<p>PURPOSE:To facilitate bending a winding at right angles and holding the winding while stabilizing characteristics, by projecting and forming a stretching winding section from the surface of an insulating film to a winding-start section and a winding-end section of the winding and providing a guide face inclined to the winding side. CONSTITUTION:A stretching winding section 11 is formed by a rising edge section projected from the surface of an insulating film 8 to the periphery of a small circular hole 10, and a peripheral surface thereof is shaped in a guide face 12 on which a terminal section 6 for a winding 3 is stretched and wound. The guide face 12 is inclined to the winding 3 side. The stretched and wound terminal section 6 is inhibited by a section tilted to the winding side and spread to the outside, and does not slip off. Since the guide face 12 takes an arcuate shape, it can guide the winding 3 smoothly. Consequently, the terminal section 6 for the winding in a coil is bent at a right angle and the winding is held positively, thus stabilizing characteristics, then easily automating the formation of the multilayer coil. There is no possibility in which the damage of an insulating film at the bending section at the right angle and the damage of the winding are generated.</p> |
