  • Patent number: 6747538
    Abstract: An inductance device includes terminals (9) which are mounted to the inductance device from outside of a ring core (7). A fit-section (12) of one of each terminal (9) is bent along an outer wall (14), an upper face (15) of a groove (19), and an inner wall (13) of the ring core (7). A mount-section (11) of one of each terminal (9) extends from vicinity of an outer perimeter of the ring core (7) toward inside of a drum core (4) along a lower brim (3). When a shock is applied to the drum core (4) or the ring core (7), this structure prevents the drum core (4) and the ring core (7) from falling away from a board, where they have been mounted, leaving vicinity of the fit-section (12) of the terminal (9) on the board. This structure thus improves shock-proofness of the inductance device.

  • Patent number: 5913551
    Abstract: In an inductor including a magnetic core on a top surface of a terminal table, a plurality of L-shaped conductors are inserted into the terminal table so that two ends of each of the L-shaped conductors are projecting from a side surface of the terminal table. The plurality of L-shaped conductors each have at least one stepped portion. One of the two ends which is on a higher level than the stepped portion acts as a winding terminal around which the wire is wound, and the other end which is on a lower level than the stepped portion acts as a mounting terminal used for mounting of the inductor. The winding terminal is projecting from a higher level of the side surface of the terminal table than the mounting terminal.
