본 고안은 음극선관용 부품인 스템플레아의 형상 설계에 관련된 것으로, 특히 스템(Stem)과 넥크(Neck)의 융착불량과 봉지부 형상불량에 의한 크랙(Crack)을 줄이는 스템플레아에 관한 것이다.The present invention relates to the shape design of a stem flare, which is a component for cathode ray tubes, and more particularly, to a stem flare that reduces cracks due to poor fusion of stems and necks and poor shape of encapsulation parts.

일반적인 음극선관용 스템은 제1도에 도시되는 바와같이, 전자총의 각 전극부에 전원을 공급하여 주고 전극부 조립체를 고정시켜주는 스템핀(3)과, 이 스템핀(3)을 지지하여주는 스템이브(2)와, 이 스템이브(2)와 일체로 되는 스템플레아(1)를 구비하였다.A typical cathode ray tube stem is a stem pin (3) for supplying power to each electrode portion of the electron gun and fixing the electrode assembly, as shown in FIG. 1, and a stem for supporting the stem pin (3). Eve 2 and the stem flare 1 integrated with this stem 2 were provided.

이러한 일반적인 음극선관용 스템은 제1도에 도시되는 바와같이, 용융된 넥크(4)와 예열된 스템플레아(1)가 가스 버어너의 불꽃세기의 조정에 의해 융착되며, 스템이브(2)는 용융된 넥크유리가 스템플레아(1)의 평탄부를 흘러내릴 경우에도 넥크유리가 접촉되지 않도록 하기 위해 그 직경이 가능하면 작도록 설계된다.In this general cathode ray tube stem, as shown in FIG. 1, the molten neck 4 and the preheated stem flare 1 are fused by adjusting the flame intensity of the gas burner, and the stem eve 2 is The diameter is designed to be as small as possible so that the neck glass does not come into contact even when the molten neck glass flows down the flat portion of the stem flare 1.

종래 음극선관용 스템플레아는 제2도에 도시되는 바와같이, 내주연부의 상부가 스템이브(2)와 일체로 형성되고, 내주연부와 외주연부에 이르는 상단부가 평탄면(1a)으로 되어 넥크(4)와 스템의 융착부로 되도록 구성되었다.In the conventional cathode ray tube stem flare, as shown in FIG. 2, the upper portion of the inner circumferential portion is integrally formed with the stem 2, and the upper end portion extending from the inner circumferential portion to the outer circumferential portion becomes a flat surface 1a so that the neck 4 ) And stem.

이러한 종래 음극선관용 스템플레아는 제2도에 도시되는 바와같이, 음극선관 제조에 봉지공정에서, 평탄면(1a)으로 되는 스템의 용착부가 가스버너에 의해 용융된 넥크(4)에 의해 간접적으로 예열되고, 이 예열된 용착부에 용융된 넥크(4)가 가스 버어너의 불꽃세기의 조정에 의해 융착된다.Such a conventional cathode ray tube stem flare is preheated indirectly by the neck 4 in which the welded portion of the stem, which becomes the flat surface 1a, is melted by a gas burner in the sealing process for manufacturing the cathode ray tube as shown in FIG. The melted neck 4 is fused by adjusting the flame intensity of the gas burner.

그러나, 이러한 종래 음극선관용 스템플레아는, 스템플레아의 예열공정에서 가스 버어너의 불꽂이 넥크를 통한 간접적인 열전달에 의하여 예열되는데, 용착부가 평탄면으로 되어 있기 때문에 열전달을 충분히 받지 못하여, 스템플레아의 예열이 충분치 못할 경우가 발생하고, 이로 인해 넥크유리와의 용착불량에 의한 크랙이 발생되었으며, 넥크유리가 용융되어 스템플레아의 평탄부를 타고 흘러내리면서 스템이브와 접촉되어 날카로운 홈을 형성할 경우, 스템 봉지시 응력이 집중되어 봉지형상 불량으로 인한 크랙이 빈번하게 발생되는 문제점이 있었다.However, such a conventional cathode ray tube stem flare is preheated by indirect heat transfer through the flame burner neck of the gas burner in the preheating process of the stem flare, but since the welded portion is a flat surface, the heat transfer is not sufficient. There is a case where the preheating of the child is insufficient, which causes cracks due to poor deposition with the neck glass, and the neck glass melts and flows down the flat part of the stem flare to form a sharp groove in contact with the stem. In this case, there is a problem in that the stress is concentrated when the stem is encapsulated, so that cracks are frequently generated due to the poor shape of the stem.

