For example, in the Fig. 6 of the DE 199 51 455 C1 and Fig.1 of the DE 10 2011 108 123 A1 shown cable connection component, the individual wires of the cable are first introduced into the splice part, which is referred to there as a wire receiving and -führungsteil. Then the wire ends are bent and inserted into recesses in the splice part, which serve as restraint locks for the wires during radial deflection. Subsequently, the protruding through the recesses wire ends are cut off, so that then the union nut can be screwed onto the corresponding external thread of a connector body. When screwing the union nut onto the connection body the splice member is pressed into the connector body, wherein the cutting terminals arranged in the connector body penetrate into the incisions provided in the splice part, thereby penetrating the core insulation of the individual wires crossing the incisions and contacting the individual conductors.

Derartig aufgebaute Kabelanschluss- oder -verbindungseinrichtungen, welche grundsätzlich bereits aus DE 198 36 662 C2 bekannt sind, haben sich in der Praxis seit über fünfzehn Jahren außerordentlich bewährt und werden insbesondere von der Anmelderin unter der Produktbezeichnung QUICKON® in verschiedenen Ausführungsformen umfangreich vertrieben (vgl. Prospekt "PLUSCON 2011" Seiten 92 und 93, der Phoenix Contact GmbH & Co. KG ).Such constructed cable connection or connection devices, which basically already made DE 198 36 662 C2 are known, have proven in practice for over fifteen years extremely well and in particular by the applicant under the product name QUICKON® in various embodiments extensively distributed (see. Prospectus "PLUSCON 2011" pages 92 and 93, Phoenix Contact GmbH & Co. KG ).

Auch aus der DE 10 2012 103 708 B3 ist ein ähnliches Kabelanschlussbauteil als Teil eines Steckverbinders bekannt. Das Anschlussbauteil besteht aus einem inneren Klemmteil, entlang dessen Mantelfläche mehrere Ausnehmungen für die einzelnen Adern angeordnet sind, in denen Klemmrippen ausgebildet sind, die die Adern in den Ausnehmungen festklemmen. Außerdem weist das Anschlussbauteil eine Positionierungshülse auf, die auf das Klemmteil aufschiebbar ist. Die Positionierungshülse weist radial nach innen gerichtete, keilförmige Stege auf, die die einzelnen Leiter in eine S-fömrige Bahn zwingen. Beim Zusammenstecken des Anschlussbauteils mit einem Kontaktierungsteil durchdringen in dem Kontaktierungsteil angeordnete Schneidklemmen die Isolierung der einzelnen Adern und kontaktieren diese elektrisch.Also from the DE 10 2012 103 708 B3 a similar cable connection component is known as part of a connector. The connection component consists of an inner clamping part, along the lateral surface of which a plurality of recesses for the individual wires are arranged, in which clamping ribs are formed, which clamp the wires in the recesses. In addition, the connection component has a positioning sleeve which can be pushed onto the clamping part. The positioning sleeve has radially inwardly directed, wedge-shaped webs which force the individual conductors into an S-shaped path. When mating the connection component with a contacting part, cutting terminals arranged in the contacting part penetrate the insulation of the individual conductors and contact them electrically.

In der industriellen Prozess- und Messtechnik wird häufig eine hohe Störfestigkeit gefordert. Sie ist in der Mess-, Steuer- und Regelungstechnik ein entscheidender Faktor für die Verfügbarkeit industrieller Anlagen. Beim Aufbau von störungsarmen System werden dabei zunehmend geschirmte Kabel verwendet, um kapazitive und induktive elektromagnetische Einkopplungen in das Kabel zu verhindern. Dabei ist das eine Ende des geschirmten Kabels häufig über einen Steckverbinder bzw. eine Kabelanschlusseinrichtung mit einem elektrischen Gerät, beispielsweise einer Sensor-Aktor-Box, und das andere Ende mit dem Versorgungsanschluss, beispielsweise über eine Reihenklemme, verbunden. Die Kontaktierung der Schirmung des Kabels erfolgt auf der Geräteseite zumeist über die metallische Hülse des Steckverbinders bzw. des Anschlusskörpers, über die die Schirmung mit dem metallischen Gehäuse des elektrischen Geräts verbunden wird.In industrial process and measurement technology, high immunity to interference is often required. It is a decisive factor in the availability of industrial plants in measurement and control technology. In the construction of low-noise system increasingly shielded cables are used to prevent capacitive and inductive electromagnetic couplings in the cable. In this case, one end of the shielded cable is often connected via a plug connector or a cable connection device to an electrical device, for example a sensor-actuator box, and the other end to the supply connection, for example via a terminal block. The contacting of the shield of the cable is done on the side of the device mostly via the metallic sleeve of the connector or the Connecting body, via which the shield is connected to the metallic housing of the electrical device.

Die DE 37 34 667 C1 offenbart einen Kabelendstecker zum Aufstecken auf ein Koaxialkabel, der zusammen mit dem abgesetzten Ende des Koaxialkabels in eine Steckvorrichtung einer Anschlussvorrichtung eingesteckt wird. Der Kabelendstecker weist zwei Steckerhülsenteile aus Kunststoff auf, zwischen denen eine ringförmige Kontakthülse angeordnet ist. Die Kontakthülse weist eine Ringscheibe als Mittelabschnitt und beidseits des Mittelabschnitts angeodnete, einzelne Kontaktzungen auf. Die äußeren Kontaktzungen dienen zur Kontaktierung der leitenden Innenwand der Steckvorrichtung und die inneren Kontaktzungen zur Kontaktierung des Außenleiters des Koaxialkabels.The DE 37 34 667 C1 discloses a cable end plug for mounting on a coaxial cable, which is inserted together with the remote end of the coaxial cable in a plug device of a connection device. The cable end plug has two plug sleeve parts made of plastic, between which an annular contact sleeve is arranged. The contact sleeve has an annular disk as a central portion and on both sides of the central portion angeodnete, individual contact tongues. The outer contact tongues serve for contacting the conductive inner wall of the plug-in device and the inner contact tongues for contacting the outer conductor of the coaxial cable.

