Definitions

  • the invention relates to a set for producing an electrical installation comprising a continuous flat cable with data lines and at least one connection device for stripping-free Anzapfffy réelle the data lines.
  • the data lines are surrounded by a shield which, apart from end seams of the shielding film, has seams or overlaps only on the narrow sides of the flat cable, so that the flat sides to be tapped are free from seams / overlaps.
  • connection devices in which a connecting flat cable with a plurality of in-plane data conductors without separation of the wires and without removal of wire and cable insulation and shielding can be tapped with a connection device, are known from the prior art.
  • An early related patent document from the Applicant's house is the DE 4402837 C2 .
  • the hybrid flat cable with power and data lines described herein can be tapped without insulation by means of connecting devices.
  • the connecting device is placed on a flat side of the flat cable and has cutting as a tapping contact, which slit the current and data cores to be tapped in the longitudinal direction and thus brings about a contact. As part of the tapping process of the data lines and their shield is pierced.
  • shields of non-twisted data conductors are described, for example, in the European patent specification EP 0 214 276 B1 and the US patent US 5,900,588 described.
  • the main focus of the proposed variants of the shield is to ensure good electrical data transmission properties and a robustness against external mechanical effects.
  • shields are wrapped in the form of laminated metal foils around the data conductors, with one end of the laminated film being folded back for complete shielding, so that the metal sides of the foil lie on top of each other, are electrically connected to each other, thus forming a complete Faraday cage.
  • the set according to the invention for producing an electrical installation has at least one flat cable and at least one connecting device complementary to the flat cable with tapping contacts for the stripping-free tapping of the flat cable.
  • the flat cable comprises at least one pair of data conductors which run untwisted in parallel.
  • the data conductors are surrounded by a shield which, apart from possibly existing end seams at the shielding end, has seams only on the narrow sides of the flat cable, so that the flat sides to be penetrated by the tapping contacts are free of any shielding seams.
  • the tap contacts are insulated from the shield, so that the data conductors can be tapped by penetrating the shield through the tap contacts, without there being a penetration in the region of a shielding seam.
  • an electrical installation is proposed in which the flat cable is tapped with the connection device, that is to say that the shield has been pierced by the tapping contacts in the regions of the flat sides which are free of the shielding seam.
  • the invention thus aims at a trouble-free penetration of the shield by the tap contacts and thus on a secure tap shielded data conductor.
  • the set according to the invention for producing an electrical installation comprises a flat cable with shielded data conductors and at least one connection device suitable for the flat cable for a stripping-free tap connection of the data conductors to basically any longitudinal positions of the flat cable.
  • the "fitting" of the connection device to the flat cable on the one hand affects the outer shape of both parts of the sentence. This is such that their geometry is coordinated so that the connection device can be placed on the flat cable for the purpose of tapping. Preferably, it is ensured that there are only certain possibilities of this placement in order to allow a correct tapping.
  • the "fit” is also expressed in the position of the data conductor and the tapping contacts provided for tapping on the connection device.
  • the longitudinal position of the data conductors in the flat cable is firmly defined in that they run as parallel as possible and untwisted, for example, in a surrounding embedding, at a fixed distance from one another. Due to this defined longitudinal position, a successful stripping-free tapping of the conductors is made possible.
  • the tapping contacts of the terminal device correspond to the number of data conductors and are aligned with their known position in the cable. Thus, it is ensured that the data conductors are "hit" after the attachment of the connection device on the flat cable with the tap contacts and the tapping is successful.
  • the electrical data transmission in a data conductor is sensitive to external electromagnetic interference (exception are the known optical waveguides, which are not tap taping by Anzapf marchierung but, for example, be connected by plug or splice at the cable end). It therefore makes sense to protect data conductors against such interference.
  • a Shielding may even be necessary to ensure a functioning data transfer at all. This is the case, for example, with cables which, in addition to data lines, also accommodate a power supply (so-called hybrid cables).
  • the current conductors running in the immediate vicinity of the data lines cause an electromagnetic field which causes interference interference for signal transmission in the adjacent data conductors. Even a pure data cable without a power supply component may experience interference if it is used near a foreign (not your own) power cable or other source of interference.
