본 고안은 음극선관의 방폭밴드에 관한 것으로서, 특히 인장강도가 크게 향상됨과 아울러 러그가 용접에 의하지 않고도 부착될 수 있도록 한 것에 관한 것이다.The present invention relates to an explosion-proof band of a cathode ray tube, and more particularly, to the tensile strength is greatly improved and to allow the lug to be attached without welding.

일반적으로 음극선관용 방폭밴드(20)는 제3도에 도시된 바와같이 일정두께의 편상몸체로 되어 그 모서리부에 음극선관 고정용 리그(30)가 용접에 의해 부착되어지는 것으로서, 음극선관이 대형화되어 감에 따라 상기몸체의 두께를 두껍게 하여 그 인장강도를 향상시켜야 할 필요가 있는 것이다, 뿐만 아니라 밴드의 모서리부의 러그(30)가 상기한 바와 같이 용접에 의해 부착되기 때문에 그 용접부위에 재질변화에 따른 녹이 발생되는바, 이는 밴드(20)의 재질을 약하게 하는 것으로서 이를 개선할 필요가 있는 것이다.In general, the explosion-proof band 20 for the cathode ray tube is a flake body having a predetermined thickness as shown in FIG. 3, and the cathode ray tube fixing rig 30 is attached to the corner portion by welding, and the cathode ray tube is enlarged. As the thickness of the body increases, it is necessary to increase its tensile strength, as well as the lugs 30 of the edges of the band are attached by welding as described above. According to the rust is generated, which is to weaken the material of the band 20 is necessary to improve this.

따라서 본 고안은 그 인장강도가 크게 향상됨과 아울러 러그와의 용착부위가 제거됨으로써 )( 의한 취약부위가 발생되지 않도록 형성된 것을 특징으로 하는 음극선관용 방폭밴드를 제공함에 그 목적이 있는 것이다.Therefore, the present invention is to provide an explosion-proof band for cathode ray tubes, characterized in that the tensile strength is greatly improved and the welded portion with the lug is removed so as to prevent the fragile portion from occurring.

상기의 목적을 달성하기 위하여 본 고안의 일정폭의 판재가 겹쳐진 채 U형으로 절곡됨으로써 내측밴드와 외측밴드로 그 몸체가 형성되고, 그 몸체의 네모서리에 설치되는 러그는 상기 몸체사이, 즉내측밴드와 외측밴드 사이에 개재되어 상기 내, 외측밴드의 밀착력으로써 고정되도록 한 점에 특징이 있다.In order to achieve the above object, a certain width of the plate of the present invention is overlapped and bent in a U-shape to form a body with an inner band and an outer band, and the lugs installed at the four corners of the body are between the bodies, that is, the inner side. It is characterized by being interposed between the band and the outer band to be fixed by the adhesion of the inner and outer bands.

이하 첨부된 도면을 통하여 본 고안을 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제1도에 도시된 바와같이 음극선관의 패널(10) 외주면에 밀착고정되어 있는 방폭밴드(20)는 일정폭의 판재가 겹쳐진 채 U형으로 밴딩형성된 것으로서 이에 의해 두겹의 밴드 즉, 한몸을 이루는 내측밴드(22)와 외측밴드(21)로 이루어진다. 그리고 모서리에 설치되는 러그(30)는 상기 밴드의 틈사이 즉, 내측밴드(22)와 외측밴드(21)사이에 개재된채 밀착고정된다. 여기에서 상기 러그(30)에는 제2도에 도시된 바와 같이 L형의 몸체 양측에 관통공(31)(32)이 각각 형성되어서 그중에 외부에 노출되는 부위의 관통공(31)은 체결부품이 끼워지는 부위이고, 상기 밴드(21)(22)사이에 끼워진 부위의 관통공(32)은 러그의 결합상태를 강화시키기 위한 요소인 것이다.As shown in FIG. 1, the explosion-proof band 20 fixed to the outer circumferential surface of the cathode ray tube 10 is banded into a U-shape with overlapping plates of a predetermined width, thereby forming two bands, that is, one body. It consists of an inner band 22 and an outer band 21. And the lug 30 is installed at the corner is tightly fixed while interposed between the gap of the band, that is, between the inner band 22 and the outer band 21. Here, the lug 30 has through holes 31 and 32 formed on both sides of the L-shaped body, as shown in FIG. 2, so that the through holes 31 of the portions exposed to the outside are fastened parts. The insertion part, the through-hole 32 of the part sandwiched between the band 21, 22 is an element for reinforcing the coupling state of the lug.

즉 상기 러그(30)의 일측부가 내외측밴드(21)(22)사이에 밀착고정된 상태에서 내측관통공(32)과 마주대하는 외측밴드(21)이 모서리 부위에 둥근요홈(23)을 상기 관통공(32) 내측으로 용출되도록 펀칭 형성함으로써 상기 러그(30)가 상기 내외측 밴드(21)(22)의 밀착력에 의해서 뿐만 아니라 상기 둥근요홈(23)의 체결력에 의해서도 고정된다.That is, the outer side band 21 facing the inner through hole 32 in a state where one side of the lug 30 is tightly fixed between the inner and outer bands 21 and 22 and the round groove 23 is formed at the corner. By forming punching so as to elute into the through hole 32, the lug 30 is fixed not only by the adhesion of the inner and outer bands 21 and 22, but also by the fastening force of the round groove 23.

이와 같이 본 고안은 두겹으로 형성된 몸체를 갖기 때문에 그의 인장강도가 크게 향상됨과 아울러 그 모서리에 부착되는 러그가 용접에 의하지 않고도 강한 파지력으로서 고정된다. 따라서 인장강도의 강화로 음극선관의 안전성이 크게 향상됨과 아울러 용접부위가 없기 때문에 재질변화에 따른 부식부위가 발생되지 않는다.Thus, since the present invention has a body formed in two layers, the tensile strength thereof is greatly improved, and the lugs attached to the corners thereof are fixed as a strong gripping force without welding. Therefore, the safety of cathode ray tube is greatly improved by the strengthening of tensile strength, and there is no welding part, so no corrosion part occurs due to material change.

이러한 방폭밴드는 대형의 음극선관에 적합한 것으로서, 종래의 것보다 제작이 용이하고 외관이 단정한 한편 녹에 의한 강도저해요인이 근본적으로 해소된 실용적인 고안품인 것이다.Such an explosion-proof band is suitable for large cathode ray tubes, and is a practical design that is easier to manufacture than the conventional one, and the appearance is neat, and the strength deterioration caused by rust is fundamentally eliminated.
