Abstract

PROBLEM TO BE SOLVED: To reduce the size of a fluorescent lamp stabilizer, etc., incorporating a transformer and at the same time, to reduce the utilization amount of a filler in the stabilizer, etc. by providing terminal blocks only in the flange section of either one of the primary- and secondary-side bobbins of the transformer. SOLUTION: A coil 5a is composed of a primary coil 10a and a secondary coil 15 which are formed by respectively winding conductors 8 around a primary bobbin and a secondary bobbin by prescribed numbers of times, and the primary bobbin having flange sections 13 and 13 on both sides and the secondary bobbin having flange sections 17 and 17 on both sides are connected in series. In addition, terminal blocks 9 and 9 are integrally provided on the outer flange section 13a of the primary bobbin in a state, where the blocks 9 and 9 are faced opposite to each other in the vertical direction. However, no terminal block is provided on the outer flange section of the secondary bobbin. Moreover, a plurality of terminals 19 are press-contacted with each terminal block 9. Therefore, the utilization amount of a resin filling up a fluorescent lamp stabilizer incorporating a transformer can be reduced, because the length of the stabilizer in the longitudinal direction can be reduced.
