제2도는 본 고안에 따른 프레임/인너실드의 결합상태를 도시한 분해 사시도이고 제 3도는 이에 따른 프레임/인너실드의 결합상태를 발췌도시한 요부측단면도로서, 프레임(F)과 인너실드(I)를 상호 결합시킴에 있어서 전술한 인너실드(I)의 플랜지(I)단부에 적정간격를 두고 다수의 고정편(C)을 측방으로 돌출되게 형성한 다음 이 제1고정편(C)을 프레임(F)의 플랜지(F)에 절곡시켜 전술한 프레임(F)과 인너실드(I)를 일차 결합시키는 한편, 상기 프레임(F)의 플랜지(F)와 근접된 인너실드(I)측벽의 여러 개소의 랜싱(lancing)가공을 이용하여 복수의 제2고정편(C')을 형성한 다음 상기 제2공정편(C)을 프레임(F) 측벽에 형성된 다수의 결합공(F)에 끼움, 절곡시켜 전술한 프레임(F)과 인너실드(I)를 마지막으로 결합한다.FIG. 2 is an exploded perspective view illustrating a coupling state of a frame / inner shield according to the present invention, and FIG. 3 is a main sectional side view illustrating the coupling state of the frame / inner shield according to the present invention, and the frame F and the inner shield I are illustrated in FIG. ) When the plurality of fixing pieces (C) are formed to protrude laterally at appropriate intervals on the flange (I) end of the inner shield (I) mentioned above, the first fixing piece (C) is formed in the frame ( By bending to the flange (F) of F), the above-mentioned frame (F) and the inner shield (I) are first coupled, while several places on the inner wall (I) side wall adjacent to the flange (F) of the frame (F). After forming a plurality of second fixing piece (C ') by using a lancing processing of the second process piece (C) is fitted into a plurality of coupling holes (F) formed on the side wall of the frame (F), bending The frame F and the inner shield I are finally combined.
위에서 설명한 프레임(F)와 인터실드(I)의 결합구조는 본 고안의 한가능한 실시예에 불과하며 예컨대 전술한 인너실드(I)의 플랜지(I') 및 측벽에 형성된 고정편(C)(C')의 형상은 앞서 설명한 본 고안의 범위내에서 얼마든지 그 변경이 가능하다.The coupling structure of the frame F and the intershield I described above is only one possible embodiment of the present invention, and for example, the fixing piece C formed on the flange I 'and the sidewall of the inner shield I described above ( The shape of C ') can be changed as many as possible within the scope of the present invention described above.
이와 같이 구성된 본 고안의 작용 및 효과를 상세히 설명한다.The operation and effects of the present invention configured as described above will be described in detail.
전술한 프레임(F)에 외부지자계를 차폐시키는 인너실드(I)를 결합, 고정시키고자 할 시에는 제2도시한 바와 같이 전술한 인너실드(I)의 플랜지(I') 및 측벽에 다수의 고정편(C)(C')을 형성한 다음 제3도와 같이 제1고정편(C)은 프레임(F)의 플랜지(F')에 각각 절곡, 고정시키고 제2고정편(C')은 프레임(F)측벽에 형성된 다수의 결합공(F)에 끼움, 절곡시켜 전술한 프레임(F)과 인너실드(I)을 상호 결합시킨다.In order to couple and fix the inner shield I shielding the external geomagnetic field to the above-mentioned frame F, as shown in FIG. 2, a plurality of inner shields I may be formed on the flange I 'and the side wall of the inner shield I. After forming the fixing piece (C) (C ') of the first fixing piece (C) is bent, fixed to the flange (F') of the frame (F), respectively, as shown in Figure 3 and the second fixing piece (C ') Is fitted into a plurality of coupling holes (F) formed on the side wall of the frame (F) and bent to couple the aforementioned frame (F) and the inner shield (I) to each other.
따라서 본 고안을 전술한 인너실드(I)의 여러 개소에 이와 일체로 형성된 고정편(C)(C')을 프레임(F)적소마다 절곡시켜 프레임(F)와 인너실드(I)를 상호 결합시킴으로써 이들의 결합작업을 간편 용이하게 할 수 있도록 함은 물론 이고 외부의 어떠한 충격에도 인너실드가 프레임으로부터 분리되지 않도록 결합시킴으로써 브라운관의 품위를 향상시킨 효과가 있다.Therefore, the present invention is a combination of the frame (F) and the inner shield (I) by bending the fixing piece (C) (C ') formed integrally therewith in several places of the inner shield (I) described above for each frame (F). By doing so, the joining operation can be easily facilitated, and the inner shield is combined so that the inner shield is not separated from the frame under any external shock, thereby improving the quality of the CRT.
