Actuating device for a power cut-off or disconnection system

Abstract

Actuating device of a power interruption or disconnection system Actuating device (20) of a power interruption or disconnection system (10) comprising an actuating shaft (22) movable in translation about a principal axis between a closed position and an open position; a locking device (30) comprising at least a first locking finger (31,31') movable in translation about a first axis of displacement (Y1) having a beveled end portion (51) defining at least a first inclined plane surface (52,52') whose normal (n1) extends in a plane (P) parallel to the first axis of displacement and to the principal axis, said first inclined plane surface being oriented towards a first end portion or a second end portion of the actuating shaft;and a first cam (60) fixedly mounted relative to said actuating shaft and having a peripheral part (66) in which is formed at least one first ramp (74) parallel to said first inclined flat surface, the locking device being able to take at least one locking configuration in which said first locking finger is pushed towards said first cam so that said first inclined flat surface cooperates by planar contact with said first ramp in order to hold the actuating shaft in the closed position or in the open position.