Aus der Praxis sind verschiedene Möglichkeiten bekannt, wie die elektrisch leitende Verbindung zwischen der Schirmung des Kabels und der metallischen Steckerhülse eines Steckverbinders, die dann als Schirmungshülse fungiert, hergestellt werden kann. Dabei kann die Schirmung entweder direkt oder über ein zusätzliches Schirmungselement mit der metallischen Steckerhülse verbunden werden. Aus der Praxis sind Steckverbinder bekannt, bei denen die Schirmung, die häufig als Schirmgeflecht ausgebildet ist, direkt mit der Steckerhülse verlötet wird. Diese Art der Verbindung der Schirmung mit der Steckerhülse erfordert jedoch einen relativ hohen Montageaufwand, wobei darüber hinaus der Lötprozess aufgrund der relativ hohen Masse der Steckerhülse relativ schwierig ist.From practice, various ways are known as the electrically conductive connection between the shield of the cable and the metallic plug sleeve of a connector, which then acts as Schirmungshülse, can be produced. In this case, the shield can be connected either directly or via an additional shielding element with the metallic plug sleeve. From practice connectors are known in which the shield, which is often designed as a shield braid, is soldered directly to the connector sleeve. However, this type of connection of the shield with the plug sleeve requires a relatively high installation cost, and moreover, the soldering process is relatively difficult due to the relatively high mass of the plug sleeve.

Bei einer alternativen Ausgestaltung der direkten Verbindung der Schirmung mit der Steckerhülse wird ein Teil des Kabelmantels am freien Ende des Kabels entfernt und die Schirmung über den angrenzenden Kabelmantel zurückgeschoben, bevor das so vorbereitete Kabel in die Steckerhülse eingeführt wird. Anschließend wird die Steckerhülse in dem Bereich, in dem die Schirmung über den Kabelmantel zurückgeschoben worden ist, soweit deformiert, dass die Schirmung zwischen dem Kabelmantel und der Steckerhülse eingeklemmt wird. Eine derartige direkte Verbindung der Schirmung des Kabels mit einer metallischen Steckerhülse ist bei der zuvor beschriebenen Kabelanschlusseinrichtung bzw. dem beschriebenen Kabelanschlussbauteil nicht ohne Weiteres möglich, weil das Kabel innerhalb des Kabelanschlussbauteils von dem aus isolierendem Material bestehenden Spleißteil umgeben ist.In an alternative embodiment of the direct connection of the shield to the connector sleeve, a portion of the cable jacket is removed at the free end of the cable and the shield is pushed back over the adjacent cable jacket before the cable thus prepared is inserted into the connector sleeve. Subsequently, the plug sleeve in the region in which the shield has been pushed back over the cable sheath, deformed so far that the shield between the cable sheath and the connector sleeve is clamped. Such a direct connection of the shield of the cable with a metallic plug sleeve is not without in the previously described cable connection device or the described cable connection component Further possible, because the cable is surrounded within the cable connection component of the existing of insulating material splice part.

Die DE 20 2008 004 892 U1 schlägt daher die Verwendung eines topfförmigen, einen Boden und einen abgewinkelten Kragen aufweisenden Schirmübergabeelements vor, dass auf der dem anzuschließenden Kabel zugewandten Seite des Spleißteils aufgesteckt wird. Zur elektrischen Verbindung der Schirmung des Kabels mit der metallischen Steckerhülse des Geräteanschlussteils wird die freigelegte Schirmung des Kabels derart nach außen über den Kragen des Schirmungselements geführt, dass die Schirmung beim Aufschrauben der Überwurfmutter auf das Außengewinde der Steckerhülse diese elektrisch leitend kontaktiert. Nachteilig ist hierbei, dass zur Gewährleistung einer sicheren Weiterleitung der Abschirmwirkung der Schirmung diese vor dem Anschließen der Adern des Kabels von Hand über den Kragen des Schirmübergabeelements gelegt werden muss.The DE 20 2008 004 892 U1 Therefore proposes the use of a cup-shaped, a bottom and an angled collar having screen transfer element that is plugged onto the cable to be connected facing side of the splice. For electrical connection of the shielding of the cable with the metallic plug sleeve of the device connection part, the exposed shielding of the cable is guided outwardly over the collar of the shielding element such that the shielding contacts the external thread of the plug sleeve when the screwed connection is screwed onto it in an electrically conductive manner. The disadvantage here is that to ensure safe forwarding of the shielding the shielding must be placed before connecting the wires of the cable by hand on the collar of the screen transfer element.

Aus der DE 10 2010 017 265 B4 ist ein eingangs beschriebenes Kabelanschlussbauteil bekannt, bei dem innerhalb des Spleißteils, dort als Führungseinrichtung bezeichnet, ein Schirmungselement angeordnet ist. Das Schirmungselement ist als trichterförmige Fangeinrichtung ausgebildet, die ein ringförmiges Basisteil sowie vier in Richtung der Längsachse des Spleißteils bzw. des Kabelanschlussbauteils nach innen abgebogene Federelemente aufweist. Außerdem ist eines der Federelemente mit einem sich in Längsrichtung des Kabelanschlussbauteils erstreckenden Leitungselement verbunden, das ebenso wie die Adern des anzuschließenden Kabels in das Spleißteil eingeführt wird. Beim Aufschrauben der Überwurfmutter auf das Außengewinde des Anschlusskörpers wird dann das Leitungselement wie die Adern des Kabels von einer im Anschlusskörper angeordneten Schneidklemme kontaktiert. Bei der aus der DE 10 2010 017 265 B4 bekannten Kabelanschlusseinrichtung erfolgt die elektrisch leitende Verbindung der Schirmung des Kabels über das Schirmungselement und das Leitungselement somit nur mit einem der im Anschlusskörper angeordneten Kontakte.From the DE 10 2010 017 265 B4 a cable connection component described above is known in which a shielding element is arranged inside the splice part, where it is referred to as a guide device. The shielding element is designed as a funnel-shaped catching device, which has an annular base part and four in the direction of the longitudinal axis of the splice part or the cable connection component inwardly bent spring elements. In addition, one of the spring elements is connected to a line element extending in the longitudinal direction of the cable connection component, which, like the wires of the cable to be connected, is inserted into the splicing part. When screwing the union nut on the external thread of the connector body, the line element as the cores of the cable is then contacted by an arranged in the connection body insulation displacement terminal. At the time of the DE 10 2010 017 265 B4 Known cable connection device, the electrically conductive connection of the shielding of the cable via the shielding element and the line element thus takes place only with one of the contacts arranged in the connection body.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kabelanschlussbauteil bzw. eine Kabelanschlusseinrichtung und eine Kabelverbindungsrichtung zur Verfügung zu stellen, die ein einfaches Anschließen eines geschirmten mehradrigen Kabels ermöglicht. Auf eine besondere Vorbereitung der Schirmung des Kabels soll dabei möglichst verzichtet werden.The invention is therefore based on the object to provide a cable connection component or a cable connection device and a cable connection direction, which is a simple connection of a shielded multicore Cable allows. On a special preparation of the shielding of the cable should be omitted as possible.

