Description

Die Erfindung betrifft einen Steckverbinder mit einem Gehäuse und mindestens einem innerhalb des Gehäuses fixierten Kontaktelement, das zur Verbindung mit mindestens einer teilweise von einem Kabelmantel umgebenen Ader eines Kabels ausgebildet ist. Weiterhin betrifft die Erfindung ein System aus einem solchen Steckverbinder und einem Kabel. Insbesondere betrifft die Erfindung ein System aus einem Twisted-Pair-Kabel und einem Steckverbinder mit zwei Kontaktelementen.The invention relates to a connector having a housing and at least one fixed inside the housing contact element, which is designed for connection to at least one partially surrounded by a cable sheath core of a cable. Furthermore, the invention relates to a system of such a connector and a cable. In particular, the invention relates to a system of a twisted pair cable and a connector with two contact elements.

Twisted-Pair-Kabel sind schon lange aus dem Bereich der Signal- und Datenübertragung bekannt. Mit "Twisted-Pair" werden Kabel bezeichnet, bei denen die Adern (d.h. die jeweils von einem Isoliermantel umgebenen Leiter des Kabels) paarweise miteinander verdrillt sind. Gegenüber Kabeln, bei denen die Adernpaare parallel geführt sind, weisen Twisted-Pair-Kabel mit ihren verdrillten Adernpaaren einen besseren Schutz gegenüber äußeren magnetischen Wechselfeldern und elektrostatischen Beeinflussungen au f, da sich bei einer symmetrischen Signalübertragung durch das Verdrillen der Adernpaare die Beeinflussungen durch äußere Felder größtenteils gegenseitig aufheben.Twisted-pair cables have long been known in the field of signal and data transmission. "Twisted pair" refers to cables in which the wires (i.e., the conductors of the cable each surrounded by an insulating jacket) are twisted together in pairs. Compared to cables in which the wire pairs are routed in parallel, twisted pair cables with their twisted wire pairs better protection against external alternating magnetic fields and electrostatic influences au f, as in a symmetric signal transmission by twisting the wire pairs the influences of external fields mostly cancel each other out.

Steckverbinder kommen zum Einsatz, um elektrisch leitende Bauteile, wie z.B. Kabel, elektrisch leitend miteinander zu verbinden.Connectors are used to connect electrically conductive components, such as e.g. Cable to connect electrically conductive with each other.

Bei der Verbindung eines Twisted-Pair-Kabels mit einem konventionellen Steckverbinder ist vorgesehen, den äußeren, die Adern umgebenden Kabelmantel in einem Abschnitt, mit dem diese innerhalb eines Gehäuses des Steckverbinders geführt werden, zu entfernen. Dann werden die zusätzlich von ihrem Isoliermantel befreiten Enden der Leiter der Adern mit Kontaktelementen des Steckverbinders dauerhaft verbunden. Die Kontaktelemente sind wiederum in dem Gehäuse fixiert. Innerhalb des Gehäuses, d.h. in dem Abschnitt, in dem der Kabelmantel entfernt ist, verlaufen die Adern im Wesentlichen parallel. Dieser Abschnitt des Twisted-Pair-Kabels könnte somit einer stärkeren Beeinflussung durch äußere Felder ausgesetzt sein.When connecting a twisted pair cable with a conventional connector is provided to remove the outer, the wires surrounding cable sheath in a section with which they are guided within a housing of the connector. Then the additionally freed from their insulating ends of the conductors of the wires with contact elements permanently connected to the connector. The contact elements are in turn fixed in the housing. Within the housing, ie in the section in which the cable sheath is removed, the cores run substantially parallel. This section of the twisted pair cable could therefore be more exposed to external fields.

Um eine solche erhöhte Beeinflussung zu vermeiden, ist regelmäßig vorgesehen, in den Steckverbinder und insbesondere das Gehäuse des Steckverbinders eine Schirmung zu integrieren. Dies führt jedoch zu relativ hohen Kosten für den Steckverbinder, da die Möglichkeit entfällt, das Gehäuse kostengünstig ausschließlich aus elektrisch isolierenden bzw. nicht leitenden Kunststoffen auszubilden.To avoid such increased interference, it is regularly provided to integrate a shield into the connector and in particular the housing of the connector. However, this leads to relatively high costs for the connector, since the opportunity is eliminated to form the housing cost-effective exclusively from electrically insulating or non-conductive plastics.

