Abstract

본 고안은 음극선관의 개선된 방폭밴드를 개시한다.The present invention discloses an improved explosion proof band of a cathode ray tube.

종래에는 방폭밴드와 러그가 별도로 구성되었으므로 제작이 번잡할 뿐 아니라 러그를 방폭밴드의 소정위치에 정확히 위치시키기도 대단히 어려웠다.In the related art, since the explosion-proof band and the lug are separately configured, not only is it complicated to manufacture, it is also very difficult to accurately position the lug at a predetermined position of the explosion-proof band.

본 고안에서는 방폭밴드의 네 모서리에 방사상으로 연장되는 복수의 이어를 구비하여, 이를통해 음극선관을 화상장치에 고정함으로써 종래의 문제를 해결하였다. (제2도)The present invention solves the conventional problem by providing a plurality of ears extending radially at the four corners of the explosion-proof band, thereby fixing the cathode ray tube to the image device. (Figure 2)

본 고안은 음극선관(陰極線管)에 관한 것으로, 더 상세히는 패널(panel) 외주에 밴딩(banding)되어 이를 보강하는 방폭밴드(防爆 band)에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly, to an explosion-proof band that is banded on the outer periphery of a panel to reinforce it.

제1도에서, 음극선관(T)은 전자빔(electron beam)의 안정적 발생과 가속 등을 위해 그 내부가 고진공상태로 제조된다. 이에따라 음극선관(T)은 점선으로 도시한 바와같이 외부의 대기압과의 압력차에 의해 패널(P)과 펀넬(funnel; F)이 압축되고 패널(P)의 스커어트(skirt; S)가 외측으로 팽창하는 큰 변형응력 상태에 놓이게 된다. 이와같은 변형은 정상적인 상태라면 자체강도에 의해 지탱될 수 있으나, 음극선관(T)에 흠이 있다거나 외부로부터 충격이 가해지는 경우 등에는 크랙(crack)이 신속히 전파되어 음극선관(T)이 폭축(implosion)되는 문제가 발생된다. 이에따라 패널(P)의 스커어트(S) 외주에는 방폭밴드(B)를 소정의 인장력으로 감아줌으로써 패널(P) 스커어트(S)의 팽창을 억제하여 음극선관(T)을 보강하고 있다.In FIG. 1, the cathode ray tube T is manufactured in a high vacuum state in order to stably generate and accelerate an electron beam. Accordingly, the cathode ray tube T is compressed by the pressure difference between the external atmospheric pressure as shown by the dotted line, and the panel P and the funnel F are compressed and the skirt S of the panel P is outside. As a result, they are in a state of large strain stresses. Such deformation may be supported by its own strength if it is in a normal state, but if the cathode ray tube T is damaged or an impact is applied from the outside, a crack propagates rapidly and the cathode ray tube T is deflated. (implosion) problem occurs. As a result, the explosion-proof band B is wound on the outer periphery of the panel P with a predetermined tensile force, thereby suppressing the expansion of the panel P skirt 2 and reinforcing the cathode ray tube T.

이러한 방폭밴드(B)는 인장력의 제공방법에 따라 인장(tension)방식과 열수축(shrinkage)방식으로 대별된다.The explosion-proof band (B) is roughly divided into a tension (tension) method and a heat shrink (shrinkage) method according to the method of providing the tensile force.

한편 패널(P)의 스커어트(S)네 모서리에는 음극선관(T)을 화상장치내에 고정하기 위한 러그(lug; L)가 구비되는데, 이는 패널(P)과 방폭밴드(B)간에 개재되거나 도시한 바와같이 방폭밴드(B)에 용접된다. 특히 방폭밴드(B)를 가열 팽창시킨 뒤, 패널(P)에 씌워 냉각시킴으로써 인장력을 제공하는 열수축방식의 방폭밴드(B)에는 후자의 방법을 사용할 수 밖에 없다.On the other hand, lugs (L) for fixing the cathode ray tube (T) in the image device are provided at four corners of the skirt (S) of the panel (P), which is interposed between the panel (P) and the explosion-proof band (B). As shown, it is welded to the explosion-proof band B. FIG. In particular, the latter method can only be used for the heat-shrink-proof explosion-proof band B which provides a tensile force by heating and expanding the explosion-proof band B and then covering the panel P with cooling.

그런데 이러한 종래의 구성은 러그(L)가 방폭밴드(B)와 별도로 구성되어 용접되므로 제작이 번잡할 뿐 아니라 공수와 원가가 상승하는 문제가 있었다. 또한 러그(L)를 방폭밴드(B)에 접합하기 위해서는 이들을 지지하는 별도의 지그(jig)등이 필요하게 되고, 각 러그(L)를 정확한 위치에 접합하기가 대단히 어려운 문제도 있었다.However, the conventional configuration has a problem that the lug (L) is configured separately from the explosion-proof band (B) and welded, so that manufacturing is not only complicated but also the cost and cost are increased. In addition, in order to join the lug L to the explosion-proof band B, a separate jig for supporting them is required, and there is a problem that it is very difficult to join each lug L to the correct position.

본 고안의 목적은 상술한 종래의 문제들을 감안하여 별도의 러그 없이도 음극선관을 화상장치내에 고정 지지할 수 있는 방폭밴드를 제공하는 것이다.It is an object of the present invention to provide an explosion-proof band which can fix and support a cathode ray tube in an image device without a separate lug in view of the above-described conventional problems.

