Description

Die Erfindung betrifft einen elektrisches Kupplungselement, zur Anordnung in einem Steckverbindergehäuse, vorzugsweise in einem modularen Steckverbindergehäuse, bestehend aus einem elektrisch isolierenden Grundkörper, wobei der Grundkörper Kontaktkammern mit darin angeordneten elektrischen Kontaktelementen aufweist, wobei die Kontaktelemente vorzugsweise als Buchsen- oder Stiftkontakte ausgebildet sind, wobei die Kontaktelemente eine in Steckrichtung vordere Kontaktseite und eine in Steckrichtung hintere Kabelanschlussseite aufweisen, wobei die Kabelanschlussseite über ein Anschlussmittel zur Befestigung eines elektrischen Leiters an der Kabelanschlussseite des Kontaktelementes verfügt, und wobei der Grundkörper Öffnungen aufweist, welche einen Zugriff auf die Anschlussmittel ermöglichen.The invention relates to an electrical coupling element, for arrangement in a connector housing, preferably in a modular connector housing, consisting of an electrically insulating body, wherein the body contact chambers having disposed therein electrical contact elements, wherein the contact elements are preferably formed as a socket or pin contacts, said the contact elements have a front contact side in the plug-in direction and a cable terminal side rear in the plug-in direction, wherein the cable connection side has a connection means for fastening an electrical conductor to the cable connection side of the contact element, and wherein the base body has openings which allow access to the connection means.

Ein derartiges elektrisches Kupplungselement wird benötigt, um elektrisch leitende Litzen, Adern und Kabel reversibel miteinander zu verbinden. Ein Vorteil der Anordnung in einem modularen Steckverbindergehäuse ist, dass eine große Flexibilität in der Zusammenstellung der einzelnen Kupplungselemente eines Steckverbinders besteht. Dadurch kann ein Steckverbinder verschiedene Leiterquerschnitte, sowie verschiedene Arten von Signalleitern aufnehmen. So können beispielsweise elektrische Leiter mit optischen Leitern und pneumatischen Leitern in einem Steckverbinder nach Wunsch kombiniert werden.Such an electrical coupling element is needed to reversibly connect electrically conductive strands, wires and cables together. An advantage of the arrangement in a modular connector housing is that there is great flexibility in assembling the individual coupling elements of a connector. This allows a connector to accommodate different conductor cross sections, as well as different types of signal conductors. For example, electrical conductors with optical conductors and pneumatic conductors in a connector can be combined as desired.

Stand der TechnikState of the art

Derartige Steckverbinder mit modularem Aufbau sind bereits vielfach aus dem Stand der Technik bekannt. Beispielhaft seien hier die DE 34 42 056 A1 , die DE 298 12 500 U1 , die DE 197 07 120 C1 oder auch die DE 43 11 781 C1 bekannt. Alle bereits bekannten Steckverbinder verfügen über einen Aufnahmerahmen, der zur Aufnahme einzelner Kupplungselemente, sogenannten Module, verschiedener Art vorgesehen sind.Such connectors of modular construction are already widely known in the art. Exemplary here are the DE 34 42 056 A1 , the DE 298 12 500 U1 , the DE 197 07 120 C1 or even the DE 43 11 781 C1 known. All already known connectors have a receiving frame, which are provided for receiving individual coupling elements, so-called modules of various types.

Die einzelnen elektrischen Kupplungselemente sind meist von kleiner Bauform und verfügen über eine Mehrzahl von elektrischen Leitern. Durch eine kompakte, einheitliche Baugröße der Kupplungselemente können diese in beliebiger Reihenfolge in einem Steckverbindergehäuse angeordnet werden.The individual electrical coupling elements are usually of small design and have a plurality of electrical conductors. By a compact, uniform size of the coupling elements they can be arranged in any order in a connector housing.

Nachteilig wirkt sich bei allen aus dem Stand der Technik bekannten Steckverbindern aus, dass auf Grund der kompakten, einheitlichen Baugröße der Kupplungselemente die Arten der darin angeordneten elektrischen Kontaktelemente stark eingeschränkt ist.A disadvantage of all known from the prior art connectors that due to the compact, uniform size of the coupling elements, the types of electrical contact elements arranged therein is severely limited.

