Die vorliegende Erfindung betrifft eine Verbindungsvorrichtung zum lösbaren Verbinden von elektrischen Verbindungen, beispielsweise zwischen einem Akkumulator und einer elektrischen Werkzeugmaschine oder einem Akkumulator und einer Ladevorrichtung. Darüber hinaus betrifft die vorliegende Erfindung eine Anschlussbuchse als Bestandteil und zur Verbindung mit der Verbindungsvorrichtung sowie eine Trägereinrichtung als Bestandteil der Verbindungsvorrichtung.The present invention relates to a connecting device for releasably connecting electrical connections, for example between an accumulator and an electric machine tool or an accumulator and a charging device. In addition, the present invention relates to a connection socket as a component and for connection to the connecting device and a carrier device as a component of the connecting device.
Elektrische Werkzeugmaschinen und Akkumulatoren können mit Hilfe einer elektrischen Verbindungsvorrichtung miteinander verbunden werden. Häufig handelt es sich dabei um eine wiederlösbare Verbindung. Die Werkzeugmaschine besitzt hierzu elektrische Kontakte (auch Stecker genannt), die in entsprechend ausgestaltete Anschlussbuchsen an dem Akkumulator eingeführt werden, wenn der Akkumulator mit der Werkzeugmaschine verbunden ist. Es ist jedoch auch möglich, dass die Werkzeugmaschine die Anschlussbuchsen und der Akkumulator die elektrischen Kontakte aufweist.Electric machine tools and accumulators can be connected to one another with the aid of an electrical connection device. Often this is a releasable connection. For this purpose, the machine tool has electrical contacts (also called plugs) which are inserted into correspondingly configured connection sockets on the accumulator when the accumulator is connected to the machine tool. However, it is also possible for the machine tool to have the connection sockets and the accumulator to have the electrical contacts.
Darüber hinaus werden auch Ladevorrichtungen mit Akkumulatoren mittels einer elektrischen Verbindungsvorrichtung miteinander verbunden. Die Ladevorrichtung verfügt dabei über elektrische Kontakte, die in entsprechend ausgestaltete Anschlussbuchsen an dem Akkumulator eingeführt werden, wenn der Akkumulator mit der Werkzeugmaschine verbunden ist. Es ist jedoch ebenfalls möglich, dass die Ladevorrichtung die Anschlussbuchsen und der Akkumulator die elektrischen Kontakte aufweist.In addition, charging devices with accumulators are also connected to one another by means of an electrical connection device. The charging device has electrical contacts that are inserted into correspondingly configured connection sockets on the accumulator when the accumulator is connected to the machine tool. However, it is also possible for the charging device to have the connection sockets and the accumulator to have the electrical contacts.
Aufgrund der immer größer werdenden Leistungsfähigkeit von Akkumulatoren und der damit verbundene Anstieg der zur Verfügung stehenden Stromstärke, die zwischen dem Akkumulator und der Werkzeugmaschine fließen kann, stoßen herkömmliche elektrische Verbindungsvorrichtung sowie deren Kontakte und Anschlussbuchsen an ihre physikalischen Grenzen. Beschädigungen an den Verbindungsvorrichtungen sowie an deren Kontakten und Anschlussbuchsen können hierbei entstehen. Gelöst wird dieses Problem häufig dadurch, dass die Dimensionen der Kontakte und Anschlussbuchsen entsprechend vergrößert werden. Alternativ wird die von dem leistungsstarken Akkumulator zur Verfügung stehende Stromstärke gedrosselt, um mögliche Beschädigungen gar nicht erst auftreten zu lassen. Diese bestehenden Lösungen haben dabei den Nachteil, dass sie zu groß, zu teuer und/oder zu aufwendig in der Herstellung sind. Durch die Drosselung der Stromstärke wird wiederum dem Anwender nicht die volle Leistungsfähigkeit der Werkzeugmaschine oder der Ladevorrichtung zur Verfügung gestellt.Due to the ever increasing capacity of accumulators and the associated increase in the available current that can flow between the accumulator and the machine tool, conventional electrical connection devices and their contacts and connection sockets are reaching their physical limits. Damage to the connection devices as well as their contacts and connection sockets can occur. This problem is often solved by enlarging the dimensions of the contacts and connection sockets accordingly. Alternatively, the current strength available from the powerful accumulator is throttled in order to prevent possible damage from occurring in the first place. These existing solutions have the disadvantage that they are too large, too expensive and / or too complex in terms of size Manufacturing are. The throttling of the current strength, in turn, does not provide the user with the full performance of the machine tool or the charging device.
