JPS5696821A - Leakage transformer - Google Patents

Abstract

PURPOSE:To readily correct the irregularity in the characteristics of the leakage transformer during production by providing a holder for restricting the position of an iron core at the magnetic leakage part at one bobbin when a pair of bobbins with flange wound with windings are engaged with the outer periphery of the iron core as the leakage transformer. CONSTITUTION:A pair of coil bobbins B1, B2 of synthetic resin are engaged with the central leg of the iron core F as the leakage transformer. In this structure a primary coil winding part D and a filament coil winding part E are provided on the botton B1, a primary coil P is wound on the part D, and a filament coil f1 is wound on the part E. Similarly, a secondary coil winding part L and a filament coil winding part M are similarly provided at the bobbin B2, and when secondary coil winding S and filament coil winding (f) are wound thereon, a magnetic branch space N for restricting the position of the magnetic leakage part is provided between the parts M and L. Thus, the length of the space N is adjusted, and the voltage generated at the filament coil is equalized.
