Definitions

  • the invention relates to a cableway connection according to the features of the protection claim 1.
  • the structured cabling is part of the technical infrastructure of a property and is divided into primary, secondary and tertiary areas.
  • High demands are placed on communication cable systems with increasing data volume and increasing transmission rates.
  • Large cable harnesses converge on distribution cabinets for buildings and floor distributors. In the distribution cabinets are often elements of active network technology, eg. As switches, hubs and telephone systems housed.
  • Cable strands are often bundled through cable ducts. These are U-shaped sheet metal profiles with open-topped cross-section, which are mounted by angular support on a wall or suspended under a ceiling. The cableways have various breadboard to order to be coupled together and to be connected to supporting structures can.
  • a network cable consists of four pairs twisted together in pairs, which are shielded in pairs and are also protected by an outer shield. If the wires are displaced with respect to each other or if the shielding is damaged by too small bending radii, the damping of the respective cable increases, so that the requirements for high-speed data transmission may no longer be met.
  • the manufacturer states that a bend radius, measured on the flat side, must not be less than 60 mm. For a permanently installed cable, the bending radius must not be less than 30 mm.
  • the lower cables are pressed against the upper edge of the side wall by the cables above. It can lead to internal displacements of the wires, because the lower cable to be squeezed too much, even if the permissible bending radii of at least 30 mm are still respected. It can also after installation subsequently by settlement operations impairments occur that are not recognized in the usual installation of network cables initially. One possibility for this could also be the only firm tightening of the cable clamps, the cable within the fixed cable bundle by its own weight over time slip down so that the selective pressure on cables that come into contact with the upper edge of the cableway increases ,
  • the present invention seeks to provide a cableway connection, which allows the contracted with the structured cabling companies to use standardized cable trays and at the same time to make the deflection of the cable from the cableway so reliable that even in the long term with an impairment of Data transmission speed is to be expected.
  • the cableway connection according to the invention is a separate component that can be coupled with cable ducts of known design.
  • the cableway connection according to the invention can be constructed in one piece with the same material or can be composed of several components.
  • the cableway connection can be retrofitted. However, it is preferred when installing the structured cabling for the first time.
  • the cableway connector is provided for connection to a cable track for routing cables from and to the cableway over an upper edge of a sidewall of the cableway.
  • the invention is based on a cross-sectionally U-shaped, upwardly open cable paths, in which a plurality of cables in parallel be led side by side. The invention further assumes that the cables are guided over the upper edge and should extend laterally down the cable path.
  • a protective rail To protect the cable in the upper edge of a protective rail is provided with a curved surface, which is coupled to the upper edge of the cableway.
  • the protective rail should cover the upper edge of the cableway, so that the routed cables no longer come into contact with the upper edge, but only with the curved surface of the protective rail.
  • the protective rail therefore extends on both sides alongside the upper edge or the side wall of the cable path.
  • the invention further provides that at least one limiter is arranged at one end of the protective rail, wherein the limiter projects beyond the curved surface in order to prevent the cables from slipping off the surface. If the cables are fed from one direction only the cable connection, the cables are deflected only from one direction. You could therefore only slip off in one direction from the surface of the guard rail. In this case, a one-sided limiter is sufficient.
  • the invention also takes into account that cables are fed from several sides of the cableway connection. In this case, limiters are provided at both ends of the guard rail.
  • the cableway connection according to the invention also has a profile rail for fastening clamps.
  • the profile rail is in particular a C-profile, to which clamps can be mounted as required in terms of number and shape.
  • the profile rail is arranged at a distance from the protective rail.
  • the rail is connected via at least one strut with the guard rail.
  • the rail is not attached directly to the cableway, but preferably below the cableway, ie at a vertical distance to the protective rail.
  • the rail with the clamps does not cause the deflection of the cables. The deflection takes place in the area of the protective rail. This disconnects the functions of clamping and redirecting.
  • the cables are spared.
  • the cables run perpendicular to the rail or the clamps arranged therein.
  • the clamps are preferably arranged so that the cable after the deflection over the guard rail 5 to 40 cm grade before being held by the clamp. As a result, all cables are fixed uniformly within the clamp.
  • the cableway connection has at least one support, which engages under the mounting position of the cableway connection, the cable path.
  • the support is arranged in a sense on the back of the cableway connection.
  • the support preferably extends from the rail, so that the load of acting on the rail guide cable can be initiated directly into the cableway. This results in no bending moments within the strut.
  • the strut can thus be designed slim.
  • the support is preferably connectable to the cableway, in particular screwed.
  • the support is adjustable in length.
  • the length adjustability makes it possible to adapt the supports to the respective hole pattern of the cable trays and also to the respective existing installation space.
