Abstract
A switching contact, of a vacuum interrupter including support bodies, includes an additional support body which has the shape of a truncated cone or of a hollow truncated cone or of a partially hollow truncated cone. The additional support body is offset from a first location or region on the bottom of the contact carrier, located in the notional extension of the contact rod and inside the contact carrier, to a second location or region, located on the side of the contact plate facing the contact carrier and on the outer edge of the contact plate in relation to the first region.
Claims19
A switching contact for a vacuum switch, comprising:
- a contact bar;
- a contact carrier, electrically conductively connected to the contact bar;
- a contact disk, electrically conductively connected to the contact carrier;
- a supporting body, extending from the contact disk in a direction of at least one of the contact bar and the contact carrier such that sinking of the contact disk is at least one of prevented and reduced, the supporting body being held in a position, between the contact disk and the contact carrier or an additional supporting body, at least one of
- by shaping of at least one of the contact disk, the contact carrier and the additional supporting body and
- by soldering;
- and
- the additional supporting body, having a shape of a truncated cone or of a hollow truncated cone or of a partially hollow truncated cone, the additional supporting body extending from a first location, on a base of the contact carrier located in an imaginary extension of the contact bar and within the contact carrier, to a second location, located on a side of the contact disk facing the contact carrier and offset in relation to the first location to an outer edge of the contact disk, the additional supporting body being connected to the contact disk and being connected to the contact carrier, wherein the additional supporting body is of two-part design including a first additional supporting body and a second additional supporting body, and the truncated cone or hollow truncated cone or partially hollow truncated cone is formed by
- the first additional supporting body soldered to the contact carrier, and
- the second additional supporting body soldered to the contact disk, wherein the first additional supporting body and the second additional supporting body are soldered to one another.
