Description

この発明は、ベース付きフィラメントランプに関するものであり、特に、ベースをセメント等の接着剤を用いることなくフィラメントランプに固定してなるベース付きフィラメントランプに係わるものである。   The present invention relates to a filament lamp with a base, and more particularly to a filament lamp with a base formed by fixing the base to the filament lamp without using an adhesive such as cement.

従来、複写機、レーザービームプリンタなどの画像固定装置のトナー定着用加熱光源として用いられるフィラメントランプにおいては、その両端の封止部内の金属箔に、フィラメントの両端の内部リードと、発光管外に導出される外部リードとを接続してピンチシールするものが一般に多用されていた。
このようなフィラメントランプは、通常その両端のピンチシール部にベースを取り付けて使用されるが、このベースをセメント等の接着剤を用いることなく取り付ける構造のものが知られている。例えば、実用新案登録第２５７９０４２号公報（特許文献１）などがこれである。 Conventionally, in a filament lamp used as a heating light source for fixing toner in an image fixing apparatus such as a copying machine or a laser beam printer, a metal foil in a sealing portion at both ends, an internal lead at both ends of the filament, and an outside of the arc tube In general, a pinch seal is connected to the lead-out external lead.
Such a filament lamp is usually used with a base attached to pinch seal portions at both ends thereof, and a structure in which this base is attached without using an adhesive such as cement is known. For example, this is Utility Model Registration No. 2579042 (Patent Document 1).

図６にその構造が示されている。
フィラメントランプ３０は、石英ガラスからなる長尺な発光管３１の両端にピンチシールからなる封止部３２が形成されており、その発光管３１内部にはフィラメント３３が管軸と一致するように配置されている。そして、前記発光管３１の両端の封止部３２内には、図示しない金属箔が埋設されていて、前記フィラメント３３の内部リード３４と、発光管外部に導出された外部リード３５とが、それぞれ溶接等により接続されている。
そして、前記封止部３２には、ベース３６が嵌合されている。このベースは、例えばセラミックよりなる略円筒形状体であり、一端側に封止部３２が挿入される第１の開口３７が、他端側に給電線４２が挿入される第２の開口３８が形成されている。
その中央部には、溶接作業孔３９が形成されており、該溶接作業孔３９は第２開口３８と連通している。また、該溶接作業孔３９と前記第１開口３７との間には隔壁４０が形成され、該隔壁４０には外部リード挿通口４１が形成されている。 FIG. 6 shows the structure.
The filament lamp 30 is formed with a sealing portion 32 made of a pinch seal at both ends of a long arc tube 31 made of quartz glass, and the filament 33 is arranged inside the arc tube 31 so as to coincide with the tube axis. Has been. A metal foil (not shown) is embedded in the sealing portions 32 at both ends of the arc tube 31, and an internal lead 34 of the filament 33 and an external lead 35 led out of the arc tube are respectively provided. Connected by welding or the like.
A base 36 is fitted into the sealing portion 32. The base is a substantially cylindrical body made of, for example, ceramic, and has a first opening 37 into which the sealing portion 32 is inserted at one end side and a second opening 38 into which the power supply line 42 is inserted into the other end side. Is formed.
A welding work hole 39 is formed at the center thereof, and the welding work hole 39 communicates with the second opening 38. Further, a partition wall 40 is formed between the welding work hole 39 and the first opening 37, and an external lead insertion port 41 is formed in the partition wall 40.

フィラメントランプ３０の封止部３２はベース３６の第１開口３７に挿入され、このとき、封止部３２から外部に導出された外部リード３５は前記外部リード挿通口４１を貫通して溶接作業孔３９内にまで突出する。
一方、給電線４２の先端には端子４３が、圧着や溶接などの手段によって固着されていて、この給電線４２が第２開口３８に挿入されると、その先端の端子４３は前記溶接作業孔３９内に位置し、ここで前記外部リード３５と重なり合う位置関係になる。
そして、該溶接作業孔３９を介して適宜の溶接具により、外部リード３５と前記端子４３とが溶接されるものである。
このとき、封止部３２と端子４３は、隔壁４０を両側から挟さむように固定され、これによりベース３６が封止部３２に対して固定される。 The sealing portion 32 of the filament lamp 30 is inserted into the first opening 37 of the base 36. At this time, the external lead 35 led out from the sealing portion 32 penetrates the external lead insertion port 41 and is a welding work hole. It protrudes into 39.
On the other hand, a terminal 43 is fixed to the tip of the power supply line 42 by means such as crimping or welding, and when the power supply line 42 is inserted into the second opening 38, the terminal 43 at the tip of the terminal 43 is connected to the welding work hole. 39, where the external leads 35 overlap with each other.
The external lead 35 and the terminal 43 are welded by an appropriate welding tool through the welding work hole 39.
At this time, the sealing portion 32 and the terminal 43 are fixed so as to sandwich the partition wall 40 from both sides, whereby the base 36 is fixed to the sealing portion 32.

