본 고안은 형광 표시관의 음극 지지장치에 관한 것으로 특히, 음긱지지장치의 마운트(mount)와 음극지지대를 프릿(frit)으로 고착되게 하여 음극 필라멘트의 높이를 균일하게 하는 음극지지장치에 관한 것이다.The present invention relates to a negative electrode support device of a fluorescent display tube, and more particularly, to a negative electrode support device to uniform the height of the negative electrode filament by fixing the mount (mount) and the negative electrode support of the music holding device with a frit (frit).

일반적으로 형광표시장치는 제1도에서와 같이 유리 또는 세라믹과 같은 절연재로 된 기판(1)위에 디스플레이되는 여러 패턴을 구성하는 각 세그먼트 전극군(2)의 배열에 따라 전기적 접속 배선(3), 연출도선 단자(4)및 세그먼트 전극등의 도전피막과 이것들을 절연하는 절연피막(5)등을 포개어 부쳐서 글래스기판을 형성하고, 각 세그먼트 전극에는 형광체(6)를 입혀서 양극의 패턴표시부를 형성하며, 각 세그먼트 전극군(2)과 대향하여 여러개의 그리드(8)의 열전자를 방출하는 음극 필라멘트(8)를 접속배선(3)에다 도전성 접착제로 접속시켜 글래스기판에 고정시키고, 이들 기판상의 전극부분은 글래스기판과 그 위에 형성되는 진공기밀한 보호캡(7)속에 설치하는 구성으로 되어 있다.In general, the fluorescent display device is connected to the electrical connection wiring (3), according to the arrangement of each segment electrode group (2) constituting the various patterns displayed on the substrate (1) made of an insulating material such as glass or ceramic as shown in FIG. A conductive substrate such as the lead wire terminal 4 and the segment electrode and the insulating film 5 that insulates them are stacked to form a glass substrate, and a fluorescent substance 6 is coated on each segment electrode to form a pattern display part of the anode. The negative electrode filament 8, which emits the hot electrons of the multiple grids 8 opposite to each of the segment electrode groups 2, is connected to the connection wiring 3 with a conductive adhesive to be fixed to the glass substrate, and the electrode portions on these substrates Is installed in a glass substrate and a vacuum tight protective cap (7) formed thereon.

상기의 음극 필라멘트(9) 등을 지지하는 형광 표시관의 음극지지장치는 제2도에서와 같이 음극 팔라멘트(9)를 고정 하는 음극지지대(10)와 이와 용접하여 고정하는 마운트(11)로 구성하는 바, 제2도 b와 같이(양쪽부분)이 절결된 모양의 고착부를 갖는 마운트(11)와 음극지지대(10)를 용접하여 부착시킨 다음 고착부에 프릿을 용착(빗금친 분이 용착되는 부분임)되게 하여 글래스 기판상에 마운트를 고정시키는 것이다.The cathode support device of the fluorescent display tube supporting the cathode filament 9 and the like is a cathode support 10 for fixing the cathode filament 9 and a mount 11 for welding by fixing the cathode filament 9 as shown in FIG. As shown in FIG. 2, the mount 11 and the cathode support 10 having the fixing portion having the cut out shape as shown in FIG. 2 (b) are welded and attached, and then the frit is welded to the fixing portion. Part) to secure the mount on the glass substrate.

이와 같이 양단만이 절결된 형태의 마운트(11)를 사용하여 프릿의 소성후 음극 필라멘트(9)를 고정시키는 경우에는 제2도 a와 같이 플릿 소정장치의 부정확 동작 및 필라멘트이 장력등의 원인으로 음극지지대(10)와 용접된 마운드(11)가 더불어 휘어지게 되는데, 즉 음극지지장치와 글래스 기판상과의 들뜸 현상이 발생되기 때문에 전체적으로 음극 필라메트의 높이가 불균일하게 되어 형광표시관의 휘도자가 발생될 뿐만 아니라 이에 따라 제작공정의 불량율이 높아지는 문제점이 있었다.As described above, in the case where the cathode filament 9 is fixed after the frit is fired by using the mount 11 having a cut-out shape at both ends, as shown in FIG. The support 10 and the welded mound 11 are bent together, i.e., since the lifting phenomenon between the cathode support device and the glass substrate is generated, the height of the cathode filament becomes non-uniform and the luminance of the fluorescent display tube is generated. Not only this, there was a problem that the defect rate of the manufacturing process is increased accordingly.

