Description

Die Erfindung betrifft einen Verbindungsstecker zur elektrischen Verbindung eines ersten Anschlußsteckers eines ersten elektrischen Geräts, insbesondere einer ersten Sensor-Aktor-Box, mit einem zweiten Anschlußstecker eines zweiten elektrischen Geräts, insbesondere einer zweiten Sensor-Aktor-Box, mit einem Gehäuse und mit zwei in dem Gehäuse parallel zueinander angeordneten Gegensteckverbindern, wobei der erste Gegensteckverbinder mit dem ersten Anschlußstecker und der zweite Gegensteckverbinder mit dem zweiten Anschlußstecker verbindbar ist, wobei die beiden Gegensteckverbinder jeweils einen Kontaktträger mit mehreren Kontaktelementen aufweisen, die mit den Kontaktelementen der Anschlußstecker verbindbar sind, wobei die Kontaktelemente der beiden Gegensteckverbinder elektrisch miteinander verbunden sind, und wobei ein Verriegelungselement beweglich im Gehäuse angeordnet ist, mit dem der Verbindungsstecker an mindestens einem Gerät befestigbar ist.The invention relates to a connector for electrically connecting a first connector of a first electrical device, in particular a first sensor-actuator box, with a second connector of a second electrical device, in particular a second sensor-actuator box, with a housing and with two in the housing parallel spaced mating connectors, wherein the first mating connector with the first connector and the second mating connector with the second connector is connectable, wherein the two mating connectors each having a contact carrier with a plurality of contact elements, which are connectable to the contact elements of the connector, wherein the contact elements the two mating connectors are electrically connected to each other, and wherein a locking element is movably arranged in the housing, with which the connector is fastened to at least one device.

In der Praxis kommt es häufig vor, daß zwei oder mehrere elektrische Gerät elektrisch miteinander verbunden werden müssen. Bei derartigen elektrischen Geräten kann es sich beispielsweise um Verteilerboxen, insbesondere sogenannte Sensor-Aktor-Boxen handeln, mit deren Hilfe mehrere Sensoren oder Aktoren an einen gemeinsamen Bus angeschlossen werden können. Derartige Sensor-Aktor-Boxen weisen an ihrer Oberseite mehrere Anschlußstecker auf, die zum Anschluß eines mit einem Sensor oder Aktor verbundenen elektrischen Kabels dienen, wobei das Kabel dann einen zu dem Anschlußstecker korrespondierenden Gegenstecker aufweist. Die Anschlußstecker weisen dabei jeweils einen Kontaktträger mit mehreren Kontaktelementen auf, bei denen es sich entweder um Kontaktstifte oder um die korrespondierenden Buchsen handelt. In Abhängigkeit davon, ob in dem Kontaktträger die Kontaktstifte oder die Buchsen angeordnet sind, wird der Anschlußstecker als Stecker oder als Buchse bezeichnet.In practice, it often happens that two or more electrical equipment must be electrically connected to each other. Such electrical devices can be, for example, distribution boxes, in particular so-called sensor-actuator boxes, with the aid of which several sensors or actuators can be connected to a common bus. Such sensor-actuator boxes have on their upper side a plurality of connecting plugs, which serve to connect an electrical cable connected to a sensor or actuator, wherein the cable then has a mating connector corresponding to the connector. The connectors each have a contact carrier with a plurality of contact elements, which are either contact pins or the corresponding sockets. Depending on whether the contact pins or the sockets are arranged in the contact carrier, the connector is referred to as a plug or a socket.

