Title:
TRANSFORMER
Document Type and Number:
Japanese Patent JP3816687
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transformer with high reliability capable of preventing disconnection of thinned coil ends by an external force generated upon mounting.
SOLUTION: A coil bobbin 11 is provided with a plurality of coil winding 151-156 and contains a core insertion hole 16 penetrating in the axial direction. A coil 22 has a cross-sectional area smaller than that of a coil 21. The other end of a terminal 31 is led out from an end surface other than a mounting surface 121 and is connected to an end 221 of the coil 22, whose line diameter is thinner. A first core member 4 is inserted into the core inserting hole 16, and both ends are led out of the core inserting hole 16. A second core member 5, whose both ends are connected to both ends of the first core member 4, constitutes a magnetic path, together with the first core member 4.
