Description

System mit mehreren Steckverbindern und Mehrfachsteckverbinder  System with multiple connectors and multiple connectors
Die Erfindung betrifft ein System mit mehreren, sich hinsichtlich ihrer Außenform unterscheidenden Steckverbindern sowie einen ein solches System aufweisenden Mehrfachsteckverbinder. Die Steckverbinder sind insbesondere für eine Verbindung mit Twisted-Pair-Kabeln und zur Übertragung von Hochfrequenzsignalen vorgesehen. The invention relates to a system having a plurality of connectors which differ in terms of their external shape and to a multiple connector having such a system. The connectors are especially designed for connection to twisted-pair cables and to transmit high-frequency signals.
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 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 (ie the conductor of the cable surrounded by an insulating jacket) are twisted together in pairs twisted wire pairs better protection against external alternating magnetic fields and electrostatic interference, since in a symmetrical signal transmission by twisting the wire pairs, the influences 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. Bei der Verbindung eines Twisted-Pair-Kabels mit einem konventionellen Steckverbinder ist vorgesehen, den äußeren, die Adern umgebenden Kabelmantel in einem Abschnitt zu entfernen. Dann werden die zusätzlich von ihrem Isoliermantel befreiten Enden der Adern mit Kontaktelementen des Steckverbinders dauerhaft verbunden. Die Kontaktelemente sind wiederum in dem Gehäuse des Steckverbinders 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. Connectors are used to electrically connect electrically conductive components, such as cables. When connecting a twisted pair cable to a conventional connector, it is intended to remove the outer cable sheath surrounding the wires in one section. Then the additionally freed of their insulating ends of the wires are permanently connected to contact elements of the connector. The contact elements are in turn fixed in the housing of the connector. 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.
Bekannt ist weiterhin eine Serie von Steckverbindern, die sich durch ein im Wesentlichen einheitliches Steckinterface auszeichnen, derart abzuwandeln, dass diese nur mit dazu passenden Gegensteckverbindern verbunden werden können. Derartige Kodierungen für die Steckverbinder können beispielsweise in Form von einfachen Vorsprüngen vorgesehen sein, die sich bei den verschiedenen Steckverbindern hinsichtlich der Anordnung an den Gehäusen und/oder in ihren Abmessungen unterscheiden und in entsprechend angeordnete und/oder dimensionierte Vertiefungen der passenden Gegensteckverbinder eingreifen. Also known is a series of connectors, which are characterized by a substantially uniform plug-in interface, to modify such that they can only be connected to matching mating connectors. Such codes for the connectors may be provided, for example in the form of simple projections, which differ in the various connectors with respect to the arrangement of the housings and / or in their dimensions and engage in correspondingly arranged and / or dimensioned recesses of the matching mating connector.
Nachteilig an einer in die Gehäuse der Steckverbinder integrierten Kodierung ist, dass dadurch die Kosten für die Herstellung der Steckverbinder erhöht werden. Dies gilt insbesondere, wenn die Gehäuse der Steckverbinder mittels Kunststoff- Spritzgießens hergestellt werden, da die unterschiedlichen Kodierungen unterschiedliche Spritzgießwerkzeuge erforderlich machen. Zudem kann eine große Zahl unterschiedlicher Formen für Gehäuseteile von Steckverbindern zu hohen Lagerhaltungskosten im Rahmen der Montage der Steckverbinder führen. Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, eine Möglichkeit anzugeben, mehrere sich hinsichtlich der Form ihres Gehäuses unterscheidende Steckverbindern kostengünstig herzustellen. Diese Aufgabe wird durch ein System mit mehreren Steckverbindern gemäß dem unabhängigen Anspruch 1 gelöst. Ein ein solches System umfassender Mehrfachsteckverbinder ist Gegenstand des unabhängigen Anspruchs 4. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Systems und des erfindungsgemäßen Mehrfachsteckverbinders sind Gegenstand der jeweiligen abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung. A disadvantage of an integrated into the housing of the connector coding that thereby the cost of producing the connector can be increased. This is especially true when the housing of the connector are manufactured by means of plastic injection molding, since the different codes make different injection molds required. In addition, a large number of different shapes for housing parts of connectors can lead to high storage costs in the context of mounting the connector. Based on this prior art, the present invention seeks to provide a way to produce several cheaper in terms of the shape of their housing connectors. This object is achieved by a system with a plurality of connectors according to independent claim 1. Advantageous embodiments of the system according to the invention and of the multiple plug connector according to the invention are the subject of the respective dependent claims and will become apparent from the following description of the invention.
Ein erfindungsgemäßes System mit mehreren, sich hinsichtlich der Form ihrer Gehäuse unterscheidenden Steckverbindern, ist dadurch gekennzeichnet, dass die Gehäuse der Steckverbinder mehrteilig ausgebildet sind, wobei diese erste Gehäuseteile, die zumindest hinsichtlich der Schnittstellen zu den weiteren Komponenten des jeweiligen Steckverbinders und besonders bevorzugt vollständig identisch sind, und unterschiedliche zweite Gehäuseteile aufweisen. Unter„mehrteilig" wird dabei verstanden, dass die Gehäuse aus mindestens zwei separaten Gehäuseteilen ausgebildet sind, die bei der Montage des Steckverbinders direkt oder indirekt miteinander verbunden werden. A system according to the invention with a plurality of connectors differing in the shape of their housings is characterized in that the housings of the connectors are designed in several parts, these first housing parts being completely identical at least with regard to the interfaces to the further components of the respective connector are, and have different second housing parts. The term "multi-part" is understood to mean that the housings are formed from at least two separate housing parts, which are connected directly or indirectly to one another during assembly of the connector.
