| titleOfInvention | Closed magnetic circuit type tubular coil and method of manufacturing the same |
| abstract | (57) [Summary] [PROBLEMS] In an open magnetic circuit coil, magnetic noise is generated from the coil, which adversely affects peripheral devices and the like. SOLUTION: A core part 1 having a coil part 3a formed by winding a predetermined number of turns of a coil 3 on a coil core 2 made of a magnetic material such as permalloy and having flanges 2a and 2b at both ends, and the core part 1 is formed. A closed magnetic circuit type comprising a bottomed cylindrical bobbin 4 having narrowed portions 4a and 4b fitted with the flanges 2a and 2b, and a core 1 formed into a closed magnetic circuit by press-fitting and fixing the core 1 to the cylindrical bobbin 4. The cylindrical coil 5 is constituted. Between the outer diameter D1 of the first flange 2a on the bottom side of the cylindrical bobbin 4 and the outer diameter D2 of the second flange 2b on the opening side, D2> D1 so that the press-fitting can be smoothly performed. I do. It is possible to provide an inexpensive closed magnetic circuit type tubular coil which is hardly affected by magnetic noise when installed in a device. |
