にしている。FIG. 5 shows a fixing structure using a spring, in which the dielectric coaxial resonator 2 is stored horizontally in the case 4 and is elastically pressed from above by the holding plate 6 and the spring material 8. 2 is fixed in the axial direction by a fixing rubber 10 and a fixing protrusion (abutment) 401 provided on the case 4.
尚、誘電体同軸共振器２は、筒状（例えば円筒状、角筒

誘電体同軸共振器２も、詳細は図示しないがこれとほぼ
同様の構造をしている。The dielectric coaxial resonator 2 includes an inner conductor 202 formed on the inner circumferential surface of a dielectric material 201 made of ceramic or the like having a cylindrical shape (for example, a cylindrical shape, a rectangular cylindrical shape, etc.), and an outer conductor 203 formed on the outer circumferential surface. ,
One end surface S is an open end surface, and the other end surface is an inner conductor 20.
2 and the outer conductor 203 are short-circuited. The dielectric coaxial resonator 2 in other figures also has a substantially similar structure, although details are not shown.
所がばねによる固定構造では、例えば第６図のように誘

うな場合等では、誘電体同軸共振器２の軸方向に前述し
たような固定用突起４０１を設けられない構造となるこ
とがあり、その場合は誘電体同軸共振器２が動いた時に
短絡等の致命的な故障に陥ってしまう恐れがある。However, with a fixed structure using a spring, if the dielectric coaxial resonator 2 is inserted vertically from above the case 4 as shown in FIG. In some cases, the structure may not be able to provide the fixing protrusion 401, and in that case, when the dielectric coaxial resonator 2 moves, there is a risk of a fatal failure such as a short circuit.
上記不具合を防止するために、例えば第７図に示すよう
に、誘電体同軸共振器２の開放端面Ｓとケース４間に接
着剤１４を塗る手段があるが、これによるとＱｏが誘電
体同軸共振器２単体の場合に比べて悪くなってしまう。In order to prevent the above-mentioned problem, there is a method of applying an adhesive 14 between the open end surface S of the dielectric coaxial resonator 2 and the case 4, as shown in FIG. 7, for example. According to this method, Qo is This is worse than when the resonator 2 is used alone.
一方、例えば第８図に示すように、誘電体同軸共振器２

ングである。On the other hand, as shown in FIG. 8, for example, a dielectric coaxial resonator 2
In the fixing structure in which the outer conductor 203 and the case 11 are soldered with the solder 16, soldering can be said to be more reliable as it can provide a higher fixing force than the above-mentioned fixing with a spring if the conditions are properly managed. This method cannot be used when the case 4 is made of a material that cannot be soldered, such as aluminum die-casting. Note that 18 in FIG. 8 is an input/output pin capacitively coupled to the inner conductor 202 of the dielectric coaxial resonator 2, and 20 is a bushing with a flange for holding the pin.

しかも共振器単体の特性を劣化させることなく固定する
ことができる固定構造を提供することを目的とする。Therefore, the present invention aims to stably and reliably attach dielectric coaxial resonators to fixed members that cannot be soldered.
Moreover, it is an object of the present invention to provide a fixing structure that can fix a single resonator without degrading its characteristics.

However, a conductive adhesive may be used instead of soldering (the same applies to the following embodiments). Then, the fixing plate 24 to which the dielectric coaxial resonator 2 is fixed is housed in a case 4 (however, the figure shows only a part of the case 4, and the same applies hereinafter), which has a correspondingly shaped part. In this example, each dielectric coaxial resonator 2 and case 4 are
This ensures that the ground (that is, the electrical connection) is securely connected to the terminal, and that it can be semi-fixed. Then, attach the fixing plate 24 to the case 4.
For example, the screws 26 are used to fasten the screws. As a result, each dielectric coaxial resonator 2 is completely fixed to the case 4.

