Description

Elektrische Steckvorrichtung Electrical connector
Die vorliegende Erfindung bezieht sich auf eine elektrische Steckvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an electrical plug device according to the preamble of claim 1.
Steckvorrichtung, welche schraubenlose Anschlussklemmen aufweisen sind bekannt. Solche Anschlussklemmen haben die Aufgabe, im Inneren einer elektrischen Steckvorrichtung, also eines Steckers, einer Kupplung oder einer Steckdose, einerseits die elektrischen Anschlussleitungen in ihrer Position zu halten und andererseits einen Kontakt zwischen den Anschlussleitungen und den elektrisch leitenden Kontaktbauteilen, die in weiterer Folge mit einem Steckerstift in Verbindung bringbar sind bzw. stehen, zu ermöglichen.Plug devices which have screwless connecting terminals are known. Such connection terminals have the task of holding the electrical connection lines in their position on the one hand in the interior of an electrical plug-in device, i.e. a plug, a coupling or a socket, and on the other hand a contact between the connection lines and the electrically conductive contact components, which subsequently result in a Connector pin can be connected or stand, to allow.
Bei diesen schraublosen Anschlussklemmen erfolgt die Klemmung mittels Federkraft einer Anschlusskiemme, welche einen federnd abstehenden Klemmschenkel aufweist, der die elektrischen Anschlussleitungen gegen einen Kontaktbauteil klemmt bzw. gegen einen Teil von sich selbst, wobei dieser Teil wiederum mit dem Kontaktbauteil in elektrisch leitender Verbindung steht .In these screwless connection terminals, the clamping is carried out by means of the spring force of a connecting jaw which has a resiliently projecting clamping leg which clamps the electrical connection lines against a contact component or against a part of itself, this part in turn being in an electrically conductive connection with the contact component.
Solche schraubenlosen Anschlussklemmen befinden sich dabei meistens im entspannten Zustand im Gehäuse der elektrischen Steckvorrichtung, das heißt, dass Klemmen der Anschlussleitung ist in diesem Zustand nicht möglich. Der Benutzer muß erst den federnd abstehenden Klemmschenkel manuell vorspannen, die Anschlussleitung durch eine in der elektrischen Steckvorrichtung befindlicheSuch screwless connection terminals are usually in the relaxed state in the housing of the electrical plug device, that is to say that the connection line cannot be clamped in this state. The user first has to manually pretension the resiliently protruding clamping leg, the connecting line through one located in the electrical plug device
Leitungseinführungsöffnung stecken und dann die Vorspannung wieder lösen, sodass der federnd Klemmschenkel seine Klemmkraft auf die elektrische Anschlussleitung übertragen kann. Die manuelle Vorspannung erfolgt in der Praxis mittels eines dünnen, stiftförmigen Gegenstandes, beispielsweise einem Schraubendreher. Dieser wird in eine entsprechende Öffnung im Gehäuse der elektrischen Steckvorrichtung gesteckt, um den federnden Klemmschenkel soweit zu verschieben, bis ein am Klemmschenkel angeordnetes Anschlussfenster zum Durchstecken der elektrischen Anschlussleitung freigegeben wird. Nach Einschieben der Anschlussleitung durch eine dafür vorgesehene Öffnung im Gehäuse kann der Schraubendreher wieder entfernt werden und der federnde Klemmschenkel klemmt die Anschlussleitung wie oben beschrieben.Insert the cable entry opening and then release the pretension so that the resilient clamping leg can transmit its clamping force to the electrical connection cable. Manual pretensioning is carried out in practice by means of a thin, pen-shaped object, for example a screwdriver. This is inserted into a corresponding opening in the housing of the electrical plug device, around which to move the resilient clamping leg until a connection window arranged on the clamping leg is released for pushing through the electrical connecting line. After inserting the connecting cable through an opening provided in the housing, the screwdriver can be removed and the resilient clamping leg clamps the connecting cable as described above.
Nachteil dabei ist jedoch die Tatsache, dass der Klemmvorgang sehr umständlich ist, da einerseits der federnde Klemmschenkel mittels Schraubendreher in seiner Position gehalten werden muss, andererseits die Anschlussleitung in das Gehäuse eingeführt werden muss. Ein weiterer Nachteil ist der umständliche, mechanische Aufbau des aus dem Gehäuse geführten Hebels, welcher auch zu einem erhöhten Gewicht des Steckers beiträgt .The disadvantage here, however, is the fact that the clamping process is very cumbersome, since on the one hand the resilient clamping leg must be held in position by means of a screwdriver, and on the other hand the connecting line must be inserted into the housing. Another disadvantage is the cumbersome, mechanical structure of the lever guided out of the housing, which also contributes to an increased weight of the connector.
