Description

Die Erfindung betrifft eine elektrische Anschlussklemme mit einem Klemmengehäuse aus einem elektrisch isolierenden Material, wobei das Klemmengehäuse mindestens eine einseitige Öffnung zum Einführen eines oder mehrerer Leiterenden aufweist, einem mindestens zweiteiligen, ein bewegliches und ein festes Teil umfassenden Klemmenkörper, welcher eine Kontaktfläche zur Kontaktierung des jeweiligen Leiterendes besitzt, wobei das jeweilige Leiterende kraftschlüssig im Klemmenkörper gehalten ist, sowie mit einem Untersteckschutz, welcher den in Abhängigkeit von der jeweiligen Position des Klemmenkörpers im Klemmengehäuse verbleibenden Freiraum der Öffnung des Klemmengehäuses verschließt, gemäß Oberbegriff des Anspruchs 1.The invention relates to an electrical terminal with a terminal housing made of an electrically insulating material, wherein the terminal housing has at least one one-sided opening for insertion of one or more conductor ends, an at least two-part, a movable and a fixed part comprehensive terminal body, which has a contact surface for contacting the respective Conductor end has, with the respective conductor end is held non-positively in the clamp body, as well as with a Untersteckschutz, which closes depending on the respective position of the clamp body in the terminal housing remaining space of the opening of the terminal housing, according to the preamble of claim 1.

Dokument FR 2 738 676 A1 offenbart eine elektrische Anschlussklemme gemäß Oberbegriff des Anspruchs 1. Aus der EP 1 580 845 B1 ist eine Endgeräteeinrichtung für elektrische Vorrichtungen bekannt. Eine metallische Fassung stellt diesbezüglich einen Klemmenkörper dar, der über eine Schraubplatte in der Lage ist, elektrische Leiter einerseits als auch Anschlüsse eines Endgeräts aufzunehmen. Insofern besitzt der dortige in einem Gehäuse befindliche Klemmenkörper zwei Öffnungsseiten, die sich gegenüberliegen und die jeweils entsprechende Anschlussenden in elektrischer Hinsicht aufnehmen und fixieren können.document FR 2 738 676 A1 discloses an electrical terminal according to the preamble of claim 1. From the EP 1 580 845 B1 a terminal device for electrical devices is known. A metallic version is in this respect a terminal body, which is via a screw plate able to receive electrical conductors on the one hand and terminals of a terminal. In this respect, the local terminal body located in a housing has two opening sides which lie opposite one another and can receive and fix the respectively corresponding terminal ends in electrical terms.

Das Klemmengehäuse weist diesbezügliche Öffnungen zur Aufnahme entsprechender Verbindungsenden elektrischer Drähte sowie zur Einführung einer Endgeräteplatte auf. Eine elastische Stütze ist einstückig von der Rückseitenwand des Klemmengehäuses so ausgebildet, dass von der Unterseite her eine der Öffnungen zur Aufnahme von Leiterenden verschließbar ist. Insofern stellt die dortige Lehre auch einen Untersteckschutz dar, der verhindert, dass eine unerwünschte Kontaktierung erfolgt, wobei es jedoch primär darum geht, ein Durchstecken eines der beiden Leiterenden zu verhindern. Demnach hat der dortige Untersteckschutz auch die Wirkung eines Anschlags bei Klemmenkörpern, die beidseitig für elektrische Leiter zugänglich sind.The terminal housing has respective openings for receiving corresponding connection ends of electrical wires and for introducing a terminal plate. An elastic support is integrally formed from the rear side wall of the terminal housing so that from the bottom of one of the openings for receiving conductor ends is closed. In this respect, the teaching there is also an undercut protection, which prevents unwanted contacting takes place, but it is primarily about preventing insertion of one of the two conductor ends. Accordingly, the local Untersteckschutz also has the effect of a stop in terminal bodies, which are accessible on both sides for electrical conductors.

