Title:
WINDING TYPE COIL
Document Type and Number:
WIPO Patent Application WO/2010/073661
Kind Code:
A1
Abstract:
Provided is winding type coil that prevents an outer flange section of the winding type coil and a mounting substrate from coming into contact to prevent the outer flange section from being damaged and the wrapped conductive wire from shifting or unwinding. A concave groove (12a) is formed in the outer surface of a flange (8a), and an inner flange section (13a) and an outer flange section (14a) are formed on both sides of the concave groove (12a). Then, the distance (L1) from the bottom surface (15a) of the concave groove (12a) at least to the outer surface of the outer flange section (14a) which faces a mounting substrate (10) is smaller than the distance (L2) from the bottom surface (15a) of the concave groove (12a) to the inner flange section (13a). In addition, a second winding section (22a) is formed in the concave groove (12a) such that the distance (L3) from the bottom surface (15a) of the concave groove (12a) to the outer surface of the second winding section (22a) which faces the mounting substrate (10) may be larger than the distance (L1), but the difference between the distance (L3) and the distance (L1) is smaller than the diameter (D) of the conductive wire (20).
