Abstract

An iron core built in a transformer, a rectifier, a stabilizer, a lamp, and others is disclosed. When the iron core is formed, an E-shaped iron core and a pair of c -shaped iron cores, which are arranged on both sides of the E-shaped iron core, are simultaneously stamped from a sheet of silicon steel. A predetermined number of E-shaped iron cores and pairs of c -shaped iron cores are assembled and laminated to form a laminated iron core. The iron core includes the E-shaped iron core having side legs symmetrically formed on both sides thereof and a center leg formed between the side legs and coupled to a bobbin around which a coil is wound, and the pair of C-shaped iron cores each having a long leg formed corresponding to the side leg of the E-shaped iron core and a short leg formed corresponding to the center leg of the E-shaped iron core.
