본 고안은 음극선 관내를 배기시킨후에 남게되는 잔류가스를 제거하기 위하여 음극선관의 내부에 장착되는 가스흡작장치에 관한 것으로, 보다 상세하게는 바륨(Ba)등으로 이루어진 게터(Getter)가 음극선관내의 잔류산소에 의해 연소될 때 이 게터로부터 바륨이 확산되는 각도를 적절히 변경시켜 줌으로써, 패널내부의 형광면이 손상되는 것을 방지할 수 있도록 개선된 음극선관의 가스흡작장치에 관한 것이다.The present invention relates to a gas suction device mounted inside the cathode ray tube in order to remove residual gas remaining after exhausting the inside of the cathode ray tube. More specifically, a getter made of barium (Ba) or the like is used in the cathode ray tube. The present invention relates to a gas suction device of an improved cathode ray tube that can be prevented from damaging the fluorescent surface inside a panel by suitably changing the angle at which barium diffuses from this getter when burned by residual oxygen.

전자총에서 방사되는 전자빔을 형광면위에 주사함으로써 화상을 표시하는 종래의 음극선관은 외관적으로 볼때 제1도 내지 제3도에 도시된 바와 같이 형광면(1)이 내설된 패널부(2)와, 깔대기 모양의 퍼넬부(3) 및 네크부(4)로 이루어지고, 상기 네크부(4)내에는 전자총구체(5)가 장착된 구조로 되어있다.The conventional cathode ray tube which displays an image by scanning an electron beam emitted from an electron gun onto a fluorescent surface has a panel portion 2 having a fluorescent surface 1 embedded therein as shown in FIGS. It consists of the funnel part 3 and the neck part 4 of the shape, and the neck part 4 has the structure in which the electron muzzle body 5 was mounted.

상기 전자총구체(5)의 구조를 별도로 설명하면, 이는 제2도에 도시된 바와같이 전자총(6)과, 이 전자총(6)의 선단에 설치되는 콘버젼스부(7) 및 이 콘버젼스부(7)의 주위에 연결되어 전자총구체(5)를 네크부(4) 내벽에 고정하는 도전성 고정스프링(8)으로 구성된다.The structure of the electron gun barrel 5 will be described separately, as shown in FIG. 2, which is an electron gun 6, a convergence part 7 provided at the tip of the electron gun 6, and this convergence part ( It is composed of a conductive fixed spring 8 connected to the periphery of 7) to fix the electron muzzle body 5 to the inner wall of the neck portion 4.

한편, 상기 콘버젼스부(7)의 주위에는 상기 도전성 고정스프링(8)과 함께 퍼넬부(3)의 내벽을 따라 연장설치되는 게터지지체(19)가 연결되고, 이 게터지지체(19)의 선단에는 함체(20')에 담겨지는 바륨물질로 이루어진 게터(21)가 삽입장착되어 있다. 이 게터(21)는 관내부의 기체를 배기시킨후에 외부로부터 인가되는 고주파 유도가열에 의해 연소되어 관내로 확산되어서 잔류하는 산화성가스를 화학적으로 흡착제거하는 작용을 한다.On the other hand, a getter support 19 which extends along the inner wall of the funnel portion 3 together with the conductive fixing spring 8 is connected to the periphery of the convergence portion 7, and the tip of the getter support 19 is connected. The getter 21 made of a barium material contained in the housing 20 'is inserted and mounted. The getter 21 serves to chemically adsorb and remove the remaining oxidizing gas which is burned by high frequency induction heating applied from the outside after the gas inside the tube is exhausted and diffused into the tube.

그러나 2인치 내지 7인치의 소형음극선관에 있어서는 게터(21)가 그 내부에 장착되는 상기 퍼넬부(3)가 상기패널부(2)의 형광면에 근접해서 위치하기 때문에 게터(21)가 연소될 때, 바륨물질이 형광면에 닿게되어 형광면상에 흑점을 발생시켜 불량품의 음극선관이 된다고하는 문제점이 발생하였다.However, in the small cathode ray tube of 2 inches to 7 inches, the getter 21 is burned because the funnel portion 3 on which the getter 21 is mounted is located close to the fluorescent surface of the panel portion 2. At this time, a problem arises that the barium material is brought into contact with the fluorescent surface to generate black spots on the fluorescent surface, resulting in a poor quality cathode ray tube.

