본 고안은 새도우마스크(Shadow Mask)가 용접고정된 프레임(Frame)과 외부의 지자계를 차폐하는 인너시일드(Inner Shield)를 결합하기 위한 인너시일드와 프레임의 결합구조에 관한 것이다.The present invention relates to an inner shield and a frame coupling structure for coupling an inner shield that shields an external geomagnetic field with a frame fixed by a shadow mask.

주지된 바와 같이 브라운관 내에 설치되면서 색선별기능을 가진 새도우마스크가 용접고정된 프레임에 외부의 전자기적 간섭으로 발생하는 브라운관내부의 불안정한 요소들을 차폐시키기 위한 인너시일드를 결합ㄱ정하게 되는데, 종래 이들의 결합은 프레임과 인너시일드가 서로 접촉되는 플랜지상에 복수의 결함공을 각각 천공한 후 이에 탄성력이 있는 다양한 형태의 클립을 끼워 결합하였으나, 이러한 결합은 프레임과 인너시일드를 안정되게 고정한 후 작업자가 이들 결합공에 복수의 클립을 일일이 체결하여야 하기 때문에 작업능률이 극히 저조할 뿐만 아니라 클립 사용으로 인해 생산원가가 상승하게 되고, 인너시일드 체결과정에서 외부의 충격으로 인한 인너시일드의 형상변형을 초래할 우려가 있으며, 또한 이들 프레임과 인너시일드에 체결된 클립이 외부의 충격으로 인해 결합공에서 빠지면서 인너시일드가 프레임으로부터 분리되어 외부의 전자기를 효과적으로 차단하지 못하므로 스크린의 품위를 저하시키는 문제점이 있었다.As is well known, a shadow mask having a color selection function installed in the CRT is combined with an inner shield for shielding the unstable elements inside the CRT generated by external electromagnetic interference to the welded frame. Joining was performed by drilling a plurality of defect holes on the flange where the frame and the inner shield contacted each other and then inserting various types of clips with elastic force.However, the joining was performed after the frame and the inner shield were stably fixed. Since a plurality of clips must be fastened to these joint holes one by one, the work efficiency is extremely low and the production cost increases due to the use of clips, and the shape of the inner shield due to external impact during the inner seal fastening process May cause damage to these frames and the inner seal. Since the clip is separated from the inner frame when the yield is for removal from the coupling hole due to an external impact it does not effectively block the external electromagnetic there is a problem of lowering the quality of the screen.

그래서 본 고안의 목적은 종래의 이러한 문제점을 감안하여 안출한 것으로 프레임과 인너시일드 결합을 간편용이하게 하여 작업효율을 향상시키고, 또한 프레임에 결합고정된 인너시일드가 외부의 충격으로 인해 프레임에서 분리되지 않도록 하여 전자기의 차폐가 잘 되도록 한 인너시일드와 프레임의 결하구조를 제공함에 있으며, 이러한 목적을 달성하기 위한 본 고안은 프레임의 일측 단부로 형성된 플랜지에 소정크기의 걸림돌기를 수개 형성하고, 인너시일드의 플랜지에는 전술한 프레임의 걸림돌기와 대응하는 결합공을 천공하여 프레임와 인너시일드가 상호 결합되도록 한 특징이 있다.Therefore, the object of the present invention was devised in view of the above-mentioned problems of the prior art, and the frame and the inner shield coupling were made easy to improve the work efficiency, and the inner seal fixed to the frame was fixed in the frame due to external impact. In order to provide a shielding structure of the inner shield and the frame so as not to separate the electromagnetic shielding well, the present invention for achieving this purpose is to form a number of hooks of a predetermined size on the flange formed at one end of the frame, The flange of the inner shield is characterized in that the frame and the inner shield are coupled to each other by drilling a coupling hole corresponding to the above-described locking projection of the frame.

