본 고안은 음극선관에 관한 것으로서, 더 상세하게는 음극선관에 설치되는 디가우싱 코일(degaussing coil)의 결합구조에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly, to a coupling structure of a degaussing coil installed in the cathode ray tube.
일반적으로 텔레비젼이나 컴퓨터 모니터와 같이 음극선관이 사용되는 시스템에서는 음극선관의 자화에 의하여 스크린 화면상에 색번짐 현상이 발생할 수 있다. 디가우싱 코일은 이러한 색번짐 현상의 원인이 되는 음극선관의 자화를 방지하기 위한 것으로서, 통상 음극선관 뒤쪽의 펀넬(funnel) 외면에 설치된다.In general, in systems where a cathode ray tube is used, such as a television or a computer monitor, color bleeding may occur on a screen screen by magnetization of the cathode ray tube. The degaussing coil is to prevent magnetization of the cathode ray tube which causes the color bleeding phenomenon, and is usually installed on the outer surface of the funnel behind the cathode ray tube.
제1도는 종래의 디가우싱 코일의 체결구조를 개략적으로 도시한 음극선관의 배면도이다. 제1도에서, 참조번호21은 음극선과(20)의 뒷부분을 이루는 펀넬을, 참조번호 22는 음극선관(20)의 외주를 감싸는 Fe밴드를, 참조번호 23은 전자총이 내부에 설치되는 네크부를 각각 나타낸다.1 is a rear view of a cathode ray tube schematically showing a fastening structure of a conventional degaussing coil. In FIG. 1, reference numeral 21 denotes a funnel forming a rear portion of the cathode ray and 20, reference numeral 22 denotes a Fe band surrounding the outer circumference of the cathode ray tube 20, and reference numeral 23 denotes a neck portion having an electron gun installed therein. Represent each.
제1도에 도시된 바와 같이, 디가우싱 코일(10)은 음극선관(20)의 펀넬(21) 상에 대략 8자형으로 배치되어 있다. 그리고 그러한 배치상태를 유지하기 위하여 네 귀퉁이에서 제1고리(11)에 의하여 Fe밴드(22)에 결합되고, 중앙부에서는 제2고리(12) 및 제3고리(13)에 의하여 지지되도록 되어 있다.As shown in FIG. 1, the degaussing coil 10 is arranged in an approximately eight shape on the funnel 21 of the cathode ray tube 20. In order to maintain such an arrangement, it is coupled to the Fe band 22 by the first ring 11 at four corners, and is supported by the second ring 12 and the third ring 13 at the center.
제2도는 상기 제1고리(11)가 Fe밴드(22)에 결합된 상태를 나타낸 개략적인 사시도이다. 제2도에서 참조번호 23은 음극선관을 텔레비젼이나 모니터의 전면커버(미도시)에 고종시키기 위하여 Fe밴드(22)의 네귀퉁이에 부착된 러그를 나타낸다. 도시된 바와 같이, 제1고리(11)의 일단부에는 상기 러그(23)가 끼워질 구멍(11a)이 형성되어 있고, 타단부에는 디가우싱 코일(10)을 파지하기 위한 고리(11b) 두 개가 돌출 형성되어 있다. 즉, 디가우싱 코일(10)을 음극선관에 고정시키기 위하여 Fe밴드(22)에 부착되어 있는 러그(23)를 이용하므로, 제1고리(11)는 이 러그(23)를 수용하기에 적합한 구멍(11A)을 구비해야 하는 것이다.2 is a schematic perspective view showing a state in which the first ring 11 is coupled to the Fe band 22. In FIG. 2, reference numeral 23 denotes a lug attached to four corners of the Fe band 22 to fix the cathode ray tube to the front cover (not shown) of the television or monitor. As shown in the drawing, one end of the first ring 11 has a hole 11a into which the lug 23 is fitted, and the other end of the ring 11b for holding the degaussing coil 10. Two are protruded. That is, since the lugs 23 attached to the Fe band 22 are used to fix the degaussing coil 10 to the cathode ray tube, the first ring 11 is suitable for accommodating the lugs 23. The hole 11A should be provided.
그러나 이와 같은 종래의 디가우싱 코일 체결구조에 있어서는 디가우싱 코일을 러그를 이용하여 음극선관에 고정시키기 위하여 필연적으로 복잡한 구조의 네 개의 제1고리(11)가 별도로 준비되어야 하고 이에 따르는 불필요한 조립작업이 늘어 난다는 점에서 비능률적인 점이 있다.However, in the conventional degaussing coil fastening structure, in order to fix the degaussing coil to the cathode ray tube by using lugs, four first rings 11 having inherently complicated structures must be separately prepared and thus unnecessary assembly is required. There is an inefficiency in terms of increased work.
본 고안은 종래의 디가우싱 코일 체결구조가 갖는 상기 비능률적인 점을 개선하기 위하여 안출된 것으로서, 별도의 제1고리를 준비하지 않고도 디가우싱 코일을 Fe밴드의 네 귀퉁이에서 쉽게 결합하는 가능한 디가우싱 코일의 결합구조를 제공하는 것을 그 목적으로 한다.The present invention was devised to improve the inefficiency of the conventional degaussing coil fastening structure, and it is possible to easily combine the degaussing coil at four corners of the Fe band without preparing a separate first ring. It is an object to provide a coupling structure of a Gaussian coil.
