Description

Die Erfindung betrifft einen Steckverbinder mit einem Gehäuse und einer Mehrzahl an in dem Gehäuse fixierten Kontaktelementepaaren, die in einem zusammengesteckten Zustand die Kontaktelemente eines weiteren Steckverbinders kontaktieren, wobei mindestens zwei Kontaktelementepaare benachbart in einer Reihe und mindestens ein weiteres Kontaktelementepaar beabstandet zu der Reihe angeordnet ist, wobei zwischen den zwei Kontaktelementepaaren der Reihe einerseits und dem weiteren Kontaktelementepaar andererseits ein Schirmungselement (34) angeordnet ist, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a connector having a housing and a plurality of contact element pairs fixed in the housing, which contact the contact elements of a further connector in a mated state, wherein at least two contact element pairs are arranged adjacent in a row and at least one further contact element pair spaced from the row, wherein between the two pairs of contact elements of the series on the one hand and the other pair of contact elements on the other hand, a shielding element (34) is arranged, according to the preamble of claim 1.

Der Steckverbinder ist für die Übertragung von Hochfrequenzsignalen (HF-Signalen) geeignet.The connector is suitable for the transmission of high frequency (RF) signals.

Ein Problem, das sich bei solchen Mehrfach-Steckverbindern stellt, ist, ein Übersprechen der mehreren Kontaktelementepaare mit einer damit einhergehenden Störung der Signalübertragung zu vermeiden. Hierzu ist es bekannt, in das Gehäuse des Steckverbinders eine Schirmung zu integrieren, wobei für das Erreichen einer guten Schirmungswirkung vorgesehen ist, jedes der Kontaktelementepaare vollumfänglich von der Schirmung zu umgeben. Eine solche Ausgestaltung eines Mehrfach-Steckverbinders führt jedoch zu relativ hohen Herstellungskosten.One problem that arises in such multiple connectors is to avoid crosstalk of the plurality of pairs of contact elements with concomitant interference with signal transmission. For this purpose, it is known to integrate a shield into the housing of the connector, wherein it is provided for achieving a good shielding effect, to surround each of the contact element pairs in full by the shield. However, such a configuration of a multiple connector leads to relatively high production costs.

Ein gattungsgemäßer Steckverbinder ist aus der WO 2012/041310 A1 bekannt. Hierbei sind zur Übertragung mehrerer unabhängiger, differentieller Signale paarweise angeordnete elektrische Kontakte in dem Steckverbinder angeordnet. Eine kreuzförmige Struktur in Form eines elektrisch leitenden Schirmkreuzes isoliert die elektrischen Kontaktpaare voneinander. Das elektrisch leitende Schirmkreuz ist von einem ebenfalls kreuzförmigen Kontaktträger umgeben, in dessen schräg ausgebildeten Innenkanten Aufnahmerillen zum Halten der elektrischen Kontakte vorgesehen sind. Über diese kreuzförmige Anordnung wird ein elektrisch nicht leitender Rundkörper geschoben, der letztlich wiederum von einem elektrisch leitenden Gehäuse umgeben ist. Mittels einer an dem Rundkörper angefügten Positionierhilfe werden Anschlussenden der elektrischen Kontakte exakt auf einer Leiterplatte ausgerichtet. Dabei weist die Positionierhilfe entsprechende Bohrungen für die Anschlussenden der elektrischen Kontakte auf, die mit Lötbohrungen auf der Leiterplatte übereinstimmen.A generic connector is from the WO 2012/041310 A1 known. In this case, paired electrical contacts are arranged in the connector for transmitting a plurality of independent, differential signals. A cross-shaped structure in the form of an electrically conductive shield cross isolates the electrical contact pairs from each other. The electrically conductive shield cross is surrounded by a likewise cross-shaped contact carrier, are provided in the obliquely formed inner edges receiving grooves for holding the electrical contacts. About this cross-shaped arrangement, an electrically non-conductive round body is pushed, which in turn is in turn surrounded by an electrically conductive housing. By means of an attached to the round body positioning help terminal ends of the electrical contacts are aligned exactly on a circuit board. In this case, the positioning aid has corresponding holes for the terminal ends of the electrical contacts, which coincide with solder holes on the circuit board.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, einen Steckverbinder anzugeben, der bei weiterhin guten Übertragungseigenschaften für HF-Signale besonders kostengünstig herstellbar ist.Based on this prior art, the present invention seeks to provide a connector that is particularly inexpensive to produce with good transmission properties for RF signals.

