Definitions

  • the invention relates to a cable, in particular a data cable, and a method for producing such a cable.
  • Cables are used for data transmission which are designed as data cables and which typically have a number of data lines which are combined in a common cable sheath.
  • shielded core pairs are frequently used as data lines, in which two cores in particular run parallel to one another or alternatively are twisted together.
  • Each core consists of the actual conductor, for example a solid conductor wire or a stranded conductor, which is surrounded by insulation.
  • the wire pair of a respective data line is surrounded by (pair) shielding and a data cable typically has a large number of wire pairs shielded in this way. These wire pairs are also often surrounded by a shared outer shield and a shared cable sheath.
  • Such data cables are used for high-speed data transmission and are designed for data rates greater than 5 Gbit/s, in particular for use at frequencies from 14 GHz.
  • the outer shield is primarily important for EMC and EMI properties, it typically does not transport any signals.
  • the respective shielding of an individual data line determines the symmetry and the transmission properties of the respective wire pair.
  • the shielding of a respective data line is designed, for example, as a longitudinally folded foil shielding.
  • a shielding film is used, which is folded around the wire pair running in a longitudinal direction of the cable, the two ends being overlapped in an overlapping area which runs in the longitudinal direction.
  • the shielding foil used for the shielding is typically a multilayer foil made of at least one conductive layer, ie a conductive layer, and an insulating layer, ie an insulating layer.
  • An aluminum layer is usually used as the conductive layer and a PET film is used as the insulating layer.
  • the PET film is designed, for example, as a carrier on which a metallic coating is applied to form the conductive layer, so that the overall shielding film is a so-called laminated film.
  • the aim is generally to increase the transmission capacity, i.e. the amount of information per time.
  • the required transmission rates and the frequency range in which such data cables are operated are increasing more and more.
  • WO 2015/075208 A1 shows a data line with a multi-layer, longitudinally folded shielding foil, which has a middle insulating layer on which a conductive layer is applied on both sides.
  • the two conductive layers are conductively connected to one another on the face side, for example by the application of a conductive strip.
  • the cable is designed in particular as a data cable, in particular for high-speed data transmission for data rates greater than 5 Gbit/s and/or for use at frequencies from 14 GHz.
  • the cable has a cable core which is surrounded by a shielding film which has an insulating layer on which a conductive layer is applied on both sides, namely on an upper side and on a lower side.
  • the two conductive layers are electrically conductively connected through the insulating layer.
  • An advantage of the invention consists in particular in the fact that resonance effects are effectively avoided by connecting the two conductive layers to one another.
  • the formation of a series resonance is effectively avoided by the shielding film.
  • Such a series resonance occurs with conventional shielding foils because the two conductive layers of the shielding foil do not touch, i.e. are not connected to each other and therefore no continuous shielding is implemented. This also applies in the case of a shielding film with only one conductive layer, which is then not in contact with itself when surrounding the cable core.
  • the special shielding film in the present case forms a closed shield along which an induced current can spread essentially arbitrarily and particularly cheaply and in particular without resistance.
  • a pure metal foil as the shielding film in order to implement closed shielding.
  • the shielding foil then only has a conductive layer and no insulating layer.
  • the conductive layer is optimally contacted with itself both when spinning and when longitudinally folding and forms a closed shielding.
  • a pure metal foil is mechanically not very robust and there is a risk of tearing and general damage, especially during manufacture of the cable.
  • a shielding film with an insulating layer is significantly more stable and also easier to produce, which then gives the shielding film greater overall mechanical stability.
  • a further advantage of the invention consists in particular in the fact that it combines the advantages of a pure metal foil and a shielding film with an insulating layer, since a shielding film that is particularly stable from a mechanical point of view and, above all, particularly tear-resistant, is used. which at the same time also leads to improved electrical properties, namely improved shielding, as described above.
  • the cable core has at least one core, but usually multiple cores.
  • the cable core is preferably a wire pair with two wires which, together with the shielding film, form a shielded line, in particular a data line of the cable.
  • the cores of the cable are either routed parallel to one another or twisted together.
  • the cable itself has a plurality of such separately shielded lines.
