摘要： Provided is a reactor that includes: a coil; a magnetic core with an inner core portion arranged inside the coil; and an inwardly interposed member insulating the inner core portion from the coil. The inwardly interposed member has a thin portion defined by a recessed inner-circumferential surface, and a thick portion that is thicker than the thin portion. The inner core portion has a core-side projection portion facing the inwardly interposed member that has a shape conforming to the inner-circumferential surface shape of the thin portion. The thin portion has a thickness of 0.2 mm to 1.0 mm inclusive, and the thick portion has a thickness of 1.1 mm to 2.5 mm inclusive. A clearance is provided at least at a portion between the inner core portion and the inwardly interposed member, and the inwardly interposed member and the wound portion are in contact with each other.

摘要： A reactor includes a coil, a magnetic core having an inner core portion inside a winding portion, and an inner interposed member insulating the winding portion from the inner core portion. The inner interposed member includes a thin portion with a small thickness formed by a recess, and a thick portion with a thickness larger than that of the thin portion. The inner core portion includes a core-side projecting portion with a shape conforming to a shape of the inner peripheral face of the thin portion. The thickness of the thin portion is 0.2 mm or more and 1.0 mm or less, and the thickness of the thick portion is 1.1 mm or more and 2.5 mm or less. Clearances are in part of a portion between the inner core portion and the inner interposed member and of a portion between the inner interposed member and the winding portion.

摘要： Provided is a reactor that can be manufactured without holding an assembly when the assembly is fixed to a mounting plate via a bonding layer. The reactor includes a coil, a magnetic core, an interposed insulating member, a metal mounting plate, and a bonding layer. The interposed insulating member is provided with an inwardly interposed portion, a first interposed end face portion, and a second interposed end face portion. The interposed insulating member is obtained by combining a plurality of divided pieces that includes a divided piece having the first interposed end face portion, and a divided piece having the second interposed end face portion. The divided pieces are respectively provided with engaging portions that engage with each other, and the first interposed end face portion and the second interposed end face portion are each provided with a leg piece that separates the coil from the mounting plate.

摘要： A reactor includes a coil; a magnetic core with an inner core portion arranged inside the coil; and an inwardly interposed member insulating the coil from the inner core portion. The inwardly interposed member has a thin portion defined by a recess of an inner-circumferential surface, and a thick portion that is thicker than the thin portion. The inner core portion has, on an outer circumferential surface facing the inwardly interposed member, a core-side projection portion has a shape conforming to the inner-circumferential surface shape of the thin portion. The thin portion has a thickness of 0.2 mm to 1.0 mm inclusive, and the thick portion has a thickness of 1.1 mm to 2.5 mm inclusive. The inner core portion and the inwardly interposed member are in intimate contact with each other, and the inwardly interposed member and the wound portion are in intimate contact with each other.