이하, 본 고안의 일실시예를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 인너시일드와 프레임의 요부 분해사시도이고, 제2도는 이에 따른 인너시일드와 프레임의 결합상태를 발췌도시한 요부 측단면도로써, 패널(미도시) 내측의 스터드핀(미도시)에 고정지지되는 홀더(14)가 외측면 적소에 용접고정되어진 프레임(10) 상단부에 소정 폭의 플랜지(11)를 형성한 후 이의 장변부분에 수개의걸림돌기(12)를 적정길이로 절곡형성하고, 플랜지(11)의 단변적소에는 그 일부를 절단한 다음에 상방으로 절곡하여 수개의 고정편(13)을 형성하는 한편, 외부의 전자기를 차폐하는 인너시일드(20) 하단부에 전술한 프레임(10)의 플랜지(11)와 면접대응하는 플랜지(21)를 형성한 후 이의 장변부분에 프레임(10)의 걸림돌기(12)와 대응하는 적정길이의 결합공(22)을 수개 천공하되, 이 결합공(22)의 폭을 걸림돌기(12) 단부의 폭보다 다소 작게하여 걸림돌기(12)가 전술한 결합공(22)에 억지끼움되도록 한다.1 is an exploded perspective view of the main part of the inner shield and the frame according to the present invention, and FIG. 2 is a side cross-sectional view of the main part of the inner shield and the frame according to the present invention, and a stud pin (not shown) inside the panel (not shown). After the holder 14 fixed to the holder 14 is fixed to the outer surface of the frame 10 formed on the upper end of the flange 10 of a predetermined width to form a flange 11 of the predetermined length of the several engaging projections 12 in the appropriate length Bent to form a short edge of the flange 11, and then a portion thereof is cut and then bent upward to form several fixing pieces 13, while at the lower end of the inner shield 20 that shields external electromagnetic waves. After the flange 21 is formed in contact with the flange 11 of the frame 10 described above, a plurality of coupling holes 22 having appropriate lengths corresponding to the locking projections 12 of the frame 10 are formed on the long side thereof. Perforate the width of the coupling hole 22 than the width of the end of the engaging projection 12 It is made smaller so that the locking protrusion 12 is fitted into the above-mentioned coupling hole 22.

그리고 프레임(10)의 상단부에 플랜지(11)를 형성하여 걸림돌기(12)를 절곡형성하되, 이 걸림돌기(12)를 플랜지(11)의 장변부분 및 단변부분 모두에 형성하는 동시에 인너시일드(20)의 하단부에 마련된 플랜지(21)의 장단변 모두에 전술한 걸림돌기(12)와 대응하는 결합공(22)을 천공하여 프레임(10)과 인너시일드(20)를 결합하여도 무방하며, 프레임(10)에 마련된 플랜지(11)의 장단변 관계없이 이의 가장자리 적소에 인너시일드(20)의 외측면을 고정지지하는 고정편(13)을 절곡형성하여 프레임(10)과 결합고정된 인너시일드(20)가 측방으로 움직이지 않도록 함이 바람직하다. 또한 프레임(10)의 플랜지(11) 적소에 다수의 결합공을 천공하고 인너시일드(20)의 플랜지(23)에 전술한 결합공과 대응하는 수개의 걸림돌기를 마련하여 이들을 서로 결합하여도 무방하다.In addition, the flange 11 is formed at the upper end of the frame 10 to bend the locking protrusion 12, and the locking protrusion 12 is formed on both the long side and the short side of the flange 11, and at the same time, The frame 10 and the inner shield 20 may be coupled by drilling the coupling holes 22 corresponding to the above-described locking protrusions 12 on all of the long and short sides of the flange 21 provided at the lower end of the 20. And, regardless of the long and short sides of the flange 11 provided in the frame 10 is bent to form a fixing piece 13 for holding the outer surface of the inner shield 20 in place of the edge thereof to be fixed and coupled to the frame 10 It is preferable to prevent the inner seal 20 from moving laterally. In addition, a plurality of coupling holes may be drilled in place of the flange 11 of the frame 10, and a plurality of locking protrusions corresponding to the above-described coupling holes may be provided on the flange 23 of the inner shield 20, and these may be coupled to each other. .

이와 같이 구성된 본 고안은 제1도 및 제2도에서 보는 바와 같이 프레임(10)의 플랜지(11)에 돌출 형성된 수개의 걸림돌기(12)에 인너시일드(20)의 플랜지(21)에 천공된 결합공(22)을 맞춘 후 인너시일드(20)에 힘을 가하여 억지끼움되도록 하는 한편, 인너시일드(20)의 외측면이 프레임(10)의 플랜지(11) 가장자리로 다수 형성된 고정편(13) 내측에 면접위치하도록 함으로서 프레임(10)과 인너시일드(20)의 결합을 간편용이하게 하여 작업효율을 향상시키고, 종래와 같이 클립을 사용하지 않기 때문에 생산원가가 절감될 뿐만 아니라 프레임(10)에 결합고정된 인너시일드(20)가 흔들거리지 않도록하여 외부의 전자기를 일정하게 차폐하므로 스크린의 품위를 향상한 고안이다.The present invention configured as described above is drilled in the flange 21 of the inner shield 20 to several locking protrusions 12 protruding from the flange 11 of the frame 10 as shown in FIGS. 1 and 2. After fixing the coupling hole 22 is applied to the inner shield 20 to force the fitting, while the outer surface of the inner shield 20 has a plurality of fixing pieces formed by the edge of the flange 11 of the frame 10 (13) Improve the work efficiency by simplifying the coupling of the frame 10 and the inner shield 20 by placing the interview inside, and not only reduce the production cost because the clip is not used as in the conventional art.
