Definitions

  • cables with twisted-pair cables are used to transmit data or messages, the wires of which are twisted together in pairs. Twisted wire pairs enable an improved compensation of an influence of external magnetic alternating fields and electrostatic fields in comparison to wire pairs with only wires routed in parallel. As a result of twisting the wires of a pair of wires, influences from external electromagnetic fields largely cancel each other out. Wire pairs arranged within a cable can have different twists and a different sense of rotation. Different twists reduce crosstalk between adjacent wire pairs in a cable.

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 elektro-magnetischen Feldern bieten elektrisch leitende Schirme, die jeweils ein verdrilltes Aderpaar im Wesentlichen konzentrisch umgeben.In many cases, cables with twisted-pair cables are used to transmit data or messages, the wires of which are twisted together in pairs. Twisted wire pairs enable an improved compensation of an influence of external magnetic alternating fields and electrostatic fields in comparison to wire pairs with only wires routed in parallel. As a result of twisting the wires of a pair of wires, influences from external electromagnetic fields largely cancel each other out. Wire pairs arranged within a cable can have different twists and a different sense of rotation. Different twists reduce crosstalk between adjacent wire pairs in a cable. Additional protection against disturbing electro-magnetic fields is provided by electrically conductive shields, each of which essentially concentrically surrounds a twisted pair.

Aus EP 0 828 259 A2 ist ein Datenkabel mit zumindest einer Doppelleitung bekannt, die ein Aderpaar umfasst, das aus zwei miteinander verdrillten Einzeladern besteht, die jeweils einen Leiter und eine den Leiter umschließende Aderisolierung aufweisen. Außerdem sind ein das Aderpaar umgebender Zwischenmantel und eine den Zwischenmantel umgebende Abschirmung vorgesehen. Dabei füllt der Zwischenmantel Einkerbungen zwischen den Oberflächen der Einzeladern des Aderpaares zumindest teilweise aus, so dass er die Geometrie der Doppelleitung fixiert.Out EP 0 828 259 A2 a data cable with at least one double line is known, which comprises a pair of wires which consists of two twisted single wires, each having a conductor and a wire insulation surrounding the conductor. In addition, an intermediate jacket surrounding the pair of wires and a shield surrounding the intermediate jacket are provided. The intermediate sheath at least partially fills in notches between the surfaces of the individual wires of the pair of wires, so that it fixes the geometry of the double line.

In WO 99/60578 A1 ist ein Kabel beschrieben, das mindestens ein Paar von Adern mit Aderisolierung enthält. Eine erste Trennschicht ist um die Aderisolierungen gelegt. Hierum ist ein Innenmantel hohlraumfrei so gelegt, dass ein Aufbau mit einer im Querschnitt kreisförmigen Außenkontur entsteht. Schließlich sind ein Schirmgeflecht und ein äußerer Kabelmantel ringförmig um den Innenmantel gelegt.In WO 99/60578 A1 describes a cable that contains at least one pair of wires with wire insulation. A first separation layer is placed around the wire insulation. An inner jacket is placed around the cavity so that a structure with an outer contour that is circular in cross section is created. Finally, a screen braid and an outer cable jacket are placed in a ring around the inner jacket.

