Description

Die Erfindung betrifft eine Steckverbindung mit zumindest zwei mittels einer beweglichen Kontaktbrücke elektrisch miteinander verbindbaren Kontaktelementen mit Anschlüssen für einzelne elektrische Leiter einerseits, sowie Steckanschlüssen für Kontakte eines elektrischen Steckverbinders andererseits, wobei die durch die bewegliche Konaktbrücke elektrisch miteinander verbundenen Kontaktelemente beim Einführen des Gegensteckers durch Ausübung eines Drukkes auf die bewegliche Kontaktbrücke elektrisch getrennt werden.The invention relates to a plug connection with at least two contact elements which can be electrically connected to one another by means of a movable contact bridge, with connections for individual electrical conductors on the one hand, and plug connections for contacts of an electrical connector on the other hand, the contact elements electrically connected to one another by the movable contact bridge when the mating connector is inserted by exercising a Drukkes on the movable contact bridge are electrically separated.

Bei derartigen Steckverbindungen ist es erforderliche, eine Betätigungseinrichtung für die Kontaktbrücke so auszubilden, daß die, bei nicht eingeführtem Gegenstecker elektrisch durch die Kontaktbrücke verbundenen Kontaktelemente, beim Einführen des Gegensteckers elektrisch getrennt werden. Dabei ist es weiterhin nötig, die Betätigungseinrichtung so auszubilden, daß die Trennung der elektrischen Verbindung zwischen den Kontaktelementen erst dann erfolgt, wenn die Kontaktelemente bereits elektrisch mit den Steckanschlüssen des Gegensteckers verbunden sind. Dies ist beispielsweise erforderlich, wenn in elektrischen Stromkreisen elektromagnetische Stromwandler mit zu- und abschaltbaren Meßeinrichtungen vorgesehen sind, da derartige Stromwandler sekundäseitig niemals mit offenen Klemmen betrieben werden dürfen, da sonst unter Umständen sehr hohe Induktionspannungen entstehen können, die zur Zerstörung der Wandler führen können.In the case of such plug connections, it is necessary to design an actuating device for the contact bridge in such a way that the contact elements which are electrically connected by the contact bridge when the mating connector is not inserted are electrically isolated when the mating connector is inserted. It is also necessary to design the actuating device such that the electrical connection between the contact elements is only separated when the contact elements are already electrically connected to the plug connections of the mating connector. This is necessary, for example, when electromagnetic current transformers with measuring devices that can be switched on and off are provided in electrical circuits, since such current transformers may never be operated with open terminals on the secondary side, since otherwise very high induction voltages can arise which can lead to the destruction of the transformers.

Andererseits sind derartige Steckverbindungen auch erforderlich, wenn betriebsmäßig Strommeßeinrichtungen oder andere Einrichtungen in elektrische Stromkreise eingeschaltet werden sollen, die aus betriebsmäßigen Gründen keine Unterbrechung des fließenden Stromes erfahren dürfen.On the other hand, plug connections of this type are also required if operationally current measuring devices or other devices are to be switched into electrical circuits which, for operational reasons, must not experience an interruption in the flowing current.

