1 : 평판프레임 1a : 측면직각돌출부1: flat frame 1a: side right angle protrusion
본 고안은 칼라 음극선관의 새도마스크와 그 지지프레임에 의한 새도마스크 조립기체와 관련된 것으로서, 이는 특히 상기 지지프레임의 4변에는 다수의 측면직각 돌출부를 마련하므로서 이러한 새도마스크의 조립시에 그변형을 초래하지 않고 조립의 용이성이 보장되어지도록한 그 칼라 음극선관에 관한 것이다.The present invention relates to a shadow mask assembly body of a color cathode ray tube and a shadow mask assembly by the support frame, in particular, at the time of assembling such shadow mask by providing a plurality of side right angle protrusions on four sides of the support frame. The color cathode ray tube is designed so that the ease of assembly is ensured without causing the deformation.
새도마스크형 칼라 음극선관은 제1도와 같이 형광체가 내면에 도포된 전면패널(21)과, 전자총(22) 삽입의네크부(23), 전면괘널(21)에 연결된 퍼늘부(24)로 되어있고, 상기 전면패녈(21)에 대응하여서는 새도마스크(25)가 이의 지지용 평판 프레임(28)으로 스포트용접되어 스프링(27)으로 전면괘널(21)측의 스터드핀(26)에결합되어지는 형태로 되어 있다.The shadow mask type cathode ray tube includes a front panel 21 in which phosphors are applied to the inner surface, a neck portion 23 of an electron gun 22 insertion, and a perimeter portion 24 connected to the front panel 21 as shown in FIG. In response to the front panel 21, the shadow mask 25 is spot welded to the support flat frame 28 thereof, and the spring 27 is coupled to the stud pin 26 on the front panel 21 side with the spring 27. It is in the form that it becomes.
또, 상기 새도마스크(25)와 평판프레임(28)은 제2도와 같이 V형 체결스프랭(a)의 일측끝단은 평판프레임(28)의 평탄면부(28a)에서 스포트용접으로 조립되고. 이후 이에 새도마스크(25)를 조립한다.In addition, the shadow mask 25 and the flat plate frame 28, as shown in FIG. 2, one end of the V-type fastening sprinkler (a) is assembled by spot welding at the flat surface portion 28a of the flat plate frame 28. After this, the shadow mask 25 is assembled.
또, 상기 새도마스크(25)측 스커트부(25a) 끝단에 ㄱ자형 돌출부(25b)가 있으며, 이를 평판프레임(28)에 역시 스포트 용접하여 그 조립기체가 완성되어진다.In addition, there is an L-shaped protrusion 25b at the end of the skirt portion 25a of the shadow mask 25, which is also spot welded to the flat frame 28 to complete the assembly body.
그러나, 이러한 종래기술에서는 전면괘널(21)과 새도마스크(25)간에 일정한 소정간격을 이격 유지시킨 다음돌출부(25b)를 평판프레임(28)측으로 절곡시키고 이후 이 절곡된 부위에 스포트용접을 시켜야 하는 불편한 공정과, 상기 돌출부(25b)의 절곡시 스커트부(25a)의 돌출부(25b)가 위치한 부위에 변형(29)을 초래하는 일이 많아 이러한 새도마스크 조립기체 제작에 불리한 문제점으로 남아 있었다.However, in this prior art, a predetermined predetermined distance is maintained between the front panel 21 and the shadow mask 25, and then the protrusion 25b is bent toward the flat frame 28 and then spot welded to the bent portion. Inconvenient process, and when bending the protrusion 25b, the deformation (29) is often caused to the site where the protrusion (25b) of the skirt portion 25a is located, so it remained a disadvantage in manufacturing such shadow mask assembly gas. .
또, 상기와 같이 새도마스크(25)의 돌출부(25b) 측에서 일어나는 형태변형(29)은 칼라음극션관 동작시의 미스랜딩을 유발시켜 그 화면의 색순도 저하를 야기하는 문제점으로도 대두되었다.In addition, as described above, the shape deformation 29 occurring at the side of the projection 25b of the shadow mask 25 has also been a problem that causes mis-landing during the operation of the color cathode tube, causing the color purity of the screen to decrease.
