Definitions
- cables with twisted pairs of wires are often used, the wires of which are twisted together in pairs. Twisted wire pairs enable an improved compensation of the influence of external alternating magnetic fields and electrostatic fields in comparison to wire pairs with only parallel wires. As a result of the wires of a wire pair being twisted, influences from external electromagnetic fields largely cancel each other out. Wire pairs arranged within a cable can have different degrees of twisting and different directions of rotation. Twists of different strengths reduce crosstalk between adjacent pairs of wires in a cable. Electrically conductive shields, which each essentially concentrically surround a twisted pair of wires, offer additional protection against interfering electromagnetic fields.
- a data cable with at least one double wire which comprises a pair of wires which consists of two individual wires twisted together, each having a conductor and a wire insulation surrounding the conductor.
- an intermediate jacket surrounding the pair of wires and a shield surrounding the intermediate jacket are provided. The intermediate jacket at least partially fills notches between the surfaces of the individual cores of the core pair, so that it fixes the geometry of the double line.
- WO 99/60578 A1 describes a cable that contains at least one pair of wires with wire insulation.
- a first separating layer is placed around the core insulation.
- An inner jacket is placed around this without cavities in such a way that a structure with an outer contour that is circular in cross-section is created.
- a braided shield and an outer cable jacket are placed in a ring around the inner jacket.
- a data transmission cable with a plurality of separately shielded wire pairs is known, each of which is surrounded by an axially segmented shield.
- the shielding comprises numerous segments which are applied to a dielectric substrate drawn over a pair of wires, for example by extrusion.
- the substrate can for example be made of a non-conductive material and comprise woven or non-woven fiberglass strands which make the shield relatively rigid.
- the wire pairs each surrounded by a separate shield are encased by a common outer shield, which in turn is surrounded by an outer jacket.
- EP 2 800 105 A1 relates to a data transmission cable that can be assembled quickly and has several separately shielded wire pairs, each of which is embedded in a first insulating filler compound.
- a shielding of a pair of wires that envelops the first insulating filler compound is provided in each case. All wire pairs are surrounded by an outer braided shield which surrounds a second insulating filling compound in which the wire pairs are embedded.
- the braided shield is in turn covered by an outer sheath of the data transmission cable.
- DE 10 2004 047384 B3 describes a cable for the transmission of electrical signals, which has at least two pairs of adjacent wires. Each wire is provided with wire insulation.
- the cable comprises an electrically conductive dividing element, which divides the inner cross-section of the cable into a number of open grooves corresponding to the number of wire pairs and in each of the grooves a wire pair is arranged.
- the wire pairs and the dividing element are encased in a substantially ring-shaped manner by a cable shield. There is an electrical contact between the cable shield and the outer edges of the dividing element.
- an outer cable sheath is placed around the screen in a substantially ring-shaped manner.
- Cables that can be quickly connected or assembled enable the outer sheath to be stripped and a braided shield surrounded by the outer sheath of the cable to be stripped at the same time, offset by approx. 5 mm.
- the outer sheath and braided shield are ideally evenly circular.
- it is relatively easy to realize circular cable cross-sections so that such cables can be easily made with an assembly tool can be stripped.
- a circular cable cross-section is difficult to achieve, especially in the case of twisted wires. Stripping a cable end with an assembly tool is therefore not easily possible. Accordingly, cables with only one wire pair have previously had to be stripped in a time-consuming manner and essentially without suitable tools.
- the present invention is therefore based on the object of creating a data transmission cable comprising only one pair of wires, which can be stripped quickly, easily and safely in one work step by means of an assembly tool.
- the data transmission cable according to the invention which can be assembled, in particular a 2-wire Ethernet cable, has exactly one pair of wires which comprises two conductors that are twisted together and are embedded in an insulating filler compound.
- a fixing tube surrounding the insulating filler compound is provided, which has a circular cross-section.
- the insulating filler material forms a sheathing of the wire pair with a round cross-section through the fixing tube.
