しかしながら、固形カーボンを用いたものは可撓性がなく、直管以外の各種形状のヒーターランプを製作することができない問題があり、フェルト状カーボンを用いたものは繊維の密度が不均一であって、発熱分布が不均等となって正確な温度コントロールが困難であるほか、同一の仕様を有するものであっても、その特性について電力差が生じるなどの問題がある。  However, those using solid carbon are not flexible, and there is a problem that heater lamps of various shapes other than straight pipes cannot be manufactured. Those using felt-like carbon have non-uniform fiber density. As a result, heat distribution is uneven and accurate temperature control is difficult, and there is a problem that even if they have the same specifications, there is a power difference in their characteristics.

このような問題点に鑑みて、本出願人は炭素繊維糸を複数本撚り合わせてカーボン体とし、このカーボン体をコイル状に形成して発熱体を構成したヒーターランプを平成18年2月27日に特許出願した。本発明は、前記特許出願にかかるヒーターランプの端子の改良に関するもので、端子の取り付けが簡単で、しかも取り付けた端子はカーボンコイル体に確実に固定されるようにしたことを目的とする。  In view of such a problem, the present applicant twisted a plurality of carbon fiber yarns into a carbon body, and formed a heating element by forming the carbon body into a coil shape to form a heating element. The patent application was filed on the day. The present invention relates to an improvement of a terminal of a heater lamp according to the patent application, and an object of the present invention is to make it easy to attach the terminal and to securely fix the attached terminal to the carbon coil body.

上記のような目的を達成するために、本発明のヒーターランプは、石英ガラス管の内部に炭素繊維糸をコイル状に巻き上げてなるカーボンコイル体を配置したヒーターランプにおいて、前記カーボンコイル体の両端の直線部外周に帯状金属板を折り曲げ、押し潰して取り付けるとともに、前記帯状金属板の一部を直線状に延長して内部リード線との接続部を形成し、前記内部リード線をモリブデン箔を介して外部リード線に接続して端子を構成し、前記モリブデン箔の箇所にて前記石英ガラス管を加熱圧着して該石英ガラス管内に前記カーボンコイル体を封入するようにしたことを特徴とするものである。  In order to achieve the above object, the heater lamp of the present invention is a heater lamp in which a carbon coil body formed by winding a carbon fiber yarn in a coil shape is disposed inside a quartz glass tube, and both ends of the carbon coil body are arranged. A band-shaped metal plate is bent and crushed and attached to the outer periphery of the straight line portion, and a part of the band-shaped metal plate is linearly extended to form a connection portion with the internal lead wire, and the internal lead wire is made of molybdenum foil. A terminal is formed by connecting to an external lead wire, and the quartz glass tube is heated and pressure-bonded at the location of the molybdenum foil to enclose the carbon coil body in the quartz glass tube. Is.

また本発明のヒーターランプは、前記帯状金属板がカーボンコイル体と接する面に波状の凹凸部を形成したことを特徴とするものである。  The heater lamp of the present invention is characterized in that a corrugated uneven portion is formed on a surface of the belt-shaped metal plate in contact with the carbon coil body.

上記構成のヒーターランプによればカーボンコイル体の両端の直線部外周に帯状金属板を折り曲げ、押し潰して取り付けることで端子を構成し、しかもカーボンコイル体に接する帯状金属板の面に波状の凹凸部を形成したので、凸部がカーボンコイル体に食い込み、取り付けた端子はカーボンコイル体に確実に固定される。  According to the heater lamp having the above configuration, the band metal plate is bent on the outer periphery of the linear portion at both ends of the carbon coil body, and the terminal is configured by being crushed and attached to the surface of the band metal plate in contact with the carbon coil body. Since the portion is formed, the convex portion bites into the carbon coil body, and the attached terminal is securely fixed to the carbon coil body.

以下、図面を参照しながら、本発明に係る実施の形態について説明する。  Embodiments according to the present invention will be described below with reference to the drawings.

