Abstract

A load includes a device for inductively powering it, the device including an insertion part, following the insertion of which into the load the powering of the latter is provided.

First claim

What is claimed is:

1. A device, comprising:
an inductive power device configured to inductively power a load, the inductive power device including an insertion part, the inductive power device configured to power the load after insertion of the insertion part into the load in an insertion direction, wherein the load at least partially contacts the insertion part when connected, and the load prevents movement of the insertion part in at least a first direction, the insertion part having a bore hole extending in a second direction different than the first direction and adapted to align with a corresponding bore hole, extending in the second direction, of the load, the bore hole of the insertion part and the bore hole of the load adapted to receive a bolt and/or a shackle of a lock, in the second direction, to couple the insertion part and the load in a form-locking manner and/or to block insertion of the insertion part into the load;
wherein the insertion part includes at least one elevation extending along the insertion direction, and the load includes at least one track extending along the insertion direction, the at least one elevation being complementary to the at least one track; and
wherein the at least one elevation is adapted to slide along the at least one track when the insertion part is inserted into the load in the insertion direction.

2. The device according to claim 1 , wherein the inductive power device includes a primary conductor adapted to inductively couple to a secondary winding of the load.

3. The device according to claim 1 , wherein at least one primary conductor is arranged in at least one of (a) an indentation and (b) a cable duct of the load.

4. The device according to claim 1 , wherein at least one secondary winding is wound around a U-shaped core.

5. The device according to claim 1 , wherein the load at least one of (a) is impervious, (b) is smooth on an outer surface, and (c) provides a high degree of protection for use in at least one of (a) wet areas and (b) aseptic areas.

6. The device according to claim 1 , wherein the load does not include a plug-and-socket connector or other electrical connection terminals on an exterior.

7. The device according to claim 1 , wherein information is transmittable by modulating higher-frequency signals onto a primary conductor.

8. The device according to claim 1 , wherein the at least one elevation fits into the at least one track to prevent movement of the insertion part in at least a third direction; and
wherein the first direction is different from the third direction.

9. The device according to claim 1 , wherein the insertion part is completely removable from the load.

10. The device according to claim 1 , wherein the at least one elevation fits into the at least one track to prevent movement of the insertion part in at least a third direction;
wherein the first direction is different from the third direction; and
wherein the first direction is substantially orthogonal to the third direction.

11. A system, comprising:
loads powered in a contactless manner by inductively coupling each load to at least one primary conductor;
wherein each load at least partially contacts an insertion part when connected, and the load prevents movement of the insertion part in at least a first direction; and
wherein the insertion part includes a bore hole extending in a second direction different than the first direction and adapted to align with a corresponding bore hole, extending in the second direction, of the load, the bore hole of the insertion part and the bore hole of the load adapted to receive a bolt and/or a shackle of a lock, in the second direction, to couple the insertion part and the load in a form-locking manner to block insertion of the insertion part into the load;
wherein the insertion part includes at least one elevation extending along an insertion direction of the insertion part, and the load includes at least one track extending along the insertion direction, the at least one elevation being complementary to the at least one track; and
wherein the at least one elevation is adapted to slide along the at least one track when the insertion part is inserted into the load in the insertion direction.

12. The system according to claim 11 , wherein primary conductor is removable from the load.

13. The system according to claim 11 , wherein the primary conductor is encapsulated in the load.

14. The system according to claim 11 , wherein the primary conductor is acted upon by medium-frequency, alternating current.

15. The system according to claim 11 , wherein the primary conductor is acted upon by medium-frequency, alternating current of one of (a) approximately 10 to 50 kHz and (b) approximately 20 kHz.

16. The system according to claim 11 , wherein the primary conductor is configured to power the loads in series.

17. The system according to claim 11 wherein at least one of (a) the primary conductor is supplied with energy in a contactless manner via stationary coil cores including at least one coil winding and (b) the primary conductor is supplied with energy via a collector wire.

18. The system according to claim 11 , wherein the primary conductor is arranged as a closed loop.

19. The device according to claim 1 , wherein the at least one elevation fits into the at least one track to prevent movement of the insertion part in at least a third direction; and
wherein the first direction is different from the third direction.

20. The system according to claim 11 , wherein the at least one elevation fits into the at least one track to prevent movement of the insertion part in at least a third direction; and
wherein the first direction is different from the third direction.

21. A device, comprising:
an inductive power device configured to inductively power a load, the inductive power device including an insertion part, the inductive power device configured to power the load after insertion of the insertion part into the load in an insertion direction, wherein the load at least partially contacts the insertion part when connected, and the load prevents movement of the insertion part in at least a first direction, the insertion part having a bore hole extending in a second direction different than the first direction and adapted to receive a shackle of a lock, in the second direction, to block insertion of the insertion part into the load;
wherein the insertion part includes at least one elevation extending along the insertion direction, and the load includes at least one track extending along the insertion direction, the at least one elevation being complementary to the at least one track; and
wherein the at least one elevation is adapted to slide along the at least one track when the insertion part is inserted into the load in the insertion direction.
