Low profile transformer bobbin

Claim 1

A transformer bobbin adapted for receiving at least one winding having a plurality of winding loops, comprising: a coil form for supporting said at least one winding thereon; an upper flange and a lower flange carried by opposite ends of the coil form for containing the winding on the coil form; a plurality of fingers formed in the lower flange, said fingers being defined by slots in the lower flange which extend to the periphery of the lower flange; and a terminal strip carried by the lower flange beneath said fingers, said terminal strip including a rear wall disposed in perpendicular relation to and extending between the distal ends of said lower flange, a plurality of spaced side walls each extending perpendicularly from said rear wall and aligned beneath a respective one of said slots, said rear and side walls dividing the strip into a plurality of electrically isolated terminal compartments, said compartments being spaced from said fingers by a channel extending between the distal ends of said lower flange such that each of said winding loops may be passed through a respective one of said slots and thence along said channel and into a different one of said compartments, said rear wall including a plurality of apertures each of which extends in spaced parallel relation beneath a respective one of said fingers such that each aperture communicates with one terminal compartment, whereby a tap lead may be fed into a compartment via one of said apertures for connection to a winding loop.