Unter„identisch" wird dabei verstanden, dass die entsprechenden Elemente form- und abmessungsgleich sind. Unterschiede, z.B. hinsichtlich des Materials, sollen erfindungsgemäß möglich sein. The term "identical" is understood to mean that the corresponding elements have the same shape and dimensions, and that differences, for example as regards the material, should be possible according to the invention.
Als„Schnittstellen" werden dabei die Bereiche der ersten Gehäuseteile verstanden, die die anderen Komponenten des jeweiligen Steckverbinders (insbesondere dem zweiten Gehäuseteil und dem oder den Kontaktelementen) berühren. In this case, "interfaces" are understood to be the regions of the first housing parts which touch the other components of the respective connector (in particular the second housing part and the contact element or elements).
Bevorzugt ist demnach vorgesehen, dass die Formunterschiede der Gehäuse der verschiedenen Steckverbinder auf einen bestimmten Bereich, den zweiten Gehäuseteil, konzentriert werden, wodurch die Gehäuse im Übrigen, d.h. hinsichtlich des ersten Gehäuseteils, identisch ausgebildet werden können. Durch die Verwendung identischer erster Gehäuseteile für die Steckverbinder kann die Gesamtanzahl an Gehäusebauteilen, die für die Ausbildung der unterschiedlichen Steckverbinder benötigt werden, klein und damit Lagerhaltungskosten gering gehalten werden. Zudem kann die Anzahl der für die Herstellung der Gehäusebauteile benötigten Werkzeuge, insbesondere Spritzgießformen, gering gehalten werden, was sich ebenfalls positiv auf die Herstellungskosten auswirken kann. Auch kann sich dadurch eine automatisierte Konfektionierung der Steckverbinder mit daran zu befestigenden Kabeln vereinfachen. Preferably, it is accordingly provided that the shape differences of the housings of the various connectors are concentrated to a specific area, the second housing part, whereby the housings, moreover, ie with regard to of the first housing part, can be made identical. By using identical first housing parts for the connectors, the total number of housing components, which are required for the formation of different connectors, small and thus storage costs can be kept low. In addition, the number of tools required for the production of the housing components, in particular injection molds, can be kept low, which can also have a positive effect on the manufacturing costs. This can also simplify automated assembly of the connectors with cables to be fastened thereto.
Die Steckverbinder des erfindungsgemäßen Systems weisen neben dem Gehäuse zudem noch mindestens ein Kontaktelement auf, das zumindest teilweise innerhalb des Gehäuse (insbesondere fixiert) angeordnet ist und ein steckseitiges Ende aufweist, das zur Kontaktierung eines Gegenkontaktelements eines Gegensteckverbinders für den jeweiligen Steckverbinder vorgesehen ist. The connectors of the system according to the invention also have in addition to the housing at least one contact element which is at least partially within the housing (in particular fixed) and has a plug-side end which is provided for contacting a mating contact element of a mating connector for the respective connector.
Die Steckverbinder sind vorzugsweise jeweils zur Übertragung von Hochfrequenzsignalen vorgesehen. Daher weisen die Steckverbinder auch vorzugsweise jeweils mindestens zwei Kontaktelemente auf. Derartige Steckverbinder eignen sich für einen Anschluss an zwei Adern eines Twisted-Pair- Kabels. Die Kontaktelemente sind daher vorzugsweise noch dadurch gekennzeichnet, dass diese jeweils ein kabelseitiges Ende aufweisen, das zur Verbindung mit einer Ader eines Kabels vorgesehen und dementsprechend (z.B. durch das Vorsehen von Crimplaschen) ausgebildet ist. The connectors are preferably each provided for the transmission of high-frequency signals. Therefore, the connectors also preferably each have at least two contact elements. Such connectors are suitable for connection to two wires of a twisted pair cable. The contact elements are therefore preferably further characterized in that they each have a cable-side end, which is provided for connection to a wire of a cable and accordingly (for example by the provision of Crimplaschen) is formed.
