Definitions
- the invention relates to a multilayer, strip-shaped shielding film for multi-core data transmission cables, with at least one carrier layer of a plastic and at least one shielding layer connected to the carrier layer of an electrically conductive material, in particular of metal. Furthermore, the invention relates to a data transmission cable, with at least one line, but in particular with a plurality of twisted pair lines, so-called "twisted pairs", in which the aforementioned shielding film is used.
- a cable with such a shielding is from the US 2003/0217863 A1 known.
- Common data transmission cables use several, for example, four of the above-mentioned twisted pairs, which must be shielded with increasing category of transmission bandwidth and transmission quality. Both the outer shielding of the twisted pairs as a whole, as well as the mutual shielding of the twisted pairs in a cable plays a role.
- a shielding foil which consists of a laminate consisting of a carrier layer of a plastic and a laminated thereon shielding layer consists of metal.
- this laminate film can be folded into an outer shielding sheath placed around several twisted pairs and, for example, a star-shaped internal separating and supporting structure.
- the shielding film is designed so that it has a continuous shielding layer of, for example, aluminum or copper as a strip-shaped material in the strip longitudinal direction.
- the invention has the object, a shielding for multi-wire data transmission cable in such a way that while it retains its shielding properties substantially unimpaired, but completely avoids the above grounding problem.
- the pitch gaps return at periodic intervals.
- the measure ratio of gap width to the length of the gap between the gap gaps remaining pieces of film is preferably in the range between 1: 5 and 1:25, with typical film lengths in the range of 60 to 120 mm and typical Abstandsspaltbreiten in the range of 5 to 10 mm.
- the corresponding geometric values are to be designed in such a way that no characteristic impedance peaks or return loss peaks occur in the transmission frequency range of the data transmission cable due to the periodicity of the structure.
- successive spacing gaps are arranged at a preferably small acute angle to the strip transverse direction. With alternate angular position, the pieces of film remaining between the spacing gaps are then trapezoidal.
- This embodiment has the advantage that in a winding of such AblefolienstMail about its longitudinal axis to form a tubular casing, the spacing gaps run helically, which brings in interruption of the current path in the longitudinal direction relative to the strictly perpendicular to the strip longitudinal direction columns advantages in Able with it.
- the pieces of film remaining therebetween are parallelogram-shaped.
- This embodiment allows for application of the shielding film in the longitudinal direction of the cable axis, a gap which rotates as a helix about the cable axis.
- Bandierstrom or during the stranding of the cable while the acute angle of the gap gaps can be designed to the strip transverse direction so that a compensation leads to the stranding angle to a cylindrical metal-free gap.
- a particularly robust embodiment with a high protection for the sensitive metallic shielding layer results from a lamination of the shielding layer between two carrier layers.
- the protective effect is further improved if these carrier layers protrude beyond the longitudinal edges of the shielding layer and are connected to one another there.
- the invention also relates to a data transmission cable, wherein the outer envelope and / or an inner supporting and separating structure consists of the shielding foil in one of the embodiments discussed above.
- the outer enclosure protects the overall environment against against emitted from the cable energies and existing in the cable transmission elements, for example in the form of several twisted pairs, against irradiated interference energy.
- the latter aspect is of particular importance in the application of 10GB Ethernet on copper data transmission cables. Namely, the so-called "cable crosstalk" - also referred to as alien NEXT or alien EL-FEXT - drastically reduced by the outer sheath.
- the internal crosstalk between the individual twisted pairs is achieved by integrating the shielding foil into an inner supporting and separating structure, such as, for example, by folding the shielding foil into an inlay Profile four-armed star configuration can be drastically reduced. Due to the flexibility of the shielding film, it can be placed in virtually any configuration and adapted to a wide variety of line assignments within the cable. A variety of examples in which, however, nowhere a shielding film is used with in the longitudinal direction interrupted shielding layer is, inter alia, the publications US Pat. No. 6,624,359 B2 . US 2003/0217863 A1 or EP 0 915 486 A1 removable.
- Fig. 1 the basic structure of a multilayer, strip-shaped shielding foil 1 becomes clear.
- This has a first carrier layer 2 of a continuous, strip-shaped plastic material, such as preferably polyester, a thickness of 9 to 50 microns.
