を溶融させ、気密端子を製造した。The present invention relates to a method for manufacturing an airtight terminal. When glass is used as an electrical insulator, the typical conventional manufacturing method for airtight terminals is to granulate glass powder into granules, mold and fire the granules to obtain glass tablets, and prepare the glass tablets with the glass tablets in advance. A metal ring and lead terminal with appropriate back surface treatment are
The glass was assembled into a sealing jig and the sealing jig was heated to a high temperature to melt the glass, thereby producing an airtight terminal.
この方法は、信頼性の高い気密端子が得られる反面、製
造工程が長く、安価な製品を得ることが容易ではなかつ
た。Although this method provides a highly reliable hermetic terminal, the manufacturing process is long and it is not easy to obtain an inexpensive product.
本発明の目的は、電気絶縁体の製造工程を簡略化するこ
と、及びガラス封着などに見られるような、材質選定の
制約を取除くことにある。An object of the present invention is to simplify the manufacturing process of electrical insulators and to remove restrictions on material selection, such as those seen in glass sealing.
以下添付図面にもとづいて、本発明の一実施例を説明す
る。An embodiment of the present invention will be described below based on the accompanying drawings.
第１図は、アルミナの円筒状棒１の全面にタングステン
２をメタライズし、更にその上にニッケルロウメッキ３
を施したものである。In Figure 1, tungsten 2 is metallized on the entire surface of an alumina cylindrical rod 1, and nickel brazing 3 is further plated on top of it.
It has been subjected to
セラミックスのメタライズについては、テレフンケン法
、活性金属法、蒸着、金属酸化物の還元熱処理等、公知

ターで一定寸法に輪切状に切断し、セラミックスのリン
グ４を得る。Regarding metallization of ceramics, known techniques such as the Telefunken method, active metal method, vapor deposition, and reduction heat treatment of metal oxides can be applied. In FIG. 2, a cylindrical rod 1 on which wax plating is applied on a metallized layer is cut into circular slices of a constant size using a diamond grindstone cutter to obtain a ceramic ring 4.
切断された該リング４は、外周面及び穴内面にロウメッ
キ層３を有するが、切断面５にはセラミックスの素地が

３図は、セラミックスリング４の冗の中にリード端子６
を挿入し、外周には金属環７をはめて弱還元性雰囲気の
熱処理炉で９５０℃以上に加熱し、相互の部品をロウ接
したものである。The cut ring 4 has a wax plating layer 3 on the outer peripheral surface and the inner surface of the hole, but a ceramic base is exposed on the cut surface 5, blocking electrical conduction between the outer peripheral surface and the inner surface of the hole. Figure 3 shows a lead terminal 6 inside the ceramic ring 4.
was inserted, a metal ring 7 was fitted around the outer periphery, and the parts were heated to 950° C. or higher in a heat treatment furnace with a weakly reducing atmosphere, and the mutual parts were brazed together.
伺ここで、ロウ接のかわりに半田付けを行なうこともあ
る。At this point, we sometimes do soldering instead of soldering.
これにより金属環７とリード端子６を電気絶縁した気密
端子を得ることができる。As a result, an airtight terminal in which the metal ring 7 and the lead terminal 6 are electrically insulated can be obtained.
以上記載の本発明によれば、電気絶縁体の製造工程を簡
略化でき、一般にガラス封着に見られるリード端子、金
属環の酸化処理或いは脱炭処理を省くことができる等、
安価な気密端子を提供することが可能である。According to the present invention described above, the manufacturing process of an electric insulator can be simplified, and the oxidation treatment or decarburization treatment of lead terminals and metal rings, which is generally seen in glass sealing, can be omitted, etc.
It is possible to provide an inexpensive airtight terminal.
又、リード端子、金属環には、ロウ接或いは半田付け可
能なすべての材料を使用することができる。Moreover, all materials that can be soldered or soldered can be used for the lead terminal and the metal ring.
従来の穴明きガラスタブレットを使用する場合、冗の径
がφ０．５ｍｍ程度になると、粉末の成形が困難になる
が、本発明によれば更に小径の冗を設けることも可能で
ある。When a conventional perforated glass tablet is used, it becomes difficult to mold the powder when the diameter of the hole is about 0.5 mm, but according to the present invention, it is also possible to provide a hole with an even smaller diameter.
