Description
Die vorliegende Erfindung betrifft eine Steckkupplung zum elektrischen Kontaktieren eines von einer Handwerkzeugmaschine umfassten Elektromotors mit einer Akkueinheit. Die Akkueinheit ist von einer Handwerkzeugmaschine aufzunehmen. Die Steckkupplung weist wenigstens ein mit der Handwerkzeugmaschine zu verbindendes elektrisches Kontaktschwert und einen dazu korrespondierenden Kontaktstecker mit zwei einander gegenüberliegenden federnden Kontaktschenkeln auf. Der Kontaktstecker ist an der Akkueinheit anzuordnen und in Aufschubrichtung auf das Kontaktschwert aufzuschieben und in Abzugsrichtung von diesem abzuziehen. Jeder der federnden Kontaktschenkel weist einen Kontaktbereich auf, der in kontaktiertem Zustand eine jeweilige Seite des Kontaktschwerts elektrisch kontaktiert.The present invention relates to a plug-in coupling for electrically contacting an electric motor comprising a hand-held power tool with a battery unit. The battery unit is to be picked up by a hand tool. The plug-in coupling has at least one electric contact blade to be connected to the power tool and a corresponding contact plug with two opposing resilient contact legs. The contact plug is to be arranged on the battery unit and postponed in the direction of loading on the contact blade and deduct in the withdrawal direction of this. Each of the resilient contact legs has a contact region which electrically contacts a respective side of the contact blade in the contacted state.
Steckkupplungen der eingangs genannten Art sind grundsätzlich aus dem Stand der Technik bekannt.Plug-in couplings of the type mentioned are basically known from the prior art.
Es ist Aufgabe der vorliegenden Erfindung, eine Steckkupplung bereitzustellen, die eine stabile Stromübertragung unter applikationsbedingten Lasten wie beispielsweise Vibration begünstigt.It is an object of the present invention to provide a plug-in coupling, which favors a stable power transmission under application-related loads such as vibration.
Die Aufgabe wird dadurch gelöst, dass die Kontaktbereiche in unkontaktiertem Zustand, bezogen auf eine Auslenkrichtung der federnden Kontaktschenkel, voneinander beabstandet sind.The object is achieved in that the contact areas in the uncontacted state, based on a deflection of the resilient contact legs, are spaced from each other.
Durch diese Kontaktgestaltung können die resultierenden Steckkräfte beim Einsetzen einer Akkueinheit niedrig gehalten, und trotzdem in verbundenem Zustand ausreichend hohe Kontaktkräfte erzielt werden, die die gewünschte stabile Stromübertragung unter applikationsbedingten Lasten ermöglicht.Through this contact design, the resulting insertion forces can be kept low when inserting a battery unit, and yet sufficiently high contact forces can be achieved in the connected state, which allows the desired stable power transmission under application-related loads.
Die Erfindung schließt die Erkenntnis ein, dass die Stromtragfähigkeit einer Steckkupplung im realen Betrieb durch die technische Ausführung der Kontaktpaarung erhöht werden kann. Von besonderem Einfluss ist dabei die resultierende Kontaktnormalkraft in gestecktem (kontaktiertem) Zustand sowie die Materialstärke des Kontaktschwertes. Eine hohe Normalkraft sowie eine hohe Materialstärke des Kontaktschwertes führen jedoch, dies wurde als nachteilig erkannt, zu einer hohen Steckkraft, wenn die Akkueinheit in die Handwerkzeugmaschine eingesetzt wird.The invention includes the realization that the current carrying capacity of a plug-in coupling in real operation can be increased by the technical design of the contact pairing. Of particular influence is the resulting contact normal force in the plugged (contacted) state as well as the material thickness of the contact blade. However, a high normal force and a high material thickness of the contact blade lead, it was recognized as disadvantageous, to a high insertion force when the battery unit is inserted into the power tool.
