。A conventional magnetron output section is, for example, disclosed in Japanese Patent Application Laid-open No. 61-20
As described in Japanese Patent No. 6135, the joint between the exhaust pipe that seals the end of the output output antenna and the cup body that hermetically seals the interior of the cavity resonator is fixed with silver solder.
従来のマグネトロン出力部は、排気管とカップ体とのろ
う付は部に配置される銀ろうの加熱による変形に関して
は全く配慮されておらず、銀ろうの不要部への流れ出し
、ひいてはろう付は不良を招くなどの問題があった。In the conventional magnetron output section, no consideration was given to the deformation of the silver solder placed in the brazing section between the exhaust pipe and the cup body due to heating, and the silver solder could flow out to unnecessary parts and eventually the brazing There were problems such as causing defects.
本発明は前述した従来の問題に鑑みてなされたものであ

へのろう材の流れを確実にしてろう付は不良を防止し、
ろう材の節約を可能としたマグネトロン出力部を提供す
ることにある。The present invention was made in view of the above-mentioned conventional problems, and its purpose is to prevent deformation of silver solder and ensure the flow of brazing material to the joint surface to prevent defects in brazing. ,
An object of the present invention is to provide a magnetron output section that enables saving of brazing material.
本発明によるマグネトロン出力部は、排気管とカップ体
との接合部に銀ろうの収納可能な段差部を設けたもので
ある。The magnetron output section according to the present invention is provided with a stepped portion in which silver solder can be stored at the joint between the exhaust pipe and the cup body.

マイクロ波を導出するアンテナ１の他端部側は排気管２
に封止切り切断されている。An embodiment of the present invention will be explained below with reference to FIG. In the figure, the other end of the antenna 1 is connected at one end to a cavity resonator (not shown) and derives microwaves from an exhaust pipe 2.
It has been sealed and cut.
また、この排気管２の外周部には、カップ体３がその端

う材料そのものも無駄な部分が発生し、コストメリット
を失なうので、本実施例の構造が極めて有効となる。In such a configuration, a wire-shaped silver brazing material was wound and cut as shown in FIG. Silver wax 5
When the cut portion 5& is inserted and heated, a phenomenon occurs in which the cut portion 5& is expanded as shown by the dotted line in the figure. Therefore, if the conventional structure does not have the stepped portion 3a of the cup body 3, the amount of melted silver solder 5 that goes around the joint surface between the exhaust pipe 2 and the cup body 3 will be reduced, and will flow out to unnecessary parts, causing This leads to poor brazing. On the other hand, in this embodiment, since the stepped portion 3a of the cup body 3 prevents the silver solder from spreading as described above, a sufficient amount of silver solder 5 can be supplied to the joint. In addition, if the silver solder 5 is punched out of a sheet material and formed, the expansion of the silver solder itself can be further prevented, but the silver solder material itself will have a wasted portion, and the cost advantage will be lost. The structure of this embodiment is extremely effective.

奏する。As explained above, according to the present invention, a stepped portion is provided in the part of the cup body where the exhaust pipe is inserted and joined, and the silver solder is stored in the stepped portion, and the soldering is performed by joining. It is possible to use wax molded from inexpensive wire material,
Moreover, since the brazing material can be efficiently supplied to the joint, the required amount of the brazing material itself can be reduced, resulting in great industrial effects.
