Abstract

The invention relates to an inductive device comprising terminals (9) mounted to the inductive device from outside the ring core (7). A fixed area (12) of a terminal (9) is bent along the outer wall (14), the top surface (15) of the groove (19) and the inner wall (13) of the ring core (7). A mounting area (11) of a terminal (9) extends along the lower edge (3) from near the outer circumference of the ring core (7) towards the interior of the drum core (4). When the drum core (4) or the ring core (7) is subjected to vibration, this structure prevents the drum core (4) and the ring core (7) from being detached from the plate on which they are mounted, and the terminal (9) The adjacent portion of the fixed area (12) is left on the board. Therefore, this structure improves the vibration resistance of the inductive device.

Description

technical field [0001] The present invention relates to an inductive device used in various electronic equipment. technical background [0002] Hereinafter, a conventional inductance device will be described with reference to the accompanying drawings. A conventional inductor device is disclosed in Japanese Patent Application Unexamined Application No. H10-294221. Figure 10 is a perspective bottom view of this conventional inductive device, Figure 11 yes Figure 10 An exploded perspective view of the inductive device shown in . [0003] exist Figure 10 and Figure 11 , this conventional inductive device consists of the following components: [0004] drum core 24; [0005] Winding 25; [0006] ring core 26; and [0007] Terminal 27. [0008] The drum core 24 has an upper edge 22 on a first end of the roller shaft 21 and a lower edge 23 on a second end of the roller shaft 21 . The diameters of the two edges are approximately the same. The winding 25 is wound on the...