Im Gegensatz zu aus dem Stand der Technik bekannten Steckkupplungen, beispielsweise aus der
In einer besonders bevorzugten Ausgestaltung ist vorgesehen, dass, in unkontaktiertem Zustand, ein parallel zur Auslenkrichtung der federnden Kontaktschenkel definierter Abstand der Kontaktbereiche zueinander, 10 bis 40 Prozent der Dicke des Kontaktschwerts beträgt. In diesem Bereich wurde, bei vergleichsweise niedrigen resultierenden Steckkräften, eine ausreichend hohe Kontaktkraft erzielt, die eine stabile Stromübertragung ermöglicht.In a particularly preferred embodiment, it is provided that, in the uncontacted state, a distance of the contact regions from one another parallel to the deflection direction of the resilient contact limbs amounts to 10 to 40 percent of the thickness of the contact blade. In this area, with sufficiently low resulting insertion forces, a sufficiently high contact force was achieved, which enables a stable power transmission.
Es hat sich als vorteilhaft herausgestellt, wenn, in unkontaktiertem Zustand, der definierte Abstand der Kontaktbereiche zueinander 0,3 Millimeter beträgt. Der definierte Abstand kann, in unkontaktiertem Zustand, zwischen 0,2 Millimeter und 0,4 Millimeter betragen. Das Kontaktschwert weist vorzugsweise eine Dicke zwischen 0,75 Millimeter und 3 Millimeter auf. Die Dicke des Kontaktschwerts ist parallel zur Auslenkrichtung der federnden Kontaktschenkel definiert.It has proven to be advantageous if, in the uncontacted state, the defined distance between the contact regions is 0.3 millimeters. The defined distance, in the uncontacted state, can be between 0.2 millimeters and 0.4 millimeters. The contact blade preferably has a thickness of between 0.75 millimeters and 3 millimeters. The thickness of the contact blade is defined parallel to the deflection of the resilient contact legs.
Es hat sich als vorteilhaft herausgestellt, wenn die Kontaktschenkel einen Fügewinkel aufweisen, der größer ist als ein Haltewinkel der Kontaktschenkel. Alternativ können Fügewinkel und Haltewinkel der Kontaktschenkel gleich sein.It has proven to be advantageous if the contact legs have a joining angle which is greater than a holding angle of the contact legs. Alternatively, joining angle and holding angle of the contact legs can be the same.
In einer weiteren bevorzugten Ausgestaltung weist jeder der Kontaktschenkel eine elastische Doppelzunge auf. Jede der Doppelzungen kann über zwei Zusatzfederelemente abgestützt sein, die einem Spreizen der zwei einander gegenüberliegenden elastischen Doppelzungen entgegenwirkt.In a further preferred embodiment, each of the contact legs on a resilient double tongue. Each of the double tongues can be supported by two additional spring elements, which counteracts a spreading of the two opposite elastic double tongues.
Im Sinne einer verbesserten Stromübertragung hat es sich als vorteilhaft herausgestellt, wenn die Kontaktbereiche linienförmig ausgebildet sind. Alternativ oder zusätzlich können sich die Kontaktbereiche sowohl senkrecht zur Aufschubrichtung als auch senkrecht zur Auslenkrichtung erstrecken.In terms of improved power transmission, it has proven to be advantageous if the contact areas are formed linear. Alternatively or additionally, the contact regions may extend both perpendicular to the push-on direction and perpendicular to the deflection direction.
Vorzugsweise weist die Steckkupplung zwei voneinander beabstandete Kontaktschwerter und/oder zwei voneinander beabstandete Kontaktstecker auf.Preferably, the plug-in coupling on two spaced contact blades and / or two spaced-apart contact plug.
Es hat sich als vorteilhaft herausgestellt, wenn der Kontaktstecker als Stanzteil bereitgestellt ist.It has proved to be advantageous if the contact plug is provided as a stamped part.
Die Erfindung wird ebenfalls gelöst durch eine Handwerkzeugmaschine mit einer vorbeschriebenen Steckkupplung, wobei das elektrische Kontaktschwert der Steckkupplung mit der Handwerkzeugmaschine verbunden ist und der Kontaktstecker an einer der Handwerkzeugmaschine zugeordneten Akkueinheit angeordnet ist.The invention is also achieved by a hand tool with a pre-described plug-in coupling, wherein the electrical contact blade of the plug-in coupling with the hand tool is connected and the contact plug is arranged on one of the hand tool machine associated battery unit.
