Description

Steckverbinder  Connectors
Die Erfindung betrifft einen Steckverbinder mit einem Gehäuse und mindestens zwei innerhalb des Gehäuses fixierten Kontaktelementen, die zur Verbindung mit zwei Adern eines Twisted-Pair-Kabels ausgebildet sind. Weiterhin betrifft die Erfindung ein System aus einem solchen Steckverbinder und einem Twisted- Pair-Kabel sowie ein Verfahren zur Herstellung eines solchen Systems. The invention relates to a connector with a housing and at least two fixed within the housing contact elements, which are designed for connection to two wires of a twisted pair cable. Furthermore, the invention relates to a system of such a connector and a twisted-pair cable and a method for producing such a system.
Twisted-Pair-Kabel sind schon lange aus dem Bereich der Signal- und Datenübertragung bekannt. Mit Twisted-Pair werden Kabel bezeichnet, bei denen die Adern (die von einem Isoliermantel umgebenen Leiter) 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 auf, 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 (conductors 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 provide better protection against external magnetic alternating fields and electrostatic influences, since in a symmetrical signal transmission by twisting the wire pairs, the effects of external fields largely 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 herkömmlichen Steckverbinder ist vorgesehen, den äußeren, die Adern umgebenden Schutzmantel in einem definierten Abschnitt, in dem diese innerhalb eines Gehäuses des Steckverbinder geführt werden, zu entfernen. Dann werden die von ihrer Isolierung befreiten Enden 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 Schutzmantel 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 to a conventional one Connector is provided to remove the outer, the wires surrounding protective jacket in a defined section in which they are guided within a housing of the connector. Then the freed from their insulation ends of the wires are permanently connected to contact elements of the connector. The contact elements are in turn fixed in the housing. Within the housing, ie in the section in which the protective jacket is removed, the wires are 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 aus einem elektrisch isolierenden bzw. nicht leitenden Kunststoff 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 possibility is eliminated, the housing inexpensively from an electrically insulating or non-conductive plastic form.
Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, ein System aus einem Steckverbinder und einem Twisted-Pair-Kabel anzugeben, dessen Herstellungskosten möglichst gering sind. Based on this prior art, the present invention seeks to provide a system of a connector and a twisted pair cable, the production costs are minimized.
Diese Aufgabe wird durch einen Steckverbinder und ein System gemäß den unabhängigen Patentansprüchen 1 und 7 gelöst. Ein Verfahren zur Herstellung eines erfindungsgemäßen Systems ist Gegenstand des unabhängigen Patentanspruchs 9. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Steckverbinders und des erfindungsgemäßen Systems sind Gegenstand der abhängigen Patentansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung. This object is achieved by a connector and a system according to independent claims 1 and 7. A method for producing a system according to the invention is the subject of independent claim 9. Advantageous embodiments of the connector according to the invention and of the system according to the invention are the subject of the dependent claims and will become apparent from the following description of the invention.
Der Erfindung liegt der Gedanke zugrunde, die Herstellungskosten für einen Steckverbinder, der zur Verbindung mit einem Twisted-Pair-Kabel vorgesehen ist, und dadurch auch die Herstellungskosten für ein System aus einem Steckverbinder und einem Twisted-Pair-Kabel dadurch zu reduzieren, dass auf die Integration einer Schirmung in das Gehäuse des Steckverbinders verzichtet wird. Um dabei keine wesentlichen Verschlechterung der elektrischen Eigenschaften in Kauf nehmen zu müssen, ist ein weiterer Grundgedanke der Erfindung, die Verdrillung der Adern des Twisted-Pair-Kabels auch in dem Abschnitt, in dem dieses von dem Schutzmantel befreit und innerhalb des Gehäuses geführt ist, nicht aufzulösen, sondern vorzugsweise identisch fortzusetzen. Die vorteilhaften elektrischen Eigenschaften, die Twisted-Pair- Kabel infolge der Verdrillung der Adern aufweisen, können somit auch auf den Steckverbinder übertragen werden, ohne dass es hierfür einer Integration einer Schirmung bedarf. The invention is based on the idea of reducing the manufacturing cost of a connector, which is intended for connection to a twisted pair cable, and thereby also reduce the manufacturing cost of a system of a connector and a twisted pair cable, that on the integration of a shield in the housing of the connector is dispensed with. In order thereby no substantial deterioration of the electrical To accept properties, another basic idea of the invention is not to dissolve the twist of the wires of the twisted pair cable even in the section in which it is removed from the protective jacket and routed inside the housing, but preferably continues identically , The advantageous electrical properties, the twisted pair cables have due to the twisting of the wires can thus be transferred to the connector, without the need for integration of a shielding.
