Description
본 고안은 일부에 주름을 형성하여 지자계의 차폐효과를 높인 음극선관용 인너실드에 관한 것이다.The present invention relates to an inner shield for cathode ray tubes with a wrinkle formed in part to increase the shielding effect of the geomagnetic field.
일반적으로 음극선관에 있어서 전자총으로부터 발사된 전자빔은 편향요크에 의하여 편향되어 일정한 패턴으로 빔통과구멍이 형성된 새도우마스크를 통과하여 패널의 안쪽연예 일정한 패턴으로 형성된 형광막에 조사되어 형광체를 발광시키므로서 소정의 영상을 재현한다.In general, an electron beam emitted from an electron gun in a cathode ray tube is deflected by a deflection yoke, passes through a shadow mask in which a beam passage hole is formed, and is irradiated to a fluorescent film formed in a predetermined pattern inside the panel to emit a phosphor. To reproduce the image.
상기와 같이 전자빔이 편향요크에 의하여 편향되어 새도우마스크로 진행할 때에 외부 지자기의 영향으로 전자빔의 진행방향에 변화가 생겨 화면이 왜곡되는 것을 방지하기 위하여 새도우마스크의 지지체인 마스크프레임에 소정의 투자율을 보유한 얇은 금속판으로 형성된 인너실드를 장착하며 외부 지자기를 차폐한다.As described above, when the electron beam is deflected by the deflection yoke and proceeds to the shadow mask, the magnetic beam has a predetermined permeability to the mask frame, which is the support of the shadow mask, to prevent the screen from being distorted due to the change in the direction of the electron beam due to the influence of external geomagnetism. It is equipped with an inner shield formed by a thin metal plate and shields the external geomagnetic.
상기한 인너실드는 얇은 평판을 이용하여 대략 사각튜브형상으로 제작되고, 지자기가 전자빔에 영향을 미치는 것을 방지하기 위하여 인너실드에 충진되거나 분산되도록 작용한다.The inner shield is manufactured in a substantially square tube shape using a thin plate, and acts to be filled or dispersed in the inner shield to prevent the geomagnetism from affecting the electron beam.
상기와 같이 구성되는 종래 인너실드는 평판으로 형성되기 때문에 지자기의 차폐효파를 높이기 위하여 한정된 음극선관의 내부공간에서 인너실드의 체적을 증가시키는 데에 한계가 있다는 문제가 있다.Since the conventional inner shield configured as described above is formed as a flat plate, there is a problem in that there is a limit in increasing the volume of the inner shield in the inner space of the cathode ray tube limited to increase the shielding effect of the geomagnetic.
본 고안의 목적은 상기한 문제점을 해결하기 위한 것으로서, 일부에 주름부를 형성하여 체적을 증가시킨 음극선관용 인너실드를 제공하는 것이다.An object of the present invention is to solve the above problems, to provide an inner shield for the cathode ray tube to increase the volume by forming a wrinkle portion in part.
본 고안 음극선관용 인너실드는 위쪽 일부에 둘레를 따라서 복수의 주름을 형성한 주름부가 제공된다.The inner shield for the cathode ray tube of the present invention is provided with a pleat formed with a plurality of pleats along a circumference thereof.
상기한 주름은 4∼5개를 형성하는 것이 바람직하다.It is preferable that the said wrinkles form 4-5 pieces.
상기와 같이 복수의 주름이 형성된 본 고안이 음극선관용 인너실드에 의하면 지자기를 차폐하는 체적이 크게 증가되므로 지자기의 차폐효과가 향상된다.According to the present invention having a plurality of wrinkles as described above, the inner shield for the cathode ray tube increases the volume of shielding the geomagnetism, thereby improving the shielding effect of the geomagnetism.
도 1은 본 고안에 따른 음극선관응 인너실드의 일실시예를 나타내는 사시도.1 is a perspective view showing an embodiment of a cathode ray-resistant inner shield according to the present invention.

다음으로 본 고안에 따른 음극선광용 인너실드의 가장 바람직한 실시예를 도면을 참조하여 상세하게 설명한다.Next, the most preferred embodiment of the cathode shield inner light shield according to the present invention will be described in detail with reference to the drawings.
먼저 도 1에 나타낸 바와 같이, 본 고안에 따른 음극선관용 인너실드의 일실시예는 상기 인너실드(2)의 몸체를 형성하는 둘레부(3)의 상측 부위 둘레를 따라서 복수의 주름을 형성한 주름부(4)가 제공된다.First, as shown in FIG. 1, one embodiment of the inner shield for the cathode ray tube according to the present invention is a wrinkle formed by forming a plurality of wrinkles around the upper portion of the periphery 3 forming the body of the inner shield 2. Part 4 is provided.
상기한 주름은 4∼5개를 형성하는 것이 바람직하다.It is preferable that the said wrinkles form 4-5 pieces.
상기와 같이 본 고안에 따른 음극선관용 인너실드(2)에 의하면 전자총에서 발사된 전자빔이 진행할 때에 영향을 미치는 지자기와 접하는 면적이 복수의 주름이 형성된 상기한 주름부(4)에 의하여 크게 확장되고 체적도 크게 증가되므로 지자기의 차폐효과가 향상된다.According to the inner shield (2) for the cathode ray tube according to the present invention as described above, the area in contact with the geomagnetism that affects when the electron beam emitted from the electron gun proceeds is greatly expanded by the pleats (4) having a plurality of pleats formed and volume In addition, the shielding effect of the geomagnetic is improved because it is greatly increased.
상기에서는 본 고안의 바람직한 실시예에 대하여 설명하였지만, 본 고안은 이에 한정되는 것이 아니고 실용신안등록 청구의 범위와 고안의 상세한 설명 및 첨부한 도면의 범위 안에서 여러 가지로 변형하여 실시하는 것이 가능하고 이 또한 본 고안의 범위에 속하는 것은 당연하다.In the above description of the preferred embodiment of the present invention, the present invention is not limited to this, but can be implemented in various ways within the scope of the utility model registration claims and the detailed description of the invention and the scope of the accompanying drawings. It is also natural to fall within the scope of the present invention.
상기와 같이 이루어지는 본 고안 음극선관용 인너실드에 의하면, 지자기의 차폐효과가 향상되므로 지자기에 의하여 발생하는 화면의 왜곡을 방지할 수 있다.According to the inner shield for the cathode ray tube of the present invention made as described above, since the shielding effect of the geomagnetism is improved, distortion of the screen caused by the geomagnetism can be prevented.