Bei einer bekannten Steckvorrichtung dieser Art (DE-C-18 02 457) ist vorgesehen, daß die Kontaktbrücke aus mehreren federnd gelagerten Kontaktgliedern besteht und daß an dem Gegenstecker ein Betätigungsglied vorgesehen ist, das beim Einführen des Steckers in die Steckerfassung einen Druck auf die Kontaktglieder ausübt. Diese Anordnung erfüllt die Erfordernisse im großen und ganzen zufriedenstellend. Jedoch ist bei der bekannten Steckvorrichtung für jeden Anwendungsfall (Anzahl der schaltbaren Kontakte) eine speziell, separat herzustellende Steckverbindung (Gehäuse, Gegenstecker) erforderlich, die im übrigen aus einer Vielzahl von verschiedenartigen, in fester Zuordnung zueinander verbundenen Einzelteilen besteht. Eine universelle Anordnung bzw. Umstellung für verschiedenartige Verwendung, wie beispielsweise schaltbare Verbindung nur zweier Strompfade und Verwendung der restlichen Kontakte als normale Steckverbindungskontakte ist hier nicht vorgesehen und bei dem vorgegebenen Aufbau auch nicht wirtschaftlich herstellbar. Weiterhin erfolgt die Betätigung der federnden Kontaktglieder über am Gegenstecker fest angeordnete Betätigungsglieder. Es ist somit für den jeweiligen Anwendungsfall jeweils ein spezieller Gegenstekker erforderlich.In a known plug device of this type (DE-C-18 02 457) it is provided that the contact bridge consists of a plurality of spring-mounted contact members and that an actuating member is provided on the mating connector which presses the contact members when the plug is inserted into the socket exercises. This arrangement largely satisfies the requirements. However, in the known plug-in device for each application (number of switchable contacts), a special plug connection (housing, mating plug) to be produced separately is required, which, moreover, consists of a large number of different types of individual parts which are connected to one another in a fixed association. A universal arrangement or conversion for various uses, such as, for example, switchable connection of only two current paths and use of the remaining contacts as normal plug-in connection contacts, is not provided here and, in the given structure, is also not economical to produce. Furthermore, the resilient contact members are actuated via actuating members fixedly arranged on the mating connector. A special mating connector is therefore required for each application.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die o.g. Nachteile zu überwinden und eine Steckverbindung der eingangs genannten Art zu schaffen, die aus wenigen verschiedenartigen Grundteilen modular aufgebaut ist um somit die Anfertigung und Lagerhaltung einer Vielzahl von unter schiedlichen Einzelteilen zu vermeiden.The present invention is therefore based on the object, the above. To overcome disadvantages and to create a plug connection of the type mentioned, which is modularly constructed from a few different basic parts in order to avoid the manufacture and storage of a multitude of different individual parts.

Diese Aufgabe wird gemäss der Erfindung bei einer Steckverbindung der eingangs genannten Art dadurch gelöst,

  • a) daß der die Steckbuchsen aufweisende Steckdoseneinsatz aus einem Steckbuchsenträger und modular aneinandergereihten, mit Kontakt- bzw. Betätigungseinrichtungen versehenen, scheibenförmigen Elementen, die auf den Steckbuchsenträger aufgerastet sind, besteht,
  • b) daß der die Kontaktelemente bzw. Betätigungseinrichtungen aufnehmende und halternde Isolierkörper der scheibenförmigen Elemente aus kongruenten Isolierscheiben zusammengesetzt ist, wobei der Isolierkörper mit seitlichen Rastarmen zur rastbaren Befestigung an dem mit entsprechenden Rastschultern versehenen Steckbuchsenträger versehen ist,
  • c) daß die Kontaktelemente des Schaltelemente aufweisenden scheibenförmigen Elementes unter Bildung einer Kontaktbrücken-Auflageschulter gebogen sind und in Aufnahme-Ausnehmungen der Isolierscheiben eingefügt und formschlüssig gehalten sind und
  • d) daß dieses scheibenförmige Element eine mit einer Druckfeder versehene, elektrisch leitende, bewegliche Kontaktbrücke für die zu verbindenden Kontaktelemente aufweist,
  • e) daß zumindest ein scheibenförmiges Element vorgesehen ist, das mit einem in seinem Innenraum längsverschiebbar angeordneten Betätigungsteil versehen ist, wobei das Betätigungsteil stiftförmige Ansätze aufweist, die durch die Führungsöffnungen in die Öffnungen des Steckbuchsenträgers ragen, und
  • f) daß über ein sich quer durch die scheibenformigen Elemente erstreckendes, elektrisch nicht leitendes Druckübertragungselement ein Druck auf die bewegliche Kontaktbrücke beim Einstekken des Gegensteckers ausgeübt wird, wobei die Einleitung des Druckes dadurch erfolgt, daß die im Bereich des Betätigungsteiles liegenden Stekkerstifte beim Zusammenstecken das Betätigungsteil niederdrücken.
This object is achieved according to the invention in a plug connection of the type mentioned at the outset,
  • a) that the socket insert comprising the sockets consists of a socket holder and modular, lined-up, provided with contact or actuating devices, disk-shaped elements which are snapped onto the socket holder,
  • b) that the insulating body receiving and holding the contact elements or actuating devices of the disk-shaped elements is composed of congruent insulating disks, the insulating body being provided with lateral latching arms for latching attachment to the socket carrier provided with corresponding latching shoulders,
  • c) that the contact elements of the switching element-containing disc-shaped element are bent to form a contact bridge support shoulder and are inserted in receptacle recesses of the insulating washers and held in a form-fitting manner and
  • d) that this disk-shaped element has an electrically conductive, movable contact bridge provided with a compression spring for the contact elements to be connected,
  • e) that at least one disk-shaped element is provided, which is provided with an actuating part arranged longitudinally displaceably in its interior, the actuating part having pin-shaped projections which protrude through the guide openings into the openings of the socket carrier, and
  • f) that a pressure is exerted on the movable contact bridge when the mating connector is inserted, across an electrically non-conductive pressure transmission element extending across the disk-shaped elements, the pressure being introduced in that the plug pins lying in the area of the actuating part are used to plug the actuating part together Press down.

