【考案の詳細な説明】 本考案は閃光放電灯に関するものである。[Detailed explanation of the idea] The present invention relates to a flash discharge lamp.
一般に閃光放電灯は、第1図イに示すように、

は、陽極12および陰極23が封体30内におい
て互に対向し、リード棒11および24が外部に
突出する構成を有する。 In general, flash discharge lamps, as shown in Figure 1A,
An anode member 10 includes an anode 12 made of tungsten connected to a lead rod 11 and a glass bead 13 provided in the center thereof, and a sintered electrode at one end of a support rod 21 that also serves as a lead, as shown in FIG. body 22
The support rod 21 of the cathode 23 formed by connecting the
Connect the lead rod 24 to the other end, and then connect the support rod 2
A cathode member 20 having a glass bead 25 provided in the center of the glass tube is manufactured, and then, as shown in FIG.
and glass beads 13 and 2 of cathode member 20
The flash discharge lamp thus obtained has an anode 12 and a cathode 23 facing each other within the envelope 30, and lead rods 11 and 24 It has a structure that protrudes to the outside.
そして、陰極23を構成する焼結電極体22と
支持棒21との接続方法としては、高周波加熱に
よるロウ付法、アーク溶接法、プラズマ溶接法、
一体成形による方法、機械的固定方法などが提案
されているが、以下に述べるような種々の事情が
あり、結局は工程数の多い機械的固定方法が一般
的に用いられている。 The method of connecting the sintered electrode body 22 constituting the cathode 23 and the support rod 21 includes a brazing method using high-frequency heating, an arc welding method, a plasma welding method,
Although integral molding methods and mechanical fixing methods have been proposed, there are various circumstances as described below, and in the end, mechanical fixing methods that require a large number of steps are generally used.
例えば、高周波加熱によるロウ付法において

「エミツター」と呼ばれる電子放射性物質、例え
ばセシウムなどが蒸散してしまうために、高性能
で使用寿命の長い閃光放電灯を得ることができな
い。 For example, in the brazing method using high-frequency heating, a blind hole is made in advance at the connection part of the sintered electrode body into which the tip of the support rod is inserted, and the brazing material and the tip of the support rod are inserted into this blind hole. Therefore, the sintered electrode body and the support rod are connected by brazing, but this method requires a relatively long heating time of several seconds, so the brazing material evaporates. It is not possible to obtain a flash discharge lamp with high performance and a long service life because the envelope blackens and the electron radioactive substances called "emitters" such as cesium in the sintered electrode body evaporate. .
また、アーク溶接法においては、焼結電極体の

とから、前記ロウ付法と同様、焼結電極体のエミ
ツターが蒸散し、使用寿命の長い閃光放電灯を得
ることができず、また溶接部の外観が劣悪であつ
て商品価値を損ねる。 In addition, in the arc welding method, a support rod is opposed to the connection part of the sintered electrode body at a certain distance to generate an arc between the two, and the heat of this arc welds the two. However, according to this method, the entire sintered electrode body is heated by the generated arc and its temperature becomes extremely high, so the emitter of the sintered electrode body evaporates, similar to the brazing method described above. However, it is not possible to obtain a flash discharge lamp with a long service life, and the appearance of the welded part is poor, reducing the commercial value.

のため高能率で確実な溶接を行うことができな
い。 In the plasma welding method, the tip of the support rod is brought into contact with the connection part of the sintered electrode body, and plasma jet is sprayed from a nozzle onto this contact part to weld. Due to the small size of the sintered electrode body and support rod, which are the objects to be welded, the plasma jet does not fly to the part to be welded, but instead hits sharper protrusions near the nozzle, such as the ridgeline of the sintered electrode body. It is easy to fly, and therefore cannot perform highly efficient and reliable welding.

溶接によつて接続されてなる点にある。 The present invention was developed against the above-mentioned background, and includes a cathode that does not contaminate the inside of the enclosure, has excellent characteristics such as no emitter evaporation, has a long service life, and is easy to manufacture. The purpose is to provide a flash discharge lamp, and its feature is that the anode and the cathode, which is formed by connecting a sintered electrode body to one end of a support rod that also serves as a lead, are arranged so that they face each other. In a flash discharge lamp enclosed in an enclosure, the sintered electrode body and support rod are connected by spot welding.

It is usually cylindrical in shape, with a diameter of 3 to 8 mm and a height of 3 to 10 mm. As the support rod 21, a tungsten rod or a molybdenum rod with a diameter of 0.5 to 10 mm is usually used.

Core materials 55 and 56 made of a high melting point metal such as molybdenum are buried in corresponding positions on the lower surface 53 of the upper plate 51 and the upper surface 54 of the lower plate 52, respectively, and support rods are provided on the surfaces of these core materials 55 and 56. Insertion grooves 57 and 58 are formed, and when the upper plate 51 and lower plate 52 are joined, a hole that matches the outer shape of the support rod 21 is formed.

の付近を中性雰囲気に保つことが好ましい。 Important factors affecting spot welding include welding current, current application time, and electrode pressure, but it is required that a sufficient amount of heat is generated in the welded portion, while heat that adversely affects the structure of the sintered electrode body 22 is not generated in the non-welded portion, particularly in the non-welded portion of the sintered electrode body 22. Therefore, it is necessary to supply large energy (large current) to the welded portion in as short a time as possible to suppress heat diffusion to the non-welded portion, and to increase the contact area between the non-welded portion and the welding electrode to reduce the current density in the non-welded portion and efficiently dissipate the generated heat. In addition, in order to prevent oxidation in the welded portion, it is preferable to flow an inert protective gas such as argon into the welded portion to keep the vicinity of the welded portion in a neutral atmosphere.