그리고 제3도(a) 및 (b)와 같이 구성된 종래의 가스흡착장치를 2인치 내지 7인치의 소형음극선관에 장착하면 제3도(b)에 도시한 바와 같이 전자빔의 편향각도에 관계없이 게터지지체(19)와, 이 지지체(19)상에 정착되는 함체(20')의 외주연부(22)와는 수직(90°)을 이루고 있으로, 이 상태에서 함체(20')내에 담겨있는 게터(21)를 고주파유도로 가열시키게 되면 상기 게터(21)가 연소되면서 대향방향으로 확산되게 되고, 이때 상기 게터(21)의 구성물질인 바륨 일부가 인접된 형광면에 닿게되어 그 형광면 일부가 흑화되는 문제점도 발생시키게 된다.When the conventional gas adsorption device configured as shown in FIGS. 3A and 3B is mounted on a small cathode ray tube of 2 inches to 7 inches, regardless of the deflection angle of the electron beam as shown in FIG. The getter support 19 is perpendicular to the outer periphery 22 of the enclosure 20 'fixed on the support 19, and thus the getter contained in the enclosure 20' in this state. When the 21 is heated at a high frequency induction, the getter 21 is combusted and diffused in opposite directions. At this time, a part of the barium, which is a constituent of the getter 21, comes into contact with an adjacent fluorescent surface, and the fluorescent surface is partially blackened. It will also cause problems.

따라서, 본 고안은 상기와 같은 종래의 여러가지 문제점을 해결하기 위하여 안출된 것으로, 본 고안의 목적은 게터가 연소될때 게터의 확산각도를 적절히 변경시켜 줌으로써 불순물이 형광면에 닿지 못하도록 개선한 음극선관의 가스흡착장치를 제공하는데 있다.Accordingly, the present invention has been devised to solve various problems of the related art, and an object of the present invention is to improve the diffusion angle of the getter when the getter is burned so that impurities do not come into contact with the fluorescent surface. It is to provide an adsorption device.

상기와 같은 목적을 달성하기 위한 본 고안의 전자총의 콘버젼스부에 연결된 게터지지체의 전면부상에 바륨등의 게터를 담는 함체의 외주연부를 따른 접선과, 상기 외주연부와 게터지지체가 만나는 지점을 통과하며 상기 게터지지체에 대한 수직선이 이루는 각도((여기서는 편향각도를 나타냄)을 유지하도록된 것을 특징으로 한다.Passing through the tangent along the outer periphery of the housing containing a getter such as barium on the front of the getter support connected to the convergence part of the electron gun of the present invention for achieving the above object, and the point where the outer periphery and the getter support meet And an angle formed by a vertical line with respect to the getter support (here Denotes a deflection angle).

상기와 같은 구성의 본 고안에 의하면, 2내지 7인치의 소형음극선관에 있어서 제품별로 규격화된 전자빔의 편향각도에 맞추어 함체의 외주면부의 경사각도를 맞추어서 제조해서 게터지지체에 용융고착시킴으로써 상기 함체에 담긴 게터가 가열에 의해 비산된 때에 형광면에 부착되지 않아 형광면이 부분적으로 흑화되는 종래 문제점을 해결할수 있다.According to the present invention of the configuration as described above, in the small cathode ray tube of 2 to 7 inches manufactured by adjusting the inclination angle of the outer peripheral surface portion of the housing according to the deflection angle of the electron beam standardized for each product and melt-fixed to the getter support body contained in the housing The conventional problem is that the getter does not adhere to the fluorescent surface when scattered by heating and the fluorescent surface partially blackens.

이하, 본 고안의 일실시예에 대하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제4도는 본 고안에 따른 가스흡착장치의 설치상태도이고, 제5도(a) 및 (b)는 본 고안의 가스흡착장치의 정면도 및 단면도이다.Figure 4 is a state diagram of the gas adsorption device according to the present invention, Figure 5 (a) and (b) is a front view and a cross-sectional view of the gas adsorption device of the present invention.