Diese Aufgabe bei dem eingangs beschriebenen Kabelanschlussbauteil mit den Merkmalen des Patentanspruchs 1 dadurch gelöst, dass das Spleißteil ein Kabelaufnahmeteil und ein Adernführungsteil aufweist, wobei das Kabelaufnahmeteil auf der dem Adernführungsteil zugewandten Seite mehrere Rastarme und das Adernführungsteil auf der dem Kabelaufnahmeteil zugewandten Seite mehrere zu den Rastarmen korrespondierende, nach innen ragende Rasthaken aufweist. Außerdem weist das Schirmungselement einen ringförmigen Mittelabschnitt, mehrere vom Mittelabschnitt in Richtung der dem Adernführungsteil zugewandten Seite sich erstreckende innere Federarme und mehrere vom Mittelabschnitt in Richtung der dem Adernführungsteil abgewandten Seite sich erstreckende äußere Federarme auf. Die inneren Federarme sind dabei derart in Richtung der Längsachse des Kabelanschlussbauteils nach innen abgebogen, dass ihre Enden die Schirmung eines angeschlossenen Kabels kontaktieren, während die äußeren Federarme derart von der Längsachse des Kabelanschlussbauteils weg nach außen abgebogen sind, dass sich die äußeren Federarme zwischen dem Kabelaufnahmeteil und dem Adernführungsteil erstrecken, wobei die Enden der äußeren Federarme aus dem Spleißteil herausragen.This object is achieved in the cable connection component described above with the features of claim 1, characterized in that the splice part on the wire guide part facing side a plurality of latching arms and the wire guide part on the cable receiving part facing side more to the latching arms Has corresponding, inwardly projecting latching hooks. In addition, the shielding element has an annular central portion, a plurality of extending from the central portion in the direction of the wire guide member side facing inner spring arms and a plurality of the central portion in the direction of the wire guide part remote from the side extending outer spring arms. The inner spring arms are bent inwardly in the direction of the longitudinal axis of the cable connection component in such a way that their ends contact the shielding of a connected cable, while the outer spring arms are bent away from the longitudinal axis of the cable connection component in such a way that the outer spring arms between the cable receiving part and the wire guide member, wherein the ends of the outer spring arms protrude from the splice member.

Wie bei dem aus der DE 10 2010 017 265 B4 bekannten Kabelanschlussbauteil dienen auch bei dem erfindungsgemäßen Kabelanschlussbauteil die inneren Federarme der elektrischen Kontaktierung der Schirmung des Kabels. Die elektrische Weiterleitung erfolgt bei dem erfindungsgemäßen Kabelanschlussbauteil jedoch nicht über ein einzelnes Leitungselement zu einem einzelnen Kontakt eines Geräteanschlussbauteils, sondern über die äußeren Federarme zu dem als Schirmungshülse fungierenden metallischen Anschlusskörper eines Geräteanschlussbauteils bzw. eines Kabelverbindungsbauteils.Like the one from the DE 10 2010 017 265 B4 Known cable connection component also serve in the cable connection component according to the invention, the inner spring arms of the electrical contacting of the shielding of the cable. However, in the case of the cable connection component according to the invention, electrical transmission does not take place via a single line element to a single contact of a device connection component, but via the outer spring arms to the metallic connection body of a device connection component or a cable connection component which functions as the shielding sleeve.

Dadurch, dass das Spleißteil zweiteilig ausgebildet ist, nämlich aus einem Kabelaufnahmeteil und einem Adernführungsteil besteht, ist auf einfache Art und Weise die Möglichkeit geschaffen worden, die im Inneren des Spleißteils angeordnete Schirmung des Kabels über das Schirmungselement am Außenumfang des Spleißteils zu kontaktieren. Dadurch, dass das Schirmungselement mehrere äußere Federarme aufweist, erfolgt eine Anbindung der Schirmung an den metallischen Anschlusskörper an mehreren, über den Umfang verteilten Punkten, was für eine gute Schirmanbindung wünschenswert ist. Aufgrund der federnden Eigenschaft der inneren Federarme erfolgt dabei die Kontaktierung der Schirmung des Kabels automatisch beim Einführen des Kabels in das Kabelanschlussbauteil bzw. in das Kabelaufnahmeteil des Spleißteils, so dass eine besondere, zusätzliche Vorbereitung der Schirmung nicht erforderlich ist. Der Anschluss des geschirmten Kabels erfolgt vielmehr so, wie dies der Monteur vom Anschluss eines ungeschirmten Kabels an ein aus dem Stand der Technik bekanntes Kabelanschlussbauteil kennt.Characterized in that the splice part is formed in two parts, namely consists of a cable receiving part and a wire guide part, the possibility has been created in a simple manner to contact the arranged inside the splice part shielding of the cable via the shielding element on the outer circumference of the splice. Due to the fact that the shielding element has a plurality of outer spring arms, a connection of the shield to the metallic connector body at several distributed over the circumference points, which is desirable for a good shield connection. Due to the resilient property of the inner spring arms, the contacting of the shielding of the cable takes place automatically upon insertion of the cable into the cable connection component or into the cable receiving part of the splice part, so that a special, additional preparation of the shield is not required. The connection of the shielded cable is rather as the installer knows from the connection of an unshielded cable to a known from the prior art cable connection component.

Gemäß einer bevorzugten Ausgestaltung des Kabelanschlussbauteils sind die Rastarme des Kabelaufnahmeteils konzentrisch zur Längsachse des Kabelanschlussbauteils angeordnet, wobei im montierten Zustand von Kabelaufnahmeteil und Adernführungsteil ein dem Kabelanschlussbauteil zugewandter hülsenförmiger Bereich des Adernführungsteils die Rastarme umgibt. Der hülsenförmige Bereich des Adernführungsteils wird somit zur Verbindung mit dem Kabelaufnahmeteil einfach auf die Rastarme aufgesteckt, wobei die Rastarme mit den im Inneren des hülsenförmigen Bereichs angeordneten, korrespondierenden Rasthaken verrasten, so dass das Kabelaufnahmeteil und das Adernführungsteil sicher miteinander verbunden sind. Dadurch, dass der hülsenförmige Bereich des Adernführungsteils die Rastarme des Kabelaufnahmeteils im montierten Zustand umgibt, wird der Verbindungsbereich zwischen dem Kabelaufnahmeteil und dem Adernführungsteil mechanisch geschützt und darüber hinaus die Abdichtung der innerhalb der Rastarme des Kabelaufnahmeteils verlaufenden Adern des Kabels verbessert.According to a preferred embodiment of the cable connection component, the latching arms of the cable receiving part are arranged concentrically to the longitudinal axis of the cable connection component, wherein in the assembled state of cable receiving part and wire guide part facing the cable connection component sleeve-shaped portion of the wire guide part surrounding the latching arms. The sleeve-shaped region of the wire guide part is thus simply plugged onto the latching arms for connection to the cable receiving part, wherein the latching arms engage with the corresponding latching hooks arranged in the interior of the sleeve-shaped region, so that the cable receiving part and the wire guide part are securely connected to one another. Characterized in that the sleeve-shaped portion of the wire guide part surrounds the latching arms of the cable receiving part in the assembled state, the connection area between the cable receiving part and the wire guide part is mechanically protected and beyond the sealing of extending within the latching arms of the cable receiving part wires of the cable.