Bei nahezu sämtlichen Systemen aus Steckverbinder und Kabel ist es relevant, eine Zugentlastung für die Verbindung der Adern mit dem Kontaktelement zu schaffen, um zu verhindern, dass eine Zugbelastung auf Steckverbinder und Kabelmantel auf diese Verbindung übertragen wird. Die Integration einer Zugentlastung in ein solches System ist in der Regel mit einem relativ komplexen Aufbau des Steckverbinders und folglich relativ hohen Herstellungskosten sowie mit einer relativ komplexen Montage des Systems und folglich relativ hohen Montagekosten verbunden. Durch die Integration einer Zugentlastung erhöhen sich somit die Stückkosten für das System.Die Druckschriften WO/9701874 A1 , US 6 439 920 B1 und US 4 421 376 A beschreiben jeweils einen Steckverbinder mit einem Gehäuse zur Aufnahme von Kabeln, wobei das Gehäuse mehrere miteinander verbundene Gehäuseteile aufweist.In almost all connector and cable systems, it is important to provide strain relief for the connection of the wires to the contact element to prevent a tensile load on the connector and cable sheath from being transmitted to this connection. The integration of a strain relief in such a system is usually associated with a relatively complex structure of the connector and consequently relatively high manufacturing costs and with a relatively complex assembly of the system and consequently relatively high installation costs. The integration of a strain relief thus increases the unit costs for the system WO / 9701874 A1 . US Pat. No. 6,439,920 B1 and US 4,421,376 A. each describe a connector with a housing for receiving cables, wherein the housing has a plurality of interconnected housing parts.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, ein System aus einem Steckverbinder und einem Kabel, insbesondere Twisted-Pair-Kabel anzugeben, dessen Stückkosten möglichst gering sind.Based on this prior art, the present invention seeks to provide a system of a connector and a cable, in particular twisted pair cable, the unit cost is minimized.

Diese Aufgabe wird durch einen Steckverbinder und ein System gemäß den unabhängigen Ansprüchen gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Steckverbinders und des erfindungsgemäßen Systems sind Gegenstand der jeweiligen abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by a connector and a system according to the solved independent claims. Advantageous embodiments of the connector according to the invention and the system according to the invention are the subject of the respective dependent claims and will become apparent from the following description of the invention.

Ein gattungsgemäßer Steckverbinder mit einem Gehäuse und mindestens einem innerhalb des Gehäuses angeordneten Kontaktelement, das zur Verbindung mit mindestens einer von einem Mantel umgebenen Litze eines Kabels ausgebildet ist, ist erfindungsgemäß dadurch weitergebildet, dass das Gehäuse (ggf. zusätzlich zu weiteren Gehäuseteilen) zwei Gehäuseteile umfasst, die derart ausgebildet sind, dass sie zur Montage des Steckverbinders aneinander gesetzt und durch ein Verschieben relativ zueinander in Längsrichtung des Steckverbinders bis in eine Endstellung verbunden werden, wobei durch das Verschieben ein zur Aufnahme eines Abschnitts des Mantels vorgesehener Teil zumindest eines der Gehäuseteile radial deformiert wird, um den Mantel (vorzugsweise klemmend) zu fixieren.A generic connector with a housing and at least one arranged within the housing contact element, which is designed for connection to at least one of a jacket surrounded strand of a cable, according to the invention further developed in that the housing (possibly in addition to other housing parts) comprises two housing parts , Which are designed such that they are placed together for mounting the connector and connected by a displacement relative to each other in the longitudinal direction of the connector to an end position, wherein deformed by the displacement provided for receiving a portion of the shell part of at least one of the housing parts radially is to fix the coat (preferably clamping).

Als "Längsrichtung" wird erfindungsgemäß diejenige Orientierung verstanden, die durch die Relativbewegung des Steckverbinders zu einem Gegenstecker beim Zusammenstecken dieser Elemente definiert ist. Insbesondere kann die Längsrichtung des Steckverbinders somit entsprechend einer Längsachse des Kontaktelements ausgerichtet sein.According to the invention, the term "longitudinal direction" is understood to mean that orientation which is defined by the relative movement of the connector to a mating connector during mating of these elements. In particular, the longitudinal direction of the connector can thus be aligned according to a longitudinal axis of the contact element.

Bei dem Mantel kann es sich insbesondere um den die Litze direkt umgebenden (Adern-)Mantel (zusammen eine Ader) oder um den mehrere Litzen oder Adern umgebenden Kabelmantel handeln.The sheath can be, in particular, the (sheath) sheath surrounding the strand (together a core) or the sheath surrounding several strands or cores.

Durch die erfindungsgemäße Ausgestaltung des Steckverbinders kann eine Fixierung des Mantels an dem Gehäuse, die die Funktion einer Zugentlastung für die Verbindung zwischen der Ader und dem Kontaktelement übernimmt, auf kostengünstige Art und Weise sowohl hinsichtlich der Herstellungs- als auch der Montagekosten realisiert werden. Hinzu kommt, dass die radiale Deformation des Gehäuses zumindest teilweise auf den regelmäßig flexiblen Mantel übertragen wird, wodurch auch eine Klemmung des oder der innerhalb des Mantels geführten Litzen erfolgt.Due to the inventive design of the connector, a fixation of the jacket to the housing, which performs the function of a strain relief for the connection between the wire and the contact element can be realized in a cost effective manner both in terms of manufacturing and installation costs. In addition, the radial deformation of the housing is at least partially transmitted to the regularly flexible sheath, whereby a clamping of or within the shell guided strands done.

