Abstract
Official abstract text for this publication.
A switching contact drive device contains a transmission with an energy store. The energy store is enclosed in a housing. The housing guides a relative movement, particularly a deformation of the energy store. The switching contract drive device is provided for driving an electrical switching device such as a circuit breaker.
First claim
Opening claim text (preview).
1 - 7 . (canceled) 8 . A switching contact drive device, comprising: a transmission with an energy store for an electrical switching device; and a store housing enclosing said energy store. 9 . The switching contact drive device according to claim 8 , wherein said store housing directs a relative movement of said energy store. 10 . The switching contact drive device according to claim 8 , further comprising a joining point incorporated in said store housing transversely to a relative movement of said energy store. 11 . The switching contact drive device according to claim 10 , wherein said store housing has a gate passage for guiding a movement of said energy store and said gate passage is disposed transversely to said joining point. 12 . The switching contact drive device according to claim 8 , wherein said transmission has a transmission housing and said store housing is mounted on a mating surface of said transmission housing. 13 . The switching contact drive device according to claim 11 , wherein said store housing has form-fitting elements, said gate passage is centered in a mating surface by means of said form-fitting elements. 14 . The switching contact drive device according to claim 8 , wherein said store housing directs a deformation of said energy store. 15 . An electrical switching device, comprising: switching contact points, including a first switching contact point and a second switching contact point which are moveable relative to one another; and a switching contact drive device for generating a relative movement between said switching contact points, said switching contact drive device containing a transmission with an energy store and a store housing enclosing said energy store.
