Title:
BOBBIN-LESS COIL AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/075464
Kind Code:
A1
Abstract:
A bobbin-less coil and a method of manufacturing the bobbin-less coil. In the method, a pair of disk-like guide members (65) and (66) are brought into contact with the axial both end faces of a conductor (61) wound in a coil shape by using a separable tool. Parts of the conductor (61) are engaged with engagement parts (65c) and (66c) formed around the pair of guide members (65) and (66) and the pair of guide members are energized in directions for moving them close to each other, and then the tool is separated from the center of the conductor (61). By this, the shape of the bobbin-less coil (46) in which the inner peripheral surface of the conductor (61) wound in the coil shape is exposed can be retained. Also, since the pair of disk-like guide members (65) and (66) are energized in the directions for moving them close to each other by utilizing the parts of the conductor (61), the need of a special material for energization can be eliminated.
