Description
본 발명은 새도우 마스크형 칼라 수상관에 관한 것으로서, 특히 칼라수상관 내의 새도우마스크를 지지하는 프레임에 지자계 차폐용 쉴드가 용이하게 결합될 수 있도록 하여 자기쉴드의 탈락 현상을 감소시키기 위한 자기쉴드 결합구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shadow mask type color receiving tube, and in particular, a magnetic shield coupling for reducing the dropping of the magnetic shield by allowing the magnetic field shielding shield to be easily coupled to a frame supporting the shadow mask in the color receiving tube. It's about structure.
일반적인 칼라 수상관은 제 1도에 도시된 바와 같이 새도우마스크(3)가 프레임(3b)에 결합되며, 상기 프레임(3b)은 다시 스프링(3c)에 용접 결합되어 판넬(1)에 고정된 판넬핀(1a)에 새도우마스크 조립체가 장착되고, 상기 새도우마스크(3)의 지지체인 프레임(3b)의 후방에 외부자계를 차폐하기 위한 자기쉴드(102)를 픽싱스프링(11)을 이용하여 결합하고, 판넬(1)과 융착되는 펀넬(2)의 네트부(8)에 전자빔(10)을 발산하는 전자총(7)을 장착함으로 구성된다.As shown in FIG. 1, a general color water tube includes a shadow mask 3 coupled to a frame 3b, and the frame 3b is again welded to a spring 3c and fixed to the panel 1. The shadow mask assembly is mounted on the pin 1a, and the magnetic shield 102 for shielding the external magnetic field is connected to the rear of the frame 3b, which is a support of the shadow mask 3, using a fixing spring 11, And an electron gun 7 for emitting an electron beam 10 to the net portion 8 of the funnel 2 fused to the panel 1.
이와 같이 구성된 칼라 수상관은 전자총(7)으로부터 방출된 전자빔(10)이 편향요크(5)에 의해 편향된 후 새도우마스크(3)에 형성된 구멍을 통과하여 형광막(9)에 충돌하므로서 형광체 화소를 발광시키게 되며, 이때 자기쉴드(4)는 제 2 도 및 제 3도와 같이 프레임(3b)의 후사면에 픽싱스프링(11)을 관축(A)에 대하여 평행한 방향으로 삽입하여 고정되게 된다.The color receiving tube configured as described above causes the electron beam 10 emitted from the electron gun 7 to be deflected by the deflection yoke 5 and then passes through the hole formed in the shadow mask 3 to impinge on the phosphor film 9 so as to impinge on the phosphor pixel. In this case, the magnetic shield 4 is fixed by inserting the fixing spring 11 in a direction parallel to the tube axis A on the rear surface of the frame 3b as shown in FIGS. 2 and 3.
일반적으로 자기쉴드(4)는 고투자율재질을 사용하여 제작되며 외부자계가 변화하게 되었을 때는 소자코일(6)에 교류전류를 흘려서 소자작용에 의해 외부자계가 차폐될 수 있도록 되어있다.In general, the magnetic shield 4 is manufactured using a high permeability material, and when the external magnetic field is changed, the external magnetic field is shielded by the device action by flowing an alternating current through the device coil 6.
이러한 자기쉴드의 조립작업은 제 3도에서와 같이 자기쉴드(4)에 형성된 삽입공과 프레임(3b)에 형성된 삽입공을 서로 일치시킨후 픽싱스프링(11)을 삽입하게 되는데, 이때 픽싱스프링(11)의 끝단을 작업자가 압축하여 삽입공에 삽입하면 삽입후에는 자기쉴드(4)와 프레임(3b)이 픽싱스프링(11)의 탄성력에 의해 밀착 고정된다.In the assembling of the magnetic shield, as shown in FIG. 3, the insertion hole formed in the magnetic shield 4 and the insertion hole formed in the frame 3b coincide with each other, and then the fixing spring 11 is inserted. When the operator presses the end of the clamp into the insertion hole, the magnetic shield 4 and the frame 3b are tightly fixed by the elastic force of the fixing spring 11 after insertion.
