<p>PROBLEM TO BE SOLVED: To readily obtain a divided winding structure of horizontal type and in which a primary winding and a secondary winding are alternately wound three times or more. SOLUTION: A bobbin 2 of a transformer 1 is provided with three winding fitting grooves, and after each of grooves is wound by a secondary winding S1, a primary winding P, and a secondary winding S2 in the order, the leading end and terminal of the respective winding are respectively wound around a pair of pins provided on the partitioning walls of both sides, and pins t1 and t3, in which the leading ends of the secondary windings S1 and S2 are wound, are connected with each other by the circuit pattern PC13 of a circuit board, while other pins t2 and t4 in which the terminals of the secondary windings are wound are connected to each other by a jumper wire 10.</p> |