Ein weiteres Problem an herkömmlichen Verbindungsvorrichtungen besteht darin, dass diese für gewöhnlich nicht modular/flexibel an die entsprechende Leistungsfähigkeit bzw. maximale Stromstärke des Akkumulators angepasst werden können. Sowohl die Herstellung als auch die Bereitstellung unterschiedlichster Verbindungsvorrichtungen angepasst auf die jeweilige Leistungsfähigkeit bzw. maximale Stromstärke des jeweils zu verwendenden Akkumulators beinhaltet hohe Kosten sowie einen hohen Verwaltungsaufwand.Another problem with conventional connecting devices is that they usually cannot be adapted in a modular / flexible manner to the corresponding performance or maximum current strength of the accumulator. Both the production and the provision of a wide variety of connection devices, adapted to the respective performance or maximum current strength of the respective battery to be used, involve high costs and high administrative effort.

Die erfindungsgemäße Verbindungsvorrichtung 1 zum lösbaren Verbinden von elektrischen Verbindungen, beispielsweise zwischen einem Akkumulator und einer elektrischen Werkzeugmaschine oder einem Akkumulator und einer Ladevorrichtung enthält im Wesentlichen eine Trägereinrichtung 2 und eine oder mehrere Anschlussbuchsen 3. Die Verbindungsvorrichtung 1 und insbesondere die Anschlussbuchsen 3 dienen primär dazu ein Kontaktelement aufnehmen und somit eine elektrische Verbindung zwischen der Verbindungsvorrichtung 1 bzw. den Anschlussbuchsen 3 herzustellen. Das Kontaktelement kann auch als Tab, Schwert oder Schwertelement bezeichnet werden.The connecting

Das Anbindungselement 5 dient zur Verbindung der Verbindungsvorrichtung 1 mit der Steuerungseinrichtung bzw. der Elektronik einer Werkzeugmaschine, Ladeeinrichtung oder Akkumulator, je nachdem, ob die Verbindungsvorrichtung 1 in einer Werkzeugmaschine, Ladeeinrichtung oder einem Akkumulator enthalten ist. Das Anbindungselement 5 kann mittels eines Kabels oder einer Litze, welche mit dem Anbindungselement 5 gecrimpt, gelötet oder geschweißt ist, an die Steuerungseinrichtung bzw. der Elektronik verbunden sein. In den Figuren ist weder die Steuerungseinrichtung, Elektronik, das Kabel noch die Litze dargestellt.The connecting
Der Grundkörper 4 der Trägereinrichtung 2 erstreckt sich in länglicher Form und enthält dabei ein erstes Ende 4a, ein zweites Ende 4b, ein Bodenelement 4c, ein erstes Seitenelement 6 und ein zweites Seitenelement 7. Der Grundkörper 4 besteht aus einem elektrisch leitfähigen Material. Sowohl das erste Seitenelement 6 als auch das zweite Seitenelement 7 enthalten jeweils eine erste Seitenkante 6a, 7a und eine zweite Seitenkante 6b, 7b. Die beiden Seitenelemente 6, 7 sind jeweils mit ihren ersten Seitenkanten 6a, 7a so mit dem Bodenelement 4c verbunden, dass der Grundkörper 4 im Wesentlichen die Form einer Rinne mit einem Hohlraum 8 bildet. Der Grundkörper 4 weist dabei einen U-förmigen Querschnitt auf. Wie später im Detail beschrieben, dient der Hohlraum 8 zur Aufnahme der Anschlussbuchsen 3. Der Grundkörper 4 erstreckt sich entlang der Richtung A bzw. B. An der zweiten Seitenkante 6b, 7b weist das erste und das zweite Seitenelement 6, 7 eine Anzahl an Aussparungen 9 auf. Wie in
Es ist dabei zu beachten, dass sich das Halteelement 10, welche dem ersten Ende 4a des Grundkörpers 4 am nächsten ist, in Richtung A erstreckt. Die übrigen Halteelemente 10 erstrecken sich in Richtung B.It should be noted here that the holding

Die erste Erhebung 11c ist außen, d.h. in Richtung C an der ersten Wandelement 11 positioniert und die zweite Erhebung 12c ist ebenfalls außen, d.h. in Richtung C' an der zweiten Wandelement 12 positioniert. Die beiden Erhebungen 11c, 12c dienen als Kontaktfläche der Anschlussbuchse 3 mit der Trägereinrichtung 2. Dadurch, dass die Wandelemente 11, 12 eine gewisse Vorspannung aufweisen, sind die Erhebungen 11c, 12c der Anschlussbuchsen 3 stets mit der Trägereinrichtung 2 zum Schliessen eines Stromkreises bzw. zur Übertragung eines elektrischen Stroms von dem Kontaktelement über die Anschlussbuchse 3 zu der Trägereinrichtung 2 verbunden.The