Zur Verbesserung der Fixierung des Mantels in dem Gehäuse kann vorzugsweise vorgesehen sein, dass der radial deformierbare Teil des Gehäuseteils einen Vorsprung aufweist. Dieser Vorsprung kann bei der radialen Deformation in den vorzugsweise aus einem leicht deformierbaren Werkstoff ausgebildeten Mantel eindringen und dadurch eine Art formschlüssige Verbindung ausbilden. Dabei kann der Vorsprung insbesondere (zumindest in einem Abschnitt) teilkreisförmig und/oder im Querschnitt spitz zulaufend ausgebildet sein.To improve the fixation of the shell in the housing may preferably be provided that the radially deformable part of the housing part has a projection. This projection can penetrate in the radial deformation in the preferably formed from a slightly deformable material sheath and thereby form a kind of positive connection. In this case, the projection may in particular (at least in one section) be formed part-circular and / or tapered in cross-section.

Um eine dauerhafte Verbindung der Gehäuseteile in der Endstellung zu gewährleisten, kann vorgesehen sein, dass diese in der Endstellung mittels einer Rastverbindung gegen ein Lösen in Längsrichtung des Steckverbinders gesichert sind. Die Rastverbindung kann dabei unlösbar oder (zerstörungsfrei) lösbar ausgebildet sein.In order to ensure a permanent connection of the housing parts in the end position, it can be provided that they are secured in the end position by means of a latching connection against loosening in the longitudinal direction of the connector. The locking connection can be insoluble or (non-destructive) detachable.

Als "Rastverbindung" wird eine formschlüssige Verbindung verstanden, die durch das federbelastete Eingreifen eines Vorsprungs des einen Gehäuseteils in eine Vertiefung des anderen Gehäuseteils wirkt.As a "locking connection" is understood a positive connection, which acts by the spring-loaded engagement of a projection of a housing part in a recess of the other housing part.

Alternativ oder zusätzlich zu der Rastverbindung können die Gehäuseteile auch kraftschlüssig in der Endstellung verbunden sein.Alternatively or in addition to the latching connection, the housing parts may also be non-positively connected in the end position.

In einer weiterhin bevorzugten Ausgestaltung des erfindungsgemäßen Steckverbinders kann zudem eine Sicherung der Gehäuseteile in der Endstellung gegen ein Lösen quer (insbesondere senkrecht) zur Längsrichtung des Steckverbinders vorgesehen sein. Diese Sicherung kann insbesondere derart ausgebildet sein, dass infolge des Verschiebens mindestens ein Vorsprung eines der Gehäuseteile in mindestens eine entsprechende Vertiefung des anderen Gehäuseteils eingreift.In a further preferred embodiment of the connector according to the invention can also be provided a securing of the housing parts in the end position against loosening transversely (in particular perpendicular) to the longitudinal direction of the connector. This fuse may in particular be designed such that, as a result of the displacement, at least one projection of one of the housing parts engages in at least one corresponding recess of the other housing part.

Ein erfindungsgemäßes System umfasst zumindest einen erfindungsgemäßen Steckverbinder sowie ein daran angeschlossenes Kabel mit mindestens einer von einem Mantel umgebenen Litze, wobei die mindestens eine Litze mit dem mindestens einen Kontaktelement elektrisch leitend verbunden ist und ein Abschnitt des Mantels in zumindest einem der Gehäuseteile fixiert ist.An inventive system comprises at least one connector according to the invention and a cable connected thereto with at least one a strand surrounded by a jacket, wherein the at least one strand is electrically conductively connected to the at least one contact element and a portion of the shell is fixed in at least one of the housing parts.

In einer weiterhin bevorzugten Ausgestaltung des erfindungsgemäßen Steckverbinders sind (mindestens) zwei, vorzugsweise parallel angeordnete Kontaktelemente vorgesehen. Ein solcher Steckverbinder eignet sich für einen Anschluss an die (mindestens) zwei verdrillten Litzen (vorzugsweise Adern) eines Twisted-Pair-Kabel, wie dies in einer bevorzugten Ausgestaltung des erfindungsgemäßen Systems vorgesehen ist.In a further preferred embodiment of the connector according to the invention (at least) two, preferably arranged in parallel contact elements are provided. Such a connector is suitable for connection to the (at least) two twisted strands (preferably wires) of a twisted pair cable, as provided in a preferred embodiment of the system according to the invention.

