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.

L'invention concerne un noyau de fer monté dans un transformateur, un redresseur, un stabilisateur, une lampe et analogues. Lorsque le noyau de fer est formé, un noyau de fer en forme de E et une paire de noyaux de fer en forme de .subset., disposés sur les deux côtés du noyau de fer en forme de E, sont simultanément estampés à partir d'une feuille d'acier au silicium. Un nombre prédéterminé de noyaux de fer en forme de E et de paires de noyaux de fer en forme de .subset. sont assemblés et stratifiés de sorte à former un noyau de fer stratifié. Ce noyau de fer comprend le noyau de fer en forme de E comprenant des pieds latéraux formés symétriquement sur ses deux côtés et un pied central formé entre les pieds latéraux et couplé à une bobine autour de laquelle est enroulé un serpentin, et la paire de noyaux de fer en forme de .subset., chaque noyau comprenant un pied long formé correspondant au pied latéral du noyau de fer en forme de E et un pied court formé correspondant au pied central du noyau de fer en forme de E.