Die gattungsbildende DE 10 2012 012 361 A1 zeigt eine elektrische Anschlussklemme mit einem Klemmengehäuse aus Isolierstoff, wobei das Klemmengehäuse eine Öffnung zur Einführung eines elektrischen Leiters aufweist. Im Klemmengehäuse befindet sich ein Leiteranschlusskörper mit einer Kontaktfläche zur Kontaktierung des in die Anschlussklemme eingesteckten jeweiligen elektrischen Leiters. Darüber hinaus ist ein Untersteckschutz vorhanden, der in einem durch das Klemmengehäuse und eine Begrenzungsfläche des Leiteranschlusskörpers begrenzten Zwischenraum angeordnet ist, wobei die Begrenzungsfläche auf der der Kontaktfläche abgewandten Seite des Leiteranschlusskörpers befindlich ist.The generic DE 10 2012 012 361 A1 shows an electrical terminal with a terminal housing made of insulating material, wherein the terminal housing has an opening for insertion of an electrical conductor. The terminal housing contains a conductor connection body with a contact surface for contacting the respective electrical conductor inserted in the connection terminal. In addition, a Untersteckschutz is present, which is arranged in a limited by the terminal housing and a boundary surface of the conductor connecting body gap, wherein the boundary surface is located on the side facing away from the contact surface of the conductor connecting body.

Der Untersteckschutz ist derart aus dem Klemmengehäuse geformt, dass er in jeder Betriebslage des Leiteranschlusskörpers lediglich mit einem freien Ende an der vorerwähnten Begrenzungsfläche anliegt.The Untersteckschutz is formed from the terminal housing so that it rests in each operating position of the conductor connection body only with a free end of the aforementioned boundary surface.

Gemäß der DE 10 2012 012 361 A1 wird als zweckmäßig herausgestellt, den Untersteckschutz an der die Öffnung aufweisenden Seite des Klemmengehäuses auszubilden, wodurch es möglich sein soll, den Untersteckschutz als Teil der die Öffnung bildenden Begrenzungswand des Klemmengehäuses auszuführen. Bereits aus dieser Maßnahme ergibt sich, dass der Untersteckschutz nicht nachgerüstet bzw. wahlweise vorgesehen werden kann, da dieser Bestandteil des Klemmengehäuses ist, welches regelmäßig als KunststoffSpritzteil gefertigt wird.According to the DE 10 2012 012 361 A1 is found to be useful to form the Untersteckschutz to the opening having the side of the terminal housing, whereby it should be possible to perform the Untersteckschutz as part of the opening forming boundary wall of the terminal housing. Already from this measure it follows that the Untersteckschutz can not be retrofitted or optionally provided, as this is part of the terminal housing, which is regularly manufactured as a plastic injection molding.

Konkret wird der vorbekannte Untersteckschutz als eine für den Leiterdraht sich darstellende Rampe in Form einer elastischen Zunge ausgeführt, wobei das freie Zungenende in Anschlag mit einer Unterseite des beweglichen Leiteranschlusskörpers kommt. Je nach Position des Leiteranschlusskörpers im Klemmengehäuse verändert sich die Lage der elastischen Zunge.Specifically, the prior art Untersteckschutz is designed as a conductor wire for performing ramp in the form of an elastic tongue, the free end of the tongue comes into abutment with a bottom of the movable conductor connection body. Depending on the position of the conductor connection body in the terminal housing, the position of the elastic tongue changes.

Bei einer weiteren Ausführungsform soll der Untersteckschutz als eine Parallelschwinge ausgebildet werden, wobei diese zumindest zwei zueinander parallel verlaufende Stege aufweist, an deren freien Enden quer dazu eine Kontaktzunge ausgebildet ist. Die Kontaktzunge soll sich relativ zu dem Leitungskörper derart ausrichten können, dass sich selbige im Wesentlichen analog zum Leiteranschlusskörper bewegt.In another embodiment, the Untersteckschutz to be formed as a parallel rocker, which has at least two mutually parallel webs, at the free ends transverse to a contact tongue is formed. The contact tongue should be able to align relative to the line body in such a way that it moves essentially analogously to the line connection body.

Auch bei dieser Ausführungsform ist letztendlich der Untersteckschutz aus dem Klemmengehäuse ausgebildet und damit integraler Bestandteil desselben, mit den vorstehend erwähnten Nachteilen.Also in this embodiment, the Untersteckschutz is ultimately formed from the terminal housing and thus an integral part of the same, with the disadvantages mentioned above.

