う１３，１４で各電気接点部に接続されている。Example As shown in FIG. 1, a flat sealing part 2 is formed at the end of a bulb 1 made of quartz, and a plurality of grooves 3 are formed at regular intervals on both sides of the flat sealing part 2. (See Figure 2). Two support wires 4, 5 inside the valve 1
A filament coil 6 is provided by. These support wires 4, 5 are connected to external conductors 9, 10 via metal foils 7, 8, respectively. The screw-in type cap 11 is made of E14/20, and the flat sealing part 2
The troughs are screwed into the grooves 3 on both sides of the flat sealing part 2, and an adhesive 12 is filled between at least both sides of the flat sealing part 2 and the cap 11 to fix the cap 11 to the flat sealing part 2. It's summery. Both external conductive wires 9 and 10 are drawn out of the base 11, and their respective tips are connected to respective electrical contact portions with silver solders 13 and 14.
なお、第１図中、１５は絶縁物を示す。 In addition, in FIG. 1, 15 indicates an insulator.

着するので、口金１１の固着構造が従来に比べて
簡単となり、製作が容易で安価となるものであ
る。しかも、磁器製受部を使用していないことか
ら、従来に比べて機械的強度が大となるものであ
る。 As described above, in the bulb according to the embodiment of the present invention, the plurality of grooves 3 formed on both sides of the flat sealing part 2
Since the trough of the cap 11 is screwed into the holder and the adhesive 12 is filled between both sides and the trough, the adhesion strength between the two is high, and therefore the cap 11 will not become flat due to vibration or impact. Since the cap 11 is not separated from the sealing part 2 and is directly fixed to the flat sealing part 2, the fixing structure of the cap 11 is simpler than the conventional one, and manufacturing is easy and inexpensive. Moreover, since a porcelain receiving part is not used, the mechanical strength is greater than that of the conventional one.
なお、偏平封着部両側面への溝の形成は、例え
ば、この溝と対応する形状に成形した偏平封着部
形成治具を用いれば、偏平封着部の形成と同時に
溝も形成することができる。 Note that the grooves can be formed on both sides of the flat sealing part by, for example, using a flat sealing part forming jig molded into a shape corresponding to the grooves, so that the grooves can be formed at the same time as forming the flat sealing part. I can do it.
次に、本考案の具体的な例を説明する。 Next, a specific example of the present invention will be explained.
バルブ１として石英ガラスを、口金１１として
E14／20を、接着剤１２として石粉と水ガラス等
を混ぜ合わせたもの（なお、これ自体を従来から
磁器製受部にバルブの偏平封着部を固着するのに
使用されてきたものと同じもの）をそれぞれ用い
て第１図および第３図に示す構造の100Wハロゲ
ン電球（本考案品）を製作し、その落下衝撃試験
をしたところ、偏平封着部の割れ等は発生せず、
加速度70G以上と良好な結果を示した。また、口
金にねじり力を加えて測定する口金接着強度試験
においても、3N・ｍ以上に十分耐えるという良
好な結果を示した。 The bulb 1 is made of quartz glass, and the cap 11 is made of quartz glass.
E14/20 is mixed with stone powder, water glass, etc. as the adhesive 12 (this is the same adhesive that has traditionally been used to fix the flat sealing part of the bulb to the porcelain receiver). When a 100W halogen light bulb (product of the present invention) with the structure shown in Figures 1 and 3 was manufactured using each of these lamps, and a drop impact test was performed, no cracks or the like occurred in the flat sealing part.
Good results were shown with an acceleration of over 70G. Furthermore, in the cap adhesion strength test, which is measured by applying twisting force to the cap, the product showed good results, being able to withstand more than 3Nm.
これに対して、バルブ、口金は上記と同じであ
つて、磁器製受部にバルブの偏平封着部端部を嵌

固着した従来例構造の100Wハロゲン電球（従来
品）においては、落下衝撃試験で加速度は50G以
下であり、また口金接着強度試験で2N・ｍとな
つていた。 On the other hand, the bulb and cap are the same as above, but the conventional example involves fitting the end of the flat sealing part of the bulb into the porcelain receiving part and fixing it with an adhesive made of a mixture of stone powder, water glass, etc. In a 100W halogen bulb (conventional product), the acceleration was less than 50G in a drop impact test, and 2Nm in a base bond strength test.
さらに、かかる本考案品においては、磁器製受
部の使用をなくすことができたことから、口金の
製作費用は従来品の磁器製受部を含めた口金費用
に比べて約1/5に削減することができた。 Furthermore, with this invented product, the use of the porcelain receiver can be eliminated, so the manufacturing cost of the cap is reduced to approximately 1/5 compared to the cost of the cap including the porcelain receiver of conventional products. We were able to.

Since the cap is fixed to the flat sealing portion by filling an adhesive between the cap and the flat sealing portion, there is no fear that the cap will separate from the flat sealing portion even if vibrations or shocks are applied. It is possible to improve mechanical strength such as impact resistance, and to provide a tube that is easy to manufacture and inexpensive due to the simplified structure.
