【考案の詳細な説明】
本考案はガスセンサ用ステムに好適するガラス封止端子
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass-sealed terminal suitable for a stem for a gas sensor.
ガスセンサ用のガラス封止端子は、例えば第１図に示す
ように、金属外環１にリード線２をガラス３を介して、
かつ金属外環１とリード線２との間の沿面距離を大きく
するために、ガラス３が金属外環１から突出状に封止さ
れており、金属外環１およびリード線２が鉄・ニッケル
・コバルト合金よりなり、ガラス３がホウケイ酸ガラス
からなるのが普通である。For example, as shown in FIG. 1, a glass-sealed terminal for a gas sensor includes a lead wire 2 connected to a metal outer ring 1 through a glass 3.
In addition, in order to increase the creepage distance between the metal outer ring 1 and the lead wires 2, the glass 3 is sealed in a protruding manner from the metal outer ring 1, and the metal outer ring 1 and the lead wires 2 are made of iron/nickel. - It is made of cobalt alloy, and the glass 3 is usually made of borosilicate glass.
ところが、金属材料として鉄・ニッケル・コバルト合金
を用いると、硫酸や硝酸のミストによって、ガラス封止
界面やメツシュ状キャップの溶接界面で発錆しやすいの
みならず、鉄・ニッケル・コバルト合金が高価なため、
ガラス封止端子が高価になるという問題点があった。However, when iron, nickel, and cobalt alloys are used as metal materials, they not only tend to rust at glass sealing interfaces and welded interfaces of mesh caps due to sulfuric acid or nitric acid mist, but also make iron, nickel, and cobalt alloys expensive. For some reason,
There was a problem that the glass-sealed terminal was expensive.
本考案はこのような問題点を解決するために提案された
もので、以下実施例を図面により説明する。The present invention was proposed to solve these problems, and embodiments thereof will be described below with reference to the drawings.

突出状に封止されている。a = 89 x 10 -7 cm/cm/deg) The glass 14 is sealed in a protruding manner from the metal outer ring 11 .
すなわち、本考案は発錆および材料費の観点から、金属
外環１１およびリード線１３の材質を特定し、かつこの
金属材料との封着性を考慮してガラス１４の材質を特定
したものである。That is, in the present invention, the material of the metal outer ring 11 and the lead wire 13 is specified from the viewpoint of rust generation and material cost, and the material of the glass 14 is specified in consideration of the sealing property with the metal material. be.
このような構成であると、金属外環１１およびリード線
１３が硫酸や硝酸のミストによって発錆することがなく
、シかも鉄・ニッケル・クロム・合金や鉄・ニッケル合
金は鉄・ニッケル・コバルト合金に比較して安価である
ので、従来と比べて品質の良いガラス封止端子が安価に
提供できる。With such a configuration, the metal outer ring 11 and the lead wire 13 will not rust due to sulfuric acid or nitric acid mist, and iron/nickel/chromium alloy or iron/nickel alloy may be replaced by iron/nickel/cobalt. Since it is cheaper than alloys, it is possible to provide glass-sealed terminals of better quality at a lower cost than conventional ones.
第３図は第２の実施例で金属外環２１が、鉄・ニッケル
・クロム合金をキャップ状にプレス成型した点を除いて
は、第２図と同様であるため、第２図と同一部分または
対応部分に同一参照符号を付したので、その説明を省略
する。Figure 3 shows the second embodiment, which is the same as Figure 2 except that the metal outer ring 21 is press-molded from an iron-nickel-chromium alloy into a cap shape, so the parts are the same as in Figure 2. Or, since corresponding parts are given the same reference numerals, the explanation thereof will be omitted.
第４図は第３の実施例で、金属外環３１が比較的厚い金
属板をプレス加工して製作されている点を除いては第２
図と同様であるため、第２図と同一部分または対応部分
に同一参照符号を付したので、その説明を省略する。FIG. 4 shows the third embodiment, which is similar to the second embodiment except that the metal outer ring 31 is manufactured by pressing a relatively thick metal plate.
Since it is similar to the figure, the same reference numerals are given to the same or corresponding parts as in FIG. 2, and the explanation thereof will be omitted.
本考案は以上のように、発錆のないガラス封止端子が安
価に提供できるという効果を奏する。As described above, the present invention has the effect of providing a rust-free glass-sealed terminal at a low cost.
