본 고안은 브라운관용 프레임의 탄성홀더구조에 관한 것으로서, 더 자세하게는 프레임의 각 모서리부분에 설치, 사용되는 탄성홀더에 관한 것이다.The present invention relates to an elastic holder structure of a frame for a CRT, and more particularly, to an elastic holder installed and used at each corner of the frame.

일반적으로 프레임 내부에는 색선별 기능을 가지면서 소정의 각도에서 입사한 전자비임만을 소망하는 형광점에 충돌할 수 있도록 하는 새도우마스크가 용접설치되고, 프레임의 사방측벽이나 각 모서리에는 판넬내에 형성된 스터드핀과 탄성적으로 결합하여 프레임내의 새도우마스크를 형광면에 균일한 간격을 유지하도록 잡아주는 다수의 탄성홀더가 용접고정된다.In general, a shadow mask is welded to the inside of the frame so that only the electron beam incident from a predetermined angle can collide with a desired fluorescent point while having a color discrimination function, and stud pins formed in panels on all four sides of the frame or at each corner thereof. A plurality of elastic holders are elastically coupled with each other to hold the shadow mask in the frame to maintain a uniform distance on the fluorescent surface.

이렇게 사용되어지는 종래의 탄성홀더중 특히 프레임의 각 모서리에 설치되는 탄성홀더구조가 제1도에 도시된 바와 같이 프레임(F)의 각 모서리(F')에 용접고정되는 고정판재(10)와; 이 고정판재(10) 일측에 그 일단이 용접되어 이 고정판재(10)와 수평되게 탄설되면서 일측으로 판넬(P)의 스터드핀(P')과 대응되는 결합공(21)이 마련된 탄성편(20); 등으로 분할구성되어 있어서 이 탄성홀더(1)의 제작공정이 극히 번거로울 뿐만 아니라, 전술한 고정판재(10)와 탄성편(20)을 상호 연결시키는 용접부위가 불량일 경우에는 프레임(F) 및 이 내부에 장착된 새도우마스크(미도시)가 판넬(P)의 형광면(P)과 균일한 간격을 유지하지 못하고 틀어짐으로써, 브라운관의 스크린 특성을 극히 저하시키는 문제점이 있었다.Among the conventional elastic holders used in this way, in particular, an elastic holder structure installed at each corner of the frame, as shown in FIG. 1, is fixed plate material 10 welded to each corner F 'of the frame F and ; One end is welded to one side of the fixed plate member 10, and the elastic piece provided with a coupling hole 21 corresponding to the stud pins P 'of the panel P on one side while being horizontally coalesced with the fixed plate member 10 ( 20); It is divided into the structure and the like, the manufacturing process of the elastic holder (1) is extremely cumbersome, and if the welding portion for connecting the fixing plate material (10) and the elastic piece (20) described above is defective, the frame (F) and The shadow mask (not shown) mounted therein does not maintain a uniform distance from the fluorescent surface P of the panel P, so that the shadow mask (not shown) has a problem of extremely deteriorating the screen characteristics of the CRT.

따라서, 본 고안은 이러한 종래의 문제점을 감안하여 안출한 것으로서, 프레임의 각 모서리와 용접고정되는 고정판재와 소정간격을 유지하도록 수평되게 절곡함으로써, 고정판재와 탄성편의 용접불량으로 인한 스크린특성 저하를 방지하는 한편, 이 탄성홀더의 제작공정을 극히 단순화시킨 브라운관용 프레임의 탄성홀더구조를 제공함에 그 목적이 있다.Therefore, the present invention has been devised in view of such a conventional problem, and by bending horizontally so as to maintain a predetermined interval with the fixed plate member welded to each corner of the frame, to reduce the screen characteristics due to poor welding of the fixed plate member and the elastic piece. On the other hand, it is an object of the present invention to provide an elastic holder structure of a frame for a CRT tube which greatly simplifies the manufacturing process of the elastic holder.

이와 같은 목적을 달성하기 위하여 본 고안은 탄성홀더를 형성함에 있어서, 프레임의 각 모서리와 용접고정되는 적정크기의 고정판재중간을 랜싱(lancing) 가공하여 일측을 제외한 나머지부분을 절단한 후 이 절단된 부분을 전술한 고정판재와 소정간격 유지하도록 수평되게 절곡하여 탄성편을 형성하여서 된 특징이 있다.In order to achieve the above object, the present invention, in forming the elastic holder, by lancing the middle of the frame and the fixed plate of the appropriate size to be welded fixed to cut the remaining portion except one side It is characterized by forming an elastic piece by bending the part horizontally so as to maintain a predetermined distance from the above-mentioned fixing plate material.

