Abstract

A strain relief facility for a coaxial cable that is connectable to an electronics unit via an associated plug, includes two half-shells forming a receiver for the coaxial cable and the associated plug, and a fastening facility to fasten the strain relief facility to the electronics unit, and to fasten the half-shells to one another. The receiver has at least one cable section to receive the coaxial cable and a plug section to receive the plug.

First claim

What is claimed is:

1. A strain relief device for a coaxial cable that is connectable to an electronics unit via an associated plug, the strain relief device comprising:
two half-shells forming a receiver for the coaxial cable and the associated plug, the receiver having at least one cable section configured to receive the coaxial cable and a plug section configured to receive the associated plug; and
a fastening device configured to
fasten the strain relief device to the electronics unit, and
fasten the two half-shells to one another,
the fastening device including a first fastener configured to fasten at least one of the two half-shells to the electronics unit, a first feed-through opening of the first fastener being aligned perpendicular to a plug direction of the associated plug.

2. The strain relief device as claimed in claim 1 , wherein the two half-shells include an electrically conductive material; and
the at least one cable section includes
a first cable section configured to receive an insulated portion of the coaxial cable, and
a second cable section configured to receive a stripped portion of the coaxial cable, such that an outer conductor of the coaxial cable contacts the electrically conductive material.

3. The strain relief device as claimed in claim 2 , further comprising:
at least one contact surface configured to electrically and conductively contact an electrically conductive housing of the electronics unit.

4. The strain relief device as claimed in claim 2 , wherein the two half-shells are configured as a sheath wave barrier in at least one transmission frequency range.

5. The strain relief device as claimed in claim 2 , wherein the first cable section and the second cable section form an axially symmetrical cable run to the associated plug.

6. The strain relief device as claimed in claim 1 , wherein the fastening device comprises:
a second fastener configured to fasten the two half-shells to one another, the second fastener being separate from the first fastener.

7. The strain relief device as claimed in claim 6 , wherein
the first fastener has screws with associated feed-through openings or recesses in at least a lower one of the two half-shells, the associated feed-through openings of recesses including the first feed-through opening; and
the second fastener has screws with associated screw receivers in the two half-shells.

8. The strain relief device as claimed in claim 1 , wherein
edges of an entry opening for the coaxial cable into the strain relief device are rounded off in a region of the entry opening to facilitate a bending radii of the coaxial cable.

9. A connection arrangement comprising a coaxial cable with an associated plug and the strain relief device as claimed in claim 1 .

10. The connection arrangement as claimed in claim 9 , wherein the associated plug is an SMP plug.

11. The connection arrangement as claimed in claim 9 , wherein the coaxial cable is semi-flexible.

12. A medical device having at least two opposably movable components, each of the at least two opposably movable components having at least one electronics unit, and the medical device comprising:
at least one connection arrangement as claimed in claim 9 , the at least one connection arrangement configured to connect the at least one electronics unit in each of the at least two opposably movable components to one another.

13. The medical device as claimed in claim 12 , wherein the at least one connection arrangement comprises at least one contact-free data transmission device.

14. The medical device as claimed in claim 12 , wherein the medical device is a computed tomography device.

15. The strain relief device of claim 1 , wherein the coaxial cable is a moveable coaxial cable.

16. The strain relief device of claim 2 , wherein the electrically conductive material is a metal.

17. The strain relief device of claim 2 , wherein the second cable section is a central cable section.

18. The strain relief device of claim 4 , wherein the at least one transmission frequency range includes a frequency range between 17 and 30 GHz.

19. The connection arrangement of claim 10 , wherein the SMP plug is a snap-in SMP plug.

20. The strain relief device as claimed in claim 3 , wherein the two half-shells are configured as a sheath wave barrier in at least one transmission frequency range.

21. The strain relief device as claimed in claim 3 , wherein the first cable section and the second cable section form an axially symmetrical cable run to the associated plug.

22. The strain relief device as claimed in claim 4 , wherein the first cable section and the second cable section form an axially symmetrical cable run to the associated plug.

23. The strain relief device as claimed in claim 2 , wherein the fastening device comprises:
a second fastener configured to fasten the two half-shells to one another, the second fastener being separate from the first fastener.

24. The strain relief device as claimed in claim 4 , wherein the fastening device comprises:
a second fastener configured to fasten the two half-shells to one another, the second fastener being separate from the first fastener.

25. The strain relief device as claimed in claim 3 , wherein the fastening device comprises:
a second fastener configured to fasten the two half-shells to one another, the second fastener being separate from the first fastener.