Ein erfindungsgemäßer Steckverbinder umfasst somit zumindest ein Gehäuse und mindestens zwei innerhalb des Gehäuses fixierte Kontaktelemente, die zur Verbindung mit zwei Adern eines Twisted-Pair-Kabels ausgebildet und für einen Kontakt mit Kontaktelementen eines Gegensteckverbinders vorgesehen sind, wobei das Gehäuse eine Führung ausbildet, durch die die Adern in einer die Verdrillung des Twisted-Pair-Kabels fortsetzenden Verdrillung fixiert sind. Durch die Führung des Gehäuses wird ein Auflösen der Verdrillung verhindert und somit das Fehlen des äußeren Schutzmantels, der bei Twisted-Pair-Kabeln die Lage der Adern zueinander und somit die Verdrillung fixiert, kompensiert. An inventive connector thus comprises at least one housing and at least two fixed within the housing contact elements, which are designed for connection to two wires of a twisted pair cable and provided for contact with contact elements of a mating connector, wherein the housing forms a guide through which the cores are fixed in a twist which continues the twist of the twisted pair cable. By guiding the housing, a dissolution of the twisting is prevented and thus the absence of the outer protective jacket, which fixes the position of the wires to each other and thus the twisting in twisted-pair cables, compensates.
Ein entsprechendes erfindungsgemäßes System aus einem Steckverbinder, der zumindest ein Gehäuse und mindestens zwei innerhalb des Gehäuses fixierte Kontaktelemente aufweist, und einem Twisted-Pair-Kabel, wobei zwei Adern des einen Twisted-Pair-Kabels mit den Kontaktelementen elektrisch leitend verbunden sind, ist dadurch gekennzeichnet, dass die Adern innerhalb des Gehäuses in einer die Verdrillung des Twisted-Pair-Kabels fortsetzenden Verdrillung geführt sind. Dabei ist vorzugsweise vorgesehen, dass der Steckverbinder erfindungsgemäß ausgebildet ist, d.h. dessen Gehäuse eine Führung ausbildet, durch die die Adern in einer die Verdrillung des Twisted-Pair- Kabels fortsetzenden Verdrillung fixiert sind. Alternativ besteht auch die Möglichkeit, dass die Fixierung der Verdrillung der innerhalb des Gehäuses des Steckverbinders geführten Adern durch andere Maßnahmen erreicht wird, beispielweise indem die Leiter in ein separates Bauteil oder in eine aushärtende Masse integriert werden, oder der Schutzmantel des Twisted-Pair-Kabels bis weit in das Gehäuse und vorzugsweise bis zu den Kontaktelementen hinein fortgesetzt wird. A corresponding inventive system comprising a connector having at least one housing and at least two fixed contact elements within the housing, and a twisted pair cable, wherein two wires of a twisted pair cable are electrically connected to the contact elements is characterized characterized in that the wires are guided within the housing in a twinning continuing the twisting of the twisted pair cable. In this case, it is preferably provided that the connector is designed according to the invention, that is, the housing forms a guide, by which the wires are fixed in a twisting of the twisted pair cable continuation. Alternatively, there is also the possibility that the fixation of the twist of the guided inside the housing of the connector wires is achieved by other measures, for example by the conductors are integrated into a separate component or in a hardening mass, or the protective sheath of the twisted pair cable far into the housing and preferably into the contact elements will continue.
Besonders gute elektrische Eigenschaften des erfindungsgemäßen Steckverbinders können dadurch erzielt werden, dass die Adern möglichst bis direkt zu den Kontaktelementen in der Verdrillung geführt sind. Particularly good electrical properties of the connector according to the invention can be achieved in that the wires are guided as far as possible directly to the contact elements in the twist.
Ein wesentlicher Vorteil des erfindungsgemäßen Steckverbinders ist, dass dieser infolge der weitergeführten Verdrillung der Adern in dem Gehäuse auch ohne zusätzliche Schirmung relativ unempfindlich gegenüber Störungen durch äußere Felder ist. Dementsprechend ist in einer bevorzugten Ausführungsform des erfindungsgemäßen Steckverbinders auch vorgesehen, dass das Gehäuse keine Schirmung aufweist. Dies ermöglicht eine besonders bevorzugte Weiterbildung, bei der das Gehäuse (vorzugsweise vollständig) aus elektrisch isolierendem Kunststoff ausgebildet ist. Ein solches Gehäuse kann kostengünstig in hohen Stückzahlen als Spritzgussbauteil hergestellt werden. A significant advantage of the connector according to the invention is that this is relatively insensitive to interference from external fields due to the continued twisting of the wires in the housing even without additional shielding. Accordingly, it is also provided in a preferred embodiment of the connector according to the invention that the housing has no shielding. This allows a particularly preferred development, in which the housing is formed (preferably completely) of electrically insulating plastic. Such a housing can be inexpensively manufactured in large quantities as an injection molded component.