Aus EP 2 439 751 A2 ist ein Datenübertragungskabel mit mehreren jeweils separat abgeschirmten Aderpaaren bekannt, die jeweils von einer axial segmentierten Abschirmung umgeben sind. Die Abschirmung umfaßt zahlreiche Segmente, die auf ein beispielsweise durch Extrusion über ein Aderpaar gezogenes dielektrisches Substrat aufgebracht sind. Das Substrat kann beispielsweise aus einem nichtleitenden Material sein und verwobene oder nicht verwobene Fiberglas-Stränge umfassen, welche die Abschirmung verhältnismäßig starr machen. Darüber hinaus sind die jeweils von einer separaten Abschirmung umgebenen Aderpaare von einer gemeinsamen äußeren Abschirmung umhüllt, die wiederum von einem Außenmantel umgeben ist.Out EP 2 439 751 A2 a data transmission cable with several separately shielded wire pairs is known, each of which is surrounded by an axially segmented shield. The shield comprises numerous segments which are applied to a dielectric substrate which is drawn, for example, by extrusion over a pair of wires. The substrate can be made of a non-conductive material, for example, and can include woven or non-woven fiberglass strands that make the shield relatively rigid. In addition, 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 betrifft ein schnell konfektionierbares Datenübertragungskabel mit mehreren jeweils separat abgeschirmten Aderpaaren, die jeweils in eine erste isolierende Füllmasse eingebettet sind. Außerdem ist jeweils eine die erste isolierende Füllmasse umhüllende Abschirmung eines Aderpaars vorgesehen. Sämtliche Aderpaare sind von einem äußeren Geflechtschirm umgeben, der eine zweite isolierende Füllmasse umgibt, in welche die Aderpaare eingebettet sind. Der Geflechtschirm ist wiederum durch einen Außenmantel des Datenübertragungskabels umhüllt. EP 2 800 105 A1 relates to a quickly assembled data transmission cable with several separately shielded wire pairs, each of which is embedded in a first insulating filling compound. In addition, a shield of a pair of wires that envelops the first insulating filling compound is provided. All wire pairs are surrounded by an outer braid shield, which surrounds a second insulating filling compound, in which the wire pairs are embedded. The braid shield is in turn encased by an outer jacket of the data transmission cable.

In DE 10 2004 047384 B3 ist ein Kabel zur Übertragung von elektrischen Signalen beschrieben, das mindestens zwei Paare von nebeneinander liegenden Adern aufweist. Dabei ist jede Ader mit einer Aderisolierung versehen. Außerdem umfasst das Kabel ein elektrisch leitendes Aufteilelement, das den Innenquerschnitt des Kabels in eine der Anzahl von Aderpaaren entsprechende Anzahl offener Nuten unterteilt und in dessen Nuten jeweils ein Aderpaar angeordnet ist. Die Aderpaare und das Aufteilelement sind durch einen Kabelschirm im Wesentlichen ringförmig umhüllt. Dabei besteht zwischen dem Kabelschirm und den äußeren Kanten des Aufteilelements ein elektrischer Kontakt. Darüber hinaus ist ein äußerer Kabelmantel im Wesentlichen ringförmig um den Schirm gelegt.In 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. In addition, 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 which a wire pair is arranged in the grooves. The wire pairs and the dividing element are essentially encased in a ring by a cable shield. There is an electrical contact between the cable shield and the outer edges of the dividing element. In addition, an outer cable jacket is placed around the screen in a substantially ring shape.

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 rund. Mit schnell anschließ- bzw. konfektionierbaren Kabel können insbesondere Anforderungen entsprechend ISO/IEC 11801-2002, Kategorie 6 (Cat-6) erfüllt werden. Mittels eines als Aderpaar-Lagefixierungselement verwendeten zentralen Kunststoffkreuzes kann zudem ein Übersprechen der Aderpaare vermindert werden. Damit ist es möglich, Cat-6-Kabel mit einem SF/UTP-Aufbau (Screened Foiled, Unshielded Twisted Pair) zu realisieren, die einen äußeren Geflecht- und Folienschirm sowie Aderpaare mit ungeschirmten verdrillten Adern umfassen. Nachteil des Kunststoffkreuzes ist, dass es nach Abmanteln des Kabelaußenmantels und des Geflechtschirms sehr nah am Leitungsende abgeschnitten werden muss. Dies ist insbesondere bei einer Kabel-Konfektionierung am Verwendungsort des jeweiligen Kabels recht aufwendig bzw. schwierig.Quickly connectable or ready-to-assemble cables enable the outer jacket to be stripped and a braided shield surrounded by the outer jacket to be stripped by about 5 mm. For this purpose, the outer sheath and braided shield are ideally evenly round. With cables that can be connected and assembled quickly, requirements in accordance with ISO / IEC 11801-2002, Category 6 (Cat-6) can be met. Crosstalk between the wire pairs can also be reduced by means of a central plastic cross used as the wire pair position fixing element. This makes it possible to implement Cat-6 cables with an SF / UTP structure (Screened Foiled, Unshielded Twisted Pair), which include an outer braid and foil shield as well as wire pairs with unshielded twisted wires. The disadvantage of the plastic cross is that it has to be cut off very close to the cable end after the outer cable sheath and the braided shield have been stripped. This is particularly complex or difficult, particularly in the case of a cable assembly at the place of use of the respective cable.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein mehrere Aderpaare umfassendes Datenübertragungskabel insbesondere mit SF/UTP-Aufbau zu schaffen, das Anforderungen entsprechend ISO/IEC 11801-2002, Kategorie 6 erfüllt und einfach konfektioniert werden kann.The present invention is therefore based on the object, in particular a data transmission cable comprising a plurality of wire pairs to create with SF / UTP structure that meets the requirements of ISO / IEC 11801-2002, category 6 and can be easily assembled.