In einer bevorzugten Ausgestaltung eines solchen erfindungsgemäßen Systems kann dann vorgesehen sein, dass die Litzen oder Adern innerhalb des Gehäuses in einer die Verdrillung des Twisted-Pair-Kabels fortsetzenden (d.h. insbesondere eine identische Schlaglänge aufweisenden) Verdrillung geführt sind. Dabei erfolgt die Fortsetzung der Verdrillung besonders bevorzugt möglichst bis direkt zu den Kontaktelementen.In a preferred embodiment of such a system according to the invention, it can then be provided that the strands or wires are guided within the housing in a twist continuing the twisting of the twisted pair cable (i.e., in particular having an identical lay length). In this case, the continuation of the twist is particularly preferably as far as possible directly to the contact elements.

Durch eine solche Ausgestaltung des erfindungsgemäßen Systems kann erreicht werden, dass die guten Übertragungseigenschaften von Twisted-Pair-Kabeln auch weitgehend für den Steckverbinder erreicht werden, ohne dass es dafür einer Schirmung des Steckverbinders bedarf. Dadurch kann, wie dies vorzugsweise vorgesehen ist, das Gehäuse vollständig aus elektrisch isolierendem Kunststoff ausgebildet sein und insbesondere keine Schirmung ausbilden. Dadurch können die Herstellungskosten für den erfindungsgemäßen Steckverbinder gering gehalten werden. Dies gilt insbesondere dann, wenn, wie weiterhin bevorzugt vorgesehen ist, die Gehäuseteile ohne weitere Nachbearbeitung, wie z.B. einem teilweise metallischen Beschichten, durch Spritzgießen hergestellt werden.By such an embodiment of the system according to the invention can be achieved that the good transmission properties of twisted pair cables are also largely achieved for the connector, without the need for a shielding of the connector. As a result, as is preferably provided, the housing can be formed entirely from electrically insulating plastic and in particular form no shielding. As a result, the manufacturing cost of the connector according to the invention can be kept low. This is especially true if, as further preferred, the housing parts without further post-processing, such as. a partially metallic coating, by injection molding.

Die Fixierung des Mantels in dem Gehäuse des erfindungsgemäßen Steckverbinders kann bereits in ausreichendem Maße dafür sorgen, dass die Verdrillung der Litzen oder Adern innerhalb des Gehäuses fortgesetzt wird. Dies gilt insbesondere, wenn die Fixierung des Kabelmantels (auch) derart ist, dass diese gegen ein Verdrehen des Mantels in dem Gehäuse sichert. Dabei kann sich zudem besonders vorteilhaft auswirken, wenn die radiale Deformation des Gehäuses über den flexiblen Mantel auf die Litzen oder Adern übertragen wird, die somit in der verdrillten Anordnung geklemmt und dadurch fixiert werden. Alternativ oder zusätzlich kann das Gehäuse des erfindungsgemäßen Steckverbinders aber auch so ausgebildet sein, dass es eine Führung ausbildet, durch die die Litzen oder Adern in einer die Verdrillung des Twisted-Pair-Kabels fortsetzenden Verdrillung fixiert sind. Beispielsweise können die Wände eines Führungsraums des Gehäuses entsprechend der Raumform der in der vorgesehenen Verdrillung geführten Litzen oder Adern ausgebildet sein. Alternativ oder zusätzlich dazu können auch mindestens ein, vorzugsweise zwei oder mehr Führungszapfen vorgesehen sein, die in dem Führungsraum, in dem die Litzen oder Adern geführt sind, angeordnet sind. Um diese Zapfen können die Litzen oder Adern bogenförmig herumgeführt sein, wodurch in Verbindung mit den Innenwänden des Führungsraums die Verdrillung der Litzen oder Adern fixiert sein kann. Dabei erstrecken sich die Zapfen vorzugsweise quer und insbesondere senkrecht zu einer Ebene, die von Längsachsen der zwei, vorzugsweise eine längliche und insbesondere zylindrische Form aufweisenden Kontaktelemente aufgespannt wird. Dabei kann besonders bevorzugt vorgesehen sein, dass die Zapfen in einem identischen Abstand zu den Längsachsen der beiden Kontaktelemente angeordnet sind. Dadurch wird eine grundsätzlich angestrebte, weitgehend symmetrische Führung der Litzen oder Adern und damit eine weitgehend übereinstimmende Länge der in dem Gehäuse geführten Abschnitte der Litzen oder Adern des Twisted-Pair-Kabels unterstützt, was sich positiv auf die elektrischen Eigenschaften des erfindungsgemäßen Systems auswirken kann.The fixation of the jacket in the housing of the connector according to the invention can already sufficiently ensure that the twisting of the strands or wires is continued within the housing. This is especially true if the fixation of the cable sheath is (also) such that this secures against rotation of the shell in the housing. It may also be particularly advantageous if the radial deformation of the housing is transmitted through the flexible sheath on the strands or cores, which are thus clamped in the twisted arrangement and thereby fixed. Alternatively or additionally, however, the housing of the connector according to the invention can also be designed such that it forms a guide, by means of which the strands or wires are fixed in a twist continuing the twisting of the twisted pair cable. For example, the walls of a guide space of the housing may be formed according to the spatial shape of the guided in the intended twist strands or wires. Alternatively or additionally, at least one, preferably two or more guide pins may be provided, which are arranged in the guide space in which the strands or wires are guided. Around these pins, the strands or wires can be guided around an arc, whereby in connection with the inner walls of the guide space, the twist of the strands or wires can be fixed. In this case, the pins preferably extend transversely and in particular perpendicular to a plane which is spanned by longitudinal axes of the two, preferably an elongated and in particular cylindrical shape having contact elements. It can be particularly preferably provided that the pins are arranged at an identical distance to the longitudinal axes of the two contact elements. As a result, a basically desired, largely symmetrical guidance of the strands or cores and thus a largely coincident length of the guided in the housing portions of the strands or cores of the twisted pair cable is supported, which can have a positive effect on the electrical properties of the system according to the invention.

