Abstract | PURPOSE:To obtain a coil in which the insulating distance of a leading-out line is ensured, by forming a protrusion for leading-out in a first layer winding to a secondary side coil bobbin in an alignment winding for a transformer and accurately positioning the first layer winding at the specified position of the secondary side coil bobbin. CONSTITUTION:The winding-start and winding-end of a first layer winding 3A directly wound on the outer circumferential surface of a cylindrical section 1b for a secondary side coil bobbin 1 are engaged with protrusions 2 and the winding 3A is led out to both end sides, and the leading-out lines 5 are positioned by the protrusions 2, and led out to the outside at precise positions. Consequently, when a second layer winding 3B is wound on a film 4A, the film 4A on the lower side is not displaced in the circumferential direction and a space between each leading-out line of the first layer winding 3A and the second layer winding 3B is held, thus ensuring an insulating distance. The subsequent relationship of the films and windings is not also displaced, thus securing each insulating distance. |