  • the shielding foil is preferably used to form shielding of a line, but in principle the underlying concept can also be used advantageously for external shielding of the entire cable. In a suitable alternative, the shielding foil is therefore arranged around several lines of the cable and forms an outer shield. In other words: the shielding foil is alternatively an overall shielding of the cable and surrounds all the cores and/or lines of the cable.
  • the shielding formed by the shielding film consists preferably only of one shielding film and otherwise has no further shielding films.
  • the cable core, in particular the line is only surrounded by a shielding film.
  • a multi-layer structure with several foils is therefore dispensed with here.
  • the shielding is structurally particularly simple and space-saving.
  • Such a configuration is particularly advantageous when shielding individual cores or core pairs for the purpose of forming lines.
  • a braided shield is optionally arranged in addition to the shielding foil.
  • the insulating layer generally consists of an insulating material, eg a plastic, preferably PET.
  • the conductive layers each generally consist of a conductive material, eg a metal, preferably aluminium.
  • the conductive layers extend flat on the top and bottom of the insulating layer, so that in the finished cable one conductive layer, namely the one on the bottom, is on the inside and the other conductive layer is on the outside.
  • the conductive layers are glued to the insulating layer, for example.
  • the conductive layers are, in particular, designed to be essentially continuous, ie they essentially cover the insulating layer completely. In this context, “substantially completely” is understood to mean in particular that the conductive layer covers at least 90%, preferably at least 99%, of the insulating layer, particularly preferably the entire insulating layer.
  • the two conductive layers are in direct contact with one another through the insulating layer.
  • This configuration is particularly simple, since additional components or structures for connecting the two conductive layers are dispensed with. Rather, the conductive layers are in direct, i.e. immediate contact with one another, i.e. they touch one another.
  • the insulating layer is left out or displaced in certain areas, so that the two conductive layers are connected through the insulating layer. In this way, a direct contact of the two conductive layers is formed. In particular, the connection of the two conductive layers does not require any further material.
  • the two conductive layers are connected to one another by means of a large number of contact points.
  • the conductive layers are furthermore advantageously essentially flat and in particular also continuous, ie essentially uninterrupted.
  • the insulating layer is perforated or interrupted at the contact points.
  • An electrical connection between the two conductive layers is realized locally by a respective contact point.
  • the two conductive layers are still spaced apart and insulated from one another by the insulating layer. Due to the large number of contact points, which are arranged distributed over the shielding foil, a uniform electrical connection is then realized, which enables a large number of current paths along the shielding, as a result of which resonance effects are avoided in a particularly effective manner.
  • the contact points preferably make up less than 1 to 10% of the total area of the shielding film, so that the shielding film, despite the contact points, is still essentially a multilayer film with conductive layers spaced apart from one another by an insulating layer.
  • the shielding foil is advantageously applied in the finished cable in such a way that the coated cable core is optically covered. This means that the film overlaps with itself in overlapping areas in such a way that as few as possible, preferably no, contact points lie on top of one another. As a result, optically dense shielding is then formed, in which the cable core is covered at every point by at least one conductive layer.
  • a single contact point preferably has a dimension in the range between 0.05 and 0.5 mm, i.e. is approximately as wide and/or long as the overall thickness of the shielding foil. In principle, however, other dimensions are also conceivable and suitable.
  • the contact points are therefore not large-area structures that take up a significant area of the shielding film, but rather structures with particularly small dimensions that do not significantly affect the external appearance of the shielding film as such with essentially continuous conductive layers. Nevertheless, the contact points are usually visible to the naked eye.
  • the contact points are expediently arranged in a pattern and at regular intervals from one another. This achieves a particularly homogeneous and controlled contact, ie the electrical properties of the shielding are particularly uniform along the cable.
  • the electrical properties and in particular the shielding and resonance properties of the shielding and thus of the cable as a whole can be set via the precise design of the pattern and the distances between the contact points. Therefore, the pattern is suitably chosen such that the transmission properties of the cable are optimized with respect to the intended application of the cable.
  • the shielding film surrounds a wire pair in particular
  • the pattern is then designed in such a way that the greatest possible common-mode rejection results.
  • the distance between the contact points to one another is expediently dependent on the intended Transmission frequency set at which the cable is to be operated.
