본 고안의 전자총의 히이터 지지 구조체에 관한 것으로서, 특히 용이한 조립성으로 높은 정밀도를 갖도로 개량된 전자총의 히이터 지지구조체에 관한 것이다.The present invention relates to a heater support structure of an electron gun, and more particularly, to a heater support structure of an electron gun improved to have high precision with easy assembly.
일반적인 전자총의 히이터 지지구조체는 제1도에 도시된 바와 같이 히이터(20)를 지지고정하는 두개의 접속편(30)(30)과, 이 접속편(30)을 비이드 글래스(50)에 대해 위치고정시키는 고정편(40)(40)으로 구성되는데, 상기의 양 접속편(30)(30)은 중간의 브리지(B)를 통해 한몸을 이루고 있다가, 히이터(20)의 조립공정이 완료된 후에 브리지(B)가 제거됨으로써 별개 몸체로 분리되는 것이다.The heater support structure of a typical electron gun has two connecting pieces 30 and 30 for holding and fixing the heater 20 as shown in FIG. 1, and the connecting piece 30 is positioned with respect to the bead glass 50. It consists of fixing pieces (40, 40) to be fixed, wherein both connecting pieces (30, 30) form a body through the bridge (B) in the middle, after the assembly process of the heater 20 is completed By removing the bridge (B) is to separate into a separate body.
이와같은 접속편(30)(30)은 상기 히이터(20)을 단자(21)(21)로 전력을 인가하는 전달체로서의 역할뿐만아니라 상기 히이터(20)를 슬리이브(60)에 대한 상대적인 위치를 결정하는 역할을 하는 것으로서, 비교적 그 크기가 작기 때문에 고정편(40)에 대해 용접하기가 번거롭다.Such connection pieces 30 and 30 not only serve as a carrier for applying power to the heater 20 to the terminals 21 and 21, but also position the heater 20 relative to the sleeve 60. As a deciding role, welding to the stationary piece 40 is cumbersome because of its relatively small size.
이와 같은 구조의 히이터 지지 구조체는 부품간 즉, 히이터(20), 접속편(30), 고정편(40)간의 상대위치를 결정하여 주는 구조적 수단을 갖추고 있지 않기 때문에 조립 작업이 까다롭고 부품조립 정밀도의 산포도가 크기 때문에 제품간의 특성차를 크게 하는 단점이 있다.The heater support structure having such a structure is difficult to assemble and has a precision in assembling precision because it does not have a structural means for determining the relative position between parts, that is, the heater 20, the connecting piece 30, and the fixing piece 40. Due to the large scatter of, there is a disadvantage in that the characteristic difference between products is increased.
본 고안은 상기한 문제점을 해결하기 위한 것으로서, 용이한 조립성으로 높은 조립정밀도와 낮은 산포도를 갖는 전자총의 히이터 지지 구조체를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a heater support structure for an electron gun having high assembly precision and low scattering degree with easy assembly.
상기의 목적을 달성하기 위하여 본 고안은, 히이터 단자에 접속되는 접속편과, 이 접속편을 비이드 글래스에 대해 위치고정시키는 고정편을 갖춘 전자총의 히이터 지지구조체에 있어서, 상기 접속편에 상기 히이터 단자의 선단부와 상기 고정편의 상부축 가장자리가 접촉 구속되는 단차부를 형성하여서 상기 접속편에 대한 상기 히이터 단자와 상기 고정편 가능이 상대적 위치가 안내될 수 있도록 구성한 점에 그 특징이 있다.In order to achieve the above object, the present invention provides a heater supporting structure for an electron gun having a connecting piece connected to a heater terminal and a fixing piece for positioning the connecting piece with respect to a bead glass, wherein the heater is attached to the connecting piece. It is characterized in that the heater terminal and the fixing piece possible relative to the connecting piece are formed so as to form a stepped portion in which the front end portion of the terminal and the upper shaft edge of the fixing piece are contact-constrained.
이하 첨부된 도면을 참조하면서 본 고안의 한실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도에 본 고안의 한 실시예가 발췌도시되어 있다.2, an embodiment of the present invention is shown.
이는 종래의 구조와 마찬가지로 히이터(20)의 단자(21)(21)가 용접고정되는 접속편(30)(30)과, 이를 지지고정한채 비이드 글래스(50)에 고착되는 고정편(40)으로 구성되며, 상기 접속편(30)(30)에 본 고안의 특징적인 요소로서 Z형 단차부(31)(31)가 형성된다. 이 단차부(31)(31)는 고정편(40)의 상부측 가장자리와 나란한 방향으로 주름진 형태로 절곡형성된다.This is the same as the conventional structure, the connecting piece 30, 30 to which the terminals 21 and 21 of the heater 20 are welded and fixed, and the fixing piece 40 fixed to the bead glass 50 while holding it fixed. Consists of, Z-shaped step portion 31, 31 is formed as a characteristic element of the present invention on the connecting piece (30, 30). The stepped portions 31 and 31 are bent in a corrugated form in a direction parallel to the upper edge of the fixing piece 40.
이와같은 구성을 갖는 본 고안의 히이터 지지구조체는 제2도 및 제3도에 도시된 바와 같이 히이터(20)의 단자(21)와 고정편(40)의 상부측 가장자리가 상기 접속편(30)의 Z형 단차부(31)에 접촉 구속됨으로써 상호간의 상대위치가 결정될 수 있도록 구성되어 있다. 즉 히이터(20)는 그 하부의 단자(21)의 선단부가 단차부(31)의 상면에 접촉됨으로서 접속편(30)에 대한 단자(21)의 중첩길이가 제한되고, 이와 마찬가지로 상기 고정편(40)도 상기 단차부(31)의 저면에 접촉됨으로써 그 중첩폭이 제한된다. 결과적으로 상기 세 부품간의 상대적 위치가 단차부(31)에 의해서 결정되게 되는바, 부품간의 용접작업이 매우 손쉬워 지고, 제품간의 조립정밀도의 산포가 크게 저감된다.The heater supporting structure of the present invention having such a configuration has a terminal 21 and a top edge of the fixing piece 40 of the heater 20 as shown in FIGS. 2 and 3. By contact restraint to the Z-shaped stepped portion 31 of the structure is configured to be determined relative to each other. In other words, the heater 20 has a tip end portion of the lower terminal 21 in contact with the upper surface of the stepped portion 31 so that the overlapping length of the terminal 21 with respect to the connecting piece 30 is limited, and the fixing piece ( 40 is also in contact with the bottom of the step portion 31, the overlap width thereof is limited. As a result, the relative position between the three parts is determined by the step portion 31, so that the welding work between the parts becomes very easy, and the distribution of the assembly precision between the products is greatly reduced.
이상에서와 같이 본 고안의 히이터 지지구조체는 구조적으로 부품상호간의 용접위치가 자연히 결정될 수 있도록 구성되어 있다. 따라서 제조가공이 수월하게됨은 물론 제품간의 상호 저감을 통하여 제품간의 품질관리를 매우 용이하게 하여 줄 수 있는 장점을 가진다.As described above, the heater support structure of the present invention is structurally configured such that the welding position between the parts may be naturally determined. Therefore, the manufacturing process is easy, and there is an advantage that can facilitate the quality control between products through mutual reduction between products.
