본 고안은 음극선관의 보강밴드에 관한 것으로서, 더욱 상세하게는 음극선관의 보강효과를 최대로 하기 위해 체결되는 보강밴드로서 고진공시 발생되는 음극선관의 응력을 최소화 할 수 있으며, 외부충격으로 인한 음극선관의 폭축을 방지할 수 있도록 한 것이다.The present invention relates to a reinforcing band of a cathode ray tube, and more particularly, a reinforcing band fastened to maximize the reinforcing effect of the cathode ray tube, which can minimize the stress of the cathode ray tube generated during high vacuum, and the cathode ray due to external impact. It is to prevent the tube from being deflated.

일반적으로, 음극선관은 제1도에 나타낸 바와 같이 판넬(2)내벽에 적, 녹, 청색의 형광체(4)가 도포되고, 전자총(5)에서 방출된 전자빔은 편향요크(6)에 의해 편향되어 새도우마스크(7)의 구멍을 통하여 상기 판넬(2)의 내벽에 도포된 형광체(4)에 도달되며, 새도우마스크(7)와 지자재를 차폐하는 인너쉴드(8)를 지지하는 프레임(9)은 판넬(2)에 고정된다.In general, the cathode ray tube is coated with red, green, and blue phosphors 4 on the inner wall of the panel 2, and the electron beam emitted from the electron gun 5 is deflected by the deflection yoke 6, as shown in FIG. And reaches the phosphor 4 coated on the inner wall of the panel 2 through the hole of the shadow mask 7, and supports the inner shield 8 that shields the shadow mask 7 and the earth material. ) Is fixed to the panel 2.

판넬(2)과 펀넬(3)은 프릿 글래스(Feit Glass)(10)으로 융착되고, 음극선관의 내부는 10-7 토프(Torr)정도의 고진공상태이므로 외부에서 충격이 발생시 음극선관이 폭축되어 큰 위험을 초래하게 된다.The panel 2 and the funnel 3 are fused with frit glass 10, and the inside of the cathode ray tube is in a high vacuum state of about 10-7 torr, so that the cathode ray tube is deflated when an external shock occurs. There is a great danger.

그러므로, 폭축을 방지하기 위하여 음극선관에 판넬(2)의 스커트부에 보강밴드(1a)를 체결하여 음극선관에서 고진공시 발생되는 인장 및 압축응력을 감소시켜 보강하게 된다.Therefore, the reinforcing band 1a is fastened to the skirt portion of the panel 2 to the cathode ray tube in order to prevent the shrinkage, thereby reducing the tensile and compressive stress generated during high vacuum in the cathode ray tube to reinforce it.

한편, 판넬(2)의 스크트부에서 발생되는 응력은 제2도에 나타낸 바와 같이, 판넬스커트부의 위치에 따라 응력의 크기가 다르며, 판넬(2)의 바텀(Bottom)부와 스커트부(또는 쉘부)의 이음부인 몰드매치(Mold Match)선에서 가장 큰 인장응력이 발생함에 따라 응력이 큰 부위는 보강밴드의 두께를 두껍게 하여 음극선관에 인가하는 힘을 크게 하고, 응력이 작은 부위는 상대적으로 보강밴드의 두께를 얇게 해야만 효과적이다.On the other hand, the stress generated in the scutting portion of the panel 2, as shown in Figure 2, the magnitude of the stress varies depending on the position of the panel skirt portion, the bottom (bottom) and skirt (or shell portion) of the panel 2 As the largest tensile stress occurs at the mold match line, which is the joint part of), the large stressed part thickens the thickness of the reinforcing band to increase the force applied to the cathode ray tube, and the small stressed part is relatively reinforced Only a thin band is effective.

따라서 제3도 (a)와 같은 일자형의 보강밴드(1a)는 상기와 같은 요구에 부응하지 못한다.Therefore, the straight reinforcing band 1a as shown in FIG. 3 (a) does not meet the above requirements.