Derartige Sensor-Aktor-Boxen, die auch als Sensor-Aktor-Verteiler bezeichnet werden, sind beispielsweise in dem Prospekt "AUTOMATIONWORX 2005", Seiten 254 - 257 der Phoenix Contact GmbH & CO. KG, Blomberg, dargestellt und aus der DE 295 05 272 U1 bekannt. Sie weisen in der Regel 4, 8 oder 16 Kontakteinsätze auf, die ein genormtes Innen- oder Außengewinde, beispielsweise M8, N10 oder M12, aufweisen. Derartige Sensor-Aktor-Verteiler werden üblicherweise in der Maschinen- und Anlagetechnik eingesetzt. Die Aufgabe eines Sensor-Aktor-Verteilers besteht in der Sammlung von Sensorsignalen bzw. in der Verteilung von Aktorsignalen. Die Sensor-Aktor-Verteiler dienen dabei als mechanische und/oder elektrische Schnittstellen in Bussystemen, über die eine Vielzahl von Sensoren und Aktoren an eine zentrale Steuer- oder Rechnereinheit angeschlossen werden. Die Verbindung einzelner Sensor-Aktor-Verteiler untereinander sowie der Sensor-Aktor-Verteiler mit der meist in einem Schaltschrank angeordneten Steuereinheit erfolgt bei sogenannten passiven Sensor-Aktor-Verteilern mit hochpoligen Stammkabeln. Bei sogenannten aktiven Sensor-Aktor-Verteilern werden die in den Sensor-Aktor-Verteilern gesammelten und ggf. vorverarbeiteten Signale seriell auf Busleitungen übertragen.Such sensor-actuator boxes, which are also referred to as sensor-actuator distributor are, for example, in the brochure "AUTOMATIONWORX 2005", pages 254-257 of Phoenix Contact GmbH & CO. KG, Blomberg, represented and from the DE 295 05 272 U1 known. They usually have 4, 8 or 16 contact inserts which have a standardized internal or external thread, for example M8, N10 or M12. Such sensor-actuator distributor are commonly used in machinery and equipment. The task of a sensor-actuator distributor consists in the collection of sensor signals or in the distribution of actuator signals. The sensor-actuator distributors serve as mechanical and / or electrical interfaces in bus systems, via which a plurality of sensors and actuators are connected to a central control or computer unit. The connection of individual sensor-actuator distributor with each other and the sensor-actuator distributor with the most commonly arranged in a control box control unit takes place in so-called passive sensor-actuator distributors with multi-pole trunk cables. In so-called active sensor-actuator distributors, the signals collected in the sensor / actuator distributors and possibly preprocessed are transmitted serially to bus lines.

Passive Sensor-Aktor-Verteiler werden meist mit fest angespritzten Stammleitungen angeboten. Darüber hinaus sind jedoch auch passive Sensor-Aktor-Verteiler bekannt, bei denen die Stammleitungen über Steckverbinder oder mit Hilfe von Federkraftklemmen an den Verteiler angeschlossen werden können. Entsprechend gibt es auch bei aktiven Sensor-Aktor-Verteilern verschiedene Möglichkeiten das Buskabel anzuschließen, wobei hier, ähnlich wie beim Anschluß einzelner Sensoren oder Aktoren, auch standardisierte Steckverbinder benutzt werden können.Passive sensor-actuator distributors are usually offered with permanently molded trunk lines. In addition, however, passive sensor-actuator distributor are known in which the trunk lines can be connected via connectors or by means of spring-loaded terminals to the distributor. Accordingly, there are various ways to connect the bus cable even with active sensor-actuator distributors, and here, similar to the connection of individual sensors or actuators, standardized connectors can be used.

Die Verbindung zweier Anschlußstecker zweier Sensor-Aktor-Boxen mit Hilfe elektrischer Kabel, die an ihren Enden passende Stecker oder Buchsen aufweisen, hat den Vorteil, daß die Kabel, aufgrund der an den Steckverbindern ausgebildeten Überwurfhülsen, welche ein Innen- oder Außengewinde aufweisen, mit den ein entsprechendes Außen- oder Innengewinde aufweisenden Anschlußsteckern mechanisch fest verbunden werden können. Nachteilig ist hierbei jedoch, daß insbesondere bei unmittelbar benachbart zueinander angeordneten Sensor-Aktor-Boxen die Verwendung mehrerer elektrischer Kabel leicht zu einem unübersichtlichen Aufbau führen kann, wobei darüber hinaus einzelne in den Sensor-Aktor-Boxen angeordnete Kontakteinsätze durch ankommende oder abgehende Kabel verdeckt werden können.The connection of two connectors of two sensor-actuator boxes using electrical cables having at their ends matching plugs or sockets, has the advantage that the cable, due to the formed on the connectors cap sleeves, which have an internal or external thread, with the corresponding external or internal thread having connector plugs can be mechanically firmly connected. The disadvantage here, however, that especially in immediately adjacent to each other arranged sensor actuator boxes, the use of multiple electrical cables can easily lead to a confusing structure, moreover, individual arranged in the sensor actuator boxes contact inserts are covered by incoming or outgoing cable can.

