Dielectric filter

Abstract

Abstract PURPOSE:To apply simultaneously grounding and mechanical fixation between a dielectric resonator and a case by using a nearly U-shaped finger. CONSTITUTION:The type of material of the nearly U-shaped finger 13 is made selected as a material such as spring nickel silver because of the necessity of no rust and grounding. As the shape, two side faces 13-4 bent upper outward from both ends of a bottom 13-3 and prescribed number of claws formed by cutting the tip of each side face and prescribed number of tongue piece 13-2 curved inward at the middle are provided. In inserting the nearly U-shaped finger 13 mounted with a dielectric resonator 1 contacts the conductor film of the dielectric resonator 1 to attain grounding. In pressing the finger further from this state, since the claw 13-1 contacts the side face of the package case 2 with the reaction of the tongue 13-2 and the tongue 13-2 contacts the conductor film strongly respectively, the mechanical fixation and grounding are applied at the same time.