Diese Aufgabe wird durch einen Steckverbinder gemäß dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Steckverbinders sind Gegenstand der abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by a connector according to the independent claim 1. Advantageous embodiments of the connector 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 gattungsgemäßen Steckverbinder durch eine vorteilhafte Anordnung der Kontaktelementepaare in dem Gehäuse zu reduzieren, wobei die Anordnung ein Übersprechen zwischen den Kontaktelementepaaren möglichst gering halten, eine möglichst einfache geometrische Form des Gehäuses sicherstellen und zudem ermöglichen soll, durch die Verwendung von lediglich einem möglichst einfach ausgebildeten Schirmungselement ein Übersprechen zwischen den Kontaktelementen gering zu halten.The invention is based on the idea to reduce the manufacturing cost of a generic connector by an advantageous arrangement of the contact element pairs in the housing, the arrangement to minimize crosstalk between the pairs of contact elements, ensure the simplest possible geometric shape of the housing and also allow through the use of only one simple trained shielding a To keep crosstalk between the contact elements low.

Konstruktiv umgesetzt wird dieser Erfindungsgedanke dadurch, dass das weitere Kontaktelementepaar (14) zu den zwei Kontaktelementepaaren (14) der Reihe, die die nächst benachbarten Kontaktelementepaare (14) sind, einen identischen Abstand hat, so dass die Anordnung der Kontaktelementepaare (14) in dem Gehäuse (11) des Steckverbinders (2) zick-zack-förmig ist, wobei der Verlauf des Schirmungselementes (34) der Anordnung der Kontaktelementepaare (14) entsprechen zick-zack-förmig ist. Sofern mehrere zu der (ersten) Reihe beabstandete Kontaktelementepaare vorgesehen sind, sind diese vorzugsweise in einer zweiten, zu der ersten parallel beabstandeten Reihe angeordnet und zu den nächst beabstandeten Kontaktelementepaaren der ersten Reihe ist der Abstand jeweils im Wesentlichen identisch.This concept of the invention is implemented constructively in that the further pair of contact elements (14) have an identical spacing from the two contact element pairs (14) of the row, which are the next adjacent contact element pairs (14), so that the arrangement of the contact element pairs (14) in the Housing (11) of the connector (2) is zigzag-shaped, wherein the course of the Schirmungselementes (34) of the arrangement of the contact element pairs (14) correspond to zig-zag-shaped. If a plurality of contact element pairs spaced apart from the (first) row are provided, these are preferably arranged in a second row spaced parallel to the first, and the spacing to the next-spaced pair of contact elements of the first row is substantially identical in each case.

Durch die erfindungsgemäße zick-zack-förmige Anordnung der Kontaktelementepaare kann erreicht werden, dass bei einem vorgegebenen Bauraum der Abstand zwischen allen benachbarten Kontaktelementepaaren möglichst groß ist. Dadurch kann ein Übersprechen zwischen den einzelnen Kontaktelementepaaren bereits relativ gering gehalten werden. Verbessert wird diese noch durch die Anordnung des Schirmungselements (z.B. Schirmungsblech) zwischen der (ersten) Reihe der Kontaktelementepaare und dem weiteren Kontaktelementepaar bzw. zwischen den zwei Reihen der Kontaktelementepaare. Das Schirmungselement, das vorzugsweise keines der Kontaktelementepaare vollumfänglich (bezüglich einer Steckrichtung der einzelnen Kontaktelemente) umgibt, kann dadurch geometrisch einfach ausgestaltet sein und kann dennoch in Verbindung mit der erfindungsgemäßen Anordnung der Kontaktelementepaare eine ausreichend gute Schirmungswirkung bewirken.The inventive zig-zag-shaped arrangement of the contact element pairs can be achieved that, for a given space, the distance between all adjacent pairs of contact elements is as large as possible. As a result, crosstalk between the individual pairs of contact elements can already be kept relatively low. This is further enhanced by the arrangement of the shielding element (e.g., shielding plate) between the (first) row of contact element pairs and the further pair of contact elements, or between the two rows of contact element pairs. The shielding element, which preferably surrounds none of the contact element pairs in their entirety (with respect to a plugging direction of the individual contact elements), can thereby be configured geometrically simple and yet, in conjunction with the inventive arrangement of the contact element pairs, can produce a sufficiently good shielding effect.

