Abstract

A cable sheath of cable end piece is partially removed, exposing at least one signal conductor and the ends of an elongated stress-relief device. The cable end piece is inserted through inlet orifice into a container. A spreading sleeve is inserted into the end of the cable sheath, thus spreading out the ends of the stress-relief device and therefore widening the cable sheath beyond the cross section width (or diameter) of the inlet orifice.

Claims

1. A receptacle arrangement for an end piece of a cable, said arrangement comprising:

a cable including a cable sheath enclosing at least one signal conductor and an elongated stress-relief device, said cable having an end piece such that an end of the cable sheath at the end piece of said cable is sufficiently removed to expose at least one of said signal conductors and an end of said stress-relief device;

a container having an inlet orifice, such that the end piece of said cable is inserted into said inlet orifice, and an outlet orifice, such that at least one of said signal conductors exits through said outlet orifice;

a casting compound inside said container such that said casting compound surrounds at least one of said signal conductors, the end of said stress-relief device and at least a portion of said cable sheath in said container;

a spreading body that is at least partially inserted into the portion of said cable sheath in said container, said spreading body spreading out the end of said stress-relief device, said spreading body is dimensioned so that a diameter of the end of said cable sheath in said container is widened beyond the diameter of the inlet orifice of said container.

2. The receptacle arrangement of claim 1 wherein said casting compound is at least one of a light-activated and a light-curing resin system.

3. The receptacle arrangement of claim 2 wherein said container is made of a transparent material.

4. The receptacle arrangement of claim 3 wherein said spreading body is made of a transparent material.

5. The receptacle arrangement of claim 4 wherein in said spreading body has an essentially oval and hollow internal cross-section.

6. The receptacle arrangement of claim 3 wherein in said spreading body has an essentially oval and hollow internal cross-section.

7. The receptacle arrangement of claim 3 wherein the inlet orifice of said container has a profiled inside contour with teeth that press into an outer material of said cable sheath.

8. The receptacle arrangement of claim 3 wherein the inlet orifice of said container is surrounded by an anti-kink sleeve that extends away from said inlet orifice, said anti-kink sleeve is an integral part of said container.

9. The receptacle arrangement of claim 2 wherein said spreading body is made of a transparent material.

10. The receptacle arrangement of claim 9 wherein in said spreading body has an essentially oval and hollow internal cross-section.

11. The receptacle arrangement of claim 2 wherein in said spreading body has an essentially oval and hollow internal cross-section.

12. The receptacle arrangement of claim 2 wherein the inlet orifice of said container has a profiled inside contour with teeth that press into an outer material of said cable sheath.

13. The receptacle arrangement of claim 2 wherein the inlet orifice of said container is surrounded by an anti-kink sleeve that extends away from said inlet orifice, said anti-kink sleeve is an integral part of said container.

14. The receptacle arrangement of claim 1 wherein said signal conductor is at least one optical fiber.

15. The receptacle arrangement of claim 1 wherein in said spreading body has an essentially oval and hollow internal cross-section.

16. The receptacle arrangement of claim 1 wherein the inlet orifice of said container has a profiled inside contour with teeth that press into an outer material of said cable sheath.

17. The receptacle arrangement of claim 1 wherein an inside wall of said container, running in an axial direction of the end of said cable, is roughened.

18. The receptacle arrangement of claim 17 wherein an inside wall of said container, running in an axial direction of the end of said cable, is profiled.

19. The receptacle arrangement of claim 1 wherein an inside wall of said container, running in an axial direction of the end of said cable, is profiled.

20. The receptacle arrangement of claim 1 wherein the inlet orifice of said container is surrounded by an anti-kink sleeve that extends away from said inlet orifice, said anti-kink sleeve is an integral part of said container.