Aus diesem Grund wurden schraubenlose Anschlussklemmen entwickelt, deren federnd abstehender Klemmschenkel mit dem Kontaktbauteil oder dem Gehäuse der elektrischen Steckvorrichtung verrastbar ist. Auf diese Art und Weise kann die Anschlussklemme vorgespannt werden, dass Gehäuse der elektrischen Steckvorrichtung verschlossen werden und es muss zum Klemmen der Anschlussleitungen dann lediglich die Vorspannung mittels Schraubendreher oder eines anderen spitzen Gegenstandes, der in das Gehäuse der elektrischen Steckvorrichtung einführbar ist, gelöst werden. Ein solches System ist beispielsweise aus der DE 33 02 372 AI bekannt.For this reason, screwless connecting terminals have been developed, the resiliently projecting terminal legs of which can be latched to the contact component or the housing of the electrical plug device. In this way, the connecting terminal can be pretensioned so that the housing of the electrical plug-in device is closed, and then only the pretension has to be released by means of a screwdriver or another pointed object that can be inserted into the housing of the electrical plug-in device in order to clamp the connecting lines. Such a system is known for example from DE 33 02 372 AI.
Nachteilig dabei ist jedoch, dass zum Lösen der Anschlussklemme aus ihrer Vorspannung und Klemmen der Anschlussleitung ein zusätzlicher Gegenstand erforderlich ist, der in das Gehäuse der elektrischen Steckvorrichtung eingeschoben werden muss . Falls ein solcher Gegenstand nicht zur Hand ist, kann die Anschlussleitung nicht geklemmt werden. Zwar schlägt die DE 33 02 372 AI auch einen umständlichen, im Inneren des Gehäuses gelagerten und aus dem Gehäuse herausgeführten Hebelmechanismus vor, um die Arretierung zu lösen, jedoch kompliziert die Installation eines solchen Mechanismus die Herstellung einer einfachen Steckdose erheblich und trägt außerdem, insbesondere bei mehreren zu lösenden • federnden Klemmschenkel zu einer unerwünschten Gewichtserhöhung bei.The disadvantage here, however, is that an additional object is required to release the connection terminal from its pretension and to clamp the connection line, which must be inserted into the housing of the electrical plug device. If such an object is not at hand, the connecting cable cannot be clamped. Although DE 33 02 372 AI also proposes a cumbersome lever mechanism, which is mounted inside the housing and extends out of the housing, in order to release the locking mechanism, the installation of such a mechanism complicates the manufacture of a simple socket considerable and also contributes to an undesirable increase in weight, in particular in the case of a plurality of • resilient clamping legs.
Es ist daher eine Aufgabe der vorliegenden Erfindung, diese Nachteile zu vermeiden und elektrische Steckvorrichtung vorzusehen, bei welcher die Klemmung der Anschlussleitung ohne zusätzliches Werkzeug vorgenommen werden kann, wobei gleichzeitig keine Gewichtszunahme der Steckvorrichtung erfolgt .It is therefore an object of the present invention to avoid these disadvantages and to provide electrical plug-in devices in which the connection line can be clamped without additional tools, and at the same time there is no increase in weight of the plug-in device.
Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, this is solved by the characterizing features of claim 1.
Dadurch kann die federnde Anschlussklemme durch Druck auf einen Bereich des Gehäuses aus ihrer vorgespannten Position in ihre Klemmstellung gebracht werden. Ein zusätzliches Werkzeug ist nicht mehr erforderlich. Die elektrische Steckvorrichtung kann auf einfache Art und Weise beispielsweise als einteiliges Spritzgussstück gefertigt werden.As a result, the resilient connecting terminal can be brought from its pretensioned position into its clamping position by pressure on an area of the housing. An additional tool is no longer required. The electrical plug-in device can be manufactured in a simple manner, for example as a one-piece injection molding.
Durch die kennzeichnenden Merkmale des Anspruchs 2 kann die federnde Anschlussklemme in Inneren des Gehäuses der elektrischen Steckvorrichtung wieder arretiert werden.Due to the characterizing features of claim 2, the resilient terminal in the interior of the housing of the electrical connector can be locked again.
