본 고안은 브라운관용 전면유리에 관한 것이다.The present invention relates to a windshield for a CRT.
브라운관의 내부는 10 Torr 정도의 진공도를 갖는다.The inside of the CRT has a vacuum degree of about 10 Torr.
이렇게 브라운관의 내부가 진공으로 형성되는 결과로서, 브라운관의 내부가 진공으로 형성되는 결과로서, 브라운관의 외곽체는 대기압에 의한 압축력과 인장력을 받게 되며, 외부충격 및 열충격에 폭발할 위험성을 포함하게 된다.As a result, the inside of the CRT is formed in a vacuum, and the inside of the CRT is formed in a vacuum, and the outer shell of the CRT is subjected to compressive and tensile forces by atmospheric pressure, and includes a risk of explosion in external shock and thermal shock. .
종래부터 브라운관의 폭발에 대비한 수단으로서 여러방식이 적용되고 있다.Conventionally, various methods have been applied as a means for the explosion of CRT.
예를 들면 폭발시 안전대책의 일환으로 전면유리를 후방의 퍼늘측 보다 강도높은 유리재로 형성하여 폭발이 생긴다면 퍼늘측이 우선적으로 파열되도록 한다거나, 전면유리와 퍼늘 이음새 부위에 방폭밴드를 감아 붙여서 기계적강도를 향상시키는 등을 거론할 수 있다.For example, as part of the safety measures in case of explosion, the front glass is formed of a glass material of higher strength than the rear side of the perimeter, so that if the explosion occurs, the perimeter side will be ruptured first, or the explosion-proof band is wrapped around the front glass and the perimeter seam. Improve the mechanical strength, and the like.
그리고 브라운관의 전면유리에 있어서는 장,단변의 가장자리 부분이 가장 큰 인장력을 받는 부분으로 되기 때문에, 이 부분의 두께를 여타부분보다 두껍게 형성함이 통상이다.In the windshield of the CRT, since the edges of the long and short sides become the part receiving the greatest tensile force, it is common to form the thickness of this part thicker than the other parts.
좀 더 상세히 설명하면 제 1 도의 도시와 같이 가장자리 두께(T1)을 화면측 두께(T2)보다 훨씬 두껍게 하여 인장력에 충분히 견딜수 있게 하고 있다.In more detail, as shown in FIG. 1, the edge thickness T1 is made much thicker than the screen side thickness T2 to sufficiently endure the tensile force.
이와같이 가장자리 두께(T1)을 화면측 두께(T2)보다 두껍게 형성하면 안정성을 유지할 수 있으나, 이에 따른 재료의 손실로 생산원가가 상승하게 되고, 특히나 브라운관의 전체중량을 고려하여 볼때 가장자리 두께(T1)의 증가는 한계가 있다.As such, when the edge thickness T1 is formed thicker than the screen side thickness T2, stability can be maintained, but the production cost increases due to the loss of material. In particular, the edge thickness T1 is considered in consideration of the total weight of the CRT. The increase is limited.
본 고안은 전기한 종래 브라운관이 갖는 제반문제점을 해소하고자 안출한 것으로서, 재료비를 절감하고, 구조적으로 안정성을 갖는 브라운관용 전면유리를 제공함에 그 목적이 있다.The present invention has been made in order to solve the problems of the conventional CRT, the purpose is to reduce the material cost, and to provide a CRT front glass having a structural stability.
이의 실현을 위하여 본 고안은 브라운관 전면유리의 장,단변 가장자리부에 방사선 방향 또는 장,단변에 임의 각도를 주어 보강돌기를 다수개 설치하여 구성됨을 특징으로 한다.In order to realize this, the present invention is characterized in that a plurality of reinforcing projections are provided by giving an arbitrary angle to the radiation direction or the long side and the short side of the CRT front glass.
이하 본 고안을 첨부된 도면에 의거하여 실시예에 따라 설명하면 다음과 같다.Hereinafter, the present invention will be described according to embodiments based on the accompanying drawings.
제 2 도에 도시한 바와 같이, 브라운관용 전면유리(1)은 통상적으로 가로방향으로 장변(1a)가 형성되고, 세로방향으로 단변(1b)가 형성되어 전체적으로 보아 장방형을 이루고 있다.As shown in Fig. 2, the windshield 1 for the tube is usually formed with a long side 1a in the transverse direction and a short side 1b in the longitudinal direction to form a rectangular shape as a whole.
장변(1a)와 단변(1b)는 일정곡률을 갖는 화면부(2)의 융착되어 일체로 되어 있다.The long side 1a and the short side 1b are integrally fused together with the screen portion 2 having a constant curvature.
장,단변(1a),(1b)와 화면부(2)의 융착부(3)은 라운딩되어 재료역학적으로 안정을 유지토록 되어 있다.The long and short sides 1a and 1b and the fusion portion 3 of the screen portion 2 are rounded to keep the material mechanically stable.
본 고안은 장, 단변(1a),(1b)와 화면부(2)의 내측에 다수의 보강돌기(4)를 일체로 형성하여 고진공 상태에서 발생되는 인장력을 감쇠시키도록 되어 있다.The present invention is designed to attenuate the tensile force generated in the high vacuum state by integrally forming a plurality of reinforcing projections 4 inside the long, short sides (1a), (1b) and the screen portion (2).
그리고, 브라운관용 전면유리(1)은 보강돌기(4)가 인장력을 많이 받는 장,단변(1a),(1b)에 적당한 간격으로 다수개 설치되어져 있어 융착부(3)이 얇은 부분과 두꺼운 부분으로 교차됨으로서 고진공하에서 인장력을 감쇠시킬 수 있게 된다. 이상과 같이 본 고안은 구조적 또는 재료 역학적으로 고전공에 대한 인장력을 감쇠시킬 수 있어, 종래 브라운관용 전면유리가 갖는 문제점을 해소시킬 수 있는 고안인 것이다.In addition, the front glass 1 for the CRT is provided with a plurality of reinforcing protrusions 4 at the appropriate intervals on the long side, short sides 1a, and 1b, which receive a lot of tensile force, so that the fusion portion 3 is thin and thick. By intersecting with, it is possible to damp the tensile force under high vacuum. As described above, the present invention is a device capable of attenuating the tensile force to the high hole structurally or material dynamics, and can solve the problems of the conventional CRT windshield.