Die Fig. 1 zeigt ein erfindungsgemäßes System, das einen erfindungsgemäßen Steckverbinder 1 und ein damit elektrisch und mechanisch verbundenes (Twisted-Pair-)Kabel 2 mit zwei verdrillten Adern 3 umfasst.The Fig. 1 shows a system according to the invention comprising a connector 1 according to the invention and a thus electrically and mechanically connected (twisted pair) cable 2 with two twisted wires 3.

Der Steckverbinder 1 weist neben einem zweiteiligen Gehäuse zwei Kontaktelemente 4 auf, die in dem Gehäuse fixiert gelagert sind und steckseitige sowie kabelseitige Enden aufweisen. An den kabelseitigen Enden sind die Kontaktelemente 4 über Crimpverbindungen mit jeweils einem abisolierten Abschnitt der Litze eines der zwei Adern 3 des Kabels 2 verbunden. Die steckseitigen Enden sind dazu vorgesehen, komplementäre Kontaktelemente eines Gegensteckverbinders (nicht dargestellt) zu kontaktieren, wobei die buchsenförmigen Kontaktelemente 4 des Steckverbinders 1 stiftförmige Kontaktelemente des Gegensteckverbinders aufnehmen und dabei radial elastisch aufgeweitet werden, was durch eine entsprechende Längsschlitzung der Kontaktelemente ermöglicht wird.The connector 1 has in addition to a two-part housing two contact elements 4 which are mounted fixed in the housing and have plug-side and cable-side ends. At the cable-side ends, the contact elements 4 are connected via crimped connections, each having a stripped section of the strand of one of the two wires 3 of the cable 2. The plug-side ends are intended to contact complementary contact elements of a mating connector (not shown), wherein the socket-shaped contact elements 4 of the connector 1 record pin-shaped contact elements of the mating connector and thereby radially expanded, which is made possible by a corresponding longitudinal slitting of the contact elements.

Die Lagefixierung der Kontaktelemente 4 in dem Gehäuse wird durch jeweils einen umlaufenden Vorsprung 5 der Kontaktelemente 4 realisiert, der in einer umlaufenden Nut des Gehäuses angeordnet ist.The fixing of the position of the contact elements 4 in the housing is realized by a respective circumferential projection 5 of the contact elements 4, which is arranged in a circumferential groove of the housing.

Das Gehäuse des Steckverbinders umfasst zwei Gehäuseteile, ein erster, in der Fig. 1 unten dargestellter Gehäuseteil 6 sowie ein zweiter, in der Fig. 1 oben dargestellter Gehäuseteil 7. Jeder der Gehäuseteile 6, 7 umfasst einen steckseitigen Abschnitt, in dem im montierten Zustand des Steckverbinders 1 die Kontaktelemente 4 angeordnet sind. In diesem Abschnitt verläuft die Trennebene zwischen den Gehäuseteilen 6, 7 koplanar zu derjenigen Ebene, die von den Längsachsen der beiden (mit Ausnahme der Crimpverbindungen kreis- oder ringförmige Querschnitte aufweisenden) Kontaktelemente 4 aufgespannt wird. Weiterhin umfasst jeder Gehäuseteil 6, 7 einen kabelseitigen Abschnitt, der zur Aufnahme des in dem Gehäuse aufgenommenen Abschnitts des Kabels 2 vorgesehen ist. In diesem Abschnitt verläuft die Trennebene parallel zu der von den Längsachsen der beiden Kontaktelemente 4 aufgespannten Ebene.The housing of the connector comprises two housing parts, a first, in the Fig. 1 shown below housing part 6 and a second, in the Fig. 1 Each of the housing parts 6, 7 comprises a plug-side section, in which the contact elements 4 are arranged in the assembled state of the connector 1. In this section, the parting plane between the housing parts 6, 7 extends coplanar to that plane which is circular or parallel to the longitudinal axes of the two (with the exception of the crimp connections) annular cross-sections having) contact elements 4 is clamped. Furthermore, each housing part 6, 7 comprises a cable-side section, which is provided for receiving the accommodated in the housing portion of the cable 2. In this section, the parting line runs parallel to the plane spanned by the longitudinal axes of the two contact elements 4 level.

