Description
【考案の詳細な説明】 本考案は陰極線管の電子銃に関するものである。[Detailed explanation of the idea] The present invention relates to an electron gun for a cathode ray tube.
一般に陰極線管の電子銃は、カンードと、ヒータと、ヒ
ータを保持するヒータサポートを合し、ヒータはヒータ
サポートより電力を供給されて発熱し、これによりカン
ードは加熱されて電子ビームを放射するようになってい
る。In general, a cathode ray tube electron gun combines a cando, a heater, and a heater support that holds the heater.The heater is supplied with power from the heater support and generates heat, which heats the cando and causes it to emit an electron beam. It has become.
第１図は従来の電子銃のヒータサポート部を示す。FIG. 1 shows a heater support section of a conventional electron gun.
即ち、マルチフオームガラス１にヒータリードストラッ
プ２が保持固定され、このヒータリードストラップ２に
赤ヒータ３、録ヒータ４、青ヒータ５が溶接されたヒー
タサポート６が溶接点７で溶接固定されている。That is, a heater lead strap 2 is held and fixed to the multiform glass 1, and a heater support 6 to which a red heater 3, a recording heater 4, and a blue heater 5 are welded is welded and fixed to the heater lead strap 2 at a welding point 7. .
このようにヒータサポート６は１個のヒータリードスト
ラップ２で支持でれているため、両端の赤ヒータ３、青
ヒータ５が非常に賑動しやすい構造となっている。Since the heater support 6 is supported by one heater lead strap 2 in this way, the structure is such that the red heater 3 and the blue heater 5 at both ends are very likely to vibrate.
そこで、電子銃製作工程中の取扱いによってヒータサポ
ート６に医動が加辷られると、ヒータ３，５が新組する
おそれがあるため、細心の注意を払って取拙う必要があ
った。Therefore, if the heater support 6 is subjected to medical action during handling during the electron gun manufacturing process, there is a risk that the heaters 3 and 5 will be reassembled, so it was necessary to handle the electron gun with great care.
本考案は上記従来製品の欠点に鑑みなされたもので、ヒ
ータ断線がなく作業能率および品質の向上をはかり得る
陰極線管の電子銃を提供することを目的とする。The present invention was devised in view of the above-mentioned drawbacks of conventional products, and it is an object of the present invention to provide a cathode ray tube electron gun that does not cause heater disconnection and can improve work efficiency and quality.
以下本考案を図示の実施例に基づき説明する。The present invention will be explained below based on the illustrated embodiments.
第２図は本考案になる電子部の要部を示す。FIG. 2 shows the main parts of the electronic section according to the present invention.
マルチフオームガラス１には２個のヒータリードストラ
ップ２１．２２が固定されており、これら２佃のヒータ
リードストラップ２１．２２”）ヒータサポート固定面
２１ａ、２２ａはそれぞれ外方にｆがって傾斜している
。Two heater lead straps 21, 22 are fixed to the multiform glass 1, and the heater support fixing surfaces 21a, 22a of these two heater lead straps 21, 22'' are tilted outward. are doing.
またヒータサポート６１は第３図にその側面を示すよう
にヒータ３． ４． ５の固定されるヒータ固定面６１
ａと、このヒータ固定面６１ａに対して山形形状をなし
前記ヒータリードストラップ２１．２２のヒータサポー

ラップ固定面６１ｂ、６１ｂを形成してなる。Further, the heater support 61 is connected to the heater 3. as shown in the side view in FIG. 4. 5 fixed heater fixing surface 61
a, and heater lead strap fixing surfaces 61b, 61b which are chevron-shaped with respect to the heater fixing surface 61a and are fixed to the heater support fixing surfaces 21a, 22a of the heater lead straps 21.22.
このようにヒータサポート６１は２個のヒータリードス
トラップ２１．２２に保持固定してなるので、そ保持は
強固であり、ヒータ３． ４． ５力医動しにくい。In this way, since the heater support 61 is held and fixed to the two heater lead straps 21 and 22, the holding is strong, and the heater 3. 4. 5 Forces It is difficult to move medically.
このことは第４図に示す実験結果によっても裏付ゆられ
る。This is also supported by the experimental results shown in FIG.
第４図はマルチフオームガラス１に賑動を加えた場合の
ヒータサポート６および６１の転動量を測定した゛もの
で、Ａは従来のヒータサポート６の特性を、Ｂは本考案
になるヒータサポート６１の特性をそれぞれ示す。Figure 4 shows the measurement of the amount of rolling of the heater supports 6 and 61 when vibration is applied to the multiform glass 1. A shows the characteristics of the conventional heater support 6, and B shows the characteristics of the heater support of the present invention. 61 characteristics are shown respectively.
図より明らかな如く、本考案になる電子銃のヒータサポ
ート６１の特性はほぼ直線的で殆んど帳動は生じなかっ
た。As is clear from the figure, the characteristics of the heater support 61 of the electron gun according to the present invention were almost linear, and almost no movement occurred.
またヒータリードストラップ２１．２２は外方に広カっ
ており、またヒータサポート６１は山形形状をしている
ため、両方の固定面２１ａと６１ｂおよび２２ａと６１
ｂの位置合せが極めて容易に行なえる。Furthermore, since the heater lead straps 21 and 22 are wide outward and the heater support 61 has a chevron shape, both fixing surfaces 21a and 61b and 22a and 61
The alignment of b can be performed extremely easily.
またヒータサポート６１はほぼ三角形状となるために面
積も少なく熱容量的にも優れている。Furthermore, since the heater support 61 has a substantially triangular shape, it has a small area and is excellent in heat capacity.
さらに、ヒータリードストラップ固定面６１ｂ、６１ｂ
の下端とヒータ固的面６１ａとの隙間６１ｃをある程度
大かくとっても強度的に影響はないので、この隙間６１
ｃよりヒータ３，４゜５を溶接する溶接棒を楽に挿入し
て作業することができる。Furthermore, heater lead strap fixing surfaces 61b, 61b
Even if the gap 61c between the lower end of the
The welding rod for welding the heaters 3, 4 and 5 can be easily inserted and worked from c.
以上の説明から明らかな如く、本考案になる陰極線管の
電子銃によれば、ヒータの転動は非常に小さくヒータ断
線は完全に防出されるので、従来の如く細心の注意をも
って作業する必要がなく、作業能率および品質向上がは
かれる。As is clear from the above explanation, according to the cathode ray tube electron gun of the present invention, the rolling of the heater is very small and heater breakage is completely prevented, so it is not necessary to work with extreme caution as in the conventional case. This improves work efficiency and quality.