Zur Ausbildung der Führung in dem Gehäuse kann vorzugsweise vorgesehen sein, dass das Gehäuse mindestens einen, vorzugsweise zwei oder mehr Führungszapfen aufweist, die sich in einen von dem Gehäuse ausgebildeten Führungsraum, in dem die Adern geführt sind, erstrecken. Um diese Zapfen sind die Adern bogenförmig herumgeführt, wodurch in Verbindung mit den Innenwänden des Führungsraums die Verdrillung der Adern fixiert sein kann. Dabei erstrecken sich die Zapfen vorzugsweise quer und insbesondere senkrecht zu einer Ebene, die von Längsachsen der eine längliche und insbesondere zylindrische Form aufweisenden Kontaktelemente aufgespannt wird. To form the guide in the housing may preferably be provided that the housing has at least one, preferably two or more guide pins which extend into a housing formed by the guide space in which the wires are guided. Around these pins, the wires are guided around arcuate, which can be fixed in conjunction with the inner walls of the guide space, the twisting of the wires. In this case, the pins preferably extend transversely and in particular perpendicular to a plane which is spanned by longitudinal axes of the contact elements having an elongate and, in particular, cylindrical shape.
Dabei kann besonders bevorzugt vorgesehen sein, dass die Zapfen in einem identischen Abstand zu den Längsachsen der beiden Kontaktelemente angeordnet sind. Durch diese Ausgestaltung kann erreicht werden, dass die in dem Gehäuse geführten Abschnitte der Adern des Twisted-Pair-Kabels im Wesentlichen dieselbe Länge aufweisen, was sich grundsätzlich positiv auf die elektrischen Eigenschaften des erfindungsgemäßen Systems auswirkt. Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Steckverbinders, die insbesondere eine Herstellung des Gehäuses durch Spritzgießen sowie dessen Montage vereinfachen kann, kann vorsehen, dass das Gehäuse zweiteilig ausgeführt ist, wobei die Teilung in denjenigen Seitenwänden vorgesehen ist, die von der von den Längsachsen der Kontaktelemente aufgespannten Ebene gekreuzt werden. Besonders bevorzugt kann/können die Trennebene(n) parallel zu dieser von den Längsachsen der Kontaktelemente aufgespannten Ebene verlaufen. In Verbindung mit Führungszapfen, die im Wesentlichen senkrecht zu der von den Längsachsen der Kontaktelemente aufgespannten Ebene verlaufen, können die Gehäusehälften somit (bezogen auf eine Entformungsrichtung) keine Hinterschnitte aufweisen und daher in Spritzgießwerkzeugen hergestellt werden, die ohne z.B. Schieber auskommen. 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 of this embodiment, it is possible to ensure that the sections of the wires of the twisted pair cable routed in the housing have substantially the same length, which basically has a positive effect on the electrical properties of the system according to the invention. A further advantageous embodiment of the connector according to the invention, which in particular can simplify a production of the housing by injection molding and its assembly, can provide that the housing is made in two parts, wherein the division is provided in those side walls which are spanned by the of the longitudinal axes of the contact elements Level to be crossed. Particularly preferably, the parting plane (s) can run parallel to this plane spanned by the longitudinal axes of the contact elements. In conjunction with guide pins, which extend substantially perpendicular to the plane spanned by the longitudinal axes of the contact elements plane, the housing halves thus (relative to a Entformungsrichtung) have no undercuts and therefore be manufactured in injection molds that do without eg slide.
Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines erfindungsgemäßen Systems mit den Schritten: The invention further relates to a method for producing a system according to the invention with the steps:
- Verbinden der Adern mit den Kontaktelementen;  - connecting the wires with the contact elements;
- Verdrillen eines ersten, den Kontaktelementen benachbarten Abschnitts der Adern;  - Twisting a first, the contact elements adjacent portion of the wires;
- Fixieren des ersten Abschnitts der Adern mit der Verdrillung in dem Gehäuse; - Fixing the first portion of the wires with the twist in the housing;
- Verdrillen des restlichen Abschnitts der Adern. - Twisting the remaining section of the wires.
