Transformer winding means and methods

In a transformer, a primary winding, a secondary winding, an iron core having spaced parallel portions, both said windings being mounted in inductive relationship with said iron core, said secondary winding being wound on a plurality of insulative bobbins apertured for receiving therein said core, each of said bobbins being formed with flanges at opposite ends to define a winding space for a portion of said secondary winding, each of said winding portions having a start end and a finish end, a first anchoring tab extending radially from the peripheral edge of one of said flanges of each of said bobbins and around which said start end of each of said winding portions is wrapped, a second anchoring tab extending radially from the peripheral edge of the other of said flanges of each of said bobbins and around which said finish end of each of said winding portions is wrapped, said bobbins and winding portions being mounted end to end in a pair of banks on said parallel iron core portions with said radial tabs in alignment, a first means for electrically connecting said finish ends and start ends on said adjacent second and first tabs so that said adjacent winding portions in each of said banks are connected in series, a second means for electrically connecting said finish end on said second tab of a last bobbin in one of said banks to said start end on said first tab of a first bobbin in the other of said banks so that said banks are connected in series, and a third means for electrically connecting said start end on said first tab of a first bobbin in said one of said banks to a secondary winding lead and for electrically connecting said finish end on said second tab of a last bobbin in said other of said banks to another secondary winding lead so that said banks are connected in series between said secondary leads.
