Abstract:
The present invention relates to a locking spring member and a rotary isolating switch. The locking spring member comprises: an annular component having a through hole and a notch extending radially along the through hole, with the notch being in communication with the through hole; and a mandrel connector, comprising a fixing portion and a mounting portion connected to each other. The mandrel connector is connected to the annular component via the fixing portion, and the mounting portion is disposed in the through hole. The mounting portion comprises one disk body and two or more mandrel matching protrusions, and the disk body is provided with a positioning hole. The axis of the positioning hole coincides with or is parallel to the axis of the through hole, and the two or more mandrel matching protrusions are disposed around the positioning hole and are spaced apart from each other, and also extend from the edge of the disk body that is adjacent to the positioning hole in the axial direction of the positioning hole. The locking spring member of the present invention has a simple structure and includes a small number of structural members, thereby improving the overall individual strength thereof, being able to improve the capacity to bear load impacts, and being less prone to damage.
