Title:
TRANSFORMER
Document Type and Number:
Japanese Patent JP2015065413
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transformer that facilitates adjustment of leakage characteristics, has superior insulation quality, can be made compact while adapted to higher frequencies although a larger current flows, and also has superior heat dissipation properties.SOLUTION: A transformer 10 has a bobbin 20. A cylinder part 28 of the bobbin 20 includes a first winding part 35 wound with a first wire 37, and a second winding part 36 wound with a second wire 38 at an axially different position from the first winding part 35. An insulation partition wall flange 30 is formed at an outer periphery of the cylinder part 28 positioned between the first winding part 35 and second winding part 36, and the first winding part 35 has a winding partition wall flange 33 for separating sections S1, S2 individually formed; and the winding partition wall flange 33 has at least one connection groove 33a for mutually connecting the respective adjacent sections S1, S2 to each other formed, and the first wire 37 is α-wound around the first winding part 35.