Die vorteilhaften Weiterbildungen der erfindungsgemäßen Steckvorrichtung sind in den abhangigensprüchen 2 bis 4 beschrieben.The advantageous developments of the plug device according to the invention are described in dependent claims 2 to 4.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß eine universell verwendbare Steckverbindung geschaffen wurde, die aufgrund ihres modularen Aufbaues aus wenigen verschiedenartigen Grundteilen zusammengestellt werden kann, wobei durch die somit mögliche rationelle Serienfertigung der Grundteile eine äußerst preisgünstige Steckverbindung hergestellt werden kann. Weiterhin ist es durch den modularen Aufbau problemlos möglich, Steckverbindungen zu erstellen, die bei Verwendung der gleichen Grundteile neben den schaltbaren Kontakten auch normale Steckverbindungskontakte enthält. Dabei kann der Aufbau einer derartigen Steckverbindung ggf. vom Anwender selbst vorgenommen werden. Ein weiterer Vorteil liegt darin, daß als Gegenstecker ein für alle verschiedenen Arten von Steckverbindungen (nur Schaltkontäkte, Schaltkontakte und Normalkontakte, nur Steckverbinderkontakte) ein gleichartig ausgebildeter Gegenstecker Anwendung finden kann. Dabei ist vorzugsweise vorgesehen, daß der Steckbuchsenträger des Steckdoseneinsatzes so ausgebildet ist, daß ein handelsüblicher, auch bereits für vorhandene Steckvorrichtungen verwendeter Gegenstecker verwendet werden kann. Eine Herstellung und Lagerhaltung von verschiedenartigen Gegensteckern erübrigt sich somit, wodurch eine weitere Reduzierung der Kosten für derartige Steckverbindungen erzielt wird.The advantages achieved by the invention consist in particular in the fact that a universally usable plug-in connection has been created, which, owing to its modular structure, can be put together from a few different basic parts, with the result that possible rational series production of the basic parts an extremely inexpensive connector can be made. Furthermore, thanks to the modular structure, it is possible to create plug-in connections that, when using the same basic parts, also contain normal plug-in contacts in addition to the switchable contacts. The plug-in connection can be set up by the user himself if necessary. Another advantage is that a mating connector of the same design can be used as a mating connector for all different types of plug connections (only switching contacts, switching contacts and normal contacts, only connector contacts). It is preferably provided that the socket carrier of the socket insert is designed so that a commercially available mating connector, which is already used for existing plug devices, can be used. A production and storage of different types of mating connectors is therefore superfluous, as a result of which a further reduction in the costs for such connectors is achieved.

