CN-224233972-U - Controller and electric driving system

Abstract

The embodiment of the application relates to a controller and an electric driving system, wherein the controller comprises a plurality of conductive posts, a PCB, a fastener and a supporting piece which are arranged at intervals, the conductive posts are provided with a welding part and a connecting part, the welding part is welded to the PCB, the connecting part is used for electrically connecting external equipment, and the PCB is locked to the supporting piece through the fastener. Because the welding part of the conductive column is welded to the PCB, the conductive column is not required to be additionally provided with a mounting part for locking with the PCB, the conductive column is small in size, and the layout flexibility of the conductive column on the PCB is high. In addition, because the conductive post is welded on the PCB, and the PCB is locked on the supporting piece through the fastener, the risk that the conductive post rotates due to the torque when the conductive post is locked with external equipment is greatly reduced.