<イ>ヒーターランプ
ヒーターランプ1は、コイル状のカーボンコイル体(発熱体)2、左右の端子3及びこれらを封入する石英ガラス管4等で構成される(図1参照)。カーボンコイル体2は、炭素繊維撚糸20をコイル状に巻き上げたものである。炭素繊維撚糸20は、図4に示すように例えばポリアクリロニトリルを原料とするPAN系炭素繊維素線21を多数束ねて炭素繊維糸22とし、この炭素繊維糸22を複数本撚り合わせて構成される。
<A> Heater lamp The heater lamp 1 includes a coiled carbon coil body (heating element) 2, left and right terminals 3, and a quartz glass tube 4 enclosing them (see FIG. 1). The carbon coil body 2 is obtained by winding a carbon fiber twisted yarn 20 into a coil shape. As shown in FIG. 4, the carbon fiber twisted yarn 20 is formed by bundling a number of PAN-based carbon fiber strands 21 made of, for example, polyacrylonitrile as a carbon fiber yarn 22 and twisting a plurality of the carbon fiber yarns 22 together. .

<ロ>端子
端子3は、折り曲げ可能な導電性の帯状金属板30、帯状金属板30の一部と接続する内部リード線31、内部リード線31と外部リード線33とを接続するモリブデン箔32とで構成される(図1、図2参照)。帯状金属板30は、図3(B)に示すように両側の垂直部34、舌片36、波状の凹凸部37などが形成されている。
<B> Terminal The terminal 3 includes a bendable conductive strip metal plate 30, an internal lead wire 31 connected to a part of the strip metal plate 30, and a molybdenum foil 32 connecting the internal lead wire 31 and the external lead wire 33. (See FIGS. 1 and 2). As shown in FIG. 3B, the band-shaped metal plate 30 is formed with vertical portions 34, tongue pieces 36, wavy uneven portions 37, and the like on both sides.

この端子3をカーボンコイル体2に取り付けるには、先ず図3(A)に示すように帯状金属板30を例えばT字形に形成し、両側を垂直に折り曲げるとともに一部に切込み35を入れ、さらに波状の凹凸部37を形成しておく(図3(B))。垂直に折り曲げた箇所の底面38にカーボンコイル体2の直線部2aを載せ、波状凹凸部37がカーボンコイル体2の外周に接するように折り曲げていく(図3(B)、(C))。切込み35を入れたところを折り曲げることで舌片36が形成される。舌片36は特許請求範囲の接続部に相当する。そのまま波状凹凸部37をカーボンコイル体2に押し付けて凸部を食い込ませ、その上に両側の垂直折曲部34をさらに折り曲げながら押し付けて波状凹凸部37を確実にカーボンコイル体2に圧着させる。
その後、舌片36に内部リード線31をスポット溶接8し、内部リード線31の他端をモリブデン箔32にスポット溶接8し、モリブデン箔32に外部リード線33をスポット溶接8して内部リード線31と外部リード線33を接続する(図3(D))。
このようにしてカーボンコイル体2の一端に端子3が取り付けられた状態を図2に示す(図では内部リード線31、モリブデン箔32、外部リード線33の箇所で石英ガラス管4を押しつぶしてカーボンコイル体2を封入している)。この端子3をカーボンコイル体2の左右両端の直線部2aに取り付ける。
In order to attach the terminal 3 to the carbon coil body 2, first, as shown in FIG. 3A, a belt-like metal plate 30 is formed in, for example, a T shape, both sides are bent vertically and a cut 35 is made in a part thereof. A wave-shaped uneven portion 37 is formed (FIG. 3B). The straight portion 2a of the carbon coil body 2 is placed on the bottom surface 38 of the vertically bent portion, and is bent so that the wavy uneven portion 37 is in contact with the outer periphery of the carbon coil body 2 (FIGS. 3B and 3C). The tongue piece 36 is formed by bending the cut portion 35. The tongue piece 36 corresponds to a connecting portion in claims. The wavy uneven portion 37 is pressed against the carbon coil body 2 as it is to bite the convex portion, and the vertical bent portions 34 on both sides are further bent and pressed onto the carbon coil body 2 to securely press the wavy uneven portion 37 to the carbon coil body 2.
Thereafter, the internal lead wire 31 is spot welded 8 to the tongue piece 36, the other end of the internal lead wire 31 is spot welded 8 to the molybdenum foil 32, and the external lead wire 33 is spot welded 8 to the molybdenum foil 32 and the internal lead wire is connected. 31 and the external lead wire 33 are connected (FIG. 3D).
A state in which the terminal 3 is attached to one end of the carbon coil body 2 in this way is shown in FIG. 2 (in the figure, the quartz glass tube 4 is crushed at the locations of the internal lead wire 31, the molybdenum foil 32, and the external lead wire 33 to form carbon. The coil body 2 is enclosed). The terminals 3 are attached to the straight portions 2a at the left and right ends of the carbon coil body 2.

