・線を挿入し、これを高温の加熱炉に入れてガラスをｔ
ｊ融させること：こよりリード線を気密的にカラス封着
する方法が一般に採用されている。Conventionally, when manufacturing airtight terminals, a metal outer ring for air-filled terminals is set in a graphite sealing jig, and a tufflet-shaped crow hole is inserted into the lead insertion hole of the metal outer ring.
・Insert the wire and place it in a high temperature heating furnace to heat the glass.
j) Melting: Generally, a method is adopted in which the twisted lead wire is hermetically sealed in a glass.
しかし・ながら、封着治具としてグラファイト製のもの

う問題かあった。That is, when a graphite arrival jig is used, the so-called "carburization phenomenon" occurs in which free particles generated from the arrival jig during high-temperature heating penetrate into the metal outer ring. ＼−
When the base material is stainless steel, this carburization phenomenon increases the hardness of the surface layer of the metal outer ring. Second, if the hardness of the metal outer ring increases, when laser welding other parts to the surface of the metal outer ring, the sudden temperature rise will cause cracks to occur in the metal outer ring, resulting in poor airtightness. There was.

という問題があり、封着治具の耐用期間も短いという問
題があった。In addition, the arriving jig made of graphite is porous, relatively brittle, and has poor abrasion resistance; therefore, a large number of metal outer rings are fitted into each recess of the sealing jig while vibrating the jig. When setting the sealing jig, there is a problem that the surface of the sealing jig is scraped off by the friction, and the generated carbon powder is scattered around the circle, worsening the working environment, and the service life of the sealing jig is also short. There was a problem.

とする。In order to solve the above problems, the present invention provides a sealing jig with
Set the metal outer ring for the terminal, insert the glass and lead wire into the glue insertion hole of the metal outer ring, melt the glass by heating and seal the lead wire, and then attach the metal member to the other metal member. A method of manufacturing an airtight terminal by laser welding is characterized in that the sealing jig is a carbon-based jig, at least the surface layer of which is made of glassy carbon.

ーホン粉飛散による環境悪化を防止することができる。Glassy carbon: Unlike graphite, it is dense and has excellent abrasion resistance, so it rarely generates free carbon or abrasion carbon powder when heated at high temperatures. do not have. Therefore, when a carbon-based jig whose surface layer at least is made of glassy carbon as described above is used as a sealing jig, it is possible to prevent environmental deterioration due to carburization phenomenon and scattering of carphone powder during high-temperature heating.
以下、図面を参照しながら本発明の実施例を詳述する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

In c, for example, a solution prepared by dissolving an incompletely thermally decomposed compound of an organic compound such as a hydrocarbon gas or a hydrocarbon compound in a solvent is applied to the surface of the carbon-based jig 1a, lb, or IC and heated in an inert atmosphere. Or carbon-based jig 1a,
It is formed by applying a special resin treatment to the surface layer portions of 1b and 1c, and is an extremely dense layer with excellent abrasion resistance. Therefore, these carbon-based jigs 1a, lb, and lc hardly generate free carbon during high-temperature heating, and hardly generate carbon powder due to friction or the like.

する。The manufacturing method of the present invention uses the arriving jig 1 consisting of the upper jig 1a, the lower jig 1b, and the bottom jig IC as described above.
It will be implemented as follows. First, before stacking the upper jig 1a in Fig. 1, a large number of metal outer rings 2 for the terminals are supplied onto the upper surface of the lower jig 1b, and the lower jig 1b is vibrated back and forth and left and right. Rock the metal outer ring 2 to the lower jig 1.
Each recess 12b of b: Fit into the recess 12b and set in a predetermined alignment state.

。Even if the metal outer ring 2 is set by vibrating the lower jig 1b as shown in 2, the surface layer 10b of the lower jig 1b is made of the glass-like carphone with good abrasion resistance. Therefore, the upper surface of the lower jig 1b is rarely scraped off due to friction and carbon powder is hardly generated. Therefore, there is no need to worry about carbon powder scattering around and worsening the working environment.

The glass 3 is melted by heating at a high temperature of around 0° C., and the Riet wire 4 is hermetically sealed with the glass to obtain an airtight terminal. Even when heated at high temperatures in this way, the upper jig 1a, the lower jig 1b,
The surface layers 10a, 10b, and 10c of the bottom jig 1c are all made of dense glassy carbon, and there is almost no generation of free carbon, so the hardness of the stainless steel metal outer ring 2 does not increase due to carburization. There aren't many.