Wie zuvor ausgeführt worden ist, ist durch die zweiteilige Ausbildung des Spleißteils die Möglichkeit geschaffen worden, über das Schirmungselement die im Inneren des Spleißteils angeordnete Schirmung des anzuschließenden Kabels außerhalb des Spleißteils, nämlich durch den metallischen Anschlusskörper zu kontaktieren. Hierzu ist das Schirmungselement zwischen dem Kabelaufnahmeteil und dem Adernführungsteil angeordnet, wobei gemäß einer bevorzugten Ausgestaltung der Erfindung der ringförmige Mittelabschnitt des Schirmungselements, der die inneren Federarme mit den äußeren Federarmen verbindet, von den Rastarmen des Kabelaufnahmeteils umgeben ist, d.h. der ringförmige Mittelabschnitt ist innerhalb des Kabelaufnahmeteils angeordnet. Die äußeren Federarme des Schirmungselements erstrecken sich dabei durch die einzelnen Freiräume zwischen den Rastarmen des Kabelaufnahmeteils. Der ringförmige Mittelabschnitt und die Rastarme des Kabelaufnahmeteils sind dadurch beim Verrasten von Kabelaufnahmeteil und Adernführungsteil durch die Rastarme des Kabelaufnahmeteils vor Beschädigungen geschützt. Vorzugsweise sind dazu die inneren Federarme des Schirmungselements korrespondierend zu den Rastarmen des Kabelaufnahmeteils angeordnet, d. h. die inneren Federarme und die Rastarme weisen im montierten Zustand dieselbe Winkelposition auf.As has been stated above, the two-part design of the splice part has made it possible to contact via the shielding element the shielding of the cable to be connected outside the splicing part, namely the metallic connecting body, arranged in the interior of the splicing part. For this purpose, the shielding element between the cable receiving part and the wire guide part is arranged, wherein according to a preferred embodiment of the invention, the annular central portion of the Schirmungselements, which connects the inner spring arms with the outer spring arms, is surrounded by the latching arms of the cable receiving part, ie the annular central portion is disposed within the cable receiving portion. The outer spring arms of the Schirmungselements extend through the individual free spaces between the latching arms of the cable receiving part. The annular central portion and the latching arms of the cable receiving part are thereby protected during the locking of cable receiving part and wire guide part by the locking arms of the cable receiving part from damage. For this purpose, the inner spring arms of the shielding element are preferably arranged corresponding to the latching arms of the cable receiving part, ie the inner spring arms and the latching arms have the same angular position in the mounted state.

Gemäß einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kabelanschlussbauteils sind außerdem die inneren Federarme und die äußeren Federarme gleichmäßig verteilt am Umfang des Mittelabschnitts angeordnet. Hierdurch wird sowohl eine gute elektrische Anbindung der Schirmung als auch eine einfache Herstellung des Schirmungselements, bei dem es sich vorzugsweise um ein Stanz-Biegeteil handelt, ermöglicht. Wenn, wie zuvor beschrieben, die inneren Federelemente korrespondierend zu den Rastarmen angeordnet sind, so sind die äußeren Federarme versetzt zu den inneren Federarmen angeordnet, da sich die äußeren Federarme durch die Freiräume zwischen den Rastarmen hindurch erstrecken.According to a further advantageous embodiment of the cable connection component according to the invention also the inner spring arms and the outer spring arms are arranged evenly distributed on the circumference of the central portion. As a result, both a good electrical connection of the shield and a simple production of the shielding element, which is preferably a stamped and bent part, made possible. If, as described above, the inner spring elements are arranged corresponding to the latching arms, the outer spring arms are arranged offset to the inner spring arms, since the outer spring arms extend through the spaces between the latching arms.

Neben dem zuvor beschriebenen Kabelanschlussbauteil betrifft die Erfindung auch noch eine Kabelanschlusseinrichtung zum elektrisch leitenden Anschließen eines geschirmten mehradrigen Kabels an ein elektrisches Gerät. Bei dem elektrischen Gerät kann es sich beispielsweise um eine Sensor-/Aktor-Box handeln. Unabhängig davon ist hier der Begriff "elektrisches Gerät" jedoch ganz allgemein zu verstehen, d. h. unter dem Begriff "elektrisches Gerät" sollen auch andere elektrische Bauteile, Einrichtungen und Vorrichtungen fallen.In addition to the cable connection component described above, the invention also relates to a cable connection device for the electrically conductive connection of a shielded multicore cable to an electrical device. The electrical device may be, for example, a sensor / actuator box. Regardless of this, however, the term "electrical device" is to be understood here in a general way, that is to say, "electrical device". H. The term "electrical device" is intended to include other electrical components, devices and devices.

Eine derartige Kabelanschlusseinrichtung weist neben dem zuvor beschriebenen Kabelanschlussbauteil noch ein Geräteanschlussbauteil auf, das einen metallischen Anschlusskörper mit einem zum Innengewinde der Überwurfmutter korrespondierenden Außengewinde aufweist. Außerdem sind in dem Anschlusskörper mehrere Schneidklemmen und mit den einzelnen Schneidklemmen verbundene Anschlusselemente vorgesehen, wobei die Schneidklemmen auf der dem Kabelanschlussbauteil zugewandten Seite und die Anschlusselemente auf der dem Kabelanschlussbauteil abgewandten Seite angeordnet sind. Häufig handelt es sich hierbei um einstückig ausgebildete Metallteile, die auf einer Seite als Schneidklemmen und auf der anderen Seite als Anschlusselemente ausgebildet sind. Die Anschlusselemente können vorzugsweise als Stift- oder Buchsenkontakte ausgebildet sein.Such a cable connection device has, in addition to the previously described cable connection component, a device connection component which has a metallic connection body with an external thread corresponding to the internal thread of the union nut. In addition, a plurality of insulation displacement terminals and connection elements connected to the individual insulation displacement terminals are provided in the connection body, wherein the insulation displacement terminals are arranged on the side facing the cable connection component side and the connection elements on the side facing away from the cable connection component side. Often these are integrally formed metal parts which are formed on one side as insulation displacement terminals and on the other side as connection elements. The connection elements may preferably be designed as pin or socket contacts.

