Definitions
- the invention relates to a protective conductor terminal with an insulating housing, a busbar arranged thereon and a fastening and contact foot connected to the busbar, which has hook and spring means for interacting with the mounting rail leg for mechanical and electrical connection to a mounting rail which acts as a protective busbar for further mechanical connection to the mounting rail on the insulating material housing, at least on one side a locking spring strut is provided which engages under the mounting rail leg.
- the hook and spring means of the metallic fastening and contact foot of such protective conductor terminals cannot be designed so stiff that an untimely Snapping from the mounting rail with a particularly strong conductor path could be excluded. At least on one side, the snap-on must be possible without excessive effort.
- a protective conductor terminal of the generic type in which, in addition to a hook element under the support rail leg of the metallic fastening and contact foot of the protective conductor terminal on its insulating material housing, a catch spring strut is also formed underneath the support rail leg, on the outside of the The hook element of the fastening and contact foot rests in such a way that the spring forces of the metal foot and the plastic foot add up in order to increase the resistance to untimely snapping. Blocking against scanning in the sense of making it impossible is not associated with this.
- a mounting foot for attaching electrical / electronic components to a mounting rail is known, in which an additional locking strut is pivotally formed on the plastic mounting foot via a film hinge such that this locking strut in a blocking position behind that on the Carrier rail detent spring can be pivoted at this mounting foot.
- the locking strut formed over the film hinge represents an additional component, whereby there is the need to pivot the locking strut into the blocking position in a separate additional operation in order to ensure the blocking.
- the present invention is therefore based on the object of providing a protective conductor terminal of the generic type which does not snap off the mounting rail prematurely even under high mechanical loads, in particular with a heavy conductor.
- the solution according to the invention results from the characterizing part of patent claim 1.
- the detent spring strut of the insulating material housing is thus given a double function. It is not only used for the mechanical connection of the protective conductor terminal to the corresponding mounting rail leg, but also for blocking the hook of the metal mounting and contact foot on the mounting rail, so that an untimely detachment is not possible even with a strong conductor.
- the abutment is designed as a correspondingly shaped angle piece. The two undercut angle pieces block each other very quickly at the start of a scanning movement of the hook of the fastening and contact foot as a result of the conductor path.
- the untimely scanning movement as a result of the conductor path initially causes the hook of the fastening and contact foot to move outward. This movement is already blocked by the undercut elbows.
- the blockage is mutual, so that due to this blockage also the detent strut Isolierstoffgeophuses can only move in the sense of an untimely scanning due to the conductor.
- an active surface is provided on the latching spring strut of the insulating material housing on the side of the engagement zone with the mounting rail leg that acts on the hook of the fastening and contact foot.
- the active surface on the locking spring strut bumps into the inside of the hook of the fastening and contact foot, so that the locking spring strut over the active surface takes the hook to the outside and not only the catch spring strut itself, but also the hook of the fastening and contact foot are released from the mounting rail leg.
- the protective conductor terminal has an insulating housing 1, of which only the foot area is shown for reasons of simplification.
- a busbar 2 (see FIG. 2) which is firmly connected to a metallic fastening and contact foot 3, which in turn is used for the mechanical and electrical connection of a mounting rail 4 acting as a protective conductor busbar with various hook and spring means is provided, which are formed in the illustrated embodiment by more or less elastic support legs 5, 6, which are supported on the mounting rail legs and by the mounting rail legs engaging under, more or less elastic hooks 7, 8.
- at least one of the support legs can be formed by a separate spring to be inserted.
- Conductor connections are located on the busbar 2.
- the conductors are inserted, for example, from above into the insulating housing 1, so that in this case it can be assumed that the conductor path is directed upwards and, with the appropriate thickness, could cause the protective conductor terminal to snap off the mounting rail 4.
- the foot region of the insulating housing 1 is designed as a detent spring strut 9, which with a Hook piece 10 engages under the corresponding leg of the mounting rail 4.
- This detent spring strut 9 is now also assigned a further function, in such a way that an abutment 11 is provided on it, with which the adjacent hook 7 of the fastening and contact foot 3 is blocked in its detent position against a detent movement by the mounting rail leg as a result of the conductor track .
- an embodiment is provided according to which an angled portion 12 with an undercut is formed on the hook 7 of the fastening and contact foot 3 on the outside facing away from its zone of engagement with the mounting rail leg.
