る。 Insertion holes 10 are formed in the side wall 9 of the metal frame 2 at equal intervals with the trimmer plate portion 6 of the metal plate 1. When the trimmer plate portions 6 of the metal plate 1 are firmly fitted from the insertion holes 10 toward the inside of the metal frame 2, the tongue pieces 8 are elastically deformed when passing through the insertion holes 10, and are deformed by restoring force after passing through the insertion holes 10. Returning to the original state, the metal plate 1 is attached to the side wall 9 with the tip of the tongue piece 8 in contact with the inner surface of the side wall 9 and the inner surface of the base 7 with the outer surface of the side wall 9, as shown in FIG. After installation, the metal plate 1 is firmly fixed to the side wall 9 of the metal frame 2 by soldering or the like (not shown).

In Fig. 2, each stage divided by the shield plate 4' is an OSC stage, a MIX stage, an RF amplification stage, and an RF amplification stage from the right.
The ANT input stage is shown, and the tuning frequency is optimally adjusted by bending and deforming the trimmer plate part 6 of each stage and adjusting the distance between each trimmer plate part 6 and the center conductor 3. It will be done.

UHFチユーナを提供することができる。 Since the present invention is structured as described above,
For example, to configure a trimmer capacitor, a printed conductor connected to an inductor (center conductor) is not required, and the corresponding space and alternative configurations are also unnecessary, allowing for space saving and miniaturization. Also,
Since the distance between the trimmer plate and the center conductor is adjusted by bending the trimmer plate, for example, if the trimmer plate is twisted, the effect of springback cannot be ignored, which limits the materials that can be used. However, it may be made of mild steel, for example, and restrictions on the materials to be used can be reduced. In addition, multiple trimmer plate sections can be attached in one step, and the number of parts can be reduced, reducing costs and improving workability. Also, since the trimmer plate is fixed to the metal frame, howling due to vibration is less likely to occur.
Can provide UHF tuner.