Der Kontaktbuchsenträger ist weiterhin mit seitlichen Laschen 11 und den Befestigungsschrauben 12 zur schraubbaren Befestigung im Steckdosengehäuse 2 versehen. Nach dem Zusammenstecken der Steckverbindung ist diese über die am Steckdosengehäuse angeordneten Rastbügel 13 und die am Steckergehäuse vorgesehenen Verriegelungszapfen 14 in an sich bekannter Weise verriegelbar. Die Elemente 10, 10', 10" sind mit stirnseitigen Rastarmen 15 versehen, die hinter entsprechenden Rastschultern 16 des Steckbuchsenträgers 9 verrastet sind und die Verbindung der Elemente mit dem Steckbuschsenträger bewirken.The socket insert 1 consists essentially of the contact socket support 9 provided with guide bores 8 for receiving the contact sockets or the switching pins and the elements 10, 10 ', 10 "provided with the contact devices. The contact socket support is furthermore provided with side tabs 11 and the fastening screws 12 provided with screwable fastening in the socket housing 2.

In den Fig. 2 bis 4 ist der Aufbau der einzelnen Elemente im einzelnen dargestellt. Jedes Element 10, 10' besteht aus zwei kongruenten, halbschalenförmigen Isolierscheiben 17, die nach dem Einfügen der jeweiligen Kontaktteile gegeneinandergepreßt werden und mittels der Zapfen 18, die in entsprechende Aufnahme-Ausnehmungen 19 des Gegenteiles klemmend eintauchen, fest miteinander verbunden.2 to 4, the structure of the individual elements is shown in detail. Each element 10, 10 'consists of two congruent, half-shell-shaped insulating washers 17 which are pressed against one another after the insertion of the respective contact parts and are firmly connected to one another by means of the pins 18 which plunge into corresponding receptacle recesses 19 of the opposite.

In den Fig. 2 und 3 ist der innere Aufbau eines Schaltkontaktelementes 10 näher dargestellt. Die der Stromleitung dienenden Kontaktelemente 20 bestehen aus den Kontaktbuchsen 21, die mit sich in den Innenraum des Elementes erstreckenden flachen Stromschienen 22 versehen sind, die an den den Kontaktbuchsen gegenüberliegenden Enden mit Einrichtungen zum Anschluß eines elektrischen Leiters, hier Federklemmen 23, versehen sind. Die Stromschienen sind weiterhin in ihrem mittleren Bereich mit einer Abbiegung 24 versehen, die eine Auflageschulter 25 für die längsbewegliche Kontaktbrücke 26 bildet. Die Kontaktbrücke selbst ist mit einem stiftförmigen Ansatz 27, auf dem sich die Druckfeder 28 befindet, versehen. Die Seitenwände der Isolierscheiben 17 sind mit einer Öffnung 29 versehen, durch die das Druckübertragungselement 30 bei der späteren Gesamtmontage geführt wird.2 and 3, the inner structure of a switch contact element 10 is shown in more detail. The power elements serving contact elements 20 consist of the contact sockets 21, which are provided with flat conductor rails 22 extending into the interior of the element, which are provided at the ends opposite the contact sockets with devices for connecting an electrical conductor, here spring clips 23. The busbars are also provided in their central region with a bend 24, which forms a support shoulder 25 for the longitudinally movable contact bridge 26. The contact bridge itself is provided with a pin-shaped extension 27 on which the compression spring 28 is located. The side walls of the insulating washers 17 are provided with an opening 29 through which the pressure transmission element 30 is guided during the subsequent overall assembly.

Weiterhin sind die Stirnseiten der Elemente 10 mit einer Öffnung 36 versehen, hinter der die Stromschiene 22 mit einer in diesem Bereich angeordneten Gewindebohrung 37 verläuft. Dadurch ist die Möglichkeit gegeben, im Bedarfsfalle einzelne Kontaktelemente 20 mittels einer äußeren Querschiene 38 durch eine eingeschraubte Schraube 40 miteinander elektrisch zu verbinden.Furthermore, the end faces of the elements 10 are provided with an opening 36, behind which the busbar 22 runs with a threaded bore 37 arranged in this area. This provides the possibility of electrically connecting individual contact elements 20 to one another by means of an outer cross rail 38 by means of a screwed-in screw 40 if necessary.

Der Vollständigkeit halber sei hier nochmals erwähnt, sofern aus den Zeichnungen nicht ohnehin ersichtlich, daß beide Kontaktteile lemente 20 gleichartig ausgebildet sind und daß die ebenfalls gleichartigen Isolierscheiben mit inneren Vorsprüngen und Schlitzen zum geführten Aufnehmen und Haltern der Kontaktteile versehen sind.For the sake of completeness, it should be mentioned here again, unless the drawings show that the two contact parts elements 20 are of identical design and that the likewise identical insulating washers are provided with internal projections and slots for guided receiving and holding of the contact parts.