본 고안의 목적은 음극선관용 브라운관의 부품인 스템플레아의 형상 설계에 관련된 것으로, 특히 봉지공정에서 스템과 넥크의 용착의 경우 발생되는 용착불량과 봉지부의 형상불량에 의한 스템의 크랙을 줄이는 음극선관용 스템플레아를 제공하는데 있다.The object of the present invention relates to the shape design of the stem flare, which is a part of the cathode ray tube CRT, especially for the cathode ray tube which reduces the crack of the stem caused by the poor welding and the poor shape of the encapsulation in the sealing process. To provide a stem flare.

이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 고안 음극선관용 스템플레아는 제3도에 도시되는 바와같이, 용융된 넥크(40)가 스템이브(20)와 접촉되는 것을 방지하는 접촉방지턱(11)이 내측 상부에 형성되고, 표면적증가로 스템예열에서 흡열력을 증가시키기 위한 흡열돌기(12)가 외측 상부에 형성되어 구성됨을 그 기술적 구성상의 특징으로 한다.As shown in FIG. 3, the stem flare for the cathode ray tube of the present invention has a contact preventing jaw 11 formed at an inner upper portion to prevent the molten neck 40 from coming into contact with the stem 20, and the stem has an increased surface area. The technical configuration is characterized in that the endothermic projections 12 for increasing the endothermic force in the preheating is formed on the outer upper portion.

이러한 본 고안 음극선관용 스템플레아는 제3도에 도시되는 바와같이, 용융된 넥크(40)가 스템플레아(10)와 융착되면서 넥트(40)가 스템이브(20)와 접촉이 될 경우, 접촉되는 부분에서 날카로운 봉지형상이 발생되고, 이에 따라 응력이 집중되어 봉지부에서의 가장 취약한 부분으로 되는데, 이를 방지하기 위해 스템플레아(10)에 형성되는 접촉방지턱(11)이 지나치게 용융된 넥크(40)가 흘러내릴지라도 스템이브(20)와 접촉되지 않도록 작용하여 봉지형상이 양호하게 된다.The stem flare for the cathode ray tube of the present invention, as shown in FIG. 3, when the melted neck 40 is fused with the stem flare 10, the neck 40 is in contact with the stem 20, the contact A sharp encapsulation shape is generated at the portion to be formed, and thus stress is concentrated to become the most vulnerable portion in the encapsulation portion. Even if 40 is flowed down, it acts so as not to contact the stem 20 so that the sealing shape is good.

또한, 음극선관용 브라운관의 봉지공정에서 스템플레아(10)가 흡열된 열량이 부족하여 충분한 예열이되지 않았을 경우, 미융착이 되어 크랙의 원인이 되는데, 스템플레아(10)가 표면적이 증가하도록 형성되는 흡열돌기(12)가 스템플레아(10)의 흡열량이 증가하도록 작용하여, 용융된 넥크(40)와의 융착성이 향상되어 진다.In addition, in the encapsulation process of the cathode ray tube CRT, when the stem flare 10 is insufficient in the amount of heat absorbed due to insufficient heat preheating, it becomes unfused and causes cracks. The endothermic protrusions 12 are formed to act to increase the endothermic amount of the stem flare 10, the adhesion to the melted neck 40 is improved.

이상에서 살펴본 바와같이, 본 고안 음극선관용 스템플레아는, 내주연부에 형성되는 접촉방지턱이 지나치게 용융된 넥크가 흘러내질지라도 스템이브와 접촉되지 않도록 함으로써, 봉지형상이 양호하게 하고, 외주연부에 형성되는 흡열돌기가 스템플레아의 흡열량이 증가하도록 함으로써, 용융된 넥크와의 융착성이 형성되어 크랙으로 인한 불량을 감소시킬 수 있는 유용한 것이다.As described above, the stem flare for the cathode ray tube of the present invention has a satisfactory encapsulation shape by preventing the contact bump formed on the inner circumferential portion from coming into contact with the stem, even if the molten neck flows out. By allowing the endothermic protrusion to increase the endothermic amount of the stem flare, fusion with the melted neck is formed, which is useful for reducing defects due to cracks.
