본 고안은 음극선관용 전자총의 음극구조체에 관한 것으로서 더 상세하게는 홀더를 지지하는 홀더지지편의 개량에 관한 것이다.The present invention relates to a cathode structure of an electron gun for a cathode ray tube, and more particularly, to an improvement of a holder support piece for supporting a holder.
일반적으로 음극선관용 전자총의 음극구조체는, 제1도에 도시된 바와 같이 전자방사물질(6)이 도포된 베이스메탈(5)과, 이 베이스메탈(5)이 그 선단에 지지되며 그 내부에는 히이터(H)가 내장되는 슬리이브(3)와, 이 슬리이브(3)를 이의 하부측으로 부터 지지고정하는 슬리이브 지지체(4)와, 이 슬리이브지지체(4)를 지지함과 아울러 상기 슬리이브(3)를 에워싸도록 된 홀더(2)와, 이 홀더(2)를 지지하며 그 양끝단이 비이드글래스(B)에 융착고정되는 홀더지지편(1)들로 구성된다.In general, a cathode structure of an electron gun for cathode ray tubes includes a base metal 5 coated with an electron-emitting material 6, as shown in FIG. 1, and the base metal 5 is supported at a tip thereof and has a heater therein. A sleeve 3 in which (H) is embedded, a sleeve support 4 for holding and fixing the sleeve 3 from the lower side thereof, and the sleeve support 4 are supported, and the sleeve ( The holder 2 is enclosed by 3), and the holder support piece 1 which supports this holder 2 and whose both ends are fusion-fixed to the bead glass B is comprised.
이와 같이 구성된 종래 음극구조체에 있어서는, 홀더(2)를 홀더지지편(1)에 용접시키기 위하여 상기 홀더지지편(1) 또는 홀더(2)에 일정형태의 용접부위를 인위적으로 형성시켜 용접작업이 수월하게 수행될 수 있도록 하고 있으나 홀더(2)에 대한 홀더지지편(1)의 용접위치결정이 임의적으로 결정되어 짐으로 인해 그 간격(ℓ)의 변화가 제품별로 이루어지게 되고 이로 인해 제품간의 산포가 확대되게 되고, 개별적으로는 캐소오드구조체 전체의 위치불량이 야기되게 된다. 즉, 홀더(2)를 홀러지지편(1)에 용접시킴에 있어서, 홀더(2)와 홀더지지편 캐소오드구조체(1)의 간격(ℓ)은 항상 일정하게 유지되어야 하는 것이나, 용접시 용접산포로 인해 간격(ℓ)에 변화가 생기고 이로 인하여는 캐소오드구조체 전체의 위치불량이 유발되게 되며, 특히 홀더(2)의 중심과 홀더(2)상부에 조립되는 제1전극(7)의 빔통과공 중심과를 일치시키시 어려워서 전자빔발생 특성인 에미션 성능 및 화이트밸런스 특성의 열화를 억제할 수 없었다.In the conventional negative electrode structure configured as described above, in order to weld the holder 2 to the holder support piece 1, a welding operation of a certain form is artificially formed on the holder support piece 1 or the holder 2 so that a welding operation is performed. The welding position of the holder support piece 1 with respect to the holder 2 is arbitrarily determined, but the change of the gap ℓ is made for each product, resulting in the spread between products. Is enlarged, and individually causes mislocation of the entire cathode structure. That is, in welding the holder 2 to the hollow support piece 1, the distance l between the holder 2 and the holder support piece cathode structure 1 should be kept constant at all times, but welding at the time of welding. Dispersion causes a change in the spacing (l), which causes mislocation of the entire cathode structure, in particular the beam of the first electrode 7 assembled to the center of the holder 2 and above the holder 2. It was difficult to coincide with the center of the through-hole so that degradation of emission performance and white balance characteristics, which are electron beam generation characteristics, could not be suppressed.
이에 대한 해결방으로 홀더(2)와 홀더지지편(1)을 일정위치에 서로 용접하기 위해서는 별도의 조립용 치구가 필요하게 되는데, 이와 같은 경우 이에 따른 부품이 증가되고 또한 조립공정이 증가하게 되어 제품의 원가상승이 유발되게 된다.In order to solve this problem, in order to weld the holder 2 and the holder support piece 1 to each other at a predetermined position, a separate assembly jig is required. In this case, the parts are increased accordingly and the assembly process is increased. Product cost will increase.
본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서, 홀더에 대한 홀더지지체의 상대위치 즉, 용접위치의 결정이 용이하도록 그 구조가 개선된 음극선관용 전자총의 음극구조체를 제공함에 그 목적이 있다.The present invention has been made in view of the above problems, and an object of the present invention is to provide a cathode structure of an electron gun for a cathode ray tube whose structure is improved to facilitate determination of a relative position of the holder support, that is, a welding position, with respect to the holder.
