この考案は、フイラメントの取付構造に関す
る。[Detailed Description of the Invention] This invention relates to a filament attachment structure.
自動車用ヘツドランプ等において、フイラメン
トの端部をインナーリードに溶接する場合に、金
属部材を介して行われることがある。従来例とし
ては、第１図イに示すように、フイラメントａの
端部にモリブデン製の短筒ｂを嵌めてモリブデン

に示すように、フイラメントa′の端部をＵ字形の
モリブデン板ｄに挾み込んでインナーリードc′に
溶接したもの等がある。 In automotive headlamps and the like, when the end of a filament is welded to an inner lead, it is sometimes done through a metal member. As a conventional example, as shown in Fig. 1A, a short tube b made of molybdenum is fitted to the end of a filament a and welded to an inner lead c made of molybdenum, or as shown in Fig. There is one in which the end of the wire is sandwiched between a U-shaped molybdenum plate d and welded to the inner lead c'.
ところが、前者の場合は、加工費が高く、また
フイラメントに嵌める作業が面倒であり、溶接前
に抜け止めのために扁平につぶす工程を必要とす

際にモリブデン板がズレたり、フイラメントが外
れたりする等の欠点がある。 However, in the former case, processing costs are high, the work of fitting the filament into the filament is troublesome, and a process of flattening the filament to prevent it from coming off is required before welding. On the other hand, in the latter case, there are drawbacks such as the molybdenum plate shifting or the filament coming off during welding.
本考案は、このような従来の欠点を除去するた
めになされ、フイラメントの端部に帯状の金属板
が一方の端部を残して緊密に巻付けられ、かつ残
された一方の端部がインナーリードに溶接された
取付構造を要旨とするものである。 The present invention was devised to eliminate such conventional drawbacks, in which a band-shaped metal plate is tightly wrapped around the end of the filament, leaving one end, and the remaining end is wrapped around the inner end of the filament. The gist is a mounting structure welded to the lead.
以下、図示の実施例により本考案を具体的に説

ブデンで形成され、一方の端部１ａを残してタン

ことにより、前記フイラメント２を取付け固定し
てある。 Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiment. Reference numeral 1 is a band-shaped metal plate made of, for example, molybdenum, and tightly wound around the end of a tungsten filament 2, leaving one end 1a. It is attached. Reference numeral 3 designates an inner lead made of molybdenum, and the filament 2 is attached and fixed by welding the end portion 1a of the metal plate 1.

シメる方法が採れ、フイラメントへの巻付けを能
率良く、しかも確実に行なうことができ、その実
用的効果はきわめて顕著なものがある。 According to the mounting structure of the present invention, since it is not necessary to fit a metal tube onto the end of the filament, the work is easy, and there is no need for a crushing process to prevent it from coming off after fitting the metal tube. In addition, the molybdenum plate does not shift during welding, and the filament does not come off and come out, so the welding work can be done smoothly and poor adhesion and installation errors can be prevented. Furthermore, in the case of the present invention, there is an advantage that the band-shaped molybdenum plate can be wrapped by machine, and a method of crimping can be used at the same time as wrapping, so that wrapping around the filament can be done efficiently and reliably, and its practical effects are extremely remarkable.
