【従来の技術】[Prior art]

図2にYIG同調発振器の概略の構造を示す。図中10は直流磁場発生手段を 示す。直流磁場発生手段10は例えばフェライトのような磁性体によって形成さ れたツボ形コア11と、このツボ形コア11の上面開口部を蓋して磁路を構成す る蓋コア12と、ツボ形コア11の軸芯位置に設けられた磁芯13と、この磁芯 13を中心に巻装した励磁コイル14とによって構成される。 FIG. 2 shows a schematic structure of the YIG tuning oscillator. Reference numeral 10 in the figure denotes a DC magnetic field generating means. The DC magnetic field generating means 10 includes, for example, a pot-shaped core 11 formed of a magnetic material such as ferrite, a lid core 12 that covers a top opening of the pot-shaped core 11 to form a magnetic path, and a pot-shaped core. It is composed of a magnetic core 13 provided at the axial position of the core 11 and an exciting coil 14 wound around the magnetic core 13.

【0003】 蓋コア12の裏面には配線基板20が取付けられる。この配線基板20にはカ ップリングループ21とその他にYIG発振器を構成する回路素子が実装される 。カップリングループ21はいわゆるワンターンコイルを構成し、カップリング ループ21の中心位置に配置された単結晶磁性球30と磁気的に結合し、単結晶 磁性球30を共振子として作用させて発振回路が構成される。単結晶磁性球30 に直流磁場を与えると、その共振周波数が変化し、発振周波数を周波数掃引させ ることができる。A wiring board 20 is attached to the back surface of the lid core 12. On the wiring board 20, the coupling group 21 and other circuit elements constituting a YIG oscillator are mounted. The coupling group 21 constitutes a so-called one-turn coil, which is magnetically coupled to the single crystal magnetic sphere 30 arranged at the center position of the coupling loop 21 and causes the single crystal magnetic sphere 30 to act as a resonator so that the oscillation circuit Composed. When a DC magnetic field is applied to the single crystal magnetic sphere 30, its resonance frequency changes and the oscillation frequency can be swept.

【0004】 単結晶磁性球30は絶縁体から成る支持軸31によって支持されてカップリン グループ21の中心位置に支持される。支持軸31は磁場発生手段10の内部に おいて支持具32に支持され、単結晶磁性球30をカップリングループ21の中 心位置に支持している。支持具32にはヒータを内蔵し、ヒータによって支持軸 31を加熱し、支持軸31と単結晶磁性球30の温度が一定温度となるように温 度制御が掛けられる。The single crystal magnetic sphere 30 is supported by a support shaft 31 made of an insulator and is supported at the central position of the coupling group 21. The support shaft 31 is supported by a support 32 inside the magnetic field generating means 10, and supports the single crystal magnetic sphere 30 at the center position of the coupling ring 21. A heater is built in the support tool 32, and the support shaft 31 is heated by the heater, and the temperature of the support shaft 31 and the single crystal magnetic sphere 30 is controlled to a constant temperature.

【0005】 単結晶磁性球30をカップリングループ21の中心位置に設定するために、従 来は直流磁場発生手段10の外側に配置した治具40によって支持軸31をX, Y,Z方向に微少量ずつ移動させ、また支持軸31を回転(θ方向)させながら 調整される。 このため支持具32に形成される貫通孔32Aは支持軸31の直径より数倍程 度大きめに形成されている。In order to set the single crystal magnetic sphere 30 at the center position of the coupling group 21, the supporting shaft 31 is conventionally moved in the X, Y, Z directions by a jig 40 arranged outside the DC magnetic field generating means 10. It is adjusted by moving it in small amounts and rotating the support shaft 31 (in the θ direction). Therefore, the through hole 32A formed in the support 32 is formed to be several times larger than the diameter of the support shaft 31.

【0006】 つまり治具40は自己のシャフト41を具備し、このシャフト41を直流磁場 発生手段10の内部に挿入し、支持軸31に連結させ、その連結した状態で支持 軸31をX,Y,Z方向に移動させて単結晶磁性球30の位置を調整する。また X,Y,Z方向に加えて支持軸31を回転させるθ方向の調整も行う。位置が決 まったら、支持具32の貫通孔に接着剤を流し込み支持軸31を支持具32に固 定する。That is, the jig 40 has its own shaft 41, and this shaft 41 is inserted into the DC magnetic field generating means 10 and is connected to the support shaft 31, and the support shaft 31 is connected to the X and Y axes. , Z direction to adjust the position of the single crystal magnetic sphere 30. In addition to the X, Y, and Z directions, the θ direction for rotating the support shaft 31 is also adjusted. After the position is determined, an adhesive is poured into the through hole of the support 32 to fix the support shaft 31 to the support 32.

【考案が解決しようとする課題】[Problems to be solved by the device]

従来は単結晶磁性球30の位置をカップリングループ21の中心位置に設定す るために治具40を用いている。この治具40はX,Y,Zおよびθの4軸調整 手段が必要なため大掛かりであり、また高価である。更に4方向の調整を行わな くてはならないから、その取扱いが面倒で調整に時間が掛かる欠点がある。また 操作に慣れるまでに時間が掛り、作業員の教習に時間が掛かる欠点がある。 Conventionally, the jig 40 is used to set the position of the single crystal magnetic sphere 30 to the center position of the coupling ring 21. This jig 40 is large in size and expensive because it requires means for adjusting the four axes of X, Y, Z and θ. Further, since adjustments in four directions must be performed, there is a drawback that the handling is troublesome and the adjustment takes time. In addition, it takes a long time to get used to the operation, and it takes a long time to teach a worker.