또한, 본 고안자에 의해 선출원된 음극지지장치에 개재된 기술(실용 제89-4085)은 음극지지대와 마운트를 부착하여 글래스기판상에 고정되게 하므로써 음극 필라멘트등을 견고하게 고정시키는 구조로 되어 있는 것이다.In addition, the technology (practical 89-4085) interposed in the negative electrode support device pre- filed by the present inventors has a structure to firmly fix the negative electrode filament by attaching the negative electrode support and the mount to be fixed on the glass substrate. .

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로 형광표시관의 음극지지장치의 음극지지대가 양단의 고착부 이외에도 적어도 하나 이상의 프릿 용착부를 형성 하도록 하여 마운트 없이 직접 그래스기판상에 고착되게 함으로써 음극지지장치의 구조를 간단히 하여 제작공정수 및 비용을 낮추기 위한 음극지지장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, so that the cathode support of the cathode support device of the fluorescent display tube is formed on at least one frit welding part in addition to the fixing parts at both ends thereof, so that the cathode support is directly attached to the glass substrate without a mount. It is an object of the present invention to provide a cathode support device for reducing the manufacturing process number and cost by simplifying the structure of the cathode support device.

상기와 같은 목적을 달성하기 위한 본 고안은, 양단이 절결된 고착부와, 이 고착부 내부쪽으로 직사각형으로 관통된 3개의 홀이 이웃하여 다수개 형성되어 있으면서 용해된 유리성분의 프릿으로 소성하여 음극지지대와 글래스기판을 견고하게 고착하도록된 프릿용착부로 구성되어, 상기 프릿용착부의 관통홈을 통하여 프릿으로 상기 글래스기판에 용착되게 되어 이에 따라 장력에 따른 휘어짐 현상이 제거됨으로 음극필라멘트의 높이를 균일하게 유지할 수 있어 고른 열전자를 방출하게 된다.The present invention for achieving the above object is a cathode by firing with a frit of a glass component dissolved while having a plurality of cutouts in which both ends are cut, and three holes penetrated in a rectangle toward the inside of the fixing part are formed adjacent to each other. Consists of a frit welding portion to firmly adhere the support and the glass substrate, the glass plate is welded to the glass substrate by the frit through the through groove of the frit welding portion, thereby eliminating the bending phenomenon due to tension, thereby uniformly increasing the height of the negative electrode filament It can hold and emit evenly hot electrons.

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

본 고안 형광표시관의 음극지지대(20)의 구조는 제3도에 도시된 바와 같이 음극지지대(20) 양끝에 형성되어 있는 양단이 절결된 고착부(21A, 21B)와 이 고착부(21A, 21B) 내부쪽으로 직사각형으로 관통된 3개의 홀이 인접된 배열로 형성되어 있으면서 용해된 유리성분의 프릿으로 소성하여 상기의 음극지지대(20)와 글래스기판은 견고하게 고착하도록된 프릿용착부(22A~22D)로 구성되어 있다.As shown in FIG. 3, the structure of the cathode support 20 of the present invention fluorescent display tube includes fixing portions 21A and 21B having both ends formed at both ends of the cathode support 20 and the fixing portions 21A, 21B) The frit welding portion 22A to which the cathode support 20 and the glass substrate are firmly adhered by firing with the melted glass frit while forming three adjacent holes penetrated into the rectangle in an adjacent arrangement. 22D).

상기와 같은 구성으로된 본 고안의 작용효과를 설명한다.It describes the operation and effect of the subject innovation of the above configuration.

