Embodiment Construction
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] An iron-silicon-aluminum powder integrated pressing inductor is characterized in that: a red copper strip 1 is used as a coil, the middle part of the red copper strip 1 is wrapped in the iron-silicon-aluminum block 2, and the exposed parts at both ends are welding feet, the surface of which is plated There are nickel and tin; the cross section of the iron-silicon-aluminum block 2 is inverted "convex" shape, so that the shoulder position at the bottom of the iron-silicon aluminum block 2 forms two avoidance spaces 3; the red copper strip 1 The two welding feet are respectively bent down along the side of the iron-silicon-aluminum block 2, and are folded inside the bottom of the iron-silicon aluminum block 2, and the bent parts are correspondingly close to the positions of the above two avoidance spaces 3; The upper surface of the iron-silicon-alumin...
