PURPOSE:To facilitate the connection of a resonator to an earth of an outer conductor by cutting and raising a part of a metallic case whose shield plate is conded conductively to form a spring piece and pressing the piece to the outer conductor of a dielectric coaxial resonator. CONSTITUTION:The metallic case 51 is formed with spring pieces 58a, 58b and 59a, 59b... formed by cutting and raising side plates 51a, 51b obliquely inward opposed to each outer conductor 3 of resonators 1-1, 1-2, 1-3 and 1-4. Thin shield plates 63a, 63b are bonded conductively to the side plates 51a, 51b of the metallic case 51 in order to prevent the leakage of an electromagnetic wave from an opening formed by the spring pieces 58a, 59a and the spring pieces 58b, 59b. |