このような端子3の帯状金属板30は、プレス加工等で1枚の金属板から製作することができ、また本例のように切込み35を入れることによって、折り曲げたとき内部リード線31に接続するための舌片36が形成されるので便利である。  Such a band-like metal plate 30 of the terminal 3 can be manufactured from a single metal plate by pressing or the like, and is connected to the internal lead wire 31 when bent by making a notch 35 as in this example. This is convenient because a tongue piece 36 is formed.

<ハ>石英ガラス管
石英ガラス管4は、カーボンコイル体2を真空状態または不活性ガス雰囲気中で封入するための密閉容器である。石英ガラス管4は筒状に形成され、内部にカーボンコイル体2を収容するに十分な大きさとなっている。
カーボンコイル体2は、可撓性があって変形自在のため、石英ガラス管4の各種形状に沿って挿着することができ、例えば石英ガラス管4を折り曲げて環状(馬蹄形、楕円形、円形、オメガ形など)、コの字形などに屈曲させ、この屈曲した石英ガラス管4にカーボンコイル体2を挿着し、各種形状のヒーターランプ1を構成することができる。
<C> Quartz glass tube The quartz glass tube 4 is a sealed container for enclosing the carbon coil body 2 in a vacuum state or in an inert gas atmosphere. The quartz glass tube 4 is formed in a cylindrical shape and is large enough to accommodate the carbon coil body 2 therein.
Since the carbon coil body 2 is flexible and can be deformed, it can be inserted along various shapes of the quartz glass tube 4. For example, the quartz glass tube 4 is bent to form an annular shape (horse-shoe shape, elliptical shape, circular shape). , Omega type, etc.), and the carbon coil body 2 is inserted into the bent quartz glass tube 4 to form heater lamps 1 of various shapes.

<ニ>ヒーターランプの製造
先ず、炭素繊維糸22を複数本撚り合わせて炭素繊維撚糸20をつくり、これを液状樹脂等に浸して硬化させた後、コイリングし、所定のコイル径、コイル長を有するカーボンコイル体2をつくっておく。また、図3(B)に示すように折曲部34、切り込み35、舌片36、凹凸部37及び底面38を有する帯状金属板30をつくっておく。
前記したようにカーボンコイル体2の一端の直線部2aを底面38に載せ、凹凸部37がカーボンコイル体2を押し付けるように帯状金属板30を折り曲げ、さらに折曲部34を押し付けてカーボンコイル体2の一端に端子3を取り付ける。舌片36に内部リード線31の一端をスポット溶接8し、他端をモリブデン箔32にスポット溶接8し、モリブデン箔32に外部リード線33をスポット溶接8する。カーボンコイル体2の他端2aも同様にする。
<D> Manufacture of heater lamp First, a plurality of carbon fiber yarns 22 are twisted together to make carbon fiber twisted yarn 20, which is immersed in a liquid resin and cured, and then coiled to obtain a predetermined coil diameter and coil length. A carbon coil body 2 is prepared. Further, as shown in FIG. 3B, a band-shaped metal plate 30 having a bent portion 34, a cut 35, a tongue piece 36, an uneven portion 37 and a bottom surface 38 is prepared.
As described above, the linear portion 2 a at one end of the carbon coil body 2 is placed on the bottom surface 38, the band-shaped metal plate 30 is bent so that the concave and convex portion 37 presses the carbon coil body 2, and the bent portion 34 is further pressed to the carbon coil body. A terminal 3 is attached to one end of 2. One end of the internal lead wire 31 is spot-welded 8 to the tongue piece 36, the other end is spot-welded 8 to the molybdenum foil 32, and the external lead wire 33 is spot-welded 8 to the molybdenum foil 32. The same applies to the other end 2a of the carbon coil body 2.