In der Fig. 4 ist der Aufbau des die Schaltfunktion bewirkenden Elementes 10' näher dargestellt. Dieses Element besteht ebenfalls aus den beiden halbschalenförmigen Isolierscheiben 17, wobei anstelle der Kontaktteile, ein mit zwi stiftförmigen Ansätzen 31 versehenes, längsbewegliches Betätigungsteil 32 in die Halbschalen eingefügt ist. Dabei ragen die stiftförmigen Ansätze 31 durch die sonst der Kontaktbuchsenführung dienenden Öffnungen 39 aus der Oberseite des Elementes 10' hervor. Im Inneren der Halbschalen angeordnete Führungsstege, die hier nicht näher dargestellt sind, ermöglichen ein geführtes Hin-und Hergleiten des Betätigungsteiles. Das Betätigungsteil wirkt auf das bei der Endmontage seitlich durch die Öffnungen 29 geführte Druckübertragungselement 30, so daß beim Niederdrücken des Betätigungsteiles, über das Druckübertragungselement, die Kontaktbrücke entgegen die Kraft der Feder 28 bewegt wird und die Kontaktbrücke 26 aus der die beiden Kontaktteile 20 kurzschließenden Stellung bewegt wird.4 shows the structure of the element 10 'which effects the switching function. This element also consists of the two half-shell-shaped insulating washers 17, a longitudinally movable actuating part 32 being inserted into the half-shells instead of the contact parts, provided with pin-shaped projections 31.

Guide webs arranged in the interior of the half-shells, which are not shown in more detail here, enable the actuating part to be guided back and forth. The actuating part acts on the final assembly pressure transmission element 30 guided laterally through the openings 29, so that when the actuating part is depressed, the contact bridge is moved counter to the force of the spring 28 via the pressure transmission element and the contact bridge 26 is moved from the short-circuiting position of the two contact parts 20.

Bei der Montage des Steckdoseneinsatzes 1 werden die einzelnen Elemente 10, 10', 10" zunächst aneindergereiht, wobei sie mittels an den Seitenflächen angeordneten Zapfen 33 und Ausnehmungen 34 in gegenseitiger Lage zueinander gehalten sind. Anschließend wird in diesen Block in Querrichtung durch die Öffnungen 29 das Druckübertragungselement 30 eingeführt. Sodann wird der gesamte Block auf den Steckbuchsenträger 9 aufgerastet, wobei die Kontaktbuchsen 21, wie auch die stiftförmigen Ansätze 31 des Betätigungsteiles 32 in die Führungsbohrungen 8 des Steckbuchsenträgers gelangen. Der Steckbuchsenträger 9 ist mit seitlich angeformten Ansätzen 35 versehen, die in ihrer Höhe so bemessen sind, daß sie die Öffnungen 29 nach dem Aufrasten des Blockes abdecken und ein Herausgleiten des Druckübertragungselementes 30 aus dem Block verhindern. Zur elektrischen Verbindung einzelner Kontakte der Steckvorrichtung wird ggf. anschließend die Verbindungsschiene 38 in die seitliche Ausnehmung 41 der Elemente 10, 10', 10" eingefügt und die miteinandert zu verbindenden Kontakte werden durch eine in die jeweilige Stromschiene 20 eingedschraubte Schraube 40 mit der Verbindungsschiene elektrisch leitend verbunden.When assembling the socket insert 1, the individual elements 10, 10 ', 10 "are first lined up, being held in mutual relationship with one another by means of pins 33 and recesses 34 arranged on the side surfaces. Then, in this block, openings 29 are made in the transverse direction the pressure transmission element 30. The entire block is then snapped onto the socket carrier 9, the contact sockets 21, as well as the pin-shaped projections 31 of the actuating part 32, coming into the guide bores 8 of the socket carrier 9. The socket carrier 9 is provided with laterally formed projections 35, which are dimensioned in such a way that they cover the openings 29 after the block has been snapped on and prevent the pressure transmission element 30 from sliding out of the block. For the electrical connection of individual contacts of the plug-in device, the connecting rail 38 is then optionally inserted into the lateral recess 41 of the elements te 10, 10 ', 10 "inserted and the contacts to be connected to one another are electrically conductively connected to the connecting rail by a screw 40 screwed into the respective busbar 20.