- a shielding layer 3 is laminated, which consists of individual metal foil pieces 4, which are separated by a gap 5 from each other.
- These rectangular pieces of film have a typical length L in the strip longitudinal direction Z, which is 60 to 120 mm.
- the gap width D in strip longitudinal direction Z is typically about 5 to 10 mm, so that the measurement ratio of gap width D to length L of the film pieces 4 is between 1: 5 and 1:25.
- the width of the film pieces 4 is slightly smaller than that of the carrier layer 2, so that the longitudinal edges 6 of the carrier layer 2 protrude beyond the longitudinal edges 7 of the shielding layer 3 by a few millimeters.
- the metal foil of the shielding layer 3 is preferably made of aluminum with a layer thickness between 5 and 50 microns.
- a further carrier layer 8 is laminated, so that a kind of film sandwich is formed.
- the carrier layer 8 is made of the same material as the carrier layer 2 and is fixedly connected to the lower carrier layer 2 in the region of the longitudinal edges protruding laterally beyond the shielding layer 3.
- the shielding layer 3 is hermetically sealed to the outside.
- the permanent connection of the three layers 2, 3, 8 takes place by means of suitable adhesive materials, which are customary in the field of laminating films.
- the carrier layer 2 can be made of a uniform material for manufacturing and stability reasons multi-layered.
- the longitudinal edges 6 of the carrier layers 2, 8 and the longitudinal edges 7 of the shielding layer 3 also terminate flush with each other, so that the longitudinal edge 7 of the shielding layer 3 remains accessible and recognizable from the outside.

Description
Die Erfindung betrifft eine mehrlagige, streifenförmige Abschirmfolie für mehradrige Datenübertragungskabel, mit mindestens einer Trägerlage aus einem Kunststoff und mindestens einer mit der Trägerlage verbundenen Abschirmlage aus einem elektrisch leitfähigen Material, insbesondere aus Metall. Ferner bezieht sich die Erfindung auf ein Datenübertragungskabel, mit mindestens einer Leitung, insbesondere jedoch mit mehreren verdrillten Paar-Leitungen, sogenannten "twisted pairs", in der die eingangs genannte Abschirmfolie eingesetzt ist. Ein Kabel mit einer solchen Abschirmfolie ist aus der
Die der Erfindung zugrundeliegende Problematik lässt sich am augenscheinlichsten anhand von Hochgeschwindigkeits-Datenübertragungskabeln erläutern, was die Anwendung der Erfindung jedoch nicht auf diesen Zweck beschränkt.The problem underlying the invention can be explained most obviously by means of high-speed data transmission cables, which does not limit the application of the invention to this purpose.
Gängige Datenübertragungskabel verwenden mehrere, beispielsweise vier der oben erwähnten twisted pairs, die bei steigender Kategorie der Übertragungsbandbreite und Übertragungsgüte geschirmt sein müssen. Dabei spielt sowohl die äußere Schirmung der twisted pairs insgesamt, als auch die gegenseitige Abschirmung der twisted pairs in einem Kabel eine Rolle.Common data transmission cables use several, for example, four of the above-mentioned twisted pairs, which must be shielded with increasing category of transmission bandwidth and transmission quality. Both the outer shielding of the twisted pairs as a whole, as well as the mutual shielding of the twisted pairs in a cable plays a role.
Zur Erzielung entsprechender Spezifikationen von Übertragungsbandbreite und Übertragungsgüte ist es beispielsweise aus der
Die vorstehende Auslegung mit in Kabellängsrichtung durchgehender, elektrisch leitender Abschirmlage führt nun zu einer Erdungsproblematik, da bei unterschiedlichen Potentialen an den Enden einer Leitung hohe Potentialausgleichsströme durch die Schirmung laufen können. Diese verursachen ihrerseits Störungen und unter Umständen sogar Schäden an den mit einem solchen Datenübertragungskabel verbundenen Geräten.The above design with an electrically conductive shielding layer which extends continuously in the cable longitudinal direction now leads to a grounding problem since high equipotential bonding currents can pass through the shielding at different potentials at the ends of a line. These, in turn, cause interference and possibly even damage to the devices connected to such a data transmission cable.
