Abstract
A ferrite component is provided for forming a ferrite bobbin about which an electric conductor is wound. The component is formed with an enlarged flange portion from which extends a shaft portion that defines a free end. The free end of the shaft portion has at least one outwardly extending projection and at least one recessed hollow which are similarly shaped and dimensioned. Two of the ferrite components are mated together to form the bobbin with the projection of one component extending into the hollow of the other component and vice versa.
Claims5
A ferrite bobbin formed from two identical components, each said component comprising:
- a ferrite, disc-shaped flange portion having spaced-apart first and second axial ends and a peripheral surface extending therebetween, said flange portion having slots formed at diametrically opposed locations to facilitate the winding of wire and to provide a passage for support pins;
- and
- a ferrite shaft portion extending from and being unitarily connected to said first axial end of said flange portion, said shaft portion defining a free end spaced from and generally facing away from said first axial end of said flange portion, wherein said free end is formed to define at least one planar portion, at least one projection extending beyond said planar portion and away from said flange portion, and at least one hollow recessed below said planar portion in a direction towards said flange portion, wherein said projection and said hollow are formed with substantially identical cross-sectional shapes, wherein said flange portion defines a first cross-sectional dimension, said shaft portion defines a second cross-sectional dimension at said free end, said second cross-sectional dimension being less than said first cross-sectional dimension, whereby said free end of said component is mated with a second like component in an intimate engagement to form the ferrite bobbin and to ensure proper axial alignment between said components and said slots.
