Claims

[Claims for Utility Model Registration] (1) Two coils are wound around an annular upper and lower split insulating case that houses a toroidal magnetic core inside, and are inserted into a position that bisects the central through hole of the case. In the toroidal inductor element, the toroidal inductor element includes a base member that is connected to the insulating case by an upper partition plate, the base member is formed into a substantially rectangular shape, and two side surfaces located on the sides of the upper partition plate are formed. In addition, outer notches for passing the coil terminals are formed at four symmetrical locations sandwiching the partition plate vertically and horizontally, and in a symmetrical area at the center sandwiching the top partition plate, Elongated openings for passing through each pair of coil terminals are provided parallel to the surface of the partition plate, and one columnar terminal is planted in each of approximately four corners of the lower surface of the base member, and at appropriate locations on the lower surface. A toroidal inductor element characterized in that it is configured to form a plurality of protrusions that can come into contact with a circuit board. (2) The above-mentioned upper and lower two-divided insulating case has several coil partition walls on the outer surface of each case part with recesses in opposing parts of each case part.A utility model registration request. The toroidal inductor element according to the range 1 above. (3) The toroidal inductor element according to claim 1 or 2, wherein the upper and lower two-divided insulating case and the base member are made of the same insulating synthetic resin. .
