Abstract

The invention provides an inductor and transformer combined mechanism, and relates to the technical field of power distribution system equipment manufacturing, the inductor and transformer combined mechanism comprises an inductor assembly and a transformation assembly, the inductor assembly comprises a first iron core and a plurality of groups of copper sheet windings wound along the periphery of the first iron core at intervals, and the transformation assembly comprises a second iron core and a plurality of groups of copper sheet rings wound along the periphery of the second iron core at intervals. The copper sheet winding is inserted into the first conductive support in a radial mode, the copper sheet ring is inserted into the second conductive support in an axial mode, and the first conductive support is connected with the second conductive support. In order to improve the stability of the copper sheet structure under electrical impact, the second conductive support is provided with a fixing assembly, the fixing assembly comprises an adjusting part and an extrusion part, and the extrusion part can be switched to a first state or a second state under the action of the adjusting part. In the first state, the extrusion piece is contained in the support. And in the second state, the extrusion piece limits the radial movement of the copper sheet winding and the axial movement of the copper sheet ring, and the reliability and deformation resistance of electrical connection can be enhanced.
