Abstract

A multi-turn electrical coil and fabrication method uses a plurality of identically constructed flat electrical conductors, alternating ones of which carry an electrically insulating material layer on one major surface. The bare conductors and the insulated conductors are alternatingly stacked about mounting posts in partially overlapped and partially laterally offset pairs of conductors, with each conductor in each conductor pair reoriented relative to the other conductor in the respective conductive pair, and alternating conductor pairs reoriented relative to adjacent conductor pairs, to form a spiral winding turn for the coil.

First claim

What is claimed is:

1. A coil for an electrical and/or electronic apparatus comprising:
a plurality of vertically stacked electrical conductors, each having a linear shape, the plurality of electrical conductors arranged in conductor pairs in a spiral coil configuration;
each conductor pair including a first conductor and a second conductor, the second conductor having an electrically insulating material layer on one major surface;
the first and second conductors inverted rela…
