Description
【発明の詳細な説明】 本発明は管球に関するものである。[Detailed description of the invention] The present invention relates to a tube.
従来から、キセノン灯や水銀灯等においては、タングス
テンまたはトリャタングステン等からなる電極棒に石英
等の封着ガラスを溶着し（以下電極棒封着部という）、
この電極棒の外側端部にリード線の一端部を接続し、前
記封着ガラスに発光管本管を接合して発光管を形威し、
この発光管の端部に口金を取付け、前記リード線の他端
部を口金に半田等で接続した構造を採っていた。Conventionally, in xenon lamps, mercury lamps, etc., a sealing glass such as quartz is welded to an electrode rod made of tungsten or toryatungsten (hereinafter referred to as the electrode rod sealing part).
Connecting one end of the lead wire to the outer end of the electrode rod and joining the arc tube main tube to the sealing glass to form an arc tube,
A structure was adopted in which a cap was attached to the end of the arc tube, and the other end of the lead wire was connected to the cap with solder or the like.
ところが、この管球の製造工程中、電極棒に封着ガラス
を溶着する工程、および発光管本管に上記電極棒封着部
を封止する工程は、還元ガスまたは不活性ガスの雰囲気
中で加熱して行われるため、電極棒の金属が再結晶化し
、その外側端部、とくに封着ガラスとの境目の外側端部
が非常に脆く折れやすい状態になる。However, during the manufacturing process of this tube, the process of welding the sealing glass to the electrode rod and the process of sealing the electrode rod sealing part to the main arc tube are performed in an atmosphere of reducing gas or inert gas. Since this is done by heating, the metal of the electrode rod recrystallizes, and its outer end, especially the outer end at the boundary with the sealing glass, becomes extremely brittle and easily broken.
そのため、発光管本管に電極棒封着部を封止する時、電
極棒にリード線を溶接する時、管球の排気時、または口
金の取付時等に電極棒の外側端部に無理な力が加わって
これが折れやすいという欠点があった。Therefore, when sealing the electrode rod sealing part to the main arc tube, welding the lead wire to the electrode rod, exhausting the tube, or attaching the cap, it is necessary to avoid applying force to the outer end of the electrode rod. It had the disadvantage that it easily broke when force was applied.
とくに、このような構造を採るキセノン灯や水銀灯等で
、非常に細い光源や輝度の高い光源を得るには、発光管
本管の径を極端に小さくする必要がある。In particular, in xenon lamps, mercury lamps, and the like that adopt such a structure, in order to obtain a very thin light source or a light source with high brightness, it is necessary to make the diameter of the main arc tube extremely small.
たとえば発光管本管の径が１１ｎ１ＩＬ以下のものの場
合には、電極棒は管球の特性や製造の難度を考慮して０
．６ｍｍ以下の径のものにしなければならない。For example, if the diameter of the arc tube main tube is 11n1IL or less, the electrode rod should be
．． It must have a diameter of 6 mm or less.
電極棒が０．６■の径である場合、その外側端部の機械
的強度は著しく低下し、上述のように、発光管本管に電
極棒封着部を封止する時等において、外側端部が非常に
折れやすい。When the electrode rod has a diameter of 0.6 mm, the mechanical strength of the outer end is significantly reduced, and as mentioned above, when sealing the electrode rod sealing part to the main arc tube, etc., the outer end The edges break very easily.
本発明は、上述のごとき欠点に鑑みてなされたもので、
管球の製造中または使用中における金属棒の外側端部に
折れを防止することを目的とする。The present invention has been made in view of the above-mentioned drawbacks.
The purpose is to prevent bending of the outer end of the metal rod during manufacture or use of the tube.

である。The present invention provides an electrode rod, a sealing glass welded around the electrode rod leaving both ends of the electrode rod, and an arc tube main body that forms an arc tube by being joined to the sealing glass. a tube, a metal tube that is fitted into the outer end of the electrode rod so as to surround the welded portion of the sealing glass and connected to the electrode rod, and one end of which is fixed to the end of the arc tube. The present invention is characterized by a tube including a cap having a cylindrical shape and a lead wire having an end connected to the cap and the other end connected to the metal tube.
以下、本発明の一実施例について、図面を参照しつつ説
明する。An embodiment of the present invention will be described below with reference to the drawings.
この実施例の小型管球は、第１図に示すように、太さ０
． ５ ｍｍのタングステンからなる電極棒１に両端部
を残して、封着ガラス２が溶着され、さらにこの溶着部

４が、外部リード棒を兼ねている上記電極棒１の外側端
部５に圧着されている。The small tube of this embodiment has a thickness of 0 as shown in FIG.
．． A sealing glass 2 is welded to an electrode rod 1 made of 5 mm tungsten, leaving both ends intact, and a metal tube 3 such as a nickel pipe is inserted into this welded portion, and its end 4 is connected to an external lead rod. It is crimped to the outer end 5 of the electrode rod 1, which also serves as the electrode rod 1.
そして、上記外側端部５にリード線６が接続され、発光
管本管７の内部に上記電極棒が入れられ、還元ガスまた
は不活性ガスの雰囲気中で、発光管本管７と封着ガラス
２との接合部を加熱して、両者を同軸同方向に回転させ
ながら接合を行う。Then, a lead wire 6 is connected to the outer end 5, and the electrode rod is placed inside the arc tube main tube 7, and the arc tube main tube 7 and the sealed glass are placed in an atmosphere of reducing gas or inert gas. The joint with 2 is heated and the joint is performed while rotating both on the same axis and in the same direction.
次に、封着ガラス２および金属管３に口金９が耐熱セメ
ント８で取付けられ、口金９とリード線６が半田１０等
で電気的に接続されて完威される。Next, the cap 9 is attached to the sealing glass 2 and the metal tube 3 with heat-resistant cement 8, and the cap 9 and the lead wire 6 are electrically connected with solder 10 or the like to complete the process.
上述のごとき構造を有する管球の場合、製造中も使用中
も電極棒の外側端部の折れは皆無であった。In the case of the tube having the above-described structure, there was no bending of the outer end of the electrode rod during manufacture or use.
また、電極棒が０．４ｍｍの太さのものである場合も同
様であった。The same thing happened when the electrode rod had a thickness of 0.4 mm.
本発明によりこのような電極棒の外側端部の折れが解消
できるのは、電極棒への封着ガラスの溶着時の熱によっ

伝えられたとしても無視できる程度であるからであると
考えられる。The present invention can eliminate such bending of the outer end of the electrode rod because the sealing glass is recrystallized by the heat during welding to the electrode rod, and the outer end, which is extremely brittle and easily broken, can be replaced with a metal tube. In addition, since this metal tube is inserted into the sealing glass, when sealing the electrode rod sealing part in the main arc tube, when electrically connecting the lead wire to the electrode rod, etc., the electrode Even if an unreasonable force is applied to the outer end of the rod, this force will be absorbed by the metal tube and will not be transmitted to the outer end, especially the outer end at the boundary with the sealing glass, which is easy to break. This is thought to be because even if it were communicated, it would be negligible.
これに対し、従来のように、金属管を使用しなかった場
合には、電極棒径が０．６ｍｍ、０．５間のとき、電極
棒の外側端部の折れが５０％生じた。On the other hand, when the metal tube was not used as in the conventional case, when the diameter of the electrode rod was between 0.6 mm and 0.5 mm, the outer end of the electrode rod was bent by 50%.