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.This object is achieved according to the invention by a data transmission cable which 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 weist mehrere Aderpaare auf, die jeweils ein Paar miteinander verdrillter Adern umfassen. Zusätzlich ist ein durch die Aderpaare umgebener und an diesen anliegender zentraler Beilauf vorgesehen, mittels dessen die Aderpaare zueinander ausgerichtet sind. Außerdem sind mehrere Bündel von Beilauf-Fäden äquidistant in Umfangsrichtung um die Aderpaare angeordnet. Jedes Bündel von Beilauf-Fäden ist an zwei jeweiligen zueinander benachbarten Aderpaaren anliegend angeordnet. Dabei sind die Aderpaare zueinander einerseits durch den zentralen Beilauf und andererseits durch die Bündel von Beilauf-Fäden fixiert.The data transmission cable according to the invention has a plurality of wire pairs, each of which comprises a pair of wires twisted together. In addition, a central bypass is provided, which is surrounded by the wire pairs and adjoins them, by means of which the wire pairs are aligned with one another. In addition, several bundles of filler threads are arranged equidistantly in the circumferential direction around the wire pairs. Each bundle of filler threads is arranged adjacent to two respective pairs of adjacent wires. The wire pairs are fixed to one another by the central drain and on the other hand by the bundle of drain threads.

Des weiteren umfasst das erfindungsgemäße Datenübertragungskabel einen die Bündel von Beilauf-Fäden und die Aderpaare umhüllenden Innenmantel sowie einen den Innenmantel umgebenden Geflechtschirm. Darüber hinaus ist ein den Geflechtschirm umhüllender Außenmantel des Datenübertragungskabels vorgesehen. Aufgrund des zentralen Beilaufs und der um die Aderpaare angeordneten Bündel von Beilauf-Fäden kann auf ein inneres Trennelement mit Kreuzprofil verzichtet werden, so dass eine einfache Konfektionierbarkeit erzielt wird. Insbesondere können der zentrale Beilauf und die Bündel von Beilauf-Fäden nach Abisolierung von Außenmantel und Geflechtschirm auf einfache Weise abgeschnitten werden.Furthermore, the data transmission cable according to the invention comprises an inner sheath enveloping the bundles of gimp threads and the wire pairs, and a braided shield surrounding the inner sheath. In addition, an outer sheath of the data transmission cable enveloping the braid shield is provided. Due to the central drain and the bundles of drain threads arranged around the wire pairs, an internal separating element with a cross profile can be dispensed with, so that it can be easily assembled. In particular, the central drain and the bundle of drain threads can be cut off easily after stripping the outer sheath and braid shield.