【0008】 この考案の目的は治具を用いることなく単結晶磁性球の位置をカップリングル ープの中心位置に位置合わせすることができるYIG同調発振器の構造を提案す るものである。An object of the present invention is to propose a structure of a YIG tuned oscillator capable of aligning the position of a single crystal magnetic sphere with the center position of a coupling loop without using a jig.

【課題を解決するための手段】[Means for Solving the Problems]

この考案ではカップリングループと支持具とを予め軸合わせした状態で蓋コア に取付けると共に、支持具に形成する支持軸取付用の貫通孔を支持軸の直径に対 して遊びのない直径に選定し、更にカップリングループと支持具との間の距離を 規定し、支持軸を支持具に装着すると単結晶磁性球がカップリングループの中心 位置に装着されるように構成する。 In this invention, the coupling group and the support are preliminarily aligned with each other and attached to the lid core, and the through hole for mounting the support shaft formed in the support is selected to have a play-free diameter relative to the diameter of the support shaft. In addition, the distance between the coupling ring and the support is defined, and when the support shaft is mounted on the support, the single crystal magnetic sphere is mounted at the center position of the coupling group.

【0010】 従って、この考案の構成によれば支持軸を回転させるだけの調整で単結晶磁性 球の位置合わせを済ませることができる。よって高価な調整治具を用いなくても 調整を行うことができ、しかも誰にでも調整を行うことができるので調整時間の 短縮と製造コストの低減も期待できる。Therefore, according to the configuration of the present invention, it is possible to complete the alignment of the single crystal magnetic sphere by adjusting only the rotation of the support shaft. Therefore, the adjustment can be performed without using an expensive adjustment jig, and since anyone can perform the adjustment, it is expected that the adjustment time is shortened and the manufacturing cost is reduced.

【実施例】【Example】

図1にこの考案の一実施例を示す。図1は直流磁場発生手段を構成する蓋コア 12の裏側の面を示す。この考案においては蓋コア12の裏面に予め配線基板2 0と支持具32とを位置合わせした状態で取付ける。つまり配線基板20に取付 けられたカップリングループ21の中心と、支持具32の端部との間の距離Aと 、カップリングループ21の軸芯と支持具32に形成した貫通孔32Aの軸芯と を予め合致させた状態で蓋コア12に取付ける。 FIG. 1 shows an embodiment of this invention. FIG. 1 shows the back side surface of the lid core 12 which constitutes the DC magnetic field generating means. In this invention, the wiring board 20 and the support 32 are attached to the back surface of the lid core 12 in advance in a aligned state. That is, the distance A between the center of the coupling ring 21 mounted on the wiring board 20 and the end of the support 32, the axis of the coupling group 21 and the axis of the through hole 32A formed in the support 32. It is attached to the lid core 12 in a state where the core and the core are matched with each other in advance.

【0012】 これと共に貫通孔32Aは支持軸31の直径よりわずかに大きい程度に選定し 、支持軸31との間に遊びのない状態で支持する。支持軸31の寸法、つまり支 持軸31の先端に支持した単結晶磁性球30の中心から支持軸31の首下までの 寸法LをL=A+Wに選定する。Wは支持具32の幅である。 このように支持軸31の寸法を設定することにより支持軸31を支持具32に 支持させることにより必然的に単結晶磁性球30はカップリングループ21の中 心位置に位置決めされる。従って支持軸31を回転方向θだけ調整すればよい。 回転方向θの調整は単結晶磁性球30の結晶方向を調整し、温度変化に対して発 振周波数の変動が最も少ない回転位置に設定する。At the same time, the through hole 32 A is selected to be slightly larger than the diameter of the support shaft 31 and is supported without play between the support shaft 31 and the support shaft 31. The size of the support shaft 31, that is, the size L from the center of the single crystal magnetic sphere 30 supported at the tip of the support shaft 31 to the underside of the support shaft 31 is selected as L = A + W. W is the width of the support 32. By setting the dimensions of the support shaft 31 in this manner and supporting the support shaft 31 on the support 32, the single crystal magnetic sphere 30 is necessarily positioned at the center position of the coupling ring 21. Therefore, it suffices to adjust the support shaft 31 only in the rotation direction θ. To adjust the rotation direction θ, the crystal direction of the single crystal magnetic sphere 30 is adjusted, and the rotation direction θ is set to the rotation position where the fluctuation of the oscillation frequency is the smallest.

【0013】 位置が決まったら例えばエポキシ樹脂等の接着剤を貫通孔に挿入し、支持具3 2に支持軸31を固定する。After the position is determined, an adhesive such as epoxy resin is inserted into the through hole to fix the support shaft 31 to the support 32.

【0014】[0014]

【考案の効果】 上述したように、この考案によれば予め配線基板20(実質的にはカップリン グループ21)と支持具32とを位置決めして取付けておくことにより、支持軸 31を支持具32に装着するだけで単結晶磁性球30の位置をカップリングルー プ21の中心位置に装着することができる。この結果位置合わせのための調整は 回転方向θだけとなり、誰にでも調整を行うことができる。また調整に要する時 間も短くて済むから製造効率も向上する。また高価な治具を用いなくても済むか ら、これらの点から製造コストを大きく低減することができる効果が得られる。As described above, according to the present invention, the support shaft 31 is supported by the wiring board 20 (substantially the coupling group 21) and the support 32 which are positioned and attached in advance. The position of the single crystal magnetic sphere 30 can be mounted at the center position of the coupling loop 21 only by mounting it on 32. As a result, the adjustment for the alignment is performed only in the rotation direction θ, and anyone can perform the adjustment. In addition, the time required for adjustment can be shortened, which improves the manufacturing efficiency. Further, since it is not necessary to use an expensive jig, the manufacturing cost can be significantly reduced from these points.