Durch die gleichartige äussere Ausbildung der einzelnen Elemente 10, 10', 10" können die Elemente in unterschiedlichen Kombinationen Anwendung finden. Imvorliegenden Beispiel gemäß Fig. 1 sind insgesamt 8 Elemente aneinandergereiht, wobei die linken drei Elemente als reine Steckverbindungselemente 10" verwendet sind. Reine Steckverbindungselemente erhält man dadurch, daß in diesen Elementen bei der Montage die Schaltbrücke 26 nicht eingesetzt wird. Das 4., 6. und 8. Element (von links gesehen) ist als Schaltelement 10 mit eingesetzten Steckkontakt- . teilen 20 und der Schaltbrücke 26 ausgebildet und das 5. und 7. Element ist als Betätigungselement 10' mit eingefügtem Betätigungsteil 32 ausgebildet. Im vorliegenden Falle sind zwei Betätigungselement 10' verwendet worden, un einen gleichmäßigen Druck auf das Druckübertragungselement 30 zu erzielen (Verhindern des Verkantens). Es ist jedoch ebensogut bei symmetrischer Anordnung der Schaltelemente möglich und im Bereich der Erfindung liegend, nur ein Betätigungselement in mittiger Anordnung zwischen den Schaltelementen vorzusehen.Due to the similar external design of the individual elements 10, 10 ', 10 ", the elements can be used in different combinations. In the present example according to FIG. 1, a total of 8 elements are strung together, the left three elements being used as pure connector elements 10". Pure connector elements are obtained in that the switching bridge 26 is not used in these elements during assembly. The 4th, 6th and 8th element (seen from the left) is a switching element 10 with inserted plug contact. share 20 and the switching bridge 26 formed and the 5th and 7th element is designed as an actuating element 10 'with inserted actuating part 32. In the present case, two actuating elements 10 'have been used in order to achieve a uniform pressure on the pressure transmission element 30 (prevention of canting). However, with a symmetrical arrangement of the switching elements and within the scope of the invention, it is equally possible to provide only one actuating element in a central arrangement between the switching elements.

Beim einstecken des Gegensteckers der Steckverbindung drücken nun die Kontaktstifte des Steckers die den Betätigungselementen 10' zugeordnet sind auf die stiftförmigen Ansätze 31 des Betätigungsteiles 32 und üben einen Druck auf das Druckübertragungselement 30 aus, wodurch wiederum die Kontaktbrücke 26 gegen die Kraft der Feder 28 von den Kontaktschultern 25 der Stromschienen 20 weggedrückt wird und der Kut-zschluß der bieden Kontakte dieses Elementes aufgehoben wird. Dabei ist durch die Länge der stiftförmigen Ansätze dafür Sorge getragen, daß die Aufhebung des Kurzschlusses erst dann erfolgt, wenn die Kontaktstifte des Steckverbinders bereits mit den Kontaktbuchsen in elektrischen Kontakt gelangt sind. Dabei ist eine Änderung des Schaltzeitpunktes der Kontaktbrücke durch Längenvariation der stiftförmigen Ansätze 31 des Betätigungsteiles 32 problemlos möglich.When inserting the mating connector of the plug connection, the contact pins of the connector which are assigned to the actuating elements 10 'now press onto the pin-shaped projections 31 of the actuating part 32 and exert pressure on the pressure transmission element 30, which in turn causes the contact bridge 26 against the force of the spring 28 from the contact shoulders 25 of the busbars 20 is pushed away and Kut - zschluß bieden the contacts of this element is removed. The length of the pin-shaped lugs ensures that the short circuit is only removed when the contact pins of the connector have already come into electrical contact with the contact sockets. A change in the switching time of the contact bridge is easily possible by varying the length of the pin-shaped lugs 31 of the actuating part 32.
