Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method of manufacturing a filament support structure for a 100V type single-sealed halogen lamp or the like.

[Background of the invention]

The conventional method for manufacturing a filament support structure is to cut a thick high-melting point glass tube into a ring shape 3, and install lead wires 4, 5 and an anchor wire 6 into the ring shape using a jig 2, as shown in FIG. The ring-shaped glass 3 was softened in an inert gas or a reducing gas, and the lead wires 4 and 5 and the anchor wire 6 were fixed thereto. In these conventional methods, firstly, since the ring-shaped glass 3 with a large diameter is used, the jig 2 for fixing the lead wire to be implanted has a complicated structure;
Furthermore, in order to secure the lead wires, the large-diameter glass ring must be almost completely softened and its deformation increased to ensure sufficient fixation, which requires a long heating time. There were drawbacks.

[Purpose of the invention]

An object of the present invention is to solve these drawbacks and provide a manufacturing method that requires almost no manufacturing jig, hardly deforms the glass necessary for fixing the wire to be implanted, and shortens the heating time. 6 [Summary of the Invention] In order to achieve the above object, the wire to be planted and the glass are brought into almost close contact from the beginning. In other words, by making a cut approximately equal to the wire diameter of the wire to be implanted in the glass rod or tube and inserting the wire into the cut, a method can be provided in which the wire can be fixed to the glass by slightly softening and deforming the glass. We have discovered a highly efficient manufacturing method that takes less time to soften and heat the glass.

[Embodiments of the invention]

As shown in FIG. 2, two cuts of 0.5 mm width are made at a depth of about 1.5 mm for the lead wires 4 and 5 in a quartz rod 7 with a diameter of 3 cm, which is a high melting point glass, and the anchor wires 6 are For use, make a 0.25 rm width cut of approximately 1.5 mm.
to a depth of 0.45+ in diameter in each notch.
Lead wires 4 and 5 with a diameter of 0.2 nm and an anchor wire 6 with a diameter of 0.2 nm were inserted. When these were placed on the carbon layer plate 1 and placed in a furnace at 1650 to 1700°C in an inert atmosphere, each wire could be fixed to the quartz rod by heating for 5 minutes.

In addition to this example, high melting point glasses with outer diameters of 3 and 5
It was possible to fix the wire to be implanted under almost the same conditions using a glass tube with an inner diameter of about 2 mm.

〔Effect of the invention〕

According to the present invention, the high melting point glass for fixing the wire to be implanted can be prepared in a form close to the desired final shape, and the heating time for fixing can be reduced to about 1/3, and in addition, complicated jigs are not required. There are many advantages such as not having to In particular, it has a large energy-saving effect by shortening the heating time, and since no complicated jig is required, the setting time is short, and the lead wires and anchor wires are less likely to be contaminated by released gas.
