Description
Die Erfindung richtet sich auf eine Sicherungsklemme.The invention is directed to a fuse terminal.
Sicherungsklemmen, welche aneinandergereiht an einer Tragschiene angeordnet werden können, dienen dazu, in Schaltanlagen, Steuerungen und Geräten die erforderliche Absicherung der Haupt- und Steuerstromkreise vorzunehmen. Sicherungsklemmen haben somit die Aufgabe einer Sicherung als auch der Verteilung eines Potentials.Fuse terminals, which can be arranged side by side on a mounting rail, serve to make the required protection of the main and control circuits in switchgear, controllers and devices. Fuse terminals thus have the task of securing as well as the distribution of a potential.
Aus dem Stand der Technik sind beispielsweise Sicherungsklemmen bekannt, bei welchen das Sicherungselement mit einer Schraubkappe senkrecht in das Gehäuse der Sicherungsklemme eingeschraubt wird. Nachteilig hierbei ist, dass eine große Klemmenteilung von ≥ 12 mm erforderlich ist. Zudem ist die Handhabung beim Einsetzen und Lösen des Sicherungselementes in der Sicherungsklemme umständlich.From the prior art, for example, fuse terminals are known in which the fuse element is screwed with a screw vertically into the housing of the fuse terminal. The disadvantage here is that a large terminal pitch of ≥ 12 mm is required. In addition, the handling when inserting and loosening the fuse element in the fuse terminal is cumbersome.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Sicherungsklemme zur Verfügung zu stellen, mittels welcher die Klemmenteilung reduziert und die Handhabung der Sicherungsklemme vereinfacht werden kann.The invention is therefore based on the object to provide a fuse terminal available, by means of which the Klemmenteilung reduced and the handling of the fuse terminal can be simplified.
Bei einer Sicherungsklemme der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass die Sicherungsklemme ein Gehäuse, einen verschwenkbar an dem Gehäuse angeordneten Sicherungsträger und ein Sicherungselement aufweist, wobei der Sicherungsträger einen Schwenkarm aufweist, an welchem ein Aufnahmeelement, in welchem das Sicherungselement eingesetzt ist, derart angeordnet ist, dass das Sicherungselement mit seiner Längsachse in einem Winkel von im Wesentlichen 90° zur Längsachse des Schwenkarmes angeordnet ist, so dass das Sicherungselement mittels einer Verschwenkbewegung des Sicherungsträgers in eine senkrecht in dem Gehäuse ausgebildete Öffnung einführbar ist.In a fuse terminal of the type described in more detail, this object is achieved in that the fuse terminal comprises a housing, a pivotally mounted on the housing fuse carrier and a fuse element, wherein the fuse carrier has a pivot arm on which a receiving element, in which the fuse element used is arranged such that the securing element with its longitudinal axis at an angle of substantially 90 ° to Longitudinal axis of the pivot arm is arranged so that the securing element can be inserted by means of a pivoting movement of the fuse carrier in a vertically formed in the housing opening.
Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.
Die Sicherungsklemme gemäß der Erfindung zeichnet sich dadurch aus, dass das Sicherungselement nun nicht mehr mittels einer Schraubkappe in einer in dem Gehäuse ausgebildeten Öffnung eingeschraubt wird, sondern mittels eines Schwenkarmes eines Sicherungsträgers in die Öffnung eingeschwenkt wird, um das Sicherungselement in der Öffnung des Gehäuses zu positionieren. Das Sicherungselement ist hierfür in einem an dem Schwenkarm ausgebildeten Aufnahmeelement angeordnet. Der Sicherungsträger bzw. der Schwenkarm des Sicherungsträgers ist verschwenkbar an dem Gehäuse angeordnet bzw. gelagert, so dass das in dem Aufnahmeelement des Sicherungsträgers angeordnete Sicherungselement verliersicher über den Sicherungsträger unmittelbar an dem Gehäuse gelagert ist, auch wenn das Sicherungselement nicht in die Öffnung des Gehäuses eingeführt ist. Die verschwenkbare Anordnung des Sicherungselementes über den Sicherungsträger an dem Gehäuse ermöglicht zudem eine vereinfachte Handhabung beim Einführen des Sicherungselementes in die Öffnung des Gehäuses und beim Entfernen des Sicherungselementes aus der Öffnung des Gehäuses. Das Aufnahmeelement, mit dem das Sicherungselement zusammen in die Öffnung des Gehäuses einführbar ist, ist vorzugsweise an die Kontur bzw. die Außenabmessungen des