Longitudinally split cable sleeve with cable fan-off

When installing cable sleeves, especially sleeves for communication cables, care must be taken that the on tensile, compressive and torsional stresses exerted on the cable entry not detrimental to those in the cable sleeve the splices located. For this purpose, so-called cable clamps are provided which allow rotation or prevent displacement of the cable inserted into the cable sleeve.

The innovation deals with a liQ ^ s -ivided, sealed with plastic material and itL · '; a cable sleeve provided with a cable sleeve, the half-shell of which consists entirely or predominantly of plastic and which has two or more cable entry nozzles at least at one end. According to the innovation is the cable strain relief, the comprising at which two or more / Cabeleinfuhrungsstutzen end of the cable sleeve is provided, each cable supporting ring used and from a the expanded sheath of each of one widened between the core and ä.p ~ <sheath together at the Support ring pressing two-part clamp; this clamp is mounted in a form-fitting manner with the aid of lugs provided in the half-shells; their parts are screwed together using a resilient member, for example a plate spring.

The innovation creates a longitudinally split cable sleeve in which several cables inserted into the sleeve at one end intercepted with a single clamp. The two-part The clamp with which this clamping takes place is made with the help of a

resilient member screwed, so that the clamping connection is long-lasting is. Due to the torsion-proof mounting of the clamp in the socket housing with the help of pressed into the socket housing Noses get a good use of the Muffenrauinca.

To adapt the new cable clamp to different cable diameters a spacer ring can be provided between the respective cable jacket and the two-part clamp. V / continue it is recommended to use the respective support ring and for a better mechanical connection between the • cable jacket and the cable clamp to wave the two-part clamp and, if necessary, the respective spacer ring in the axial direction of the intercepted cable.

An embodiment of the new longitudinally divided cable sleeve and further details of the innovation are explained in more detail with reference to FIGS.

1 shows in section one end of the cable sleeve 1 composed of the two half-shells 20 and 30, in which the communication cable 2 is secured against tensile, compressive and twisting loads with the help of the cable clamp 6. The half-shells 20 and 30 of the cable sleeve are made of plastic and are lined on the inside with the metal foil 11 as a moisture barrier.

FIG. 2 shows a top view of the lower half-shell 30 with the fully assembled cable clamp 6.

Of the two cables that go into the end of the cable sleeve shown 1 can be introduced, only the cable 2 is shown to simplify the drawing. This cable is in the inlet socket 3 with the help of the slipped onto the cable sheath washers 4 made of polyethylene, which grind into grooves on the inside of the filling nozzle 3, and the plastic sealant provided between these disks 5 sealed. To secure the introduction of the

Message cable 2 in the cable sleeve 1 against tension, pressure and The cable clamp 6 is used for torsional stresses Cable support belongs to the support ring 7, which is for each in the cable sleeve The cables to be introduced must be provided once for each. This stud ring is located between the unspecified cable core and the with the help of axially extending cuts through Formation of flaps widened cable jacket 8. The cable jacket O is with the insertion of the radially slotted spacer ring 9 of the two-part clamp 10 is pressed onto the support ring 7. The spacer ring 9 is used to adapt the cable diameter in question independent inner diameter of the two-part clamp 10 to different cable diameters.

The upper part 12 and the lower part 13 of the clamp 10 are means the screw 15 and a nut, not shown, are screwed together. Between the screw head and the upper part 12 of the Clamp 10, the plate spring 16 is provided, through whose spring action a sufficient clamping connection of the cable jacket 8 with the cable clamp 6 even with temperature fluctuations and with Cold flow of the cable jacket material is ensured.

The cable clamp 6 is on the two-part clamp 10 with the help of the lugs 17 in the half-shells 20 and 30 of the cable sleeve 1 are provided and which engage in the parts of the clamp 10 provided with the ribs H, supported in a form-fitting manner.

For better mechanical and, if necessary, electrical connection of the cable jacket 8 with the cable clamp 6 are the support ring 7, the two-part clamp 10 and the spacer ring 9 corrugated in the axial direction of the intercepted cable 2. The support ring 7 also has outwardly directed prongs 18 which are worked out of the support ring, for example by punching, and are used to fasten the screen through connection 19, Via which the cable jacket 8 is electrically conductively connected to the jacket of the cable introduced at the other end of the cable sleeve is.

As can be seen in particular from Fig. 2, the two-part clamp 10 is designed as a double clamp, i.e. by means of the screw-in connector the clamp parts 12 and 13 can simultaneously connect two cable sheaths to the cable clamp 6 and thus against Tensile, compressive and torsional loads are secured.

With the new longitudinally split cable sleeve, all forces occurring on the cable inserted into the cable sleeve are transmitted from the respective cable sheath to the sleeve housing. The new cable sleeve is suitable for cables with a metal jacket as well as for cables with a plastic jacket or with a so-called layered jacket, in which thin metal layers are embedded in a plastic jacket or in which a thin metal layer is provided below a plastic jacket,
