Abstract
A plug-in device system has a closure unit blocking access to a first plug-in device element, for example a socket. The closure unit includes a rotary bezel which is coupled via a coupling to at least one shutter such that the rotation of the bezel effects a movement of the shutter from a closed position in an open position. Preferably, a locking assembly is additionally provided, which blocks movement of the rotary bezel and/or shutter in the closed position as long as no pressure is applied to the shutter. In addition, a safety device can be provided, which prevents the shutter from opening when a direct force is applied.
Claims24
An electrical plug-in device system, comprising:
- a first plug-in device element;
- a second plug-in device element compatible with the first plug-in device element and having a non-circular outside contour, said first plug-in device element and said second plug-in device element configured to be connected in an insertion direction;
- a closure device arranged in front of the first plug-in device element;
- wherein the closure device comprises:
- a) a rotatable bezel having a through-opening having an inside contour which corresponds at least partially to a non-circular outside contour of the second plug-in device element and configured to engage with the second plug-in device element with a form-fitting rotation lock;
- b) at least one shutter movable between a closed position and an open position;
- and
- c) a coupling configured to convert a rotational movement of the rotary bezel into a movement of the shutter from the closed position to the open position.
A closure device for controlling access of a second plug-in device element to a complementary first plug-in device element, comprising:
- a) a rotatable bezel having a through-opening configured to engage with the second plug-in device element with a rotation lock;
- b) at least one shutter movable between a closed position and an open position;
- and
- c) a coupling configured to convert a rotational movement of the rotary bezel into a movement of the shutter from a closed position to an open position.
A method for controlling access of a second plug-in device element to a complementary first plug-in device element, comprising:
- blocking with at least one shutter access to the first plug-in device element when the at least one shutter is in a closed position;
- bringing the second plug-in device element into rotation-locked engagement with a rotary bezel and thereafter rotating the second plug-in device element;
- transferring the shutter by rotating the rotary bezel from the closed position into an open position, wherein the shutter unblocks access to the first plug-in device element;
- and
- inserting the second plug-in device element into the first plug-in device element by movement along an insertion axis.