Ein Vorteil des erfindungsgemäßen Verfahrens ist, dass der Steckverbinder vorteilhaft zur Einspannung der Adern in einer Verdrillungsvorrichtung eingesetzt werden kann. An advantage of the method according to the invention is that the plug connector can advantageously be used for clamping the wires in a twisting device.

Die Fig. 1 und 2 zeigen eine Steckverbindung aus einem Mehrfachsteckverbinder 1 und einem als Gegensteckverbinder dienenden (Mehrfach- )Leiterplattensteckverbinder 2. 1 and 2 show a connector of a multiple connector 1 and serving as a mating connector (multiple) PCB connector. 2
Der Mehrfachsteckverbinder 1 umfasst ein Gehäuse 3 mit einer Mehrzahl (im vorliegenden Ausführungsbeispiel insgesamt fünf) parallel angeordneten Aufnahmeöffnungen. In diese Aufnahmeöffnungen ist jeweils ein erfindungsgemäßer Steckverbinder 4 mit daran angeschlossenem Twisted-Pair- Kabel (wovon nur Abschnitte der Adern 5 dargestellt sind) eingesteckt und dort über eine Rastverbindung lagegesichert. Die Rastverbindung wird jeweils von einem Vorsprung 6, der auf einer Außenseite eines Gehäuses 7 des jeweiligen Steckverbinders 4 ausgebildet ist, und einem Hinterschnitt in Form einer Durchgangsöffnung 8, die von einer Rastlasche 9 des Gehäuses 3 des Mehrfach-Steckverbinders 1 ausgebildet ist, gebildet. Beim Einstecken der Steckverbinder 4 in die Aufnahmeöffnungen lenken die schräg ansteigenden Vorsprünge 6 die Rastlaschen 9 aus, bis die Vorsprünge 6 in die Durchgangsöffnungen 8 der Rastlaschen 9 eingreifen. Zum Lösen der Rastverbindung besteht die Möglichkeit die jeweilige Rastlasche 9 manuell anzuheben und dadurch aus dem Eingriff mit dem dazugehörigen Vorsprung zu bringen. The multiple connector 1 comprises a housing 3 with a plurality (in the present embodiment, a total of five) arranged in parallel receiving openings. In each of these receiving openings an inventive connector 4 with connected thereto twisted pair cable (of which only sections of the wires 5 are shown) inserted and there secured in position via a latching connection. The locking connection is in each case by a projection 6 which is formed on an outer side of a housing 7 of the respective connector 4, and an undercut in the form of a through hole 8, of a latching tab 9 of the housing 3 of the Multiple connector 1 is formed formed. When inserting the connector 4 into the receiving openings, the obliquely rising projections 6 deflect the locking tabs 9 until the projections 6 engage in the passage openings 8 of the locking tabs 9. To release the locking connection, it is possible to manually raise the respective locking tab 9 and thereby bring out of engagement with the associated projection.
Das Gehäuse 7 des Mehrfachsteckverbinders 1 umfasst weiterhin zwei seitliche Rastlaschen 10, die zur Ausbildung einer Rastverbindung mit einem Gehäuse 11 des Leiterplattensteckverbinders 2 vorgesehen sind, das dazu entsprechend schräg ansteigende Vorsprünge 12 umfasst. The housing 7 of the multiple connector 1 further comprises two lateral locking tabs 10, which are provided for forming a latching connection with a housing 11 of the printed circuit board connector 2, which accordingly includes obliquely rising projections 12.