  • the contact points are arranged in rows and columns in a grid-like manner, with the rows being perpendicular to the columns, giving the visual impression that the contact points are arranged on corners of imaginary squares, i.e. on a rectangular grid.
  • every other row is offset by half the distance between two adjacent pads, giving the visual impression that the pads are arranged on corners of imaginary diamonds, i.e. in an oblique grid.
  • the distance between two contact points i.e. in particular the distance between a contact point and its nearest neighbor, is preferably between 0.1 and 4 mm.
  • the resulting cable is then particularly suitable as a data cable and for data transmission at data rates greater than 5 Gbit/s or at frequencies above 14 GHz.
  • the conductive layers are pressed against one another at the contact points, i.e., in particular, are connected to one another in a form-fitting manner.
  • the shielding foil is prepared in such a way that the insulating layer is interrupted, displaced or destroyed locally, namely at the contact points, and as a result is broken through, so that the two conductive layers are connected to one another.
  • a form fit is realized in such a way that at least one of the conductive layers, preferably both conductive layers, engages or engage in the interrupted insulating layer.
  • the shielding film is perforated to form the contact points.
  • a perforation is particularly easy to carry out, so that the cable is particularly easy to manufacture.
  • the perforation presses the two conductive layers against one another and breaks through in such a way that a connection is made through the insulating layer through.
  • the shielding foil and, above all, the insulating layer are destroyed locally and the material of at least one of the conductive layers is introduced into a recess formed in this way in the insulating layer.
  • the conductive layers are connected to one another by the material of the at least one conductive layer being pressed to a certain extent into the insulating layer.
  • the shielding foil thus has a perforation which forms the contact points.
  • it is, for example, punched or pressed at least locally in the area of the contact points to be formed.
  • a perforating unit known per se is particularly suitable for perforating the screen film.
  • the specific form and geometry of the connection may differ greatly in detail at different contact points, i.e. in particular on a microscopic scale. This is particularly due to the manufacturing process for the contact points. For example, during perforation, the shielding film is destroyed locally in a way that cannot be completely reproduced. The contact points produced then sometimes have a different connection quality.
  • the large number of contact points advantageously ensures that, on average, there is sufficient electrical contact between the two conductive layers.
  • the contact points are in the form of points or slots and are therefore particularly small in size and correspondingly space-saving.
  • the shielding foil is only modified locally by the contact points, while the majority of the shielding foil, i.e. in particular at least 90%, preferably at least 99% of the total area, remains unaffected and is correspondingly intact or undamaged, i.e. with an intact insulating layer which separates the conductive layers and isolated from each other.
  • punctiform contact points are produced, for example by means of a needle, and slit-shaped contact points, for example by means of a knife.
  • a laser method is also suitable for connecting the conductive layers and for forming the contact points by means of the perforation.
  • the shielding film is provided with contact points over its entire surface.
  • the contact points may form structural weak points in the shielding film.
  • the shielding foil therefore has a free area, in particular a side edge, in which the two conductive layers are electrically separated from one another, in particular continuously by the insulating layer.
  • the shielding foil is free of contact points, i.e. the two conductive layers are not connected to each other in the free area.
  • the insulating layer is not broken.
  • the free area expediently extends along the entire shielding foil.
  • the free area has a dimension that is significantly larger than the distance between the contact points.
  • the free area is arranged at the edge of the shielding film.
  • the free area is not arranged at the edge, but runs e.g. in the middle.
  • the shielding film has a number of free areas.
  • a longitudinal fold in which the shielding film is placed around the cable core in such a way that the lateral edges of the shielding film run in the longitudinal direction of the cable.
  • a braiding also known as banding, in which the shielding film is spun or wrapped around the cable core in a helix-like manner. Both variants can basically be executed with an overlap or butt joint.
  • the additional foil due to the additional foil, the cable is less flexible, more complex to manufacture and the material of the foil may have an unfavorable effect on the electrical properties of the cable.
  • the commonly used polyester is poorly suited for high-frequency applications, ie in particular data transmission.
  • a separate shaping device is required in each case for applying the shielding film, so that this also results in high production costs.
  • the shielding film is preferably spun around the cable core.
