WINDING COMPONENT

摘要

A winding component includes a core that surrounds an outer circumference of a coil and end surfaces of flanges to form a closed magnetic circuit, in which notches through which end portions of the coil are drawn outward are so formed in the flanges that each of the notches extends radially inward from an outer circumferential edge of the corresponding flange, a wall that surrounds each of the notches such that the wall stands axially outward on the flange, a thick portion in a winding part in correspondence with the notches and thicker than other portions of the winding part, and a lid formed of a sidewall between an outer circumferential surface of the wall and the core and covers the outer circumferential surface of the wall and a top plate at an axially outer end of the sidewall and covers an opening in the wall.

1. A winding component comprising:
a bobbin having flanges formed at axially opposite ends of a tubular winding part; a coil wound around the winding part of the bobbin; and a core that surrounds an outer circumference of the coil and end surfaces of the flanges to form a closed magnetic circuit, wherein notches through which end portions of the coil are drawn outward are so formed in the flanges that each of the notches extends radially inward from an outer circumferential edge of the corresponding flange, a wall that surrounds each of the notches is so provided that the wall stands axially outward on the flange, a thick portion is formed in the winding part in correspondence with the notches and is made thicker than other portions of the winding part, and a lid formed of a sidewall that is disposed between an outer circumferential surface of the wall and the core and covers the outer circumferential surface of the wall and a top plate that is formed at an axially outer end of the sidewall and covers an opening in the wall is provided.
