Abstract
PURPOSE:To facilitate miniaturization and improvement of anti-shock property by providing a magnetic core in the coil of booster and composing a magnetic circuit of a magnetic core and a yoke made by bending soft magnetic material thereby making higher saturation magnetic flux density. CONSTITUTION:A coil block of a booster coil comprises a coil 10, a magnetic core 11 and a lead substrate 12. The end of the coil 14a is soldered to the conductor 13 of the substrate 12 and the other end 14b is directly soldered to the conductor 13 of the substrate 12 and the other end 14b is directly soldered to the magnetic core 11. The coil 10 is wound on the substrate 12 bonded to a recess formed at a part of the magnetic core 11. A circuit pattern is formed on an insulative substrate of an electronic circuit substrate 16. A yoke 18 is formed at a bent parts 17, 18 of soft magnetic material. The conductor part 13 of the substrate 12 and the circuit pattern are placed contracting with each other and, on the top of them, the yoke 18 is inserted into a hole 15 of the circuit substrate and the coil block is fixed by the bent parts 17, 18 to miniaturize the booster coil and to improve anti-shock property.