Um eine einfache Montage der unterschiedlichen Steckverbinder zu ermöglichen kann vorzugsweise vorgesehen sein, dass die zweiten Gehäuseteile identische Verbindungsmittel zur Verbindung mit dem ersten Gehäuseteil aufweisen. Diese Verbindungmittel können insbesondere derart ausgebildet sein, dass diese eine kraftschlüssige (klemmende) und/oder formschlüssige Verbindung zwischen den Gehäuseteile bewirken. Formschlüssige Verbindungen können insbesondere als Rastverbindungen ausgebildet sein, die durch das federbelastete Eingreifen von Vorsprüngen in Vertiefungen gekennzeichnet sind. Die Herstellung und insbesondere die Montage der Steckverbinder des erfindungsgemäßen Systems kann dadurch vereinfacht werden, dass das oder die Kontaktelemente jedes Steckverbinders jeweils in dem ersten Gehäuseteil angeordnet und insbesondere auch darin fixiert sind. Eine Fixierung der Kontaktelemente kann insbesondere mittels Rastverbindungen erfolgen. In order to enable a simple assembly of the different connectors can preferably be provided that the second housing parts have identical connection means for connection to the first housing part. This connection means may in particular be designed such that they bring about a frictional (clamping) and / or positive connection between the housing parts. Positive connections may be formed in particular as snap-in connections, which are characterized by the spring-loaded engagement of projections in recesses. The production and in particular the assembly of the connector of the system according to the invention can be simplified in that the one or more contact elements of each connector are respectively arranged in the first housing part and in particular also fixed therein. A fixation of the contact elements can be effected in particular by means of latching connections.
Das erfindungsgemäße System eignet sich vorteilhaft zur Ausbildung eines Mehrfachsteckverbinder, bei dem die mehreren Steckverbinder des Systems in oder an einem Mehrfachgehäuse angeordnet und insbesondere fixiert sind. Dabei kann besonders bevorzugt vorgesehen sein, dass die zweiten Gehäuseteile zumindest einiger, vorzugsweise aller Steckverbinder unterschiedliche Kodierungen aufweisen, durch die den einzelnen Steckverbindern individuelle Positionen an oder in dem Mehrfachgehäuse zugeordnet sind. The system according to the invention is advantageously suitable for forming a multiple connector, in which the plurality of connectors of the system are arranged in or on a multiple housing and in particular fixed. It can be particularly preferably provided that the second housing parts of at least some, preferably all connectors have different codes, which are assigned to the individual connectors individual positions on or in the multiple housing.

Die Fig. 1 zeigt eine Steckverbindung aus einem erfindungsgemäßen Mehrfachsteckverbinder 1 und einem als Gegensteckverbinder dienenden (Mehrfach-)Leiterplattensteckverbinder 2. 1 shows a plug-in connection from a multiple plug-in connector 1 according to the invention and a (multiple) printed-circuit board connector 2 serving as mating connector.
Der Mehrfachsteckverbinder 1 umfasst ein Mehrfachgehäuse 3 mit einer Mehrzahl (im vorliegenden Ausführungsbeispiel insgesamt fünf) parallel angeordneten Aufnahmeöffnungen 4. In diese Aufnahmeöffnungen 4 ist jeweils ein erfindungsgemäßer Steckverbinder 5 eingesteckt und dort über eine Rastverbindung lagegesichert. Die Rastverbindungen umfassen Vorsprünge 6, die auf den Außenseiten von Gehäusen der Steckverbinder 5 ausgebildet sind, sowie Hinterschnitte in Form von Durchgangsöffnung, die von Rastlaschen 7 des Mehrfachgehäuses 3 ausgebildet sind. Beim Einstecken der Steckverbinder 5 in die Aufnahmeöffnungen 4 lenken die bezüglich der Einsteckrichtung schräg ansteigenden Vorsprünge 6 die Rastlaschen 7 aus, bis die Vorsprünge 6 in die Durchgangsöffnungen der Rastlaschen 7 eingreifen. Zum Lösen der Rastverbindungen können die Rastlaschen 7 manuell angehoben und dadurch aus dem Eingriff mit den Vorsprüngen 6 gebracht werden. The multiple connector 1 comprises a multiple housing 3 with a plurality (in the present embodiment, a total of five) arranged in parallel receiving openings 4. In these receiving openings 4, an inventive connector 5 is inserted in each case and there secured in position via a latching connection. The snap-in connections comprise projections 6, which are formed on the outer sides of housings of the plug-in connector 5, as well as undercuts in the form of through-openings, which are formed by latching tabs 7 of the multiple housing 3. When inserting the connector 5 in the receiving openings 4 with respect to the insertion obliquely rising projections 6 deflect the locking tabs 7, until the projections 6 engage in the through holes of the locking tabs 7. To release the locking connections, the locking tabs 7 can be raised manually and thereby brought out of engagement with the projections 6.
Das Mehrfachgehäuse 3 umfasst weiterhin eine mittige Rastlasche 8, die zur Ausbildung einer Rastverbindung mit einem Gehäuse 9 des Leiterplattensteckverbinders 2 vorgesehen ist, das dazu einen in Einsteckrichtung schräg ansteigenden Vorsprung 10 umfasst. Die Fig. 6 bis 8 zeigen die Steckverbinder 5 in der Anordnung, die diese innerhalb des Mehrfachgehäuses 3 aufweisen. Dabei sind drei der fünf Steckverbinder 5 in einer ersten Reihe und die zwei übrigen Steckverbinder 5 in einer dazu parallelen zweiten Reihe angeordnet. Dabei ist vorgesehen, dass der Abstand der Steckverbinder 5 der zweiten Reihe zu den beiden jeweils benachbarten Steckverbindern 5 der ersten Reihe im Wesentlichen gleich ist, diese somit mittig dazu angeordnet sind. Dadurch kann eine kompakte Anordnung der Steckverbinder 5 in dem Mehrfachgehäuse 3 erreicht werden, wobei gleichzeitig ein möglichst großer Abstand zu benachbarten Steckverbindern 5 eingehalten wird. Dadurch kann ein Übersprechen zwischen den Steckverbindern 5 gering gehalten werden. The multiple housing 3 further comprises a central locking tab 8, the Forming a latching connection is provided with a housing 9 of the printed circuit board connector 2, which includes a projection 10 rising obliquely in the insertion direction. FIGS. 6 to 8 show the connectors 5 in the arrangement which have these within the multiple housing 3. In this case, three of the five connectors 5 are arranged in a first row and the two remaining connectors 5 in a second row parallel thereto. It is provided that the distance of the connector 5 of the second row to the two respectively adjacent connectors 5 of the first row is substantially equal, they are thus arranged centrally to it. Thereby, a compact arrangement of the connector 5 can be achieved in the multiple housing 3, wherein at the same time the greatest possible distance to adjacent connectors 5 is maintained. As a result, a crosstalk between the connectors 5 can be kept low.