이하, 본 고안의 바람직한 일 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안에 따른 탄성홀더의 사시도이고, 제3도는 이에 따른 탄성홀더가 설치된 프레임의 요부측단면도로서, 프레임(F)의 각 모서리(F')와 용접고정되는 적정크기의 고정판재(110) 중간부위를 랜싱(lancing) 가공하여 일측을 제외한 나머지부분을 절단한 후 이 절단된 부분을 전술한 고정판재(110)와 소정간격 유지하도록 수평되게 절곡하여 탄성편(120)을 형성한다.2 is a perspective view of an elastic holder according to the present invention, and FIG. 3 is a cross-sectional side view of a main part of the frame in which the elastic holder is installed, and the fixed plate member of the appropriate size fixed to each edge (F ') of the frame (F) by welding. 110) After lancing the intermediate portion to cut the remaining portion except one side, the cut portion is bent horizontally to maintain a predetermined distance with the above-described fixing plate 110 to form an elastic piece 120.

이렇게 탄성편(120)이 완성되면, 이의 일측에 판넬(P)의 스터드핀(P')과 대응결합하여 프레임(F) 및 새도우마스크(미도시)를 판넬(P)의 형광면(P)으로부터 일정하게 유지시켜주는 결합공(121)을 형성한다.When the elastic piece 120 is completed as described above, the frame F and the shadow mask (not shown) are correspondingly coupled to the stud pins P 'of the panel P on one side thereof from the fluorescent surface P of the panel P. Forming a coupling hole 121 to maintain a constant.

위에서 설명한 탄성홀더(100)의 구조는 본 고안의 한 가능한 실시예에 불과하며, 예컨대 전술한 탄성홀더(100)를 프레임(F)과 일체로 형성하여도 된다. 즉, 프레임(F)의 각 모서리(F')를 랜싱 가공하여 탄성편(120)을 모서리(F')로부터 수평되게 절곡형성하여도 무방하며, 전술한 탄성홀더(100)의 형상은 앞서 설명한 본 고안의 범위내에서 얼마든지 그 변경이 가능하다.The structure of the elastic holder 100 described above is only one possible embodiment of the present invention, for example, the above-described elastic holder 100 may be formed integrally with the frame (F). That is, the angular processing of each edge (F ') of the frame (F) may be formed to bend the elastic piece 120 horizontally from the corner (F'), the shape of the elastic holder 100 described above Any change is possible within the scope of the present invention.

이와 같이 본 고안은 소정크기의 고정판재(110)를 랜싱 가공한 다음, 이 절단된 부위를 절곡하여 결합공(121)을 가진 탄성편(120)을 형성한 후 제3도와 같이 전술한 고정판재(110)를 프레임(F)의 각 모서리(F')에 용접고정한 다음, 전술한 탄성편(120)의 결합공(121)을 판넬(P) 내면의 스터드핀(P')에 각각 탄설한다.As described above, after the lancing processing of the fixed plate member 110 of a predetermined size, the cut portion is bent to form the elastic piece 120 having the coupling hole 121, and the fixed plate member described above as shown in FIG. After fixing 110 to each corner F 'of the frame F, the coupling holes 121 of the elastic piece 120 are mounted on the stud pins P' on the inner surface of the panel P, respectively. .

전술한 바와 같이 본 고안은 프레임(F)의 각 모서리(F')와 용접고정되는 고정판재(110)의 일부를 절단한 후 이 절단된 부분, 즉 탄성편(120)을 전술한 고정판재(110)와 소정간격을 유지하도록 수평되게 절곡함으로써, 탄성홀더(100)의 불량을 극소화시켜 스크린특성 저하를 방지하는 한편, 이 탄성홀더(100)의 제작공정을 극히 단순화시킨 효과가 있다.As described above, the present invention cuts a part of the fixed plate member 110 that is welded and fixed to each edge F 'of the frame F, and then cuts the cut portion, that is, the elastic piece 120 as described above. By bending horizontally to maintain a predetermined distance from the 110, the defect of the elastic holder 100 is minimized to prevent degradation of the screen characteristics, and the manufacturing process of the elastic holder 100 is extremely simplified.