  • Such untwisted data conductors in flat cables which are provided with a shield designed closer, are already basically from the European patent EP 0 214 276 B1 and the US patent US 5,900,588 known.
  • the type of shielding the data conductor is there, however, priority from aspects of data transmission (eg, the best possible shielding of interference, low attenuation, little bit offset, etc.) or any mechanical effects (eg good data transmission even when bending the cable or external pressure, eg pedaling on a laid under a carpet flat cable) optimized.
  • the present invention focuses on the particular configuration of the data conductor shield in the flat cable, taking into account the stripping-free tap.
  • the data conductors should in principle be able to be tapped without stripping at any longitudinal position. Accordingly, in the present case, the shielding is aligned with such a tap, ie puncturing or cutting through the conductor shield at any desired longitudinal positions of the flat cable.
  • the piercing of the shield takes place in the context of the tapping operation on one of the two flat sides of the flat cable (see DE 4402837 C2 ). Because the conductors to be tapped run in the flat cable harness substantially in the flat plane next to each other, so that ideally tapped approximately vertically to this plane (the penetration of tapping contacts not necessarily be linear, but as in the type of DE 102007041814 A1 in the cable longitudinal direction movable tapping contacts, for example, elliptical nature may be). In these known electrical Installation systems do not provide for tapping-piercing data conductor shielding. Rather, as already mentioned above, the shielding is designed solely for the purpose of the best possible data transmission, or else its detailed design simply left open.
  • seams are understood to mean not only joint-like or plane abutting ends of shielding foils but, for example, also all types of overlaps, including those with simple or deviating from the usual usage repeatedly folded back ends, as they are approximately from the US 5,367,123 or US 5,900,588 are known.
  • seams or “seams” are used herein as generic terms of all types of connections of shielding edges.). It has been recognized that such seams may present problems in the area of tap areas where the shield is pierced.
  • the shield according to the invention is designed so that it has seams only on the narrow sides of the flat cable, because in these areas naturally no tapping occurs.
  • the intended for the tap flat sides are basically free of shielding seams. Exceptions are any seams at the end of the shielding film.
  • the pieces of film are, for example, rectangular with a long longitudinal and a short, matched to the cable circumference transverse edge. They are beaten with the short transverse side around the data conductor, so that their long side approximately coincides with the cable longitudinal direction.
  • the shielding pieces are only of limited length (for example, 300m) so that the length of the cable may well exceed that of the shielding foil.
  • the flat side of the flat cable may have such end seams at the end of the shield (i.e., at the transverse or face side of the foil pieces), there are no other seams not caused by the material end of the shield.
  • This type of shielding is achieved, for example, by virtue of the fact that the at least one pair of data conductors will only fold over once with the shielding material in such a way that their longitudinal edges are guided back towards one another on just one of the two narrow sides and only there is a shielding seam produced (more details on the type of production the flat cable follows below).
  • the present shield has, for example, only one shielding seam on one of the two narrow sides of the cable.
  • a separate shield is provided, for example, in accordance with the principles of paired, symmetrical signal transmission for each data conductor pair, which in turn only have seams only on the narrow sides of the flat cable.
  • a shield surrounding all data conductor pairs can be provided, which also follows the sketched structure with seams along the flat cable narrow sides.
  • the tap contacts of the connection device are insulated against the shielding to be pierced (partially).
  • the data conductors can be tapped with the connecting device by the tapping contacts pierce the shield in the seamless area of the flat side of the flat cable and establish electrical contact with the data conductors.
  • the flat cable is produced by first encapsulating the at least one pair of data conductors by means of an extrusion process in a first operation, so that they are surrounded by a data conductor embedding.
  • a data conductor embedding can for example be made of foamed dielectric, which allows a low dielectric constant and a stable signal transmission.
  • the next step concerns the assembly of the shield.
  • the shielding foil is wrapped around the data conductor embedding in such a way that a substantially longitudinally extending shielding seam is formed on one of its two narrow sides.
  • two pieces of film can be placed on both flat sides of the leitereinbettung whose longitudinal edges then meet each other on the narrow sides, so that on each of the two narrow sides a shielding seam is formed.
  • the detailed design of the shielding seams is irrelevant.
  • the ends may be laid flat against each other and adhered to the data conductor embedding, or they may be overlapped, with or without struck back on each other and glued or welded together. It can also be glued to the entire shielding film on the leitereinbettung.
