<p>PURPOSE: An electric heating device is provided to bend curve, and to improve a heat radiating performance, and to secure a strong binding power with an installation layer, and to obstruct moisture. CONSTITUTION: An electric heating device comprises a heating cable (1), two strands of electric wires having a different polarity (2), and a metal screw nail (3). The heating cable includes a conducting carbon heating element and a heating element insulating outer cover. The two strands of the electric wires having a different polarity are connected in parallel in order to input a power source into both ends of the heating cable. The metal screw nail is connected in each connection part of the wire and the heating cables. A connecting unit insulation cover (10) of a T shape is equipped in a connection part where the metal screw nail is connected.</p> |
