本発明は貫通形コンデンサに係り、特に誘電体の内外周
を各々電極とするコンデンサに好適な構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a feedthrough capacitor, and particularly to a structure suitable for a capacitor in which the inner and outer circumferences of a dielectric material are used as electrodes.

７−１０４４４６号公報が挙げられる。Among conventional feedthrough capacitors, in which electrodes are formed on the inner and outer peripheries of a cylindrical dielectric, the electrode plate connected to the outer circumferential surface of the dielectric is plate-shaped, with a through hole provided therein and the dielectric inserted into the through hole. It is attached to the outer circumferential surface of the body. Incidentally, related to this type of feedthrough capacitor is 5, for example,
7-104446 is mentioned.

てコンデンサ機能を損なってしまう。As shown in FIG. 2, the above-mentioned conventional technology involves providing a through hole 7' in a plate-shaped electrode plate 7, fitting the dielectric 1 therein, and fixing it by soldering. When a shock test is performed, stress occurs due to the fact that the electrode plate made of metal and the dielectric made of ceramic have a large coefficient of thermal expansion, especially on the outer periphery of the dielectric with a large diameter. In turn, this causes cracks in the dielectric material, and when high voltage is applied, it breaks down, impairing the function of the capacitor.
本発明の目的は、上記熱ストレスの集中をさけ分散させ

上記目的は、電極板の誘電体を挿通する部分を筒状に形

熱ストレスを局部的に集中させないようにしたことによ
り、達成される。The above purpose is to form the part of the electrode plate that passes through the dielectric into a cylindrical shape, and to connect the half-date to the outer peripheral surface of the dielectric on almost the entire surface.
This is achieved by preventing heat stress from being locally concentrated.
誘電体の外周面が全面的に電極板に半田付けされるので
、熱ストレスが接合面で分散され、誘電体のクラックを
防止する。Since the entire outer circumferential surface of the dielectric is soldered to the electrode plate, thermal stress is dispersed at the joint surface, preventing cracks in the dielectric.

電極板３にはめ込まれている。An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a dielectric material made of ceramics whose inner and outer circumferential surfaces are, for example, entirely plated with Ni, and then the upper and lower end surfaces are ground to leave a metallized film on the inner and outer circumferential surfaces as electrodes. A center conductor 2 is inserted into the dielectric 1 and fixed by soldering or the like. On the other hand, an electrode plate 3 is connected to the outer peripheral surface of the dielectric 1. Here, the electrode plate 3 forms a cylindrical portion 3a and is soldered or otherwise connected to the outer peripheral surface of the dielectric 1 almost entirely. Join. A filled resin 4 is housed in a plastic case of 5°6, and the cases 5 and 6 are fitted into the electrode plate 3.
尚、第１図では１ケの誘電体１に対して１ケの中心導体

導体を挿通したものでも全く同様の効果を奏する。In FIG. 1, one center conductor is used for one dielectric 1, but the same effect can be obtained by inserting two or more center conductors as necessary.

レスを電極板で分散して受ける形となり信頼性の高い貫
通コンデンサを容易に得ることが出来る。According to the present invention, the thermal stress generated between the dielectric and the electrode plate is distributed and received by the electrode plate, and a highly reliable feedthrough capacitor can be easily obtained.
