Description of the Related Art Conventionally, a conductor connection between magnet wires of an electric motor or between a magnet wire and a lead wire has been performed by a method such as soldering, pressure welding with a crimping sleeve, or welding of a joint. However, it was not possible to guarantee stable and reliable work, and variations in the finished quality could not be avoided. When using soldering or pressure welding with a crimping sleeve, removal of the insulating coating on the magnet wire is a problem.Because it is necessary to remove the insulating coating by scraping it off or dissolving it with an organic solvent, it takes skill and time to remove it, and it can be reliably removed. If it is not, there is a problem of poor continuity, and the insulation film can be burned off by welding, but if the magnet wire is thin, the magnet wire will be cut off, or the welded part will be oxidized and the bonding will be incomplete. Is causing problems.
