ABSTRACT:
Improved multi-sectional bobbin designs described herein define a channel suitable to accommodate a portion of the wire that transits from prior winding section to the next, wherein opposing walls of the channel so defined separate the transiting portion of the wire from both prior and next winding sections through a substantial entirety of the wires descent from an upper winding layer in the prior section to a lower winding layer in the next.
