Patent ID: 8231396

Claim:
A plug-in unit assembly, comprising: a case; and a plug-in unit arranged to be removably connected to the case, the plug-in unit having a plugged-in position and a detached position in relation to the case, the plug-in unit comprising: a unit body; a handle; and an actuating member, the handle being pivotally connected to the unit body for pivoting between a normal position and a mounting position in relation to the unit body, the actuating member being movably connected to the unit body for movement between a locking position and a releasing position in relation to the unit body, the handle being operationally connected to the actuating member such that a pivoting of the handle from the mounting position to the normal position will move the actuating member from the releasing position to the locking position and a pivoting of the handle from the normal position to the mounting position will move the actuating member from the locking position to the releasing position; the case comprising: a locking counterpart element; and a releasing counterpart element, the locking counterpart element co-operating with the actuating member for moving the plug-in unit from an outer plugging position to the plugged-in position in response to a movement of the actuating member from the releasing position to the locking position, the outer plugging position being located at a predetermined plugging distance from the plugged-in position towards the detached position, and the releasing counterpart element being configured for co-operating with the actuating member for moving the plug-in unit from the plugged-in position to an outer releasing position in relation to the case in response to a movement of the actuating member from the locking position to the releasing position, the outer releasing position being located at a predetermined release distance from the plugged-in position towards the detached position, wherein: the actuating member is pivotally connected to the handle through an off-center pivotal connection, the off-center pivotal connection being located at a distance from a pivoting axis of the handle and allowing the actuating member to pivot in relation to the handle, the actuating member is connected to the unit body through a guiding slot connection, the guiding slot connection including a guiding slot provided on one of the actuating member and the unit body, the guiding slot connection being configured for slidingly guiding the movement of the actuating member between the locking position and the releasing position, and the actuating member includes a locking surface for co-operating with the locking counterpart element and a releasing surface arranged to co-operate with the releasing counterpart element, both the locking surface and the releasing surface being located at a distance from the off-center pivotal connection.