또한 응력이 크게 작용하는 부위에 보강밴드 두께를 두껍게 하기 위해 제3도 (b)와 같은 겹침형 보강밴드(1b)가 사용되고 있으나, 이러한 겹침형 보강밴드는 단순히 일자형의 보강밴드를 일정길이만큼 겹쳐서 형성한 것이기 때문에 응력 크기 변화에 따른 두께변화가 되지 않아 응력을 감소시키는데 한계가 있고 따라서 확실한 보강효과를 낼 수 없음은 물론 보강밴드의 두께를 필요 이상 두께를 두껍게 해야 하므로 재료비가 상승되었다.In addition, the overlapped reinforcement band 1b as shown in FIG. 3 (b) is used to increase the thickness of the reinforcement band at the place where stress is largely applied. However, the overlapped reinforcement band simply overlaps the straight reinforcement band by a certain length. Because it is formed, there is a limit in reducing the stress due to the change in thickness due to the change in stress size. Therefore, the material cost is increased because the thickness of the reinforcing band needs to be thickened more than necessary.

또한 겹침형 보강밴드(1b)는 겹치는 부윙 사이뜸(틈새)이 발생하기 쉽고 이러한 경우 보강밴드의 가열시 열전달 차이가 생겨 보강밴드가 안쪽으로 휘어지는 현상이 나타나 보강밴드 체결시 작업성이 좋지 않은 결점이 있고 별도의 가공장비인 롤로오밍(Roll Forming) 설비가 필요하여 제작단가가 많이 소요되며, 보강밴드가 필요 이상으로 음극선관에 힘을 가하여 응력감소에 역효과를 발생시키는 등의 결점이 있다.In addition, overlapping reinforcement band (1b) is easy to occur overlapping boom between the overlap (in this case), in this case, the heat transfer difference occurs when the reinforcing band is heated, the reinforcing band is bent inward, which is not good workability when tightening the reinforcing band It requires a separate processing equipment, Roll Forming equipment, which requires a lot of manufacturing cost, and a reinforcing band is required to apply negative force to the cathode ray tube, causing adverse effects on stress reduction.

본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 음극선관의 보강효과를 최대로 하기 위해 체결되는 보강밴드의 단면두께를 고진공시 발생되는 응력선도의 크기에 비례하도록 형성하여 진공시 발생되는 음극선관의 응력을 확실하게 감소화할 수 있고, 외부 충격시 음극선관의 폭축을 방지할 수 있을 뿐만 아니라, 필요 이상 보강밴드를 두껍게 하지 않아도 되는 음극선관의 보강밴드를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, to maximize the reinforcing effect of the cathode ray tube, to form a cross-sectional thickness of the reinforcing band fastened in proportion to the magnitude of the stress diagram generated during high vacuum to produce a cathode ray tube It is an object of the present invention to provide a reinforcing band of a cathode ray tube that can reliably reduce the stress of the anode, prevent the cathode ray tube from being constricted during an external impact, and not have to thicken the reinforcing band more than necessary.

상기한 목적을 달성하기 위해 본 고안은 보강밴드의 단면두께가 판넬페이스에서 몰드매치선까지는 점차 두께가 증가되고, 몰드매치선에서 펀넬쪽으로는 점차 두께가 감소되도록 형성된 음극선관의 보강밴드이다.In order to achieve the above object, the present invention is a reinforcement band of a cathode ray tube formed so that the cross-sectional thickness of the reinforcement band is gradually increased from the panel face to the mold match line, and gradually decreases from the mold match line to the funnel.

이하, 본 고안의 일실시예를 첨부도면 제4도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 4.

