Abstract

본 고안은 음극선관의 개선된 대전방지용 테이프를 개시한다.The present invention discloses an improved antistatic tape of a cathode ray tube.

종래에는 패널표면과 방폭밴드에 연결부착된 도전성 테이프가 작업자의 부주의로 인한 긁힘이나 음극선관을 세트에 장착시 방폭밴드의 미동으로 인해 박형의 테이프가 쉽게 찢어지게 되어 패널표면의 대전된 전하를 접지시키지 못하는 문제가 있었다.Conventionally, the conductive tape attached to the panel surface and the explosion-proof band is easily broken due to the operator's careless scratches or the installation of the cathode ray tube on the set. There was a problem that could not be.

본 고안에서는 도전성 테이프 일축에 비닐을 코팅하므로 그 강도를 향상시키게 되어 상술한 이유로도 찢어짐이 방지되어 종래의 문제를 해결하였다.In the present invention, since the vinyl is coated on the conductive tape uniaxially, the strength thereof is improved, and tearing is prevented even in the above-described reason, thereby solving the conventional problem.

본 고안은 음극선관(陰極線管)에 관한 것으로, 더 상세히는 음극선관의 대전방지(Anti Static)용 도전성 테이프(conductive tape)에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly, to an anti static conductive tape of a cathode ray tube.

일반적으로 브라운관(braun tube)으로 불리며 화상표시장치의 주종을 이루고 있는 음극선관은 제1도에 도시된 바와 같이 네크(neck; N)에 설치된 전자총(electron gun; G)에서 발사된 전자빔(electron beem; B)을 도시되지 않은 편향수단에 의해 패널(panel; P)내면의 형광면(S)에 선택적으로 랜딩(landing)시켜 발광시킴으로써 화상을 표시하게 된다.The cathode ray tube, which is generally referred to as a brown tube and constitutes the dominant type of an image display device, is an electron beam emitted from an electron gun G installed in a neck N as shown in FIG. B) is selectively landed on the fluorescent surface S of the inner surface of the panel P by deflecting means (not shown) to emit light.

그런데 이러한 음극선관에 있어서는 전자빔(B)의 가속을 위해 패널(P) 내면에 아노드(anode; A2)를 통해 수십KV의 고전압을 인가해 주게 된다. 이때 발생되는 정전하는 음극선관의 작동중에는 거의 발생하지 않지만 음극선관의 ON-OFFT시에는 이러한 정전하가 다량 발생하여 패널(P)표면에 양 또는 음전위로 대전된다.In the cathode ray tube, a high voltage of several tens of KV is applied to the inner surface of the panel P through the anode A2 to accelerate the electron beam B. The static electricity generated at this time is hardly generated during operation of the cathode ray tube, but during the ON-OFFT of the cathode ray tube, a large amount of such static charge is generated and is charged to the panel P surface with a positive or negative potential.

이와 같이 대전된 전하, 즉 정전기의 전위는 10KV이상이 되어 사용자가 접촉하는 경우 전기적 충격을 주게 될 뿐 아니라, 외부공기중에 존재하는 먼지 등의 대전입자를 흡착하여 패널(P)표면에 부착시킴으로써 화면의 선명도를 저하시키게 된다.Thus, the charged electric charge, that is, the potential of static electricity is 10KV or more, so that when the user touches it, it not only gives an electric shock but also adsorbs charged particles such as dust in the outside air and attaches it to the surface of the panel P. The sharpness of the will be reduced.

이와 같은 정전기 문제를 해결하기 위해 종래에는 제2도의 (a)와 같이 이 패널(P)의 표면에 도전성 물질을 분산시킨 대전방지막(Anti Static Coating; A)을 형성하여 대전된 전하(電荷)를 접지하도록 하고 있는바, (b)와 같이 패널(P)의 대전방지막(A)과 방폭밴드(B)의 러그(lug; L) 등에 접지선을 연결하고 있다.In order to solve the electrostatic problem, as shown in FIG. 2A, an antistatic film (A) in which a conductive material is dispersed is formed on the surface of the panel (P) to charge an electric charge. As shown in (b), the ground wire is connected to the antistatic film A of the panel P, the lug L of the explosion-proof band B, and the like.

그런데 이러한 도전성 테이프(T)는 통상적으로 도전성인 은박지(銀箔紙)로 이루어 지는바, 패널(P)의 스커어트와 방폭밴드(B)외주에 부착된 테이프(T)는 작업자의 부주의로 공구등으로 약간만 긁혀도 찢어져서 단절되고, 특히 음극선관을 세트에 장착시 방폭밴드(B)의 미동으로 인해 박형의 테이프(T)가 쉽게 손상되어 패널(P)표면의 대전된 전하를 접지시킬수 없게 되는 문제가 있다.By the way, such a conductive tape (T) is usually made of a conductive silver foil (bar), the tape (T) attached to the outer periphery and the explosion-proof band (B) of the panel (P) is inadvertently used by tools, etc. Even if only a few scratches can be torn and disconnected, especially when the cathode ray tube is mounted on the set, the thin tape (T) is easily damaged by the movement of the explosion-proof band (B), so that the charged charge on the surface of the panel (P) cannot be grounded. There is.