Darüber hinaus betrifft die vorliegende Erfindung auch eine Kabelverbindungseinrichtung zum elektrisch leitenden Verbinden von zwei geschirmten mehradrigen Kabeln. Eine derartige Kabelverbindungseinrichtung, die häufig auch als Leitungsverbinder bezeichnet wird, weist neben dem erfindungsgemäßen Kabelanschlussbauteil noch ein Kabelverbindungsbauteil auf. Das Kabelverbindungsbauteil weist einen Anschlusskörper mit einem zum Innengewinde der Überwurfmutter korrespondierenden Außengewinde und mehrere im Anschlusskörper angeordnete Schneidklemmen und Anschlusselemente auf. Ebenso wie bei dem Geräteanschlussbauteil sind auch bei dem Kabelverbindungsbauteil die Schneidklemmen auf der dem Kabelanschlussbauteil zugewandten Seite und die Anschlusselemente auf der gegenüberliegenden Seite angeordnet, wobei die Schneidklemmen und die Anschlusselemente wiederum elektrische leitend miteinander verbunden sind. Für die Anschlusselemente des Kabelverbindungsbauteils, die zum Anschließen der Adern des zweiten Kabels dienen, können grundsätzlich die dem Fachmann bekannten Anschlusstechniken, beispielsweise Schraubanschluss oder Federkraftklemmanschluss, verwendet werden. Vorzugsweise sind jedoch auch die Anschlusselemente des Kabelverbindungsbauteils als Schneidklemmen ausgebildet, so dass in dem Anschlusskörper des Kabelverbindungsbauteils mehrere Metallteile angeordnet sind, die auf beiden Seiten als Schneidklemmen ausgebildet sind. Der Anschlusskörper weist dann ein zweites Außengewinde auf, auf dem die Überwurfmutter eines zweiten Kabelanschlussbauteils aufgeschraubt und damit ein Spleißteil in den Anschlusskörper eingeschoben werden kann.Moreover, the present invention also relates to a cable connection device for the electrically conductive connection of two shielded multicore cables. Such a cable connecting device, which is often referred to as a cable connector, in addition to the cable connection component according to the invention still has a cable connection component. The cable connection component has a connection body with an external thread corresponding to the internal thread of the union nut and a plurality of insulation displacement terminals and connection elements arranged in the connection body. As in the case of the device connection component, the insulation displacement terminals on the side facing the cable connection component and the connection elements on the opposite side are also arranged in the cable connection component, wherein the insulation displacement terminals and the connection elements are in turn electrically conductively connected to one another. For the connection elements of the cable connection component, which serve to connect the wires of the second cable, basically the connection techniques known to the person skilled in the art, for example screw connection or spring terminal connection, can be used. Preferably, however, the connection elements of the cable connection component are formed as insulation displacement terminals, so that in the connection body of the cable connection component a plurality of metal parts are arranged, which are formed on both sides as insulation displacement terminals. The connection body then has a second external thread, onto which the union nut of a second cable connection component can be screwed and thus a splice part can be inserted into the connection body.

Die Montage des Spleißteils mit dem Schirmungselement bzw. des Schirmungselements in dem Spleißteil erfolgt erfindungsgemäß gemäß den Merkmalen des Patentanspruchs 9. Das Verfahren weist dabei folgende wesentliche Schritte auf:

  • Aufweiten der Rastarme des Kabelaufnahmeteils und Einführen des Schirmungselements zwischen die Rastarme des Kabelaufnahmeteils, wobei sich die äußeren Federarme des Schirmungselements durch die Freiräume zwischen den Rastarmen erstrecken;
  • Aufstecken des Adernführungsteils auf das Kabelaufnahmeteil, so dass die Rastarme am Kabelaufnahmeteil mit den Rasthaken am Adernführungsteil verrasten.
According to the invention, the splice part with the shielding element or the shielding element is mounted in the splice part according to the features of claim 9. The method has the following essential steps:
  • Widening the latching arms of the cable receiving part and inserting the shielding element between the latching arms of the cable receiving part, wherein the outer spring arms of the Schirmungselements extend through the free spaces between the latching arms;
  • Attach the wire guide part on the cable receiving part, so that the latching arms engage the cable receiving part with the latching hooks on the wire guide part.

Bei dem erfindungsgemäßen Verfahren erfolgt dabei das Aufweiten der Rastarme des Kabelaufnahmeteils vorzugsweise mit Hilfe eines Domes, der von der dem Adernführungsteil abgewandten Seite in das Kabelaufnahmeteil eingesteckt wird. Ist das Schirmungselement zwischen die Rastarme des Kabelaufnahmeteils eingeführt, so wird der Dorn aus dem Kabelaufnahmeteil herausgezogen, so dass die Rastarme zurückfedern und dadurch das Schirmungselement in seiner Endposition radial fixieren. Durch das Aufstecken des Adernführungsteils auf das Kabelaufnahmeteil erfolgt sowohl die rastende Verbindung zwischen dem Adernführungsteil und dem Kabelaufnahmeteil, als auch die axiale Fixierung des Schirmungselement, da sich die freien Enden der äußeren Federarme zwischen der dem Kabelaufnahmeteil zugewandten Stirnseite des Adernführungsteils und einem entsprechend ausgebildeten Anschlagbund am Kabelaufnahmeteil nach außen, d. h. aus dem Spleißteil heraus, erstrecken.In the method according to the invention, the expansion of the latching arms of the cable receiving part is preferably carried out by means of a dome, which is inserted from the side facing away from the wire guide part in the cable receiving part. If the shielding element is inserted between the latching arms of the cable receiving part, then the mandrel is pulled out of the cable receiving part, so that the latching arms spring back and thereby radially fix the shielding element in its end position. By attaching the wire guide part on the cable receiving part takes place both the latching connection between the wire guide part and the cable receiving part, as well as the axial fixation of the Schirmungselement, as the free ends of the outer spring arms between the cable receiving part facing end side of the wire guide part and a trained stop collar on Cable receiving part to the outside, d. H. out of the splice part, extend.

Im Einzelnen gibt es nun eine Vielzahl von Möglichkeiten, das erfindungsgemäße Kabelanschlussbauteil sowie die Kabelanschlusseinrichtung und die Kabelverbindungseinrichtung auszugestalten und weiterzubilden.

