<p><P>PROBLEM TO BE SOLVED: To provide a transformer that securely ensures insulation between a plurality of secondary windings that can be automatically wound by a machine and have mutually individual independent outputs. <P>SOLUTION: A bobbin has an inward cylindrical portion which is made of insulating resin in a nearly cylindrical shape and has terminal blocks at both axial ends thereof, and an outward cylindrical portion 31 which is made of insulating resin and externally covers the inward cylindrical portion. The outward cylindrical portion 31 is in such a half-cut shape cut with division planes 31-1A and 31-2A which are parallel with an inward mounting substrate opposite surface and an inward mounting substrate anti-opposite surface of the inward cylindrical portion and extend almost in directions wherein respective adjacent sections are connected. The division planes 31-1A and 31-2A are in a rectangular wave shape, more specifically, in a zigzag shape to be in a staircase shape at positions of respective partition walls. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
