Das Verriegelungselement ist in einer Verschlussstellung mit dem Gehäuse verrastbar. DE 10 2013 107 292 A1 discloses a connection device having a housing and a locking element rotatably held on the housing. The locking element can be locked in a closed position with the housing.

Es ist die Aufgabe der vorliegenden Erfindung eine Anschlusseinrichtung bereitzustellen, die einfach zu warten ist, eine einfache und sichere Handhabung ermöglicht und die in sicherer Weise mit der Sammelschiene verbunden werden kann.It is the object of the present invention to provide a connection device which is easy to maintain, enables easy and safe handling and which can be securely connected to the busbar.

Erfindungsgemäß wird diese Aufgabe durch eine Einrichtung nach Anspruch 1 gelöst.According to the invention, this object is achieved by a device according to claim 1.

Erfindungsgemäß umfasst die Anschlusseinrichtung eine Federkraftklemme, eine Leiteranschlusseinrichtung, die mit der Federkraftklemme elektrisch leitend verbunden ist, und ein Isolierstoffgehäuse, das einen Gehäuseabschnitt aufweist. Die Federkraftklemme und die Leiteranschlusseinrichtung sind in dem Gehäuseabschnitt aufgenommen. Der Gehäuseabschnitt weist eine Aufstecknut zur Aufnahme eines Teilstücks der Sammelschiene auf. Die Federkraftklemme ragt in die Aufstecknut hinein, um mit dem Teilstück in Berührung gebracht zu werden und die Federkraftklemme elektrisch leitend mit der Sammelschiene zu verbinden. Das Isolierstoffgehäuse umfasst einen Verschlussabschnitt, der geeignet ist, eine Öffnungsstellung und eine Verschlussstellung einzunehmen. Die Anschlusseinrichtung ist in der Öffnungsstellung in einer annähernd quer zu einer Erstreckungsrichtung der Sammelschiene verlaufenden Aufsteckrichtung auf die Sammelschiene aufsteckbar, um das Teilstück in der Aufstecknut aufzunehmen. Der Verschlussabschnitt verschließt die Aufstecknut in der Verschlussstellung, um das Teilstück in der Verschlussstellung formschlüssig in der Aufstecknut zu halten. Der Verschlussabschnitt ist auf dem Gehäuseabschnitt beweglich gehalten. Der Verschlussabschnitt ist durch eine Bewegung in einer annähernd orthogonal zur Aufsteckrichtung verlaufenden Verschieberichtung von der Öffnungsstellung in die Verschlussstellung überführbar.According to the invention, the connection device comprises a spring-loaded terminal, a conductor connection device which is electrically conductively connected to the spring-loaded terminal, and an insulating material housing which has a housing section. The spring-loaded terminal and the conductor connection device are accommodated in the housing section. The housing section has an attachment groove for receiving a portion of the busbar. The spring clamp protrudes into the slip-on groove to be brought into contact with the section and to electrically connect the spring-loaded terminal to the busbar. The insulating housing comprises a closure portion which is adapted to assume an open position and a closed position. The connection device can be plugged onto the busbar in the open position in a mounting direction extending approximately transversely to an extension direction of the busbar, in order to receive the section in the attachment groove. The closure portion closes the Aufstecknut in the closed position to hold the portion in the closed position positively in the Aufstecknut. The closure portion is movably supported on the housing portion. The closure portion can be transferred from the open position to the closed position by movement in a direction of displacement in an approximately orthogonal direction to the slip-on direction.

Durch die erfindungsgemäße Ausgestaltung ist die Anschlusseinrichtung in einfacher und sicherer Weise mit der Sammelschiene verbindbar. Nimmt der Verschlussabschnitt die Verschlussstellung ein, so ist die Anschlusseinrichtung formschlüssig mit dem Teilstück der Sammelschiene verbunden und ein versehentliches Abreißen der Anschlusseinrichtung von der Sammelschiene wird erschwert. Nimmt der Verschlussabschnitt die Öffnungsstellung ein, so kann die Anschlusseinrichtung durch eine Bewegung entgegen der Aufsteckrichtung in einfacher Weise von der Sammelschiene entfernt werden.As a result of the embodiment according to the invention, the connection device can be connected to the busbar in a simple and reliable manner. If the closure section adopts the closed position, then the connection device is connected in a form-fitting manner to the section of the busbar and an inadvertent tearing of the connection device from the busbar is made more difficult. If the closure section assumes the open position, then the connection device can be removed from the busbar in a simple manner by a movement counter to the attachment direction.