상기 목적을 달성하기 위하여 본 고안은, 전자방사물질이 도포되는 베이스메탈과, 이를 그 상단에 지지하며 그 내부에는 히이터가 내장되는 슬리이브와 상기 슬리이브를 지지하는 슬리이브지지체와, 상기 슬리이브지지체를 고정함과 아울러 상기 슬리이브를 에워싸는 홀더와, 상기 홀더를 비이드글래스에 고정하는 홀더지지편을 구비하는 음극선관용 전자총의 음극구조체에 있어서, 상기 홀더의 상단부에 마련되는 플랜지부에 접촉되는 거리제한용 연장부를 상기 홀더지지편의 몸체중간에 형성하여서, 상기 연장부에 의해 상기 홀더에 대한 지지체의 용접위치가 결정되도록 한 점에 그 특징이 있다. 이하 도면을 참조하여 본 고안 음극선관용 전자총의 음극구조체의 바람직한 실시예를 상세히 설명한다.In order to achieve the above object, the present invention provides a base metal to which an electron-emitting material is applied, and a sleeve supporting the sleeve and a sleeve having a heater therein, and a sleeve supporting the sleeve. A cathode structure of an electron gun for a cathode ray tube having a holder for holding a support and a holder surrounding the sleeve, and a holder support piece for fixing the holder to a bead glass, the contact of which is provided with a flange provided at an upper end of the holder. The distance-limiting extension is formed in the middle of the body of the holder support piece so that the welding position of the support body to the holder is determined by the extension part. Hereinafter, a preferred embodiment of a cathode structure of an electron gun for a cathode ray tube of the present invention will be described in detail with reference to the accompanying drawings.
제2a, 2b도에 도시된 바와 같이 본 고안 음극선관용 전자총의 음극구조체는, 전자방사물질(60)이 도포된 베이스메탈(50)과, 이 베이스메탈(50)이 그 선단에 지지되며 히이터(H)가 내장되는 슬리이브(30)와, 이 슬리이브(30)를 지지하는 슬리이브지지체(40)와 이 슬리이브지지체(40)를 지지하며, 그 상단부에 플랜지부(20a)가 일체로 형성된 홀더(20)와, 이 홀더(20)를 지지하며 그 양끝단이 비이드글래스(B)에 융착고정되는 홀더지지편(10)을 구비하여 구성된다.As shown in FIGS. 2A and 2B, the cathode structure of the electron gun for the cathode ray tube of the present invention includes a base metal 50 to which an electron radiating material 60 is coated, and the base metal 50 is supported at the tip thereof, and a heater ( A sleeve 30 having a built-in H), a sleeve support 40 supporting the sleeve 30, and the sleeve support 40 are supported, and a flange portion 20a is integrally formed at the upper end thereof. The holder 20 is formed, and the holder 20 is supported by the holder 20 and both ends thereof are fused and fixed to the bead glass B.
상기 홀더지지편(10)의 중간부위에는 홀더지지체(10)의 센터를 중심으로 대칭인 연장부(10a)가 일체로 형성되며 상기 연장부(10a)는 홀더(20)의 플랜지부(20a) 선단에 완전 밀착된다.An intermediate portion of the holder support piece 10 is integrally formed with an symmetrical extension 10a around the center of the holder support 10 and the extension 10a is a flange portion 20a of the holder 20. Fully adhered to the tip.
상기와 같이 구성된 본 고안에 따른 음극선관용 전자총의 음극구조체는, 홀더(20)와 홀더지지편(10)을 용접고정함에 있어 홀더(20)의 플랜지부(20a) 선단에 홀더지지편(10)의 연장부(10a)가 접촉되게 됨으로써 상대적 용접위치가 자연히 결정되게 됨으로써 구조체 전체의 조립정밀도가 향상되게 된다.The cathode structure of the electron gun for the cathode ray tube according to the present invention configured as described above, the holder support piece 10 at the tip of the flange portion 20a of the holder 20 in the welding fixing of the holder 20 and the holder support piece 10 By contacting the extension portion 10a of the relative weld position is naturally determined, the assembly precision of the entire structure is improved.
종래에는 홀더와 홀더지지편의 용접시, 홀더와 홀더지지편의 사이에 상호 유동을 허용하는 갭이 존재함으로써 용접산포에 따른 간격(ℓ)의 변화가 발생하게 되었으나, 본 고안에서는 홀더지지편(10)에 연장부(10a)가 형성되어 있으므로 이 연장부(10a)가 홀더(20)의 플랜지부(20a)에 접촉되게 되어 홀더와 홀더지지편간의 상대용접위치를 손쉽게 결정할 수 있게 된다.Conventionally, when welding the holder and the holder support piece, there is a gap that allows mutual flow between the holder and the holder support piece, so that a change in the spacing (l) occurs due to welding dispersion, but in the present invention, the holder support piece 10 Since the extension part 10a is formed in the extension part 10a, the extension part 10a comes into contact with the flange part 20a of the holder 20, so that the relative welding position between the holder and the holder support piece can be easily determined.
이러한 본 고안에 의해서 홀더(20)의 중심과 제1전극(70)의 빔통과공 중심을 정확하게 일치시킬 수 있게 되는 바, 전자빔발생 특성인 에미션 성능 및 화이트밸런스 특성이 열화되는 것을 방지할 수 있다. 더 나아가서는 홀더(20)와 홀더지지편(10)의 용접위치를 잡아주기 위한 치구가 필요없는 것이어서 부품수의 감소에 의한 원가절감을 도모할 수 있다.According to the present invention, the center of the holder 20 and the center of the beam through hole of the first electrode 70 can be exactly matched, and the degradation of emission performance and white balance characteristics, which are electron beam generation characteristics, can be prevented. have. Furthermore, since the jig for holding the welding position of the holder 20 and the holder support piece 10 is not necessary, the cost can be reduced by reducing the number of parts.