- the abutment 11 on the detent spring strut 9 is a correspondingly shaped angle piece which protrudes into the bend 12 of the hook 7.
- an active surface 14 is now provided on the catch spring 9 on the hook 7 of the fastening and contact foot 3 on its side corresponding to the engagement zone with the mounting rail leg.
- a pocket 15 overlapping the bend 12 of the hook 7 is formed on the detent spring strut 9, the inner surface of which forms the active surface 14.
- the active surface 14 thus immediately meets the opposite inner surface at the angled end of the hook 7, so that the detent spring 9 then takes the hook 7 with it in the unlocking movement and both come free from the mounting rail leg.

Description
Die Erfindung betrifft eine Schutzleiterklemme mit einem Isolierstoffgehäuse, einer daran angeordneten Stromschiene und einem mit der Stromschiene verbundenen Befestigungs- und Kontaktfuß, der zur mechanischen und elektrischen Verbindung mit einer als Schutzleiter-Sammelschiene wirkenden Tragschiene Haken- und Federmittel zum Zusammenwirken mit dem Tragschienenschenkel aufweist, wobei zur weiteren mechanischen Verbindung mit der Tragschiene an dem Isolierstoffgehäuse zumindest auf einer Seite ein den Tragschienenschenkel untergreifendes Rastfederbein vorgesehen ist.The invention relates to a protective conductor terminal with an insulating housing, a busbar arranged thereon and a fastening and contact foot connected to the busbar, which has hook and spring means for interacting with the mounting rail leg for mechanical and electrical connection to a mounting rail which acts as a protective busbar for further mechanical connection to the mounting rail on the insulating material housing, at least on one side a locking spring strut is provided which engages under the mounting rail leg.
Im Hinblick auf die sonst möglicherweise zu hoch werdenden Aufrastkräfte beim Aufrasten derartiger Schutzleiterklemmen auf die Tragschienen und im Hinblick auf den Beibehalt einer möglichst einfachen Konstruktion können die Haken- und Federmittel des metallischen Befestigungs- und Kontaktfußes derartiger Schutzleiterklemmen nicht so steif ausgelegt werden, daß ein unzeitiges Abrasten von der Tragschiene bei besonders starkem Leiterzug ausgeschlossen werden könnte. Zumindest an einer Seite muß sich die Aufrastung ohne übermäßigen Kraftaufwand ermöglichen lassen. Um einer unzeitigen Abrastung infolge Leiterzug entgegenzuwirken, ist es bereits bei einer derartigen Schutzleiterklemme bekannt, auf der einen Seite zusätzlich zu dem Haken des Befestigungs- und Kontaktfußes auch am Isolierstoffgehäuse ein den Tragschienenschenkel untergreifendes Rastfederbein vorzusehen, das einer unzeitigen Abrastung entgegenwirken soll (Katalog der Firma WAGO Kontakttechnik GmbH, HK 1-3/2.88, 1.20 Schutzleiterklemmen). Schon aufgrund der Elastizitätseigenschaften des Isolierstoffmateriales kann aber auch hier bei sehr starkem Leiterzug, insbesondere bei nach oben gerichtetem Leiterzug, nicht mit der erforderlichen Sicherheit ausgeschlossen werden, daß es zu einem unzeitigen Abrasten auch des Rastfederbeines des Isolierstoffgehäuses und damit der Schutzleiterklemme insgesamt von der Tragschiene kommt.In view of the otherwise possibly too high snap-on forces when such protective conductor terminals are snapped onto the mounting rails and in view of the simplest possible construction, the hook and spring means of the metallic fastening and contact foot of such protective conductor terminals cannot be designed so stiff that an untimely Snapping from the mounting rail with a particularly strong conductor path could be excluded. At least on one side, the snap-on must be possible without excessive effort. In order to counteract an untimely detent as a result of the conductor run, it is already known with such a protective conductor terminal, on the one hand, in addition to the hook of the fastening and contact foot, to also provide on the insulating housing a detent spring which engages under the mounting rail leg and which is intended to counteract an untimely detent (catalog of the company WAGO Kontakttechnik GmbH, HK 1-3 / 2.88, 1.20 protective conductor terminals). Already because of the However, elastic properties of the insulating material cannot be excluded with the necessary certainty even with a very strong conductor path, in particular when the conductor path is directed upwards, that there is also an untimely snapping of the locking spring strut of the insulating material housing and thus of the protective conductor terminal as a whole from the mounting rail.
