Abstract

PURPOSE:To simulate sectional configuration of a coil bobbin to practical installation configuration of a coil to uniform the surface pressure applied to a bobbin and prevent looseness between core and bobbin, by a method wherein thickness of the sectional configuration of a coil bobbin is thin at corner edge portion and gradually increases towards the center portion. CONSTITUTION:When coil bobbins 21 and 22 divided into two are installed to a core 1, and a coil 5 is wound thereon, the thickness of the section in perpendicular direction to the bobbin axial direction is thin at a corner edge portion 24 and the thickest at the center portion, and gradually decreased from the center portion towards the corner edge portion. In this constitution, sectional configuration of a bobbin 20 is simulated approximately to practical installation state of the coil 5 thereby decrease of allowable value of temperature of thermal deformation is prevented, and looseness does not occur even used under overheating.
