Abstract
A magnetic assembly includes a bobbin having at least first and second end flanges. The bobbin includes a channel wall displaced from the first end flange to from a channel therebetween. The channel receives and frictionally engages an I-core to retain the I-core in the channel. The bobbin includes a passageway that receives a middle leg of an E-core. The passageway includes a plurality of longitudinal ribs that extend from the first end flange toward the second end flange. The ribs are tapered with respect to the inner wall of the passageway. The middle leg of the E-core crushes the ribs. The frictional engagement of the crushed ribs with the middle leg retains the middle leg in the passageway. No taping, gluing or other additional step is required to assemble the bobbin and the two cores.