Die Aderpaare können beispielsweise jeweils eine separate Abschirmung aufweisen. In diesem Fall können die Abschirmungen der Aderpaare durch eine Aluminiumfolie, ein Metallgeflecht, insbesondere ein Kupfergeflecht, oder eine aluminiumkaschierte Kunststoffolie gebildet sein. Außerdem können die Aderpaare jeweils in eine isolierende Füllmasse eingebettet sein, die von der Abschirmung des jeweiligen Aderpaares umgeben ist.The wire pairs can each have a separate shield, for example. In this case, the shields of the wire pairs can be formed by an aluminum foil, a metal braid, in particular a copper braid, or an aluminum-clad plastic film. In addition, the wire pairs can each be embedded in an insulating filling compound, which is surrounded by the shielding of the respective wire pair.

Entsprechend einer vorteilhaften Ausgestaltung der vorliegenden Erfindung sind bzw. ist der zentrale Beilauf bzw. die Beilauf-Fäden aus Polyvinylchlorid, Polyethylen oder Aramid. Der Geflechtschirm kann beispielsweise aus Kupfer oder Aluminium sein. Vorzugsweise ist der Geflechtschirm von einer isolierenden Folie umgeben. Somit können einfach konfektionierbare Datenübertragungskabel in SF/UTP-Aufbautechnik realisiert werden. Der Außenmantel ist entsprechend einer weiteren Ausgestaltung des erfindungsgemäßen Datenübertragungskabels aus Polyvinylchlorid, Polyethylen oder Aramid.According to an advantageous embodiment of the present invention, the central filler or the filler threads are made of polyvinyl chloride, polyethylene or aramid. The braided shield can be made of copper or aluminum, for example. The braid shield is preferably surrounded by an insulating film. This means that easy-to-assemble data transmission cables can be implemented using SF / UTP technology. According to a further embodiment of the data transmission cable according to the invention, the outer jacket is made of polyvinyl chloride, polyethylene or aramid.

Darüber hinaus ist das Datenübertragungskabel in einer bevorzugten Ausführungsform als Cat-6-Kabel entsprechend ISO/IEC 11801 ausgestaltet und umfasst 4 Aderpaare. In diesem Fall sind 4 Bündel von Beilauf-Fäden vorsehen.In addition, in a preferred embodiment, the data transmission cable is configured as a Cat 6 cable in accordance with ISO / IEC 11801 and comprises 4 wire pairs. In this case, 4 bundles of filler threads should be provided.

Das in Figur 1 dargestellte Datenübertragungskabel ist aus DE 10 2004 047384 B3 bekannt sowie entsprechend ISO/IEC 11801-2002, Kategorie 6 ausgeführt und umfasst mehrere Aderpaare 101 mit verdrillten ungeschirmten Adern. Die Aderpaare 101 sind mittels eines inneren Kunststoff-Trennelements 102 mit Kreuzprofil zueinander lagefixiert und in definiertem Abstand angeordnet. Dabei sind die einzelnen Aderpaare 101 in jeweils einer Nut des Kunststoff-Trennelements 102 angeordnet. Durch den definierten Abstand der Aderpaare 101 wird insbesondere ein Übersprechen der Aderpaare 101 vermindert. Sämtliche Aderpaare 101 sowie das Kunststoff-Trennelement 102 sind radial von einem Innenmantel 103 umgeben, der wiederum von einem Geflechtschirm 104 umhüllt ist. Der Geflechtschirm 104 ist wiederum von einem Außenmantel 105 des Datenübertragungskabels umgeben.This in Figure 1 Data transmission cable shown is off DE 10 2004 047384 B3 known and designed in accordance with ISO / IEC 11801-2002, category 6 and comprises several wire pairs 101 with twisted unshielded wires. The wire pairs 101 are fixed to one another by means of an inner plastic separating element 102 with a cross profile and are arranged at a defined distance. The individual wire pairs 101 are each arranged in a groove in the plastic separating element 102. The defined spacing of the wire pairs 101 in particular reduces crosstalk between the wire pairs 101. All wire pairs 101 and the plastic separating element 102 are radially surrounded by an inner jacket 103, which in turn is encased by a braided shield 104. The braided shield 104 is in turn surrounded by an outer jacket 105 of the data transmission cable.