このように左右両端に端子3を取り付けたカーボンコイル体2を、両端開きの石英ガラス管4内に挿入し、石英ガラス管4の両端を加熱プレスし、モリブデン箔32の箇所で圧着封止41する。
外部リード線33を碍子5を介して電気コード6に接続しながら、封止部41を碍子5の溝51に差し込んで(図5)、直管状のヒーターランプ1が製造される。なお図5ではモリブデン箔32、外部リード線33を省略している。内部リード線31と外部リード線33はモリブデン箔32の略中央に接続されているので、カーボンコイル体2と端子3とが中心軸上を一直線に並ぶように配置される。
カーボンコイル体2は、空気中で発熱させると燃えてしまうため、石英ガラス管4の内部を真空にした状態でカーボンコイル体2を収納するか、あるいは石英ガラス管4の内部を不活性ガスで置換する。
The carbon coil body 2 having the terminals 3 attached to the left and right ends as described above is inserted into the quartz glass tube 4 which is open at both ends, both ends of the quartz glass tube 4 are heated and pressed, and the pressure sealing 41 is performed at the location of the molybdenum foil 32. To do.
While connecting the external lead wire 33 to the electric cord 6 via the insulator 5, the sealing portion 41 is inserted into the groove 51 of the insulator 5 (FIG. 5), and the straight tubular heater lamp 1 is manufactured. In FIG. 5, the molybdenum foil 32 and the external lead wire 33 are omitted. Since the internal lead wire 31 and the external lead wire 33 are connected to the approximate center of the molybdenum foil 32, the carbon coil body 2 and the terminal 3 are arranged so as to be aligned on the central axis.
Since the carbon coil body 2 burns when it generates heat in the air, the carbon coil body 2 is accommodated in a state where the inside of the quartz glass tube 4 is evacuated, or the inside of the quartz glass tube 4 is filled with an inert gas. Replace.

<ホ>作用
この端子3を両端に取り付けたヒーターランプ1に通電すると、外部リード線33、モリブデン箔32、内部リード線31、舌片36、帯状金属板30を介してカーボンコイル体2に電流が流れ、カーボンコイル体2が発熱する。カーボンコイル体2が、炭素繊維糸22を複数本撚り合わせた撚糸よりなるため、カーボンコイル体2には電流が均一に流れ、その表面全域において均一に高い発熱効率が得られる。
<E> Action When the heater lamp 1 having both terminals 3 attached to both ends is energized, a current is supplied to the carbon coil body 2 via the external lead wire 33, the molybdenum foil 32, the internal lead wire 31, the tongue piece 36, and the belt-like metal plate 30. Flows and the carbon coil body 2 generates heat. Since the carbon coil body 2 is made of a twisted yarn in which a plurality of carbon fiber yarns 22 are twisted together, a current flows uniformly through the carbon coil body 2 and a high heat generation efficiency is obtained uniformly over the entire surface.

次に図6に基づき、本発明の他の実施形態を説明する。  Next, another embodiment of the present invention will be described with reference to FIG.

本例は、細長い棒状ガラス体7の表面にカーボンコイル体2を巻き付けて発熱体を形成し、その両端のカーボンコイル体2の直線部2aと棒状ガラス体7の小径部7aとを、前記と同様の手順でもって帯状金属板30で押圧し、前記したように凹凸部37がカーボンコイル体2の表面に食い込むようにして端子3を構成している。
このように左右両端に端子3を取り付けた発熱体を、両端開きの石英ガラス管4内に挿入し、モリブデン箔32の箇所で石英ガラス管4を加熱圧着41し、カーボンコイル体2を内蔵したヒーターランプ1を製造する。
棒状ガラス体7を用いた場合は、カーボンコイル体2を石英ガラス管4の中心に配置することができ、カーボンコイル体2が石英ガラス管4の内側に接触したりして石英ガラス管4の温度が局部的に上昇するなどの問題がない。
In this example, the carbon coil body 2 is wound around the surface of the elongated rod-shaped glass body 7 to form a heating element. The terminal 3 is configured in such a manner that it is pressed by the belt-shaped metal plate 30 in the same procedure, and the uneven portion 37 bites into the surface of the carbon coil body 2 as described above.
