Abstract:
A method of producing a connecting structure for covered wires, the method comprising:preparing a first covered wire having a first conductor covered with a first resinous cover and a second covered wire having a second conductor covered with a second resinous cover; overlaying the second covered wire on the first covered wire to cross each other; interposing respective overlapping portions of the first and second covered wires between an upper resin tip and a lower resin tip; oscillating the upper and lower resin tips with ultrasonic waves while compressing the upper and lower resin tips, whereby the first and second resinous covers of the first and second covered wires are molten for removal, thereby to bring the first conductor of the first covered wire into electrical contact with the second conductor of the second covered wire, and simultaneously, the upper and lower resin tips are mutually welded to each other thereby to seal up surroundings of a contact between the first conductor and the second conductor; and providing either one of the upper and lower resin tips, on its butt face being abutted against the other resin tip, with a stopper as a projection for defining a position of a leading end of the second covered wire interposed between the upper and lower resin tips, while the other of the upper and lower resin tips is provided, on its butt face being abutted against the other resin tip, with a recess for receiving the stopper.