Neben der Lagesicherung der Steckverbinder 5 in dem Mehrfachgehäuse 3 mittels der Rastverbindungen sind diese noch über ein bügeiförmiges Sicherungselement 1 1 in dem Mehrfachgehäuse 3 gesichert. Das Sicherungselement 1 1 wird quer zur Einsteckrichtung in das Mehrfachgehäuse 3 gesteckt, wobei Stege des Befestigungselements 1 1 in die Aufnahmeöffnungen 4 ragen. Dabei greifen dieIn addition to securing the position of the connector 5 in the multiple housing 3 by means of the snap-in connections, these are still secured in the multiple housing 3 via a bow-shaped securing element 11. The fuse element 1 1 is inserted transversely to the insertion in the multiple housing 3, wherein webs of the fastener 1 1 protrude into the receiving openings 4. In doing so, the
Stege in Vertiefungen 12 der Gehäuse der drei in einer Reihe angeordneten Steckverbinder 5 ein, wodurch formschlüssige Lagesicherungen bezüglich der Einsteckrichtung ausgebildet werden. Die zwei in einer Reihe angeordneten Steckverbinder 5 werden entsprechend lagegesichert, indem die Stege zwischen Vorsprüngen 29 der Gehäuse angeordnet sind. Webs in recesses 12 of the housing of the three arranged in a row connector 5, whereby form-fitting position fuses are formed with respect to the insertion direction. The two arranged in a row connector 5 are secured in position accordingly by the webs between projections 29 of the housing are arranged.
Die Steckverbinder 5 stellen ein erfindungsgemäßes System dar und unterscheiden sich geringfügig in der äußeren Gehäuseform. Dies dient dazu, eine Kodierung für die individuelle Positionierung der einzelnen Steckverbinder 5 in dem Mehrfachgehäuse 3 auszubilden. Dazu weisen die Gehäuse der Steckverbinder 5 in Längsrichtung verlaufende Vertiefungen 13 auf, die bei den Steckverbindern 5 unterschiedlich positioniert und/oder dimensioniert sind. Beim Einschieben der Steckverbinder 5 in die jeweils dazugehörigen Aufnahmeöffnungen 4 des Mehrfachgehäuses 3 gleiten Vorsprünge 14 des Mehrfachgehäuses 3 in die Vertiefungen 13. Bei einem Einschieben der Steckverbinder 5 in falsche Aufnahmeöffnungen 4 ist dies infolge einer Kollision mit den Vorsprüngen 14 nicht bis in die durch die Rastverbindungen gesicherten Endstellungen möglich. Die Gehäuse der Steckverbinder 5 sind zweiteilig ausgeführt. Ein ersterThe connectors 5 represent a system according to the invention and differ slightly in the outer housing form. This serves to form a coding for the individual positioning of the individual connectors 5 in the multiple housing 3. For this purpose, the housing of the connector 5 in the longitudinal direction recesses 13 which are positioned differently and / or dimensioned in the connectors 5. When inserting the connector 5 in the respectively associated receiving openings 4 of the multiple housing 3 slide projections 14 of the multiple housing 3 in the Recesses 13. When inserting the connector 5 in wrong receiving openings 4 this is not possible due to a collision with the projections 14 into the secured by the locking connections end positions. The housing of the connector 5 are made in two parts. A first
Gehäuseteil 15 ist für alle Steckverbinder 5 identisch ausgebildet, während sich die zweiten Gehäuseteile 16 (lediglich) bezüglich der Integration der die Kodierung ausbildenden Vertiefungen 13 unterscheiden. Die Fig. 10 zeigt einen ersten Gehäuseteil 15. Die Fig. 9 zeigt einen zweiten Gehäuseteil auf der die Innenseite des entsprechenden Gehäuses ausbildenden Seite. Auf dieser Seite sind die zweiten Gehäuseteile 16 aller Steckverbinder 5 identisch ausgebildet. Housing part 15 is identical for all connectors 5, while the second housing parts 16 differ (only) with respect to the integration of the coding forming depressions 13. FIG. 10 shows a first housing part 15. FIG. 9 shows a second housing part on the side forming the inside of the corresponding housing. On this page, the second housing parts 16 of all connectors 5 are identical.