Sicherungselementes angepasst und liegt unmittelbar an der Außenumfangsfläche des Sicherungselementes an, so dass möglichst wenig zusätzlicher Bauraum in der Sicherungsklemme für das Aufnahmeelement notwendig ist. Das Aufnahmeelement ist vorzugsweise in der Art eines Käfigs ausgebildet, welcher das Sicherungselement nur bereichsweise umschließt und nicht die gesamte Außenumfangsfläche des Sicherungselementes abdeckt. Das Sicherungselement und damit auch das Aufnahmeelement ist gemäß der Erfindung mit seiner Längsachse in einem Winkel von im Wesentlichen 90° zur Längsachse des Schwenkarmes angeordnet, so dass das Sicherungselement bei einer Verschwenkbewegung senkrecht in dem Gehäuse angeordnet werden kann. Durch die senkrechte Anordnung des Sicherungselementes in dem Gehäuse wird die Breite der Sicherungsklemme durch das Sicherungselement kaum beeinflusst, so dass die Baugröße der Sicherungsklemme möglichst klein, mit einer möglichst geringen Breite ausgebildet sein kann. Eine senkrechte Anordnung des Sicherungselementes in dem Gehäuse bedeutet, dass das Sicherungselement mit seiner Längsachse in einem Winkel von 90° zur Oberseite bzw. zur Unterseite, mit welcher die Sicherungsklemme an einer Tragschiene aufgerastet ist, des Gehäuses der Sicherungsklemme angeordnet ist. Das Gleiche gilt auch für die senkrecht in dem Gehäuse ausgebildete Öffnung. Mittels der Sicherungsklemme gemäß der Erfindung ist es somit möglich, die Klemmenteilung der Sicherungsklemme zu reduzieren, die Handhabung zu vereinfachen und die Baugröße der Sicherungsklemme möglichst weit zu reduzieren. Ferner können mehrere derartiger Sicherungsklemmen konturgleich in vorhandene Klemmenbaureihen integriert werden.The fuse terminal according to the invention is characterized in that the fuse element is no longer screwed by means of a screw cap in an opening formed in the housing, but is pivoted by means of a pivot arm of a fuse carrier in the opening to the fuse element in the opening of the housing position. The securing element is arranged for this purpose in a receiving element formed on the swivel arm. The fuse carrier or the swivel arm of the fuse carrier is pivotably arranged or mounted on the housing, so that the arranged in the receiving element of the fuse carrier fuse element is stored captive on the fuse carrier directly to the housing, even if the fuse element is not inserted into the opening of the housing is. The pivotal arrangement of the fuse element on the fuse carrier to the housing also allows for easier handling during insertion of the fuse element in the opening of the housing and the removal of the fuse element from the opening of the housing. The receiving element, with which the securing element can be inserted together into the opening of the housing, is preferably adapted to the contour or the outer dimensions of the securing element and is located directly on the outer peripheral surface of the Fuse element, so that as little additional space in the fuse terminal for the receiving element is necessary. The receiving element is preferably designed in the manner of a cage, which surrounds the securing element only partially and does not cover the entire outer peripheral surface of the securing element. The securing element and thus also the receiving element is arranged according to the invention with its longitudinal axis at an angle of substantially 90 ° to the longitudinal axis of the pivot arm, so that the securing element can be arranged vertically in a pivoting movement in the housing. Due to the vertical arrangement of the fuse element in the housing, the width of the fuse terminal is hardly affected by the fuse element, so that the size of the fuse terminal as small as possible, can be formed with the smallest possible width. A vertical arrangement of the fuse element in the housing means that the fuse element is arranged with its longitudinal axis at an angle of 90 ° to the top or bottom, with which the fuse terminal is latched to a mounting rail of the housing of the fuse terminal. The same applies to the vertically formed in the housing opening. By means of the fuse terminal according to the invention, it is thus possible to reduce the terminal pitch of the fuse terminal, to simplify the handling and to reduce the size of the fuse terminal as far as possible. Furthermore, several such fuse terminals can be integrated into existing terminal block series with the same shape.
