Abstract

An inductive electric component, in particular an electric transformer, includes a coil body having coil body flanges defining a winding space, and contact pin strips integrally formed onto the coil body flanges, the contact pin strips having extensions and having free ends with undercuts formed therein being limited outwardly by the extensions. A two-part magnet core has halves with center bosses to be pushed together on the coil body with the center bosses engaging the coil body and resting on the coil body flanges and on the contact pin strips. A spring cap is to be slipped onto the magnet core disposed on the coil body for retaining the magnet core halves on the coil body. The cap has a yoke with a middle region. The yoke is concave at least in the middle region, and the yoke has legs on two opposite sides and spring hoops on two other opposite sides. The legs each have detent protrusions locking into the undercuts with the spring cap slipped on. With the spring cap slipped on, the concave region engages an outer surface of the magnet core facing away from the contact pin strips, the legs rest on two opposite outer surfaces of the magnet core being perpendicular to the contact …
