Abstract
A high current capacity electrical coil made of coil elements stamped out from a plate or sheet of conductive material with mating male and female formations at opposite ends so that the male and female formations of adjacent elements can be fitted together and fusion bonded to form a helix. The latter is coated by powder coating techniques to insulate the coil.
Claims11
A heavy duty electrical coil comprising:
- a multiplicity of identical elongated electrically conductive elements stamped from at least one plate of electrically conductive material and with each of said elements having a male formation projecting beyond an edge of the respective element at one end and a female formation in the form of a cutout complementary to said male formation and opening at an edge of an opposite end of the respective element, the male formations of said elements fitting into the female formations of adjoining elements to form respective joints between adjoining elements at which broad surfaces of said adjoining elements are substantially flush with one another, thereby forming successive turns of a helix;
- and
- means for fusion bonding each male formation of a respective joint to the adjoining element receiving same, thereby producing said coil.