- the fixing tube is preferably extruded around the insulating filler compound.
- the data transmission cable according to the invention has a shield for the wire pair that surrounds the fixing tube.
- the data transmission cable comprises a shield enveloping outer jacket.
- the data transmission cable according to the invention thus has a design which is very well suited for stripping by means of a conventional assembly tool. This design is significantly influenced in particular by the fixation tube.
- the data transmission cable can be stripped by removing the outer jacket and exposing the shield using a cutting tool set to a first diameter and by removing the shield and the fixing tube axially offset thereto using the cutting tool set to a second diameter.
- the first diameter is larger than the second diameter.
- the fixing tube and the insulating filling compound are designed and arranged in such a way that damage to the wire pair is avoided in the event of an axially offset simultaneous stripping of the outer jacket and the fixing tube.
- the insulating filling compound advantageously has a first cut resistance value, while the fixing tube has a second cut resistance value which is higher than the first cut resistance value. In this way, the filling compound and wire pair are protected from cutting or stabbing loads by the fixing tube.
- the shield can be formed, for example, by a braided or foil shield.
- the shield is preferably formed by an aluminum foil, a metal mesh, in particular a copper mesh, or an aluminum-laminated plastic film.
- the outer jacket is made of polyvinyl chloride, polyethylene or aramid.
- the data transmission cable shown is designed as a 2-wire Ethernet cable and comprises exactly one wire pair 100 with two twisted unshielded conductors 101-102.
- the two conductors 101-102 are embedded in an insulating filling compound 103, which is surrounded axially and radially by a fixing tube 104 (see also Figure 2 ).
- the fixing tube 104 has a circular cross section, so that the insulating filler compound 103 forms a sheathing of the wire pair 100 with a round cross section through the fixing tube 104.
- the fixing tube 104 is extruded around the insulating filler compound 103.
- the fixing tube 104 is in turn surrounded by a shield 105 for the wire pair 100.
- the shield 105 is formed by a braided shield, which is made, for example, of copper or aluminum and is in turn surrounded by an insulating film.
- the shield 105 can also be formed by an aluminum foil, a metal mesh, in particular a copper mesh, or an aluminum-laminated plastic film.
- the shield 105 is finally sheathed by an outer jacket 106 of the data transmission cable.
- the outer jacket 106 is preferably made of polyvinyl chloride, polyethylene or aramid.
- the fixing tube 104 and the insulating filler compound 103 are designed and arranged in such a way that damage to the wire pair 100 is avoided in the event of an axially offset stripping of the outer jacket 106 and the fixing tube 104.
- the insulating filling compound 103 can have a first cut resistance value for this purpose, while the fixing tube 104 advantageously has a second cut resistance value which is higher than the first cut resistance value.
- the data transmission cable shown is preferably made by removing the outer sheath 106 and exposing the shield 105 by means of a cutting tool set to a larger first diameter and by removing the shield 105 and the fixing tube 104 axially offset thereto by means of the cutting tool set to a smaller second diameter Figure 3 stripped.
- the outer jacket 106 on the one hand and the shield 105 including the fixing tube 104 on the other hand can be removed at a predetermined distance 107 in one work step. In this way, a simple and quick preparation of a cable end for mounting in a plug is possible.
- the Siemens 6GK1901-1GB01 knife cassette for example, can be used as a stripping tool for stripping the data transmission cable. or assembly tools can be used.
- a line length to be stripped is measured on the stripping tool and the data transmission cable is inserted into the stripping tool with a corresponding length.
- the stripping tool is then tensioned and rotated several times around its longitudinal axis in order to strip the insulation off the data transmission cable.
- the outer jacket 106 and the shield 105 including the fixing tube 104 are cut in the circumferential direction at positions predetermined by the stripping tool.
- the stripping tool By pulling the stripping tool in the longitudinal direction towards the end of the cable, parts of the outer jacket 106 and the shielding 105 or the fixing tube 104 that are to be separated are then removed from the rest of the data transmission cable.
