  • Method of forming inductor coils with mechanically coupleable bobbins
    Patent number: 4662572
    Abstract: An inductor coil comprises a main winding of insulated wire on the barrel of a bobbin having two axial lugs salient from one of the bobbin's end flanges, and having two recesses formed in the outer surface of the other of such flanges. A coaxial array of such bobbins is mounted on a rotatable spindle axially salient from a rotatable driving head such that the bobbins are, by such lugs and recesses, mechanically coupled together and to said head. The head is rotated to produce through such lugs and recesses a rotation of such bobbins utilized to form such main windings thereon. The lugs of each such bobbin supported elongated plastic arms having bifurcated outer ends around which are formed wire windings providing terminals for the main winding of the coil.
