Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、進行波管などの低電位型コレクタの製造方
法に関する。Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a low potential collector such as a traveling wave tube.
進行波管には、電子ビームを捕捉するコレクタに負電
圧を印加する低電位コレクタ方式を採るものが多い。Many traveling wave tubes adopt a low potential collector system in which a negative voltage is applied to a collector that captures an electron beam.
この場合、コレクタの電極部を他の部分と絶縁しなけ
ればならず、また、電極部は電子の衝突により発熱する
ため、冷却効率をよくしなければならない。In this case, the electrode portion of the collector must be insulated from other portions, and the electrode portion generates heat by collision of electrons, so that the cooling efficiency must be improved.
この目的実現のため、通常、電極部と外殻部の間にそ
れぞれの面に密着する熱伝導性の優れた絶縁体を挾み、
外殻部に冷却フインなどを取付ける構造を採る。In order to achieve this purpose, an insulator with excellent thermal conductivity is usually sandwiched between the electrode and the outer shell,
A structure to attach a cooling fin to the outer shell is adopted.
そして、電極部の回転方向のずれをなくするために、
複数個の棒状絶縁体を電極部の外周面と外殻部の内周面
に設けた溝に嵌合、密着させる構造を採ることが多い。And, in order to eliminate the deviation of the rotation direction of the electrode part,
In many cases, a structure is employed in which a plurality of rod-shaped insulators are fitted and closely attached to grooves provided on the outer peripheral surface of the electrode portion and the inner peripheral surface of the outer shell portion.
従来、この種構造の低電位型コレクタの製造では、電
極部と外殻部をそれぞれ１つの素材から製造する方法が
採られてきた。Conventionally, in manufacturing a low-potential type collector having this kind of structure, a method has been adopted in which the electrode portion and the outer shell portion are each manufactured from one material.
すなわち、電極部を、１つの素材に溝用の穴をあけ外
周部を所定の寸法に削り取って製作し、外殻部を、１つ
の素材に溝用の穴をあけ内周部を所定の寸法に削り取っ
て製作し、製作した電極部と外殻部の任意のものを対に
して組合せる方法が採られてきた。That is, the electrode portion is manufactured by drilling a hole for a groove in one material and cutting the outer peripheral portion to a predetermined size, and forming the outer shell portion by drilling a hole for a groove in one material and the inner peripheral portion having a predetermined size. A method has been adopted in which the electrode portion and the shell portion are assembled in arbitrary pairs.
従来の上記方法では、加工寸法の誤差などにより、対
にして組合わせる電極部と外殻部の相対向する溝の相対
位置がずれていて、棒状絶縁体と溝の壁面の密着性が悪
く、所期の冷却効果が得られなかったり、極端なずれの
ため、棒状絶縁体が挿入できなくなるという問題があっ
た。In the conventional method described above, the relative positions of the opposing grooves of the electrode portion and the outer shell portion that are combined in a pair are shifted due to an error in the processing dimension, and the adhesion between the rod-shaped insulator and the wall surface of the groove is poor. There has been a problem that the desired cooling effect cannot be obtained or the rod-shaped insulator cannot be inserted due to an extreme displacement.
また、電極部と外殻部を、それぞれ別個に、１つの素
材の外周部または内周部を相当な量削り取って製作する
ので、素材の無駄になる部分が大きいという問題があっ
た。In addition, since the electrode portion and the outer shell portion are separately manufactured by cutting off the outer peripheral portion or the inner peripheral portion of one material by a considerable amount, there is a problem that a wasteful portion of the material is large.
本発明は、上記の問題を解消するためになされたもの
で、素材の無駄をなくするとともに、棒状絶縁体が嵌合
する電極部と外殻部の溝の相対位置を精度よく確保でき
る方法を提供することを目的とする。The present invention has been made in order to solve the above-described problem, and it is a method of eliminating waste of a material and accurately securing a relative position of a groove of an electrode portion and an outer shell portion in which a rod-shaped insulator is fitted. The purpose is to provide.

す印を付し、内側部分の外周部と外側部分の内周部を所
定の寸法に削り取って電極部と外殻部を製作し、この電
極部と外殻部を対にして組合わせるものである。In order to achieve the above object, the method according to the present invention is characterized in that the center of each material is located on a circumference having a diameter equal to the sum of the outer diameter of the electrode portion and the outer diameter of the rod-shaped insulator. A hole (groove hole) into which a rod-shaped insulator perpendicular to the surface is fitted, and cut the material into an inner portion and an outer portion along the circumference and perpendicular to the surface of the circumference; Are marked to indicate the relative positions to each other, and the outer peripheral portion of the inner portion and the inner peripheral portion of the outer portion are cut to predetermined dimensions to produce an electrode portion and an outer shell portion.

The electrode portion 2 is fixed by fitting and closely fitting the groove on the outer peripheral surface of the above and the groove on the inner peripheral surface of the outer shell portion 3 (FIG. 3).