Darüber hinaus kann die Verbindung zwischen benachbarten oder mit geringem Abstand voneinander angeordneten Sensor-Aktor-Boxen auch mittels Verbindungssteckern erfolgen, welche häufig auch als Brückenglieder oder Verbindungsbrücken bezeichnet werden. Derartige Verbindungsstecker zur elektrischen Verbindung zweier benachbarter Sensor-Aktor-Boxen sind beispielsweise aus der DE 100 11 354 C1 bekannt. Der bekannte Verbindungsstecker weist zwei Kontaktträger auf, in denen jeweils achtundzwanzig Steckerstifte angeordnet sind. Die beiden Kontaktträger des bekannten Verbindungssteckers werden zusammen auf die in den beiden Sensor-Aktor-Boxen angeordneten korrespondierenden Kontaktträger, die jeweils korrespondierende Steckerbuchsen aufweisen, aufgesteckt. Die Verwendung eines solchen Verbindungssteckers führt zwar zu einem übersichtlicheren Aufbau, hier besteht jedoch der Nachteil, daß eine mechanische Befestigung des Verbindungssteckers auf den Sensor-Aktor-Boxen nicht oder nur schwer möglich ist.In addition, the connection between adjacent or closely spaced sensor-actuator boxes can also be done by means of connectors, which are often referred to as bridge members or connecting bridges. Such connector for the electrical connection of two adjacent sensor-actuator boxes are for example from the DE 100 11 354 C1 known. The known connector has two contact carrier, in each of which twenty-eight connector pins are arranged. The two contact carriers of the known connector plug are placed together on the arranged in the two sensor actuator boxes corresponding contact carrier, each having corresponding sockets. Although the use of such a connector leads to a clearer structure, but here there is the disadvantage that a mechanical attachment of the connector on the sensor-actuator boxes is not or only with difficulty.

Ein ähnlicher Verbindungsstecker ist auch aus der DE 297 03 367 U1 bekannt. Diese Druckschrift offenbart ein elektrisches Gerät bestehend aus mindestens zwei aneinanderreihbaren Modulen, wobei die einzelnen Module auf ihrer Oberseite Anschlussmittel zum Anschluss von Sensoren oder Aktoren aufweisen. Darüber hinaus weisen die einzelnen Module an ihren jeweiligen Längsseiten Kontaktmittel auf, so dass zwei benachbarte Module mit Hilfe eines Verbindungssteckers miteinander verbunden werden können. Der Verbindungsstecker weist ein im Wesentlichen U-förmiges Gehäuse mit zwei Schenkeln auf, deren Enden in die Ausnehmungen in den Modulen eingesteckt werden können, in denen die Kontaktmittel angeordnet sind. Hierzu sind in den Schenkeln des Verbindungssteckers korrespondierende Kontaktmittel ausgebildet. Zur mechanischen Befestigung des Verbindungssteckers mit den beiden Modulen sind an den jeweils gegenüberliegenden Enden der Schenkel des Verbindungssteckers Bohrungen vorgesehen, in denen Gewindeschrauben angeordnet sind, mit deren Hilfe der Verbindungsstecker mit den Modulen verbindbar ist.A similar connector is also from the DE 297 03 367 U1 known. This document discloses an electrical device consisting of at least two modules which can be arranged in rows, wherein the individual modules have connection means for connecting sensors or actuators on their upper side. In addition, the individual modules have contact means on their respective longitudinal sides, so that two adjacent modules can be connected to one another with the aid of a connection plug. The connector has a substantially U-shaped housing with two legs, the ends of which can be inserted into the recesses in the modules in which the contact means are arranged. For this purpose, corresponding contact means are formed in the legs of the connector. For mechanical attachment of the connector with the two modules holes are provided at the opposite ends of the legs of the connector in which threaded screws are arranged, with the aid of the connector with the modules is connected.

Zur mechanischen Befestigung der Steckerbaugruppe an der IC-Karte weist die bekannte Steckerbaugruppe einen Verriegelungsmechanismus auf, der insbesondere eine Nockenwelle mit einem Betätigungsgrad und zwei elastische Verriegelungsarme aufweist.The US 5,538,437 A discloses a connector assembly with a cable for electrical connection to an IC card of a computer. For mechanical attachment of the connector assembly to the IC card, the known connector assembly has a locking mechanism, in particular a Has camshaft with a degree of actuation and two elastic locking arms.

Aus der GB 2 338 355 A ist eine Anschlussblockklammer für eine schwimmende Befestigung einer Verbindungsvorrichtung bekannt. Zur einfachen Verbindung mehrerer Verbindungsvorrichtungen mit einem Anschlussblock, in dem mehrere elektrische Schaltungskomponenten angeordnet sind, ist eine Klammer vorgesehen, die mehrere Kammern zur Aufnahme der einzelnen Verbindungsstecker aufweist. Die Klammer ist in eine Abdeckung einsetzbar, die an der Unterseite des Anschlussblocks befestigt wird. Mit Hilfe eines von oben in den Anschlussblock einschraubbaren Bolzens kann die in der Kammer schwimmend angeordnete Verbindungsvorrichtung derart an die Unterseite des Anschlussblocks herangezogen werden, dass die in der Verbindungsvorrichtung angeordneten elektrischen Anschlüsse mit korrespondierenden Gegenkontakten im Anschlussblock kontaktieren.From the GB 2 338 355 A a connection block clamp for a floating attachment of a connection device is known. For easy connection of a plurality of connection devices with a connection block, in which a plurality of electrical circuit components are arranged, a clamp is provided which has a plurality of chambers for receiving the individual connection plugs. The clip is insertable into a cover that attaches to the bottom of the terminal block. With the aid of a bolt which can be screwed into the connection block from above, the connection device arranged floating in the chamber can be used on the underside of the connection block in such a way that the electrical connections arranged in the connection device contact corresponding mating contacts in the connection block.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen eingangs beschriebenen Verbindungsstecker bezüglich der Handhabung und Montage zu verbessern.The present invention has for its object to improve a connector described above with respect to handling and assembly.

