従来の電熱線構造では、ニクロム線ヒーターの場合、サーモスタット、温度センサーが必要で消費電力が大きい、サーモスタット、温度センサーの故障で熱暴走の危険性がある。又、二本の平行した通電線を有機ヒーター材で一体化した構造の電熱線は、有機ヒーター材と通電線との密着性が割り事、断面積を大きくする事ができない事、可撓性に欠ける事、大電流容量に制限がある事、施工長さに制限があり、広大なヒーター敷設に対応出来ない事等の欠点があった。
本発明は、以下に述べる解決手段によって上述の問題を解決するものである。 In the conventional heating wire structure, a nichrome wire heater requires a thermostat and a temperature sensor and consumes a large amount of power. There is a risk of thermal runaway due to failure of the thermostat and temperature sensor. In addition, the heating wire with a structure in which two parallel energizing wires are integrated with an organic heater material has a problem in that the adhesion between the organic heater material and the energizing wire is critical and the cross-sectional area cannot be increased. There are drawbacks such as lack of power, restriction on large current capacity, restriction on construction length, and inability to handle large heater installation.
The present invention solves the above-mentioned problems by means of the solutions described below.

可撓性線材１２１、１３１を軸に、各その外周に編租導電線１２２、１３２を被覆した通電線１２、１３を並行に配設し、通電線１２、１３の上面を露出させるように、電気的絶縁機能を有する樹脂１１で一体樹脂成形した平角状線１を構成し、平角状線１の通電線１２、１３に自己温度制御機能を持つＰＴＣ発熱体２を結続するように塗布又は充填し、平角状線１及びＰＴＣ発熱体２を外皮３で覆った構造の手段。 With the flexible wires 121 and 131 as axes, the conductive wires 12 and 13 covering the outer periphery of the conductive wires 122 and 132 are arranged in parallel, and the upper surfaces of the conductive wires 12 and 13 are exposed. A flat wire 1 integrally molded with a resin 11 having an electrical insulating function is formed, and a PTC heating element 2 having a self-temperature control function is applied to the conducting wires 12 and 13 of the flat wire 1 so as to be connected or A means having a structure in which the flat wire 1 and the PTC heating element 2 are covered with an outer skin 3.