상기 목적을 달성하기 위하여, 본 고안에 따른 디가우싱 코일 결합구조는 음극선관 외주면에 설치된 Fe밴드에 디가우싱 코일을 결합시키기 위한 디가우싱 코일 결합구조에 있어서,In order to achieve the above object, the degaussing coil coupling structure according to the present invention in the degaussing coil coupling structure for coupling the degaussing coil to the Fe band installed on the outer peripheral surface of the cathode ray tube,
상기 Fe밴드의 네 귀퉁이에는 디가우싱 코일을 파지하기 위한 고리부재가 형성되어 있고,Four corners of the Fe band is formed with a ring member for holding the degaussing coil,
디가우싱 코일은 상기 고리부재에 의해 파지되는 것을 특징으로 한다.The degaussing coil is characterized by being held by the ring member.
그리고, 상기 고리부재는 Fe밴드와 일체로 형성되는 것이 바람직하고, 위쪽을 향하여 개방되어 있는 것이 바람직하다.In addition, the ring member is preferably formed integrally with the Fe band, it is preferable that the ring member is open upward.
이하 첨부도면을 참조하여 본 고안에 따른 디가우싱 코일 결합구조를 더욱 상세하게 설명한다.Hereinafter, the degaussing coil coupling structure according to the present invention will be described in more detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 디가우싱 코일 결합구조의 일실시예를 도시한 개략적인 사시도로서, 설명의 편의를 위하여 Fe밴드의 상부만을 분리하여 나타낸 것이다.Figure 3 is a schematic perspective view showing an embodiment of the degaussing coil coupling structure according to the present invention, for the sake of convenience of description showing only the upper portion of the Fe band.
제3도에 도시된 바와 같이, 본 고안에 따른 디가우싱 코일 결합구조의 특징적인 구성요소로서, Fe밴드(22)의 네 귀퉁이에 부착되어 있는 러그(23) 옆에는 고리부재(30)가 돌출 형성되어 있다. 이 고리부재(30)는 바람직하게는 Fe밴드(22)의 가공시에 Fe밴드(22) 재료의 일부분을 절곡하여 Fe밴드(22)와 일체로 형성된다. 또는 용접, 볼트체결 또는 리켓팅 등의 적절한 방법에 의하여 Fe밴드(22) 제조시에 미리 형성될 수도 있다.As shown in FIG. 3, as a characteristic component of the degaussing coil coupling structure according to the present invention, the ring member 30 is next to the lug 23 attached to the four corners of the Fe band 22. It is formed to protrude. The ring member 30 is preferably formed integrally with the Fe band 22 by bending a portion of the Fe band 22 material during processing of the Fe band 22. Or it may be previously formed at the time of manufacturing the Fe band 22 by a suitable method such as welding, bolting or ricketing.
한편 디가우싱 코일(10)은 제3도에 도시된 바와 같이 상기 고리부재(30)에 끼워지게 된다. 따라서 디가우싱 코일(10)이 제자리에서 빠져 나오지 않게 하기 위하여는 고리부재(30)는 윗쪽으로 개방되어 있는 것이 바람직하다.Meanwhile, the degaussing coil 10 is fitted to the ring member 30 as shown in FIG. 3. Therefore, in order to prevent the degaussing coil 10 from coming out of its place, it is preferable that the ring member 30 is open upward.
제3도에는 Fe밴드(22)의 상부만이 도시되어 있지만, 하부의 구조도 상부의 구조와 완전히 동일하게 되어 있다.Although only the upper portion of the Fe band 22 is shown in FIG. 3, the structure of the lower portion is exactly the same as that of the upper portion.
또한 제3도에는 고리부재(30)가 Fe밴드(22)의 러그(23)의 바로 옆에 형성되어 있는 것만 도시되어 있지만, 이는 설명의 편의를 위한 것이므로 필요에 따라 적절한 위치에 형성될 수 있다. 그리고 네 개의 고리부재 수량도 결코 한정적인 것은 아니며, 필요에 따라 그 수를 증가하거나 감소시킬 수 있다.In addition, in FIG. 3, only the ring member 30 is shown next to the lug 23 of the Fe band 22. However, this is for convenience of description and may be formed at an appropriate position as necessary. . And the number of four ring members is also by no means limited and can be increased or decreased as needed.
본 고안에 있어서도, 종래의 디가우싱 코일 결합구조와 마찬가지로 디가우싱 코일의 배치형태는 제1도에 도시된 것과 동일하다. 그러므로, 제1도에 도시된 바와 같이 디가우싱 코일(10)은 대략 8자 형태로 배치되어 바람직하게는 네 귀퉁이에서 고리부재(30)에 의하여 지지되고 그 중앙부에서는 제2고리(12) 및 제3고리(13)에 의하여 지지된다.Also in the present invention, as in the conventional degaussing coil coupling structure, the arrangement of the degaussing coil is the same as that shown in FIG. Therefore, as shown in FIG. 1, the degaussing coil 10 is arranged in an approximately eight-character shape, preferably supported by the ring member 30 at four corners, and at the center thereof, the second ring 12 and It is supported by the third ring (13).
이상에서 설명한 바와 같이 본 고안에 따른 디가우싱 코일 결합구조에 의하면, 종래의 디가우싱 코일 결합구조에서와는 달리 디가우싱 코일을 밴드에 결합시키기 위하여 러그를 이용하지 않아도 되므로 별도의 제1고리를 준비하지 않아도 되고 이에 따른 조립작업이 단순해 진다는 실용적인 잇점이 있다.As described above, according to the degaussing coil coupling structure according to the present invention, unlike the conventional degaussing coil coupling structure, a separate first ring is not required to use a lug to couple the degaussing coil to the band. The practical advantage is that it does not need to be prepared and the assembly work is simplified accordingly.