  • a wrapping is unsuitable for data transmission cables from a certain frequency due to the resonance effects generated by the wrapping. Due to the interconnected conductive layers, however, this effect is reduced to such an extent or even completely avoided that a braiding for a corresponding cable is sensibly possible, in particular for a cable for data transmission with more than 5 Gbit/s or at frequencies greater than 14 GHz. In the configuration with a spun shielding film, this may also be lower overall than with a longitudinal fold, and the shielding is therefore thinner overall.
  • the spun on shielding foil is still more flexible.
  • the asymmetry due to the longitudinal edge in the longitudinal fold is avoided in principle, so that in particular an additional film as a substructure is dispensed with.
  • the structure of the shielding is therefore particularly simple.
  • a spinning unit used for core spinning can be used particularly flexibly.
  • a perforating unit for online connection of the two conductive layers can also be easily integrated into the spinning unit.
  • the shielding foil When spinning, the shielding foil is typically arranged in several consecutive windings around the cable core.
  • the windings are either designed to butt or overlap in an overlapping area.
  • the cable core comprises a number of cores, i.e. has a number of cores which are directly surrounded by the shielding film.
  • the shielding film is in contact with the cores and the inward-facing conductive layer touches the core sheath or sheaths. There is therefore no need for an additional foil between the wires and the shielding foil.
  • the cable core of the cable is a wire pair, which is then formed as a shielded line and in particular as a data line by means of the shielding film.
  • the cable then includes one or more such lines.
  • the cable core has an inner conductor for a coaxial cable, with the inner conductor being surrounded by a dielectric, which in turn is surrounded by the shielding film.
  • the cable core thus consists of the inner conductor and the dielectric.
  • the shielding foil then forms an outer conductor of the coaxial cable.
  • a cable core is surrounded by a shielding film on which a conductive layer is applied on both sides, namely on an upper side and on a lower side, the two conductive layers passing through the insulating layer are electrically connected.
  • the conductive layers are bonded together during manufacture of the cable.
  • the two conductive layers are connected to one another by perforating the shielding film.
  • a corresponding perforation is produced by means of a perforating unit, to which the shielding film is fed.
  • a perforating unit can be integrated particularly easily into a spinning unit for covering or banding. Therefore, in an advantageous embodiment, the shielding film is perforated and the cable core is braided with the shielding film.
  • Such a method is particularly flexible, especially with regard to different cable structures, geometries and dimensions.
  • a configuration in which the conductive layers are connected to one another immediately before the cable core is surrounded is particularly preferred.
  • a simple shielding film with non-connected conductive layers is thus initially fed to the method as a semi-finished product, preferably a conventional double-laminated film. This is then prepared in the following by first connecting the conductive layers to one another. Directly after connecting the conductive layers, e.g. by means of perforation, the shielding film is then spun onto the cable core. In other words: the cable core is surrounded in a common process step with the connection of the conductive layers. In an advantageous variant, the shielding film is subsequently perforated, i.e. after the cable core has been encased.
  • a cable 2 is shown schematically in cross section perpendicular to its longitudinal direction L.
  • the cable 2 is designed here as a data cable and has two wires 6 as a cable core 4 , which form a wire pair 8 . This is surrounded by a shielding film 10, so overall by the wire pair 8 and the shielding film 10 a shielded line 12, here data line, is formed.
  • the cable 2 has a plurality of such lines 12 .
  • the cable 2 also has an outer sheath 14 which surrounds the cores 6 .
  • an adhesive film is spun on as an alternative or in addition to the outer casing 14 .
  • the representation in 1 is only schematic and does not necessarily depict the individual components of the cable 2 in the correct proportion to one another.
  • the shielding film 10 has a thickness D in the range of approximately 0.1 to 0.5 mm.
  • the diameter of an individual core 6, on the other hand, is between 0.5 and 3 mm, for example.
  • the cable 2 is shown in a cross-sectional view along the longitudinal direction L.
  • the shielding film 10 is spun on in the exemplary embodiment shown.
  • Such a wrapping is generally preferred, but alternatively, instead of wrapping, a longitudinal fold of the shielding film 10 around the cores 6 is also conceivable, with a fold edge then running in the longitudinal direction L.
  • the spun-on shielding film 10 is guided around the cable core 4 in a helical manner and is arranged in a plurality of successive windings which overlap in a correspondingly helical overlapping area 16 .
  • the shielding film 10 is wound butt-to-butt.
