Hooking device for electric control mechanism aparataje and control mechanism equipped with such a device.

摘要

Coupling device for the control device, particularly for medium voltage switch, comprising: - a wheel (10) rotatably mounted command on a first shaft (11) so restricted according to a certain direction of rotation and having a surface forming surface (12) cam, - a finger (20) locking rotatably mounted along a second axis (21) and having a portion (23) forming a stop and a follower portion (22) cam intended to contact said surface (12) cam; characterized by: - ​​a guide (30) comprising a portion (31) stop; being capable device occupy a restrained configuration in which said wheel (10) command is immobilized in rotation: - firstly, for the support of said follower portion (22) of cam portion (13) lock said surface (12) of cam, and - on the other hand, for the immobilization in rotation of said finger (20) via retention of the part (23) forming a stop for said portion (31) abutting the guide ( 30); said device being designed to be released from its configuration bolted by a start movement of the guide (30) that causes an exhaust cap between said portion (23) forming a stop and said portion (31) abutting the guide (30 ), and becomes free in rotation of said finger (20) along the second axis (21), driving said exhaust top to a start rotation of the wheel (10) under the effect of its restriction, pushing the follower portion ( 22) cam to detach said portion (13) of the locking surface (12) cam moving relatively to this, thanks to the rotation of said finger (20) along the second axis (21).