- the lines 101-102 are then exposed by removing the insulating filler compound 103 and fanned out. Finally, the stripped data transmission cable with its lines 101-102 can be inserted into a connector housing for assembly and this can be locked.

Description
Zur Übertragung von Daten oder Nachrichten werden vielfach Kabel mit verdrillten Aderpaaren (Twisted-Pair-Kable) verwendet, deren Adern jeweils paarweise miteinander verdrillt sind. Verdrillte Aderpaare ermöglichen eine verbesserte Kompensation eines Einflusses äußerer magnetischer Wechselfelder und elektrostatischer Felder im Vergleich zu Aderpaaren mit lediglich parallel geführten Adern. Infolge eines Verdrillens von Adern eines Aderpaars heben sich Beeinflussungen durch äußere elektro-magnetische Felder weitestgehend gegenseitig auf. Innerhalb eines Kabels angeordnete Aderpaare können eine unterschiedlich starke Verdrillung und einen unterschiedlichen Drehsinn aufweisen. Unterschiedlich starke Verdrillungen reduzieren ein Übersprechen zwischen benachbarten Aderpaaren in einem Kabel. Einen zusätzlichen Schutz gegenüber störenden elektromagnetischen Feldern bieten elektrisch leitende Schirme, die jeweils ein verdrilltes Aderpaar im Wesentlichen konzentrisch umgeben.For the transmission of data or messages, cables with twisted pairs of wires are often used, the wires of which are twisted together in pairs.

Schnell anschließ- bzw. konfektionierbare Kabel ermöglichen ein Abmanteln eines Kabelaußenmantels und ein gleichzeitiges, um ca. 5 mm versetztes Abmanteln eines vom Kabelaußenmantel umgebenen Geflechtschirms. Hierzu sind Außenmantel und Geflechtschirm idealerweise gleichmäßig kreisrund. Bei mehradrigen Kabeln mit üblicherweise 4 oder 8 Adern ist es relativ einfach möglich, kreisrunde Kabelquerschnitte zu realisieren, so dass derartige Kabel recht problemlos mit einem Konfektionierungswerkzeug abisoliert werden können. Bei Kabeln mit jeweils mit nur einem Aderpaar ist ein kreisrunder Kabelquerschnitt nur schwer zu realisieren, insbesondere bei verdrillten Adern. Ein Abmanteln eines Kabelendes mit einem Konfektionierungswerkzeug ist somit nicht ohne Weiteres möglich. Dementsprechend müssen Kabel mit nur einem Aderpaar bisher zeitaufwendig und im Wesentlichen ohne geeignete Werkzeuge abisoliert werden.Cables that can be quickly connected or assembled enable the outer sheath to be stripped and a braided shield surrounded by the outer sheath of the cable to be stripped at the same time, offset by approx. 5 mm. For this purpose, the outer sheath and braided shield are ideally evenly circular. In the case of multi-core cables with usually 4 or 8 cores, it is relatively easy to realize circular cable cross-sections, so that such cables can be easily made with an assembly tool can be stripped. In the case of cables with only one pair of wires each, a circular cable cross-section is difficult to achieve, especially in the case of twisted wires. Stripping a cable end with an assembly tool is therefore not easily possible. Accordingly, cables with only one wire pair have previously had to be stripped in a time-consuming manner and essentially without suitable tools.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein lediglich ein Aderpaar umfassendes Datenübertragungskabel zu schaffen, das sich schnell, einfach und sicher in einem Arbeitsschritt mittels eines Konfektionierungswerkzeugs abisolieren lässt.The present invention is therefore based on the object of creating a data transmission cable comprising only one pair of wires, which can be stripped quickly, easily and safely in one work step by means of an assembly tool.
Diese Aufgabe wird erfindungsgemäß durch ein konfektionierbares Datenübertragungskabel mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den abhängigen Ansprüchen angegeben.According to the invention, this object is achieved by a data transmission cable that can be assembled and has the features specified in claim 1. Advantageous developments of the present invention are specified in the dependent claims.