Neben dem Gehäuse umfassen die Steckverbinder 5 jeweils zwei Kontaktelemente 17, die innerhalb des Gehäuses fixiert gelagert sind und steckseitige sowie kabelseitige Enden aufweisen. An den kabelseitigen Enden können die Kontaktelemente 17 mittels Crimpverbindungen mit Adern eines (Twisted-Pair- )Kabels (nicht dargestellt) verbunden werden. Die steckseitigen Enden sind dazu ausgebildet, komplementäre Kontaktelemente 18 des Leiterplattensteckverbinders 2 zu kontaktieren, wobei die buchsenförmigen Kontaktelemente 17 der Steckverbinder 5 stiftförmige Kontaktelemente 18 des Leiterplattensteckverbinders 2 aufnehmen und dabei radial elastisch aufgeweitet werden, was durch eine entsprechende Längsschlitzung möglich ist. In addition to the housing, the plug connectors 5 each comprise two contact elements 17, which are mounted fixed inside the housing and have plug-side as well as cable-side ends. At the cable-side ends, the contact elements 17 can be connected by means of crimp connections to wires of a (twisted pair) cable (not shown). The plug-side ends are adapted to contact complementary contact elements 18 of the printed circuit board connector 2, wherein the female contact elements 17 of the connector 5 record pin-shaped contact elements 18 of the PCB connector 2 and thereby radially expanded radially, which is possible by a corresponding longitudinal slot.
Die Lagefixierung der Kontaktelemente 17 in den Gehäusen wird durch umlaufende Vorsprünge der Kontaktelemente 17 realisiert, die in umlaufenden Nuten derThe fixing of the position of the contact elements 17 in the housings is realized by circumferential projections of the contact elements 17, which in circumferential grooves of the
Gehäuses angeordnet sind. Housing are arranged.
Die beiden Gehäuseteile 15, 16 der Steckverbinder 5 umfassen jeweils einen steckseitigen Abschnitt, in dem im montierten Zustand der Steckverbinder 5 die Kontaktelemente 17 angeordnet sind. In diesem Abschnitt verläuft die Trennebene zwischen den Gehäuseteilen 15, 16 koplanar zu derjenigen Ebene, die von den Längsachsen der beiden (mit Ausnahme der Crimpverbindungen kreis- oder ringförmige Querschnitte aufweisenden) Kontaktelemente 17 aufgespannt wird. Weiterhin umfasst jeder Gehäuseteil 5, 16 einen kabelseitigen Abschnitt, der zur Aufnahme eines in dem Gehäuse aufgenommenen Abschnitts des Kabels vorgesehen ist. In diesem Abschnitt verläuft die Trennebene parallel zu der von den Längsachsen der beiden Kontaktelemente 17 aufgespannten Ebene. In dem jeweiligen kabelseitigen Abschnitt bilden beide Gehäuseteile 15, 16 an die Trennebene angrenzend jeweils vier Vorsprünge 19 aus, wobei jeweils zwei Vorsprünge 19 in Längsrichtung des Steckverbinders 5 voneinander beabstandet auf jeder Seite beider Gehäuseteile 15, 16 angeordnet sind. Die jeweils zwei Vorsprünge 19 bilden weiterhin eine Begrenzung für eine sich in Längsrichtung erstreckende Vertiefung 20 auf jeder Seite beider Gehäuseteile 15, 16 aus. The two housing parts 15, 16 of the connector 5 each comprise a plug-side section, in which in the assembled state of the connector 5, the contact elements 17 are arranged. In this section, the parting line between the housing parts 15, 16 extends coplanar to the plane which is spanned by the longitudinal axes of the two (with the exception of the crimped circular or annular cross-sections having) contact elements 17. Furthermore, each housing part 5, 16 comprises a cable-side portion, the Receiving a received in the housing portion of the cable is provided. In this section, the parting line runs parallel to the plane spanned by the longitudinal axes of the two contact elements 17 level. In the respective cable-side section, the two housing parts 15, 16 each form four projections 19 adjacent to the parting plane, wherein two projections 19 are arranged spaced apart on each side of both housing parts 15, 16 in the longitudinal direction of the connector 5. The two projections 19 each further define a boundary for a longitudinally extending recess 20 on each side of both housing parts 15, 16.