Zwar ermöglicht das in Figur 1 dargestellte Datenübertragungskabel ein Abisolieren des Außenmantels 105 und ein gleichzeitiges, um ca. 5 mm versetztes Abisolieren des Geflechtschirms 104. Allerdings muss das Kunststoff-Trennelement 102 nach Abisolieren des Außenmantels 105 und des Geflechtschirms 104 nah am Leitungsende mittels eines separaten Werkzeugs abgeschnitten werden. Daher ist mit dem in Figur 1 dargestellten Datenübertragungskabel keine schnelle Kabel-Konfektionierung möglich. Eine Kabel-Konfektionierung am jeweiligen Verwendungsort ist also erschwert, während ein Mitführen bereits vorkonfektionierter Kabel an den Verwendungsort angesichts eines dort erwartbaren Anpassungsbedarfs wenig praktikabels ist.Although this enables Figure 1 shown data transmission cable a stripping of the outer jacket 105 and a simultaneous, stripped by about 5 mm stripping of the braid shield 104. However, after stripping the outer jacket 105 and the braid shield 104, the plastic separating element 102 must be cut off close to the end of the line using a separate tool. Therefore, fast cable assembly is not possible with the data transmission cable shown in FIG. 1. Cable assembly at the respective place of use is therefore difficult, while carrying pre-assembled cables to the place of use is not very practical in view of the anticipated need for adaptation there.

Aus obigen Gründen wird bei dem in Figur 2 dargestellten Datenübertragungskabel auf ein Kunststoff-Trennelement verzichtet. Dieses Datenübertragungskabel ist im vorliegenden Ausführungsbeispiel als Cat-6A-Kabel entsprechend ISO/IEC 11801 ausgestaltet und weist 4 Aderpaare 201 auf, die jeweils ein Paar miteinander verdrillter Adern umfassen. Darüber hinaus ist ein durch die Aderpaare 201 umgebener und an diesen anliegender zentraler Beilauf 202 vorgesehen, mittels dessen die Aderpaare 201 zueinander ausgerichtet sind. Als Lagefixierungselement wirkt der zentrale Beilauf 202 mit insgesamt 4 Bündeln 203 von Beilauf-Fäden zusammen, welche in Umfangsrichtung jeweils 90° zueinander versetzt um die Aderpaare 201 angeordnet sind. Der zentrale Beilauf 202 und die Beilauf-Fäden können beispielsweise aus Polyvinylchlorid, Polyethylen oder Aramid sein. Jedes Bündel 203 von Beilauf-Fäden ist an zwei jeweiligen zueinander benachbarten Aderpaaren 201 anliegend angeordnet. Somit sind die Aderpaare 201 zueinander einerseits durch den zentralen Beilauf 202 und andererseits durch die Bündel 203 von Beilauf-Fäden fixiert. Auf diese Weise kann auf ein Kunststoff-Trennelement zwischen den Aderpaaren 201 verzichtet werden.For the above reasons, the in Figure 2 shown data transmission cable dispenses with a plastic separating element. In the present exemplary embodiment, this data transmission cable is configured as a Cat 6A cable in accordance with ISO / IEC 11801 and has 4 wire pairs 201, each of which comprises a pair of wires twisted together. In addition, a central bypass 202 is provided which is surrounded by the wire pairs 201 and bears against it, by means of which the wire pairs 201 are aligned with one another. The central drain 202 acts as a position-fixing element with a total of 4 bundles 203 of drain threads, which are arranged at 90 ° to the wire pairs 201 in the circumferential direction. The central drain 202 and the drain threads can be made of polyvinyl chloride, polyethylene or aramid, for example. Each bundle 203 of filler threads is arranged adjacent to two respective pairs of wires 201 that are adjacent to one another. Thus, the wire pairs 201 are fixed to one another on the one hand by the central drain 202 and on the other hand by the bundle 203 of drain threads. In this way, there is no need for a plastic separating element between the wire pairs 201.