Das erfindungsgemäße konfektionierbare Datenübertragungskabel, insbesondere ein 2-Draht-Ethernet-Kabel, weist genau ein Aderpaar auf, das zwei miteinander verdrillte Leiter umfasst, die in eine isolierende Füllmasse eingebettet sind. Außerdem ist ein die isolierende Füllmasse umgebender Fixierungsschlauch vorgesehen, der einen kreisrunden Querschnitt aufweist. Dabei bildet die isolierende Füllmasse durch den Fixierungsschlauch eine querschnittsrunde Ummantelung des Aderpaars. Vorzugsweise ist der Fixierungsschlauch um die isolierende Füllmasse extrudiert. Darüber hinaus weist das erfindungsgemäße Datenübertragungskabel eine den Fixierungsschlauch umgebende Abschirmung für das Aderpaar auf. Des Weiteren umfasst das Datenübertragungskabel ein die Abschirmung umhüllenden Außenmantel. Somit weist das erfindungsgemäße Datenübertragungskabel eine Gestaltung auf, die für ein Abisolieren mittels eines herkömmlichen Konfektionierungswerkzeugs sehr gut geeignet ist. Diese Gestaltung wird insbesondere durch den Fixierungsschlauch maßgeblich beeinflusst.The data transmission cable according to the invention, which can be assembled, in particular a 2-wire Ethernet cable, has exactly one pair of wires which comprises two conductors that are twisted together and are embedded in an insulating filler compound. In addition, a fixing tube surrounding the insulating filler compound is provided, which has a circular cross-section. The insulating filler material forms a sheathing of the wire pair with a round cross-section through the fixing tube. The fixing tube is preferably extruded around the insulating filler compound. In addition, the data transmission cable according to the invention has a shield for the wire pair that surrounds the fixing tube. Furthermore, the data transmission cable comprises a shield enveloping outer jacket. The data transmission cable according to the invention thus has a design which is very well suited for stripping by means of a conventional assembly tool. This design is significantly influenced in particular by the fixation tube.
Vorteilhafterweise ist das Datenübertragungskabel durch Entfernen des Außenmantels und Freilegen der Abschirmung mittels eines auf einen ersten Durchmesser eingestellten Schneidewerkzeugs sowie durch ein axial dazu versetztes Entfernen der Abschirmung und des Fixierungsschlauchs mittels des auf einen zweiten Durchmesser eingestellten Schneidewerkzeugs abisolierbar. Insbesondere ist der erste Durchmesser größer als der zweite Durchmesser.Advantageously, the data transmission cable can be stripped by removing the outer jacket and exposing the shield using a cutting tool set to a first diameter and by removing the shield and the fixing tube axially offset thereto using the cutting tool set to a second diameter. In particular, the first diameter is larger than the second diameter.

Vorteilhafterweise weist die isolierende Füllmasse einen ersten Schnittfestigkeitswert auf, während der Fixierungsschlauch einen zweiten Schnittfestigkeitswert aufweist, der höher als der erste Schnittfestigkeitswert ist. Auf diese Weise werden Füllmasse und Aderpaar durch den Fixierschlauch vor Schnitt- oder Stichbelastungen geschützt.According to a preferred embodiment of the present invention, the fixing tube and the insulating filling compound are designed and arranged in such a way that damage to the wire pair is avoided in the event of an axially offset simultaneous stripping of the outer jacket and the fixing tube. The insulating filling compound advantageously has a first cut resistance value, while the fixing tube has a second cut resistance value which is higher than the first cut resistance value. In this way, the filling compound and wire pair are protected from cutting or stabbing loads by the fixing tube.
Die Abschirmung kann beispielsweise durch einen Geflecht- bzw. Folienschirm gebildet sein. Vorzugsweise ist die Abschirmung durch eine Aluminiumfolie, ein Metallgeflecht, insbesondere ein Kupfergeflecht, oder eine aluminiumkaschierte Kunststofffolie gebildet.
