<p>PURPOSE:To lessen copper loss and raise efficiency and lower the height and increase dielectric breakdown strength. CONSTITUTION:This is equipped with a bobbin 10, which has a spool 12 projecting upward, with terminals planted on its two side faces, a primary winding 30, which is wound on the spool 12, a secondary winding 50, which is electromagnetically coupled with the primary winding 30, being wound in a line into multilayer from inside to outside and arranged below the bobbin 10, a first core 60 of E-shaped cross section, and a plateshaped second core 70, and an insulating sheet 40, which has a cut 45. And, the lead wire 51a on the side of start of secondary winding 50 is led out below a sheet 40 from the cut 45, and also the lead wire 31 of the primary winding 30 and the lead wire 51 of the secondary winding 50 are connected to the terminals on the different sides of the bobbin 10, respectively.</p> |
