<p>PROBLEM TO BE SOLVED: To provide an electric fusing coupling which generates no short circuit by the contact in two resistant line coils owing to the flow of a molten resin, when it is melted and connected to a resin pipe. SOLUTION: While the end of a resin pipe is made possible to fit to the cylindrical inner peripheral surface, a resistant line heated by carrying the current is buried in a coil form in an electric fusing coupling 10. In this case, one side winding diameter is provided larger than the other side in either one side or the both sides at the end of the resistant line coil 12, and the winding interval with a neighboring resistant line coil 12b is provided larger than the other part.</p> |
