Die Batteriepolklemme 1 weist ferner ein Klemmelement 3, ein Schraubelement 4 und ein Schraubgegenelement 5 auf. Das Schraubelement 4 und das Klemmelement 3 sind einstückig ausgebildet. Das Schraubelement 4 und das Schraubgegenelement 5 sind so ausgebildet, dass diese miteinander verschraubbar sind.The
Bei einem Schraubvorgang in Schließrichtung wird das Klemmelement 3 entlang der Rotationsachse des Schraubelements 4 in Richtung einer Oberkante des Ringabschnitts 2 gezogen. Dadurch klemmt das Klemmelement 3 nach vorne stehende Bereiche des Ringabschnitts 2 derart, dass sich der Innendurchmesser des Ringabschnitts 2 verringert. An einer Oberkante weist der Ringabschnitt 2 einen geringeren Innendurchmesser auf als an einer Unterkante.During a screwing operation in the closing direction, the clamping
Das Schraubelement 4 weist ein Außengewinde auf. Das Schraubgegenelement 5 weist ein Innengewinde auf.The
Bei einem Schraubvorgang zwischen Schraubelement 4 und Schraubgegenelement 5 werden Kräfte um die Rotationsachse des Schraubgegenelements 5 auf die Angriffsfläche 8 des Schraubgegenelements 5 eingebracht. Dadurch bewegen sich Schraubelement 4 und Schraubgegenelement 5 relativ zueinander um deren Rotationsachse, wodurch aufgrund des Innengewindes und des Außengewindes eine Relativbewegung zwischen Schraubelement 4 und Schraubgegenelement 5 entlang der Rotationsachse des Schraubelements 4 und des Schraubgegenelements 5 hervorgerufen wird.In a screwing between the
Die Rotationsachse des Schraubelements 4, des Schraubgegenelements 5 und des Ringabschnitts 2 liegen parallel zueinander, wodurch insbesondere ein Verschrauben von oben ermöglicht wird.The axis of rotation of the
Die Batteriepolklemme weist eine Federelement 6 auf. Das Federelement 6 umschließt die Angriffsfläche 8 des Schraubgegenelements 5 derart, dass, ohne Krafteinwirkung auf das Federelement 6 entlang der Richtung der Rotationsachse des Schraubelements 4 und/oder des Schraubgegenelements 5, keine Krafteinwirkung auf die Angriffsfläche 8 in eine Richtung um die Rotationsachse des Schraubgegenelements 5 möglich ist.The battery pole terminal has a

Sofern sich im Laufe des Verfahrens herausstellt, dass ein Merkmal oder eine Gruppe von Merkmalen nicht zwingend nötig ist, so wird anmelderseitig bereits jetzt eine Formulierung zumindest eines unabhängigen Anspruchs angestrebt, welcher das Merkmal oder die Gruppe von Merkmalen nicht mehr aufweist. Hierbei kann es sich beispielsweise um eine Unterkombination eines am Anmeldetag vorliegenden Anspruchs oder um eine durch weitere Merkmale eingeschränkte Unterkombination eines am Anmeldetag vorliegenden Anspruchs handeln. Derartige neu zu formulierende Ansprüche oder Merkmalskombinationen sind als von der Offenbarung dieser Anmeldung mit abgedeckt zu verstehen.If, in the course of the procedure, it turns out that a feature or a group of features is not absolutely necessary, it is already desired on the applicant side to formulate at least one independent claim which no longer has the feature or the group of features. This may, for example, be a subcombination of a claim present at the filing date or a subcombination of a claim limited by further features of a claim present at the filing date. Such newly formulated claims or feature combinations are to be understood as covered by the disclosure of this application.
Es sei ferner darauf hingewiesen, dass Ausgestaltungen, Merkmale und Varianten der Erfindung, welche in den verschiedenen Ausführungen oder Ausführungsbeispielen beschriebenen und/oder in den Figuren gezeigt sind, beliebig untereinander kombinierbar sind. Einzelne oder mehrere Merkmale sind beliebig gegeneinander austauschbar. Hieraus entstehende Merkmalskombinationen sind als von der Offenbarung dieser Anmeldung mit abgedeckt zu verstehen.It should also be noted that embodiments, features and variants of the invention, which are described in the various embodiments or embodiments and / or shown in the figures, can be combined with each other as desired. Single or multiple features are arbitrary against each other interchangeable. Resulting combinations of features are to be understood as covered by the disclosure of this application.
Rückbezüge in abhängigen Ansprüchen sind nicht als ein Verzicht auf die Erzielung eines selbständigen, gegenständlichen Schutzes für die Merkmale der rückbezogenen Unteransprüche zu verstehen. Diese Merkmale können auch beliebig mit anderen Merkmalen kombiniert werden.Recoveries in dependent claims are not to be understood as a waiver of obtaining independent, objective protection for the features of the dependent claims. These features can also be combined as desired with other features.
Merkmale, die lediglich in der Beschreibung offenbart sind oder Merkmale, welche in der Beschreibung oder in einem Anspruch nur in Verbindung mit anderen Merkmalen offenbart sind, können grundsätzlich von eigenständiger erfindungswesentlicher Bedeutung sein. Sie können deshalb auch einzeln zur Abgrenzung vom Stand der Technik in Ansprüche aufgenommen werden.Features that are disclosed only in the specification or features that are disclosed in the specification or in a claim only in conjunction with other features may, in principle, be of independent significance to the invention. They can therefore also be included individually in claims to distinguish them from the prior art.
