Abstract

An end closure for a cable having a core, at least two electrical cable wires and at least one optical transmission element, the core is surrounded by a metal wire reinforcement. On the end of the electrical cable wires an electrically suitable connection set is mounted, which at least partially protrudes out of a pipe. A connection unit is mounted on the end of the optical transmission element, which also partially protrudes from the pipe. The connection unit has a pot shaped tension element mounted tension proof on the free end of the pipe and surrounds, moisture tight and pressure tight, the part of the connection set and the connection unit that protrudes out of the pipe.

First claim

The invention claimed is:

1. End closure for a cable, the cable having a core that has at least two electrical cable wires for the transmission of electrical energy and having at least one optical transmission element, said end closure comprising:
a reinforcement composed of metal wires surrounding the core, wherein
the metal wires of the reinforcement on an end of the cable are distanced a predetermined length,
an end of the core of the cable is surrounded by a tension proof pipe that is connected tension proof with the remaining reinforcement,
on an end of the electrical cable wires, to directly connect electrical couplings, an electrically suitable connection set is mounted, which at least partially protrudes out of the pipe,
a connection unit, one equipped with a part of a plug connector, is mounted on an end of the optical transmission element, which also partially protrudes from the pipe, where the connection unit is fastened in, and rotatably attached to, a holder that has a turning point, around which the holder can be turned or pivoted; and
a pot shaped tension element mounted tension proof on a free end of the pipe, surrounds, moisture tight and pressure tight, a part of the connection set and the connection unit that protrudes out of the pipe.

2. End closure according to claim 1 , wherein the tension proof connection between the pipe and the reinforcement on one side, as between the tension element and the pipe on the other side, is carried out moisture proof and pressure tight.

3. End closure according to claim 1 , wherein the connection sets are supported in a radial direction in the pipe.

4. End closure according to claim 1 , wherein, on an outside of the pipe, is mounted a part, a fastening device for securing the pipe to a fixed plant.

5. End closure according to claim 1 , wherein on a free end of the tension element a drawbar is mounted.