Im folgenden folgt nun eine Beschreibung einer erfindungsgemäßen elektrischen Steckvorrichtung anhand eines Ausführungsbeispiels. Dabei zeigt:The following is a description of an electrical plug device according to the invention using an exemplary embodiment. It shows:

In Fig.l und Fig.2 weist der Kontaktbauteil 1 einen Kontaktbereich 3 für die Kontaktierung mit einem Kontaktstift eines Steckers (nicht gezeichnet) auf, sowie einen Anschlussbereich 4, auf den sich die federnde Anschlussklemme 2 mit der Basisebene 5 abstützt. Die federnde Anschlussklemme 2 weist im vorliegenden Beispiel zwei von der Basisebene 5 federnd abstehende Klemmschenkel 2a, 2b auf, die über eine Biegung 6 im wesentlichen rechtwinkelig zur Basisebene 5 der federnden Anschlussklemme 2 angeordnet sind. Die Erfindung beschränkt sich jedoch nicht auf Anschlussklemmen mit zwei Klemmeschenkeln sondern ist auch bei Anschlussklemmen mit nur einem Klemmschenkel oder aber mehr als zwei Klemmschenkel realisierbar. Jeder federnd abstehende Klemmteil 2a, 2b weist weiters ein Anschlussfenster 7 auf und besitzt eine Öffnung 8, die beispielsweise durch Stanzung hergestellt werden kann. Ist die Öffnung 8 am Rasthaken 10 des Kontaktbauteils 1 eingehängt, so befindet sich die federnde Anschlussklemme 2 in vorgespanntem Zustand.In Fig.l and Fig.2, the contact component 1 has a contact area 3 for contacting a contact pin of a plug (not shown), and a connection area 4, on which the resilient terminal 2 is supported with the base plane 5. In the present example, the resilient connecting terminal 2 has two clamping legs 2a, 2b which project resiliently from the base plane 5 and which are arranged at a bend 6 essentially at right angles to the base plane 5 of the resilient connecting terminal 2. However, the invention is not limited to connecting terminals with two terminal legs, but can also be implemented with connecting terminals with only one terminal leg or more than two terminal legs. Each resiliently projecting clamping part 2a, 2b further has a connection window 7 and has an opening 8, which can be produced, for example, by punching. If the opening 8 is hooked onto the latching hook 10 of the contact component 1, the resilient connecting terminal 2 is in the pretensioned state.
Fig.3 zeigt eine erfindungsgemäße elektrische Steckvorrichtung in Form eines Dosengehäuseteils 12, wie es beispielweise bei Steckdosen zum Einsatz kommt. Der Dosengehäuseteil 12 ist mit Leitungsdurchführungsöffnungen 16 versehen, durch welche die Adern der elektrischen Anschlussleitungen in das Doseninnere geführt werden, sowie mit Öffnungen 16a deren Funktion noch später beschrieben wird. Zusätzlich sind am Dosengehäuseteil 12 erfindungsgemäße Bedienelemente 15 angeordnet auf deren Funktionsweise ebenfalls später eingegangen wird.3 shows an electrical plug-in device according to the invention in the form of a socket housing part 12, as is used for example in sockets. The socket housing part 12 is provided with line lead-through openings 16, through which the wires of the electrical connecting lines are guided into the interior of the socket, and with openings 16a, the function of which will be described later. In addition, control elements 15 according to the invention are arranged on the can housing part 12, the functioning of which will also be discussed later.
In der Unteransicht des Dosengehäuseteils 12 in Fig.4 kann man sehr gut die Kontaktkammern 11 erkennen, welche zur Aufnahme der einzelnen federnden Anschlussklemmen 2 bzw. der Kontaktbauteile 1 geeignet sind.In the bottom view of the socket housing part 12 in FIG. 4, the contact chambers 11 can be recognized very well, which are suitable for receiving the individual resilient connection terminals 2 or the contact components 1.
Die Kontaktbauteile 1 mit den jeweiligen Anschlussklemmen 2 werden nun in vorgespanntem Zustand in die Kontaktkammern 11 (Fig.4) des Dosengehäuseteils 12 der Steckdose eingebracht, wobei die jeweiligen Kontaktbaugruppen, bestehend aus Anschlussklemmen 2 und Kontaktbauteilen 1 mittels Hinterrastungen 17 sowie Stützwänden 18 so in ihrer Lage fixiert werden, dass die Anschlussfenster 7 im vorgespannten Zustand der Anschlussklemme 2 direkt hinter den Öffnung 16 positioniert sind. Die Bedienelemente 15 sind einstückig mit dem Dosengehäuseteil 12 gefertigt und an den Seiten und stirnseitig spritztechnisch freigeformt. Die Ausrichtung der Anschlussfenster 7 direkt hinter den Leitungseinführungsöffnungen 16 ermöglichen das Einschieben der elektrischen Anschlussleitungen in das innere der elektrischen Steckvorrichtung.The contact components 1 with the respective connection terminals 2 are now introduced into the contact chambers 11 (FIG. 4) of the socket housing part 12 of the socket in the prestressed state, the respective contact assemblies consisting of connection terminals 2 and contact components 1 by means of rear catches 17 and supporting walls 18 in their way Position fixed that the connection window 7 are positioned directly behind the opening 16 in the pretensioned state of the terminal 2. The control elements 15 are made in one piece with the can housing part 12 and are injection molded on the sides and front. The alignment of the connection window 7 directly behind the line entry openings 16 enables the electrical connection lines to be inserted into the interior of the electrical plug device.
