Patent ID: 11215233

Abstract:
A rotating spindle capable of conductively contacting via bearings contains: a power supply module, a body, a first conductive assembly, and a second conductive assembly. The power supply module includes a first circular shell, an insulation element, a second circular shell, a first bearing, and a second bearing. The body is accommodated in the first circular shell and includes two elongated orifices, two guide orifices, and two electrode orifices. The first conductive assembly includes a first internal conductive wire, a first external conductive wire, and a first electrode. The first internal conductive wire is connected with the first electrode and extends out of the one guide orifice. The second conductive assembly includes a second internal conductive wire, a second external conductive wire, and a second electrode. The second internal conductive wire is connected with the first electrode and extends out of the other guide orifice.