본 고안의 목적은 상기와 같은 종래기술의 문제점을 개선하고자 안출한 것이다.An object of the present invention is to improve the problems of the prior art as described above.
본 고안은 특히 섀도마스크와 스포트용접으로 이어지는 평판프레임은 이의 소정부위 4변에서 측면직각 돌출부 구성을 가져 상기 새도마스크와 스포트 용접되어지는 평판프레임을 가진 칼라 음극선관을 그 특징으로 하는것이다.The present invention is characterized by a color cathode ray tube having a flat frame which is connected to the shadow mask and the spot welding, and has a flat rectangular frame at the four sides of the predetermined area and has a side right projection.
이하에서 이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail below.
즉, 제3도는 본 고안에 의한 평판프레임(1)과 새도마스크(25)와의 결합상태를 나타내었다.That is, FIG. 3 shows the coupling state between the flat frame 1 and the shadow mask 25 according to the present invention.
여기서는 제4도와 같이 평판프레임(1)의 4변 소정부위에서 하향 절곡된 측면직각 돌출부(1a)가 다수개 형성되어진 구성으로 되어 있다.Here, as shown in FIG. 4, a plurality of side right angle protrusions 1a bent downward from four predetermined portions of the flat plate frame 1 are formed.
또, 상기 측면직각돌출부(1a)는 그 폭이 20∼30mm 정도로 되고 새도마스크(25)의 외측벽 상단에서 바깥쪽으로 접면되는 위치에 마련되어진 것이다.Further, the side right angle protrusions 1a are provided at positions that are about 20 to 30 mm in width and fold outward from the upper end of the outer wall of the shadow mask 25.
이러한 구성의 본 고안은 그 작용 및 효과가 다음과 같다.The present invention of such a configuration is as follows.
즉, 본 고안의 평판프레임(1)에는 새도마스크(25)의 스커트부(25a)와 직각 절곡되어 접면되는 다수의 측면직각돌출부(1a)가 연설되어 있으므로 상기 측면직각돌출부(1a)를 새도마스크(25)에 접면하여 단순히 스포트용접처리 하므로서 이들 조립기체의 결합이 완성된다.That is, in the flat frame 1 of the present invention, a plurality of side right angle protrusions 1a are folded and folded at right angles to the skirt portion 25a of the shadow mask 25, so that the side right angle protrusions 1a are new. By simply contacting the mask 25 and spot welding, the assembly of these assemblies is completed.
또, 여기서는 평판프레임(1)의 소정부위에 V형 스프링(20)을 부착하고. 이에 새도마스크(25)의 스커트부(25a)에 상기 측면 직각돌출부(1a)를 접면시켜 스포트용접처리를 행하면 되는 것이며, 이때, 전면괘널(21)과새도마스크(25)간에는 적당한 이격간격이 유지되도록 조립지그로 조정한 후 상기 스포트용접을 행하는 것이다.Here, the V-shaped spring 20 is attached to a predetermined portion of the flat plate frame 1. In this regard, the spot welding process may be performed by contacting the side right angle protrusions 1a to the skirt portion 25a of the shadow mask 25. In this case, there is a suitable spacing between the front panel 21 and the shadow mask 25. The spot welding is performed after adjusting with an assembly jig so as to be maintained.
이러한 본 고안은 칼라음극선관의 새도마스크 조립기체에 있어서, 새도마스크와 조립결합되는 평판프레임에는 새도마스크에 용이 조립 가능한 측면직각돌출부를 다수개 마련하므로서 이러한 물품의 조립 제작이 용이하고 새도마스크와의 결합부에 구조적 변형을 초래하지 않는 등의 유익한 특징이 있는 것이다The present invention, in the shadow mask assembly gas of the color cathode ray tube, the plate frame assembled with the shadow mask is provided with a plurality of side right angle protrusions that can be easily assembled to the shadow mask, so that the assembly and manufacture of such articles is easy and new It has beneficial features such as not causing structural deformation at the junction with the mask.