Aus dem Vorgenannten ist es Aufgabe der Erfindung, eine weiterentwickelte elektrische Anschlussklemme mit Untersteckschutz anzugeben, wobei der eigentliche Untersteckschutz sehr kostengünstig realisiert werden soll und die Möglichkeit besteht, den Untersteckschutz wahlweise einzusetzen oder aber auch nachzurüsten.From the foregoing, it is an object of the invention to provide a further developed electrical terminal with Untersteckschutz, the actual Untersteckschutz to be realized very inexpensively and the possibility exists to use the Untersteckschutz either or alternatively retrofit.

Die Lösung der Aufgabe der Erfindung erfolgt mit der Lehre gemäß der Merkmalskombination nach Anspruch 1, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen darstellen.The object of the invention is achieved with the teaching according to the feature combination according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.

Es wird demnach von einer elektrischen Anschlussklemme mit einem Klemmengehäuse aus einem elektrisch isolierenden Material, beispielsweise Kunststoff, ausgegangen, wobei das Klemmengehäuse mindestens eine einseitige Öffnung zum Einführen eines oder mehreren Enden elektrischer Leiter aufweist.It is therefore assumed that an electrical terminal with a terminal housing made of an electrically insulating material, such as plastic, wherein the terminal housing has at least one one-sided opening for insertion of one or more ends of electrical conductors.

Darüber hinaus ist ein mindestens oder bevorzugt zweiteiliger Klemmenkörper vorhanden, wobei der Klemmenkörper ein bewegliches und ein festes Teil umfasst. Derartige Klemmenkörper sind aus dem Stand der Technik bekannt, so dass sich eine nähere Darstellung und Erläuterung an dieser Stelle erübrigt.In addition, an at least or preferably two-piece clamp body is present, wherein the clamp body comprises a movable and a fixed part. Such terminal body are known from the prior art, so that a closer representation and explanation is unnecessary at this point.

Der entsprechende Klemmenkörper besitzt eine Kontaktfläche zur Kontaktierung des jeweiligen Leiterendes, wobei das jeweilige Leiterende kraftschlüssig im Klemmenkörper gehalten ist. Dieser Kraftschluss wird bevorzugt durch eine Schraub-Klemmverbindung oder eine Rast-Kiemmverbindung erzeugt.The corresponding terminal body has a contact surface for contacting the respective conductor end, wherein the respective conductor end is held non-positively in the clamp body. This adhesion is preferably generated by a screw-clamp connection or a snap-Kiemmverbindung.

Darüber hinaus ist ein Untersteckschutz vorhanden, welcher den in Abhängigkeit von der jeweiligen Position des Klemmenkörpers im Klemmengehäuse verbleibenden Freiraum der Öffnung des Klemmengehäuses verschließt.In addition, a Untersteckschutz is present, which closes the remaining depending on the position of the terminal body in the terminal housing clearance of the opening of the terminal housing.

Erfindungsgemäß ist der Untersteckschutz aus einem zwei Flächenstücke einschließenden Gelenkteil bestehend, wobei ein erstes Flächenstück mit einer freien Unterseite des beweglichen Teiles des Klemmenkörpers kraft-, form-und/oder stoffschlüssig verbunden ist.
Ein zweites Flächenstück hingegen ist verschiebebeweglich im Klemmengehäuse gelagert.
Diese Verschiebebeweglichkeit ermöglicht es, dass bei einer Veränderung der Position des Klemmenkörpers das zweite Flächenstück dieser Bewegung folgt, so dass das gewünschte Verschließen des Öffnungsfreiraums gegeben ist und ein nicht korrektes Einstecken oder Einbringen von Leiterenden wirksam verhindert wird.
According to the invention the Untersteckschutz consists of a two surface pieces enclosing hinge part, wherein a first surface piece with a free underside of the movable part of the clamp body is positively, positively and / or materially connected.
A second surface piece, however, is displaceably mounted in the terminal housing.
This translational mobility enables the second sheet to follow this movement as the position of the clamp body changes, thus providing the desired closure of the opening clearance and effectively preventing improper insertion or insertion of conductor ends.

