この発明は、ブラウン管本体の側壁部に帯枠を付設し、
側壁部に締め付は力を加える防爆型ブラウン管に関する
ものである。[Detailed Description of the Invention] [Industrial Field of Application] This invention provides a method for attaching a band frame to the side wall of a cathode ray tube body.
Tightening is related to explosion-proof cathode ray tubes that apply force to the side walls.

の外側に焼きばめによって配設された帯枠である。2 and 3 are diagrams showing an explosion-proof cathode ray tube shown in Japanese Patent Publication No. 54-22864, which has been conventionally used, in which 1 is the cathode ray tube body, 11 is the side wall of the cathode ray tube body 1, and 2 is the side wall portion 1 of the cathode ray tube body 1]
This is a band frame placed on the outside of the frame by shrink fitting.
このように従来のブラウン管本体1の防爆対策としてブ
ラウン管本体1のパネル側壁部11に締め付は用の帯枠
2を焼きばめる、いわゆるシュリンク方式がとられてい
る。As described above, as a conventional explosion-proof measure for the cathode ray tube body 1, a so-called shrink method has been adopted in which a tightening band frame 2 is shrink-fitted to the panel side wall portion 11 of the cathode ray tube body 1.
この従来のブラウン管は、まずパネルの側壁部局長より
やや短く形成した内周長を有する均一な厚さの薄い鋼鉄

壁部11に締め付は力が加わるように構成されている。This conventional cathode ray tube is manufactured by first stretching a thin steel band frame 2 of uniform thickness with an inner circumference slightly shorter than the length of the side wall of the panel by heating and fitting it into the side wall of the cathode ray tube. The structure is such that a tightening force is applied to the panel side wall portion 11 when the frame 3 returns to normal temperature.
この従来の防爆型ブラウン管では、帯枠の締め付は力が
ブラウン管本体の四隅部に集中し、側壁部に及ぼす力が
わずかとなるため、防爆性能を十分に発揮させられない
という1gJ題点があった。In this conventional explosion-proof cathode ray tube, when tightening the band frame, the force is concentrated on the four corners of the cathode ray tube body, and the force exerted on the side walls is small, so there is a 1gJ problem in which the explosion-proof performance cannot be fully demonstrated. there were.
この発明はこのような締め付は力が片寄るという問題点
を除去するためになされたもので、側壁部にも締め付は
力の一部を圧力として与えることにより、防爆性能を向
上した防爆型ブラウン管を得ろことを目的とする。This invention was made in order to eliminate the problem that the force is biased when tightening, and by applying part of the force to the side wall as pressure, it is an explosion-proof type that improves explosion-proof performance. The purpose is to obtain a cathode ray tube.
この発明に係る防爆型ブラウン管は、−面の全面がブラ
ウン管本体の側壁部の形状に合わせて形成された帯枠を
ブラウン管本体の側壁部に焼きばめしたものである。In the explosion-proof cathode ray tube according to the present invention, a band frame whose entire negative surface is formed to match the shape of the side wall of the cathode ray tube body is shrink-fitted to the side wall of the cathode ray tube body.
この発明における帯枠は、全面がブラウン管本体の側壁

管本体の側壁部にも締め付は力が及ぼされろようになり
、防爆性能を向上することができる。Since the band frame according to the present invention is formed so that its entire surface conforms to the shape of the side wall of the cathode ray tube body, the band frame uniformly adheres to the inner peripheral surface of the band frame and the side wall of the cathode ray tube body, and the side wall of the cathode ray tube body Tightening also allows less force to be applied, improving explosion-proof performance.
以下この発明の一実施例を第1図にもとづいて説明する

他の構成は第2図および第3図に示す従来のものと同様
であるので説明を省略する。An embodiment of the present invention will be described below with reference to FIG. That is, in FIG. 1, 3 is formed into an annular shape slightly shorter than the side circumference of the cathode ray tube by joining by appropriate means, and is processed into a shape that conforms to the shape of the side wall 11 of the cathode ray tube body 1. It is a obi frame. Note that the other configurations are the same as the conventional ones shown in FIGS. 2 and 3, so explanations will be omitted.
このように形成された帯枠3を焼きばめによってブラウ

る。Here, when cooling after shrink fitting, the entire band frame contracts as in the conventional case, and tightening force is exerted on the four corners of the cathode ray tube, but in this case, the band frame 3 Because it is processed to conform to the shape of
1 and is configured to apply pressure to the side wall 11 of the cathode ray tube body, improving explosion-proof performance.
なお、この実施例では帯枠の各辺部の形状を加工した場
合について示したが、帯枠の全周を加工してもよい。In this embodiment, the shape of each side of the band frame is processed, but the entire circumference of the band frame may be processed.
