Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To eliminate vibration noises generated by repetition of attraction and repulsion due to an electromagnetic force, which is generated between coil windings, when an AC current is made to flow in a toroidal coil for a large current, where a flat wire is wound upright around a core formed by winding a magnetic thin plate, and to realize a small-sized line filter by forming a small-sized toroidal coil. SOLUTION: At least on lower parts of the ring core of a toroidal coil and a wound flat wire which are mounted on a board are bonded and fixed to the board, so that the vibrations between coil windings can be prevented. Except for the intermediate part of the coil, the ring core and the flat type wire are bonded mutually and fixed in an upper part and a lower part of the coil, so that two parts of the coil are fixed at each turn. Thereby the vibrations can be restrained, even in the case of a densely wound toroidal coil for a large current, the intermediate part of the coil is exposed to air, heat is easily dispersed, and temperature rise of the toroidal coil can be restrained. By winding a multilayered flat type wire in a rectangle, a small-sized toroidal coil is formed. By inserting a zigzag bent sheet between windings, shortcircuiting can be readily prevented.