Um die Vorspannung aufzulösen und die elektrischen Anschlussleitungen gegen den Anschlussbereich 4 des Kontaktbauteils 1 zu klemmen, werden nun die Bedienelemente 15 niedergedrückt . Dadurch setzen diese im Inneren der Kontaktkammer 11 auf die Druckfläche 13 der jeweiligen federartigen Zunge des Kontakbauteils 1 auf und bewegen diese nach unten und somit die Rasthaken 10 aus den Öffnungen 8 der Klemmschenkel 2a, 2b heraus, wodurch sich die Anschlussfenster 7 mittels eigener Federkraft auf die Adern der elektrischen Anschlussleitungen legen und diese dauerhaft unter Federkraft auf den Anschlussbereich 4 des Kontaktbauteils 1 drückt. Somit ist einer einzelnen Peröon leicht möglich, die elektrischen Anschlussleitungen ohne zusätzliches Werkzeughilfsmaterial mit den federnden Anschlussklemmen dauerhaft und elektrisch leitend zu verbinden.In order to dissolve the bias and to clamp the electrical connection lines against the connection area 4 of the contact component 1, the operating elements 15 depressed. As a result, they are placed inside the contact chamber 11 on the pressure surface 13 of the respective spring-like tongue of the contact component 1 and move it downward and thus the latching hooks 10 out of the openings 8 of the clamping legs 2a, 2b, as a result of which the connection window 7 opens up by means of its own spring force lay the wires of the electrical connection lines and press them permanently under spring force onto the connection area 4 of the contact component 1. This makes it easy for a single person to permanently connect the electrical connection lines to the resilient connection terminals without additional tooling material and in an electrically conductive manner.
Um die ursprünglich vorhandene Vorspannung wieder herzustellen und die Öffnungen 8 wieder in die Rasthaken 10 einzurasten ist es lediglich erforderlich, mit einem stiftförmigen Gegenstand über die Öffnungen 16a auf die jeweiligen federnd abstehenden Klemmteile 2a, 2b zu drücken und so diese in Richtung Rasthaken 10 zu schieben, bis eine Einrastung erfolgt. Die einzelnen Adern der elektrischen Anschlussleitungen können dann problemlos entnommen werden, da sie von den jeweiligen Anschlussfenstern 7 freigegeben wurden.In order to restore the original pre-tension and to snap the openings 8 back into the locking hooks 10, it is only necessary to press the respective spring-projecting clamping parts 2a, 2b with a pin-shaped object through the openings 16a and thus to push them towards the locking hooks 10 until it snaps into place. The individual wires of the electrical connection lines can then be removed without any problems since they have been released by the respective connection windows 7.
Fig.8 und 9 zeigen ebenfalls eine erfindungsgemäße Steckvorrichtung allerdings in Form eines Steckers. Die Funktionsweise ist die gleich wie bisher beschrieben. Die einzelnen Elemente wurden daher auch mit identischen Bezugsziffern versehen. Im Unterschied zur Steckdose aus den vorhergehenden Figuren, weist der Stecker jedoch Steckerstifte 20 auf, die zum Einführen in eine entsprechende Steckdose vorgesehen sind. Im vorliegenden Beispiel ist vorgesehen den Gehäuseteil 12a mittels Befestigungsmittel 21 am Gehäuseteil 12b zu befestigen. Auf diese Art und Weise können die Anschlussklemmen in den vorgesehen Zwischenräumen zwischen diesen beiden Gehäuseteilen befestigt werden. 8 and 9 also show a plug device according to the invention, however in the form of a plug. The mode of operation is the same as previously described. The individual elements have therefore been given identical reference numbers. In contrast to the socket from the previous figures, however, the plug has plug pins 20 which are provided for insertion into a corresponding socket. In the present example it is provided to fasten the housing part 12a to the housing part 12b by means of fastening means 21. In this way, the connection terminals can be fastened in the spaces provided between these two housing parts.
