Description

Die vorliegende Erfindung bezieht sich auf eine elektrische Klemme, insbesondere Reihenklemme, mit einem Gehäuse und einer an dem Gehäuse gehaltenen Stromschiene gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an electrical terminal, in particular terminal block, with a housing and a busbar held on the housing according to the preamble of claim 1.

Elektrische Klemmen sind hinlänglich bekannt. Beispielsweise bietet die Fa. Phoenix Contact mit dem Reihenklemmensystem CLIPLINE complete, RT Ring-Lug Terminal eine derartige Bolzenanschlussklemme an.Electrical terminals are well known. For example, the company Phoenix Contact offers such a bolt connection terminal with the terminal block system CLIPLINE complete, RT Ring-Lug Terminal.

Die bekannte Bolzenanschlussklemme weist ein Gehäuse und eine an dem Gehäuse gehaltene Stromschiene auf. Ferner umfasst die bekannte Klemme eine Befestigungsschraube oder eine Befestigungsmutter, die in der Benutzungslage der elektrischen Klemme mit einer dazu korrespondierenden Mutter oder Schraube derart zusammenwirkt, dass ein mit der Stromschiene elektrisch zu verbindender elektrischer Leiter zwischen der Mutter oder Schraube und der Stromschiene eingeklemmt ist.The known pin terminal has a housing and a bus bar held on the housing. Further, the known terminal comprises a fastening screw or a fastening nut, which cooperates in the use position of the electrical terminal with a corresponding nut or screw such that an electrically connected to the busbar electrical conductor between the nut or screw and the busbar is clamped.

Aus der GB 2 056 793 A ist eine elektrische Klemme bekannt, welche ein Gehäuse, eine an dem Gehäuse gehaltene Stromschiene und eine Befestigungsschraube aufweist. Die Befestigungsschraube wirkt in der Benutzungslage der elektrischen Klemme mit einer dazu korrespondierenden Mutter derart zusammen, dass ein mit der Stromschiene elektrisch zu verbindender Leiter zwischen der Mutter und der Stromschiene eingeklemmt ist.From the GB 2 056 793 A For example, an electrical terminal is known which has a housing, a bus bar held on the housing, and a fixing screw. The fastening screw cooperates in the position of use of the electrical terminal with a mother corresponding thereto such that a conductor to be electrically connected to the busbar is clamped between the nut and the busbar.

Eine derartige elektrische Klemme ist auch aus der US 6 361 382 B1 bekannt, wobei hier ferner die Mutter senkrecht zur Mittelachse der Mutter von dem Gehäuse eingefasst ist, wobei das Gehäuse in dem Kontaktbereich korrespondierend zu der Außen-kontur der Mutter ausgebildet ist.Such an electrical terminal is also from the US 6,361,382 B1 known, in which case further the mother is bordered perpendicular to the central axis of the nut of the housing, wherein the housing is formed in the contact region corresponding to the outer contour of the nut.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine elektrische Klemme anzugeben, bei der die Drehmomentübertragung von der Befestigungsschraube oder - mutter auf das Gehäuse verbessert ist.The present invention has for its object to provide an electrical terminal in which the torque transmission from the mounting screw or - nut is improved on the housing.

Diese Aufgabe wird durch eine elektrische Klemme mit den Merkmalen des Anspruchs 1 gelöst. Die Unteransprüche betreffen vorteilhafte Weiterbildungen der Erfindung.This object is achieved by an electrical terminal with the features of claim 1. The subclaims relate to advantageous developments of the invention.

