本考案は、ケース内において電極板間に圧電磁器共振子
を挟持するラダー形セラミックフィルタに関するもので
ある。[Detailed Description of the Invention] The present invention relates to a ladder-type ceramic filter in which a piezoelectric ceramic resonator is sandwiched between electrode plates within a case.
以下に本考案の一実施例について第１図〜第３図ととも
に説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.
第１図〜第３図において、１は一端か゛閉成した筒状の
ケースであり、このケースの上面にはケース１の軸方向

行なスリツｌ−３，３’が形威されている。In Figs. 1 to 3, 1 is a cylindrical case with one end closed, and a protrusion 2 extending in the axial direction of the case 1 is integrally formed on the upper surface of the case. Parallel slits l-3, 3' are formed on both sides.
４は上記ケース１の開口端部を閉塞する蓋板であり、こ
の蓋板４には上記突片２が嵌合する凹部５が形威されて
いる。Reference numeral 4 denotes a cover plate that closes the open end of the case 1, and the cover plate 4 has a recess 5 into which the protrusion 2 fits.
６は上記ケース１内に収納された円板状の圧電磁器共振
子であり、この圧電磁器共振子６は電極板７により挟持
されている。Reference numeral 6 denotes a disk-shaped piezoelectric ceramic resonator housed in the case 1, and this piezoelectric ceramic resonator 6 is held between electrode plates 7.
なお上記電極板７の内外部回路と接続する必要のある電
極板７には第２図に示すように長い端子８と、短い補助
端子９とが一体に形成されている。As shown in FIG. 2, a long terminal 8 and a short auxiliary terminal 9 are integrally formed on the electrode plate 7, which needs to be connected to the internal and external circuits of the electrode plate 7.
また外部回路に接続する必要のない電極板７には第３図
に示すように２個の補助端子９，９′が形威されている
ものであり、これら端子８、補助端子９，９′は前記ス
リツ）３．３’に挿入されているものである。Further, the electrode plate 7, which does not need to be connected to an external circuit, has two auxiliary terminals 9, 9' as shown in FIG. is inserted into the slot 3.3'.
１０は上記ケース１の蓋板４側の端部に収納された弾性
体であり、この弾性体１０の弾性力により、圧電磁器共
振子６は適度の押圧力により電極板７間に挟持されるも
のである。Reference numeral 10 denotes an elastic body housed in the end of the case 1 on the cover plate 4 side, and due to the elastic force of this elastic body 10, the piezoelectric ceramic resonator 6 is sandwiched between the electrode plates 7 with an appropriate pressing force. It is something.
従来のこの種のラダー形セラミックフィルタにおいては
、第４図に示すように、電極板１１に一本の端子１２の
みを一体に形成し、この電極板１１の形状とケース１の
内部の形状とを相似形とするか、または第５図に示すよ
うに、電極板１１に平行な側部を形成し、ケース１内の
平行な内側面に当接させて、電極板１１の位置規制を行
っている。In this type of conventional ladder-type ceramic filter, as shown in FIG. The position of the electrode plate 11 is regulated by making it similar in shape, or by forming a parallel side part to the electrode plate 11 and making it abut against the parallel inner surface inside the case 1, as shown in FIG. ing.
しかしながら、第４図に示すように電極板１１の形状を
四角形としたり、または第５図に示すように電極板１１
に平行な側部を形成する場合には、ケース１の内部に平
行な側面を形威しなければならず、このため、ケース１
の小型化をはかるとケース１の肉厚が薄くなりケース１
の強度が弱くなる欠点があり、一方ケース１の強度を保
証しようとすれば、ケース１が大型になる欠点があった
。However, as shown in FIG. 4, the shape of the electrode plate 11 is square, or as shown in FIG.
When forming parallel sides to the case 1, the parallel sides must be formed inside the case 1, and for this reason, the case 1
When miniaturizing Case 1, the wall thickness of Case 1 becomes thinner.
However, if the strength of the case 1 was to be guaranteed, the case 1 would have to be large.
これに対して本考案では、長い端子８と短い補助端子９
、または２個の補助端子９，９′とをそれぞれスリット
３，３′に係合させて、電極板７の位置規制を行ってい
るため、ケース１の内部形状を、圧電磁器共振子６の形
状に近づけることが可能になり、ケース１の外形が小型
で、かつケース１の肉厚を厚くして充分な強度を保証で
きる利点を有するものである。In contrast, in the present invention, the long terminal 8 and the short auxiliary terminal 9
, or the two auxiliary terminals 9 and 9' are engaged with the slits 3 and 3', respectively, to regulate the position of the electrode plate 7. This has the advantage that the outer shape of the case 1 is small, and the wall thickness of the case 1 is increased to ensure sufficient strength.
以上のように本考案によれば、電極板が安定に保持され
、かつ小型で充分な強度が保証されるラダー形セラミッ
クフィルタが得られるものである。As described above, according to the present invention, it is possible to obtain a ladder-type ceramic filter in which the electrode plates are stably held, and which is small in size and has sufficient strength.