Aus der
Ausgehend von der oben erörterten Problematik liegt der Erfindung die Aufgabe zugrunde, eine Abschirmfolie für mehradrige Datenübertragungskabel so auszugestalten, dass sie zwar ihre Abschirmungseigenschaften im wesentlichen unbeeinträchtigt behält, jedoch die vorstehende Erdungsproblematik vollständig vermeidet.Based on the above-discussed problem, the invention has the object, a shielding for multi-wire data transmission cable in such a way that while it retains its shielding properties substantially unimpaired, but completely avoids the above grounding problem.
Diese Aufgabe wird dadurch gelöst, dass die streifenförmige Abschirmfolie quer zur Streifenlängsrichtung verlaufende, in Längsabständen wiederkehrende Abstandsspalte in der Abschirmlage aufweist, die deren elektrische Unterbrechung in Streifenlängsrichtung dienen. Es existiert also in Längsrichtung der Abschirmfolie keine durchgehend elektrisch leitende Verbindung, was das Fließen von Potentialausgleichsströmen vollständig unterbindet. Da die Spalte jedoch im Vergleich zur verbleibenden Schirmfläche der zwischen den Abstandsspalten liegenden Folienstücke klein bleibt, wird keine signifikante Verschlechterung des Schirmverhaltens der Abschirmfolie festzustellen sein.This object is achieved in that the strip-shaped shielding film extending transversely to the strip longitudinal direction, in longitudinal intervals recurring distance gaps in the shielding layer, which serve their electrical interruption in the strip longitudinal direction. Thus, there is no continuous electrically conductive connection in the longitudinal direction of the shielding foil, which completely prevents the flow of equipotential bonding currents. As the column, however, compared to the remaining screen area the gap between the gap gaps remains small, no significant deterioration of the shield behavior of the shielding be determined.
Gemäß einer bevorzugten Ausführungsform der Erfindung kehren die Abstandsspalte in periodischen Abständen wieder. Das Maßverhältnis von Abstandsspaltbreite zur Länge der zwischen den Abstandsspalten verbleibenden Folienstücke liegt dabei vorzugsweise im Bereich zwischen 1:5 und 1:25, wobei typische Folienstücklängen im Bereich von 60 bis 120 mm und typische Abstandsspaltbreiten im Bereich von 5 bis 10 mm liegen können. In der Praxis sind die entsprechenden geometrischen Werte derart auszulegen, dass im Übertragungsfrequenzbereich des Datenübertragungskabels keine Wellenwiderstandsspitzen oder Rückflussdämpfungsspitzen aufgrund der Periodizität der Struktur auftreten.According to a preferred embodiment of the invention, the pitch gaps return at periodic intervals. The measure ratio of gap width to the length of the gap between the gap gaps remaining pieces of film is preferably in the range between 1: 5 and 1:25, with typical film lengths in the range of 60 to 120 mm and typical Abstandsspaltbreiten in the range of 5 to 10 mm. In practice, the corresponding geometric values are to be designed in such a way that no characteristic impedance peaks or return loss peaks occur in the transmission frequency range of the data transmission cable due to the periodicity of the structure.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind aufeinanderfolgende Abstandsspalten in einem vorzugsweise kleinen spitzen Winkel zur Streifenquerrichtung angeordnet. Bei wechselweiser Winkellage sind die zwischen den Abstandsspalten verbleibenden Folienstücke dann trapezförmig. Diese Ausgestaltung hat den Vorteil, dass bei einem Wickeln derartiger Abschirmfolienstreifen um ihre Längsachse zur Bildung einer Schlauchhülle die Abstandsspalten helixförmig verlaufen, was bei Unterbrechung des Strompfades in Längsrichtung gegenüber den streng rechtwinklig zur Streifenlängsrichtung verlaufenden Spalten Vorteile im Abschirmverhalten mit sich bringt.According to a further preferred embodiment of the invention, successive spacing gaps are arranged at a preferably small acute angle to the strip transverse direction. With alternate angular position, the pieces of film remaining between the spacing gaps are then trapezoidal. This embodiment has the advantage that in a winding of such Abschirmfolienstreifen about its longitudinal axis to form a tubular casing, the spacing gaps run helically, which brings in interruption of the current path in the longitudinal direction relative to the strictly perpendicular to the strip longitudinal direction columns advantages in Abschirmverhalten with it.