  • the length adjustment of the support can be made continuously, in particular through slots. Even a discrete setting to certain predetermined lengths is possible.
  • the supports are inclined to the underside of the cableway.
  • the distance of the rail to the protective rail can preferably also be adjusted continuously by appropriate slots in the supports.
  • a discrete hole pattern is also possible to keep gridded distances.
  • the profile rail runs parallel to the protective rail.
  • the rail is connected via a connecting element with the at least one strut, wherein the connecting element simultaneously connects the support with the rail.
  • the three components mentioned are bolted together.
  • the at least one limiter is detachably connected to the protective rail and optionally connected to a first end of the protective rail or to a second end of the protective rail.
  • the limiter can be mounted depending on the feed direction of the cable strands.
  • a standardized design provides limiters at both ends of the guardrail.
  • the limiter in an advantageous development of the invention, also has a curved surface on its side facing the cables to be guided.
  • the curved surfaces of the protective rail and / or the at least one limiter are preferably lateral surfaces of an elliptical cylinder or a circular cylinder. In terms of manufacturing technology, circular cylindrical surfaces can be produced easily.
  • the curvature should not be greater than 1/30 [1 / mm] at any point, especially for elliptical cylinders.
  • the curvature is the reciprocal of the radius.
  • the curvature K may accordingly not be greater than 1/30.
  • the curvature K of the protective rail and / or the at least one limiter is less than 1/30 to 1/80 mm.
  • the curvatures of the respective surfaces are identical.
  • the surface of the at least one limiter preferably takes the form of a circular cylinder jacket.
  • the protective rail can be formed as a hollow or full circular cylinder.
  • the protective rail is made of a full circular cylinder. If the diameter of the circular cylinder is 60 mm and at the same time the limiters also have the shape of a half-circle cylinder, from a uniform circular cylinder profile both the respective limiter and the protective rail can be produced.
  • the strand-shaped circular cylinder is to be halved in length. Front fences of the 60 mm diameter limiters allow the limiters to be placed on the upward facing surface of the circular cylinder jacket. The limiters are thus at the ends of the protective rail.
  • a protective rail made of a solid material also makes it possible to form a U-shaped longitudinal groove in the protective rail, which serves for engagement with the upper edge of the side wall of the cableway.
  • the protective rail can thereby be plugged in the longitudinal direction of the upper edge.
  • the longitudinal groove may be so deep that support the walls of the longitudinal groove on the side wall of the cableway.
  • an anti-rotation of the protective rail is provided in the longitudinal direction.
  • the longitudinal groove need not be centrally directed for this purpose on the central longitudinal axis of the guard rail. It can in particular also laterally extend as a secant relative to the circular cross section of the protective rail, of course, without penetrating the protective rail over the entire length.
  • the longitudinal groove can also be used to fasten the strut within the longitudinal groove, in particular to screw with a groove wall.
  • the strut can be embedded in the groove wall.
  • the groove wall or groove cheek can be stepped for this purpose at least in the attachment region of the strut.
  • the at least one strut extends beyond the rail to laterally engage with an existing further cable web, which extends below the first cable web carrying the cable connection support this further cableway.
  • the free end of the strut thus fulfills a dual purpose: On the one hand, there is a great deal of room for fixing the profile rail. On the other hand, depending on the installation situation, an additional support can be dispensed with in that the at least one strut is not only supported on the further cable path, but is connected to this further cable path. A rear support can be omitted. It is even conceivable to use the attachment with the second cableway for simultaneously securing the rail. For this reason, the cableway connection according to the invention in its basic embodiment consists only of the protective rail, at least one limiter, the rail for mounting clamps and the struts, via which the protective rail is connected to the rail.
  • the struts have at least one slot for stepless adjustment of the distance between the guard rail and the rail.
  • This slot can extend to the free end, so that an individual attachment with a second, extending below the first cableway, cableway is possible.
  • the protective rail and / or the at least one limiter preferably consists of a plastic, preferably of POM (polyoxymethylene). This plastic has a high rigidity, a low coefficient of friction and is thermally stable.
  • the cableway connection is provided with two limiters which, together with the protective rail in the installed position, delimit an upwardly open, substantially U-shaped leadthrough area for cables. Due to the rounded limiters and protective rails, the lead-through area is generally adapted to the specifications of the cable manufacturers.
  • the cableway connection according to the invention is flexible, retrofittable, inexpensive and also light. It is structurally simple in construction and constructed by the combination of struts and columns so that hardly bending moments occur, but almost exclusively tensile and compressive forces. As a result, a very lightweight and material-saving design is possible, which does not lead to a load on the cableway or the supporting structures.