In dem jeweiligen kabelseitigen Abschnitt bilden beide Gehäuseteile 6, 7 an die Trennebene angrenzend jeweils vier Vorsprünge 8 aus, wobei jeweils zwei Vorsprünge 8 in Längsrichtung des Steckverbinders voneinander beabstandet auf jeder Seite beider Gehäuseteile 6, 7 angeordnet sind. Die jeweils zwei Vorsprünge 8 bilden weiterhin eine Begrenzung für eine sich in Längsrichtung erstreckende Vertiefung 9 auf jeder Seite beider Gehäuseteile 6, 7 aus.In the respective cable-side section, the two housing parts 6, 7 each form four projections 8 adjacent to the dividing plane, wherein two projections 8 are arranged spaced apart in the longitudinal direction of the connector on each side of both housing parts 6, 7. The two projections 8 further form a boundary for a recess 9 extending in the longitudinal direction on each side of both housing parts 6, 7.

Zur Montage des Steckverbinders 1 werden die beiden Gehäuseteile 6, 7 in Längsrichtung derart zueinander versetzt positioniert, dass die Vorsprünge 8 des einen Gehäuseteils 6, 7 neben den Vorsprüngen 8 des anderen Gehäuseteils 7, 6 angeordnet sind. Dadurch können die Gehäuseteile 6, 7 bis zu einem Kontakt der die Trennebene ausbildenden Kontaktflächen beider Gehäuseteile 6, 7 (in einer Richtung senkrecht zur Längsrichtung) zusammengesteckt werden, ohne dass die Vorsprünge 8 kollidieren. Die Vorsprünge 8 beider Gehäuseteile 6, 7 befinden sich dann in den Vertiefungen 9 des jeweils anderen Gehäuseteils 7, 6.For mounting the connector 1, the two housing parts 6, 7 are positioned offset from one another in the longitudinal direction such that the projections 8 of one housing part 6, 7 are arranged next to the projections 8 of the other housing part 7, 6. As a result, the housing parts 6, 7 can be plugged together (up to a contact of the separating plane forming contact surfaces of the two housing parts 6, 7 (in a direction perpendicular to the longitudinal direction) without the projections 8 collide. The projections 8 of both housing parts 6, 7 are then in the recesses 9 of the other housing part 7, the sixth

Eine Verbindung der Gehäuseteile 6, 7 erfolgt anschließend durch ein Verschieben der beiden Gehäuseteile 6, 7 relativ zueinander in Längsrichtung, bis die in der Fig. 1 dargestellte Endstellung erreicht ist. In dieser Endstellung überdecken die vier Vorsprünge 8 beider Gehäuseteile 6, 7 einander zumindest teilweise. Dadurch wird verhindert, dass sich die Gehäuseteile 6, 7 in einer Richtung quer zur Längsrichtung des Steckverbinders 1 voneinander lösen können.A connection of the housing parts 6, 7 is then carried out by a displacement of the two housing parts 6, 7 relative to each other in the longitudinal direction until the in the Fig. 1 shown end position is reached. In this end position cover the four projections 8 of the two housing parts 6, 7 each other at least partially. This prevents that the housing parts 6, 7 in a direction transverse to the longitudinal direction of the connector 1 can separate from each other.

Ein Lösen der Gehäuseteile 6, 7 voneinander in Längsrichtung wird durch eine Rastverbindung verhindert. Die Rastverbindung wird von den zwei kabelseitig gelegenen Vorsprüngen 8a des ersten Gehäuseteils 6 im Zusammenwirken mit einem kabelseitigen Endabschnitt 10 des zweiten Gehäuseteils 7 ausgebildet.A release of the housing parts 6, 7 from each other in the longitudinal direction is prevented by a latching connection. The latching connection is formed by the two cable-side projections 8a of the first housing part 6 in cooperation with a cable-side end portion 10 of the second housing part 7.