So verfügen die meisten elektrischen Kupplungselemente über Kontaktelemente, die an die anzuschließenden Leiter gekrimpt sind. Diese werden in Steckrichtung in das Kupplungselement eingeführt wo sie verrasten und nur mit einem Spezialwerkzeug entfernt werden können. Alternativ sind aus dem Stand der Technik Kontaktelemente mit so genannten Axialschraubanschlüssen bekannt.Most electrical coupling elements have contact elements which are crimped to the conductors to be connected. These are introduced in the insertion direction in the coupling element where they lock and can only be removed with a special tool. Alternatively, contact elements with so-called axial screw connections are known from the prior art.

Eine Verwendung von Kontaktelementen mit Schraubanschluss, für welchen lediglich ein Standardschraubendreher statt spezielles Werkzeug zur Montage und Demontage erforderlich ist, ist nicht möglich. Da die Verschraubung des Kontaktelements meist über Öffnungen an der Seite des Kupplungselements erfolgt, sind durch offen liegende Verschraubungen und die kompakte Bauform der Kupplungselemente die Luft- und Kriechstrecken zwischen der Verschraubung und dem nächstliegenden Kupplungselement oder dem Aufnahmerahmen zu gering.It is not possible to use contact elements with a screw connection, for which only a standard screwdriver is required instead of special tools for assembly and disassembly. Since the screwing of the contact element usually takes place via openings on the side of the coupling element, the air and creepage distances between the screw and the nearest coupling element or the receiving frame are too low due to open fittings and the compact design of the coupling elements.

Durch zu geringe Luft- und Kriechstrecken kann es zur Verfälschung von Signalen oder sogar zu Kurzschlüssen zwischen verschiedenen Kontaktelementen oder zwischen Kontaktelementen und dem Aufnahmerahmen führen.Insufficient air and creepage distances can lead to falsification of signals or even to short circuits between different contact elements or between contact elements and the receiving frame.

Ein weiteres Problem bei offenliegenden Verschraubungen an Kupplungselementen ist die Berührsicherheit, welche nicht gegeben ist. Leicht kann von Personen bei der Handhabung von gesteckten, unter Last stehenden Kupplungselementen die freiliegenden Verschraubungen berührt werden.Another problem with exposed screw on coupling elements is the touch safety, which is not given. Easy can of Persons handling exposed mating coupling elements are exposed to the exposed glands.

Aus der US2006/141871 A1 ist ein Kupplungselement mit den Merkmalen des Oberbegriffs von Anspruch 1 bekannt.From the US2006 / 141871 A1 a coupling element with the features of the preamble of claim 1 is known.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kupplungselement so auszubilden, dass es mit Schraubkontakten genutzt werden kann, ohne dass ansonsten spezielles Werkzeug zur Montage erforderlich ist und gleichzeitig das Risiko von Kurzschlüssen verringert wird.The invention is therefore based on the object, a coupling element in such a way that it can be used with screw, without otherwise special tool for mounting is required and at the same time the risk of short circuits is reduced.

Diese Aufgabe wird durch ein Kupplungselement nach Anspruch 1 gelöst.This object is achieved by a coupling element according to claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Bei der Erfindung handelt es sich um ein elektrisches Kupplungselement, das dafür vorgesehen ist, alleine oder mit einer Mehrzahl anderer Kupplungselemente in einem Steckverbindergehäuse angeordnet zu werden. Zur Aufnahme in dem Steckverbindergehäuse ist ein Aufnahmerahmen im Steckverbindergehäuse vorgesehen, welcher die Kupplungselemente hält und mittels welchem die Kupplungselemente am Steckverbindergehäuse fixierbar sind. Der rechteckige Grundkörper des Kupplungselement bestehen aus einem elektrisch isolierenden Material und weist ein oder mehrere, längs der Steckrichtung durchgehende Aufnahmekammern für elektrische Kontaktelemente auf. Die als Stift- oder Buchsenkontakte ausgebildeten Kontaktelemente sind so im Kupplungselement angeordnet, dass sich ihre zur elektrischen Kontaktierung vorgesehener Kontaktseite im in Steckrichtung vorderen Steckbereich des Kupplungselements befindet.In the invention is an electrical coupling element which is intended to be arranged alone or with a plurality of other coupling elements in a connector housing. For receiving in the connector housing, a receiving frame is provided in the connector housing, which holds the coupling elements and by means of which the coupling elements can be fixed to the connector housing. The rectangular base body of the coupling element consist of an electrically insulating material and has one or more, along the direction of insertion continuous receiving chambers for electrical contact elements. The trained as pin or socket contacts contact elements are arranged in the coupling element, that is provided for electrical contacting contact side in the plug-in direction front plug-in area of the coupling element.