Diese Aufgabe ist bei dem eingangs beschriebenen Verbindungsstecker dadurch gelöst, daß das Verriegelungselement mittig zwischen den beiden Gegensteckverbinder angeordnet ist und daß das Verriegelungselement aus einer ersten Stellung, in der der Verbindungsstecker auf die beiden elektrischen Geräte aufsteckbar bzw. von den beiden elektrischen Geräte abnehmbar ist, in eine zweite Stellung verbringbar ist, in der der Verbindungsstecker an den Geräten befestigt ist und die beiden Geräte durch den Verbindungsstecker mechanisch miteinander verbunden sind.This object is achieved with the connector described above in that the locking element is arranged centrally between the two mating connectors and that the locking element from a first position in which the connector on the two electrical devices attachable or is removable from the two electrical devices, can be brought into a second position in which the connector is attached to the devices and the two devices are mechanically connected by the connector.

Abweichend von der ansonsten bei elektrischen Steckverbindungen realisierten mechanischen Verbindungsmöglichkeit mit Hilfe einer Überwurfmutter oder einer Überwurfschraube, die mit dem Gegensteckverbinderteil verschraubt wird, ist bei dem erfindungsgemäßen Verbindungsstecker somit ein separates Verriegelungselement vorgesehen, mit dem der Verbindungsstecker insgesamt am Gehäuse der elektrischen Geräte, insbesondere der Sensor-Aktor-Boxen befestigt werden kann.Notwithstanding the otherwise realized with electrical connectors mechanical connection option by means of a union nut or a cap screw which is bolted to the mating connector part, a separate locking element is thus provided in the connector according to the invention, with which the connector in total on the housing of the electrical equipment, in particular the sensor -Actor boxes can be attached.

Hierbei wird der Umstand ausgenutzt, daß die einzelnen Anschlußstecker im Gehäuse der Sensor-Aktor-Boxen einen gewissen Abstand vom Rand der Sensor-Aktor-Boxen aufweisen, so daß auch die beiden Gegensteckverbinder des Verbindungssteckers einen korrespondierenden Abstand voneinander aufweisen müssen. Dadurch ist zwischen den beiden Gegensteckverbindem ausreichend Platz zur Aufnahme des Verriegelungselements vorhanden, so daß sich die Baugröße des Verbindungssteckers durch die Aufnahme des Verriegelungselements nicht vergrößert.Here, the fact is exploited that the individual connectors in the housing of the sensor-actuator boxes have a certain distance from the edge of the sensor-actuator boxes, so that the two mating connectors of the connector must have a corresponding distance from each other. As a result, there is sufficient space for receiving the locking element between the two Gegensteckverbindem so that the size of the connector does not increase by the inclusion of the locking element.

Durch die Anordnung des Verriegelungselements wird außerdem nicht nur die mechanische Befestigung des Verbindungssteckers auf den Sensor-Aktor-Boxen gewährleistet, sondern darüber hinaus auch eine mechanische Verbindung der beiden Sensor-Aktor-Boxen untereinander hergestellt. Durch die Ausbildung des Verriegelungselements in dem Verbindungsstecker kann somit auf die Ausbildung entsprechender Rastelemente an den Sensor-Aktor-Boxen verzichtet werden. Das Verriegelungselement übernimmt somit eine doppelte Funktion; zum einen die mechanische Befestigung des Verbindungssteckers an den beiden elektrischen Geräten, zum anderen die sichere Befestigung der beiden elektrischen Geräte zueinander.In addition, the arrangement of the locking element not only ensures the mechanical attachment of the connector to the sensor-actuator boxes, but also made a mechanical connection between the two sensor-actuator boxes with each other. Due to the design of the locking element in the connector can thus be dispensed with the formation of corresponding locking elements on the sensor actuator boxes. The locking element thus assumes a double function; on the one hand, the mechanical attachment of the connector to the two electrical devices, on the other hand, the secure attachment of the two electrical devices to each other.

