Locking mechanism for a housing to hold a plug-in module

1. A locking mechanism for a housing to hold at least one plug-in module having feet, the locking mechanism comprising:

an actuating mechanism for unlocking feet of a plug-in module,

a lifting mechanism which is connected to the actuating mechanism,

at least one inclined lifting surface on the lifting mechanism to lift a plug-in module held in a housing when unlocking,

wherein the actuating mechanism is movable by translation for unlocking, and

wherein the actuating mechanism forms a single piece with at least one locking element.

2. The locking mechanism according to claim 1 , wherein at least one lifting surface presents at least two areas with different slopes or designed in the shape of curves, to control lifting.

3. The locking mechanism according to claim 1 wherein the actuating mechanism is preloaded with a spring in a locking position.

4. The locking mechanism according to claim 1 wherein the actuating mechanism is substantially rod-shaped, and presents in each case at least one locking element in the vicinity of ends of the locking mechanism.

5. A housing comprising

at least one module holder to hold at least one plug-in module; and

a locking mechanism adapted for locking and unlocking a held plug-in module and comprising:

an actuating mechanism,

a lifting mechanism which is connected to the actuation mechanism,

at least one inclined lifting surface to lift a plug-in module held in the housing when unlocking,

wherein the actuating mechanism is movable by translation for unlocking, and

wherein the actuating mechanism forms a single piece with at least one locking element.

6. The housing according to claim 5 wherein at least one lifting surface presents at least two areas with different slopes or designed in the shape of curves, to control lifting.

7. The housing according to claim 5 wherein the actuating mechanism is preloaded with a spring in a locking position.

8. The housing according to claim 5 wherein the actuating mechanism is substantially rod-shaped, and presents in each case at least one locking element in the vicinity of ends of the locking mechanism.

9. The housing according to claim 5 , wherein the locking mechanism presents in each case two laterally separated locking elements at both ends of the module holder.

10. The housing according to claim 5 comprising a circuit board within the housing which presents electrical plug-in connectors which are arranged on the module holder.

11. The housing according to claim 5 wherein the actuating mechanism presents a pocket to be able to actuate the actuating mechanism with an actuating element.

12. The housing according to claim 5 wherein a counter bearing is provided for the application of the actuating element.

13. A modular system with a housing and at least one plug-in module held on it and with at least one locking mechanism according to claim 1 wherein the locking mechanism is arranged on the housing or on the plug-in module.

14. The modular system of claim 13 wherein at least one lifting surface presents at least two areas with different slopes or designed in the shape of curves, to control lifting.

15. The modular system of claim 13 wherein the actuating mechanism is preloaded with a spring in a locking position.

16. The modular system of claim 13 wherein the actuating mechanism is substantially rod-shaped, and presents in each case at least one locking element in the vicinity of ends of the locking mechanism.

17. The locking mechanism of claim 1 wherein the actuating mechanism is movable by rectilinear movement for unlocking.

18. The housing of claim 5 wherein the actuating mechanism is movable by rectilinear movement for unlocking.

19. The locking mechanism of claim 1 wherein the actuating mechanism is movable in only one translational direction for unlocking.