Das Kupplungselement verfügt über einen, dem Steckbereich abgewandten, in Steckrichtung hinten liegenden Anschlussbereich. Im Anschlussbereich ist der hintere Teil der elektrischen Kontaktelemente, die Kabelanschlussseite aufgenommen. Anzuschließende elektrische Leiter werden in den Anschlussbereich in das Kupplungselement eingeführt und in der Kabelanschlussseite des elektrischen Kontaktelementes mechanisch befestigt.The coupling element has a connecting region which faces away from the plug-in region and is located behind in the plugging direction. In the connection area is the rear part of the electrical contact elements, the cable connection side added. To be connected electrical conductors are inserted into the connection area in the coupling element and mechanically fastened in the cable connection side of the electrical contact element.

Das Kupplungselement weist zweckmäßig Rastmittel zur Fixierung des Kupplungselementes im Aufnahmerahmen des Steckverbindergehäuses auf. Die Rastmittel befinden sich an den zwei schmalen Längsseiten des rechteckigen Kupplungselements. Dadurch liegen mehrere aneinandergereihte, in dem Aufnahmerahmen angeordnete Kupplungselemente mit ihren breiten Längsseiten aneinander.The coupling element expediently has latching means for fixing the coupling element in the receiving frame of the plug connector housing. The locking means are located on the two narrow longitudinal sides of the rectangular coupling element. As a result, a plurality of juxtaposed, arranged in the receiving frame coupling elements are with their wide longitudinal sides together.

An einer der beiden breiten Längsseiten verfügt das Kupplungselement über eine Anzahl an Öffnungen, die der Anzahl an Aufnahmekammern im Grundkörper identisch ist. Die Öffnungen reichen von der Außenseite des Kupplungselements bis in die jeweilige Aufnahmekammer, welcher die Öffnungen zugeordnet sind.On one of the two wide longitudinal sides, the coupling element has a number of openings, which is identical to the number of receiving chambers in the main body. The openings extend from the outside of the coupling element to the respective receiving chamber, which are associated with the openings.

Die Öffnungen sind zur Aufnahme von Anschlussmitteln vorgesehen, mittels welcher die anzuschließenden elektrischen Leiter am Kontaktelement befestigt werden. Das Anschlussmittel ist vorzugsweise als Schraube ausgebildet, welche in die Kabelanschlussseite des Kontaktelementes eingeschraubt wird und so den elektrischen Leiter fixiert.The openings are provided for receiving connection means, by means of which the electrical conductors to be connected are fastened to the contact element. The connection means is preferably designed as a screw, which is screwed into the cable connection side of the contact element and thus fixes the electrical conductor.

Ebenfalls an der breiten Längsseite, welche auch die Öffnungen für die Anschlussmittel aufweist, ist erfindungsgemäß eine Abdeckblende vorgesehen. Die Abdeckblende ist ein elektrisch nicht leitfähiges, flächig ausgebildetes Element, welches eine der breiteren Längsseiten des Kupplungselements teilweise verdeckt.Also on the wide longitudinal side, which also has the openings for the connection means, a Abdeckblende is provided according to the invention. The Abdeckblende is an electrically non-conductive, areal trained element which partially covers one of the wider longitudinal sides of the coupling element.

Die Abdeckblende ist zweckmäßig beweglich angebracht, wobei sie eine lineare Bewegung, in und entgegen der Steckrichtung ausführen kann. Eine in Steckrichtung vordere Endposition der Abdeckblende bildet eine geöffnete Stellung, und eine in Steckrichtung hintere Endposition eine geschlossene Stellung. Die Abdeckblende verfügt über eine Anzahl an Durchbrüchen, die der Anzahl von Öffnungen im Grundkörper identisch ist.The cover is expedient movably mounted, where they can perform a linear movement, in and against the direction of insertion. An end position in front of the cover panel in the direction of insertion forms an open one Position, and a plug-in direction rear end position a closed position. The cover has a number of openings, which is identical to the number of openings in the body.