Die Ausnehmungen 11d, 12d an den jeweiligen Wandelementen 11, 12 sind im Wesentlichen rechteckig gestaltet und dienen dazu, die Halteelemente 10 aufzunehmen, sodass die Anschlussbuchsen 3 von den Halteelementen 10 in der Trägereinrichtung 2 positioniert und gehalten werden.The

Wie bereits vorstehend erwähnt, dient der Hohlraum 8 des Grundkörpers 4 der Trägereinrichtung 2 dazu, ein oder mehrere Anschlussbuchsen 3 aufzunehmen und zu halten. Das mit der Verbindungsvorrichtung 1 zu verbindende Kontaktelement wird stets mit allen Anschlussbuchsen 3 verbunden bzw. in alle Anschlussbuchsen 3 eingeführt, die sich auf der Trägereinrichtung 2 befinden. Die Anzahl der Anschlussbuchsen 3, die mit der Trägereinrichtung 2 verbunden werden und in die ein Kontaktelement eingeführt wird, hängt von der Leistungsfähigkeit des anzuschließenden Akkumulators bzw. von der maximalen Höhe der Stromstärke, die zwischen Verbindungsvorrichtung 1 und Kontaktelement fließen soll. Je mehr Anschlussbuchsen 3 an der Trägereinrichtung 2 positioniert sind desto höher kann die Stromstärke sein, die zwischen Verbindungsvorrichtung 1 und Kontaktelement fließen und desto größer kann die Leistungsfähigkeit des Akkumulators sein. Eine hohe Anzahl an Anschlussbuchsen 3 bietet eine größere Anschlussfläche für das Kontaktelement, sodass eine hohe Stromstärke unbedenklich bzw. ohne mögliche Beschädigung für die Verbindungsvorrichtung 1 fließen kann.As already mentioned above, the
Es ist hierbei zu beachten, dass es auch möglich ist, die Länge der Trägereinrichtung 2 entsprechend der Anzahl an Anschlussbuchsen 3 zu variieren. Somit kann eine kürzere Trägereinrichtung 2 (insbesondere ein kürzerer Grundkörper) verwendet werden, wenn weniger als fünf Anschlussbuchsen 3 auf der Trägereinrichtung 2 positioniert sind. Ebenso ist es auch möglich, dass die Trägereinrichtung 2 (bzw. der Grundkörper 4 der Trägereinrichtung 2) verlängert wird, wenn mehr als fünf Anschlussbuchsen 3 auf der Trägereinrichtung 2 positioniert werden sollen.It should be noted here that it is also possible to vary the length of the
Trägereinrichtung 2 in die jeweiligen Ausnehmungen 11d, 12d der Wandelemente 11, 12 der Anschlussbuchse 3 eingreifen. Hierdurch wird die Anschlussbuchse 3 in der Trägereinrichtung 2 positioniert und gehalten (vgl.
Die Anschlussbuchsen 3 gemäß der ersten Ausführungsform werden kraft- oder formschlüssig mit der Trägereinrichtung 2 gemäß der ersten Ausführungsform verbunden. Mit anderen Worten: die Anschlussbuchsen 3 werden zwischen die jeweiligen Halteelemente 10 eingeklemmt und von diesen in Position gehalten. Die Verbindung zwischen Anschlussbuchsen 3 und der Trägereinrichtung 2 gemäß der ersten Ausführungsform ist somit wieder lösbar.The
Im Vergleich dazu werden die Anschlussbuchsen 3 gemäß der zweiten Ausführungsform stoffschlüssig mit der Trägereinrichtung 2 gemäß der zweiten Ausführungsform verbunden. Zu den stoffschlüssigen Verbindungen zählen beispielsweise Schweißen, Löten, Kleben oder der gleiche.In comparison to this, the
Hierdurch wird folglich eine Verbindungsvorrichtung 1 zum lösbaren Verbinden von elektrischen Verbindungen, beispielsweise zwischen einem Akkumulator und einer elektrischen Werkzeugmaschine oder einem Akkumulator und einer Ladevorrichtung bereitzustellen, mit der insbesondere eine verbesserte, d.h. modular einsetzbar und in ihrer Herstellung flexiblere, Verbindungsvorrichtung 1 zur Verfügung gestellt wird.This consequently provides a
