る。 Hereinafter, the present invention will be explained based on the drawings. In Figs. 1 and 2, 1 is a solid type metal base made of metal such as Kovar, and this solid type metal base 1 has holes 2, 2. It is being 3, 3 are lead wires inserted into the holes 2, 2 of the solid type metal base 1;
A molten glass 4 fills the holes 2, 2 of the solid type metal base 1 and seals the lead wires 3, 3, for example, the holes 2, 2 of the solid type metal base 1,
First, the lead wires 3, 3 are inserted through the solid type metal base 1, and then the holes 2, 2 of the solid type metal base 1 are filled with molten glass 4, 4. In this case, lead wires 3, 3
In the middle part of each, there is a wide protruding large diameter part 5,
5 are provided, and the lower surfaces 6, 6 of the large diameter portions 5, 5 are arranged substantially parallel to the lower surfaces 7, 7 of the molten glass 4, 4, and the large diameter portions 5, 5 of the lead wires 3, 3 are connected to the molten glass. 4, 4 and the lower surfaces 7, 7 thereof are sealed.

The large diameter portions 5, 5 of the lead wires 3, 3 are attached to the lower surface 7, 7 of the molten glass 4, 4 on the lower surface of the base, that is, on the side exposed to the outside when formed into an airtight container. Although it was sealed, Figure 3 shows the lead wires 3 and 3.
Another large diameter portion 5a, 5a is provided at a distance from the large diameter portions 5, 5, and these large diameter portions 5, 5a are sealed to the lower surface 7 and upper surface 8 of the molten glass 4, 4. be. In this case, cracks can be prevented on the lower surface 7 and upper surface 8 of the molten glasses 4, 4.

質安定に多大な貢献をする。 As described above, in the airtight terminal of the present invention, the lead wire is provided with a large diameter part, and this large diameter part is sealed together with the lead wire to the lower surface of the molten glass that seals the lead wire. Since the base is firmly sealed to the glass and the bending strength is increased, it is possible to prevent the glass at the base of the lead wire from chipping or cracking due to vibration or impact being applied to the lead wire. It greatly contributes to the stable quality of airtight terminals.