Die Durchbrüche entsprechen in ihrem Durchmesser den Öffnungen im Grundkörper und haben bei geöffneter Stellung der Abdeckblende eine deckungsgleiche Position mit den Öffnungen im Grundkörper. Wird die Abdeckblende in die geschlossene Stellung verschoben, verdeckt die Abdeckblende die Öffnungen im Grundkörper und der Zugriff auf die in den Öffnungen angeordneten Anschlussmittel ist nicht möglich.The openings correspond in diameter to the openings in the base body and have in the open position of the cover a congruent position with the openings in the body. If the cover is moved to the closed position, the Abdeckblende covers the openings in the body and access to the arranged in the openings connecting means is not possible.

Die Abdeckblende ist in Steckrichtung so ausgebildet, dass sie im vollständig gesteckten Zustand des Kupplungselementes mit einem Gegenkupplungselement mit der Abdeckblende des Gegenkupplungselements frontal in Steckrichtung in Kontakt gelangt. In diesem vollständig gesteckten Zustand befinden sich beide Abdeckblenden, die des Kupplungselements und die des Gegenkupplungselements, in geschlossener Stellung, dass ein Zugriff auf die Anschlussmittel nicht möglich ist.The filler panel is formed in the insertion direction so that it comes in the fully inserted state of the coupling element with a counter-coupling element with the cover of the counter-coupling element frontally in the insertion direction in contact. In this fully inserted state, both cover panels, which are the coupling element and that of the counter-coupling element, in the closed position, that access to the connection means is not possible.

Diese hier als Buchsenkontakte ausgebildeten Kontaktelemente 20 dienen zur Kontaktierung mit den Kontaktelementen 20' eines Gegenkupplungselements 1'.The front in the insertion direction S region of the contact elements 20 is formed by the contact side. These contact elements 20 designed here as socket contacts serve for contacting with the contact elements 20 'of a counter-coupling element 1'.

Im mittleren Bereich der Fig. 3 ist der Grundkörper 10 des Kupplungselements 1 dargestellt. Der Steckbereich 12 des Kupplungselements 1 ist zur Aufnahme der Kontaktseite 22 der Kontaktelemente 20 vorgesehen und der Anschlussbereich 14 zur Aufnahme der Kabelanschlussseite 24 der Kontaktelemente 20.In the middle area of the Fig. 3 the main body 10 of the coupling element 1 is shown. The plug-in region 12 of the coupling element 1 is provided for receiving the contact side 22 of the contact elements 20 and the connection region 14 for receiving the cable connection side 24 of the contact elements 20.

An der oberen, breiten Längsseite des Grundkörpers 10 sind in entsprechender Anzahl der Kontaktelemente 20 - hier fünf - Öffnungen 18 vorgesehen. Die Öffnungen 18 reichen von der Oberseite des Grundkörpers 10 bis in die Kontaktkammern 11, in welchen die Kontaktelemente 20 angeordnet sind. Die Öffnungen 18 sind dafür vorgesehen, die Anschlussmittel 28 aufzunehmen und den Zugriff auf diese zu ermöglichen. Die Anschlussmittel 28 werden durch die Öffnungen 18 in die Kabelanschlussseiten 24 der Kontaktelemente 20 eingeschraubt.On the upper, wide longitudinal side of the base body 10 are provided in a corresponding number of the contact elements 20 - here five - 18 openings. The openings 18 extend from the top of the main body 10 into the contact chambers 11, in which the contact elements 20 are arranged. The openings 18 are intended to receive the connection means 28 and to allow access to them. The connection means 28 are screwed through the openings 18 in the cable connection sides 24 of the contact elements 20.