제4도는 본 고안의 보강밴드가 음극선관에 체결된 상태를 나타낸 종간면도로서, 음극선관에 체결되는 보강밴드(1)의 단면두께가 판넬(3)의 페이스(Face)에서 판넬(2)의 바텀부와 스크트부의 이음부인 몰드매치선까지는 점차 두께가 증가되고, 몰드매치선에서 펀넬(3)쪽으로는 점차 두께가 감소되도록 하는데, 보강밴드의 두께는 음극선관의 고진공시 판넬(2)의 스커트부에서 발생되는 응력의 크기에 비례하도록 형성되어 구성된다.Figure 4 is a longitudinal cross-sectional view showing a state in which the reinforcing band of the present invention is fastened to the cathode ray tube, the cross-sectional thickness of the reinforcement band (1) fastened to the cathode ray tube of the panel (2) at the face (Face) of the panel (3) The thickness is gradually increased from the mold matching line, which is a joint part of the bottom part and the scutting part, and the thickness is gradually decreased from the mold matching line toward the funnel 3, and the thickness of the reinforcing band is high in the panel 2 during the high vacuum of the cathode ray tube. It is formed to be proportional to the magnitude of the stress generated in the skirt portion.

이와 같이 구성된 본 고안은 제4도에 나타낸 바와 같이, 음극선관에 체결되는 보강밴드(1)의 단면두께가 판넬(2)의 페이스에서 판넬(2)의 바텀부와 스커트부의 이음부인 몰드매치선까지는 점차 두께가 증가되고, 몰드매치선에서 펀넬(2)쪽으로는 점차 두께가 감소되어 몰드매치선에서 보강밴드(1)의 두께가 최대로 되도록 형성되므로써, 보강밴드(1)의 두께가 음극선관의 고진공시 판넬(2)의 스커트부에서 발생되는 인장 및 압축응력의 크기에 비례하여 대응할 수 있게된다.According to the present invention configured as shown in FIG. 4, the cross section thickness of the reinforcing band 1 fastened to the cathode ray tube is a mold-matching line which is a joint part of the bottom part of the panel 2 and the skirt part at the face of the panel 2. The thickness of the reinforcing band 1 is increased by gradually increasing the thickness until the thickness of the reinforcing band 1 is maximized in the mold matching line by gradually decreasing the thickness from the mold matching line toward the funnel 2. In proportion to the magnitude of the tensile and compressive stress generated in the skirt portion of the panel (2) during high vacuum.

따라서, 고진공시 발생되는 음극선관의 응력을 확실하게 감소시켜 최소화 할 수 있으며, 외부 충격시 음극선관의 폭축을 방지할 수 있고, 보강밴드(1)를 필요이상으로 두껍게 하지 않아도 되므로 인해 제작단가를 절감시킬 수 있게된다.Therefore, the stress of the cathode ray tube generated during high vacuum can be reliably reduced and minimized, and the shrinkage of the cathode ray tube can be prevented during external impact, and the reinforcing band 1 does not have to be thickened more than necessary, thereby increasing the manufacturing cost. Can be saved.

또한, 보강밴드(1)를 인발이나 압축작업으로 간단히 제작할 수 있고 보강밴드(1)의 사이뜸이 발생되지 않아 보강밴드(1)의 가연시 안쪽으로 휘어지는 것을 방지할 수 있게된다.In addition, the reinforcing band (1) can be easily produced by drawing or compressing operation, and it is possible to prevent the bending of the reinforcing band (1) inward when the reinforcing band (1) is twisted.

이상에서와 같이, 본 고안은 음극선관의 고진공시 발생된 응력을 감소시키기 위하여 판넬(2)의 스커트부에 체결되는 보강밴드(1)의 두께가 응력선도의 크기에 비례하도록 형성되므로써, 진공시 발생된 음극선관의 응력최소화 및 외부충격시 음극선광의 폭축을 방지할 수 있고, 보강밴드(1)의 제작단가를 절감시킬 수 있는 매우 유용한 고안이다.As described above, the present invention is formed in such a way that the thickness of the reinforcing band 1 fastened to the skirt portion of the panel 2 is proportional to the magnitude of the stress diagram in order to reduce the stress generated during the high vacuum of the cathode ray tube.
