AI Technical Summary
The existing transformer core is prone to displacement and loosening during installation, and the limiting effect is not good, resulting in poor stability.
The iron core body consists of a first E-type core, a second E-type core, a long limiting arm, a short limiting arm, and a long screw. The silicon steel sheet is limited by the matching of the limiting slot and the screw hole. The positioning hole and the positioning convex and concave structure improve the assembly accuracy and stability.
This effectively prevents the silicon steel sheets from loosening, improves the overall stability and assembly precision of the transformer core, and enhances the limiting effect.
