Abstract

An end piece for a fiber-optic cable, with a sheath and strength members. An insert of the end piece has a rear hollow cylindrical attachment. The attachment has a rear end section with an outer swelling and a section nearer the front, which is free from the sheath. An end of the sheath is pushed onto the end section over the swelling. The section towards the front is covered by the strength member, which project from the sheath end. A common sleeve 6 is applied to the attachment in such a way that it fixes both the end of the sheath on the end section and the strength members on the section towards the front.

an insert with a rear hollow attachment having;

a rear end section formed with an outer swelling adapted to receive thereon an end of a cable sheath of a fiber-optic cable; and

a section forwardly adjacent said rear end section in a plug-in direction of the fiber-optic cable that remains free from the cable sheath but is covered by strength members of the fiber-optic cable that project beyond the cable sheath end; and

a sleeve disposed on said rear hollow attachment and embracing and fixing the end of the cable sheath to said swelling of said rear end section and the strength members to said section forwardly adjacent said rear end section.

2. The end piece according to claim 1, wherein said sleeve is a crimping sleeve crimped onto said rear end section with the cable sheath interposed between said crimping sleeve and said rear end section, and crimped onto the section forwardly adjacent said rear end section with the strength members interposed between said crimping sleeve and said section forwardly adjacent said rear end section.

3. The end piece according to claim 1, wherein said sleeve is disposed forward of said swelling in the plug-in direction.

4. The end piece according to claim 1, which further comprises an anti-kink sleeve pushed onto an end of said sleeve facing toward a front of the end piece in the plug-in direction.

5. The end piece according to claim 4, wherein said anti-kink sleeve is rotatably mounted on the end of said sleeve facing toward the end.
