Abstract
An installation comprises at least one electrical switchgear apparatus a movable mechanism which is interlocked with a device such as an access door by a kinematic transmission cable comprising a flexible sheath and a core designed to slide in the sheath. The ends of the sheath and of the core are respectively fixed to a fixed part of the apparatus and to the movable mechanism by fixing apparatus comprising an end-piece operating in conjunction with the corresponding part of the cable, a housing designed to receive the end-piece, and a locking device with dead point passage designed to oppose insertion of the end-piece in the housing when the force exerted on the locking device in an insertion direction remains lower than an insertion threshold and to enable insertion of the end-piece in the housing when the force exerted on the device means in an insertion direction is greater than the insertion threshold.