Ein wesentlicher Vorteil der erfindungsgemäßen elektrischen Klemme liegt insbesondere darin, dass die Drehmomentübertragung von der Befestigungsschraube oder - mutter auf das Gehäuse verbessert ist. Dadurch, dass in der Montagelage der elektrischen Klemme der Schraubenkopf der Befestigungsschraube an dessen oder die Befestigungsmutter an deren Außenumfang in Richtung senkrecht zu der Mittelachse der Befestigungsschraube oder -mutter vollständig von dem Gehäuse eingefasst ist, wobei das Gehäuse in dem Kontaktbereich korrespondierend zu der Außenkontur der Befestigungsschraube oder -mutter ausgebildet ist, ist die Kontaktfläche zwischen der Befestigungsschraube oder -mutter und dem Gehäuse maximiert, so dass das über die Befestigungsschraube oder -mutter in die elektrische Klemme eingeleitete Drehmoment an das Gehäuse weitergeleitet werden kann, bei gleichzeitiger Reduzierung der mechanischen Beanspruchung in der einzelnen Kontaktfläche. Auf diese Weise können bei der elektrischen Verbindung eines elektrischen Leiters mit der Stromschiene der elektrischen Klemme größere Drehmomente realisiert werden, ohne dabei das Gehäuse der elektrischen Klemme zu beschädigen oder gar zu zerstören. Dies ist gerade bei den sogenannten Bolzenanschlussklemmen von Bedeutung, da diese für elektrische Verbindungsaufgaben ausgewählt werden, bei denen es insbesondere auf einen robusten elektrischen und mechanischen Kontakt und eine weitgehende Wartungsfreiheit ankommt. An dem Gehäuse ist eine Sicherungslasche angeordnet, wobei die Sicherungslasche von einer Öffnungslage in eine Sicherungslage überführbar ist und in der Sicherungslage die Stromschiene in der Montagelage der elektrischen Klemme in Richtung parallel zu der Mittelachse der Befestigungsschraube oder - mutter zwischen dem Gehäuse und der Sicherungslasche fixiert ist. Auf diese Weise ist es zum einen möglich, zur Vereinfachung der Montage der Stromschiene und damit der elektrischen Klemme, ausreichend Spiel zwischen dem Gehäuse und der Stromschiene vorzusehen. Zum anderen gewährleistet die Sicherungslasche die korrekte Lage der Stromschiene in der Benutzungslage der elektrischen Klemme. Die Benutzungslage der elektrischen Klemme ist die Lage, in welcher der elektrische Leiter mit der Stromschiene der elektrischen Klemme in elektrisch leitender Verbindung steht, nämlich zwischen der Mutter oder Schraube und der Stromschiene eingeklemmt ist.An essential advantage of the electrical terminal according to the invention is, in particular, that the torque transmission from the fastening screw or nut to the housing is improved. Characterized in that in the mounting position of the electrical terminal of the screw head of the fastening screw on the or the fastening nut on the outer circumference in the direction perpendicular to the central axis of the fastening screw or nut is completely enclosed by the housing, wherein the housing in the contact region corresponding to the outer contour of Fixing screw or nut is formed, the contact surface between the fastening screw or nut and the housing is maximized, so that the introduced via the fastening screw or nut in the electrical terminal torque can be forwarded to the housing, while reducing the mechanical stress in the single contact surface. In this way, larger torques can be realized in the electrical connection of an electrical conductor to the busbar of the electrical terminal, without damaging the case of the electrical terminal or even destroy it. This is particularly important in the case of the so-called bolt connection terminals, since these are selected for electrical connection tasks, which require, in particular, robust electrical and mechanical contact and extensive freedom from maintenance. A securing tab is arranged on the housing, wherein the securing tab can be moved from an open position into a securing position and in the securing position, the busbar is fixed in the mounting position of the electrical terminal in the direction parallel to the center axis of the fastening screw or nut between the housing and the securing tab , In this way, it is on the one hand possible to simplify the installation of the busbar and Thus, the electrical terminal, sufficient clearance between the housing and the busbar provide. On the other hand, the securing tab ensures the correct position of the busbar in the operating position of the electrical terminal. The position of use of the electrical terminal is the position in which the electrical conductor is in electrically conductive connection with the busbar of the electrical terminal, namely between the nut or screw and the busbar is clamped.

Grundsätzlich ist die elektrische Klemme nach Art, Material und Dimensionierung in weiten geeigneten Grenzen frei wählbar. Dies gilt auch für die Befestigungsschraube oder -mutter sowie die dazu korrespondierende Mutter oder Schraube. Insbesondere ist es aus Kostengründen sinnvoll, hier auf genormte Schrauben und Muttern zurückzugreifen. Besonders vorteilhaft ist es, wenn die Befestigungsschraube oder -mutter und die dazu korrespondierende Mutter oder Schraube als Sechskantschrauben u. - muttern ausgebildet sind, da diese besonders robust und leicht verfügbar sind.Basically, the electrical terminal according to type, material and dimensioning freely selectable within wide suitable limits. This also applies to the fastening screw or nut and the corresponding nut or screw. In particular, it makes sense for cost reasons to resort here to standardized screws and nuts. It is particularly advantageous if the fastening screw or nut and the corresponding nut or screw as hexagon screws u. - Are formed nuts, as they are particularly robust and readily available.

Eine vorteilhafte Weiterbildung sieht vor, dass das Gehäuse ein Sicherungsmittel aufweist, welches die Stromschiene in der Montagelage der elektrischen Klemme in einer Richtung senkrecht zu der Mittelachse der Befestigungsschraube oder -mutter fixiert. Auf diese Weise ist die korrekte Lage der Stromschiene in der Montagelage der elektrischen Klemme in dieser Richtung gewährleistet. Besonders vorteilhaft ist es, wenn das Gehäuse Sicherungsmittel aufweist, welche die Stromschiene in der Montagelage der elektrischen Klemme in beide Richtungen senkrecht zu der Mittelachse der Befestigungsschraube oder -mutter fixiert. Hierdurch ist die Stromschiene in der Ebene senkrecht zu der Mittelachse der Befestigungsschraube oder -mutter festgelegt.An advantageous development provides that the housing has a securing means which fixes the busbar in the mounting position of the electrical terminal in a direction perpendicular to the central axis of the fastening screw or nut. In this way, the correct position of the bus bar is ensured in the mounting position of the electrical terminal in this direction. It when the housing has securing means which fixes the busbar in the mounting position of the electrical terminal in both directions perpendicular to the central axis of the fastening screw or nut is particularly advantageous. As a result, the busbar is fixed in the plane perpendicular to the central axis of the fastening screw or nut.

