COLLECTOR FOR ELECTRONIC TUBE

PROBLEM TO BE SOLVED: To miniaturize a collector for an electronic tube.SOLUTION: A collector for electronic tube 1 includes: a cylindrical ground electrode 2; and a plurality of collector electrodes 5a and 5b that includes a cylindrical shape, in which an outer peripheral surface is separated from an inner peripheral surface of the cylindrical ground electrode 2, and which is arranged in parallel with a direction of a center axis of the cylindrical ground electrode 2 in the inner part of the cylindrical ground electrode 2. The collector for electronic tube 1 comprises insulation members 11 and 12 arranged between the cylindrical ground electrode 2 and the collector electrodes 5a and 5b. The insulation members 11 and 12 are nipped to a direction orthogonal to the center axis by the cylindrical ground electrode 2 and the plurality of collector electrodes 5a and 5b. The insulation members 11 and 12 are nipped to the direction of the center axis by a flange 8 and a fixed member 9. The insulation members 11 and 12 insulate the cylindrical ground electrode 2 and the collector electrodes 5a and 5b. The insulation members 11 and 12 insulate provide a projection part 14 positioned between the adjacent collector electrodes 5a and 5b, and thus the collector electrode 5a and the collector electrode 5b are insulated.SELECTED DRAWING: Figure 1 【課題】電子管用コレクタを小型化する。【解決手段】電子管用コレクタ１は、筒状の接地電極２、および、筒状の形状を有し、外周面が接地電極２の内周面から離隔して、接地電極２の内部に接地電極２の中心軸の方向に並べて配置される複数のコレクタ電極５ａ，５ｂを備える。電子管用コレクタ１は、接地電極２とコレクタ電極５ａ，５ｂとの間に配置される絶縁部材１１，１２を備える。絶縁部材１１，１２は、接地電極２および複数のコレクタ電極５ａ，５ｂによって、中心軸と直交する方向に挟持される。また絶縁部材１１，１２は、フランジ８および固定部材９によって、中心軸の方向に挟持される。絶縁部材１１，１２は、接地電極２とコレクタ電極５ａ，５ｂのそれぞれとを絶縁する。また絶縁部材１１，１２は、隣接するコレクタ電極５ａ，５ｂの間に位置する、突起部１４を設けることで、コレクタ電極５ａとコレクタ電極５ｂとを絶縁する。【選択図】図１