Zur Montage des Steckverbinders 1 werden die beiden Gehäuseteile 15, 16 in Längsrichtung derart zueinander versetzt positioniert, dass die Vorsprünge 19 des einen Gehäuseteils 15, 16 neben den Vorsprüngen 19 des anderen Gehäuseteils 15, 16 angeordnet sind. Dadurch können die Gehäuseteile 15, 16 bis zu einem Kontakt der die Trennebene ausbildenden Kontaktflächen beider Gehäuseteile 15, 16 (in einer Richtung senkrecht zur Längsrichtung) zusammengesteckt werden, ohne dass die Vorsprünge 19 kollidieren. Die Vorsprünge 9 beider Gehäuseteile 15, 16 befinden sich dann in den Vertiefungen 20 des jeweils anderen Gehäuseteils 15, 16. For mounting the connector 1, the two housing parts 15, 16 are positioned offset relative to one another in the longitudinal direction such that the projections 19 of one housing part 15, 16 are arranged next to the projections 19 of the other housing part 15, 16. As a result, the housing parts 15, 16 can be plugged together (in a direction perpendicular to the longitudinal direction) until the contact surfaces of the two housing parts 15, 16 forming the parting plane contact each other, without the projections 19 colliding. The projections 9 of the two housing parts 15, 16 are then located in the recesses 20 of the respective other housing part 15, 16th
Eine Verbindung der Gehäuseteile 15, 16 erfolgt anschließend durch ein Verschieben relativ zueinander in Längsrichtung, bis die in den Fig. 6 bis 8 dargestellte Endstellung erreicht ist. In dieser Endstellung überdecken die vier Vorsprünge 19 beider Gehäuseteile 15, 16 einander zumindest teilweise. Dadurch wird verhindert, dass sich die Gehäuseteile 15, 16 in einer Richtung quer zur Längsrichtung der Steckverbinder 5 voneinander lösen können. A connection of the housing parts 15, 16 is then carried out by moving relative to each other in the longitudinal direction until the end position shown in FIGS. 6 to 8 is reached. In this end position, the four projections 19 of both housing parts 15, 16 at least partially overlap one another. This prevents that the housing parts 15, 16 in a direction transverse to the longitudinal direction of the connector 5 can separate from each other.
Ein Lösen der Gehäuseteile 15, 16 voneinander in Längsrichtung wird durch eine Rastverbindung verhindert. Die Rastverbindung wird jeweils von Rastabschnitten 19a der kabelseitig gelegenen Vorsprünge 19 des ersten Gehäuseteils 6 im Zusammenwirken mit einem kabelseitigen Endabschnitt 21 des zweiten Gehäuseteils 16 ausgebildet. Die Rastabschnitte 19a verbreitern sich in Richtung des kabelseitigen Endes des ersten 6 Gehäuseteils, wodurch schräg zur Längsrichtung verlaufende Kontaktflächen ausgebildet werden. Auf diese Kontaktflächen wird der Endabschnitt 21 des zweiten Gehäuseteils 16 aufgeschoben, wobei die Innenbreite des Endabschnitts 21 kleiner als die aximalbreite zwischen den beiden Rastabschnitten 19a ist. Der Endabschnitt 21 des zweiten Gehäuseteils 16 wird daher beim Überfahren der Rastabschnitte 19a elastisch aufgeweitet und schnappt dadurch in der Endstellung hinter diese. A release of the housing parts 15, 16 from each other in the longitudinal direction is prevented by a latching connection. The latching connection is in each case formed by latching sections 19a of the cable-side projections 19 of the first housing part 6 in cooperation with a cable-side end section 21 of the second housing part 16. The latching portions 19 a widen in the direction of the cable-side end of the first 6 housing part, which obliquely to Longitudinally extending contact surfaces are formed. On these contact surfaces, the end portion 21 of the second housing part 16 is pushed, wherein the inner width of the end portion 21 is smaller than the aximalbreite between the two latching portions 19 a. The end portion 21 of the second housing part 16 is therefore expanded elastically when driving over the locking portions 19a and thereby snaps behind in the end position.
Beim Einschnappen hinter die Rastabschnitte 19a kann sich der Endabschnitt 21 des zweiten Gehäuseteils 16 nicht vollständig zurückverformen, sondern dieser liegt unter elastischer Aufweitung an Kontaktflächen eines Endabschnitts 22 des ersten Gehäuseteils 15 an. Im Bereich dieser Kontaktflächen weist der erste Gehäuseteil 15 dazu eine größere Breite als im Bereich der Vertiefungen 20 auf. When snapping behind the locking portions 19a, the end portion 21 of the second housing part 16 can not completely zurückverformen, but this is under elastic expansion of contact surfaces of an end portion 22 of the first housing part 15 at. In the area of these contact surfaces, the first housing part 15 has a greater width than in the region of the depressions 20.
Durch das Anliegen des Endabschnitts 21 des zweiten Gehäuseteils 16 unter elastischer Aufweitung und damit Vorspannung wird der Endabschnitt 22 und teilweise der sich daran anschließende Abschnitt des ersten Gehäuseteils 15 komprimiert, wodurch sich der innerhalb des ersten Gehäuseteils 15 ausgebildete Aufnahmeraum in diesen Abschnitten verkleinert. Dies führt zu einer klemmenden Fixierung eines in diesen Abschnitten vorgesehenen Kabelmantels des Kabels. Diese Fixierung dient zum einen als Zugentlastung für die Verbindung zwischen den Kontaktelementen 17 und den Adern des Kabels und soll zum anderen ein Verdrehen des Kabels in dem Gehäuse verhindern. Due to the abutment of the end portion 21 of the second housing part 16 under elastic expansion and thus bias the end portion 22 and partially of the adjoining portion of the first housing part 15 is compressed, whereby the formed within the first housing part 15 receiving space decreases in these sections. This leads to a clamping fixation of provided in these sections cable sheath of the cable. This fixation serves as a strain relief for the connection between the contact elements 17 and the wires of the cable and is intended to prevent the other a twisting of the cable in the housing.