Grundsätzlich ist die Sicherungslasche nach Art, Material und Anordnung in weiten geeigneten Grenzen frei wählbar. Vorteilhafterweise weist die Sicherungslasche einen Anpressvorsprung auf, wobei der Anpressvorsprung die Stromschiene in der Sicherungslage der Sicherungslasche gegen das Gehäuse vorspannt. Hierdurch ist die Funktion der Sicherungslasche auf konstruktiv einfache und robuste Weise realisiert. Eine besonders vorteilhafte Weiterbildung der beiden vorgenannten Ausführungsformen sieht vor, dass die Sicherungslasche ein Verriegelungsmittel aufweist, das in der Sicherungslage der Sicherungslasche mit einem dazu korrespondierend ausgebildeten Schloss des Gehäuses derart zusammenwirkt, dass die Sicherungslasche in der Sicherungslage fixiert ist. Auf diese Weise ist gewährleistet, dass die Sicherungslasche auch unter schwierigen Einsatzbedingungen, wie beispielsweise bei Vibrationen der elektrischen Klemme, in der Sicherungslage verbleibt. Dabei kann die durch das Verriegelungsmittel und das Schloss gebildete Verbindung je nach Anwendungsfall sowohl lösbar als auch unlösbar ausgebildet sein. Die jeweils geeignete Verbindungstechnik, wie beispielsweise die Rastverbindung, wird der Fachmann aus den ihm bekannten Verbindungstechniken bedarfsgerecht auswählen.Basically, the securing tab on the type, material and arrangement freely selectable within wide appropriate limits. Advantageously, the securing tab has a pressing projection, wherein the pressing projection biases the busbar in the securing position of the securing tab against the housing. As a result, the function of the securing tab is realized in a structurally simple and robust manner. A particularly advantageous development of the two aforementioned embodiments provides that the securing tab has a locking means which cooperates in the securing position of the securing tab with a corresponding thereto designed lock of the housing such that the securing tab is fixed in the securing position. In this way, it is ensured that the securing tab remains in the securing position, even under difficult operating conditions, such as vibration of the electrical terminal. Depending on the application, the connection formed by the locking means and the lock can be designed to be both detachable and non-detachable. The respective suitable connection technology, such as the latching connection, the skilled person from the known connection techniques select as needed.

Eine andere vorteilhafte Weiterbildung der Ausführungsform mit Sicherungslasche sieht vor, dass die Sicherungslasche an dem Gehäuse angeformt ist. Hierdurch ist die Herstellung und Montage der Sicherungslasche vereinfacht und die Sicherungslasche gleichzeitig gegen Verlust gesichert.Another advantageous development of the embodiment with securing tab provides that the securing tab is integrally formed on the housing. As a result, the production and installation of the securing tab is simplified and simultaneously secured the securing tab against loss.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass die Mutter oder Schraube an dem Gehäuse festgelegt ist. Auf diese Weise ist die Mutter oder Schraube, auch wenn die elektrische Klemme noch nicht in die Benutzungslage überführt worden ist, ebenfalls wirksam vor Verlust gesichert.A further advantageous embodiment provides that the nut or screw is fixed to the housing. In this way, even if the electric terminal has not yet been transferred to the use position, the nut or screw is also effectively prevented from being lost.

Grundsätzlich ist die erfindungsgemäße elektrische Klemme als Einzelklemme ausführbar. In vielen Anwendungsfällen ist es jedoch erforderlich, mehrere elektrische Klemmen elektrisch miteinander zu verbinden. Um die einzelnen elektrischen Klemmen zueinander räumlich auszurichten, werden üblicherweise Tragschienen verwendet. Deshalb sieht eine vorteilhafte Weiterbildung vor, dass die elektrische Klemme ein Verbindungsmittel aufweist, mit dem die elektrische Klemme an einer Tragschiene halterbar ist.In principle, the electrical terminal according to the invention can be executed as a single terminal. In many applications, however, it is necessary to electrically connect several electrical terminals together. In order to align the individual electrical terminals to each other spatially, mounting rails are usually used. Therefore, an advantageous development provides that the electrical terminal has a connecting means with which the electrical terminal can be held on a support rail.

Insbesondere bei einer als Reihenklemme ausgebildeten elektrischen Klemme besteht eine vorteilhafte Weiterbildung darin, dass das Gehäuse eine elektrische lsolierwand aufweist, wobei die elektrische Isolierwand aneinander angrenzende elektrische Klemmen voneinander elektrisch isoliert. Hierdurch ist die erforderliche Kriechstromfestigkeit auf konstruktiv besonders einfache Weise realisiert. Dies gilt insbesondere für Ausführungsformen, bei denen die elektrische Klemme mit elektrischen Leitern verbunden werden muss, die keine isolierten Kabelschuhe oder dergleichen aufweisen.In particular, in an electrical terminal designed as a terminal block, an advantageous development is that the housing has an electrical insulating wall, the electrical insulating wall electrically insulating mutually adjacent electrical terminals. As a result, the required tracking resistance is realized in a structurally particularly simple manner. This is especially true for embodiments in which the electrical terminal must be connected to electrical conductors that do not have insulated terminals or the like.
