Multi-turn electrical coil and fabricating device and associated methods

摘要

A coil former provides for restricted cross-over locations for a coil resulting in an optimum wire packing at all points within the coil. The coil former has a first side wall in a spaced relation to an opposing second side wall, wherein a cavity formed between the side walls accommodates multiple turns of wire for forming a coil. A block is fixed between the opposing first and second side walls and has its peripheral wall surface tapered from the first wall surface inwardly toward the opposing second wall surface for preferentially receiving and positioning turns of wire forming the coil.

1. A coil former comprising:
a first side wall in spaced relation to an opposing second side wall, wherein a cavity is formed therebetween and dimensioned for receiving multiple turns of wire for forming a coil therein; and a block fixed between the opposing first and second side walls, wherein a peripheral wall surface of the block is tapered from the first side wall to the opposing second side wall, and wherein at least one of the first and second side walls includes a channel formed outwardly from the tapered surface to provide an area of greater spacing than the spaced relation, the area of greater spacing sufficient for accommodating a cross-over portion of a coil formed within the cavity.
