본 고안은 TV나 컴퓨터등의 모니터로 사용되고 있는 음극선관에 관한 것이다.The present invention relates to a cathode ray tube used as a monitor such as a TV or a computer.
음극선관을 동작하는 경우 -로 대전된 전자빔이 음극선관 패널의 화면부 내면에 충돌하여 음극선관 패널의 화면부 외면(즉, 화면)은 +로 대전되게 된다. 이때, 음극선관의 사용자가 화면에 접촉하는 경우에는 전기 쇼크를 받아서 불쾌하게 될 뿐만아니라 심한 경우에는 건강상에 손상을 초래하게 된다.In the case of operating the cathode ray tube, the electron beam charged with − collides with the inner surface of the screen portion of the cathode ray tube panel, so that the outer surface of the cathode ray tube panel (ie, the screen) is charged with +. At this time, when the user of the cathode ray tube comes into contact with the screen, not only is it unpleasant to receive an electric shock, but in severe cases may cause health damage.
종래에는 전술한 문제점을 해결하기 위해서 음극선관 패널 화면부 외면의 도전물질이 포함된 코팅막과 접지된 방폭보강밴드 사이에 도전성 테이프를 부착하여 화면부 외면의 정전기를 제거해 왔다.Conventionally, in order to solve the above problems, a conductive tape is attached between the coating film containing the conductive material on the outer surface of the cathode ray tube panel screen and the ground explosion-proof reinforcement band to remove static electricity from the outer surface of the screen.
그러나, 전술한 종래 기술에 따르면 도전성 테이프가 떨어지거나 긁혀서 손상되는 경우가 많으며 또한 접착제가 포함되어 있어서 화면부 외면의 정전기를 신속하며 확실하게 제거할 수 없는 문제점이 있었다.However, according to the above-described prior art, the conductive tape is often damaged by falling or scratching, and also includes an adhesive, and thus there is a problem in that static electricity on the outer surface of the screen portion cannot be removed quickly and reliably.
본 고안은 전술한 문제점을 해결하기 이해서 안출된 것으로서 본 고안의 목적은 음극선관의 화면부 외면에 발생되는 정전기를 신속하며 또한 확실하게 제거할 수 있는 음극선관을 제공하기 위한 것이다.The present invention has been made to solve the above-described problems, the object of the present invention is to provide a cathode ray tube that can quickly and reliably remove the static electricity generated on the outer surface of the cathode ray tube.
전술한 목적을 달성하기 위해서, 본 고안은 패널의 화면부 외면에는 도전성 물질이 포함된 코팅막이 도포되어 있으며 또한 패널과 펀늘의 봉착부에는 접지된 방폭보강밴드가 장착되어 있는 음극선관에 있어서, 상기 코팅막과 방폭보강밴드 사이에 단부에 약간의 중첩이 이루어지게 하면서 도전성 물질로 코팅된 도전물질 도포부를 형성한 것을 특징으로 하는 음극선관을 제공해준다.In order to achieve the above object, the present invention is a cathode ray tube in which a coating film containing a conductive material is applied to the outer surface of the screen portion of the panel, and the explosion-proof reinforcement band is grounded at the sealing portion of the panel and the funnel. It provides a cathode ray tube, characterized in that a conductive material coated portion coated with a conductive material is formed while making a slight overlap at the end between the coating film and the explosion-proof reinforcing band.
이하에서는 첨부도면을 참조하여 본 고안의 양호한 일실시예를 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.
제1도는 본 고안의 양호한 일실시예에 따른 음극선관을 도시하는 일부절개 사시도이다.1 is a partially cutaway perspective view showing a cathode ray tube according to a preferred embodiment of the present invention.
참조번호 1은 음극선관의 벌브를 지시한다. 상기 음극선관의 패널과 펀늘의 봉착부위에는 도체 금속으로 된 방폭보강밴드(2)가 장착되어 있다. 이 방폭보강밴드(2)는 음극선관이 세트에 조립된 상태에서 세트에 접지된다. 한편, 상기 음극선관 패널의 화면부 외면에는 도전성 물질이 포함된 코팅막(3)이 도포되어 있다.Reference numeral 1 designates a bulb of the cathode ray tube. An explosion-proof reinforcing band 2 made of a conductive metal is mounted on the sealing portion of the panel and the funnel of the cathode ray tube. The explosion-proof reinforcing band 2 is grounded to the set with the cathode ray tube assembled to the set. On the other hand, the outer surface of the screen portion of the cathode ray tube panel is coated with a coating film 3 containing a conductive material.
본 고안에 따르면 전술한 접지 방폭보강밴드(2)와 코팅막(3) 사이에는 상부에서 중접이 이루어지도록 도전성 물질로 코팅한 도전물질 도포부(4)를 형성한다. 전술한 도전물질 도포부(4)는 정전기 제거를 위해 적당한 면적으로 형성하는 것이 필요하다.According to the present invention, a conductive material coating part 4 coated with a conductive material is formed between the above-described ground explosion-proof reinforcing band 2 and the coating film 3 so as to be in contact with the top. The conductive material applying portion 4 described above needs to be formed in a suitable area for removing static electricity.
전술한 본 고안의 구성에 따르면, 음극선관을 동작시키는 경우 전자빔이 음극선관 패널의 화면부 내면에 충돌하고 이에 따라 음극선관 패널의 화면부 외면에 + 정전기가 발생하며 이때 발생한 정전기는 코팅막(3)과 도전된 도전물질 도포부(4)를 통해 신속하며 확실하게 방폭보강밴드(2)로 흘러서 제거된다.According to the above-described configuration of the present invention, when operating the cathode ray tube, the electron beam impinges on the inner surface of the screen portion of the cathode ray tube panel, and thus + static electricity is generated on the outer surface of the cathode portion of the cathode ray tube panel. The conductive material is applied to the conductive part 4 and quickly and reliably flows into the explosion-proof reinforcing band 2 and is removed.
전술한 구성과 작용을 가진 본 고안의 음극선관에 따르면, 취급시에 도전부가 용이하게 이탈되지 않는 한편 도전부에 일부 손실이 있는 경우에라도 정전기 제거에 큰 문제가 없으며 또한 음극선관 패널의 화면부 외면에 발생한 정전기를 신속하며 확실하게 제거해줄 수 있게 해준다.According to the cathode ray tube of the present invention having the above-described configuration and operation, even if the conductive portion is not easily separated during handling, there is no big problem in removing static electricity even if there is some loss in the conductive portion, and also the outer surface of the screen portion of the cathode ray tube panel It can quickly and reliably remove the static electricity generated in.
