Claim:
A plug-in unit assembly comprising a case and a plug-in unit arranged to be attached thereto, the plug-in unit comprising at least one electrical component having at least one connector, and the case comprising at least one connector arranged to be coupled to the connector in said plug-in unit when the plug-in unit is attached to the case, the plug-in unit assembly also comprising locking means having a locking position and an unlocked position, the plug-in unit being locked substantially immovably to the case when the plug-in unit is attached to the case and the locking means are in the locking position, and the plug-in unit being detachable from the case when the locking means are in the unlocked position, the plug-in unit comprising handle means that are pivoted to turn around a pivoting axis and comprise a release handle arranged for turning the handle means around the pivoting axis, and the handle means having a normal position and an unlocking position for the locking means, the turning of the handle means to the unlocking position for the locking means causing the moving of the locking means to the unlocked position when the plug-in unit is locked into the case, wherein the handle means also have a position for detaching the plug-in unit, whereby the turning of the handle means further from the unlocking position for the locking means to the position for detaching the plug-in unit causes the plug-in unit to move along a predetermined distance outwards from the case, and wherein the locking means comprise at least one movable lock part provided with spring means, and at least one means for using the movable lock part and arranged to function with the lock part in a manner enabling the movement of the lock part by moving the means for using the lock part, and wherein said at least one lock part is integral with said at least one means for using the lock part, and wherein said assembly constituted by the lock part and the means for using the lock part is arranged to move substantially in parallel in relation to the pivoting axis of the handle means.