Aus der DE-U-92 10 064 ist eine Schutzleiterklemme der gattungsgemäßen Art bekannt, bei der zusätzlich zu einem den Tragschienenschenkel untergreifenden Hakenelement des metallischen Befestigungs- und Kontaktfußes der Schutzleiterklemme an deren Isolierstoffgehäuse ein ebenfalls den Tragschienenschenkel untergreifendes Rastfederbein angeformt ist, daß außen an dem Hakenelement des Befestigungs- und Kontaktfußes so anliegt, daß sich die Federkräfte des Metallfußes und des Kunststoffußes addieren, um den Widerstand gegen ein unzeitiges Abrasten zu erhöhen. Ein Blockieren gegen ein Abrasten im Sinne eines Unmöglichmachens ist damit nicht verbunden.From DE-U-92 10 064 a protective conductor terminal of the generic type is known, in which, in addition to a hook element under the support rail leg of the metallic fastening and contact foot of the protective conductor terminal on its insulating material housing, a catch spring strut is also formed underneath the support rail leg, on the outside of the The hook element of the fastening and contact foot rests in such a way that the spring forces of the metal foot and the plastic foot add up in order to increase the resistance to untimely snapping. Blocking against scanning in the sense of making it impossible is not associated with this.
Aus der EP-A-0 300 065 ist ein Montagefuß zum Befestigen von elektrisch/elektronischen Bauelementen auf einer Tragschiene bekannt, bei der an den Kunststoffmontagefuß eine zusätzliche Verriegelungsstrebe über ein Filmschamier derart schwenkbar angeformt ist, daß diese Verriegelungsstrebe in eine Blockierstellung hinter das auf die Tragschiene gerastete Rastfederbeim dieses Montagefußes geschwenkt werden kann. Die über das Filmschamier angeformte Verriegelungsstrebe stellt ein zusätzliches Bauteil dar, wobei das Erfordemis besteht, in einem gesonderten zusätzlichen Arbeitsgang die Verriegelungsstrebe in die Blockierstellung zu verschwenken, um die Blockierung sicherzustellen.From EP-A-0 300 065 a mounting foot for attaching electrical / electronic components to a mounting rail is known, in which an additional locking strut is pivotally formed on the plastic mounting foot via a film hinge such that this locking strut in a blocking position behind that on the Carrier rail detent spring can be pivoted at this mounting foot. The locking strut formed over the film hinge represents an additional component, whereby there is the need to pivot the locking strut into the blocking position in a separate additional operation in order to ensure the blocking.
Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Schutzleiterklemme der gattungsgemäßen Art zu schaffen, die auch bei hohen mechanischen Belastungen, insbesondere starkem Leiterzug, nicht unzeitig von der Tragschiene abrastet.The present invention is therefore based on the object of providing a protective conductor terminal of the generic type which does not snap off the mounting rail prematurely even under high mechanical loads, in particular with a heavy conductor.
Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1. Dem Rastfederbein des Isolierstoffgehäuses ist damit eine Doppelfunktion gegeben. Es dient nicht nur der mechanischen Verbindung der Schutzleiterklemme mit dem entsprechenden Tragschienenschenkel, sondern gleichzeitig auch der Blockierung des Hakens des metallischen Befestigungs- und Kontaktfußes auf der Tragschiene, so daß auch bei starkem Leiterzug ein unzeitiges Abrasten nicht möglich ist. Gemäß einer besonders bevorzugten Ausführungsform ist das Widerlager als ein entsprechend geformtes Winkelstück ausgebildet. Die beiden hinterschnittenen Winkelstücke blockieren sich sehr schnell zu Beginn einer Abrastbewegung des Hakens des Befestigungs- und Kontaktfußes infolge Leiterzug gegenseitig. Die unzeitige Abrastbewegung infolge Leiterzug bewirkt ja zunächst eine Wanderbewegung des Hakens des Befestigungs- und Kontaktfußes in Richtung nach außen. Bereits diese Bewegung wird durch die hinterschnittenen Winkelstücke blockiert. Die Blockade ist dabei eine gegenseitige, so daß sich infolge dieser Blockade auch das Rastfederbein des Isolierstoffgehäuses nur im Sinne einer unzeitigen Abrastung infolge Leiterzug bewegen kann.The solution according to the invention results from the characterizing part of patent claim 1. The detent spring strut of the insulating material housing is thus given a double function. It is not only used for the mechanical connection of the protective conductor terminal to the corresponding mounting rail leg, but also for blocking the hook of the metal mounting and contact foot on the mounting rail, so that an untimely detachment is not possible even with a strong conductor. According to a particularly preferred embodiment, the abutment is designed as a correspondingly shaped angle piece. The two undercut angle pieces block each other very quickly at the start of a scanning movement of the hook of the fastening and contact foot as a result of the conductor path. The untimely scanning movement as a result of the conductor path initially causes the hook of the fastening and contact foot to move outward. This movement is already blocked by the undercut elbows. The blockage is mutual, so that due to this blockage also the detent strut Isolierstoffgehäuses can only move in the sense of an untimely scanning due to the conductor.
Um die Schutzleiterklemme bei dieser Ausgestaltung gewollt abrasten zu können, ist gemäß einer weiteren bevorzugten Ausgestaltung an dem Rastfederbein des Isolierstoffgehäuses eine den Haken des Befestigungs- und Kontaktfußes auf seiner der Eingriffszone mit dem Tragschienenschenkel entsprechenden Seite beaufschlagende Wirkfläche vorgesehen. Vollführt man somit mit dem Rastfederbein des Isolierstoffgehäuses die nach außen, von der Tragschiene fort gerichtete Entriegelungsbewegung, wozu zweckmäßig am Rastfederbein außenseitig eine Handhabungszone vorgesehen ist, stößt die Wirkfläche am Rastfederbein auf die Innenseite des Hakens des Befestigungs- und Kontaktfußes, so daß das Rastfederbein über die Wirkfläche den Haken mit nach außen nimmt und dadurch nicht nur das Rastfederbein selbst, sondern auch der Haken des Befestigungs- und Kontaktfußes von dem Tragschienenschenkel freikommen.In order to be able to intentionally snap the protective conductor terminal in this embodiment, according to a further preferred embodiment, an active surface is provided on the latching spring strut of the insulating material housing on the side of the engagement zone with the mounting rail leg that acts on the hook of the fastening and contact foot. Thus, if the locking spring strut of the insulating material housing carries out the unlocking movement directed outward from the mounting rail, for which purpose a handling zone is expediently provided on the outside of the locking spring strut, the active surface on the locking spring strut bumps into the inside of the hook of the fastening and contact foot, so that the locking spring strut over the active surface takes the hook to the outside and not only the catch spring strut itself, but also the hook of the fastening and contact foot are released from the mounting rail leg.

