る。(Problem to be Solved by the Invention) However, in the conventional lead wire connection structure shown in FIG. 2, an insulator 5 such as polyethylene or synthetic rubber is molded on the outside of the lead wire connection part. , because only taping was done around it, when force in the bending direction is applied to the connection part, the covering insulator 5 and vinyl tape 6 and the outer sheath 1 of the lead wire and coil side conductor, Cracks tend to occur at the joints between conductors 2 and 4, and water easily enters the interior through the cracks and reaches the joints between conductors 2 and 4, causing a drop in insulation. In particular, in the conventional connection structure for outgoing wires, the insulator 5 and the outer sheaths 1 and 3 are directly joined, and the interface between the two is uniformly structured, so that once a crack occurs, Creeping failure occurs due to the interface and insulation is damaged.
