Definitions

  • the invention relates to a data transmission cable and a method for producing a data transmission cable.
  • Such cables are known in the most varied of embodiments in communications technology or in the field of data transmission.
  • the further development of such cables generally relates to the achievement of better electrical parameters, for example wave impedance, damping, inductive and capacitive coating, crosstalk, etc.
  • a good transmission quality is always achieved, inter alia, if these parameters have a constant value at all points of the cable and this Value especially when bending or twisting the cable, e.g. B. in cable manufacture itself or later laying, maintained.
  • DE-AS 1 059 065 discloses a foam-insulated telecommunication cable with a star quad stranding, which essentially has the following elements: at least four stranded single cores, a core covering surrounding the individual cores, a foamed intermediate sheathing arranged on the core braiding and an all-round, non-foamed outer sheath.
  • the core weaving primarily serves to hold the stranding elements together for the further processing steps.
  • the intermediate sheath is primarily intended to protect the stranded single wires against the ingress of moisture.
  • DE-PS 734 148 shows a star quad, the space between the wires of the star quad is filled with rubber.
  • the cores are surrounded by a metallic conductive layer and a rubber jacket.
  • US Pat. No. 2,871,151 proposes to wrap the conductors in each case with an insulating tape with such a high pitch that the winding only covers approximately 60% of the conductor surface. These incompletely insulated cores with partly exposed conductors are embedded in an insulating jacket. It is proposed to provide this sheath made of a material with the same dielectric constant as that of the material used for the conductor wrapping.
  • DE-OS 31 44 743 shows a flexible line with five single wires.
  • a sheath embedding the wires is designed to be compressible in order to allow the compressible material to be pressed together with the embedded wires when subjected to stress and torsion. This embedding is intended to ensure the flexibility of the line with simultaneous particular durability.
  • US Pat. No. 4,835,394 shows a flat cable with many cores running parallel in one plane. This flat cable should conduct small amounts of electrical charge as undisturbed as possible. To avoid displacement of a shield caused by bending relative to the rest of the flat cable, it is proposed to fix the shield on the flat cable by gluing.
  • the invention aims to provide a cable that ensures reliable and as unadulterated data transmission over long distances as possible.
  • a data transmission cable with an outer sheath, at least one shield enclosed by the outer sheath, at least one intermediate sheath surrounded by the shield and at least four stranded single wires forming a star quad, each having a conductor and a wire insulation surrounding the conductor, the intermediate sheath is arranged around the star quad and at least partially fills in notches between surfaces of adjacent individual cores, so that it fixes the geometry of the star quad.
  • the individual wires advantageously have a defined position with respect to one another over the entire length of the cable, which means the data transmission Significantly improved, especially over long distances.
  • the operating capacity of a pair of conductors which transmit an electromagnetic wave is determined, inter alia, by the geometric arrangement of the individual conductors in the cable core.
  • the inductance of the cable depends on the magnetic field outside the individual conductors and is therefore primarily determined by the distance between the individual conductors.
  • Both sizes - capacitance and inductance - have a significant influence on the resistance, crosstalk and attenuation behavior of a cable. According to the invention, these have a defined value over the entire length of the cable. This is ensured in particular by the fact that the position of the individual conductors or individual conductors is the same at all points of the cable.
  • an intermediate jacket surrounding the individual wires is arranged in such a way that the intermediate jacket prevents a relative movement of the individual wires, in particular transverse to the longitudinal axis of the cable.
  • the intermediate sheath primarily serves to protect against the penetration of moisture and mechanical damage to the individual wires.
  • the intermediate sheath also serves to stabilize the relative position of the individual wires. This has a particularly favorable effect on the so-called crosstalk behavior, ie the unwanted transfer of electromagnetic energy from one line or a pair of conductors into the other.
  • the crosstalk in particular between symmetrical lines, is caused, inter alia, by capacitive and inductive couplings which are due to asymmetries in the electrical field and asymmetries in the geometric structure of the cable.
  • the asymmetries in the geometic structure can be minimized according to the invention by fixing the individual wires relative to one another.
  • the crosstalk behavior remains constant over the entire cable length even with external mechanical influences.
  • the intermediate jacket is designed such that it has cavities, i.e. Notches between surfaces of adjacent individual wires, at least partially filled. This ensures that the position of the individual wires to each other, and thus the geometry of the stranding, remains stable even under extreme mechanical loads.
  • the intermediate sheath is arranged in direct contact with the insulation of the inner individual wires - without any remaining hollow space between the intermediate sheath and the wire insulation.
  • the intermediate sheath thus completely fills the cavity (claim 2) and is tightly wrapped around the individual core insulation, so that, in contrast to the known intermediate sheath technology, a type of "embedding" of the symmetrically stranded single cores in the intermediate sheath material is particularly advantageous.
  • the intermediate sheath wraps itself so tightly around the conductor insulation of the individual wires that they remain in the specified stranding position in every situation, for example when the cable is laid. Emphasis should be placed on the intermediate sheath embedding, which is particularly advantageous in terms of production technology, in a cable consisting of several stranding elements.
  • the intermediate sheath consists of a thermoplastic, in particular polypropylene and / or polyethylene (claim 3). This creates an intermediate jacket that can be processed particularly easily.
  • the two materials mentioned above meet the requirements placed on the required stability of the embedding in a special way.
