Abstract

본 고안은 음극선관의 개선된 러그를 개시한다.The present invention discloses an improved lug of a cathode ray tube.

종래에는 방폭밴드에 접촉하는 고정부가 평활하게 구성되었으므로 외부요인에 의해 미끄러져 틸트되는 등 음극선관에 대한 정확한 상대위치를 유지할 수 없었다.In the related art, since the fixing part contacting the explosion-proof band is smoothly configured, it is not possible to maintain an accurate relative position with respect to the cathode ray tube such as being tilted by an external factor.

본 고안에서는 방폭밴드에 접촉하는 고정부에 다수의 마찰돌기를 구비하여, 방폭밴드와의 접촉 마찰력을 증대시킴으로써 외부요인에 의한 미끄러짐이 최대한 억제되도록 하였다.In the present invention, a plurality of friction protrusions are provided on the fixing part in contact with the explosion-proof band, thereby increasing the contact frictional force with the explosion-proof band so that slippage due to external factors is suppressed as much as possible.

본 고안은 음극선관(cathode ray tube)에 관한 것으로, 더 상세하는 음극선관을 화상장치내에 고정하는데 사용되는 러그(lug)에 관한 것이다.The present invention relates to a cathode ray tube, and to a lug used to fix a more detailed cathode ray tube in an imager.

제1도에서, 음극선관(T)이 완성되고 나면, 이는 TV나 모니터(monitor) 등을 구성할 화상장치(S)내에 장착되어 소정의 제품을 구성하게 된다. 이를 위해 음극선관(T)의 패널(panel; P) 스커어트(skirt; K) 네 모서리에는 이를 화상장치(S)내에 고정하기 위한 복수의 러그(1)가 구비되는데, 이 러그(1)는 화상장치(S)내에서는 음극선관(T)의 위치를 결정하게 된다. 이에따라 음극선관(T)에 대한 러그(1)의 상대위치, 즉 패널(P)면 소정위치로부터의 러그높이와 각 러그(1)간의 피치(pitch) 등이 적절한 정도로 관리되어야 할 뿐만 아니라 음극선관(T)에 견고하게 고정되어야 한다.In FIG. 1, after the cathode ray tube T is completed, it is mounted in an image device S which will constitute a TV, a monitor, or the like to constitute a predetermined product. To this end, a plurality of lugs 1 are provided at four corners of the panel P and skirt K of the cathode ray tube T to fix them in the image device S. The lugs 1 In the image device S, the position of the cathode ray tube T is determined. Accordingly, the relative position of the lug 1 with respect to the cathode ray tube T, that is, the height of the lug from the predetermined position of the panel P plane and the pitch between each lug 1 should be managed to an appropriate degree, as well as the cathode ray tube. It must be firmly fixed in (T).

이와같은 러그(1)는 통상 대기압에 의한 음극선관(T)의 폭축(implosion)을 방지하기 위해 패널(P)의 스커어트(K) 외주에 감겨지는 방폭밴드(防爆 band; B)에 의해 음극선관(T)에 고정되는데, 그 고정방식으로는 용접으로 접합하는 방식과 패널(P)과 방폭밴드(B)간에 개재시키는 방식이 일반적으로 사용된다.Such a lug 1 is a cathode ray by an explosion-proof band B wound around the outer periphery of the panel P of the panel P in order to prevent the expansion of the cathode ray tube T due to atmospheric pressure. It is fixed to the pipe (T), and the method of joining by welding and the method of interposing between the panel (P) and the explosion-proof band (B) are generally used.

제2도에는 이중 후자의 고정방식을 도시하였는데, 이것은 ㄱ형 러그(1)의 고정부(2)를 음극선관(T)의 패널(P) 스커어트(K)와 방폭밴드(B) 사이에 위치시켜 밴딩(banding)시 방폭밴드(B)의 인장력에 의해 고정하는 것이다. 나머지 부호 3은 러그(1)의 이어(ear)이고, 3a는 이어를 세트(S)에 고정하기 위한 관통구멍이다.Figure 2 shows the latter fixing method, in which the fixing part 2 of the a-type lug 1 is located between the panel P skirt of the cathode ray tube T and the explosion-proof band B. It is to be fixed by the tensile force of the explosion-proof band (B) when bending. The remaining symbol 3 is an ear of the lug 1, and 3a is a through hole for fixing the ear to the set S.

그런데 이러한 종래의 러그(1)는 방폭밴드(B)에 접촉하는 고정부(2)가 평활하게 형성된 구성이므로 이어(3)등이 외부와 접촉될 경우 러그(1)가 방폭밴드(B)에 대해 미끄러지는 문제가 있었다. 이에따라 러그(1)가 음극선관(T)에 대해 틸트 및 로테이션되게 되어 러그높이와 각 러그(1)간의 피치등 음극선관(T)에 대한 상대위치가 변하게 되고, 이는 음극선관(T)의 화상장치에의 장착을 위해 번잡한 수정작업이 요구되는 문제가 있었다.However, the conventional lug 1 has a structure in which the fixing part 2 in contact with the explosion-proof band B is smoothly formed, so that when the ear 3 or the like comes into contact with the outside, the lug 1 is connected to the explosion-proof band B. There was a problem of sliding. Accordingly, the lug 1 is tilted and rotated with respect to the cathode ray tube T, so that the relative position with respect to the cathode ray tube T, such as the lug height and the pitch between each lug 1, is changed, which is an image of the cathode ray tube T. There was a problem that complicated modifications were required for mounting to the device.