ところで、このような従来技術においては、ランプ３０と給電線４２とをベース３６内に挿入した後に、給電線４２に固着された給電端子４３に外部リード３５を溶接作業孔３９を介して溶接するものであるので、その作業が限定された箇所での作業となり、非常に煩雑であり、組立て作業が非効率となっていた。
また、ベースには溶接作業のために所定の大きさの溶接作業孔を設ける必要があり、その分だけベースの大きさも大型化していた。 By the way, in such a conventional technique, after the lamp 30 and the power supply line 42 are inserted into the base 36, the external lead 35 is welded to the power supply terminal 43 fixed to the power supply line 42 through the welding work hole 39. Therefore, the work becomes a work in a limited place, which is very complicated and the assembly work is inefficient.
Further, it is necessary to provide a welding work hole of a predetermined size for the welding work, and the size of the base is increased accordingly.

図において、フィラメントランプ１の封止部２内には金属箔３が埋設されており、該金属箔３には外部リード４が溶接等により電気的に接続されていて、該外部リード４は封止部２の外部に突出している。
そして、該外部リード４は、給電線５とともに、詳細を後述する給電端子６に溶接等により接続されている。また、同様に後述するように、該給電端子６にはバネ部材７が設けられている。
また、前記封止部２には、セラミック等よりなるベース１０が嵌合されていて、該ベース１０には、前記封止部２が挿入される第１開口１１と、前記給電線５が挿入される第２開口１２が形成され、これらの開口１１、１２の間には隔壁１３が設けられていて、該隔壁１３には連通口１４が形成されている。該連通口１４は前記給電端子６が通過できる開口径を有している。 1A and 1B are cross-sectional views of an end portion of a filament lamp with a base according to the present invention, in which FIG. 1A is an assembly explanatory view and FIG. 1B is a completed view.

The external lead 4 is connected to the power supply terminal 6, which will be described in detail later, together with the power supply line 5 by welding or the like. Similarly, as will be described later, the power supply terminal 6 is provided with a spring member 7.
Further, a base 10 made of ceramic or the like is fitted into the sealing portion 2, and the first opening 11 into which the sealing portion 2 is inserted and the feeder 5 are inserted into the base 10. A second opening 12 is formed, a partition wall 13 is provided between the openings 11 and 12, and a communication port 14 is formed in the partition wall 13. The communication port 14 has an opening diameter through which the power supply terminal 6 can pass.

前記給電端子６の詳細構造が図２〜図４に示されている。
図２において、給電端子６は、本体６ａの側面にバネ部材７が設けられていて、該バネ部材７は、給電線側の一端７ａが本体６ａに溶接等により固着されており、外部リード側の他端７ｂ側は外方に拡開している。即ち、該バネ部材７は、内方に向けた外力が付与されると内方に向けて弾性変形して、外力が解除されると外方に向けて復元するものである。
なお、前記バネ部材７は給電端子６と一体に形成されたものであってもよく、その場合は、適宜の曲げ加工、切断加工、切り離し加工などによって形成できる。 The detailed structure of the power feeding terminal 6 is shown in FIGS.

また、図４は、給電端子６のみを表す正面図（Ａ）と左側面図（Ｂ）である。 FIG. 3 is a plan view showing a state where the external lead 4 of the lamp and the power supply line 5 are connected to the power supply terminal 6 by welding or the like.
FIG. 4 is a front view (A) and a left side view (B) showing only the power supply terminal 6.