Der Grundkörper 10 weist an seinen schmalen Längsseiten vorzugsweise Führungsnuten 17 auf, welche zur Führung und Verankerung der Abdeckblende 30 dienen. Die Abdeckblende 30 wird mittels Führungsstegen 37 in den Führungsnuten 17 geführt und kann so eine lineare Bewegung in Steckrichtung S zwischen der Montageposition A und der Arbeitsposition B ausführen.The main body 10 has on its narrow longitudinal sides preferably guide grooves 17, which serve for guiding and anchoring the cover panel 30. The cover panel 30 is guided by means of guide webs 37 in the guide grooves 17 and can thus perform a linear movement in the insertion direction S between the mounting position A and the working position B.

In Steckrichtung S neben den Öffnungen 18 befinden sich zusätzliche Vertiefungen 19, welche zur Verrastung der Abdeckblende 30 in der Montageposition A dienen. Dafür rasten Rastmittel 38, die sich an der dem Grundkörper 10 zugewandten Seite der Abdeckblende 30 befinden in die Vertiefungen 19 ein. Die Vertiefungen 19 entsprechen in ihrer Form den Öffnungen 18, wodurch die Abdeckblende 30 in der Arbeitsposition B mit den Rastmitteln 39 in den Öffnungen 18 verrasten kann.In the insertion direction S next to the openings 18 are additional recesses 19, which serve to lock the cover 30 in the mounting position A. For latching detent means 38, which are located on the base body 10 facing side of the cover 30 are in the recesses 19 a. The recesses 19 correspond in shape to the openings 18, whereby the cover panel 30 can latch in the working position B with the locking means 39 in the openings 18.

Die Rastmittel 38 sind als flache Erhebungen an der Abdeckblende 30 ausgeführt. Diese passen von Form und Größe genau in die Öffnungen 18 und die Vertiefungen 19 und halten so die Abdeckblende 30 in Montageposition A bzw. in Arbeitsposition B.The locking means 38 are designed as flat elevations on the Abdeckblende 30. These fit of shape and size exactly in the openings 18 and the recesses 19, thus keeping the cover panel 30 in mounting position A and in working position B.

Im rechten Bereich der Fig. 3 ist eine erfindungsmäßige Abdeckblende 30 dargestellt, welche auch in Fig. 4 von der dem Grundkörper 10 zugewandten Seite gezeigt ist. Die Abdeckblende 30 ist grob u-förmig ausgebildet und aus elektrisch nicht leitfähigem Material. Die U-Form dient dazu, dass die Abdeckblende 30 den Grundkörper 10 zumindest teilweise umfasst. Die an der Innenseite der Abdeckblende 30 angeformten Führungsstege 37 greifen in die Führungsnuten 17 am Grundkörper 10 ein und halten so die Abdeckblende 30 am Grundkörper 10. Die Führungsnuten 17 lassen eine lineare, in Steckrichtung S gerichtete Bewegung der Abdeckblende 30 von der Montagposition A zur Arbeitsposition B zu.In the right area of the Fig. 3 an inventive Abdeckblende 30 is shown, which also in Fig. 4 from the base body 10 facing side is shown. The cover panel 30 is roughly U-shaped and made of electrically non-conductive material. The U-shape serves to ensure that the cover panel 30 at least partially surrounds the base body 10. The integrally formed on the inside of the cover panel 30 guide webs 37 engage in the guide grooves 17 on the base body 10 and thus hold the Abdeckblende 30 on the base body 10. The guide grooves 17 leave a linear, in Plug direction S directed movement of the Abdeckblende 30 from the mounting position A to the working position B.

In der dargestellten Ausführungsform verfügt die Abdeckblende 30 über ein Federelement 34, welches im Steckrichtung S vorderen Bereich 32 an der Abdeckblende 30 angebracht ist. Das Federelement 34 übt eine Kraft auf die Abdeckblende 30 aus, wenn das Kupplungselement 1 mit einem zweiten Kupplungselement 1' kontaktiert ist und zwingt die Abdeckblende 30 in die Arbeitsposition B.In the illustrated embodiment, the cover panel 30 has a spring element 34 which is mounted in the insertion direction S front portion 32 on the cover panel 30. The spring element 34 exerts a force on the cover panel 30 when the coupling element 1 is contacted with a second coupling element 1 'and forces the cover panel 30 in the working position B.