Die Fig. 4 bis 6 zeigen in isolierten Darstellungen einen der erfindungsgemäßen Steckverbinder 4 mit den verdrillten Adern 5 (elektrisch leitfähiger Leiter und Isoliermantel) eines daran angeschlossenen Twisted-Pair-Kabels. Neben dem Gehäuse 7 umfasst der Steckverbinder 4 zwei Kontaktelemente 13, die in dem Gehäuse 7 (zumindest in Richtung ihrer Längsachsen) fixiert gelagert sind und steckseitige sowie kabelseitige Enden aufweisen. An den kabelseitigen Enden sind die Kontaktelemente 13 über Crimpverbindungen mit jeweils einem abisolierten Abschnitt eines der zwei Adern 5 des Twisted-Pair-Kabels verbunden. Die steckseitigen Enden sind dazu ausgebildet, komplementäre Kontaktelemente 14 des Leiterplattensteckverbinders 2 zu kontaktieren, wobei die buchsenförmigen Kontaktelemente 13 des Steckverbinders 4 stiftförmige Kontaktelemente 14 des Leiterplattensteckverbinders 2 aufnehmen und dabei radial elastisch aufgeweitet werden, was durch eine entsprechende Längsschlitzung möglich ist. 4 to 6 show in isolated representations of one of the connectors 4 according to the invention with the twisted wires 5 (electrically conductive conductor and insulating jacket) connected to a twisted pair cable. In addition to the housing 7, the connector 4 comprises two contact elements 13 which are mounted fixedly in the housing 7 (at least in the direction of their longitudinal axes) and have plug-side as well as cable-side ends. At the cable-side ends, the contact elements 13 are connected via crimped connections, each with a stripped section of one of the two wires 5 of the twisted pair cable. The plug-side ends are adapted to contact complementary contact elements 14 of the printed circuit board connector 2, wherein the sleeve-shaped contact elements 13 of the connector 4 record pin-shaped contact elements 14 of the printed circuit board connector 2 and thereby radially expanded radially, which is possible by a corresponding Längsschlitzung.
Die Lagefixierung der Kontaktelemente 13 in dem Gehäuse 7 wird durch jeweils einen umlaufenden Vorsprung 15 realisiert, der in einer umlaufenden Nut des Gehäuses 7 angeordnet ist. The fixing of the position of the contact elements 13 in the housing 7 is realized by a respective circumferential projection 15 which is arranged in a circumferential groove of the housing 7.
Das Gehäuse 7 des Steckverbinders 4 umfasst zwei Gehäuseteile 16, 17. Die Trennebene zwischen diesen Gehäuseteilen 16, 17 verläuft dabei parallel und insbesondere koplanar zu derjenigen Ebene, die von den Längsachsen der beiden Kontaktelemente 13 aufgespannt wird. Eine dauerhafte Verbindung zwischen den beiden Gehäuseteilen 16, 17 wird über zwei Rastlaschen 18 eines ersten (16) der Gehäuseteile realisiert, in deren Hinterschnitte (in Form von Durchgangsöffnungen 19) Vorsprünge 20 des zweiten (17) der Gehäuseteile eingreifen. Weiterhin dienen zwei Vorsprünge 21 des ersten Gehäuseteils 16, die in komplementäre Vertiefungen 22 des zweiten Gehäuseteils 17 eingreifen, einer zusätzlichen Lagesicherung der beiden Gehäuseteile 16, 17 zueinander. The housing 7 of the connector 4 comprises two housing parts 16, 17. The parting plane between these housing parts 16, 17 extends parallel and in particular coplanar to that plane which is spanned by the longitudinal axes of the two contact elements 13. A permanent connection between the two housing parts 16, 17 is realized via two latching lugs 18 of a first (16) of the housing parts, in whose undercuts (in the form of through openings 19) engage projections 20 of the second (17) of the housing parts. Furthermore, two projections 21 of the first housing part 16, which engage in complementary recesses 22 of the second housing part 17, an additional securing position of the two housing parts 16, 17 to each other.
Die Adern 5 des Twisted-Pair-Kabels weisen auch innerhalb des Gehäuses 7 des Steckverbinders 4 einen verdrillten Verlauf auf. Durch eine von dem Gehäuse 7 ausgebildete Führung für die Adern 5 wird dabei sichergestellt, dass die Verdrillung dauerhaft ist und sich nicht auflösen kann. Diese Führung wird von den Innenseiten eines von dem Gehäuse 7 ausgebildeten Führungsraums in Verbindung mit zwei Führungszapfen 23 erreicht, die sich in senkrechter Richtung bezogen auf die von den Längsachsen der beiden Kontaktelemente aufgespannten Ebene sowie mittig zwischen diesen beiden Längsachsen in dem Führungsraum erstrecken. Die Führungszapfen 23 sind dabei von dem zweiten Gehäuseteil 17 ausgebildet und greifen zur Stabilisierung in Vertiefungen 24 des ersten Gehäuseteils 16 ein. Die Adern 5 des Twisted-Pair-Kabels sind - in Fortsetzung der Verdrillung, in der diese innerhalb des Kabels geführt sind - bogenförmig um die Führungszapfen 23 geführt, umschlingen diese somit teilweise. Dabei kann auch vorgesehen sein, dass die Adern 5 zumindest abschnittsweise zwischen den Führungszapfen 23 und den Innenseiten des Führungsraums des Gehäuses 7 bzw. zwischen den Innenseiten des Gehäuses 7 und der jeweiligen anderen Ader 5 eingeklemmt sind. Dadurch können relativ hohe Zugbelastungen von dem Twisted-Pair-Kabel auf das Gehäuse 7 übertragen werden. Für die Crimpverbindungen zwischen den Adern 5 und den Kontaktelementen 13 wird somit eine Zugentlastung realisiert. The wires 5 of the twisted pair cable also have a twisted course within the housing 7 of the connector 4. By trained by the housing 7 guide for the wires 5 is thereby ensured that the twist is permanent and can not dissolve. This guide is achieved by the inner sides of a trained by the housing 7 guide space in conjunction with two guide pins 23 which extend in the vertical direction relative to the plane spanned by the longitudinal axes of the two contact elements level and centrally between these two longitudinal axes in the guide space. The guide pins 23 are formed by the second housing part 17 and engage in the recesses 24 of the first housing part 16 for stabilization. The wires 5 of the twisted pair cable are - in continuation of the twisting, in which they are guided within the cable - arcuately guided around the guide pin 23, thus wrap around this partially. It can also be provided that the wires 5 are at least partially clamped between the guide pin 23 and the inner sides of the guide space of the housing 7 and between the inner sides of the housing 7 and the respective other core 5. As a result, relatively high tensile loads can be transmitted from the twisted pair cable to the housing 7. For the crimp connections between the wires 5 and the contact elements 13, a strain relief is thus realized.
