【発明の詳細な説明】
本発明は圧電共振子を用いたセラミックフィルタの製造
方法、特にその絶縁ケースに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a ceramic filter using a piezoelectric resonator, and particularly to an insulating case thereof.
一般にセラミックフィルタはセラミックフィルタの構成
要素を絶縁ケース内に所望の順序で収納後機械的に挾持
している。In general, ceramic filters have components of the ceramic filter housed in an insulating case in a desired order and then mechanically clamped.
しかし構成要素を絶縁ケース内に収納する際、構成要素
が絶縁ケース底面に倒れたり、絶縁ケースよりはみでた
り、落下したりするため収納が非常に困難であった。However, when storing the components in the insulating case, it is very difficult to store the components because they may fall to the bottom of the insulating case, protrude from the insulating case, or fall.
特に半分以上収納した時点で構成要素が落下すると再度
収納を行なう必要があり非常に多（の工数を要する。In particular, if a component falls when more than half of the components are stored, it is necessary to store them again, which requires a very large number of man-hours.
さらに圧電共振子が直接絶縁ケース内面に接触するとフ
ィルタの振動作用を阻害する。Furthermore, if the piezoelectric resonator directly contacts the inner surface of the insulating case, the vibration effect of the filter will be inhibited.
本発明は上記欠点を除去し、セラミックフィルタの製造
方法を簡単確実にしたものである。The present invention eliminates the above-mentioned drawbacks and makes the method of manufacturing a ceramic filter simple and reliable.
第１図および第２図は本発明によるセラミックフィルタ
の製造方法の説明図である。FIGS. 1 and 2 are explanatory diagrams of a method for manufacturing a ceramic filter according to the present invention.
第１図に示すように、１は薄肉圧電共振子、２は厚肉圧
電共振子で、これらの圧電共振子１および２の振動接点
に小突起を有する端子板３が当接されている。As shown in FIG. 1, 1 is a thin-walled piezoelectric resonator, 2 is a thick-walled piezoelectric resonator, and a terminal plate 3 having small protrusions is brought into contact with the vibrating contacts of these piezoelectric resonators 1 and 2.
４は絶縁板で所望の回路を構成するため、該端子板間に
挿入されている。Reference numeral 4 denotes an insulating plate inserted between the terminal plates to form a desired circuit.
５はケースで内面に粘着剤６を塗布してあり、薄肉圧電
共振子１、厚肉圧電共振子２、端子板３および絶縁板４
等のセラミックフィルタ構成要素を所望の順序でケース
５内に収納し、弾性体７０弾性力によって一体装着する
。5 is a case whose inner surface is coated with an adhesive 6, which includes a thin-walled piezoelectric resonator 1, a thick-walled piezoelectric resonator 2, a terminal plate 3, and an insulating plate 4.
The ceramic filter components such as the above are housed in the case 5 in a desired order and are integrally attached by the elastic force of the elastic body 70.
次に第１図の状態で有機溶剤の中に浸種し、粘着剤６の
みを溶解除去すると第２図のようになる。Next, the state shown in FIG. 1 is immersed in an organic solvent to dissolve and remove only the adhesive 6, resulting in the state shown in FIG. 2.
以上のように本発明によればセラミックフィルタ構成要
素をケース５に収納する際、ケース５の内面に塗布した
粘着剤６の適当な粘着力により構成要素の倒れ、はみ出
し、落下が防止され収納が極めて容易である。As described above, according to the present invention, when a ceramic filter component is stored in the case 5, the appropriate adhesive force of the adhesive 6 applied to the inner surface of the case 5 prevents the component from falling down, protruding, or falling. It's extremely easy.
なお粘着剤ｅは例えば両面接着テープ、スコッチテープ
（登録商標）およびセロテープ（登録商標）等に用いら
れる性質のもので固形化するものではなく、かつ粘着剤
６の粘着力は強力なものではなく、七ラミックフィルタ
構成要素の収納間違いに際しても簡単に脱着することが
できる。Note that the adhesive e is used in double-sided adhesive tape, Scotch tape (registered trademark), Sellotape (registered trademark), etc., and does not solidify, and the adhesive force of adhesive 6 is not strong. Even if the seven ramic filter components are stored incorrectly, they can be easily attached and detached.
またセラミックフィルタ構成要素をケース５に収納装着
後、粘着剤６のみの溶解除去によってセラミックフィル
タ構成要素とケース５の間に僅かな空隙８が生ずるため
、圧電共振子１および２の振動作用に関して理想的な支
持になる。Furthermore, after the ceramic filter component is housed and installed in the case 5, a small gap 8 is created between the ceramic filter component and the case 5 due to the dissolution and removal of only the adhesive 6, which is ideal for the vibration action of the piezoelectric resonators 1 and 2. It will be a support.
上記のごとく本発明は単にケース５の内面に粘着剤６を
用いるだけで極めて精度が高く、経済的なセラミックフ
ィルタの提供を可納にしたものである。As described above, the present invention makes it possible to provide an extremely accurate and economical ceramic filter simply by using the adhesive 6 on the inner surface of the case 5.
