FIG. 1A is a top view with a cover removed, and FIG. 1B is a vertical cross-sectional view seen from the front. In FIG. 1, 1 is a metal case body, and 2 is a metal cover that covers the upper part of the case body 1 in the figure. The case body 1 and the cover 2 form a shield case according to the present invention. Inside the case main body 1, a dielectric resonator 3 made of a cylindrical dielectric ceramics is disposed via a support base 4 made of a low dielectric constant cylindrical or cylindrical ceramics. Case body 1 and support 4
And the support base 4 and the dielectric resonator 3 are bonded and fixed by an adhesive. Signal input / output connectors 5a and 5b are fixed by screws on the left and right sides of the case body 1 in the figure. The case main body 1 is provided with holes through which the center conductors 6a and 6b of the connectors 5a and 5b are inserted on the left and right sides, and when the connectors 5a and 5b are attached to the case main body 1, the center conductors 6a and 6b are It projects into the case. One ends of elastic metal plates 7a and 7b are connected and fixed to the center conductors 6a and 6b of these connectors by soldering or the like. This metal plate 7

A screw hole is provided in the front-rear direction of the case body 1 in the figure, and insulative screw members 8a and 8b made of synthetic resin or ceramics are screwed together. The tips of the screw members 8a and 8b in the case are brought into contact with the vicinity of the other ends of the metal plates 7a and 7b. Here, the metal plates 7a and 7b have one ends connected and fixed to the center conductors 6a and 6b of the connector, respectively, and the other ends are in contact with the screw members 8a and 8b. However, due to the action of the elastic force,

Therefore, for example, if the screw member 8a is rotated to increase the protruding amount of the screw member 8a into the case, the metal plate is deformed as shown by 7a ', and the metal plate 7a' is shown.
When the screw member 8a is rotated in the opposite direction, the metal plate 7a is deformed in a direction away from the dielectric resonator 3. This also applies to the relationship between the screw member 8b and the metal plate 7b.

Unlike the dielectric resonator device shown in FIG. 1A as the first embodiment, this dielectric resonator device uses metal screw members as the screw members 9a and 9b. Other configurations are the same as those in the first embodiment.

Magnetic fields are coupled to the two coupling loops. Therefore, for example, if the screw member 9a is rotated to increase the protruding amount of the screw member 9a into the case, the metal plate is deformed as shown by 7a ', and the metal plate 7a', the screw member 9a, and the case body 1 are separated. As the distance between the coupling loop formed by the inner wall surface and the dielectric resonator 3 approaches, the loop area of the coupling loop increases,
The bond becomes stronger. Rotate the screw member 9a in the opposite direction,
If the amount of protrusion of the screw member 9a into the case is reduced, the distance between the dielectric plate 3 and the coupling loop formed by the metal plate 7a ', the screw member 9a and the inner wall surface of the case body 1 is increased, and the loop of the coupling loop is increased. The area is reduced and the bond is weak. This also applies to the case where the metal plate 7b is deformed by the screw member 9b.

A dielectric resonator is provided in a shield case, a signal input / output connector is attached to the case, and a central conductor of the connector is projected into the case, so that the elastic member is made of one of metal materials having elasticity. The end portion is connected and fixed to the central conductor of the connector in the case, and the tip end portion is brought into contact with the vicinity of the other end portion of the metal material, and the amount of protrusion into the case is changed by rotation. A dielectric resonator device in which a screw member is screwed into the case.