그러나 종래 이러한 조립방식은 자기쉴드와 프레임이 탄탄하게 밀착 조립되기 힘들며 자기쉴드가 프레임에 끼워져서 빠지지 않을 정도로 된 형태로서, 반드시 유격이 존재하여 외부자계 차페시, 특히 음극선관이 저립된 모니터를 온/오프할 경우 발생되는 교류자장에 의해 자기쉴드의 진동이 유발되어 진동음이 발생하게 되며, 이로 인하여 자기쉴드의 결합작업시 세심한 주의가 요구되는 작업상의 문제점이 있었다.However, such a conventional assembly method is difficult to assemble the magnetic shield and the frame tightly and the magnetic shield is inserted into the frame so that it does not fall out, there is necessarily a gap in the external magnetic field, especially the cathode ray tube is installed on the monitor The vibration of the magnetic shield is caused by the alternating magnetic field generated when the / off is generated, the vibration sound is generated, which has a problem in the work that requires careful attention when combining the magnetic shield.
본 발명은 이러한 점을 감안하여 프레임과 자기쉴드의 결합부에 관축방향에 대하여 직각방향으로 결합되는 고정스프링을 구비함으로서, 고정스프링의 적절한 탄성력으로 상기 부품을 결합시키고 결합작업을 용이하게 수행할 수 있도록 하는데 목적이 있다.The present invention has a fixed spring coupled to the frame and the magnetic shield in the coupling portion at right angles to the tube axis direction in view of this point, it is possible to easily combine the components and the coupling operation with a suitable elastic force of the fixed spring. The purpose is to make it work.

본 발명을 제 4 도 및 제 5도를 참조하여 이하에서 상세히 설명한다.The invention is described in detail below with reference to FIGS. 4 and 5.
먼저 구성을 살펴보면 프레임(101)과 자기쉴드(102)의 결합부에 관축방향에 대하여 직각방향으로 결합, 고정시키는 고정스프링(103)을 구비하였으며, 상기 고정스프링(103)은 탄성력에 의하여 고정력을 높이도록 개구부(103')의 폭(A)을 프레임(101)과 자기쉴드(102)의 결합부 폭(B)보다 작게 구성하였다.Looking at the configuration first, the coupling portion of the frame 101 and the magnetic shield 102 was provided with a fixing spring 103 for coupling and fixing in a direction perpendicular to the tube axis direction, the fixing spring 103 is a fixed force by the elastic force The width A of the opening 103 'was made smaller than the width B of the coupling portion of the frame 101 and the magnetic shield 102 so as to be high.
즉, 음극선관의 조립공정에서 프레임(101)과 자기쉴드(102)를 결합시키는 작업시는 ㄷ자 형상으로 구비된 본 발명의 고정스프링(103)을 이용하여 제 4도와 같이 결합시킨다.That is, in the assembling process of the cathode ray tube, the frame 101 and the magnetic shield 102 are coupled to each other as shown in FIG. 4 by using the fixing spring 103 of the present invention having a C shape.
이때 고정스프링(103)의 개구부(103')폭(A)은 제 5도에서와 같이 프레임(101)과 자기쉴드(102)의 결합두께(B)보다 약 10%정도 적기 때문에 고정스프링(103) 자체의 탄성력에 의하여 결합체를 결합시키게 되는 것이다.At this time, the opening 103 'width A of the fixed spring 103 is about 10% less than the coupling thickness B of the frame 101 and the magnetic shield 102, as shown in FIG. ) It is to combine the combination by its elastic force.
이상에서 살펴본 바와같은 본 발명은 음극선관의 온/오프시 교류자장에 의해 발생되는 자기쉴드의 진동음을 저감시킬 수 있으며, 자기쉴드와 프레임의 결합구조를 단순하게 하여 부품의 제조공정을 단축시킬 수 있도록 하는 발명이다.The present invention as described above can reduce the vibration sound of the magnetic shield generated by the alternating magnetic field when the cathode ray tube on / off, and can simplify the manufacturing process of parts by simplifying the coupling structure of the magnetic shield and the frame. It is an invention to make.
