제2도는 제1도의 실시예의 새도우 마스크 구조체의 일부 확대사시도,2 is a partially enlarged perspective view of the shadow mask structure of the embodiment of FIG.

제3도는 제1도의 실시예의 새도우 마스크 구조체를 환경자게에 대하여 팽팽하게 배치한 경우의 자속선의 상태를 도시한 도면.3 is a view showing a state of magnetic flux lines in a case where the shadow mask structure of the embodiment of FIG.

Claims (4)

새도우 마스크(4)가 패널부(1c)의 스커트부에 따라서 브라운관 축방향을 연장하는 프레임(5)의 측벽부에 부착되어 있는 새도우 마스크 구조체(20)을 마련한 컬러음선관에 있어서, 상기 프레임(5)의 측벽부에 안둘레면에 따라서 주위를 둘러싸도록 마련한 띠형상의 제1의 자기차폐부재(11) 또는 해당 측벽부의 바깥둘레면에 따라서 주위를 둘러싸도록 마련한 띠형상의 제2의 자기차폐부재(12) 또는 상기 띠형상의 제1 및 제2의 차폐부재를 마련한 컬러음극선관.In a color sound tube in which a shadow mask 4 is provided with a shadow mask structure 20 attached to the side wall portion of the frame 5 extending in the axial direction of the CRT along the skirt portion of the panel portion 1c. 5) a strip-shaped first magnetic shield member 11 provided to surround the periphery along the inner circumferential surface of the side wall portion or a strip-shaped second magnetic shield provided to surround the periphery along the outer circumferential surface of the side wall portion 5). The color cathode ray tube provided with the member 12 or the said strip | belt-shaped 1st and 2nd shielding member. 특허청구의 범위 제1항에 있어서, 상기 띠형상의 제1및 제2의 자기차폐부재 (11,12)가 프레임보다 투자율이 높은 재료로 형성되며, 또한 상기 프레임(5)에 자기저항이 큰 상태로 부착되는 컬러음극선관.2. The belt-shaped first and second magnetic shield members 11 and 12 are formed of a material having a higher permeability than the frame, and the frame 5 has a high magnetic resistance. Color cathode ray tube attached in state. 새도우 마스크가 프레임의 측벽부에 부착되어 있고, 또한 상기 프레임의 각 측벽부를 연장하는 형태로 퍼넬내를 덮은 각진 받침대 형상으로 형성된 내부자기 차폐부재가 부착되어 있는 새도우 마스크 구조체(20)를 마련한 컬러음극선관에 있어서, 상기 프레임의 측벽부와 상기 측벽부에 이어서 퍼넬내에 연장하여 퍼넬내의 일부를 덮는 각진 받침대 형상으로 형성되어 있는 연장부로 구성되어 있고, 또한 상기 연장부의 후단부에 상기 내부 자기차폐부지가 자기 저항이 작은 상태로 부착되는 컬러음극선관.A color cathode ray provided with a shadow mask structure 20 to which a shadow mask is attached to the side wall portion of the frame, and to which an internal magnetic shield member is formed, which is formed in an angled pedestal shape covering the inside of the funnel so as to extend each side wall portion of the frame. The tube includes a side wall portion of the frame and an extension portion formed in an angled pedestal shape extending in the funnel and covering a portion of the funnel, followed by the side wall portion of the frame. Colored cathode ray tube attached with a low magnetic resistance. 특허청구의 범위 제3항에 있어서, 상기 프레임의 새도우 마스크보다 투자율이 높은 재료로 형성되는 새도우 마스크 방법의 컬러음극선관.The color cathode ray tube according to claim 3, wherein the shadow mask method of the shadow mask method is formed of a material having a higher permeability than the shadow mask of the frame. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