Verbessert wird die Verbindung des Kabels in dem Gehäuse noch durch mehrere in der Wand des Aufnahmeraums (um die Längsrichtung des jeweiligen Steckverbinders 5) umlaufend angeordnete, in der Nähe des Endabschnitts 22 angeordneten Vorsprünge 23 des ersten Gehäuseteils 15. Diese dringen infolge der Deformation des ersten Gehäuseteils 15 in den Kabelmantel ein, wodurch eine formschlüssige Verbindung ausgebildet wird. The connection of the cable in the housing is further improved by a plurality of projections 23 of the first housing part 15 arranged circumferentially in the wall of the receiving space (around the longitudinal direction of the respective connector 5) and arranged in the vicinity of the end section 22. These penetrate as a result of the deformation of the first one Housing part 15 in the cable sheath, whereby a positive connection is formed.
Die Adern der Kabel sollen auch in den von den Kabelmänteln befreiten Abschnitten innerhalb der Gehäuse der Steckverbinder verdrillte Anordnungen aufweisen. Dabei soll die Verdrillung möglichst derjenigen entsprechen, die die Adern innerhalb der Kabelmäntel aufweisen. Durch die Festlegung der steckseitigen Enden der Leiter in den Kontaktelementen 17, die wiederum innerhalb der Gehäuse fixiert sind, sowie durch die Sicherung der Kabelmäntel gegen ein Verdrehen durch die klemmenden Fixierungen kann in ausreichendem Maße sichergestellt werden, dass sich die Verdrillungen in den von den Kabelmänteln befreiten Abschnitten der Kabel nicht auflösen. The wires of the cables should also have twisted arrangements within the housings of the connectors in the sections removed from the cable sheaths. The twist should as far as possible correspond to those that have the wires within the cable sheaths. By fixing the plug ends of the ladder in the contact elements 17, which in turn are fixed within the housing, as well as by securing the cable sheaths against rotation by the clamping fixings can be sufficiently ensured that the twists in the freed from the cable sheath sections of the cables do not dissolve.
Die beiden Gehäuseteile 15, 16 der Steckverbinders 5 sind vollständig aus elektrisch nicht leitfähigem Kunststoff ausgebildet, wobei die einfache geometrische Form ein Spritzgießen vorteilhaft ermöglicht. Bei einer Entformungsrichtung, die senkrecht zu den Trennebenen ausgerichtet ist, weisen lediglich die zweiten Gehäuseteile Hinterschnitte in Form von steckseitigen Durchgangsöffnungen 23 auf, die mit Hilfe eines Schiebers der Spritzgießform erzeugt werden können. Die Vorsprünge 19 stellen durch das Vorsehen von Entformungsvertiefungen 24 keine Hinterschnitte bei der Entformung dar. The two housing parts 15, 16 of the connector 5 are completely formed 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 parts on undercuts in the form of plug-through openings 23, which can be generated by means of a slide of the injection mold. The projections 19 do not constitute undercuts during demoulding due to the provision of demolding depressions 24.
In die Gehäuse integrierte Schirmungen für die Steckverbinder 5 sind nicht vorgesehen. Infolge der im Wesentlichen bis zu den Kontaktelementen 17 fortgesetzten Verdrillungen der Adern ist das Übertragungsverhalten der Steckverbinder (mit damit verbundenen Twisted-Pair-Kabeln) für viele Hochfrequenz-Anwendungen ausreichend gut. In the housing integrated shielding for the connector 5 are not provided. Due to the twisting of the wires substantially to the contact elements 17, the transmission behavior of the connectors (with associated twisted pair cables) is sufficiently good for many high frequency applications.
In der Fig. 5 ist der Leiterplattensteckverbinder 2 isoliert dargestellt. Das Gehäuse 9 des Leiterplattensteckverbinders 2 bildet auf einer Seite ein Steckinterface aus, das komplementär zu einem von dem Mehrfachsteckverbinder 1 ausgebildeten Steckinterface ist. Das Steckinterface des Leiterplattensteckverbinders 2 umfasst mehrere (konkret fünf) (Durchgangs-)Öffnungen 25, innerhalb derer jeweils zwei der Kontaktelemente 18 (ein Kontaktelementepaar) in paralleler Ausrichtung angeordnet sind. Diese kontaktieren im zusammengesteckten Zustand der Steckverbindung die Kontaktelemente 17 des Mehrfachsteckverbinders 1. Die Querschnitte der Öffnungen 25 des Gehäuses 9 sind länglich-oval und entsprechen den Querschnitten der steckseitigen Abschnitte 28 der Gehäuse der Steckverbinder 5. Ein die Öffnungen 25 umgebender (Steck-)Abschnitt der Außenseite des Gehäuses 9 weist eine Form auf, die komplementär zu der Innenseite eines Steckabschnitts des Mehrfachgehäuses 3 ist. Somit ragen im gesteckten Zustand der Steckverbindung die steckseitigen Abschnitte 28 der Steckverbinder 5 in die Öffnungen 25 des Gehäuses 9 des Leiterplattensteckverbinders 2 und der Steckabschnitt des Gehäuses 9 des Leiterplattensteckverbinders 2 in den Steckabschnitt des Mehrfachgehäuses 3. In Verbindung mit der Fixierung durch die Rastverbindung (Rastlasche 8 und Vorsprung 10) kann dadurch eine hohe mechanische Belastbarkeit der Steckverbindung erreicht werden. In Fig. 5, the PCB connector 2 is shown isolated. The housing 9 of the printed circuit board connector 2 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 25, within each of which two of the contact elements 18 (a pair of contact elements) are arranged in parallel alignment. These contact in the assembled state of the connector, the contact elements 17 of the multiple connector 1. The cross sections of the openings 25 of the housing 9 are elongated oval and correspond to the cross sections of the plug-side sections 28 of the housing of the connector 5. A the openings 25 surrounding (plug) section the outside of the housing 9 has a shape which is complementary to the inside of a plug-in portion of the multiple housing 3. Thus, in the mated state the plug connection, the plug-side sections 28 of the connector 5 in the openings 25 of the housing 9 of the printed circuit board connector 2 and the plug portion of the housing 9 of the printed circuit board connector 2 in the plug portion of the multiple housing 3. In conjunction with the fixation by the locking connection (latching tab 8 and projection 10) This allows a high mechanical strength of the connector can be achieved.