Nach einer bevorzugten Ausgestaltung der Erfindung sind in dem Gehäuse ein erstes Kontaktelement, welches das Sicherungselement in einem in die Öffnung eingeführten Zustand des Sicherungselementes an einem ersten Ende des Sicherungselementes kontaktiert, und ein zweites Kontaktelement, welches das Sicherungselement in dem in die Öffnung eingeführten Zustand des Sicherungselementes an einem dem ersten Ende gegenüberliegenden zweiten Ende des Sicherungselementes kontaktiert, angeordnet. Die beiden Kontaktelemente sind vorzugsweise mit jeweils einem Leiteranschlusskörper, welche in Form beispielsweise eines Schraubanschlusskörpers oder Lötanschlusskörpers ausgebildet sein können, verbunden. Die Verbindung erfolgt vorzugsweise mit einem Metallstreifen, welcher sich von einem Kontaktelement zu einem dem Kontaktelement zugeordneten Leiteranschlusskörper erstreckt und vorzugsweise bis in den Leiteranschlusskörper hineinragt, so dass der Metallstreifen und damit das Kontaktelement über den Metallstreifen unmittelbar mit einem in dem Leiteranschlusskörper eingeführten Leiter in Kontakt kommen kann. An dem ersten Ende und dem zweiten Ende des Sicherungselementes ist vorzugsweise jeweils eine metallische Kontaktkappe angeordnet, an welchen die Kontaktelemente kontaktierend anliegen können. Somit ist es möglich zwei Kontaktelemente und damit auch zwei Leiteranschlusskörper mit einem Sicherungselement zu verbinden.According to a preferred embodiment of the invention, in the housing, a first contact element, which introduced the securing element in a in the opening State of the securing element contacted at a first end of the securing element, and a second contact element, which contacts the securing element in the inserted into the opening state of the securing element at a first end opposite the second end of the securing element arranged. The two contact elements are preferably each connected to a conductor connection body, which may be in the form of, for example, a screw connection body or solder connection body. The connection is preferably made with a metal strip, which extends from a contact element to a contact element associated conductor terminal body and preferably protrudes into the conductor terminal body, so that the metal strip and thus the contact element via the metal strip directly come into contact with an inserted conductor in the body conductor can. At the first end and the second end of the securing element, a metallic contact cap is preferably arranged in each case, against which the contact elements can bear in contact. Thus, it is possible to connect two contact elements and thus also two conductor connection body with a fuse element.
Weiter ist es bevorzugt vorgesehen, dass das erste Kontaktelement und das zweite Kontaktelement im Wesentlichen u-förmig ausgebildet sind und das erste Kontaktelement und das zweite Kontaktelement das Sicherungselement im eingeführten Zustand jeweils an seinem Außenumfang umgreifen. Die Kontaktelemente sind dabei vorzugsweise aus einem Metallstreifen oder Metallband ausgebildet, welches u-förmig gebogen ist. Durch die u-förmige Ausgestaltung der Kontaktelemente kann das Sicherungselement in den Kontaktelementen zwischen zwei die U-Form ausbildenden Kontaktarmen geklemmt gehalten werden, ohne dass hierbei weitere zusätzliche Bauteile notwendig sind. Somit zeichnen sich die Kontaktelemente durch eine einfache Ausgestaltung aus, bei welcher gleichzeitig eine sichere Kontaktierung der Kontaktelemente mit dem Sicherungselement gewährleistet werden kann, indem die u-förmig ausgebildeten Kontaktelemente das Sicherungselement im eingeführten Zustand jeweils an seinem Außenumfang, wobei der Außenumfang vorzugsweise durch die an den beiden Enden des Sicherungselementes angeordneten Kontaktkappen ausgebildet ist, umgreifen.Further, it is preferably provided that the first contact element and the second contact element are substantially U-shaped and the first contact element and the second contact element embrace the securing element in the inserted state in each case on its outer circumference. The contact elements are preferably formed of a metal strip or metal strip, which is bent in a U-shape. Due to the U-shaped configuration of the contact elements, the Fuse element are kept clamped in the contact elements between two U-shape forming contact arms, without this additional additional components are necessary. Thus, the contact elements are characterized by a simple configuration, in which at the same time a secure contact of the contact elements with the fuse element can be ensured by the U-shaped contact elements, the fuse element in the inserted state respectively on its outer periphery, the outer circumference preferably by the formed the two ends of the fuse element arranged contact caps, embrace.