Grundsätzlich könnten zwar auch die beiden Gegensteckverbinder des Verbindungssteckers jeweils eine Überwurfhülse mit einem entsprechenden Gewinde aufweisen, da dann jedoch die Überwurfhülse - im Unterschied zur Ausbildung bei einem elektrischen Kabel mit einem entsprechenden Steckverbinder nur relativ schwer zugänglich wäre, wäre das Auf- bzw. Einschrauben der Überwurfhülse relativ aufwendig. Im Unterschied dazu kann durch eine entsprechende Ausgestaltung des Verriegelungselements die mechanische Befestigung des erfindungsgemäßen Verbindungssteckers an den benachbarten Sensor-Aktor-Boxen sehr einfach realisiert werden.In principle, although the two mating connector of the connector each having a cap sleeve with a corresponding thread, but then the cap sleeve - in contrast to training in an electrical cable with a corresponding connector would be relatively difficult to access, would be the screwing or screwing Cap sleeve relatively expensive. In contrast, by a corresponding configuration of the locking element, the mechanical attachment of the connector according to the invention to the adjacent sensor-actuator boxes can be realized very easily.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist das Verriegelungselement als Schlüsselelement mit einem Zylinderkopf und einem Schlüsselbart ausgebildet, wobei der Schlüsselbart in der ersten Stellung durch eine zwischen den beiden benachbarten elektrischen Geräten ausgebildete Nut durchsteckbar ist und in der zweiten Stellung an den beiden elektrischen Geräten ausgebildete Vorsprünge untergreift. Ein derartiges Schlüsselelement ist nicht nur besonders einfach herstellbar, es läßt sich auch sehr einfach durch Drehen betätigen. Hierzu ist in dem Zylinderkopf des Schlüsselelements vorzugsweise ein Schlitz oder Kreuzschlitz ausgebildet. Damit das Verriegelungselement nicht beschädigt werden kann, ist darüber hinaus vorgesehen, daß das Verriegelungselement im Gehäuse versenkbar ist. Dabei ist vorzugsweise eine Sackbohrung zur Abstützung des Zylinderkopfes im Gehäuse ausgebildet.According to a further preferred embodiment of the invention, the locking element is designed as a key element with a cylinder head and a key bit, wherein the key bit in the first position by a trained between the two adjacent electrical devices groove is pushed through and engages under the projections in the second position formed on the two electrical devices. Such a key element is not only very easy to produce, it can also be very easy to operate by turning. For this purpose, a slot or cross slot is preferably formed in the cylinder head of the key element. So that the locking element can not be damaged, it is also provided that the locking element is retractable in the housing. In this case, preferably a blind bore for supporting the cylinder head is formed in the housing.

Gemäß einer weiteren, besonders bevorzugten Ausgestaltung der Erfindung ist auf den beiden Kontaktträgern der beiden Gegensteckverbinder des Verbindungssteckers jeweils ein Dichtelement angeordnet, mit dessen Hilfe die Verbindung zwischen dem Verbindungsstecker und den Sensor-Aktor-Boxen den Anforderungen der Schutzart IP65 oder IP67 genügt. In der Montagestellung des Verbindungssteckers sind dazu die beiden Dichtelemente der beiden Gegensieckverbinder derart zwischen den beiden Anschlußsteckern der Sensor-Aktor-Boxen und den Gegensteckverbindern angeordnet, daß die Dichtelemente axial zusammengepreßt sind. Aufgrund der Anordnung der Dichtelemente auf den Kontaktträgern ist somit zur Montage des Verbindungsstekkers eine axiale Kraft erforderlich, wobei der Verbindungsstecker anschließend trotz der Rückstellkraft der Dichtelemente aufgrund des Verriegelungselements in seiner Montagestellung verbleibt.According to a further, particularly preferred embodiment of the invention, in each case a sealing element is arranged on the two contact carriers of the two mating connectors of the connector, with the help of which the connection between the connector and the sensor-actuator boxes meets the requirements of protection IP65 or IP67. In the mounting position of the connector to the two sealing elements of the two Gegensieckverbinder are arranged between the two connector plugs of the sensor-actuator boxes and the mating connectors so that the sealing elements are axially compressed. Due to the arrangement of the sealing elements on the contact carriers, an axial force is thus required for mounting the Verbindungsstekkers, the connector then remains in spite of the restoring force of the sealing elements due to the locking element in its mounting position.

Gemäß einer letzten vorteilhaften Ausgestaltung der Erfindung, die hier noch kurz erläutert werden soll, besteht das Gehäuse des Verbindungssteckers aus einem im wesentlichen U-förmig ausgebildeten Unterteil und einem Deckel. Im Deckel ist dabei eine Öffnung zur Betätigung des Verriegelungselements ausgebildet, wobei sich bei der Ausbildung eines einfachen Schlitzes im Zylinderkopf des Verriegelungselements dann der Vorteil ergibt, daß anhand der Ausrichtung des Schlitzes unmittelbar erkennbar ist, ob der Verbindungsstekker richtig verriegelt ist.According to a last advantageous embodiment of the invention, which will be briefly explained here, the housing of the connector consists of a substantially U-shaped lower part and a lid. In the lid while an opening for actuating the locking element is formed, which then results in the formation of a simple slot in the cylinder head of the locking element has the advantage that it is immediately apparent from the orientation of the slot, whether the Verbindungsstekker is properly locked.