본 고안의 가스흡착장치는 상기 종래의 가스흡착장치와는 달리 전자빔의 편향각도()에 맞추어서 함체(20)의 외주연부(12)의 접선(T)과 상기 함체(20)의 외주연부(12)와 게터지지체(19)가 만나는 지점을 통과하며 상기 게터지지체(19)에 대한 수직선(L)이 이루는 각도(θ)가 편향각도()가 되도록 함체(20)를 제조한 후, 게터지지체(19)에 이 함체(20)를 레이저용접에 의해 고착시킨다. 그 후에 함체(20)내에 게터(11)를 담은 다음, 게터지지체(19)의 일측을 콘버젼스부(7)에 고착하여 제4도에 도시한 바와 같이 고정한다.Gas adsorption device of the present invention is different from the conventional gas adsorption device of the deflection angle of the electron beam ( The tangent T of the outer periphery 12 of the enclosure 20 and the point where the outer periphery 12 of the enclosure 20 meets the getter support 19 and with respect to the getter support 19 The angle θ formed by the vertical line L is the deflection angle ( After the enclosure 20 is manufactured to be), the enclosure 20 is fixed to the getter support 19 by laser welding. Thereafter, the getter 11 is contained in the enclosure 20, and then one side of the getter support 19 is fixed to the convergence portion 7 and fixed as shown in FIG.

따라서, 상기 종래의 가스흡착장치는 달리 전자빔의 편향각도()에 따라 게터지지체(19)의, 법선연장선(L)과, 상기 지지체(19)상에 장착되는 함체(20)의 외주연부(12)를 따라 취한 접선(T)이 이루는 형성각도Therefore, in the conventional gas adsorption device, the deflection angle of the electron beam ( Forming angle formed by the normal extension line L of the getter support 19 and the tangent T taken along the outer periphery 12 of the enclosure 20 mounted on the support 19.

(θ)가 (θ=(여기서전자빔의 편향각도를 나타냄)이 된다.(θ) is (θ = (here The deflection angle of the electron beam).

즉, 실험에 의하면 게터지지체(19)의 법선성분(L)과 함체 외주연부(12)를 따라서 취한 접선(T)이 이루는 각도(θ를에서 부터의 범위에 설정하는 것이 가장바람직하게 되나, 상기 적절범위를 벗어나 θ가 작게되면 게터(11)의 연소물질이 형광면에 직접 닿게되어 형광면의 흑화현상을 발생시키고 θ가 크게되면 고주파 유도가열방식에 의해서는 상기 게터(11)를 연소시키기가 곤란하게 된다.That is, according to the experiment, the angle θ formed between the normal component L of the getter support 19 and the tangent T taken along the outer periphery 12 of the housing 12 is determined. From It is most preferable to set in the range of, but if the θ becomes smaller than the appropriate range, the combustion material of the getter 11 directly contacts the fluorescent surface, causing blackening of the fluorescent surface, and when the θ is large, the high frequency induction heating method is used. It is difficult to burn the getter 11.

이와같이 본 고안은 게터지지체의 법선성분과 게터를 담고 있는 함체 외주연부를 따라 취한 접선이 이루는 각도를 전자빔의 편향각도에 맞추어 함체를 꼭지부가 절격된 역원추형상으로 제조해서 게터지지체에 함체를 용융고착시킨후, 함체내에 게터를 끼워고정함으로써, 게터의 연소물질이 직접 형광면에 닿아서, 게터와 접속된 화면의 일부가 흑화되는 것을 방지할 수 있고, 또 고주파 유도가열이 용이하게 일어날 수 있다는 효과가 있다.As such, the present invention manufactures the enclosure in the shape of an inverted cone of the tip of the getter support according to the deflection angle of the electron beam according to the deflection angle of the electron beam according to the normal angle of the getter support and the angle taken along the outer periphery of the enclosure containing the getter. By inserting the getter into the enclosure, the getter's combustion material directly touches the fluorescent surface to prevent blackening of a part of the screen connected to the getter, and the high frequency induction heating can be easily performed. There is.
