CONTROL MECHANISM FOR AUTOMATIC TRIPPING DEVICE AND AUTOMATIC TRIPPING DEVICE COMPRISING THIS MECHANISM Russian patent published in 2014 - IPC H01H71/52 

FIELD: machine building.

SUBSTANCE: control mechanism comprises a resilient member (37) which is operationally connected to a movable contact (20) and includes a variety of elements (31, 32, 33, 34, 35), with at least the first element (31) of them being operationally connected to the second element by a pin-like coupling unit. Each of the first and second elements comprises a pair of side segments (41, 42) which are set opposite to each other and connected by a cross segment. The pin-like coupling unit comprises a pair of pin-like ends (71, 72) each of which extends from one side of the side segment of the first element. The pin-like coupling unit comprises also a pair of mounting seats (61, 62) each of which is provided on the side segment of the second element. Each of the pin-like ends is inserted in the respective mounting seat so that to determine the axis of mutual rotation of the first and second elements. The resilient member is installed so that to provide for a holding force affecting the pin-like ends and being sufficient to keep their conjugation with the respective mounting seats where they are inserted.

EFFECT: higher reliability of a tripping device with simple design which can be easily modified and provided with multiple alterations.