Diese Vorsprünge 8a sind sich in Richtung des kabelseitigen Endes des ersten 6 Gehäuseteils verbreiternd ausgebildet, wodurch schräg zur Längsrichtung verlaufende Kontaktflächen der Vorsprünge 8a ausgebildet werden. Auf diese Kontaktflächen wird der Endabschnitt 10 des zweiten Gehäuseteils 7 aufgeschoben, wobei die Innenbreite des Endabschnitts 10 kleiner als die von den beiden sich verbreiternden Vorsprüngen 8a definierte Maximalbreite ist. Der Endabschnitt 10 des zweiten Gehäuseteils 7 wird daher beim Überfahren der sich verbreiternden Vorsprünge 8a elastisch aufgeweitet und schnappt dadurch in der Endstellung hinter diese Vorsprünge 8a.These projections 8a are widening in the direction of the cable end of the first housing part 6, whereby obliquely to the longitudinal direction extending contact surfaces of the projections 8a are formed. The end section 10 of the second housing part 7 is pushed onto these contact surfaces, wherein the inner width of the end section 10 is smaller than the maximum width defined by the two widening projections 8a. The end portion 10 of the second housing part 7 is therefore expanded elastically when passing over the widening projections 8a and thereby snaps in the end position behind these projections 8a.

Beim Einschnappen hinter die Vorsprünge 8a kann sich der Endabschnitt 10 des zweiten Gehäuseteils 7 jedoch nicht wieder vollständig zurückverformen, sondern dieser schlägt unter elastischer Aufweitung an Kontaktflächen eines Endabschnitts 11 des ersten Gehäuseteils 6 an. Im Bereich dieser Kontaktflächen weist der erste Gehäuseteil 6 dazu eine größere Breite als im Bereich der Vertiefungen 9 auf.When snapping behind the projections 8a, the end portion 10 of the second housing part 7, however, can not fully deform back again, but this strikes with elastic expansion of contact surfaces of an end portion 11 of the first housing part 6. In the area of these contact surfaces, the first housing part 6 has a greater width than in the region of the depressions 9.

Durch das Anliegen des Endabschnitts 10 des zweiten Gehäuseteils 7 unter elastischer Aufweitung und damit Vorspannung wird der Endabschnitt 11 und teilweise der sich daran anschließende Abschnitt des ersten Gehäuseteils 6 radial nach innen deformiert, wodurch sich der in dem ersten Gehäuseteil 6 ausgebildete Aufnahmeraum in diesen Abschnitten verkleinert. Dies führt zu einer klemmenden Fixierung des in diesen Abschnitten vorgesehenen Kabelmantels 12 des Kabels 2. Diese Fixierung dient zum einen als Zugentlastung für die Verbindung zwischen den Kontaktelementen 4 und den Leitern des Kabels 2 und soll zum anderen ein Verdrehen des Kabels 2 in dem Gehäuse verhindern.Due to the abutment of the end portion 10 of the second housing part 7 under elastic expansion and thus bias the end portion 11 and partially of the adjoining portion of the first housing part 6 is deformed radially inwardly, whereby the formed in the first housing part 6 receiving space is reduced in these sections , This fixation serves for a strain relief for the connection between the contact elements 4 and the conductors of the cable 2 and is intended to prevent twisting of the cable 2 in the housing ,

Verbessert wird die Verbindung des Kabels 2 in dem Gehäuse noch durch einen in der Wand des Aufnahmeraums (um die Längsrichtung des Steckverbinders) umlaufenden, in der Nähe des Endabschnitts 11 angeordneten Vorsprung 13, der eine spitz zulaufende Querschnittsfläche aufweist. Dieser Vorsprung 13 dringt infolge der Deformation des ersten Gehäuseteils 6 in den Kabelmantel 12 ein und bildet dadurch eine Art formschlüssige Verbindung aus.The connection of the cable 2 in the housing is further improved by a projection 13 which is arranged in the wall of the receiving space (around the longitudinal direction of the connector) and is arranged near the end section 11 and which has a tapered cross-sectional area. This projection 13 penetrates due to the deformation of the first housing part 6 in the cable sheath 12 and thereby forms a kind of positive connection.

Die Adern 3 des Kabels 2 weisen auch in dem von dem Kabelmantel 12 befreiten Abschnitt innerhalb des Gehäuses eine verdrillte Anordnung auf. Dabei entspricht die Verdrillung in diesem Abschnitt möglichst derjenigen, die die Adern 3 innerhalb des Kabelmantels 12 aufweisen. Durch die Festlegung der steckseitigen Enden der Leiter in den Kontaktelementen 4, die wiederum innerhalb des Gehäuses fixiert sind, sowie durch die Sicherung des Kabelmantels 12 gegen ein Verdrehen durch die klemmende Fixierung kann in ausreichendem Maße sichergestellt werden, dass sich die Verdrillung in dem von dem Kabelmantel 12 befreiten Abschnitt des Kabels 2 nicht auflöst.The wires 3 of the cable 2 also have a twisted arrangement in the section freed from the cable sheath 12 inside the housing. The twist in this section corresponds as possible to those that have the wires 3 within the cable sheath 12. By fixing the plug-side ends of the conductors in the contact elements 4, which in turn are fixed within the housing, and by securing the cable sheath 12 against rotation by the clamping fixation can be sufficiently ensured that the twist in the of the Cable sheath 12 liberated portion of the cable 2 does not dissolve.