Die beiden Gehäuseteile 16, 17 des Steckverbinders 4 sind vollständig aus elektrisch nicht leitendem Kunststoff ausgebildet, wobei die einfache geometrische Form ein vorteilhaftes Spritzgießen ermöglicht. Bei einer Entformungsrichtung, die in Richtung der Längsachsen der Führungszapfen 23 ausgerichtet ist, weist lediglich die erste Gehäusehälfte 16 Hinterschnitte in Form der Durchgangsöffnungen 19 der Rastlaschen 18 auf. Da die Rastlaschen 18 funktional jedoch gerade elastisch auslenkbar ausgebildet sind, besteht die Möglichkeit, auch das erste Gehäuseteil 16 ohne den Einsatz von Schiebern oder Ähnlichem zu entformen. The two housing parts 16, 17 of the connector 4 are completely formed of electrically non-conductive plastic, the simple geometric shape allows advantageous injection molding. In a Entformungsrichtung, in the direction of the longitudinal axes of the guide pin 23rd is oriented, only the first housing half 16 has undercuts in the form of the through holes 19 of the locking tabs 18. Since the locking tabs 18 are functionally but just elastically deflectable formed, it is possible to remove the first housing part 16 without the use of slides or the like.
Eine separate Schirmung für den Steckverbinder 4 ist nicht vorgesehen. Infolge der bis zu den Kontaktelementen 13 fortgesetzten Verdrillung der Leiter 5 ist jedoch ein Übersprechen zwischen den in dem Mehrfach-Steckverbinder 1 kombinierten, einzelnen Steckverbindern 34 für viele Anwendungen hinreichend gering. A separate shield for the connector 4 is not provided. However, due to the continued twisting of the conductors 5 up to the contact elements 13, crosstalk between the individual connectors 34 combined in the multiple connector 1 is sufficiently low for many applications.
