[0052] figure 1 It is a schematic diagram showing the structure of a heater cable used in the circuit pattern of the present invention.

[0053] like figure 1 As shown, the structure of the heater cable 10 includes a core wire 1, a heating element wire 2 wound in a spiral shape on the outer surface of the core wire 1 at a given distance interval, and a heating element wire 2 arranged on the heating element A fuse layer 3 on the electric wire 2, a signal wire 4 wound in a spiral shape on the outer surface of the fuse layer 3, and a protective coating 5 provided on the signal wire 4.

[0054] The core wire 1 can be polyester fabric. The heating element wire 2 can be a flat square copper wire, a flat square copper alloy wire, a round copper wire or a round copper alloy wire. The fuse layer 3 can be made of nylon or polyester. The signal wire 4 can be a flat square copper wire, a flat square copper alloy wire, a round copper wire or a round copper alloy wire. This protectiv...

[0072] Now, in the circuit pattern of the present invention, an embodiment in which the fuse layer is made of copolymer polyester resin will be described. Note that the term "parts" in the following examples represents parts by weight.

[0073] Production of Copolymer Polyester Resin (A) for Experiment 1 Fused Layer

[0074]856 parts of acid groups of dimethyl terephthalate and 897 parts of 1,4-butanediol of diols, together with 0.37 parts of tetra-n-butyl titanate used as catalyst, were added with a Esterification was carried out at a temperature of 160°C to 210°C for 4 hours in a vessel with a stirrer, a thermometer and a distillation condenser. Then, 216 parts of ε-caprolactone of glycols and 1.08 parts of Irganox (a product of Ciba-Geigy Company) used as a stabilizer were added, and mixed at 220° C. for 30 minutes to 1 hour to stimulate further Reaction. After the pressure was reduced to 5 mmHg over the duration of 40 minutes while the reaction temperature was increased...

Abstract

A heater's cable integrated with leading cable is disclosed. Both cables form a pattern to separate one from another by a predefined distance. Said heater's cable has a core wire, a heating line wound around the core wire, a fusing layer on the heating line, a signal line wound around the fusing layer and a coated protecting layer on the signal line. Said leading cable is shielded by an insulative layer.

Description

technical field [0001] The present invention relates to a heater cable combined with a lead cable. More particularly, the present invention relates to a wiring pattern capable of minimizing a leakage magnetic field generated from the heater cable. Background technique [0002] A conventional sheet heating appliance, such as an electric blanket or heated carpet, is manufactured by combining a heater cable 40 and a sensor cable 50, which are routed in the carpet fabric material. For example Figure 15 As shown, the heater cable 40 includes: a heating element wire 32 spirally wound on the outer surface of a polyester core wire 31 at a given distance interval; A fuse layer 33 made of nylon or polyester; a short-circuit wire 34 wound into a spiral on the outer surface of the fuse layer 33; protective coating35. Additionally, if Figure 16 As shown, the sensor cable 50 includes: a signal wire 42 wound in a spiral shape on the outer surface of the polyester core wire 41; a fuse...