Die beiden Gehäuseteile 6, 7 des Steckverbinders 1 sind vollständig aus elektrisch nicht leitendem Kunststoff ausgebildet, wobei die einfache geometrische Form ein Spritzgießen vorteilhaft ermöglicht. Bei einer Entformungsrichtung, die senkrecht zu den Trennebenen ausgerichtet ist, weist lediglich der zweite Gehäuseteil 7 Hinterschnitte in Form von steckseitigen Durchgangsöffnungen 14 auf, die mit Hilfe eines Schiebers der Spritzgießform erzeugt werden können. Die Vorsprünge 8 stellen durch das Vorsehen von Entformungsvertiefungen 15 keine Hinterschnitte bei der Entformung dar.The two housing parts 6, 7 of the connector 1 are formed entirely of electrically non-conductive plastic, the simple geometric shape advantageously allows injection molding. In a demolding, which is aligned perpendicular to the parting planes, only the second housing part 7 has undercuts in the form of plug-through openings 14, which can be generated by means of a slide of the injection mold. The projections 8 represent by the provision of Entformungsvertiefungen 15 no undercuts during demolding.

Eine in das Gehäuse integrierte Schirmung für den Steckverbinder ist nicht vorgesehen. Infolge der im Wesentlichen bis zu den Kontaktelementen 4 fortgesetzten Verdrillung der Adern 3 ist das Übertragungsverhalten für Hochfrequenzsignale des Systems für viele Anwendungen ausreichend gut.An integrated into the housing shield for the connector is not provided. Due to the twisting of the cores 3, which continues substantially as far as the contact elements 4, the transmission behavior for high-frequency signals of the system is sufficiently good for many applications.

Zur Montage des Systems wird zunächst ein definierter Abschnitt des Kabels 2 von dem Kabelmantel 12 befreit. Dieser Abschnitt ist so bemessen, dass sich der Kabelmantel 12 im montierten Zustand mit definierter Länge bis in den Aufnahmeraum des Gehäuses erstreckt. Daraufhin werden die Adern 3 an ihrem steckseitigen Ende in definierten Abschnitten abisoliert, d.h. die Leiter der Adern 3 werden in diesen Abschnitten von Schutzhüllen befreit. Die abisolierten Enden der Leiter werden dann mit den Kontaktelementen 4 durch Crimpen verbunden. Daraufhin werden die Kontaktelemente 4 und der vorgesehene Kabelabschnitt in den ersten Gehäuseteil 6 eingelegt, wobei die vorgesehene Verdrillung des freigelegten Abschnitts der Ader 3 eingebracht wird. Eine bereits leichte Klemmung des Kabelmantels 12 in dem Endabschnitt 11 des ersten Gehäuseteils 6 infolge eines Übermaßes des Kabelmantels 12 sowie die Fixierung der Kontaktelemente 4 durch Rastverbindungen, die durch jeweils zwei Rastlaschen 16 erreicht wird, verhindern dabei bereits ein Auflösen der Verdrillung der freigelegten Adern 3. Daraufhin wird der zweite Gehäuseteil 7 in der bereits beschriebenen Art und Weise auf den ersten Gehäuseteil 6 aufgeschoben. Durch die dann verstärkte Fixierung des Kabelmantels 12 in dem Gehäuse infolge der radialen Deformation des ersten Gehäuseteils 6 wird die Zugentlastung realisiert und ein Auflösen der Verdrillung auch bei der späteren Nutzung des Systems mit relativ großen Handhabungskräften verhindert.To assemble the system, a defined section of the cable 2 is first removed from the cable sheath 12. This section is dimensioned so that the cable sheath 12 extends in the assembled state with a defined length to the receiving space of the housing. Then the wires 3 are stripped at their plug-side end in defined sections, ie the conductors of the wires 3 are freed in these sections of protective covers. The stripped ends of the conductors are then connected to the contact elements 4 by crimping. Then, the contact elements 4 and the intended cable section are inserted into the first housing part 6, wherein the intended twist of the exposed portion of the wire 3 is introduced. An already slight clamping of the cable sheath 12 in the end portion 11 of the first housing part 6 due to an excess of the cable sheath 12 and the fixation of the contact elements 4 by snap-in connections, which is achieved by two locking tabs 16, thereby preventing already a dissolution of the twist of the exposed wires. 3 Subsequently, the second housing part 7 is pushed onto the first housing part 6 in the manner already described. By then strengthened fixation of the cable sheath 12 in the housing due to the radial deformation of the first housing part 6, the strain relief is realized and prevents dissolution of the twist even in the later use of the system with relatively large handling forces.