In den Fig. 7 bis 9 ist der Leiterplattensteckverbinder isoliert in verschiedenen perspektivischen Darstellungen dargestellt. Dieser umfasst das Gehäuse 11 mit einem Grundkörper 25 und einer Abdeckung 26. Der Grundkörper 25 bildet auf einer Seite ein Steckinterface, das komplementär zu einem von dem Mehrfach- Steckverbinder 1 ausgebildeten Steckinterface ist. Das Steckinterface des Leiterplattensteckverbinders 2 umfasst mehrere (konkret fünf) (Durchgangs- )Öffnungen 27, innerhalb denen jeweils zwei stiftförmige Kontaktelemente 14, d.h. ein Kontaktelementepaar, in paralleler Ausrichtung angeordnet sind. Diese kontaktieren im zusammengesteckten Zustand der Steckverbinder 1 , 2 die Kontaktelemente 13 des Mehrfachsteckverbinders 1. Der Querschnitt der Öffnungen 27 des Grundkörpers 25 ist länglich-oval und entspricht dem Querschnitt eines Steckabschnitts 28 der Gehäuse 7 der einzelnen Steckverbinder 4 des Mehrfachsteckverbinders 1. Der die Öffnungen umgebende (Steck-)Abschnitt 29 der Außenseite des Grundkörpers 25 weist eine komplexe Form auf, die komplementär zu der Innenseite eines Steckabschnitts 30 des Gehäuses 3 des Mehrfachsteckverbinders 1 ist. Somit greifen die Steckabschnitte 28 der einzelnen Steckverbinder 4 in die Öffnungen 27 des Grundkörpers 25 des Leiterplattensteckverbinders 2 und der Steckabschnitt 29 des Grundkörpers 25 des Leiterplattensteckverbinders 2 in den Steckabschnitt 30 des Gehäuses 3 des Mehrfachsteckverbinders 1 ein. In Verbindung mit der dauerhaften Fixierung durch die Rastlaschen 10 kann dadurch eine hohe mechanische Belastbarkeit der Steckverbindung erreicht werden. Die Kontaktelemente 14 des Leiterplattensteckverbinders 2 sind einstückig an den steckseitigen Enden von Leitern 31 ausgebildet, die in dem Grundkörper 25 zunächst noch eine definierte Distanz koaxial zu den Kontaktelementen 14 weiter verlaufen und dann um 90° abknicken. In den relativ zu den Kontaktelementen 14 abgewinkelten Abschnitten sind die Leiter 31 in schlitzförmigen Öffnungen 32 der Abdeckung 26 aufgenommen, wobei sie die Abdeckung 26 und somit das Gehäuse 11 des Leiterplattensteckverbinders 2 ein definiertes Maß überragen. Mit den überragenden Enden können die Leiter 31 entsprechende Kontaktstellen einer Leiterplatte (nicht dargestellt) kontaktieren, wobei diese vorzugsweise gleichzeitig in Öffnungen der Leiterplatte eingreifen, um den Leiterplattensteckverbinder 2 auch mechanisch mit der Leiterplatte zu verbinden. Zur weiteren mechanischen Stabilisierung dienen zwei zapfenförmige Vorsprünge 33, die in entsprechende Öffnungen der Leiterplatte eingreifen. In Figs. 7 to 9 of the printed circuit board connector is shown in isolation in various perspective views. This comprises the housing 11 with a base body 25 and a cover 26. The main body 25 forms on one side of a plug-in interface, which is complementary to a plug-in interface formed by the multiple connector 1. The plug-in interface of the printed circuit board connector 2 comprises a plurality (specifically five) (through) openings 27, within each of which two pin-shaped contact elements 14, ie a pair of contact elements, are arranged in parallel alignment. These contact in the assembled state of the connectors 1, 2, the contact elements 13 of the multiple connector 1. The cross section of the openings 27 of the body 25 is elongated-oval and corresponds to the cross section of a plug-in portion 28 of the housing 7 of the individual connector 4 of the multiple connector 1. The openings surrounding (plug) portion 29 of the outside of the main body 25 has a complex shape which is complementary to the inside of a plug-in portion 30 of the housing 3 of the multiple connector 1. Thus, the plug portions 28 of the individual connectors 4 engage in the openings 27 of the main body 25 of the printed circuit board connector 2 and the plug portion 29 of the main body 25 of the printed circuit board connector 2 in the plug portion 30 of the housing 3 of the multiple connector 1. In conjunction with the permanent fixation by the locking tabs 10, a high mechanical strength of the connector can be achieved. The contact elements 14 of the printed circuit board connector 2 are integrally formed on the plug-side ends of conductors 31 which extend in the main body 25 initially a defined distance coaxial with the contact elements 14 and then bend by 90 °. In the relative to the contact elements 14 angled portions, the conductors 31 are received in slot-shaped openings 32 of the cover 26, wherein they project beyond the cover 26 and thus the housing 11 of the printed circuit board connector 2 a defined extent. With the protruding ends of the conductors 31 corresponding contact points of a printed circuit board (not shown) contact, which preferably engage simultaneously in openings of the circuit board to mechanically connect the PCB connector 2 to the circuit board. For further mechanical stabilization serve two pin-shaped projections 33 which engage in corresponding openings of the circuit board.