Das erste im Wesentlichen u-förmig ausgebildete Kontaktelement und das zweite im Wesentlichen u-förmig ausgebildete Kontaktelement weist weiter vorzugsweise jeweils eine Einführöffnung zur Aufnahme des Sicherungselementes auf, über welche das Sicherungselement in das erste Kontaktelement und das zweite Kontaktelement einführbar ist, wobei die Querschnittsfläche der Einführöffnung des ersten Kontaktelementes senkrecht zu der Querschnittsfläche der Einführöffnung des zweiten Kontaktelementes ausgebildet ist. Die Einführöffnungen des ersten Kontaktelementes und des zweiten Kontaktelementes sind somit vorzugsweise nicht in die gleiche Richtung zeigend ausgebildet, sondern in einem Winkel von 90° verdreht zueinander angeordnet. Die beiden Kontaktelemente sind dabei vorzugsweise derart in dem Gehäuse angeordnet, dass das Sicherungselement mit seiner Stirnseitenfläche des ersten Endes im eingeführten Zustand in dem ersten Kontaktelement anliegt, so dass das erste Kontaktelement das Sicherungselement entlang seiner Längsachse umgreift. Das zweite Kontaktelement umgreift hingegen das Sicherungselement quer zu seiner Längsachse, so dass das Sicherungselement im eingeführten Zustand mit seiner Längsseitenfläche an dem zweiten Kontaktelement anliegt. Hierdurch kann das Sicherungselement besonders verrutschsicher in den beiden Kontaktelementen gehalten werden, um eine sichere Kontaktierung auch bei Erschütterungen oder einem Transport der Sicherungsklemme gewährleisten zu können.The first substantially U-shaped contact element and the second substantially U-shaped contact element further preferably each have an insertion opening for receiving the securing element, via which the securing element in the first contact element and the second contact element is insertable, wherein the cross-sectional area of Insertion opening of the first contact element is formed perpendicular to the cross-sectional area of the insertion opening of the second contact element. The insertion of the first contact element and the second contact element are thus preferably not shown pointing in the same direction, but rotated at an angle of 90 ° to each other. The two contact elements are preferably arranged in such a way in the housing, that the securing element abuts with its end face of the first end in the inserted state in the first contact element, so that the first contact element engages around the securing element along its longitudinal axis. The second contact element, however, surrounds the securing element transversely to its longitudinal axis, so that the Fuse element in the inserted state rests with its longitudinal side surface on the second contact element. As a result, the securing element can be held in a particularly slip-proof manner in the two contact elements in order to be able to ensure a secure contact even in the event of vibrations or transport of the securing clamp.
Das Aufnahmeelement ist bevorzugt derart ausgebildet, dass das Aufnahmeelement zwei sich gegenüberliegend angeordnete Stegelement aufweist, zwischen denen das Sicherungselement geklemmt gehalten ist. Durch die Ausbildung des Aufnahmeelementes im Wesentlichen aus den zwei Stegelementen, wird die Außenumfangsfläche des Sicherungselementes nur in einem relativ geringen Bereich von dem Aufnahmeelement abgedeckt, so dass die mögliche Kontaktierungsfläche des Sicherungselementes zur Kontaktierung mit den Kontaktelementen möglichst groß ist. Zudem weist das Aufnahmeelement dadurch eine einfache Ausgestaltung auf, welche wenig Bauraum benötigt, und das Sicherungselement zudem leicht in das Aufnahmeelement eingebracht und wieder aus dem Aufnahmeelement gelöst werden kann.The receiving element is preferably designed such that the receiving element has two oppositely arranged web element, between which the securing element is held clamped. Due to the design of the receiving element substantially of the two web elements, the outer peripheral surface of the securing element is covered only in a relatively small area of the receiving element, so that the possible contacting surface of the fuse element for contacting with the contact elements is as large as possible. In addition, the receiving element thereby has a simple configuration, which requires little space, and the securing element can also be easily inserted into the receiving element and released from the receiving element again.
Zur sicheren Halterung des Sicherungselementes in dem Halteelement weisen die beiden Stegelemente vorzugsweise jeweils einen Einrastbereich zum Klemmen des Sicherungselementes auf.For secure retention of the securing element in the holding element, the two web elements preferably each have a latching area for clamping the securing element.
