Title:
COIL AND METHOD FOR MANUFACTURING COIL
Document Type and Number:
WIPO Patent Application WO/2013/132900
Kind Code:
A1
Abstract:
In a coil material (1), a connection section (1c) connects one end of an annular section (1a) that has a missing part and one end of an annular section (1b) that has a smaller circumference than the circumference of the annular section (1a), and a protrusion (1d) protrudes outward from the annular section (1b). A coil member is configured by bending the connection section (1c) such that the annular sections (1a, 1b) overlap leaving a space therebetween. In a coil material (2), a connection section (2c) connects one end of an annular section (2a) that has substantially the same shape and size as the annular section (1a) and one end of an annular section (2b) that has a smaller circumference than the circumference of the annular section (2a), and a protrusion (2d) protrudes outward from the annular section (2b). A coil member is configured by bending the connection section (2c) such that the annular sections (2a, 2b) overlap leaving a space therebetween. A coil is formed by overlapping and connecting the protrusions (1d, 2d).
