Description

Area- techniques

BACKGROUND OF THE INVENTION The present invention relates to a sleeve for connecting two ends of an outer braided conductor to a light guide (LFS), comprising:

- a sleeve of a sleeve which in its interior surrounds the connecting space and comprises at least holding means for at least one LWL cassette

a current - conducting connection between the two ends of the outer fiber - optic cable (LFS); and

- tensioning means for each end of the outer stranded conductor (LFS),

BACKGROUND OF THE INVENTION

Coupling sleeves are known which can be used in the free span of outer stranded conductors with light guides or in the area of the anchor mast. In the region of the anchorage mast, there is generally a possibility of placing or hanging the connecting sleeve on the insulating device and conducting the light guide to the ground potential in the insulating device. In doing so, it is achieved that the sleeve did not absorb the tensile force of the ends of the stranded conductors.

To date no coupling sleeves of this kind are known which are not designed as insulating devices and are suitable for leading at least one light guide from the sleeve.

SUMMARY OF THE INVENTION It is an object of the invention to provide a connecting sleeve which is not only suitable for connecting stranded conductors transmitting traction, but is also designed to lead at least one

LWL.

SUMMARY OF THE INVENTION

The task according to the invention of the ends of outdoor plaited includes:

- a sleeve of a sleeve that surrounds the connecting space in its interior and comprises at least holding means for at least one LWL-cassette

- the current conductive connection between the two ends of the outdoor light-conducting (LFS) conductors (LFS), and

- tensile force retention means for each end of the outer stranded conductors (LFS), the nature of which is that there is at least one bushing in the sleeve of the sleeve for at least one branch of the light guide.

Further embodiments can be found in the subclaims.

The connecting sleeve may be formed with different features and / or in different embodiments.

The sleeve of the sleeve is perpendicular to the direction of connection of the outer braided conductors divided into at least two housing sub-bodies and at least one bushing is (only) formed in one of the two housing sub-bodies.

The sleeve of the sleeve is formed of two - preferably almost identical - housing subassemblies and there is at least one bushing in only one housing subassembly.

In one housing part body at least one bushing is formed between the two housing part bodies standing at the end.

solves a sleeve for connecting two conductors with light guides (LFS), which

The grommet may be formed either substantially perpendicular or substantially parallel to the direction of connection of the outer stranded conductor to the light guides. The light guides are usually threaded through the LWL tube. Stainless steel tubes have proved to be the most robust LWL tubes. The discharge of the LWL tube is carried out by known measures, wherein the LWL tube is provided with care for at least moisture tightness and strain relief. The LWLs are then routed to the insulators independent of the connection sleeve and come above them to earth potential.

Furthermore, the grommets can be so designed that, when not in use, they can be closed off by means of closing means (lids or screws), also with a minimum requirement for moisture tightness.

The sleeve of the sleeve may be divided into several housing housings along or transverse to the direction of connection of the outer braided conductors to the light guides. The sleeve of the sleeve may also be constructed substantially symmetrically about an axis of rotation.

The ends of the outer stranded conductor are fastened in the sleeve housing by means of fastening means - such as crimped couplings, cable ties or cable screw connections - in a tensile manner.

The sleeve of the sleeve is constructed in such a way (e.g. as a full metal sleeve) that it can assume the electrical connection of the outer stranded wires. To this end, it is provided that the outer braided conductors are fastened to the sleeve of the sleeve in an electrically conductive manner via the power supply pins. The introduction of the outer stranded conductors through the power supply pins into the sleeve of the sleeve must therefore take place in such a way that no insulating layers (for example, no silicone lubricant) can lie between them.

The outer sleeve of the sleeve may be a power rail for electrically bridging the sleeve of the sleeve. Such an embodiment is shown when the sleeve of the sleeve is made of plastic, or the electrical conductivity of the sleeve of the sleeve is not sufficient for the (complete) transmission of electrical energy,

There may be fastening means on the connecting sleeve for hanging the sleeve of the sleeve, for example on an anchor mast.

DETAILED DESCRIPTION OF THE INVENTION

Giant. 1 shows a sleeve for connecting a pair of ends of the outer stranded wires to the LFS fiber optics. Giant. 2 shows a view of the sleeve of the sleeve in the 90 ° position relative to the view of FIG. 1. The sleeve comprises a sleeve 24 of sleeve that includes at its interior a connecting space 52 and at least a holding member (34, 35, 36) in the connecting space. at least one

The LWL-cassette 38. The sleeve sleeve 24 surrounds the complete connecting space 22, which comprises at least one (two in FIG. 1) LWL-cassettes 38. The sleeve sleeve 24 is formed of two sleeve sub-bodies 24.1, 24.2 that are divided perpendicularly to the direction of connection of the outer stranded conductor and which meet at the gap 25 to form a flange there. By dashed line 252 it is indicated that the sleeve 24 of the sleeve can be divided into more

By dividing into three parts, end portions of the housing could be formed, and a central middle portion the middle portion could be two pieces. both identical to form a connecting space, in such an embodiment comprising one or more bushings for the LWL; the housing end pieces have no grommets.

An electrical conductive connection exists between the two ends of the fiber optic LFS outer braided conductor. This can take place through the electrically conductive outlets of the outer stranded conductor through the metal sleeve of the sleeve, or bypassing the current circuit through the sleeve from the cable clamps 100 and power supply pins 70 through a power rail connecting the power supply pins 70 from both sides. A suspension eye 19 may be disposed on the power rail 18 to accommodate the pulling force of the hanging sleeve. The LWLs pass through the inlets of the outer stranded conductor in the sleeve sleeve to the connecting cassettes 38 via the leads 20 ..

To lead the light guides from one of the housing sub-bodies 24.1, 24, two bushings 30, 31 are present which are allowed to close tightly to moisture.

Giant. 3 shows the sleeve of the sleeve in cross-section. The electrically conductive connection to the metal sleeve 24.1, 24.2 of the sleeve is made of a power supply.

from sleeve transition. 20.1 in which it is

At this point (soldered or modified that there is a good outdoor conductor consists of a stranded conductor clamped by a screw connection 203.

Reference numeral 20.2 represents round sealing rings which are coated with silicone. The connecting space (right and left) is formed by two axial f

plates 33, which are screwed together by flange connection 34. The flange connection 34 furthermore constitutes a carrier for the LWL-cassettes 38. Several cassettes are held together and supported by means of pins 35 and 36. Otherwise, the design of the connecting space is comparable to that of DE 91 15 949.0 U1.

Giant. 4 shows (as seen in FIG. 2) a sleeve of a sleeve in which the LWL bushings 30 are arranged parallel to the direction of connection of the outer stranded conductor. The sleeve of the sleeve is therefore designed with a larger diameter than the previously mentioned embodiments.

Giant. 5 shows a two-piece sleeve (24.1, 24.2) in which the inner space is constructed relatively small. The connecting flange 28 of the two housing parts projects outwardly over the diameter of the sleeve of the sleeve. As can be ascertained by comparison with FIG. 3, the connecting flange 28 is designed narrow only. as necessary to position the flange connection bolts 26. The construction otherwise corresponds to the illustration in Fig. 3.

FIG. 6 shows an embodiment where the power rail 18 is divided into two (18.1 and 18.2). The inner ends of the two power rail parts are physically connected to the two flange halves 28.1 and 28.2 (e.g. by welding). The sleeve sleeve gains great stability by this connection.