あるいは第１図の例のようなく字状のいずれでも良い。FIG. 2 shows an example of a duplexer using two rows of a plurality of dielectric coaxial resonators 2, in which one fixed plate 24 is used.
The dielectric coaxial resonators 2 in one row (for example, the transmitting side) and the dielectric coaxial resonators 2 in the other row (for example, the receiving side) can be fixed to the case 4 at the same time. . That is, the left and right sides of the fixing plate 24 are bent to correspond to the series of dielectric coaxial resonators 2, and the dielectric coaxial resonators 2 are soldered thereto, and the fixing plate 24 is shaped to correspond to the bending. Case 4 with parts
It is fixed with screws 26. In addition, the fixed plate 24
The spring portion 241 provided in this example has a flat plate shape,
Alternatively, it may be dogleg-shaped as in the example shown in FIG.

するようにしている。FIG. 3 shows an example of a filter using a plurality of cylindrical dielectric coaxial resonators 2, in which the fixing plate 24 is bent and raised at intervals corresponding to the outer diameter dimension of the dielectric coaxial resonators 2 to form a plurality of partitions. Each dielectric coaxial resonator 2 is sandwiched between the two partition parts 242 and soldered so that it can be handled in the same way as an integral part, thereby making the fixing work easier. There is. In this example, the fixing plate 24 is placed over the case 4 and fixed with screws 26.
尚、固定板２４のケース４への固定手段としては、上記
例のようなねじ止めの他に、例えばリベット止め、ケー

突起４０２を有するケース４内に収納して、固定板２４
の端部２４３をかしめることによって固定するようにし
ている。As a means for fixing the fixing plate 24 to the case 4, in addition to screwing as in the above example, means such as riveting, caulking of the case 4, caulking of the fixing plate 24, etc. can be used. For example, in the example shown in FIG. 4, the fixing plate 24 to which the dielectric coaxial resonator 2 is soldered (16 indicates solder) is housed in a case 4 having protrusions 402 for caulking, and the fixing plate 24 is
It is fixed by caulking the end portion 243 of.
上記各固定構造によれば、ケース４内で誘電体同軸共振
器２が動く恐れはなく極めて安定した固定が可能である
。According to each of the fixing structures described above, there is no fear that the dielectric coaxial resonator 2 will move within the case 4, and extremely stable fixation is possible.
しかも、第７図の場合のように誘電体同軸共振器２の開
放端面Ｓに接着剤１４を塗るような必要も無いので、誘
電体同軸共振器２単体の特性を劣化させることも無い。Moreover, since there is no need to apply adhesive 14 to the open end surface S of the dielectric coaxial resonator 2 as in the case of FIG. 7, the characteristics of the dielectric coaxial resonator 2 alone are not deteriorated.
また、誘電体同軸共振器２の固定板２４への固定に半田
付けを採用した場合、これを従来の例えば第６図の場合
のようなばね材８による固定と比較すると、ばねの場合

の固定力が限界であるのに対して、半田付けは５０ｋｇ
ｆ程度も取れるのでくいずれも例えば同寸法の小形股間
フィルタで比較した場合）、機械的強度が大きく信頼性
も高くなる。Furthermore, when soldering is used to fix the dielectric coaxial resonator 2 to the fixing plate 24, comparing it with conventional fixing using a spring material 8 as shown in FIG. The fixing force is limited to about 10 to 20 kgf due to the elasticity of the material, etc., whereas the fixing force for soldering is 50 kg.
For example, when compared with a small crotch filter of the same size, the mechanical strength is high and the reliability is high.
更に、ケース４に直接半田付けをする必要が無いので、
ケース４の材料としては、例えば鋼、銅合金、アルミダ
イカスト、あるいはプラスチック等の種々のものが採り
得る。特に、アルミダイカストは、軽量、堅牢かつ電気

用することもでき、それよって所期のフィルタ特性を確
実に得ることができる。Furthermore, since there is no need to solder directly to case 4,
The case 4 can be made of various materials, such as steel, copper alloy, aluminum die-casting, or plastic. In particular, although aluminum die-casting is lightweight, strong, and has excellent electrical shielding properties, it has the disadvantage that it cannot be directly soldered. However, according to the fixing structure of this example, such aluminum die-casting can be used as a case material. It is also possible to adopt this method, thereby ensuring that the desired filter characteristics can be obtained.
