CORE FOR A WIRE-WOUND ELECTRONIC COMPONENT, A WIRE-WOUND ELECTRONIC COMPONENT AND A METHOD FOR MANUFACTURING A CORE FOR A WIRE-WOUND ELECTRONIC COMPONENT

摘要

A wire-wound electronic component, a core for a wire-wound electronic component and a method for manufacturing a core for a wire-wound electronic component are provided. A winding core portion of a core of a wire-wound electronic component includes flanges at respective ends of the winding core portion, and project in directions perpendicular to an axial direction of the winding core portion. Concaves are positioned at corners formed of adjoining surfaces of the flanges that adjoin to the winding core portion and end surfaces of the flanges that are located at ends in a first perpendicular direction, which is one of the projecting directions of the flange. Connecting surfaces, which connect contact portions where the flanges contact with the winding core portion to the end surfaces, are at least part of inner peripheries of the concaves. All normal vectors of the connecting surfaces have components in the first perpendicular direction.

主权项

1. A core for a wire-wound electronic component, the core comprising:
a winding core portion around which a winding wire is to be wound; flanges provided at respective ends of the winding core portion, the flanges projecting from the winding core portion in directions perpendicular to an axial direction of the winding core portion; and concaves at respective corners, each corner formed of an adjoining surface of one of the flanges that adjoins to the winding core portion and an end surface of the flange that is located at an end in a first perpendicular direction, which is one of the projecting directions of the flanges; wherein at least part of inner periphery of each of the concaves includes a connecting surface that connects a contact portion where one of the flanges contact with the winding core portion to one of the end surfaces, and all normal vectors of the connecting surfaces have components in the first perpendicular direction.
