It is connected to an external lead 3 via a molybdenum foil (not shown) sealed in the sealing part 2 . The external lead 3 forms a lead member having a structure as shown in FIG. 6, for example. That is, an external lead 3 led out from the crushing sealing part 2 and a conducting wire 5 having an insulating coating 4 are arranged in parallel, and the tip of the conducting wire 5 is connected by welding or the like by covering the external lead 3 with a nickel sleeve 6 or the like. . On the other hand, the tip of the external lead 3 is covered with a sleeve 7 together with the conducting wire 5, and is caulked and connected by welding or the like, so that it will not break even if an external force is applied to the connection point. Furthermore, a lead member 9 is constructed by moving an insulating tube 8 in the direction of the arrow and covering this connection portion. The cap member 10 consists of a cap piece 11 and a cap cap 13, and the cap member 11 is arranged on one side of the crushing sealing part 2, and the cap cap 13 is arranged on the other surface.
The claw 14 formed on the cap piece 11 is engaged with the notch of the mouth cap 13, and then the claw 14 is bent inward so that the cap piece 11 and the mouth cap 13 sandwich the crushing sealing part 2. Fixed. The lead member 9 is placed on the cap member 10, and the insulating tube 8 is fastened by caulking the clamping claws 15 of the stator 12 of the cap piece 11 from above the insulating tube 8.

から外部リード3が絶縁チユーブ8に被覆されな
いで露出部16が残る虞がある。 In the conventional configuration as described above, the crush sealing portion 2 side of the insulating tube 8 is cut off at right angles to the axis of the insulating tube 8, so that the crush sealing portion 2 side is cut off at right angles to the axis of the insulating tube 8, so that the crush sealing portion 2 side is cut off at right angles to the axis of the insulating tube 8. If the tip of the portion 2 is not formed perpendicular to the axis, the tip of the insulating tube 8 will not move to a position other than the position where it abuts the crush sealing portion 2, so the external lead 3 will not be covered by the insulating tube 8 and will be exposed. There is a possibility that 16 will remain.
上記の圧潰封止部2の先端が軸に直角に形成さ

軸に直角にグラインダで切削処理する方法を行つ
たが、製造の工数が増加し、作業が難しく、さら
に封止端部の欠落や亀裂不良が増大するという問
題が発生した。 If the tip of the crushed sealing part 2 mentioned above was not formed perpendicular to the axis, a method was used in which the tip of the sealing part was cut with a grinder at right angles to the axis, but this increased the number of manufacturing steps. However, the work was difficult, and furthermore, there were problems in that the number of defects such as chipping and cracking of the sealing end increased.

A tungsten filament is sealed inside along the tube axis, and its ends are connected to external leads via molybdenum foil (not shown) sealed in flat crushed sealing parts 18, 18 at both ends of the tube-shaped glass bulb 17. It is connected to the. The above tungsten filament is a tube-shaped glass bulb 17

The present invention has a lead wire member in which an external lead led out from a crush sealing portion at the end of a tubular glass bulb containing a tungsten filament is covered with an insulating tube, and the lead wire member is sealed in the crush seal. In a tube-shaped light bulb that is engaged with a cap member fixed to a portion, the insulating tube has a notched end formed therein, the notched end sandwiching the crushed sealing portion;
Since the structure does not expose the conductor near the crushed sealing part, the external lead of the lead member is not exposed from the tip of the crushing sealing part, so it is electrically safe and prevents corrosion of the external lead. There is little breakage, there is no need to cut the tip of the crushed sealing part, and there is no increase in manufacturing man-hours, so it has the effect that a safe tube-shaped light bulb can be manufactured at low man-hours.