본 고안 형광표시관의 음극지지장치는 제4도에 도시된 바와 같이 상기 프릿용착부(22A~22D0의 관통홀을 통하여 프릿으로 용착되게 한 다음 프릿소성장치(도시안됨)에 넣어 소성시킨다. 따라서 상기 프릿용착부(22A~22D)의 관통홀을 통하여 상기 글래스기판에 용착된 프릿이 굳어짐으로 상기 글래스기판과 상기 음극지지대(20)가 견고하게 고착되어 장력에 따른 휘어짐 현상이 제거되므로 음극필라멘트의 높이를 균일하게 유지할 수 있어 음극필라멘트에서 고른 열전자를 방출하게 된다.The cathode support device of the fluorescent display tube of the present invention is welded to the frit through the through holes of the frit welding portions 22A to 22D0 as shown in FIG. 4, and then put into a frit firing apparatus (not shown) and fired. The frit welded to the glass substrate is hardened through the through holes of the frit welding portions 22A to 22D, so that the glass substrate and the negative electrode support 20 are firmly adhered to each other so that the bending phenomenon due to the tension is removed. The height can be maintained uniformly, thereby emitting evenly hot electrons from the cathode filament.

따라서, 형광표시관의 디스플레이시 휘도차가 발생되지 않는다.Therefore, no luminance difference occurs during display of the fluorescent display tube.

즉, 형성된 형광 표시관의 음극지지장치는 마운트 없이도 견고하게 음극필라멘트를 지지하는 음극지지대를 글래스기판상에 고착되게 하면, 음극 필라멘트의 높이가 균일하게 된다.That is, the negative electrode support device of the formed fluorescent display tube is made to have a uniform height of the negative electrode filament when the negative electrode support that firmly supports the negative electrode filament without the mount is fixed on the glass substrate.

그리고, 음극지지대(20)의 용착부(22A~22D)는 제3도에 있어서 직사각형의 관통된 홀 3개가 인접된 배열의 구조로 되어 있으나 관통된 형상은 원형등으로 제작할 수도 있고, 또한 관통홀이 다수개로 배열된 구조로 제작하여도 된다.The welding portions 22A to 22D of the cathode support 20 have a structure in which three rectangular through holes are adjacent to each other in FIG. 3, but the through shape may be formed in a circular shape or the like. You may manufacture with the structure arrange | positioned in plurality.

또한 프릿용착부를 음극지지대(20)상에 적어도 하나 이상을 형성시켜도 전술한 효과를 기대할 수 있다.In addition, even if at least one frit welding portion is formed on the negative electrode support 20, the above-described effects can be expected.

한편 음극지지장치와 글라스(galss)및 패턴과의 간격이 협소한 경우 언급한 본 고안의 실시예와는 다른 구조로 효고를 기대할 수 있는데, 이러한 음극지지대는 양단에 위치한 절결된 형태의 고착부를 형성하지 않고 전술한 실시예에 따른 프릿 용착부호로만 형성하는 것이다.On the other hand, when the gap between the negative electrode support device and the glass (galss) and the pattern is narrow, Hyogo can be expected to have a different structure from the above-described embodiment of the present invention. Such a negative electrode support forms a cut-out fixed portion located at both ends. Rather than forming only the frit welding code according to the above embodiment.

이상에서 설명한 바와 같이 본 고안은 음극지지장치의 음극지지대가 글래스기판에 견고하게 조정되게 하므로써, 첫째, 음극필라멘트가 균일한 높이로 배열되어 형광표시관의 디스플레이시 휘도자가 발생되자 않으며, 둘째, 형광표시관의 불량율을 저할시킬 수 있으며, 세째, 마운트 없이 음극지지대만으로 음극필라멘트를 고정되게 하기 때문에 제작 공정수를 줄일 수 있음과 더불어 제작비용이 절감되는 효과를 얻을 수 있다.As described above, the present invention allows the negative electrode support of the negative electrode support device to be firmly adjusted to the glass substrate. First, the negative filaments are arranged at a uniform height so that no luminance is generated when the fluorescent display tube is displayed. The failure rate of the display tube can be reduced, and third, since the cathode filament is fixed only by the cathode support without the mount, the number of manufacturing processes can be reduced and the manufacturing cost can be reduced.