Die Fig. 1 zeigt ein erfindungsgemäßes Kabelanschlussbauteil 1 zum Anschluss eines in den Fig. 2 und 7 dargestellten geschirmten mehradrigen Kabels 2. Das Kabel 2 weist mehrere Adern 21, eine alle Adern 21 zusammen umgebende Schirmung 22 und einen die Schirmung 22 umgebenden Kabelmantel 23 auf. Zu dem Kabelanschlussbauteil 1 gehören insbesondere eine ein Innengewinde 3 aufweisende Überwurfmutter 4, ein mehrere Einschnitte 5 aufweisendes Spleißteil 6 aus isolierendem Material sowie ein Schirmungselement 7. Wird die Überwurfmutter 4 mit ihrem Innengewinde 3 auf einen ein korrespondierendes Außengewinde 8 aufweisenden metallischen Anschlusskörper 9 aufgeschraubt, so wird das Spleißteil 6 in den zylinderförmigen Anschlusskörper 9 hineingedrückt, wobei die im Anschlusskörper 9 angeordneten Schneidklemmen 10 in die Einschnitte 5 im Spleißteil 6 eintauchen und die Aderisolation der einzelnen Adern 21, die die Einschnitte 5 kreuzen, durchdringen und die einzelnen Adern 21 kontaktieren.The Fig. 1 shows a cable connection component 1 according to the invention for connecting a in the Fig. 2 and 7 The cable 2 has a plurality of wires 21, a shielding 22 surrounding all cores 21 together and a cable jacket 23 surrounding the shielding 22. To the cable connection component 1 in particular include an internal thread 3 having a union nut 4, a plurality of incisions 5 having splice 6 of insulating material and a shielding element 7. If the union nut 4 is screwed with its internal thread 3 on a corresponding external thread 8 having metallic terminal body 9, so the splice member 6 is pressed into the cylindrical connector body 9, wherein the cutting terminals 10 arranged in the connector body 9 dive into the recesses 5 in the splice member 6 and penetrate the wire insulation of the individual wires 21, which intersect the incisions 5, and contact the individual wires 21.

Wie aus der Explosionsdarstellung gemäß Fig. 1 erkennbar ist, besteht das separat in Fig. 3 nochmals dargestellte Spleißteil 6 aus einem Kabelaufnahmeteil 11 und einem mit dem Kabelaufnahmeteil 11 verrastbaren hülsenförmigen Adernführungsteil 12. Dabei weist das Kabelaufnahmeteil 11 mehrere federnde Rastarme 13 und das Adernführungsteil 12 zu den Rastarmen 13 korrespondierende, nach innen, d. h. in Richtung der Längsachse des Adernführungsteils 12 weisende Rasthaken 14 auf.As shown in the exploded view according to Fig. 1 is recognizable, this consists separately in Fig. 3 again splice part 6 shown from a cable receiving part 11 and a latchable with the cable receiving part 11 sleeve-shaped wire guide part 12. In this case, the cable receiving part 11 has a plurality of resilient latching arms 13 and the wire guide part 12 to the latching arms 13, inwardly, ie in the direction of the longitudinal axis of the wire guide part 12 facing latching hooks 14.

Das in Fig. 1 und in Fig. 6 nochmals separat dargestellte Schirmungselement 7 besteht aus einem etwa ringförmigen Mittelabschnitt 15, mehreren vom Mittelabschnitt 15 in Richtung der dem Adernführungsteil 12 zugewandten Seite sich erstreckenden inneren Federarmen 16 und mehreren vom Mittelabschnitt 15 in Richtung der dem Adernführungsteil 12 abgewandten Seite sich erstreckenden äußeren Federarmen 17. Insbesondere aus Fig. 2 ist dabei erkennbar, dass die inneren Federarme 16 derart in Richtung der Längsachse des Kabelanschlussbauteils 1 nach innen abgebogen sind, dass die Enden der inneren Federarme die Schirmung 22 eines angeschlossenen Kabels 2 kontaktieren. Im Unterschied dazu sind die äußeren Federarme 17 vom ringförmigen Mittelabschnitt 15 nach außen abgebogen, d. h. von der Längsachse des Kabelanschlussbauteils 1 weggebogen. Im montierten Zustand des Spleißteils 6 erstrecken sich die äußeren Federarme 17 zwischen dem Kabelaufnahmeteil 11 und dem Adernführungsteil 12 hindurch, sodass die Enden 18 der äußeren Federarme 17 nach außen aus dem Spleißteil 6 herausragen.This in Fig. 1 and in Fig. 6 again separately shown shielding element 7 consists of an approximately annular central portion 15, a plurality of the central portion 15 in the direction of the wire guide member 12 side facing extending inner spring arms 16 and more from the central portion 15 in the direction of the wire guide member 12 side facing outer spring arms 17. In particular out Fig. 2 It can be seen that the inner spring arms 16 are bent inwardly in the direction of the longitudinal axis of the cable connection component 1 in such a way that the ends of the inner spring arms contact the shield 22 of a connected cable 2. In contrast, the outer spring arms 17 are bent from the annular central portion 15 to the outside, ie bent away from the longitudinal axis of the cable connection component 1. In the assembled state of the splice part 6, the outer spring arms 17 extend between the cable receiving part 11 and the wire guide part 12, so that the ends 18 of the outer spring arms 17 protrude outwardly from the splice part 6.

Wie aus Fig. 2 und 3 ersichtlich ist, sind die konzentrisch zur Längsachse des Kabelanschlussbauteils 1 angeordneten Rastarme 13 im montierten Zustand von Kabelaufnahmeteil 11 und Adernführungsteils 12 von einem dem Kabelaufnahmeteil 11 zugewandten hülsenförmigen Bereich 19 des Adernführungsteils 12 umgeben. Dadurch, dass der hülsenförmige Bereich 19 des Adernführungsteils 12 die Rastarme 13 des Kabelaufnahmeteils 11 umschließt, wird ein ungewolltes Lösen der Rastverbindung zwischen dem Kabelaufnahmeteil 11 und dem Adernführungsteil 12 beim Einstecken des Spleißteils 6 in den Anschlusskörper 9 verhindert. Darüber hinaus erfolgt auch eine sichere Abdichtung der innerhalb der Rastarme 13 des Kabelaufnahmeteils 11 verlaufenden Adern 21 des Kabels 2.How out Fig. 2 and 3 it can be seen, the latching arms 13 are arranged concentrically to the longitudinal axis of the cable connection component 1 in the assembled state of the cable receiving part 11 and wire guide part 12 of a sleeve-shaped portion 19 of the wire guide part 12 facing the cable receiving part 11. Characterized in that the sleeve-shaped portion 19 of the wire guide part 12 encloses the latching arms 13 of the cable receiving part 11, an unintentional release of the latching connection between the cable receiving part 11 and the wire guide part 12 during insertion of the splice member 6 is prevented in the connector body 9. In addition, there is also a secure seal of the running within the locking arms 13 of the cable receiving part 11 wires 21 of the cable. 2