Erfindungsgemäß sind an der dem Grundkörper 10 zugewandten Seite der Abdeckblende 30 Rippen 36 angeformt. Die Rippen 36 tauchen in Nuten 16 am Grundkörper 10 ein. Durch das Eintauchen der Rippen 36 in die Nuten 16 werden die elektrischen Kriechstrecken zwischen den einzelnen Kontaktelementen 20 im Grundkörper 10 vergrößert.In accordance with the invention, ribs 36 are integrally formed on the side of the cover panel 30 facing the main body 10. The ribs 36 dive into grooves 16 on the base body 10. By immersing the ribs 36 in the grooves 16, the electrical creepage distances between the individual contact elements 20 in the base body 10 are increased.

In der gezeigten Ausführungsform verfügt die Abdeckblende 30 über einen zusätzlichen Anschlag 39, welcher beim Verschieben der Abdeckblende 30 in die Montageposition A ein versehentliches Entfernen der Abdeckblende 30 vom Grundkörper 10 verhindern soll.In the illustrated embodiment, the cover panel 30 has an additional stopper 39, which is intended to prevent accidental removal of the cover panel 30 from the base body 10 when moving the cover panel 30 in the mounting position A.

Die Fig. 5 und die Fig. 6 zeigen jeweils ein Paar Kupplungselemente 1, 1' in nicht gestecktem Zustand bzw. in gestecktem Zustand. Zu erkennen sind die gegenüber dargestellten Kupplungselemente 1,1', wobei das Kupplungselement 1 mit Buchsenkontakten versehen ist, und das Kupplungselement 1' mit Stiftkontakten. Im jeweils in Steckrichtung S, S' hinteren Anschlussbereich 14, 14' der Grundkörper 10, 10' sind elektrische Leiter 3, 3' dargestellt, welche in den Kupplungselementen 1, 1' mit die hier nicht sichtbaren Kontaktelementen 20, 20' elektrisch verbunden sind. In Fig. 6 sind in gestecktem Zustand die Steckbereiche 12, 12' ineinander gesteckt.The Fig. 5 and the Fig. 6 each show a pair of coupling elements 1, 1 'in not plugged state or in the inserted state. Evident are the opposite illustrated coupling elements 1,1 ', wherein the coupling element 1 is provided with female contacts, and the coupling element 1' with pin contacts. In each case in the insertion direction S, S 'rear connection portion 14, 14' of the base body 10, 10 'electrical conductors 3, 3' are shown, which are in the coupling elements 1, 1 'with the non-visible contact elements 20, 20' electrically connected , In Fig. 6 are in plugged state, the plug-in areas 12, 12 'inserted into one another.

Erfindungsgemäß sind in Fig. 5 die Abdeckblenden 30, 30' in der Montageposition A dargestellt. In dieser Position ermöglichen sie einen Zugriff auf die Anschlussmittel 28, 28' mit welchen die elektrischen Leiter 3, 3' in den Kontaktelementen 20, 20' mechanisch und elektrisch befestigt sind.According to the invention are in Fig. 5 the cover panels 30, 30 'shown in the mounting position A. In this position they provide access to the Connection means 28, 28 'with which the electrical conductors 3, 3' in the contact elements 20, 20 'are mechanically and electrically fixed.

Im gesteckten Zustand, wie er in Fig. 6 dargestellt ist, sind die Abdeckblenden 30, 30'in Arbeitsposition B und verdecken so den Zugriff auf die Anschlussmittel 28, 28'. Durch das Stecken der Kupplungselemente 1, 1' ineinander haben sich die Abdeckblenden 30, 30' gegenseitig in die Arbeitsposition B verschoben. Die Federelemente 34, 34' drücken gegeneinander und üben so eine Kraft auf die Abdeckblenden 30, 30' aus, welche die Abdeckblenden 30, 30' in Arbeitsposition B halten.In mated condition, as in Fig. 6 is shown, the cover panels 30, 30 'in working position B and thus cover the access to the connection means 28, 28'. By plugging the coupling elements 1, 1 'into one another, the cover panels 30, 30' mutually shifted to the working position B. The spring elements 34, 34 'press against each other and thus exert a force on the cover panels 30, 30', which hold the cover panels 30, 30 'in working position B.
