Multi-part housing and device for locking interconnected housing parts of a multi-part housing

In combination with a multi-part housing configured to accommodate electric components and electronic components, the multi-part housing having a first housing part and at least a second housing part, the first housing part having an opening formed therein and an outer wall and being connectable to the second housing part, the opening in the first housing part being a slot-shaped opening defining a longitudinal direction, the slot-shaped opening having lateral borders extending substantially parallel to one another, a device for locking the first housing part and the second housing part to one another, the device comprising:

• a locking element being shaped for and disposed in the slot-shaped opening, said locking element being configured to be movable between a locking position and an unlocking position, said locking element having given parts configured to be in contact with sections of the lateral borders;
• said locking element having an actuating surface adjacent the outer wall of the first housing part and having a sliding and arresting body extending through the slot-shaped opening, said sliding and arresting body being a hollow body having wall sections, parts of said wall sections forming sliding elements extending parallel to and abutting against the lateral borders of the slot-shaped opening in the first housing part;
• said locking element, in the locking position, connecting the first housing part to the second housing part in at least one of a form-locking and a force-locking manner;
• said locking element, in the unlocking position, releasing a connection between the first housing part and the second housing part;
• and
• a blocking element connected to said locking element, said blocking element blocking said locking element from being adjusted at least in the locking position, said blocking element operably placing said given parts of said locking element into force-locking abutment against the sections of the lateral borders of the slot-shaped opening.

A multi-part housing configuration, comprising:

• a first housing part and at least a second housing part, said first housing part having an opening formed therein and being connectable to said second housing part, said opening in said first housing part being a slot-shaped opening defining a longitudinal direction, the slot-shaped opening having lateral borders extending substantially parallel to one another;
• a locking element disposed in said slot-shaped opening and having given parts configured to be in contact with sections of the lateral borders, said locking element being configured to be movable in the longitudinal direction between a locking position and an unlocking position and being displaceable in the longitudinal direction between the locking position and the unlocking position;
• said locking element, in the looking position, connecting said first housing part to said second housing part in at least one of a form-locking and a force-locking manner;
• said looking element, in the unlocking position, releasing a connection between the first housing part and the second housing part;
• and
• a blocking element disposed in said locking element, said blocking element blocking said locking element from being adjusted at least in the locking position and operably disposing said given parts of said locking element into force-locking abutment against the sections of the lateral borders of the slot-shaped opening.