Im einzelnen gibt es nun eine Vielzahl von Möglichkeiten, den erfindungsgemäßen Verbindungsstecker auszugestalten und weiterzubilden. Hierzu wird verwiesen sowohl auf die dem Patentanspruch 1 nachgeordneten Patentansprüche als auch auf die Beschreibung eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung.

In allen Figuren dargestellt ist ein Verbindungsstecker 1 und in den Fig. 1 und 2 jeweils ein Teil eines elektrischen Geräts. Der Verbindungsstecker 1 dient dabei zur elektrischen Verbindung eines ersten Anschlußsteckers 2 einer ersten Sensor-Aktor-Box 3 mit einem zweiten Anschlußstecker 4 einer zweiten Sensor-Aktor-Box 5. Die Sensor-Aktor-Boxen 3, 5 weisen darüber hinaus noch weitere Anschlußstecker 6 auf, beispielsweise insgesamt acht Anschlußstecker, von denen in Fig. 1 jedoch nur jeweils ein weiterer Anschlußstecker 6 dargestellt ist.Shown in all figures is a connector 1 and in the Fig. 1 and 2 each a part of an electrical device. The connector 1 is used for electrical connection of a first connector 2 of a first sensor-actuator box 3 with a second connector 4 of a second sensor-actuator box 5. The sensor-actuator boxes 3, 5 also have more connectors. 6 on, for example, a total of eight connectors, of which in Fig. 1 However, only one additional connector 6 is shown.

Der Verbindungsstecker 1 weist ein Gehäuse 7 und zwei in dem Gehäuse 7 parallel zueinander angeordnete Gegensteckverbinder 8, 9 auf, wobei der erste Gegensteckverbinder 8 mit dem ersten Anschlußstecker 2 und der zweite Gegensteckverbinder 9 mit dem zweiten Anschlußstecker 4 verbindbar ist. Die beiden Gegensteckverbinder 8, 9 weisen jeweils einen Kontaktträger 10 mit mehreren als Kontaktstifte 11 ausgebildeten Kontaktelementen auf, die mit den als Kontaktbuchsen 12 ausgebildeten Kontaktelementen der Anschlußstecker 2, 4 verbindbar sind.The connector 1 has a housing 7 and two in the housing 7 mutually parallel mating connector 8, 9, wherein the first mating connector 8 with the first connector 2 and the second mating connector 9 with the second connector 4 is connectable. The two mating connectors 8, 9 each have a contact carrier 10 with a plurality of contact pins 11 formed as contact elements, which are connectable to the trained as contact sockets 12 contact elements of the connector 2, 4.

Bei dem in den Figuren dargestellten Ausführungsbeispiel sind die Anschlußstecker 2, 4 somit als Buchsen ausgebildet, während die Gegensteckverbinder 8, 9 des Verbindungssteckers 1 als Stecker ausgebildet sind. Ebenso ist es jedoch auch möglich, daß die Gegensteckverbinder 8, 9 als Buchsen und dann entsprechend die Anschlußstecker 2, 4 als Stecker mit entsprechenden Kontaktstiften ausgebildet sind. In beiden Fällen kann die elektrische Verbindung der beiden Anschlußstecker 2, 4 einfach durch Aufstecken der Gegensteckverbinder 8, 9 des Verbindungsstecker 1 auf die beiden nebeneinander angeordneten Sensor-Aktor-Boxen 3, 5 hergestellt werden.In the embodiment shown in the figures, the connector 2, 4 are thus formed as sockets, while the mating connectors 8, 9 of the connector 1 are formed as a plug. However, it is also possible that the mating connectors 8, 9 as sockets and then according to the connector 2, 4 are formed as a plug with corresponding contact pins. In both cases, the electrical connection of the two connectors 2, 4 can be made simply by plugging the mating connector 8, 9 of the connector 1 on the two juxtaposed sensor-actuator boxes 3, 5.

