This invention relates to a variable tuning resonator that changes the tuning frequency by changing the length of the resonator.

図２は従来の可変同調共振器の１例の構成を示す断面図である。円筒形状のシ ャーシ１の軸案内部１ａには中空軸５が軸受４により枢支されており、この中空 軸５の先端には、めねじ５Ａが設けられている。筒状中心導体６内部にはおねじ ７が設けてあり、中空軸５のめねじ５Ａと螺合している。 FIG. 2 is a cross-sectional view showing the configuration of an example of a conventional variable tuning resonator. Cylindrical shape A hollow shaft 5 is pivotally supported in the shaft guide portion 1a of the chassis 1 by a bearing 4. A female thread 5A is provided at the tip of the shaft 5. There is a male screw inside the cylindrical center conductor 6. 7 is provided and is screwed into the female thread 5A of the hollow shaft 5.
【０００３】 このような構成の従来例において今、中空軸５を回転させることにより中空軸 ５のめねじ５Ａによりこれにおねじ７を螺合した筒状中心導体６がシャーシ１の 円筒形状をした軸案内部１ａに沿って軸方向に摺動する。収縮時においては、筒 状中心導体６は中空軸５と軸案内部１ａ間に挿入され筒状中心導体６のおねじ７ は中空軸５に挿入される。そしてシャーシ１の導体である軸案内部１ａと筒状中 心導体６の長さを可変することにより周波数を変化させている。0003 In the conventional example of such a configuration, by rotating the hollow shaft 5, the hollow shaft The cylindrical center conductor 6 with the screw 7 screwed into it by the female screw 5A of No. 5 is attached to the chassis 1. It slides in the axial direction along a cylindrical shaft guide portion 1a. During contraction, the cylinder The central conductor 6 is inserted between the hollow shaft 5 and the shaft guide portion 1a, and the male thread 7 of the cylindrical central conductor 6 is inserted between the hollow shaft 5 and the shaft guide portion 1a. is inserted into the hollow shaft 5. Then, the shaft guide portion 1a, which is the conductor of the chassis 1, and the cylindrical center The frequency is changed by varying the length of the heart conductor 6.

上記従来例にあっては、 筒状中心導体６内部におねじ７及び中空軸５が挿入されるだけのスペースが 必要であり、筒状中心導体６の外径ｘが大きくなる。 筒状中心導体６の外径ｘとシャーシ１の内径ｙとは、電気的特性を得るため、 ある一定比率を保つ必要があり、筒状中心導体６の外径ｘが大きくなれば必然的 にシャーシ１の外径が大きくなるため、装置を小型化できない。 In the above conventional example, There is enough space inside the cylindrical center conductor 6 to insert the screw 7 and the hollow shaft 5. This is necessary, and the outer diameter x of the cylindrical central conductor 6 increases. In order to obtain electrical characteristics, the outer diameter x of the cylindrical center conductor 6 and the inner diameter y of the chassis 1 are set as follows. It is necessary to maintain a certain ratio, and this becomes inevitable as the outer diameter x of the cylindrical center conductor 6 increases. However, since the outer diameter of the chassis 1 becomes large, the device cannot be miniaturized.
【０００５】 筒状中心導体６が大きく、重量がかさめば、筒状中心導体６が伸長状態では 、構造的に片持ちとなるため、耐振性に乏しく、使用条件が限定される。[0005] If the cylindrical center conductor 6 is large and heavy, the cylindrical center conductor 6 may be in an extended state. Since it is structurally cantilevered, it has poor vibration resistance and its usage conditions are limited.
【０００６】 従来の構造において耐振性を得るには筒状中心導体６を支えているシャーシ １の軸案内部１ａ及びその付け根部１ｂの強度を高める必要があり、重量増加に つながる。[0006] In order to obtain vibration resistance in the conventional structure, the chassis supporting the cylindrical center conductor 6 It is necessary to increase the strength of the shaft guide part 1a and its base part 1b, which increases the weight. Connect.
【０００７】 構造が複雑なため部品点数が多くなり、組立に多大な時間を必要とすると共 にコスト高となる。[0007] Because the structure is complex, there are many parts, and it takes a lot of time to assemble. This results in high costs.
【０００８】[0008]
本考案は上記の課題を解決し、装置全体を小型・軽量化しひいては耐振性に優 れ、部品点数、組立工数を低減でき、安価に実施できる可変同調共振器を提供す るものである。 即ち、本考案可変同調共振器は、図１に示すようにシャーシ１の軸案内部１ａ に枢支された回転軸２Ａの回転運動を直線運動に変換させて中心導体の長さを可 変し同調周波数を変化させる、無線通信機等に用いられる可変同調共振器におい て、前記回転軸２Ａに送りおねじ２を設け、この送りおねじ２に中空中心導体３ の送りめねじ３ａを螺合させ、かつ該送りめねじ３ａの外周部を前記軸案内部１ ａに軸方向移動可能で回転不能に嵌挿せしめてなるものである。 This invention solves the above problems, makes the entire device smaller and lighter, and has excellent vibration resistance. We aim to provide a tunable resonator that can be implemented at low cost, reducing the number of parts and assembly man-hours. It is something that That is, as shown in FIG. 1, the variable tuning resonator according to the present invention The length of the center conductor can be adjusted by converting the rotational motion of the rotating shaft 2A, which is pivotally supported by the In tunable resonators used in wireless communication equipment, etc., which change the tuning frequency. A feed screw 2 is provided on the rotating shaft 2A, and a hollow center conductor 3 is attached to the feed screw 2. The female feed screw 3a is screwed together, and the outer circumference of the female feed screw 3a is connected to the shaft guide portion 1. a, which is movable in the axial direction but is fitted in a non-rotatable manner.

このような構成とすることにより中空中心導体３は必要最小限の大きさで製作 でき、前記した様に中空中心導体３の外径によりシャーシ１の大きさが決定され るため必然的に共振器全体を小型・軽量化できることになると共に、中空中心導 体３の重量が軽減できるため、重量を増すことなく耐振性が得られ、送りおねじ ２の回転トルクを小さくすることができることになる。又、構造も従来に比較し 、簡略できるため、部品点数，組立工数を低減でき、安価に実施できるばかりで なく、組立時間の削減を図ることができることになる。 With this configuration, the hollow center conductor 3 can be manufactured with the minimum necessary size. As mentioned above, the size of the chassis 1 is determined by the outer diameter of the hollow center conductor 3. Therefore, the entire resonator can be made smaller and lighter, and a hollow center conductor can be used. Since the weight of the body 3 can be reduced, vibration resistance can be obtained without increasing the weight. This means that the rotational torque of No. 2 can be reduced. Also, the structure is compared to the conventional one. , because it can be simplified, the number of parts and assembly man-hours can be reduced, and it can be implemented at low cost. Therefore, it is possible to reduce the assembly time.