Fig. 3 zeigt das Spleißteil 6 im montierten Zustand, wobei der ringförmige Mittelabschnitt 15 des Schirmungselements 7 innerhalb des Kabelaufnahmeteils 11 angeordnet, nämlich von den Rastarmen 13 umgeben ist. Die äußeren Federarme 17 des Schirmungselements 7 erstrecken sich dabei durch die Freiräume 20 zwischen den einzelnen Rastarmen 13. Dabei ist erkennbar, dass sowohl die inneren Federarme 16 als auch die äußeren Federarme 17 gleichmäßig verteilt am Umfang des Mittelabschnitts 15 angeordnet sind, wobei die inneren Federarme 16 jedoch derart versetzt zu den äußeren Federarmen 17 angeordnet sind, dass die inneren Federarme 16 die gleiche Winkelposition wie die Rastarme 13 aufweisen, so dass jeweils ein innerer Federarm 16 von einem korrespondierenden Rastarm 13 abgedeckt ist. Fig. 3 shows the splice member 6 in the assembled state, wherein the annular central portion 15 of the Schirmungselements 7 disposed within the cable receiving part 11, namely surrounded by the latching arms 13. The outer spring arms 17 of the Schirmungselements 7 extend through the spaces 20 between the individual locking arms 13. It can be seen that both the inner spring arms 16 and the outer spring arms 17 are arranged evenly distributed on the circumference of the central portion 15, wherein the inner spring arms 16 are arranged offset to the outer spring arms 17 so that the inner spring arms 16 have the same angular position as the latching arms 13, so that in each case an inner spring arm 16 is covered by a corresponding latching arm 13.

Aus der vergrößerten Darstellung des Schirmungselements 7 gemäß Fig. 6 ist darüber hinaus ersichtlich, dass sich die Breite der inneren Federarme 16 vom Mittelabschnitt 15 zu ihrem Ende hin verringert, wobei die Enden nach außen abgebogen sind, um die Kontaktierung der Schirmung 22 des Kabels 2 zu erleichtern. Die durch die freien Enden der inneren Federarme 16 ausgebildete Öffnung weist einen Durchmesser auf, der etwas kleiner als der Außendurchmesser der Schirmung 22 ist, so dass beim Einschieben eines Kabels 2 durch das Schirmungselement 7 die inneren Federarme 16 etwas ausgelenkt werden. Hierdurch wird eine sichere und gute elektrische Kontaktierung der Schirmung 22 durch die Enden der inneren Federarme 16 sichergestellt.From the enlarged view of the Schirmungselements 7 according to Fig. 6 In addition, it can be seen that the width of the inner spring arms 16 is reduced from the central portion 15 towards its end, the ends being bent outwardly to facilitate the contacting of the shield 22 of the cable 2. The opening formed by the free ends of the inner spring arms 16 has a diameter which is slightly smaller than the outer diameter of the shield 22, so that upon insertion of a cable 2 through the Schirmungselement 7, the inner spring arms 16 are slightly deflected. As a result, a secure and good electrical contacting of the shield 22 is ensured by the ends of the inner spring arms 16.

Während sich die Breite der inneren Federarme 16 zu ihrem Ende hin verringert, vergrößert sich die Breite der äußeren Federarme 17 vom Mittelabschnitt 15 zu ihren Enden 18, wobei die Enden 18 bei dem dargestellten Ausführungsbeispiel etwa V-förmig aufgespreitzt sind. Hierdurch wird erreicht, dass die aus dem Spleißteil 6 nach außen herausragenden Enden 18 der äußeren Federarme 17 den Innenumfang des metallischen Anschlusskörpers 9 an mehreren über den Umfang des Anschlusskörpers 9 verteilten Punkten kontaktiert. Gleichzeitig wird durch die Aufspaltung der Enden 18 der äußeren Federarme 17 deren Elastizität erhöht, was sich ebenfalls positiv auf die elektrische Verbindung zwischen den Enden 18 der äußeren Federarme 17 und der Innenfläche des metallischen Anschlusskörpers 9 auswirkt.As the width of the inner spring arms 16 decreases toward its end, the width of the outer spring arms 17 increases from the central portion 15 to their ends 18, the ends 18 being approximately V-shaped in the illustrated embodiment. In this way, it is achieved that the ends 18 of the outer spring arms 17 projecting outward from the splicing part 6 make contact with the inner circumference of the metallic connecting body 9 at a plurality of points distributed over the circumference of the connecting body 9. At the same time, the splitting of the ends 18 of the outer spring arms 17 increases their elasticity, which likewise has a positive effect on the electrical connection between the ends 18 of the outer spring arms 17 and the inner surface of the metallic connection body 9.

Wie aus Fig. 1 ersichtlich ist, weist das Kabelanschlussbauteil 1 noch eine ringförmige Dichtung 24 auf, die zusammen mit einer Mehrzahl von ringförmig am Kabelaufnahmeteil 11 ausgebildeten Lamellen 25 einen Zugentlastungs- und Dichtungsbereich bildet. Die Lamellen 25 wirken dabei beim Aufschrauben der Überwurfmutter 4 mit einer innenseitig an der Überwurfmutter 4 vorgesehenen Abschrägung nach Art einer PG-Verschraubung zusammen, so dass beim Aufschrauben der Überwurfmutter 4 auf den Anschlusskörper 9 die Lamellen 25 gegen die Dichtung 24 gedrückt werden, wodurch sich eine Abdichtung und gleichzeitig auch eine Zugentlastung eines eingeführten Kabels 2 ergibt.How out Fig. 1 it can be seen, the cable connection component 1 still has an annular seal 24, which forms a Zugentlastungs- and sealing area together with a plurality of annularly formed on the cable receiving part 11 fins 25. The slats 25 cooperate when screwing the union nut 4 with a provided on the inside of the union nut 4 bevel in the manner of a PG gland, so that when screwing the nut 4 on the connector body 9, the fins 25 are pressed against the seal 24, resulting in a seal and at the same time a strain relief of an inserted cable 2.

Die in Fig. 7 dargestellte Kabelanschlusseinrichtung 26 besteht aus einem Kabelanschlussbauteil 1 und einem Geräteanschlussbauteil 27. Das Geräteanschlussbauteil 27 weist einen metallischen Anschlusskörper 9 mit einem Außengewinde 8 sowie eine der Anzahl der anzuschließenden Adern 21 entsprechende Anzahl an Schneidklemmen 10 und mit den Schneidklemmen 10 elektrisch leitend verbundene Anschlusselemente 28 auf. Vorliegend sind die Anschlusselemente 28 als Stiftkontakte ausgebildet, die mit den Schneidklemmen 10 jeweils verlötet oder verschweißt sind. Bei dem in Fig. 7 dargestellten Ausführungsbeispiel der Kabelanschlusseinrichtung 26 ist das Geräteanschlussbauteil 27 als Steckverbinder ausgebildet. Der Anschlusskörper 9 weist auf der dem Kabelanschlussbauteil 1 abgewandten Seite ein zweites Außengewinde 29 auf, das drehbar ist und somit in eine korrespondierende Anschlussdose eingeschraubt werden kann.In the Fig. 7 The cable connection device 26 comprises a cable connection component 1 and a device connection component 27. The device connection component 27 has a metallic connection body 9 with an external thread 8 and a number of insulation displacement terminals 10 corresponding to the number of leads 21 to be connected and connection elements 28 connected in an electrically conductive manner to the insulation displacement terminals 10. In the present case, the connection elements 28 are designed as pin contacts, which are each soldered or welded to the insulation displacement terminals 10. At the in Fig. 7 illustrated embodiment of the cable connection device 26, the device connection component 27 is formed as a connector. The connection body 9 has on the side facing away from the cable connection component 1 a second external thread 29, which is rotatable and thus can be screwed into a corresponding junction box.