Zur sicheren mechanischen Befestigung des Verbindungssteckers 1 an den beiden Sensor-Aktor-Boxen 3, 5 und damit auch zur sicheren mechanischen Befestigung der Gegensteckverbinder 8, 9 mit den Anschlußsteckern 2, 4 ist ein Verriegelungselement 13 vorgesehen, welches in den dargestellten Ausführungsbeispielen als Schlüsselelement ausgebildet ist. Das Verriegelungselement 13 weist dabei einen Zylinderkopf 14 und einen Schlüsselbart 15 auf, wobei das Verriegelungselement 13 insgesamt drehbar in dem Gehäuse 7 des Verbindungssteckers 1 gehalten ist.For secure mechanical attachment of the connector 1 to the two sensor-actuator boxes 3, 5 and thus also for secure mechanical attachment of the mating connectors 8, 9 with the connectors 2, 4, a locking element 13 is provided which is formed in the illustrated embodiments as a key element is. The locking element 13 in this case has a cylinder head 14 and a key bit 15, wherein the locking element 13 is held rotatably in total in the housing 7 of the connector 1.

In der ersten, in Fig. 1 dargestellten Position (Montagestellung) des Verriegelungselements 13 kann der Schlüsselbart 15 durch eine zwischen den beiden benachbart angeordneten Sensor-Aktor-Boxen 3, 5 ausgebildete Nut 16 durchgesteckt werden. Wird das Verriegelungselement 13 anschließend durch eine 90°-Drehung in die zweite Stellung verbracht (Fig. 2) so untergreift der Schlüsselbart 15 zwei an den beiden Sensor-Aktor-Boxen 3, 5 ausgebildete Vorsprünge 17, die seitlich am Gehäuse 18 der Sensor-Aktor-Boxen 3, 5 angeordnet sind und die Nut 16 begrenzen. Soll der Verbindungsstecker 1 wieder entfernt werden, so muß das Verriegelungselement 13 nur erneut um 90° gedreht werden. Der Verbindungsstecker 1 kann dann wieder von den beiden Sensor-Aktor-Boxen 3, 5 abgezogen werden.In the first, in Fig. 1 shown position (mounting position) of the locking element 13, the key bit 15 can be inserted through a groove 16 formed between the two adjacently arranged sensor-actuator boxes 3, 5. If the locking element 13 is then moved by a 90 ° rotation in the second position ( Fig. 2 ) so engages the key bit 15 two formed on the two sensor-actuator boxes 3, 5 projections 17, the side of the housing 18 of the sensor-actuator boxes 3, 5 are arranged and the groove 16 limit. If the connector 1 is to be removed again, then the locking element 13 need only be rotated again by 90 °. The connector 1 can then be deducted again from the two sensor-actuator boxes 3, 5.

Zur einfachen Drehbetätigung des Verriegelungselements 13 ist im Zylinderkopf 14 ein Schlitz 19 ausgebildet, in den die Spitze eines Schraubendrehers eingesteckt werden kann. Dies ermöglicht eine einfache Drehung des vorriegelungselements 13 trotz seiner im Gehäuse 7 versenkten Anordnung, die das Verriegelungselement 13 gegen Beschädigungen schützt. Zur Abstützung und Aufnahme des Verriegelungselements 13 ist dabei in dem Gehäuse 7 eine Sackbohrung 20 ausgebildet. Das mittig zwischen den beiden Gegensteckverbindern 8, 9 im Gehäuse 7 des Verbindungssteckers 1 angeordnete Verriegelungselement 13 ist so klein, daß der aufgrund des notwendigerweise vorhandenen Abstandes zwischen den beiden Gegensteckverbindern 8, 9 vorhandene Platz im Verbindungsstecker 1 völlig ausreichend ist. Die Abmessungen des Verbindungssteckers 1 werden somit durch die Anordnung des Verriegelungselements 13 nicht beeinträchtigt, insbesondere nicht vergrößert.For easy rotational actuation of the locking element 13, a slot 19 is formed in the cylinder head 14, in which the tip of a screwdriver can be inserted. This allows a simple rotation of the locking element 13 despite its recessed in the housing 7 arrangement that protects the locking member 13 against damage. For supporting and receiving the locking element 13 while a blind bore 20 is formed in the housing 7. The centrally disposed between the two mating connectors 8, 9 in the housing 7 of the connector 1 locking element 13 is so small that due to the necessarily existing Distance between the two mating connectors 8, 9 existing space in the connector 1 is completely sufficient. The dimensions of the connector 1 are thus not affected by the arrangement of the locking element 13, in particular not increased.