상술한 문제를 감안하여 본 고안의 목적은 외부의 충격이나 방폭밴드의 미동에도 테이프가 손상되지 않아 패널표면과 방폭밴드와의 도전을 확실하게 한 음극선관의 대전방지용 테이프를 제공하는 것이다.In view of the above problems, an object of the present invention is to provide an antistatic tape of a cathode ray tube, which ensures the conductive surface between the panel surface and the explosion-proof band without damage to the tape even when external shocks or explosion of the explosion-proof band occur.

이와 같은 목적을 달성하기 위한 본 고안은 패널의 대전방지막과 방폭밴드 외주에 연결부착되어 패널에 대전된 전하를 접지시키기 위한 음극선관의 대전방지용 테이프에 있어서, 연질의 합성수지가 구비되는 것을 특징으로 한다.The present invention for achieving the above object is characterized in that in the antistatic tape of the cathode ray tube for grounding the charge charged to the panel is attached to the antistatic film and the explosion-proof outer periphery of the panel, characterized in that the soft synthetic resin is provided .

본 고안의 구체적 특징들 및 이점들은 첨부된 도면을 참조한 이하의 설명으로 더욱 명확해 질 것이다.Specific features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

제3도의 (a)에서, 음극선관의 일반적인 구성 및 작동은 종래와 동일하므로 이에 대한 중복설명은 생략하고 본 고안의 특징에 대해서만 설명한다.In Figure 3 (a), since the general configuration and operation of the cathode ray tube is the same as in the prior art, the duplicate description thereof will be omitted and only the features of the present invention will be described.

아노드(A2)를 통해 인가된 고압으로 인해 패널(P)표면이 양 또는 음전위로 대전되는 것을 방지하기 위해 패널(P)표면에 대전방지막(A)이 도포되어 있고, 이와 방폭밴드(B)간에 도전성테이프(T)가 부착되어 있다. 이 도전성 테이프(T)는 통상 은박으로써 그 일면에 접착부(K)가 구비되고 타면에 본 고안의 특징에 따라 합성수지가 부착되어 있다. 이 합성수지는 박형의 비닐(V)로 구비되는바, 종이나 은박 등에 코팅(coating)되어 찢어지기 쉬운 재료를 보호하게 된다. 그 예로써, 껌을 감싸는 껌종이의 내피는 은박에 비닐이 코딩되어 은박의 강도를 보완하여 구비되어 있고, 공책의 겉표지와 같이 두꺼운 종이에 비닐이 코팅되어서 공책을 장시간 사용하여도 그 회손을 최소화하도록 되어 있다.An antistatic film (A) is applied to the surface of the panel (P) to prevent the surface of the panel (P) from being charged to the positive or negative potential due to the high pressure applied through the anode (A2), and explosion-proof band (B) The conductive tape T is attached to the inside. The conductive tape T is usually silver foil, and the adhesive portion K is provided on one surface thereof, and synthetic resin is attached to the other surface according to the characteristics of the present invention. The synthetic resin is provided with a thin vinyl (V), which is coated with paper or silver foil to protect a material that is easily torn. For example, the inner surface of the gum paper that surrounds the gum is provided with vinyl-encoded silver foil to complement the strength of the silver foil, and the vinyl paper is coated on a thick paper like the cover of the notebook, so that even if the notebook is used for a long time, It is intended to be minimal.

이와 동일하게 박형의 도전성 테이프(T)의 일면에 코팅된 비닐(V)은 테이프(T)의 강도를 향상시키게 되어 외부의 충격이나 음극선관을 세트에 장착시 방폭밴드(B) 유동에도 도전성 테이프(T)가 쉽게 찢어지지 않으므로 패널(P)외면에 대전된 전하를 확실하게 접지시킬수 있게 된다.Likewise, the vinyl (V) coated on one surface of the thin conductive tape (T) improves the strength of the tape (T), so that the conductive tape is protected against the flow of the explosion-proof band (B) when an external shock or a cathode ray tube is mounted on the set. Since (T) is not easily torn, it is possible to reliably ground the electric charges charged on the outer surface of the panel (P).

이상에서와 같은 본 고안의 음극선관의 대전방지용 테이프는 대전된 전하가 확실하게 접지되어 패널에 먼지 등의 대전입자가 흡착되지 않아 선명도를 향상시킬수 있게 되고 사용자의 감전을 방지할 수 있는 효과가 있다.As described above, the antistatic tape of the cathode ray tube of the present invention can be surely grounded so that charged particles such as dust are not adsorbed on the panel, thereby improving clarity and preventing electric shock of the user. .
