Abstract
An inductor (100) includes a pair of magnetic members (cores (10, 20)), a main body having coils (71, 72), and a sheet-formed fixation member (60), wherein the fixation member (60) is bound across the cores (10, 20) and the main body, to thereby fix the cores (10, 20) which configure a closed magnetic path, and to thereby fix at least one of the cores (10, 20) to the main body.
Claims12
An inductor comprising:
- a main body, the main body having a coil that is configured by a wound wire so that the coil has an opening at an inside thereof;
- first and second magnetic members, the first magnetic member having a first end, the second magnetic member having a second end, the first magnetic member being magnetically secured to the second magnetic member at the first and second ends, the first and second magnetic members being located at both sides of the coil so as to laterally surround part of the coil by being magnetically secured at the first and second ends, the first magnetic member having a rod-shaped projection, the rod-shaped projection being inserted into the opening of the coil so as to form a closed magnetic path with the second magnetic member when the first and second magnetic members laterally surround the part of the coil;
- and
- an adhesive tape on which an adhesion is provided, the adhesive tape extending in a longitudinal direction so that the adhesive tape has first and second sides opposite to each other along the longitudinal direction,
- wherein the adhesive tape is continuously provided on an area including the first and second ends and part of the main body so that the adhesive tape fixes the first and second magnetic members to each other and fixes one of the first and second magnetic members to the part of the main body when the first side of the adhesive tape is located on the part of the main body,
- wherein the main body has a base that is located between a board on which the inductor is mountable and the first and second magnetic members, the main body is configured with a second member containing a cover which covers the coil and a first member containing a plurality of terminals which are connectable to the board, and parts of the first and second members configure the base,
- part of the base on which the adhesive tape is fixed is configured by a first plane of the first member and a second plane of the second member, and
- the adhesive tape is provided across the first plane and the second plane so as to fix the first and second members.

A method of manufacturing an inductor, the method comprising:
- providing the inductor with:
- a main body, the main body having a coil that is configured by a wound wire so that the coil has an opening at an inside thereof;
- first and second magnetic members, the first magnetic member having a first end, the second magnetic member having a second end, the first magnetic member having a rod-shaped projection;
- and
- an adhesive tape on which an adhesion is provided, the adhesive tape extending in a longitudinal direction so that the adhesive tape has first and second sides opposite to each other along the longitudinal direction;
- configuring a closed magnetic path by:
- placing the first and second magnetic members at both sides of the coil so as to laterally surround part of the coil by being magnetically secured at the first and second ends;
- and
- inserting the rod-shaped projection into the opening of the coil so as to form the closed magnetic path with the second magnetic member when the first and second magnetic members laterally surround the part of the coil;
- and
- continuously providing the adhesive tape on an area including the first and second ends and part of the main body so that the adhesive tape fixes the first and second magnetic members to each other and fixes one of the first and second magnetic members to the part of the main body when the first side of the adhesive tape is located on the part of the main body,
- wherein the main body has a base that is located between a board on which the inductor is mountable and the first and second magnetic members, the main body is configured with a second member containing a cover which covers the coil and a first member containing a plurality of terminals which are connectable to the board, and parts of the first and second members configure the base,
- part of the base on which the adhesive tape is fixed is configured by a first Diane of the first member and a second plane of the second member, and
- the adhesive tape is provided across the first plane and the second plane so as to fix the first and second members.
