Coil for electrical and electronic equipment as well as process for production thereof
First Claim
1. A coil for electrical and electronic equipment, comprising:
- a spiral conductor coil prepared by disposing coaxially a plurality of conductors each having a flat circular arc-shaped configuration in multiple stages along a vertical direction, and linking sequentially ends of said conductors to each other by means of linking members in the vertical direction; and
an insulating layer covering the surface of said conductor coil.

Abstract
A coil for electrical and electronic equipment comprises a spiral conductor coil 2 prepared by disposing coaxially a plurality of conductors 4a through 4d each having a flat circular arc-shaped configuration in multiple stages along a vertical direction, and linking sequentially ends of these conductors 4a through 4d to each other by means of linking members 5a through 5c in the vertical direction; and an insulating layer 3 covering the surface of the conductor coil 2, so that a relationship between a conductor width and a coil core diameter does not depend mutually, it becomes possible to increase and decrease optionally the conductor width and the coil core diameter, and as a result, a wider conductor width and a smaller coil core diameter in the conductor coil 2 than that of a conventional coil can be achieved.

7. A process for the production of a coil for electrical and electronic equipment, comprising the steps of:
-
forming a conductor plate prepared by linking sequentially ends of a plurality of conductors each having a flat circular arc-shaped or a polygonal configuration to each other;
said plurality of conductors being obtained by pressing or etching metallic plates;
covering the surf ace of said conductor plate with an insulating layer; and
thenfolding alternately said respective conductors at each linked portion of said conductors in said conductor plate so as to overlap coaxially said conductors thereby forming a substantially spiral conductive coil.
