Abstract
A magnetic assembly includes a bobbin and first and second cores. Each core has a main body. At least one of the cores has first and second outer legs and a center leg extending from the main body. The bobbin includes a first channel on a first end flange and a second channel on a second end flange. Each channel includes a plurality of crushable ribs that extend into the channel. The first and second cores are inserted into the respective first and second channels to engage and crush the crushable ribs. The crushed ribs frictionally engage the main bodies of the two cores to retain the two cores in a fixed relationship with the bobbin without requiring tape or glue. In one embodiment, both cores are E-cores. In another embodiment, one core is an extended E-core and the other core is an I-core.