Das zweite Flächenstück weist an seinen freien, seitlichen Enden Lagerzapfen auf, welche in jeweiligen Nuten, insbesondere Längsnuten im Klemmengehäuse geführt werden.
Diese Nuten verlaufen im Wesentlichen senkrecht zur Bewegungsrichtung des beweglichen Teils des Klemmenkörpers im Klemmengehäuse.
Die vorerwähnten Nuten können grundsätzlich bei entsprechenden Klemmengehäusen im Rahmen üblicher Spritzverfahren erzeugt werden, wobei dann die Freiheit besteht, montageseitig klassische Klemmen bzw. Klemmenkörper ohne Untersteckschutz oder derartige mit dem erfindungsgemäßen Untersteckschutz einzusetzen bzw. zu verwenden.
Bei einer ersten Ausführungsform sind das erste und das zweite Flächenstück des Untersteckschutzes über ein Drehgelenk mit entsprechender Gelenkachse verbunden.
Bei einer weiteren Ausführungsform sind das erste und das zweite Flächenstück des Untersteckschutzes über ein Filmscharniergelenk verbunden.
Bei dieser Ausführungsform besteht insbesondere die kostengünstige Möglichkeit, das erste und zweite Flächenstück sowie das Filmscharnier als einteiliges Spritzteil auszuführen.
The second surface piece has at its free, lateral ends bearing journals, which are guided in respective grooves, in particular longitudinal grooves in the terminal housing.
These grooves are substantially perpendicular to the direction of movement of the movable part of the clamp body in the terminal housing.
The above-mentioned grooves can in principle be produced in the case of corresponding terminal housings within the scope of conventional spraying methods, in which case the freedom exists to use or to use conventional terminals or clamp bodies without undercut protection or such with the inventive undercut protection.
In a first embodiment, the first and the second surface piece of the Untersteckschutzes are connected via a rotary joint with a corresponding hinge axis.
In a further embodiment, the first and the second surface piece of the Untersteckschutzes are connected via a film hinge joint.
In this embodiment, in particular, there is the cost-effective way to perform the first and second surface piece and the film hinge as a one-piece molded part.

Bevorzugt ist das erste Flächenstück starr und das zweite Flächenstück flexibel ausbildbar.Preferably, the first surface piece is rigid and the second surface piece can be flexibly formed.

Bei einer Weiterbildung der Erfindung ist am zur Öffnung weisenden Ende des ersten Flächenstücks eine Einführschräge für das jeweilige Leiterende ausgebildet, so dass sich eine Montageerleichterung bezüglich des Einführens der entsprechenden Leiter ergibt.In a further development of the invention, an insertion bevel for the respective conductor end is formed at the opening facing the end of the first surface piece, so that there is a mounting relief with respect to the insertion of the corresponding conductor.

Weiterhin besteht die Möglichkeit, dass das erste Flächenstück am zur Öffnung weisenden Ende die diesbezügliche Vorderkante des beweglichen Teils des Klemmenkörpers umschließt und an dieser anliegt, so dass insgesamt der Untersteckschutz sicher am Klemmenkörper fixiert ist.Furthermore, there is the possibility that the first surface piece at the end facing the opening encloses the relevant front edge of the movable part of the clamp body and bears against this, so that overall the shunt protector is securely fixed to the clamp body.

Die erfindungsgemäße Ausbildung des Untersteckschutzes aus einem zwei Flächenstücke einschließenden Gelenkteil, die sich bei vollständiger Öffnung des Klemmenkörpers aneinander anlegen und quasi zusammengeklappt sind, schränkt die Öffnungsbewegung des Klemmenkörpers, wie sie insbesondere beim Einführen von Leitern größerer Querschnitte erforderlich ist, nicht ein.The inventive construction of the Untersteckschutzes of a two-piece enclosing joint part, which create each other with complete opening of the clamp body and are virtually collapsed, does not limit the opening movement of the clamp body, as required in particular for the introduction of conductors of larger cross-sections.

