られている。In order to eliminate this danger, there are products that use a single-wire heat-generating wire that is both a heat-generating wire and a temperature-sensitive wire. As shown in FIG. 3, this -wire type heat-generating temperature-sensitive line has a temperature-sensitive layer made of polyamide resin between the heat-generating line and the temperature-sensitive line. FIG. 3 is an explanatory diagram of a conventional single-wire heat-generating temperature-sensitive line. In the figure, 30 is a core yarn. A primary conductor 31, which is a temperature-sensitive wire, is wound around the surface of the core yarn 30 at a predetermined pitch. A temperature-sensitive layer 32 made of polyamide is provided on a core thread 30 around which a primary conductor 31 is wound. A secondary conductor 33, which is a heating wire, is wound on the temperature-sensitive layer 32 at a predetermined pitch.

が簡単で効率よく製品加工をすることができる。Further, a polyvinyl chloride sheath layer 35 is provided on the separator layer 34, and a fusion layer 36 made of polyethylene is provided on the polyvinyl chloride sheath layer 35. Here, the temperature-sensitive layer not only exhibits a temperature-sensing function, but also serves to melt and short-circuit the heat-generating wire and the temperature-sensitive wire when the temperature rises to a predetermined level or higher due to local overheating of the heat-generating wire. There are also products that use single-wire heat-generating temperature-sensitive wires that use polyvinyl chloride as the material for the temperature-sensitive layer. This -wire type heat-generating temperature-sensitive wire can be easily processed in wiring and terminal processing, which is performed in product processing of a two-wire type heat-generating temperature-sensitive wire, and can be processed efficiently.

しかしながら、ポリアミド系の感温層を設けた従来の一
線式発熱感温線は、ポリアミド系の樹脂が高い吸水性を
有するので、使用初期に加熱が遅いという欠点がある。[Problems to be Solved by the Invention] However, the conventional single-wire heat-generating temperature-sensitive wire provided with a polyamide-based temperature-sensitive layer has the drawback that heating is slow at the initial stage of use because the polyamide-based resin has high water absorption. There is.

線は、生産性、加工性、歩留りが悪い。On the other hand, the single-wire heat-generating temperature-sensitive wire with a polyvinyl chloride temperature-sensitive layer uses a carbonized short-circuit type, so the short-circuit temperature is not constant and it may not be possible to short-circuit at the desired temperature. It is insufficient in terms of safety. Furthermore, since polyvinyl chloride has poor thermal stability at high temperatures, the surface of the temperature-sensitive layer is burnt during extrusion processing for forming the temperature-sensitive layer. For this reason, the heat-generating temperature-sensitive wire provided with the temperature-sensitive layer of polyvinyl chloride has poor productivity, processability, and yield.

For example, the primary conductor is a temperature-sensing ground wire, the secondary conductor is a heating wire, and the tertiary conductor is a short-circuiting ground wire, or the primary conductor is a heating wire, the secondary conductor is a ground wire, and the tertiary conductor is short-circuiting.

る。[Function] The one-line heat-generating temperature-sensitive wire of the present invention uses three conductors to separately provide a temperature-sensing portion and a short-circuit portion. The temperature-sensing part consists of a temperature-sensing current-carrying wire, a ground wire, and a temperature-sensing layer provided between them. Of the current flowing through the temperature-sensing current-carrying wire, leakage current flows through the temperature-sensing layer and into the ground wire. Detect. Since the temperature-sensitive layer uses polyvinyl chloride-based thermistor resin with stable characteristic impedance, the resistance value changes sensitively depending on the ambient temperature. This changes the amount of leakage current flowing through the ground wire. The temperature is detected based on this change, and the amount of heat generated is adjusted by controlling the amount of current flowing through the heating wire.

In the short-circuit portion, when the temperature of the heating wire rises to an abnormal temperature due to local overheating of the heating wire, the shorting layer melts and short-circuits the ground wire and the heating wire. This prevents excessive heating of the heat-generating temperature-sensitive line.
