1. An inductor framework, comprising a main winding part and at least two conductive welding components, wherein the main winding part is provided with a limited groove; wherein:
the main winding part is configured to fix a winding and has a connection surface facing downward, the conductive welding components are under the connection surface and at least partly cover the connection surface, and the conductive welding components are in fixed connection with the main winding part and the at least two conductive welding components are insulated from each other; and
a side surface of the conductive welding components away from the connection surface is a welding bonding surface, and the conductive welding components have a wire accommodation region, wherein the wire accommodation comprises a wire groove, and the wire accommodation region is configured that a wire of the winding do not extend beyond the welding bonding surface in a case where the wire of the winding is accommodated in the wire accommodation region, wherein an end of the limited groove extends into the wire groove, and the conductive welding components cover an entirety of the connection surface, and the conductive welding components are further provided with a wire passage channel interconnecting the wire groove and the limit groove.
