Abstract

PURPOSE:To eliminate the need for a conventional resin pin by fixing tentatively a metallic pin while the metallic pin is inserted to a hole in the axial direction, impregnating an uncured resin to the hole and curing the uncured resin. CONSTITUTION:A metallic pin is fixed tentatively while it is inserted to center of throughholes 5a, 5b for an inner conductor of a dielectric resonator unit and resins 10a, 10b are injected to a space in the throughholes 5a, 5b and filled up to the open end face of the dielectric resonator unit 1. A phenol resin or an epoxy resin is used as the injected resin which is liquid in the uncured state and cured by polymerization. Since the resin after curing acts like a conventional resin pin, this method copes with a resin pin formed in advance in response to the shape of the metallic pin or with any size of the metallic pin.

(C1 Problem to be Solved by the Invention In this type of installation in which a metal pin is attached via a resin bottle, multiple types of metal pins with different outer diameters are selected in order to set the coupling capacitance between the metal pin and the inner conductor to a predetermined value. Therefore, it is necessary that the inner diameter of the resin bottle be adjusted accordingly, and as the number of types of metal pins increases, the number of types of resin bottles also increases, leading to an increase in management costs. In addition, in order to increase the coupling capacity with the inner conductor, it is necessary to use a metal pin with a large outer diameter, but this also causes problems such as the resin bottle becoming thinner and difficult to process. Note that these problems are not limited to when attaching metal pins to through holes for forming inner conductors, but also apply when attaching metal pins to coupling holes in multi-stage resonator units. A method for attaching metal pins to a dielectric resonator unit that solves the above-mentioned problems by allowing metal pins of various sizes to be attached to the holes of the dielectric resonator unit without using a bottle. It is about providing.