Bei zueinander parallelen Winkellagen der Abstandsspalten zur Streifenquerrichtung sind die dazwischen verbleibenden Folienstücke parallelogrammförmig. Diese Ausführungsform erlaubt bei Aufbringung der Abschirmfolie in Längsrichtung zur Kabelachse einen Spalt, der als Helix um die Kabelachse rotiert. Bei Aufbringung der Folie mit einer sogenannten Bandieranlage oder während der Verseilung des Kabels kann dabei der spitze Winkel der Abstandsspalte zur Streifenquerrichtung so ausgelegt werden, dass eine Kompensation mit dem Verseilwinkel zu einem zylindrischen metallfreien Spalt führt.In the case of mutually parallel angular positions of the spacing gaps relative to the strip transverse direction, the pieces of film remaining therebetween are parallelogram-shaped. This embodiment allows for application of the shielding film in the longitudinal direction of the cable axis, a gap which rotates as a helix about the cable axis. When applying the film with a so-called Bandieranlage or during the stranding of the cable while the acute angle of the gap gaps can be designed to the strip transverse direction so that a compensation leads to the stranding angle to a cylindrical metal-free gap.
Eine besonders robuste Ausführungsform mit einem hohen Schutz für die empfindliche metallene Abschirmlage ergibt sich durch eine Einlaminierung der Abschirmlage zwischen zwei Trägerlagen. Der Schutzeffekt wird noch verbessert, wenn diese Trägerlagen über die Längsränder der Abschirmlage hinausstehen und dort miteinander verbunden sind.A particularly robust embodiment with a high protection for the sensitive metallic shielding layer results from a lamination of the shielding layer between two carrier layers. The protective effect is further improved if these carrier layers protrude beyond the longitudinal edges of the shielding layer and are connected to one another there.
Die Erfindung bezieht sich auch auf ein Datenübertragungskabel, wobei die äußere Umhüllung und/oder eine innere Stütz- und Separierstruktur aus der Abschirmfolie in einer der vorstehend erörterten Ausführungsfbrmen besteht. Die äußere Umhüllung schützt als Gesamtschirm dabei die Umgebung gegen aus dem Kabel abgestrahlte Energien und die im Kabel vorhandenen Übertragungselemente, beispielsweise in Form mehrerer twisted pairs, gegen eingestrahlte Störenergie. Insbesondere letzterem Aspekt kommt bei der Anwendung des 10GB-Ethernet auf Kupfer-Datenübertragungskabeln eine besondere Bedeutung zu. Durch die äußere Umhüllung wird nämlich das sogenannte "Kabelübersprechen" ― auch als Alien-NEXT bzw. Alien-EL-FEXT bezeichnet ― drastisch reduziert.The invention also relates to a data transmission cable, wherein the outer envelope and / or an inner supporting and separating structure consists of the shielding foil in one of the embodiments discussed above. The outer enclosure protects the overall environment against against emitted from the cable energies and existing in the cable transmission elements, for example in the form of several twisted pairs, against irradiated interference energy. In particular, the latter aspect is of particular importance in the application of 10GB Ethernet on copper data transmission cables. Namely, the so-called "cable crosstalk" - also referred to as alien NEXT or alien EL-FEXT - drastically reduced by the outer sheath.
Das kabelinterne Übersprechen zwischen den einzelnen twisted pairs wird durch die Integration der Abschirmfolie in eine innere Stütz- und Separierstruktur, wie sie beispielsweise durch Falten der Abschirmfolie in eine im Profil vierarmige Sternkonfiguration erfolgen kann, drastisch verringert. Aufgrund der Flexibilität der Abschirmfolie kann diese praktisch in beliebige Konfigurationen gelegt und an unterschiedlichste Leitungsbelegungen innerhalb des Kabels angepasst werden. Eine Vielzahl von Beispielen, bei denen jedoch nirgends eine Abschirmfolie mit in Längsrichtung unterbrochener Abschirmlage eingesetzt wird, ist unter anderem den Druckschriften