Die Schutzleiterklemme besitzt ein Isolierstoffgehäuse 1, von dem aus Gründen der Vereinfachung nur der Fußbereich dargestellt ist. In dem Isolierstoffgehäuse 1 befindet sich eine Stromschiene 2 (siehe Figur 2), die fest mit einem metallischen Befestigungs- und Kontaktfuß 3 verbunden ist, der seinerseits für die mechanische und elektrische Verbindung einer als Schutzleiter-Sammelschiene wirkenden Tragschiene 4 mit diversen Haken- und Federmitteln versehen ist, die im dargestellten Ausführungsbeispiel durch mehr oder weniger elastische Stützbeine 5, 6, die sich auf den Tragschienenschenkeln abstützen und durch die Tragschienenschenkel untergreifende, mehr oder weniger elastische Haken 7, 8 gebildet sind. In Abweichung hiervon können andere Ausgestaltungen des Befestigungs- und Kontaktfußes vorgesehen sein. So kann beispielsweise mindestens eines der Stützbeine durch eine gesonderte, einzulegende Feder gebildet werden.The protective conductor terminal has an insulating housing 1, of which only the foot area is shown for reasons of simplification. In the insulating material housing 1 there is a busbar 2 (see FIG. 2) which is firmly connected to a metallic fastening and contact foot 3, which in turn is used for the mechanical and electrical connection of a
Auf der Stromschiene 2 sitzen Leiteranschlüsse (nicht dargestellt). Die Leiter werden beispielsweise von oben in das Isolierstoffgehäuse 1 eingeführt, so daß in diesem Fall von einem nach oben gerichteten Leiterzug auszugehen ist, der bei entsprechender Stärke eine unzeitige Abrastung der Schutzleiterklemme von der Tragschiene 4 bewirken könnte.Conductor connections (not shown) are located on the
Um die Sicherung gegenüber einem unzeitigen Abrasten infolge Leiterzug zu verbessern, ist zur Unterstützung der mechanischen Verrastung des Befestigungs- und Kontaktfußes 3 im dargestellten Ausführungsbeispiel auf der linken Seite, gesehen auf die Zeichnung, der Fußbereich des Isolierstoffgehäuses 1 als Rastfederbein 9 ausgebildet, das mit einem Hakenstück 10 den entsprechenden Schenkel der Tragschiene 4 untergreift. Dabei ist nun ferner diesem Rastfederbein 9 eine weitere Funktion zugeordnet, und zwar dergestalt, daß an ihm ein Widerlager 11 vorgesehen ist, mit dem der benachbarte Haken 7 des Befestigungs- und Kontaktfußes 3 in seiner Raststellung gegen eine Abrastbewegung von dem Tragschienenschenkel infolge Leiterzuges blockiert ist.In order to improve the security against an untimely snapping due to the conductor track, to support the mechanical latching of the fastening and contact foot 3 in the exemplary embodiment shown on the left, as seen in the drawing, the foot region of the insulating housing 1 is designed as a
Im dargestellten Ausführungsbeispiel ist dabei eine Ausgestaltung vorgesehen, nach der an dem Haken 7 des Befestigungs- und Kontaktfußes 3 auf der seiner Eingriffszone mit dem Tragschienenschenkel abgewandten Außenseite eine mit Hinterschnitt nach außen verlaufende Abwinkelung 12 gebildet ist. Das Widerlager 11 an dem Rastfederbein 9 ist dabei ein entsprechend geformtes Winkelstück, das in die Abwinkelung 12 des Hakens 7 vorsteht.In the exemplary embodiment shown, an embodiment is provided according to which an
Eine unzeitige Abrastbewegung infolge nach oben gerichteten Leiterzuges würde eingangs eine nach außen gerichtete Verlagerungsbewegung des Hakens 7 des Befestigungs- und Kontaktfußes 3 bewirken, mit der er quasi von dem Tragschienenschenkel abrutschen will. Schon diese nach außen gerichtete Bewegung wird durch die sich gegenseitig blockierenden hinterschnittenen Winkelstücke 11, 12 verhindert. Die gegenseitige Blockade bewirkt dabei, daß auch das Rastfederbein 9 selbst nicht von dem Tragschienenschenkel abrasten kann.An untimely scanning movement as a result of the upwardly directed conductor line would initially cause an outward displacement movement of the
Um nun gewollt die Schutzleiterklemme abrasten zu können, ist an dem Rastfederbein 9 unten außenseitig eine Handhabungszone 13 in Form einer Stecköffnung beispielsweise für einen Schraubendreher vorgesehen, mit der dem Rastfederbein 9 eine überwiegend nach außen und auch leicht nach unten gerichtete Entriegelungsbewegung erteilt werden kann. In weiterer Ausgestaltung ist nun ferner an dem Rastfederbein 9 eine den Haken 7 des Befestigungs- und Kontaktfußes 3 auf seiner der Eingriffszone mit dem Tragschienenschenkel entsprechenden Seite beaufschlagende Wirkfläche 14 vorgesehen. Im dargestellten Ausführungsbeispiel ist dafür eine die Abwinkelung 12 des Hakens 7 übergreifende Tasche 15 an dem Rastfederbein 9 ausgebildet, deren Innenfläche die Wirkfläche 14 bildet. Bei der Entriegelungsbewegung trifft somit umgehend die Wirkfläche 14 auf die gegenüberliegende Innenfläche am abgewinkelten Ende des Hakens 7, so daß daraufhin das Rastfederbein 9 den Haken 7 in der Entriegelungsbewegung mitnimmt und beide gemeinsam von dem Tragschienenschenkel freikommen.In order to be able to snap off the protective conductor clamp, a
