Abstract
Abstract There is provided a method of fabricating a coil and in particular to one including the steps of forming a frame with two vertically disposed supporting legs, mounting an axial coil and notches on the supporting legs, cutting off the conducting wire from two ends of the ferrite core of the coil, joining the conducting wire to the two ends of the ferrite core, enclosing the combined coil and the supporting legs with resin, and bending the lower part of the supporting leg upwardly along the outer surface of the coil.

Claim 1
Independent Claim
153 words
A method of fabricating a coil comprising the steps of: forming a frame having a pair of opposingly displaced vertically disposed supporting legs each of said supporting legs having a notch formed within an upper portion thereof; mounting an axial coil, said axial coil having a ferrite core and an electrically conducting wire extending along a center line of the ferrite core, said electrically conducting wire extending from opposing axial ends of said ferrite core between said supporting legs by placing said wire in said notches; severing opposing ends of said conducting wire extending beyond said notches; joining the conducting wire to said axial ends of the ferrite core; encapsulating the combined supporting legs and the axial coil with resin thereby forming an enclosed structure; and, bending a lower part of each supporting leg upwardly along a respective outer surface of said structure thereby forming electrodes at the respective ends of the coil.
