Abstract
A magnetic core assembly with coils therein has a substantially spherical or ellipsoidal main body defining a hollow space therein. A column is disposed in the main body so as to be aligned with a center line of the main body. The main body is defined by a pair of separated halves. The main body has a slot extending outward form the hollow space, and the slot aligns with a separating plane of the halves. The core assembly has a bobbin that is formed with a barrel wound by the coils, and the barrel has a through hole receiving the column of the core assembly. The bobbin has a retainer plate arranged with terminals for the coils. The retainer plate extends from the main body via the slot. A mounting board for the core assembly is formed with an opening to receive the spherical or ellipsoidal main core body such that the mounting board supports the core body on a periphery of the opening.