Zur Montage des Spleißteils 6 mit dem Schirmungselements 7 werden zunächst die Rastarme 13 des Kabelaufnahmeteils 11 aufgeweitet, so dass das Schirmungselement 7 mit seinem Mittelabschnitt 15 zwischen die Rastarme 13 eingeschoben werden kann. Die äußeren Federarme 17 erstrecken sich dabei durch die Freiräume 20 zwischen den Rastarmen 13, so dass die Enden 18 der äußeren Federarme 17 aus dem Kabelaufnahmeteil 11 seitlich herausragen. Ist das Schirmungselement 7 vollständig zwischen die Rastarme 13 des Kabelaufnahmeteils 11 eingeschoben und die Aufweitung der Rastarme 13 aufgehoben, so wird der Mittelabschnitt 15 zwischen den Rastarmen 13 festgeklemmt, so dass das Schirmungselement 7 radial in seiner Position fixiert ist. Nun wird das Adernführungsteil 12 mit seinem hülsenförmigen Bereich 19 auf das Kabelaufnahmeteil 11 aufgesteckt, wobei die Rasthaken 14 mit den Rastarmen 13 verrasten. Gleichzeitige werden die aus dem Kabelaufnahmeteil 11 seitlich herausragenden Abschnitte der äußeren Federarme 17 von der dem Kabelaufnahmeteil 11 zugewandten Stirnseite des Adernführungsteils 12 gegen einem am Kabelaufnahmeteil 11 ausgebildeten Anschlagbund 30 gedrückt, so dass das Schirmungselement 7 auch axial in seiner Position fixiert ist.For mounting the splice part 6 with the shielding element 7, the latching arms 13 of the cable receiving part 11 are first widened, so that the shielding element 7 can be inserted with its middle section 15 between the latching arms 13. The outer spring arms 17 extend through the free spaces 20 between the latching arms 13, so that the ends 18 of the outer spring arms 17 protrude laterally from the cable receiving part 11. If the shielding element 7 is completely inserted between the latching arms 13 of the cable receiving part 11 and the expansion of the latching arms 13 is canceled, then the middle section 15 is clamped between the latching arms 13, so that the shielding element 7 is fixed radially in its position. Now the wire guide member 12 is fitted with its sleeve-shaped portion 19 on the cable receiving part 11, wherein the latching hooks 14 engage with the latching arms 13. At the same time, the portions of the outer spring arms 17 projecting laterally from the cable receiving part 11 are pressed by the end face of the wire guide part 12 facing the cable receiving part 11 against a stop collar 30 formed on the cable receiving part 11, so that the shielding element 7 is also fixed axially in its position.

Zum elektrisch leitenden Anschließen eines geschirmten mehradrigen Kabels 2 wird zunächst das Kabel 2 in das Kabelanschlussbauteil 1 eingeführt, indem das Ende des Kabels 2 durch die rückwärtige Öffnung in der Überwurfmutter 4 soweit in das Spleißteil 6 eingeschoben wird, dass die einzelnen Aderenden auf der der Überwurfmutter 4 abgewandten Stirnseite aus dem Spleißteil 6 bzw. dem Adernführungsteil 12 herausragen. Anschließend werden die einzelnen Aderenden um etwas 90 ° nach außen umgelegt und in die im Adernführungsteil 12 ausgebildeten Ausnehmungen 31 eingedrückt, die als Rückhaltesperren für die Aderenden dienen (vgl. Fig. 2). Dabei wird beim Einführen des Kabels 2 in das Spleißteil 6 bzw. das Kabelaufnahmeteil 11 die Schirmung 22 des Kabels 2 automatisch von den Enden der inneren Federarme 16 kontaktiert, so dass zur Kontaktierung der Schirmung 22 des Kabels 2 keine zusätzlichen Schritte erforderlich sind.For electrically conductive connection of a shielded multi-core cable 2, the cable 2 is first introduced into the cable connection component 1 by the end of the cable 2 is pushed through the rear opening in the union nut 4 as far into the splice member 6, that the individual wire ends on the union nut 4 facing away from the splice 6 and the wire guide part 12 protrude. Subsequently, the individual wire ends are folded by about 90 ° to the outside and pressed into the formed in the wire guide part 12 recesses 31, which serve as restraint locks for the wire ends (see. Fig. 2 ). In this case, when the cable 2 is inserted into the splicing part 6 or the cable receiving part 11, the shielding 22 of the cable 2 is automatically contacted by the ends of the inner spring arms 16, so that no additional steps are required for contacting the shielding 22 of the cable 2.

Beim Aufschrauben der Überwurfmutter 4 auf das Außengewinde 8 des metallischen Anschlusskörpers 9 wird das Spleißteil 6 in den Anschlusskörper 9 eingeschoben, wobei die im Anschlusskörper 9 angeordneten Schneidklemmen 10 in die im Adernführungsteil 12 ausgebildeten, stirnseitig offenen Einschnitte 5 eintauchen, wodurch eine zuverlässige Kontaktierung der die Einschnitte 5 kreuzenden, nach außen umgelegten Aderenden durch die Schneidklemmen 10 gewährleistet ist. Gleichzeitig kommt es zu einer federnden Anlage der Enden 18 der äußeren Federarme 17 am Innenumfang des metallischen Anschlusskörpers 9, wodurch eine sichere elektrische Verbindung der Schirmung 22 über das Schirmungselement 7 zum metallischen Anschlusskörper 9 gegeben ist.When screwing the union nut 4 on the external thread 8 of the metallic terminal body 9, the splice member 6 is inserted into the connector body 9, wherein the arranged in the connector body 9 insulation displacement plugs 10 in the core guide member 12 formed, dive open at the front incisions 5, whereby a reliable contact of the Incisions 5 crossing, outwardly folded wire ends is ensured by the insulation displacement terminals 10. At the same time there is a resilient abutment of the ends 18 of the outer spring arms 17 on the inner circumference of the metallic connection body 9, whereby a secure electrical connection of the shield 22 is given via the shielding element 7 to the metallic connection body 9.
