LOW VOLTAGE BOBBIN OF FLY BACK TRANSFORMER

摘要

PURPOSE: A low voltage bobbin of a fly back transformer is provided to easily manufacture various ferrite cores having a circular shape or an ellipse shape by only using one low voltage bobbin. CONSTITUTION: A low voltage coil(110) winds around an outer surface of a bobbin main body(130) of the FBT low voltage bobbin. One end of a ferrite core(140) is inserted into the bobbin main body(130). An ellipse shape of core engaging groove(150) is formed through the bobbin main body(130). Locking protrusions(160) protrude from an outer surface of the bobbin main body(130). The locking protrusions(160) support the low voltage coil(110) wound around the outer surface of the bobbin main body(130). The ferrite core(140) has an ellipse shape of section or a circular shape of section.
