본 고안은 모니터, 텔레비젼등의 브라운관의 요크부에 장설된 편향 코일이 전자파에 의해 매우 심한 간섭을 받는 것을 차폐하도록 된 브라운관의 요크(Yoke)부 차폐 장치에 관한 것이다.The present invention relates to a yoke shielding device of a cathode ray tube, which is configured to shield a deflection coil installed in the yoke portion of a cathode ray tube such as a monitor or a television from being subjected to extremely severe interference by electromagnetic waves.

종래에는 브라운관의 요크부위에 영향을 주게되는 전자파를 차폐하기 위해 주로 알루미늄 박판으로 된 차폐막을 인쇄회로 기판 전방에 위치시켜 차폐하였던바, 이는 전자파가 차폐막 사이의 측방을 통하여 유출되어 상기 요크부위의 편향 코일에 영향을 주게 되므로 차폐막으로서의 제기능을 다할 수 없었던 결점이 있었다.Conventionally, in order to shield the electromagnetic wave affecting the yoke portion of the CRT, a shielding film mainly made of aluminum is placed in front of the printed circuit board to shield the electromagnetic wave, and the electromagnetic wave flows out through the sides between the shielding films to deflect the yoke portion. There was a drawback that the coil could not be functioned as a shielding film because it would affect the coil.

따라서 본 고안은 상기한 바와 같은 종래 차폐막의 결점을 해결코져 안출된 것으로서 특히 요크부위의 편향 코일이 외부로부터 발생되는 전자파를 거의 완벽하게 차폐할 수 있고, 또 구성 및 조립이 극히 간편한 차폐장치를 제공하는데 그 목적이 있는 것으로 이하 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention solves the drawbacks of the conventional shielding film as described above, and particularly, the deflection coil of the yoke part can almost completely shield electromagnetic waves generated from the outside, and provide a shielding device that is extremely easy to configure and assemble. It will be described in detail based on the accompanying drawings to the purpose as follows.

브라운관(1)의 요크부(2)에 권착된 편향코일(3)에 외부로부터의 전자파를 차단되도록 한 것에 있어서, 상기 요크부(2)에 전자파등을 용이하게 차폐토록 한 차폐 캡(4)을 브라운관(1)의 후방에서부터 끼워 장설하되, 상기 차폐 캡(4)은 요크부(2)의 후방에서 상,하부에 형성된 차단판(5)(5')에 일치되도록 상,하부에 각각 걸림환턱(6) 및 삽입접촉면(6')를 형성하고, 또 상부 전후방에는 요크부(2) 상면에 돌출되는 전선 연결부(7)등을 감인하여 "U"형의 요부(8)를 형성하였으며, 차폐 캡(4)이 요크부(2)에 삽설된 후에 요크부(2)로부터 빠지거나 이탈되지 않도록 일측부에 탄성이 양호한 고정핀(9)으로서 고정시키도록 된 브라운관의 요크부 차폐 장치인 것이다.A shielding cap (4) which allows electromagnetic waves from the outside to be blocked by the deflection coil (3) wound on the yoke portion (2) of the CRT (1). To be installed from the rear of the CRT (1), the shielding cap (4) is fastened to the upper and lower, respectively, so as to match the blocking plate (5) (5 ') formed in the upper, lower portion in the rear of the yoke (2) The round jaw 6 and the insertion contact surface 6 'were formed, and the front and rear portions of the U-shaped recess 8 were formed by allowing the wire connecting portion 7 to protrude on the upper surface of the yoke portion 2, etc. After the shielding cap 4 is inserted into the yoke portion 2, the yoke portion shielding device of the CRT is fixed to one side as a fixing pin 9 having good elasticity so as not to be pulled out or separated from the yoke portion 2. .

미설명부호 10은 브라운관의 샤시, 11,11'는 인쇄회로 기판이다.Reference numeral 10 denotes a chassis of the CRT, and 11 and 11 'are printed circuit boards.

위와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

브라운관(1)의 요크부(2)에 본 고안의 차폐 캡(4)을 삽설할 때는 브라운관(1)의 후미로부터 삽입시키도록 하는데, 차폐 캡(4)이 상협하광으로 형성되어 있고 또 차폐 캡(4) 상측부 전후방에 "U"형의 요부(8)를 형성하였으므로, 요크부(2)에 장설된 선들의 영향을 받지 않으면서 차폐 캡(4)을 순조롭게 삽입할 수 있으며, 또한 완전히 삽입한 후에는 차폐 캡(4)의 상부 걸림환턱(6)이 요크부(2)의 상측 외주면에 의해 걸리게 되면서 차폐 캡(4)의 하부 삽입 접촉면(8')이 요크부(2)의 하측 차단판(5')의 외주연부에 접촉하게 되며, 이 상태에서 고정편(9)을 차폐 캡(4) 일측에 끼워 고정시키면 차폐 캡(4)이 요크부(2)로부터 빠지는 일 없이 견고하게 고정되는 것으로 샤시(10) 내부에 장설된 인쇄회로 기판(11)(11')등에서 발생하는 극심한 전자파의 간섭을 매우 간편하게 차폐할 수 있는 효과가 있는 것이다.When inserting the shielding cap 4 of the present invention into the yoke portion 2 of the CRT 1, it is to be inserted from the rear of the CRT 1. The shielding cap 4 is formed by upper and lower light and the shielding cap. (4) Since the U-shaped recesses 8 are formed in the front and rear of the upper part, the shielding cap 4 can be smoothly inserted without being affected by the lines installed in the yoke portion 2, and also fully inserted. After the upper locking ring 6 of the shielding cap 4 is caught by the upper outer circumferential surface of the yoke portion 2, the lower insertion contact surface 8 ′ of the shielding cap 4 blocks the lower side of the yoke portion 2. When the fixing piece 9 is fixed to one side of the shielding cap 4 in this state, the shielding cap 4 is firmly fixed without falling out of the yoke portion 2. This makes it very easy to shield the interference of extreme electromagnetic waves generated from the printed circuit boards 11 and 11 'installed inside the chassis 10. It can be effective.

상술한 바와 같이 본 고안은 브라운관(1)의 요크부(2)에 꼭 맞도록 제작된 차폐 캡(4)을 상기 요크부(2)에 삽설하도록 함으로서 조립이 극히 간편하고, 또 전자파의 차폐가 확실하며 제작이 손쉬워 저렴한 값으로 널리 보급할 수 있는 유용한 고안인 것이다.As described above, the present invention inserts the shielding cap 4 manufactured to fit into the yoke portion 2 of the CRT 1 to the yoke portion 2, so that the assembly is extremely simple and the shielding of electromagnetic waves It is a useful design that can be widely used at a reasonable price because it is easy to manufacture.
