Abstract

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

The invention claimed is:

1. 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;
a joining point incorporated in said store housing transversely to a relative movement of said energy store, said store housing having a gate passage for guiding a movement of said energy store and said gate passage being disposed transversely to said joining point, said store housing having form-fitting elements, said gate passage being centered in a mating surface by means of said form-fitting elements;
a second store housing having a second energy store and diametrically opposed second gate passages being oriented in a linear profile, said second gate passages each being swept by a respective sliding block projecting therein, each said respective sliding block being arranged on a shaft coupled to a connecting rod and constructed for a movement of said connecting rod resulting in movement of said second energy store executed in a controlled manner by a sweep of said sliding block in said gate passage.

2. The switching contact drive device according to claim 1 , wherein said store housing directs a relative movement of said energy store.

3. The switching contact drive device according to claim 1 , wherein said transmission has a transmission housing and said store housing is mounted on a mating surface of said transmission housing.

4. The switching contact drive device according to claim 1 , wherein said store housing directs a deformation of said energy store.

5. The switching contact drive device according to claim 1 , wherein said gate passage has brackets bridging said gate passage.

6. The switching contact drive device according to claim 5 , wherein said gate passage is two diametrically opposite gate passages.

7. 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;

a joining point incorporated in said store housing transversely to a relative movement of said energy store, said store housing having a gate passage for guiding a movement of said energy store and said gate passage being disposed transversely to said joining point, said store housing having form-fitting elements, said gate passage being centered in a mating surface by means of said form-fitting elements;
a second store housing having a second energy store and diametrically opposed second gate passages being oriented in a linear profile, said second gate passages each being swept by a respective sliding block projecting therein, each said respective sliding block being arranged on a shaft coupled to a connecting rod and constructed for a movement of said connecting rod resulting in movement of said second energy store executed in a controlled manner by a sweep of said sliding block in said gate passage.

8. The switching contact drive device according to claim 7 , wherein said gate passage has brackets bridging said gate passage.

9. The switching contact drive device according to claim 8 , wherein said gate passage is two diametrically opposite gate passages.