  • the film pieces each have a certain length, for example, 300 meters. If the flat cable is longer than the length of the film pieces, the first piece of film wrapped around the data conductor embedding closes or, if appropriate, several further pieces of film. These are struck around the data conductor embedding analogously to the first piece, so that in turn the lateral shielding seam is formed on the narrow side of the data conductor embedding (or possibly seams on both narrow sides). By this juxtaposition also create end seams as a compound of several pieces of film. These end seams each run around the data conductor embedding around, are also on the flat sides in the areas of potential tap. If the cable length is equal to the length of a shielding film piece, or if the cable is even shorter, then the problem of the end seams does not arise. The flat sides are then completely free of any seams.
  • the data conductor embedding thus shielded is still surrounded by a protective jacket. This can also be done by an extrusion process.
  • the protective jacket is used to isolate the shielding to the outside and the protection against harmful external influences, for example. Mechanical, chemical o.a. Art.
  • a film of an aluminum alloy is used as the material for the shielding.
  • a wire mesh can be used. The thickness and the specific nature of the alloy or the wire mesh depend on the desired shielding strength.
  • the film or the wire mesh are laminated to increase the tear resistance with a plastic film.
  • the aluminum side of the shielding foil lies on the side facing the data-conductor embedding, while the plastic-coated side is oriented outwards.
  • the shield is formed on a specific length of the flat cable from a single piece of film. Accordingly, there is only one shielding seam on one of the two narrow sides of the flat cable and no end seams on this longitudinal section. By way of example, this could be a longitudinal section of 300 meters.
  • the shield is formed of a plurality of juxtaposed pieces of film, which are connected to each other by means of end seams for the purpose of continuous shielding. For example, over a length of about 900 meters three pieces of film could be strung together a 300 meters may be, which overlap in the region of the two end seams between the first and second and the second and third pieces of film by a few millimeters or centimeters.
  • the entire shield of the flat cable is in one piece, so that it has only one shielding seam on a narrow side and no end seams.
  • the flat cable is designed as a hybrid cable.
  • it has current conductors.
  • the latter run like the data conductors untwisted and substantially parallel to each other in the flat plane of the flat cable, so that they can be tapped by means of the connecting device.
  • the conductors can be low, medium or heavy current conductors.
  • the surrounding with the shield data conductor embedding is embedded together with the individual conductors in a common jacket, which determines their position in the flat cable and gives it its outer shape.
  • the connection device in turn is adapted to the flat cable. It also has tapping contacts for the current conductors.
  • the data conductor shielding is of particular importance, because with the current conductors one of the possible sources of electromagnetic interference runs in the immediate vicinity of the data conductors.
  • the hybrid flat cable it has three three-phase conductors, a protective conductor and a neutral conductor and a pair of data conductors.
  • the outer geometry of both phrases continue to match each other so that the connection device can be placed without confusion on the flat cable.
  • This is for example in the aforementioned flat cables with three three-phase conductors of importance if only one of the three-phase three phases is to be tapped for installation.
  • the outer geometry of the flat cable (so-called coding) and the complementary outer shape of the connection device (for example in the form of a flat cable receiver) are, for example, asymmetrically designed such that the connection device for tapping the flat cable only in a defined orientation, but can not be placed in a rotated by 180 ° orientation. Thus, an accidental incorrect placement of the connection device is prevented and ensures proper tapping.
  • an electrical installation device In the installed, ie tapped state of the inventive set forms an electrical installation device.
  • a typical installation procedure might look like this:
  • the flat cable is laid to make the installation in accordance with the particular space conditions.
  • cable routes such as the establishment of line routes, shafts, channels or other cavities.
  • This also includes, depending on the type of installation, the assembly of distribution and control boxes and / or cans.
  • the at least one connection device can be placed at a desired location of the continuous flat cable.
  • tapping process is carried out, depending on the specific design of the connecting device, for example by screwing in the tapping contacts in the form of contact screws or a force acting (directly or indirectly) on contacts in the form of tapping mandrels or -.
  • the tap contacts of the connection device penetrate the outer protective sheath, the shielding in the region of the selected seamless flat side of the flat cable, the data conductor embedding and the core insulation until they contact the data conductor strands.
