NON-MAGNETIC FIELD HEATING WIRE FOR BEDDING OR THE LIKE, CAPABLE OF REDUCING MANUFACTURING COSTS BY ELIMINATING NECESSITY OF USING INSULATION LAYER FOR PREVENTING SHORT CIRCUIT BETWEEN HEATER COILS

摘要

PURPOSE: A non-magnetic field heating wire is provided to effectively prevent a short circuit, and reduce costs by eliminating the necessity of using an expensive material including Teflon or glass fiber insulator. CONSTITUTION: A non-magnetic field heating wire comprises core thread(1); two strands of heater coils(2,3) wound in parallel with each other along the outer surface of the core thread; and an external insulator(6) coated on the surface of the core thread so as to insulate the heater coils. The heater coils have electrically connected ends and the other ends connected to the respective positive and negative terminals of a power source.