上記構成において、再び図１を参照して組み立て方法を説明する。
まず、図１（Ａ）において、給電線５にベース１０を被嵌させて、給電線５の先端がベース１０の外に出るように該ベース１０を後退位置（図の右方側）に移動する。
その状態で、給電線５を給電端子６の一端側に溶接等により接続するとともに、該給電端子６の他端側にはランプ１の外部リード４を同様に溶接等により接続する。
次いで、前記ベース１０を矢印Ｘのように移動させる。給電端子６が隔壁１２の連通口１３を通過するとき、バネ部材７は内方に向けて変形し、給電端子６の通過に支障はない。
そして、図１（Ｂ）に示すように、給電端子６のバネ部材７が前記連通口１３を通過すると、該バネ部材７は弾性力により復元して再び拡開し、その先端が隔壁１３に当接する。
これにより、バネ部材７と封止部３とで隔壁１３を両側から挟持するようになるので、ベース１０はランプ１に対して固定される。 In the above configuration, the assembly method will be described with reference to FIG. 1 again.
First, in FIG. 1A, the base 10 is fitted on the power supply line 5, and the base 10 is moved to the retracted position (right side in the figure) so that the tip of the power supply line 5 comes out of the base 10. To do.
In this state, the power supply line 5 is connected to one end side of the power supply terminal 6 by welding or the like, and the external lead 4 of the lamp 1 is similarly connected to the other end side of the power supply terminal 6 by welding or the like.
Next, the base 10 is moved as indicated by an arrow X. When the power supply terminal 6 passes through the communication port 13 of the partition wall 12, the spring member 7 is deformed inward and there is no hindrance to the passage of the power supply terminal 6.
Then, as shown in FIG. 1B, when the spring member 7 of the power supply terminal 6 passes through the communication port 13, the spring member 7 is restored by elastic force and expanded again, and the tip thereof becomes the partition wall 13. Abut.
As a result, the partition wall 13 is sandwiched between the spring member 7 and the sealing portion 3 from both sides, so that the base 10 is fixed to the lamp 1.

図５に他の実施例が示されている。
図において、外部リード４には、封止部４の端部から間隙を設けて、例えば、金属製の位置決め部材１５が取り付けられている。その他の構成は前記図１の実施例と同様である。
この実施例では、該位置決め部材１５と前記バネ部材７とによって隔壁１３を挟持するものである。
図１の実施例の場合は、ガラス製である封止部２の端部が隔壁１３に当接するので、ベース１０を含めたランプ１の長さ方向の寸法がガラスの製造精度に依存することになるのに対して、この実施例では、位置決め部材１５によってその寸法精度が向上する。 Another embodiment is shown in FIG.
In the figure, for example, a metal positioning member 15 is attached to the external lead 4 with a gap provided from the end of the sealing portion 4. Other configurations are the same as those of the embodiment of FIG.
In this embodiment, the partition wall 13 is sandwiched between the positioning member 15 and the spring member 7.
In the case of the embodiment of FIG. 1, since the end of the sealing portion 2 made of glass contacts the partition wall 13, the lengthwise dimension of the lamp 1 including the base 10 depends on the glass manufacturing accuracy. In contrast, in this embodiment, the positioning member 15 improves the dimensional accuracy.

上記のように、本発明においては、フィラメントランプの封止部に嵌合されたベースに、封止部が挿入される第１開口と、給電線が挿入される第２開口を形成し、これらの間に、連通口を有する隔壁を形成し、外部リードと給電線が給電端子を介して接続され、該給電端子にはバネ部材を設け、該バネ部材が前記連通口を第１開口から第２開口方向には弾性変形して通過可能であり、第２開口から第１開口方向には通過不能であるようにしたので、給電端子に対する外部リードおよび給電線の接続をベースの外部で行うことができ、その作業が簡略化される。
そして、給電端子への外部リードおよび給電線の接続後に、ベースを単に給電線に沿わせて移動するだけで、該ベースをランプに対して容易に固定することができる。
また、ベースには溶接作業孔がないので、ベース全体の小型化が図られる。
更には、外部リードに位置決め部材を取り付けることにより、ベースを含めたランプ全長の寸法精度が向上する。 As described above, in the present invention, the first opening into which the sealing portion is inserted and the second opening into which the feeder line is inserted are formed in the base fitted to the sealing portion of the filament lamp. A partition wall having a communication port is formed between the external lead and the power supply line via a power supply terminal, a spring member is provided on the power supply terminal, and the spring member connects the communication port through the first opening. Since it is allowed to pass elastically deformed in the direction of the two openings and cannot pass from the second opening to the direction of the first opening, the external lead and the power supply line are connected to the power supply terminal outside the base. And the work is simplified.
Then, after the external lead and the power supply line are connected to the power supply terminal, the base can be easily fixed to the lamp by simply moving the base along the power supply line.
Further, since the base does not have a welding work hole, the entire base can be reduced in size.
Furthermore, by attaching a positioning member to the external lead, the dimensional accuracy of the entire lamp length including the base is improved.