본 고안의 목적은 상술한 종래의 문제를 감안하여 외부요인에 의한 러그의 음극선관에 대한 상대위치 변화를 최대한 억제할 수 있는 음극선관의 러그를 제공하는 것이다.An object of the present invention is to provide a lug of a cathode ray tube that can suppress a change in relative position of the lug relative to the cathode ray tube due to external factors in view of the above-described conventional problems.

이와같은 목적을 달성하기 위해 본 고안에 의한 음극선관의 러그는 패널과 방폭밴드간에 개재되는 고정부와, 이의 일단으로부터 연장절곡되어 화상장치에 고정되는 음극선과의 러그에 있어서, 방폭밴드에 접촉하는 고정부의 일측면에 다수의 마찰돌기가 구비되어 구성되는 것을 특징으로 한다.In order to achieve the above object, a lug of a cathode ray tube according to the present invention is a lug of a fixing portion interposed between a panel and an explosion-proof band, and a cathode ray that is bent from one end thereof and fixed to an image device, thereby contacting the explosion-proof band. Characterized in that a plurality of friction projections are provided on one side of the fixing portion.

이에따라 본 고안은, 외부요인에 의한 러그의 방폭밴드에 대한 미꾸럼짐이 최대한 억제되게 되므로 러그를 음극선관의 설정위치에 정확하게 고정유지할 수 있어 음극선관의 생산성 향상등에 기여한다.Accordingly, the present invention, the slip of the explosion-proof band of the lug due to external factors is suppressed as much as possible, so that the lug can be accurately fixed to the set position of the cathode ray tube, thereby contributing to the improvement of the cathode ray tube productivity.

이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제3도 및 제4도에서, 본 고안에 의한 음극선관의 러그(11)는 음극선관(T)의 패널(P) 스커어트(K)와 방폭밴드(B) 사이에 개재되어 지지되는 고정부(12)와, 이 고정부(12)의 일단으로부터 연장되어 화상장치(도시안됨)에 고정되는 이어(13)가 ㄱ형으로 직각 절곡되어 구성된다.3 and 4, the lug 11 of the cathode ray tube according to the present invention is a fixing part interposed between and supported between the panel P skirt of the cathode ray tube T and the explosion-proof band B. (12) and the ear 13 which extends from one end of this fixing part 12 and is fixed to an image device (not shown) are configured to be bent at right angles to an a-shape.

이어(13)에는 러그(11)를 화상장치에 고정하기 위한 관통구멍(13a)이 형성되고, 방폭밴드(B)에 접촉하는 고정부(12)의 일측면에는 본 고안의 특징에 따라 다수의 마찰돌기(14)가 형성된다. 이 마찰돌기(14)는 방폭밴드(B)와의 마찰력을 증가시킬 수만 있으면 어떠한 형태라도 좋으나, 바람직하기로는 도시된 바와같이 엠보싱(embossing) 형태로 구성된다. 또한 배열형태 역시 규칙적으로 또는 무작위로 구성될 수 있으나, 전 접촉면에서의 균일한 접촉을 위해 도시된 바와같이 소정간격의 규칙적으로 구성되는 것이 바람직하다.In the ear 13, a through hole 13a for fixing the lug 11 to the image device is formed, and on one side of the fixing part 12 in contact with the explosion-proof band B, a plurality of The friction protrusion 14 is formed. The friction protrusion 14 may be any shape as long as it can increase the frictional force with the explosion-proof band B, but is preferably configured in the form of embossing as shown. The arrangement may also be configured regularly or randomly, but it is preferred that the arrangement be regularly arranged at predetermined intervals as shown for uniform contact across the entire contact surface.

이와같은 구조적 특징을 가지는 본 고안에 의한 음극선관의 러그(11)는 방폭밴드(B)와 접촉하는 고정부(12)에 다수의 마찰돌기(14)가 형성되어 있으므로 밴딩시 방폭밴드(B)와의 접촉 마찰력이 평활한 종래에 비해 크게 증대된다. 이에따라 이어(13)등이 외부와 접촉되더라도 방폭밴드(B)에 대한 미끄러짐이 최대한 억제되어 음극선관(T)에 대한 틸트나 로테이션 등이 발생되지 않게 된다. 그러므로 러그(11)를 음극선관(T)의 정확한 설정위치에 고정유지 할 수 있다.Lug 11 of the cathode ray tube according to the present invention having such a structural feature has a plurality of friction projections (14) formed in the fixing portion 12 in contact with the explosion-proof band (B) explosion-proof band (B) when bending The contact friction force with is greatly increased as compared with the conventional smooth. Accordingly, even if the ear 13 or the like is in contact with the outside, the slip on the explosion-proof band B is suppressed to the maximum, so that no tilt or rotation of the cathode ray tube T is generated. Therefore, the lug 11 can be fixedly held at the correct setting position of the cathode ray tube T.

이와같이 본 고안에 의하면, 외부요인에 의한 러그의 방폭밴드에 대한 미끄러짐이 최대한 억제되므로 러그를 음극선관의 설정위치에 정확히 고정유지 할 수 있다. 이에따라 본 고안은 음극선관의 화상장치에의 장착시 종래와 같은 별도의 수정작업 등이 불필요하게 되어 음극선관의 생산성 등을 향상시키는 효과가 있다.Thus, according to the present invention, since the slip to the explosion-proof band of the lug due to external factors is suppressed as much as possible, the lug can be accurately held at the set position of the cathode ray tube. Accordingly, the present invention eliminates the need for a separate modification operation as in the prior art when the cathode ray tube is mounted on the image device, thereby improving productivity of the cathode ray tube.