Als zusätzliches Fixierungselement für die Aderpaare 201 wirkt ein die Bündel 203 von Beilauf-Fäden und die Aderpaare 201 umhüllender Innenmantel 204 aus isolierendem Material. Der Innenmantel 204 ist von einem Geflechtschirm 205 umgeben, der beispielsweise aus Kupfer oder Aluminium ist und wiederum von einer isolierenden Folie umgeben ist. Der folierte Geflechtschirm 205 ist schließlich von einem Außenmantel 206 des Datenübertragungskabels umhüllt. Der Außenmantel ist vorzugsweise aus Polyvinylchlorid, Polyethylen oder Aramid.An additional fixing element for the wire pairs 201 is an inner jacket 204 made of insulating material and enveloping the bundles 203 of gimp threads and the wire pairs 201. The inner jacket 204 is surrounded by a braided shield 205, which is made of copper or aluminum, for example, and is in turn surrounded by an insulating film. The foiled braided shield 205 is finally covered by an outer jacket 206 of the data transmission cable. The outer jacket is preferably made of polyvinyl chloride, polyethylene or aramid.

Grundsätzlich können die Aderpaare 201 jeweils eine separate Abschirmung aufweisen, die beispielsweise durch eine Aluminiumfolie, ein Metallgeflecht, insbesondere ein Kupfergeflecht, oder eine aluminiumkaschierte Kunststofffolie gebildet ist. Zusätzlich können die Aderpaare 201 jeweils in eine isolierende Füllmasse eingebettet sein, die von der Abschirmung des jeweiligen Aderpaares umgeben ist.In principle, the wire pairs 201 can each have a separate shielding, which is provided, for example, by an aluminum foil, a metal braid, in particular a copper braid, or an aluminum-clad plastic film is formed. In addition, the wire pairs 201 can each be embedded in an insulating filling compound which is surrounded by the shielding of the respective wire pair.

Zur Abisolierung des in Figur 2 dargestellten Datenübertragungskabels kann beispielsweise die Messerkassette Siemens 6GK1901-1GB01 als Abisolier- bzw. Konfektionierungswerkzeug verwendet werden. Zunächst wird eine abzuisolierende Leitungslänge am Abisolierwerkzeug abgemessen und das Datenübertragungskabel mit einer entsprechenden Länge in das Abisolierwerkzeug eingelegt. Das Abisolierwerkzeug wird anschließend gespannt und zum Abisolieren des Datenübertragungskabels mehrfach um dessen Längsachse gedreht. Hierdurch werden der Außenmantel und der Geflechtschirm an durch das Abisolierwerkzeug vorgegebenen Positionen in Umfangsrichtung angeschnitten. Durch eine Zugbewegung des Abisolierwerkzeugs in Längsrichtung zum Kabelende werden dann abzutrennende Teile des Außenmantels und des Geflechtschirms vom restlichen Datenübertragungskabel entfernt. Anschließend werden die Adern freigelegt und aufgefächert, so dass der zentrale Beilauf 202 sowie die Bündel 203 von Beilauf-Fäden abgeschnitten werden können. Abschließend kann das abisolierte Datenübertragungskabel mit seinen Adern zur Konfektionierung in ein Steckergehäuse eingeführt und dieses verriegelt werden. To strip the in Figure 2 The data transmission cable shown can, for example, use the Siemens 6GK1901-1GB01 knife cassette as a stripping or assembly tool. First, a cable 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 clamped and rotated several times around its longitudinal axis to strip the data transmission cable. As a result, the outer jacket and the braided shield are cut in the circumferential direction at positions specified by the stripping tool. By pulling the stripping tool in the longitudinal direction towards the cable end, parts of the outer sheath and the braided shield to be separated are then removed from the rest of the data transmission cable. The veins are then exposed and fanned out, so that the central drain 202 and the bundles 203 of drain threads can be cut off. Finally, the stripped data transmission cable with its wires can be inserted into a connector housing for assembly and locked.
