  • Patent number: 6862800
    Abstract: A coated lead wire can be solidly connected to a terminal of a coil bobbin by placing the terminal entwined with the coated lead wire into between electrodes having heating portions, and supplying electric current to the electrodes to heat the terminal entwined with the coated lead wire along with solder to melt the solder and burn off a coating layer of the coated lead wire while exerting pressure against to the terminal entwined with the coated lead wire, and directing a blow of inert gas toward the terminal entwined with the coated lead wire between the electrodes. The coating layer carbonized as the result of being burned out by heating up the electrodes can be blown out without being mixed into the molten solder, consequently to add strength to the connection between the lead wire and the terminal, to thereby form a reliable and firm connection between the lead wire and the terminal with ease.