  • the shielding foil 10 forms a shield for the line 12 and thus decisively determines the transmission properties of the line 12 and thus of the cable 2 as a whole.
  • the shielding film 10 is specially designed to avoid unwanted resonance effects and in particular a series resonance.
  • the special design is particularly evident in 3 recognizable, which shows a part of the shielding film 10 in a perspective view.
  • the shielding film 10 is a multilayer film with an insulating layer 18 on which a conductive layer 20, 22 is applied on both sides, namely on a top side O and on a bottom side U, namely an upper conductive layer 20, which in the finished Cable 2 faces outwards, and a lower conductive layer 22, which faces inwards in the finished cable 2.
  • the insulating layer 18 is thus arranged between the two conductive layers 20, 22.
  • the conductive layers 20, 22 are made of a conductive material, such as aluminum, and the insulating layer 18 is made of an insulating material, such as PET.
  • the shielding film 10 is a double-laminated film in which the conductive layers 20, 22 are adhesively bonded to one side of the insulating layer 18 in each case.
  • the two conductive layers 20, 22 are not connected to one another, ie not connected to one another in an electrically conductive manner, which usually results in unfavorable resonance effects in the finished cable 2, particularly when operating at high frequencies in the range above 14 GHz.
  • This is prevented in the case of the shielding film 10 shown here in that the two conductive layers 20, 22 are connected to one another, namely through the insulating layer 18.
  • the connection leads to electrical contacting of the conductive layers 20, 22 with one another, so that both are at the same electrical potential and a current can spread largely unhindered on both sides of the shielding film 10, even in the spun-on arrangement as in FIG 2 shown.
  • the conductive layers 20, 22 are connected to one another by a large number of contact points 24.
  • the specific design of the contact points 24 does not necessarily correspond to the only highly schematic representation and 3 , but may actually deviate significantly from it. It is essential that the insulating layer 18 is perforated, interrupted or displaced at the contact points 24 and thereby recesses are formed in it, into which material of the conductive layers 20, 22 penetrates and in this way connects the two conductive layers 20, 22 to one another.
  • the conductive layers 20, 22 are connected in that the shielding film 10 is perforated.
  • the shielding film 10 shown is perforated, in this case in the form of points, so that the contact points 24 are each in the form of points.
  • the insulating layer 18 is broken and the material of the upper conductive layer 20 penetrates through the insulating layer 18 and touches the lower conductive layer 22.
  • the contact points 24 more Holes are formed in the shielding film 10; alternatively, other geometries are also suitable, for example slots, i.e. slot-shaped contact points 24.
  • the contact points form 24 in 3 a pattern in which the pads 24 are equally spaced apart from each other by distances A1, A2.
  • Two suitable patterns are in the 4 and 5 shown schematically.
  • the contact points 24 are arranged in rows and columns in a grid-like manner, the rows being perpendicular to the columns. This gives the visual impression that the contact points 24 are arranged on the corners of imaginary squares Q, ie on a rectangular grid.
  • every other row is offset by half the distance A1 between two adjacent pads 24. This gives the visual impression that the contact points 24 are arranged on the corners of imaginary rhombuses R, ie in an oblique grid.
  • the contact points 24 also connect the two conductive layers 20 , 22 to one another, distributed uniformly over the entire surface of the shielding film 10 .
  • An exception to this is a free area 26, which is also a side edge of the shielding film 10 here. No contact points 24 are arranged on this free area 26 . Since these may form weak points in the shielding film 10, the tear resistance of the shielding film 10 is improved by the free area 26.
  • 6 12 shows a highly schematized method for producing the cable 2.
  • the cable core 4 and the shielding film 10 are fed to a spinning unit 28, by means of which the cable core 4 is spun or wrapped with the shielding film 10.
  • a spinning unit 28 is particularly flexible with regard to the specific design, dimensioning and geometry of the cable core 4.
  • the shielding film 10 is also initially supplied as a semi-finished product, i.e. without connected conductive layers 20, 22. These are only connected to one another in a perforating unit 30 . where is in 6 the perforating unit 30 is integrated into the spinning unit 28, so that the perforation and thus the contacting the conductive layers 20, 22 with one another only takes place immediately before the cable core 4 is wrapped.