Über die Ausführung eines Drehlagers zwischen den zwei Flächenstücken und eines quasi Schiebelagers im Bereich der Nuten des Klemmengehäuses ergibt sich bei geschlossenem Klemmenkörper bzw. bei dessen Schließvorgang keine Behinderung. Insbesondere das zweite Flächenstück kann mit einer Signalfarbe versehen sein, um mit einem Blick in Öffnungsrichtung der jeweiligen Klemmengehäuse die Position des Klemmenkörpers zu erkennen, um dann bei bevorstehender Montage den beweglichen Teil des Klemmenkörpers so zu verstellen, dass ein ungehindertes Einführen der betreffenden Leiterenden möglich wird.About the execution of a pivot bearing between the two surface pieces and a quasi sliding bearing in the region of the grooves of the terminal housing results in closed terminal body or during its closing operation no obstruction. In particular, the second patch can be provided with a signal color to detect the position of the terminal body with a view in the opening direction of the respective terminal housing, then to adjust the forthcoming mounting the movable part of the clamp body so that unimpeded insertion of the relevant conductor ends is possible ,

Weiterhin ist ein mindestens zweiteiliger Klemmenkörper vorhanden.Furthermore, an at least two-part clamp body is present.

Der Klemmenkörper besteht bei den gezeigten Ausführungsbeispielen aus einem beweglichen Klemmenkörperteil 3 und einem festen Klemmenkörperteil 4.In the embodiments shown, the clamp body consists of a movable clamp body part 3 and a fixed clamp body part 4.

Mit Hilfe einer Klemmschraube 5, deren Gewinde mit einem Innengewinde im beweglichen Teil 3 des Klemmenkörpers korrespondiert, kann der bewegliche Teil von einer offenen Position in eine geschlossene Position, d.h. Klemmposition verbracht werden.By means of a clamping screw 5, the threads of which correspond to an internal thread in the movable part 3 of the clamp body, the movable part can be moved from an open position to a closed position, i.e. to a fixed position. Clamping be spent.

Im Inneren des beweglichen Teiles und/oder am unteren Ende des festen Teiles des Klemmenkörpers ist eine Kontaktfläche zur Kontaktierung des jeweiligen Leiterendes vorhanden.Inside the movable part and / or at the lower end of the fixed part of the clamp body there is a contact surface for contacting the respective conductor end.

Das jeweilige Leiterende kann demnach kraftschlüssig im Klemmenkörper gehalten werden.The respective conductor end can therefore be held non-positively in the clamp body.

Der bei den Ausführungsbeispielen vorgesehene Untersteckschutz verschließt den in Abhängigkeit von der jeweiligen Position des Klemmenkörpers, insbesondere des beweglichen Teiles 3, den im Klemmengehäuse verbleibenden Freiraum der Öffnung 2.The undercut protection provided in the exemplary embodiments closes the free space of the opening 2 remaining in the terminal housing, depending on the respective position of the terminal body, in particular of the movable part 3.

Der Untersteckschutz besteht erfindungsgemäß aus zwei Flächenstücken und einem entsprechenden Gelenkteil.The Untersteckschutz according to the invention consists of two surface pieces and a corresponding hinge part.

Ein erstes Flächenstück 6 ist mit einer freien Unterseite des beweglichen Teiles 3 des Klemmenkörpers kraft-, form- und/oder stoffschlüssig verbunden.A first surface piece 6 is positively, positively and / or materially connected to a free underside of the movable part 3 of the clamp body.

Ein zweites Flächenstück 7 ist hingegen verschiebebeweglich im Klemmengehäuse 1 gelagert.A second surface piece 7, however, is displaceably mounted in the terminal housing 1.

Diesbezüglich weist das zweite Flächenstück 7 an seinen freien Enden seitliche Lagerzapfen 8 auf, welche in entsprechenden komplementären Nuten 9 im Klemmengehäuse 1 geführt werden.In this regard, the second surface portion 7 at its free ends lateral bearing pin 8, which are guided in corresponding complementary grooves 9 in the terminal housing 1.

Die Nuten 9 verlaufen im Wesentlichen senkrecht zur Bewegungsrichtung des beweglichen Teiles 3 des Klemmenkörpers im Klemmengehäuse 1.The grooves 9 extend substantially perpendicular to the direction of movement of the movable part 3 of the clamp body in the terminal housing. 1