  • a cable must be easy to handle, especially when it is installed on site.
  • the intermediate sheath material of the invention is therefore particularly advantageously designed to be breakable in such a way that the intermediate sheath can be removed from the cable without a cutting tool.
  • the intermediate sheath can be removed, for example, simply by breaking off the material at the desired location. This makes the cable easier and easier to handle and process. This results in a noticeable simplification and shortening of the work required for installation.
  • the parameters of the intermediate sheath material are advantageously chosen such that the intermediate sheath has different mechanical stabilization requirements depending on the area of application of the embedded single wires.
  • the cable according to the invention can be dimensioned in a user-specific manner by appropriate selection of the flexibility and specification of the foamed intermediate sheath.
  • the banding consists, for example, of several layers of high-quality plastic film.
  • the intermediate sheath according to the invention therefore particularly advantageously embeds the individual wires completely free of stress (claim 5), d. H. the intermediate sheath does not exert any tensile forces, neither in the longitudinal nor in the transverse direction of the cable, so that the stranding of the individual wires remains defined at all times.
  • the insulation of the single wires can be considered together with the intermediate sheath as a uniform insulation parameter, the material data of which are included as a defined quantity in the model calculation of the line theory.
  • the electrical processes during data transmission after elimination of undetermined factors can be recorded much better.
  • the defined conductor geometry also proves to be particularly favorable due to the inventive stabilization of the individual wires.
  • the impedance is approximately between 85 ⁇ and 150 ⁇ (claim 6).
  • the advantages of the cable concept according to the invention have a particularly favorable effect. If, for example, the four individual wires of a stervier do not lie in the corners of a square - viewed in cross section - but if the stervier is deformed into a rhomboid, the capacitive crosstalk becomes particularly large. This can be successfully avoided by the geometric stabilization according to the invention.
  • the inductive crosstalk between the two main lines of a veterinarian is minimal if they are ideally perpendicular to each other. According to the invention, this arrangement can be achieved over the entire length of the cable even with external mechanical action.
  • the diameter of the individual individual wires is particularly advantageously approximately 1 mm or less and the diameter of the entire cable is approximately 5 mm (claim 7). Since the advantages of the intermediate sheath, in particular the easily removable intermediate sheath, come into play particularly in the case of cables with a small diameter, a new type of cable with a small diameter results, which can be used, for example, with so-called RJ45 plugs. suitable is.
  • the data transmission cable constructed in this way enables the use of approximately two to four times smaller plugs and is therefore particularly suitable for device connections with a high integration or packaging density. The use of smaller plugs in turn opens up space for new developments and a higher integration density in the patch panel area.
  • the shield has an aluminum foil, a wire mesh and possibly one between the aluminum foil and the wire mesh extending in the longitudinal direction of the cable drain wire (claim 8).
  • the cable designed in this way is particularly practical to handle, simple to manufacture and has all the advantages of a single wire or conductor position stabilized in any situation.
  • the individual conductors consist of flexible seven-fold or multiple strands, in particular of bare, tinned, silver-plated or galvanized copper strands (claim 9). Contrary to previous estimates, surprisingly good values in terms of near and cross-talk attenuation can be achieved with such a cable, in particular data transmission cables with a small diameter. In this way, the quadruple coupling and the crosstalk effects between the different single wires can be controlled well.
  • the object of the invention is also achieved by a method for producing a data transmission cable, wherein at least four individual wires, each having a conductor and a wire insulation surrounding the conductor, are stranded into a star quad, an intermediate sheath is arranged around the individual wires, which notches between surfaces adjoining one another Fills individual wires at least partially, so that it fixes the geometry of the star quad, the intermediate sheath is surrounded by at least one shield and the shield is enclosed by an outer sheath (Claim 10).
  • the intermediate sheath is preferably applied directly to the stranded individual cores, in particular sprayed on (claim 11). This results in a tight-fitting, stabilizing, insulating intermediate jacket embedding with the advantages described above.
  • the requirements placed on the function of the intermediate jacket which protects, stabilizes and isolates in particular from mechanical damage and moisture, are particularly met.
  • the foaming parameters amount of blowing agent, germs, ...) and / or chemical additives (solvents, plasticizers, ...) to the starting material, the physical and chemical properties, such as flexibility, dielectric constant, softening point, especially with regard to the the type of embedding designed intermediate sheath can be controlled particularly advantageously.
  • the diameter or the wall thickness of the intermediate jacket is set by means of a diaphragm with an adjustable opening attached to the outlet of an application device (claim 12).
  • the portion of the intermediate sheath that is larger than the size of the aperture is stripped off after the injection process by pulling the cable through the opening.
  • a data transmission cable 1 consists of four individual wires 2A, 2B, 3A, 3B, the diagonally opposite individual wires 2A and 2B as well as 3A and 3B forming an associated pair of wires 2, 3 for transmitting an electromagnetic wave.
  • the single wires can have such a small diameter - e.g. 1 mm - that the data transmission cable 1 is particularly suitable for small plugs.
  • Such plugs typically have external dimensions of approximately 10 mm ⁇ 5 mm, the distance between the individual plug contacts being approximately 1 mm.
  • the individual single wires are adapted to this distance.
  • the diameter of the cable core is on the order of approximately 2 mm.