Die Kontaktelemente 17 weisen einen um 90° abgewinkelten Verlauf innerhalb des Gehäuses 9 auf. Die leiterplattenseitigen Enden der Kontaktelemente 17 überragen das Gehäuse 9 des Leiterplattensteckverbinders 2, so dass diese Kontaktstellen einer Leiterplatte (nicht dargestellt) kontaktieren können. Dabei können die Enden der Kontaktelemente in Öffnungen der Leiterplatte eingreifen, um den Leiterplattensteckverbinder 2 auch mechanisch mit der Leiterplatte zu verbinden. Zur weiteren mechanischen Stabilisierung dienen zapfenförmige Vorsprünge 28, die in entsprechende Öffnungen der Leiterplatte eingreifen können. The contact elements 17 have a 90 ° angled course within the housing 9. The printed circuit board-side ends of the contact elements 17 project beyond the housing 9 of the printed circuit board connector 2, so that these contact points of a printed circuit board (not shown) can contact. In this case, the ends of the contact elements can engage in openings of the printed circuit board in order to mechanically connect the printed circuit board connector 2 to the printed circuit board. For further mechanical stabilization serve peg-shaped projections 28 which can engage in corresponding openings of the circuit board.
Das Gehäuse 9 des Leiterplattensteckverbinders 2 ist ebenfalls vollständig aus elektrisch nicht leitfähigem Kunststoff ausgebildet, wobei die geometrisch einfache Form eine Herstellung durch Spritzgießen vereinfacht. The housing 9 of the printed circuit board connector 2 is also completely formed of electrically non-conductive plastic, wherein the geometrically simple shape simplifies manufacture by injection molding.
Die Fig. 1 1 bis 14 zeigen eine Steckverbindung mit einem Steckverbinder, der ebenfalls Teil des erfindungsgemäßen Systems ist, zu dem auch die Steckverbinder des Mehrfachsteckverbinders der Fig. 1 bis 8 gehören. Der Steckverbinder ist in diesem Fall als Einfachsteckverbinder ausgebildet und zur Verbindung mit einem entsprechenden (Einfach-)Gegensteckverbinder vorgesehen. Der Gegensteckverbinder ist wiederum als Leiterplattensteckverbinder 2 ausgebildet. 1 to 14 show a connector with a connector which is also part of the system according to the invention, which also includes the connector of the multiple connector of FIGS. 1 to 8. The connector is designed in this case as a single connector and provided for connection to a corresponding (single) mating connector. The mating connector is again designed as a printed circuit board connector 2.
Als Teil des erfindungsgemäßen Systems umfasst das Gehäuse des Steckverbinders 5 einen ersten Gehäuseteil 15, der identisch zu den ersten Gehäuseteilen 15 der Steckverbinder 5 des Mehrfachsteckverbinders 1 ist. Der zweite Gehäuseteil 16 ist dagegen für die Nutzung als Einfachsteckverbinder angepasst ausgebildet. Dazu umfasst der zweite Gehäuseteil 16 eine elastische auslenkbare Rastlasche 26 mit einer Öffnung, in die beim Zusammenstecken der Steckverbindung ein schräg ansteigend verlaufender Vorsprung 27 des Gehäuses 9 des Leiterplattensteckverbinders 2 eingreifen kann. Auf der die Innenseite des Gehäuses 9 ausbildenden Seite ist die Form des zweiten Gehäuseteils 16, insoweit diese mit dem ersten Gehäuseteil zusammenwirkt, identisch zu derjenigen der zweiten Gehäuseteile 16 der Steckverbinder 5 des Mehrfachsteckverbinders 1. As part of the system according to the invention, the housing of the connector 5 comprises a first housing part 15, which is identical to the first housing parts 15 of the connector 5 of the multiple connector 1. The second housing part 16, however, is designed adapted for use as a single connector. For this purpose, the second housing part 16 comprises an elastically deflectable latching tab 26 having an opening into which, when the plug-in connection is plugged together, an obliquely rising projection 27 of the housing 9 of the circuit board connector 2 can intervene. On the inside of the housing 9 forming side is the shape of the second housing part 16, insofar as this cooperates with the first housing part, identical to that of the second housing parts 16 of the connector 5 of the multiple connector. 1