Wie aus den Darstellungen nach den Fig. 1a bis 1d und 2a und 2b ersichtlich, ist bei der ersten Ausführungsform das erste und das zweite Flächenstück 6; 7 über ein Drehgelenk 10 verbunden. Das Drehgelenk 10 kann aus entsprechenden Achsstümpfen bestehen, die am zweiten Flächenstück 7 angeformt sind und welche in diesbezüglich komplementäre Bohrungen im ersten Flächenstück 6 eingreifen, wobei hier natürlich auch eine kinematische Umkehr der Ausführung Achse / Buchse denkbar ist.As from the representations after the Fig. 1a to 1d and 2a and 2b it can be seen, in the first embodiment, the first and the second surface piece 6; 7 connected via a rotary joint 10. The rotary joint 10 may consist of corresponding Achsstümpfen, which are integrally formed on the second surface piece 7 and which engage in this respect complementary bores in the first surface piece 6, which of course also a kinematic reversal of the execution axis / socket is conceivable.

Die Abfolge der Darstellungen in den Fig. 1a bis 1d zeigt auf, wie bei einer Bewegung des beweglichen Teiles 3 des Klemmenkörpers von einer offenen in eine geschlossene Position der Untersteckschutz seine Wirkung entfaltet, indem das zweite Flächenstück 7 unter Wirkung von Dreh- und Schiebegelenk den Raum unterhalb des beweglichen Teiles 3 des Klemmenkörpers verschließt.The sequence of representations in the Fig. 1a to 1d shows how in a movement of the movable part 3 of the clamp body from an open to a closed position of the shunt protects its effect by the second surface piece 7 closes under the action of rotating and sliding joint the space below the movable part 3 of the clamp body.

Durch die Kombination Drehgelenk und Schiebelager ist es auch nur gewaltsam oder zerstörend möglich, dennoch einen Gegenstand einzuführen.The combination swivel and sliding bearing, it is only possible by force or destructive, yet introduce an object.

Auch die Fig. 2a und 2b zeigen diesbezüglich zwei relevante Zustände einmal mit geschlossenem (Fig. 2a) und offenem (Fig. 2b) Klemmenkörper.Also the Fig. 2a and 2b show in this regard two relevant states once with closed ( Fig. 2a ) and open ( Fig. 2b ) Terminal body.

Bei einer weiteren Ausführungsform der Erfindung besteht die Möglichkeit, das erste und das zweite Flächenstück 6; 7 über ein Filmscharnier 11 zu verbinden, wobei das erste und das zweite Flächenstück 6; 7 nebst Filmscharnier 11 auch als einteiliges Spritzteil fertigbar sind.In a further embodiment of the invention, it is possible, the first and the second surface piece 6; 7 to connect via a film hinge 11, wherein the first and the second surface piece 6; 7 in addition to film hinge 11 can be manufactured as a one-piece molded part.

Bei einer figürlich nicht gezeigten Ausgestaltung besteht die Möglichkeit, das erste Flächenstück 6 als ein starres Teil und das zweite Flächenstück 7 als ein grundsätzlich flexibles Teil auszubilden, um quasi analog eines flexiblen Verschlusses im Sinne eines Vorhangs den Öffnungsbereich unterhalb des beweglichen Teiles 3 des Klemmenkörpers zu verschließen.In a figuratively not shown embodiment, it is possible to form the first surface piece 6 as a rigid part and the second surface piece 7 as a fundamentally flexible part to quasi analogous to a flexible closure in the sense of a curtain the opening area below the movable part 3 of the clamp body close.

Um das Einführen der jeweiligen elektrischen Leiterenden durch den Untersteckschutz nicht zu beeinträchtigen, vielmehr im Gegenteil dieses Einführen zu erleichtern, ist am Vorderende des ersten Flächenstücks 6 eine Einführschräge 12 ausgebildet bzw. angeformt.In order not to interfere with the insertion of the respective electrical conductor ends by the Untersteckschutz, but on the contrary to facilitate this insertion, an insertion bevel 12 is formed or formed at the front end of the first surface portion 6.

Im Zusammenhang mit der Ausgestaltung der Einführschräge 12 ist es von Vorteil, wenn das erste Flächenstück 6 am zur Öffnung weisenden Ende die diesbezügliche Vorderkante des beweglichen Teiles 3 des Klemmenkörpers umschließt bzw. dort bündig zur Anlage kommt.In connection with the design of the insertion bevel 12, it is advantageous if the first surface piece 6 surrounds the relevant front edge of the movable part 3 of the clamp body at the end pointing to the opening or comes to bear flush there.
