FINE CAPACITY ADJUSTING DEVICE FOR HIGH FREQUENCY APPARATUS

摘要

PURPOSE:To reduce the number of parts and to obtain a highly reliable adjusting function by using a part of a frame partition plate to constitute a trimmer plate for finely adjusting the capacity of a high frequency apparatus. CONSTITUTION:A holding part 7 is raised from the power side 2a of a partition plate or a shield plate 2 arranged rectangularly to a line and bent at an almost right angle to obtain a fine capacity adjusting structure. The U-shaped trimmer plate 8 having the same shape as the line 5 is opposed to the line 5 almost in parallel from a position opposed to the lower side of the line 5. The tip part of the trimmer plate 8 is rectangularly bent again and inserted into a groove 3a of the partition plate 3 and the holding part 9 rectangularly bent in again the left direction of the trimmer plate 8 is electrically and mechanically connected to the partition plate 3 by soldering or the like. Consequently, the trimmer plate 8 constituted by said procedure can be prevented from basic crack or damage in spite of the execution of severe capacity adjusting work.
