Problems solved by technology

[0004] The disadvantage of the known rotor housing is that it is limited in its complexity when manufactured in one part
If a two-part housing is required, it must be cost-intensive to ensure the support of the housing interior and the locking of the housing
This requires not only additional assembly steps but also a high level of complexity for the structural design of the individual housing elements

Embodiment Construction

[0064] figure 1 with 2 A first embodiment of a rotor housing 10 according to the invention is shown. The rotor housing 10 has two housing elements 20a and 20b, for example figure 2 can be separated from each other as shown. Furthermore, a connecting element 30 is provided, the shaft section 32 of which passes through the interior of the rotor housing 10 , ie the housing interior 22 . As a result, the shaft section 32 is located in the housing interior 22 , for example Figure 4 The swivel support structure forming part of the breaking mechanism 110 as shown in FIG.

[0065] To locally fix the two housing elements 20 a and 20 b relative to one another, the connecting element 30 has a head section 37 and a base section 38 . The head section 37 and the base section 38 each have a contact surface 39 which bears on the outer side of the respective housing element 20a and 20b. if available in Figure 3a with 3b As seen in , since the connecting element 30 has a mounting mea...

Abstract

The housing (10) has a housing element (20a) and another housing element (20b) that together forms a casing interior (22) for receiving of an opening mechanism. A connecting element (30) is utilized for locally connecting the former housing element and the latter housing element with each other. The connecting element has a shaft section (32) for rotary storage of a part of the opening mechanism. The connecting element comprises a set of opposite ends (30a, 30b) and a set of bearing units (34a, 34b). Independent claims are also included for the following: (1) a switching device (2) a method for assembly of a switching device.

Description

technical field [0001] The invention relates to a rotor housing for an opening mechanism of an electrical switching device, in particular a switching device for a circuit breaker, a switching device for an electrical switching device, such an electrical switching device and for mounting a switching device Methods. Background technique [0002] It is known to provide disconnecting mechanisms for electrical switching devices, in particular circuit breakers, in order to provide automatic disconnection of electrical circuits in a desired manner. Such electrical switching devices are also used, for example, as fused short-circuiters. In this case, the disconnection mechanism generally has a contact bridge or a plurality of contact bridges, which are movable between a contacted position state and a non-contact position state. The disconnecting mechanism is here movable between these two positions, that is to say between an on position and an off position, so that a corresponding...