Um ferner die Handhabung der Sicherungsklemme für einen Benutzer zu erleichtern, ist es bevorzugt vorgesehen, dass der Sicherungsträger ein an dem Schwenkarm angeordnetes Griffelement aufweist. Das Griffelement ist vorzugsweise an einem freien Ende des Schwenkarmes angeordnet und ist bevorzugt in Form eines Steges ausgebildet, welcher winklig, d. h. in einem Winkel von vorzugsweise 5° - 60°, zu der Längsachse des Schwenkarmes an dem Schwenkarm angeordnet ist. Ferner weist das Griffelement vorzugsweise eine geriffelt ausgebildete Seitenfläche auf, um ein Abrutschen von dem Griffelement beim Betätigen des Sicherungsträgers zu verhindern und dadurch die Handhabung der Sicherungsklemme zu verbessern.In order to further facilitate the handling of the fuse terminal for a user, it is preferably provided that the fuse carrier has a arranged on the pivot arm grip element. The gripping element is preferably arranged at a free end of the swivel arm and is preferably formed in the form of a web which is arranged at an angle, ie at an angle of preferably 5 ° - 60 °, to the longitudinal axis of the pivot arm on the pivot arm. Furthermore, the gripping element preferably has a serrated side surface to prevent slippage of the handle member when operating the fuse carrier, thereby improving the handling of the fuse terminal.
Zudem ist es nach einer bevorzugten Ausgestaltung der Erfindung vorgesehen, dass der Sicherungsträger eine Beschriftungsfläche aufweist, über welche die Sicherungsklemme gekennzeichnet werden kann. Die Beschriftungsfläche ist vorzugsweise an dem Schwenkarm des Sicherungsträgers ausgebildet, so dass die Beschriftungsfläche für einen Benutzer gut zu erkennen ist.Moreover, it is provided according to a preferred embodiment of the invention that the fuse carrier has a labeling surface over which the fuse terminal can be marked. The labeling surface is preferably formed on the pivot arm of the fuse carrier, so that the labeling surface is easy to recognize for a user.
Nachfolgend wird die Erfindung unter Bezugnahme auf die anliegenden Zeichnungen anhand einer bevorzugten Ausführungsform der Erfindung näher erläutert.The invention with reference to the accompanying drawings with reference to a preferred embodiment of the invention will be explained in more detail.

Das Aufnahmeelement 5 ist rechteckförmig ausgebildet und besteht im Wesentlichen aus zwei parallel zueinander angeordneten Stegelementen 13, 14, zwischen denen das Sicherungselement 3 geklemmt gehalten wird. Die beiden Stegelemente 13, 14 erstrecken sich entlang der Längsseitenflächen des Sicherungselementes 3. Die beiden Stegelemente 13, 14 sind mit einem ersten Verbindungssteg 15 und einem dem ersten Verbindungssteg 15 gegenüberliegenden zweiten Verbindungssteg 16 verbunden, wobei das Sicherungselement 3 mit seinen beiden Stirnseitenflächen an jeweils einem Verbindungssteg 15, 16 anliegt. Der Bereich zwischen den beiden Stegelementen 13, 14 ist frei, so dass das Sicherungselement in diesen Bereichen seiner Längsseitenfläche nicht von dem Aufnahmeelement 5 abgedeckt ist. Um das Sicherungselement 3 sicher in dem Abdeckelement 5 halten zu können, weisen die beiden Stegelemente 13, 14 jeweils einen Einrastbereich 17, 18 zum Klemmen des Sicherungselementes 3 auf. Die beiden Einrastbereiche 17, 18 sind an den beiden Stegelementen 13, 14 gegenüberliegend zueinander ausgebildet. Die beiden Einrastbereiche 17, 18 weisen jeweils eine größere Breite auf als die Stegelemente 13, 14, so dass im Bereich der Einrastbereiche 17, 18 eine größere Fläche des Außenumfangs des Sicherungselementes 3 abgedeckt wird und an dem Außenumfang anliegt. Die in Richtung Sicherungselement 3 zeigende Fläche der Einrastbereiche 17, 18 ist gewölbt ausgebildet, so dass die Einrastbereiche 17, 18 an den zylinderförmigen Außenumfang des Sicherungselementes 3 angepasst sind und dadurch eine verkippsichere Befestigung des Sicherungselementes 3 in dem Aufnahmeelement 5 möglich ist. Die Einrastbereiche 17, 18 sind derart positioniert, dass sie das Sicherungselement 3 mittig halten.The
