Abstract

PROBLEM TO BE SOLVED: To solve such a problem that, while the occurrence of fluffing and fly is prevented by bundling with a thin metallic wire and binding with an insulator in a conventional carbon fiber heating wire, the value of resistance is high (10 Ω/1 m), so that an application of high voltage is required in warming.SOLUTION: In a carbon fiber heating wire, a pitch-based carbon fiber is used, and a heat insulation layer is further formed, using an aramid fiber, to the carbon fibers which are formed by overlapping a plurality of carbon fibers without twisting and damaging and coated with vinyl chloride so as not to be cut, and a crimping terminal is wound without being crushed to be connected to a wire with pressure. The temperature of a heating wire rise fast and which is capable of being used to high temperatures can be provided using the carbon fiber heating wire.SELECTED DRAWING: Figure 2

Description

省電力で発熱する、炭素繊維発熱線に関する。     It relates to a carbon fiber heating wire that generates heat with power saving.

従来から炭素繊維の発熱線を製作するとき、電線を製作する押出被覆工程機械を使用することが知られています、炭素繊維は細く、しかも破断伸びが小さい（高々2 ％）ので、複数本縒ったりすることでフライや粉塵となり大気中に飛散し易い、これを防止するため金属細線(例えば、特許文献１参照）また強化繊維（特許文献２参照）で束ねる等の方法をとっている。  Conventionally, when producing carbon fiber heating wires, it is known to use an extrusion coating machine that produces electric wires. Since carbon fibers are thin and have a small elongation at break (at most 2%), multiple wires In order to prevent this, it takes a method such as bundling with fine metal wires (see, for example, Patent Document 1) or reinforcing fibers (see, Patent Document 2).

以上述べたように発熱線に炭素繊維を使う理由は少ない電力で発熱することであるが製作するときに電線押出機を使うため破断したり毛羽となりフライは電線押出機の電気回路に入り短絡することがある。  As described above, the reason for using carbon fiber for the heating wire is to generate heat with a small amount of power, but because the wire extruder is used when manufacturing, it breaks or becomes fluff and the fly enters the electrical circuit of the wire extruder and shorts out Sometimes.

本発明は、このような従来の構成が有した問題を解決使用としたものであり炭素繊維から発熱する電力を少なくて高温になることを目的とした物である。  The present invention is intended to solve such problems of the conventional configuration and to increase the temperature by reducing the electric power generated from the carbon fiber.

電線押出機を使うにあたり、トウ（長繊維）を２段重ねにするトウは出荷されるときサイジング剤が塗布され形状は整っていることと、押出機で毛羽など出さずに被覆することができ,少ない電力で発熱する発熱線を提供できる。  When using a wire extruder, a tow with two layers of tows (long fibers) is coated with a sizing agent when shipped, and can be covered without fluffing with the extruder. Therefore, a heating wire that generates heat with less power can be provided.

以下、本発明の実施形態を図1〜図6基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図においては、１は炭素繊維発熱線の発熱する部分で２、は圧着端子に熱収縮チューブで絶縁し3、の通電線に接続し電流を流している。  In the figure, 1 is a portion of the carbon fiber heating wire that generates heat, 2 is insulated from the crimp terminal by a heat-shrinkable tube, and is connected to a current-carrying wire of 3 to pass a current.

A-A1の断面は４炭素繊維（トウ）を平行に傷をつけずに５塩化ビニール系の軟らかい被覆で覆いA-A2の断面のように、６パラ系アラミド繊維で断熱層を形成し７のフッ素、シリコン系樹脂で覆う。 The cross section of A-A1 covers 4 carbon fibers (tow) with a soft polyvinyl chloride coating without damaging them in parallel. A cross section of A-A2 forms a heat insulation layer with 6 para-aramid fibers. Cover with fluorine or silicon resin.

４，５の炭素繊維を電線の中心に空間を設け電線の中心に炭素繊維を差込、６パラ系アラミド繊維は３の銅線と４，５のアラミド繊維と分離してハサミで切断する。   A space is provided in the center of the wire for the 4 and 5 carbon fibers, the carbon fiber is inserted in the center of the wire, and the 6 para-aramid fibers are separated from the 3 copper wires and the 4 and 5 aramid fibers and cut with scissors.

９の圧着端子は市販品とは違い、フッ素系、シリコン系樹脂も含めて纏める方式で11を固定し、10を巻き閉める。  The 9 crimp terminals are different from commercial products, and 11 is fixed by a method that includes fluorine-based and silicon-based resins, and 10 is closed.

本発明は炭素繊維をサイジング剤が塗布された状態で平行に重ね合わせ傷をつけず、毛羽、フライなど粉塵を大気中に出さずにビニール被覆してしまい図１に示すように、発熱線を電線と接続する端子と熱収縮チュウブで構成された炭素繊維発熱線である。  In the present invention, carbon fibers are coated in parallel with a sizing agent applied, and are not damaged, and are covered with vinyl without releasing dust such as fluff and fly into the atmosphere. As shown in FIG. It is a carbon fiber heating wire composed of a terminal connected to an electric wire and a heat-shrinkable tube.

実施例について説明する、図２A-A1断面は炭素繊維トウを平行に重ね縒らずに塩化ビニールで被覆し、図３A-A2断面図のように炭素繊維を塩化ビニール被覆したものに、自己消火があるパラ系アラミド繊維で断熱層を作り、フッ素系、シリコン系樹脂で被覆する、図４で炭素繊維と電線を接続する時に電線の中に、炭素繊維を挿入し折れない胴で保護し、圧着端子をつぶすさずに巻きつける様に閉める。  Fig. 2A-A1 is a cross section of carbon fiber tow covered in parallel with vinyl chloride without overlapping the carbon fiber tow, and carbon fiber is coated with vinyl chloride as shown in Fig. 3A-A2. Make a heat insulation layer with a certain para-aramid fiber, and cover it with fluorine-based or silicon-based resin. When connecting the carbon fiber and the wire in Fig. 4, the carbon fiber is inserted into the wire to protect it with an unbreakable body. Close the crimp terminal so that it wraps without crushing.

本実施例は炭素繊維を縒りをかけず、毛羽を極力少なくしたためと電線を接続する際、銅の中に炭素繊維が入るため電流が安定して供給できる従って省電力で温度の立ち上がりが早く、高温まで対応できる発熱線できる。  In this example, the carbon fiber is not sprinkled, and when connecting the electric wire because the fluff is reduced as much as possible, the carbon fiber enters the copper, so that the current can be stably supplied. A heating wire that can handle high temperatures.