Die Anordnung der Öffnungen 27 und damit auch der Kontaktelementepaare in dem Gehäuse 11 des Leiterplattensteckverbinders 2 ist zick-zack-förmig, d.h. drei der fünf Kontaktelementepaare sind in einer ersten Reihe und die zwei übrigen Kontaktelementepaare sind in einer dazu parallel beabstandeten, zweiten Reihe angeordnet. Dabei ist vorgesehen, dass der Abstand der zwei Kontaktelementepaare der zweiten Reihe zu den beiden jeweils benachbarten Kontaktelementepaaren der ersten Reihe im Wesentlichen gleich ist, diese somit mittig dazu liegen. Dadurch kann eine kompakte Anordnung der Kontaktelementepaare in dem Gehäuse 11 erreicht werden, wobei gleichzeitig ein möglichst großer Abstand zu benachbarten Kontaktelementepaaren eingehalten wird. Dadurch kann bereits geometrisch ein relativ geringes Übersprechen zwischen den Kontaktelementepaaren realisiert werden. The arrangement of the openings 27 and thus also the contact element pairs in the housing 11 of the printed circuit board connector 2 is zig-zag, i. three of the five pairs of contact elements are in a first row and the two remaining pairs of contact elements are arranged in a second row spaced parallel thereto. It is provided that the distance between the two pairs of contact elements of the second row to the two adjacent pairs of contact elements of the first row is substantially equal, they thus lie centrally to it. As a result, a compact arrangement of the contact element pairs in the housing 11 can be achieved, wherein at the same time the greatest possible distance to adjacent pairs of contact elements is maintained. As a result, a relatively low crosstalk between the contact element pairs can already be realized geometrically.
Dieses Übersprechen wird zudem durch ein Schirmungselement in Form eines Schirmungsblechs 34 reduziert, das in einer sich zwischen der ersten Reihe und der zweiten Reihe der Kontaktelementepaare erstreckenden, schlitzförmigen Aufnahme des Grundkörpers 25 angeordnet ist. Der Verlauf der Aufnahme und damit des Schirmungsblechs 34 ist dabei nicht eben, sondern - der Anordnung der Kontaktelementepaare entsprechend - zick-zack-förmig. Wie sich insbesondere aus der Fig. 9 ergibt, ist das Schirmungsblech 34 ebenfalls um 90° abgewinkelt und folgt dadurch dem Verlauf der Leiter 31. Dabei separiert der relativ zu den Kontaktelementen 14 abgewinkelt verlaufende Abschnitt des Schirmungsblechs 34 die entsprechenden Abschnitte der Leiter 31 in eine erste Reihe und eine zweite Reihe, wobei die Leiter 31 der ersten Reihe auch die Kontaktelemente 14 der ersten Reihe und die Leiter 31 der zweiten Reihe auch die Kontaktelemente 14 der zweiten Reihe ausbilden. Diese räumliche Anordnung der relativ zu den Kontaktelementen 14 abgewinkelten Abschnitte der Leiter 31 wird durch unterschiedliche Längen der Leiter 31 der ersten Reihe einerseits und der zweiten Reihe andererseits erreicht. This crosstalk is also reduced by a shielding element in the form of a Schirmungsblechs 34 which is arranged in a between the first row and the second row of the contact element pairs extending, slit-shaped receptacle of the main body 25. The course of the recording and thus the Schirmungsblechs 34 is not flat, but - the arrangement of the contact element pairs according to - zigzag-shaped. As is apparent in particular from FIG. 9, the shielding plate 34 is likewise angled at 90 ° and thus follows the course of the conductors 31. In this case, the section of the shielding plate 34 that runs at an angle relative to the contact elements 14 separates the corresponding sections of the conductors 31 into one first row and a second row, wherein the conductors 31 of the first row and the contact elements 14 of the first row and the conductors 31 of the second row also form the contact elements 14 of the second row. This spatial arrangement of the relative to the contact elements 14 angled portions of the conductors 31 is achieved by different lengths of the conductors 31 of the first row on the one hand and the second row on the other.
Das Schirmungsblech 34 bildet noch Kontaktlaschen aus, die zur Kontaktierung von Schirmungskontakten der Leiterplatte vorgesehen sind. The Schirmungsblech 34 still forms contact tabs, which are provided for contacting shield contacts of the circuit board.
Der Grundkörper 25 und die Abdeckung 26 des Leiterplattensteckverbinders 2 sind vollständig aus elektrisch nicht leitendem Kunststoff ausgebildet, wobei die geometrisch einfache Form beider Bauteile eine Herstellung durch Spritzgießen vereinfacht. Das um 90° abgewinkelte Schirmungsblech 34 weist ebenfalls eine geometrisch einfache Form auf, die eine einfache und kostengünstige Herstellung als Stanzbiegebauteil ermöglicht. The main body 25 and the cover 26 of the printed circuit board connector 2 are formed entirely of electrically non-conductive plastic, wherein the geometrically simple shape of both components simplifies production by injection molding. The angled by 90 ° Schirmungsblech 34 also has a geometrically simple shape, which allows a simple and cost-effective production as a stamped and bent component.