Die erfindungsgemäße Anordnung der für die Signalübertragung vorgesehenen Elemente kann vorzugsweise im gesamten Gehäuse des Steckverbinders vorgesehen sein, so dass auch Leiter, die mit den einzelnen Kontaktelementen verbunden sind, vorzugsweise in der entsprechenden Anordnung in einer (ersten) Reihe und beabstandet dazu (ggf. in einer zweiten Reihe) angeordnet sind. Bei diesen Leitern kann es sich z.B. um Leiter von Kabeln (insbesondere Twisted-Pair-Kabel) handeln, die mit den Kontaktelementen elektrisch leitend verbunden sind. Ebenso können auch Leiter in das Gehäuse integriert sein, die z.B. mit ihrem freien Ende ein Stück weit aus dem Gehäuse herausragen. Ein solcher Steckverbinder eignet sich dann besonders zur Verbindung mit einer Leiterplatte, wobei die freien Enden der Leiter dann entsprechende Kontaktstellen der Leiterplatte kontaktieren. In diesem Fall kann der erfindungsgemäße Steckverbinder dazu dienen, eine Mehrzahl an Kabeln, die mit zu den Kontaktelementen des Steckverbinders komplementären Kontaktelementen verbunden sind, an eine Leiterplatte anzubinden.The arrangement according to the invention of the elements provided for the signal transmission may preferably be provided in the entire housing of the connector, so that also conductors which are connected to the individual contact elements, preferably in the corresponding Arrangement in a (first) row and spaced therefrom (possibly in a second row) are arranged. These conductors can be, for example, conductors of cables (in particular twisted pair cables) which are electrically conductively connected to the contact elements. Likewise, conductors can also be integrated into the housing, which for example protrude a little way out of the housing with their free end. Such a connector is then particularly suitable for connection to a printed circuit board, wherein the free ends of the conductor then contact corresponding contact points of the circuit board. In this case, the connector according to the invention can serve to connect a plurality of cables, which are connected to the contact elements of the connector complementary contact elements, to a circuit board.

Hierbei kann auch vorgesehen sein, dass die Leiter in dem Gehäuse abgewinkelt verlaufen. Dann ist vorzugsweise vorgesehen, dass (auch) zwischen den relativ zu den Kontaktelementen abgewinkelten Abschnitten der Leiter der (ersten) Reihe und dem/den entsprechenden Abschnitt(en) des/der zu der (ersten) Reihe beabstandeten Leiter(s) (der zweiten Reihe) ein Schirmungselement angeordnet ist. Das Schirmungselement kann dadurch entsprechend dem zwischen den Kontaktelementepaaren der (ersten) Reihe und den dazu beabstandet angeordneten Kontaktelementepaaren vorgesehenen Schirmungselement ausgebildet sein. Auch besteht die Möglichkeit, beide Schirmungselemente einstückig, z.B. als abgewinkeltes Schirmungsblech auszubilden.It can also be provided that the conductors extend angled in the housing. Then, it is preferably provided that between the sections of the (first) row and the corresponding section (s) of the section (s) spaced apart from the contact elements (also), the second section (s) (2) are spaced apart Row) a shielding element is arranged. The shielding element can thereby be configured in accordance with the shielding element provided between the pairs of contact elements of the (first) row and the pair of contact elements arranged at a distance therefrom. It is also possible to integrate both shielding elements in one piece, e.g. as an angled shielding sheet form.

Individual parts of the PCB connector in a perspective view.

Die Fig. 1 und 2 zeigen eine Steckverbindung aus einem erfindungsgemäßen (Mehrfach-)Leiterplattensteckverbinder 2 und einem als Gegensteckverbinder dazu dienenden Mehrfachsteckverbinder 1.The Fig. 1 and 2 show a plug-in connection of a (multiple) printed circuit board connector 2 according to the invention and a multiple connector 1 serving as mating connector.

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 portions of the wires 5 are shown) is plugged in and there secured in position via a latching connection. The latching 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.The 4 to 6 show in isolated representations 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.The housing 7 of the connector 4 comprises two housing parts 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 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 off formed electrically non-conductive plastic, the simple geometric shape allows advantageous injection molding. In a demolding direction, which is aligned in the direction of the longitudinal axes of the guide pin 23, only the first housing half 16 has undercuts in the form of the passage openings 19 of the latching 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.In the Fig. 7 to 9 the printed circuit board connector is shown isolated 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 sections 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 body 25 of the printed circuit board connector 2 in the plug portion 30 of the housing 3 of the multiple connector 1 a. In conjunction with the permanent fixation by the locking tabs 10, a high mechanical strength of the connector can be achieved.

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.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 zigzag-shaped, ie three of the five contact element pairs are in a first row and the two remaining contact element pairs 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.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.

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.As can be seen in particular from the Fig. 9 In this case, the Schirmungsblech 34 is also angled at 90 °, thereby following the course of the conductor 31. In this case, the relative to the contact elements 14 angled extending portion of the Schirmungsblechs 34 separates the corresponding sections of the conductors 31 in a first row and a second row, wherein the conductors 31 of the first row also form 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.
