Abstract

The invention relates to a cable coupler comprising a housing that delimits an interior (13) of the cable coupler, sealing off said coupler from the exterior. The housing comprises a cover body (11) and at least one sealing body (12), the or each sealing body (12) being used to introduce cables (14) into the interior (13) of the cable coupler. The interior (13) contains active and/or passive sub-assemblies (15), designed in particular for splicing the cables that have been introduced into the interior. According to the invention, the cover body (11) has at least one opening, to which a heat sink (16) is coupled for dissipating heat from the interior (13) of the cable coupler into the environment.

Description

cable sleeve

The invention relates to a cable sleeve according to the preamble of claim 1.

Cable sleeves for storage and handling of guided in optical waveguide cables, fiber optic cables are in optical fiber cable networks for the protection of splices at joints of two optical fiber cables as well as to protect the light waveguide at branch points or Auftei- switching centers of optical fiber cables. The cable glands must ensure the continuity of the fiber optic cable as if the fiber optic cable is not interrupted. The structured storage and gentle handling of the optical fiber in this case plays a crucial role, so that the transmission characteristics of the light wave conductors are not negatively affected.

are from the product catalog "Accessories for Fiber Optic Networks, Issue 1, page 75, Corning Cable Systems, 2001" designed as inline sleeves and a hood sleeves Cable sleeves known, all sen a housing aufwei- which an interior of the cable sleeve defined and the interior thereof seals to the outside. in the hood sleeves formed cable sleeves, the housing is formed by a hood-like cover and a single sealing body, via which all the cables can be introduced into the interior of the cable sleeve an inline socket has back up. so that in-line joints can be installed in a line with the cables via two seal body for insertion of cables in the interior of the cable sleeve. in the space defined by the housing of the cable sleeve interior conventionally are passive components for connecting, namely for splicing, by in the cables disposed guided light wave conductors, wherein at the sen assemblies to splice is. Are to be arranged in the interior of the cable sleeve in addition to the passive components and active components, so it must be ensured that generated by the active device during the operation of heat from the interior of the cable sleeve can be discharged to the outside. However, this is only inadequately possible with the previously known cable sleeves.

The same problem arises in connection with cable sleeves for copper cables.

On this basis, the present invention is based on the problem to provide a novel cable sleeve. This problem is solved in that the cable sleeve initially mentioned is further developed by the features of the characterizing portion of claim 1. Erfindungemäß, the cover body has at least one opening to which a heat sink is coupled to drain from the interior of the cable sleeve heat to the outside.

In the sense of the present invention in at least one opening of the cover, a heat sink is integrated. On Integrated into the opening of the cover heat sink can be effectively discharged to the outside from the interior of the cable sleeve heat. This makes it possible for the first time, also such an active modules arrival in the interior of a cable sleeve, which generate a large amount of heat during operation. In this way, the application range can be extended by sealing boxes.

Preferred developments of the invention emerge from the subclaims and the following description. Embodiments of the inventions are fertil, without being limited thereto, are explained with reference to the drawing. In the drawing: Figure 1 is a diagrammatic view of a cable sleeve according to the invention according to a first embodiment of the invention. and

Fig. 2 is a schematic representation of a cable sleeve according to the invention according to a second AusführungsbeispieJ the invention.

Fig. 1 shows a schematic view of a cable sleeve 10 formed as a hood sleeve, wherein the cable sleeve 10 has a dome-like cover 11 and a seal body 12, which together form a housing of the cable sleeve 10. The housing or the cover 11 and the sealing body 12 define an interior space 13 of the cable sleeve 10, in which can be inserted through the seal body 12 cable 14 into the interior 13 of the cable sleeve 10 degrees.

In the interior 13 of the cable sleeve 10 active and passive assemblies 15 are positioned, wherein the passive components and in particular the connecting and

serve splicing inducted into the interior 13 of cable fourteenth Then, when the cable 14 are formed as an optical waveguide cable, are in the interior 13 of the cable sleeve 10 splice trays to store splices between the

Cables 14 guided light wave conductors disposed. As active components kön- nen z. B. amplifiers or multiplexers in the interior

13 of the cable sleeve to be positioned 10 degrees.

In the embodiment of FIG. 1 is inserted in a side wall of the cover 11 an opening, coupled with a heat sink 16 or in a heat sink 16 is integrated. Through the heat sink 16. Heat from the interior 13 of the cable sleeve 10 can be discharged to the outside. The heat sink 16 is sealed to the cover body 11, so as to ensure that the interior of the cable sleeve 13 is completely sealed to the outside 10th In the embodiment of Fig. 1, the heat sink 16 is integrated in such a way in the opening of the wall of the cover 11, that the heat sink 16 complements the contour of the cover body 11 in the region of the opening. The material of the heat sink 16 has a greater thermal conductivity than the material of the cover body 11. The cover body 11 is preferably formed from plastic. The heat sink, however, is preferably formed from a metallic material.

In Fig. 1, a fan, in addition to the active and passive assemblies 15 is also 17 are arranged in the interior space 13 of the cable sleeve 10, wherein the fan 17 cools the arranged in the interior 13 of the cable sleeve 10 assemblies 15 characterized that the same air flow in the direction of arrow 18 passes through the active and passive assemblies 15 °. The heat sink is integrated in such a way in the cover body 11, that in the flow direction (arrow 18) of the air flow generated by the fan 17 seen, the heat sink 16 is positioned downstream of the passive and active modules 15 °.

The heat sink 16 preferably occupies between 5% and 50%, especially between 10% and 20%, the surface of the cover 11 a.

Fig. 2 shows a cable sleeve 19 which is mounted in an underground inspection pit 20 via a fastening device 21 on a vertically extending wall of the installation pit 20. The cable sleeve 19 corresponds in construction substantially to the cable sleeve 10, so that used to avoid unnecessary repetition of the same assemblies, like reference numerals.

Also in the embodiment of Fig. 2 is inserted into an opening in a wall of the cover 11, wherein the opening in a heat sink 22 is integrated with the interposition of a flexible intermediate piece 23, which is preferably designed as a flexible hose. The intermediate piece 23 is opposite the one hand, the heat sink 22 and the other sealed to the cover body. 11 Due to the flexibility of the intermediate piece 23, the heat sink can be positioned 22 almost arbitrarily relative to the cover body 11 of the cable sleeve 19, which is mounted in the embodiment of Fig. 2, the heat sink 22 at a the underground installation pit 20 upward final cover 24. Thereby, the heat dissipation from the interior of the cable sleeve 13 can be improved again.
