하는 불요복사 방지용 코일의 설치가 가능한 음극선관을 제공하는데 있다.This invention has been devised in view of the above problems, and an object of this invention is to provide a fixing groove formed directly on the front panel of the cathode ray tube with an unnecessary radiation prevention coil to attenuate the unwanted radiation generated from the funnel yoke installed in the cathode ray tube. It is to provide a cathode ray tube that can be installed to prevent the unnecessary radiation to reduce the cost of the assembly process by eliminating the separate parts to achieve the installation to contribute to the productivity improvement.

상기의 목적을 달성하기 위한 이 고안은, TV 또는 모니터등의 음극선관에 설치된 편향요크로부터 발생되는 불요복사를 감쇄시키는 불요복사 방지용 코일을 설치함에 있어서, 상기 음극선관의 전면패널 상, 하부에 불요복사 방지용 코일을 고정할 수 있는 고정홈이 형성된 불요복사 방지용 코일의 설치가 가능한 음극선관에 그 특징이 있다.This invention for achieving the above object is unnecessary on the front panel and the lower part of the cathode ray tube in the installation of an unnecessary radiation prevention coil to attenuate the unnecessary radiation generated from the deflection yoke installed in the cathode ray tube such as a TV or a monitor. A cathode ray tube capable of installing an unnecessary radiation prevention coil having a fixing groove for fixing a radiation protection coil has its characteristics.

이하, 이 고안에 따른 실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, embodiments according to the present invention will be described in detail by the accompanying drawings.

제2도 및 제3도의 (a),(b)는 이 고안에 다른 불용복사 방지용 코일의 설치가 가능한 음극선관을 나타낸것으로, 전면패널(11)과 훤넬(12)로 이루어진 음극선관(10)의 네크부에 편향요크(13)가 장착되고, 상기 편향요크(13)에 전자총(14)이 설치된다.(A) and (b) of FIG. 2 and FIG. 3 show a cathode ray tube capable of installing another radiation preventing coil in this design, the cathode ray tube 10 consisting of the front panel 11 and the channel 12. The deflection yoke 13 is mounted on the neck portion of the neck, and the electron gun 14 is installed on the deflection yoke 13.

그리고, 상기 음극선관(10)의 전면폐널(11) 상,하부에 고청홈(11a)을 형성하고, 이 고정홈(11a)에 편향요크(13)의 수평편향코일과 연결된 불요복사 방지용 코일(15)이 설치된다.In addition, the high radiation groove (11a) is formed in the upper and lower front panel 11 of the cathode ray tube (10), and the unnecessary radiation prevention coil connected to the horizontal deflection coil of the deflection yoke (13) in the fixing groove (11a) 15) is installed.

이와같은 이 고안은 TV 또는 모니터에 설치되는 것으로, 전자총(14)에서 방사되는 전자빔을 편향요크(13)의 수직 및 수평편향코일이 편향시켜 음극선관(10)의 전면패널(11) 내측면에 도포한 형광층에 충돌되도록 함으로써 화상이 나타나게 되고, 제2도에서와 같이 상기의 펀향요크(13)에서 형성된 누설자계(a)에 의해 불요복사(b)가 음극선관(10)의 전방으로 방출된다.This design is installed in a TV or monitor, and the vertical and horizontal deflection coils of the deflection yoke 13 deflect the electron beam emitted from the electron gun 14 to the inner side of the front panel 11 of the cathode ray tube 10. The image appears by impinging on the applied fluorescent layer, and as shown in FIG. 2, unnecessary radiation (b) is emitted to the front of the cathode ray tube 10 by the leakage magnetic field a formed in the funnel yoke 13 above. do.

이때 전면패널(11)의 고정홈(11a)에 설치된 불요복사 방지용 코일(15)에 의해 형성된 역자계(c)로서 불요복사(b)가 감쇄되어 인체에 유해한 불요복사(b)가 음극선관(10)의 외부로 방출되지 않게 되는 것이다.At this time, the unnecessary radiation (b) as the reverse magnetic field (c) formed by the unnecessary radiation prevention coil 15 installed in the fixing groove (11a) of the front panel 11 is attenuated radiation (b) is harmful to the human body is a cathode ray tube ( 10) will not be released to the outside.

또한, 이 고안은 상기와 같은 불요복사를 감쇄시키기 위한 불요복사 방지용 코일(15)이 제3도의 (b)에서와같이 음극선관(10)의 전면패널(11)상,하부에 형성된 고정홈(11a)에 직접 설치됨으로써, 음극선관(10)의 스크린 유효면에 가깝게 되어 불요복사를 감쇄시키는 효과가 증대될 수 있는 것이고, 외관 조립시의 조립성도 좋아지게 되는 것이다.In addition, the present invention is a fixing groove formed on the lower portion of the front panel 11 of the cathode ray tube 10 as shown in (b) of FIG. By being installed directly at 11a), the effect of reducing the unnecessary radiation by being closer to the screen effective surface of the cathode ray tube 10 can be increased, and the assembling property at the time of appearance assembly is also improved.

이상에서와 같이 이 고안에 의하면 불요복사를 감쇄시키는 불요복사 방지용 코일이 음극선관의 전면패널에 형성한 고정홈에 직접 설치됨으로써 불요복사의 감쇄효과가 증대되고, 별도의 부품이 제거되어 조립능률이 향상되며, 원가를 절감할 수 있어 생산성 향상에 기여할 수 있는 효과가 있는 것이다.As described above, according to this design, since the unnecessary radiation preventing coil for reducing unnecessary radiation is directly installed in the fixing groove formed on the front panel of the cathode ray tube, the attenuation effect of unnecessary radiation is increased, and the separate parts are removed to increase the assembly efficiency. It can be improved and cost can be reduced, which can contribute to productivity improvement.