이와같은 목적을 달성하기 위해 본 고안에 의한 음극선관의 방폭밴드는 음극선관의 패널 외주에 소정의 인장력으로 밴딩되어 폭축을 방지하는 방폭밴드에 있어서, 그 네 모서리에 방사상으로 연장되어 화상장치에 고정되는 복수의 이어가 구비되는 것을 특징으로 한다.In order to achieve the above object, the explosion-proof band of the cathode ray tube according to the present invention is a explosion-proof band which is bent at a predetermined tensile force on the outer periphery of the panel of the cathode ray tube to prevent the explosion. Characterized in that a plurality of ears are provided.

이에따라 본 고안은, 별도의 러그를 구비하지 않고서도 음극선관을 화상장치에 고정할 수 있게 되므로 음극선관의 제작공수와 원가절감 및 생산성 향상등에 효과를 발휘한다.Accordingly, the present invention is able to fix the cathode ray tube to the image apparatus without providing a separate lug, thereby exhibiting an effect on manufacturing man-hours, cost reduction, and productivity improvement of the cathode ray tube.

이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도에서, 본 고안에 의한 음극선관의 방폭밴드(B)는 소정폭으로 구성된 띠 형태의 판재를 복수 절곡하여 대략 직사각형 형태로 구성한 뒤, 밴드의 양 단부(D1,D2)상에 겹판(lap plate; A)을 겹쳐 이 겹판(A)과 밴드의 양 단부(D1,D2)를 저항용접(resistance welding)함으로써 구성된다.In Figure 2, the explosion-proof band (B) of the cathode ray tube according to the present invention is formed in a substantially rectangular shape by bending a plurality of strip-shaped plate material having a predetermined width, and then laminated on both ends (D1, D2) of the band ( A lap plate (A) is stacked to resist weld the laminate (A) and both ends (D1, D2) of the band.

이와같이 구성된 방폭밴드(B)의 네 모서리 상부에는 본 고안의 특징에 따라 화상장치에 고정되는 복수의 이어(ear; E)가 방사상으로 연장되어 형성된다. 각 이어(E)에는 화상장치에의 고정을 위해 세트스크류(set screw)등이 관통하는 관통구멍(hole; H)이 형성된다.The upper four corners of the explosion-proof band (B) configured as described above are formed by extending radially a plurality of ears (E) fixed to the image device according to the features of the present invention. Each ear E is provided with a through hole H through which a set screw or the like penetrates to the image device.

한편 이와같은 본 고안 방폭밴드(B)의 바람직한 한 제작방법을 제3도를 참조하여 살펴보기로 한다.Meanwhile, a preferred manufacturing method of the present invention explosion-proof band (B) will be described with reference to FIG. 3.

먼저(a)에 도시한 바와같이 판재를 소정의 형상으로 블랭킹(blanking)하여 밴드와 그 소정위치에 복수의 이어(E)를 돌출되게 구성시킨다. 다음 이 밴드를 복수 절곡하여 (b)에 도시한 바와같이 각 이어(E)가 그 모서리의 연장선상에 위치되도록 직사각형 형태로 구성한 뒤, 밴드의 양 단부(D1,D2)상에 겹판(A)을 대고 이 겹판(A)과 밴드의 양 단부(D1,D2)를 저항용접한다. 다음 (c)에 도시한 바와같이 각 이어(E)를 외측방으로 직각절곡함으로써 본 고안 방폭밴드(B)를 구성하게 된다.First, as shown in (a), the plate is blanked in a predetermined shape so as to protrude a plurality of ears E at the band and its predetermined position. Next, a plurality of the bands are bent to form a rectangular shape such that each ear (E) is positioned on an extension line of the edge thereof, as shown in (b), and then the laminate (A) is formed on both ends (D1, D2) of the band. The laminate A is subjected to resistance welding of both ends D1 and D2 of the band. Next, as shown in (c), each ear (E) is bent at right angles to the outside to constitute the inventive explosion-proof band (B).

이와같이 구성된 본 고안 방폭밴드(B)는 열수축방식에 의한 음극선관의 패널 외주에 밴딩되어 그 폭축을 방지하게 되며, 각 모서리부에 구비된 이어(E)를 통해 음극선관을 화상장치내에 고정하게 된다. 이에따라 종래와 같이 별도의 러그를 구비할 필요가 없게 되므로 용접등 그에 따른 제작공수를 줄일 수 있으며, 각 이어(E)가 소정의 위치에 정확히 위치하게 되므로 종래와 같이 번잡하고 어려운 정합작업 없이도 음극선관을 화상장치의 정확한 위치에 고정시킬 수 있게 된다.The explosion-proof band (B) of the present invention configured as described above is bent on the outer circumference of the panel of the cathode ray tube by the heat shrink method to prevent its shrinkage, and the cathode ray tube is fixed to the image device through the ears (E) provided at each corner portion. . Accordingly, it is not necessary to provide a separate lug as in the prior art, thereby reducing the manufacturing maneuver due to welding and the like. Since each ear (E) is precisely positioned at a predetermined position, the cathode ray tube can be made without complicated and difficult matching work as in the prior art. Can be fixed at the correct position of the image device.

따라서 본 고안은 음극선관의 원가절감 및 생산성 향상 등에 효과가 있다.Therefore, the present invention is effective in reducing the cost and productivity of the cathode ray tube.