Wie aus den Fig. 1 und 2 darüber hinaus ersichtlich ist, ist auf den beiden Kontaktträgern 10 der beiden Gegensteckverbinder 8, 9 jeweils ein Dichtring 21 angeordnet. Die beiden Dichtringe 21 sind dabei so dimensioniert und angeordnet, daß sie im montierten Zustand des Verbindungssteckers 1 durch die Anschlußstecker 4, 6 und die beiden Gegensteckverbinder 8, 9 axial zusammengedrückt sind. Die Höhe der Dichtringe 21 ist somit im entspannten Zustand größer als der sich im montierten Zustand des Verbindungssteckers 1 ergebende Freiraum zwischen der Stirnseite der Anschlußstecker 2, 4 und dem Grund der Gegensteckverbinder 8, 9.Like from the Fig. 1 and 2 Moreover, it can be seen, in each case a sealing ring 21 is arranged on the two contact carriers 10 of the two mating connectors 8, 9. The two sealing rings 21 are dimensioned and arranged so that they are axially compressed in the assembled state of the connector 1 by the connector 4, 6 and the two mating connectors 8, 9. The height of the sealing rings 21 is thus greater in the relaxed state than in the assembled state of the connector 1 resulting free space between the end face of the connector 2, 4 and the bottom of the mating connector 8, the ninth

Insbesondere aus der Fig. 4 ist ersichtlich, daß das Gehäuse 7 zweiteilig ausgebildet ist, nämlich ein im wesentlichen U-förmig ausgebildetes Unterteil 22 und einen ebenen Deckel 23 aufweist, Zur Aufnahme des Verriegelungselements 13 ist dabei im Deckel 23 eine Öffnung 24 ausgebildet, durch die das Verriegelungselement 13 in das Unterteil 22 eingesetzt und ein Schraubendreher zum Verdrehen des Verriegelungselements 13 in den Schlitz 19 im Zylinderkopf 14 eingesteckt werden kann. Außer zur Ausbildung der einstückig mit dem Unterteil 22 verbundenen Kontaktträger 10 dient das Unterteil 22 auch zur Aufnahme einer Leiterplatte 25, die mit den Kontaktstiften 11 der Gegensteckverbinder 8, 9 verbunden ist, so daß die elektrische Verbindung zwischen den einzelnen Kontaktstiften 11 der Gegensteckverbinder 8, 9 über auf der Leiterplatte 25 ausgebildete Leiterbahnen realisiert wird. Zum Einstecken des Verriegelungsselements 13 weist auch die Leiterplatte 25 eine der Öffnung 24 entsprechende Öffnung 26 auf.In particular from the Fig. 4 It can be seen that the housing 7 is formed in two parts, namely a substantially U-shaped lower part 22 and a flat cover 23 has, for receiving the locking element 13 while an opening 24 is formed in the cover 23, through which the locking element 13 in the Lower part 22 is inserted and a screwdriver for rotating the locking element 13 in the slot 19 in the cylinder head 14 can be inserted. Except for the formation of the integrally connected to the lower part 22 contact carrier 10, the lower part 22 also serves to receive a printed circuit board 25 which is connected to the contact pins 11 of the mating connector 8, 9, so that the electrical connection between the individual contact pins 11 of the mating connector 8, 9 is realized via formed on the circuit board 25 traces. For insertion of the locking element 13, the circuit board 25 has an opening 26 corresponding to the opening 26.

Am Unterteil 22 des Gehäuses 7 sind außerdem noch zwei die Kontaktträger 10 umgebende zylindrische Außenhülsen 27 angeformt, welche sowohl dem mechanischen Schutz der Kontaktträger 10 als auch zusätzlich der Verbesserung der Dichtigkeit zwischen dem Verbindungsstecker 1 und den beiden Sensor-Aktor-Boxen 3, 5 dienen. Wie aus Fig. 2 ersichtlich ist, sitzen die Stirnseiten der beiden Außenhülsen 27 im montierten Zustand des Verbindungssteckers 1 auf der Oberseite 28 der beiden Sensor-Aktor-Boxen 3, 5 auf.On the lower part 22 of the housing 7 also the contact carrier 10 surrounding cylindrical outer sleeves 27 are also formed, which serve both the mechanical protection of the contact carrier 10 and in addition the improvement of the tightness between the connector 1 and the two sensor-actuator boxes 3, 5 , How out Fig. 2 it can be seen that they are sitting End sides of the two outer sleeves 27 in the mounted state of the connector 1 on the top 28 of the two sensor-actuator boxes 3, 5 on.

Die Anschlußstecker 2, 4 und die Gegensteckverbinder 8, 9 sind vorzugsweise als M12 Steckverbinder ausgebildet, wobei jedoch auch andere Abmessungen, insbesondere M8 möglich sind. Wie insbesondere aus Fig. 3 ersichtlich ist, kann der Deckel 23 zur Aufnahme eines Firmenlogos oder einer Gerätebezeichnung entsprechende Einprägungen oder Aufdrucke aufweisen.The connector 2, 4 and the mating connectors 8, 9 are preferably formed as M12 connector, but other dimensions, in particular M8 are possible. As in particular from Fig. 3 can be seen, the lid 23 for receiving a company logo or a device name corresponding impressions or imprints have.
