Embodiment Construction

[0026] In this application, "coupled" means a connection between two or more elements, whether direct or indirect, as long as a connection occurs.

[0027] In this application, "directly coupled" means that two elements are in direct contact with each other.

[0028] In this application, "fixedly coupled" or "fixed" means that two components are coupled so as to move as one.

[0029] As used herein, "operatively engaged" when referring to a component directly coupled to the cam means that the force applied to the cam by the component is sufficient to cause the cam to rotate.

[0030] In this application, a "pivot point" is a coupling between two or more elements that allows the elements to pivot relative to each other. The pivot point may be, but is not limited to, an opening in each element and a separate rod through which the rod extends, or a rod on a first element and an opening on a second element, Wherein the rod on the first member extends through the opening on the s...

Abstract

The present invention provides for an electrical switching apparatus operating mechanism opening assembly wherein the toggle assembly stop/kicker pin has been separated into a kicker pin and a stop pin. By separating the functions of the stop/kicker pin into separate pins, the kicker pin may now be located at the pivot point of the associated link. Further, the kicker pin and the stop pin are now disposed upon a cradle assembly as opposed to an elongated link. The cradle assembly further supports one of the toggle assembly links. Thus, rotation of the cradle assembly causes the toggle assembly to move. The operating mechanism opening assembly is configured so that, when an associated latch assembly latch plate assembly is released, the cradle assembly rotates so that the toggle assembly is moved away from a closing assembly closing device.

Description

[0001] Cross References to Related Applications [0002] This application is related to commonly assigned U.S. Patent Application Serial No._ / ____, filed concurrently on May 4, 2007, entitled "Electrical Switching Apparatus and Yoke Assembly and Spring Assembly Thereof" (Attorney's Case No. 07-EDP-132), which application is hereby incorporated by reference. technical field [0003] The present invention relates to an electrical switchgear operating mechanism, and more particularly to an electrical switchgear operating mechanism opening assembly having a bracket assembly with a pivot serving as a pusher for a toggle assembly ( kicker). Background technique [0004] Electrical switching apparatus generally includes a housing, at least one bus assembly having a pair of contacts, a trip device, and an operating mechanism. The housing assembly is configured to isolate and encapsulate other components. The at least one pair of contacts includes fixed contacts and movable contac...
