Description
Die Erfindung betrifft eine elektrische Anschlusseinrichtung, insbesondere zur Übertragung von hohen Stromstärken, wie sie in unterschiedlichen technischen Bereichen erforderlich sind. Dabei werden beispielsweise Stromstärken von 125 Ampere und mehr bei Spannungen von bis zu 1000 Volt übertragen. Dazu können beispielsweise Leiter mit Querschnitten von 25 oder 35 mm2 erforderlich sein.The invention relates to an electrical connection device, in particular for the transmission of high currents, as required in different technical fields. In this case, for example, currents of 125 amperes and more are transmitted at voltages of up to 1000 volts. For this example, conductors with cross sections of 25 or 35 mm 2 may be required.
Im Stand der Technik sind verschiedene Anschlusseinrichtungen zur Übertragung von hohen Stromstärken bekannt geworden. Dazu zählen Flachsteckkontakte und insbesondere Rundsteckkontakte, bei denen die Kontaktstelle im Wesentlichen rotationssymmetrisch ausgebildet ist. Für derartig hohe Stromstärken werden meist Stecker mit gedrehten Anschlussteilen verwendet, um die auftretenden Stromstärken zuverlässig zu übertragen.Various connection devices for transmitting high currents have become known in the prior art. These include flat plug contacts and in particular circular plug contacts, in which the contact point is formed substantially rotationally symmetrical. For such high currents, plugs with twisted connection parts are usually used to reliably transmit the occurring current strengths.
Mit der
Bei den auf dem Markt erhältliche Rundsteckverbindern kann zwar der geforderte Strom übertragen werden, aber diese sind aufwändig in der Herstellung, was sich in relativ hohen Kosten niederschlägt. Außerdem weisen sie eine relativ große Bauform auf, was insbesondere bei mehrpoligen Anschlüssen unerwünscht ist.Although the required power can be transferred to the round connectors available on the market, these are expensive to produce, which translates into relatively high costs. In addition, they have a relatively large size, which is undesirable, especially in multi-pin connections.
Gemäß der
Aus der
Die
Vor dem Hintergrund des geschilderten Standes der Technik ist es deshalb die Aufgabe der vorliegenden Erfindung, eine elektrische Anschlusseinrichtung zur Verfügung zu stellen, welche zur Übertragung von hohen Stromstärken geeignet ist und bei welcher geringe Steck- und Ziehkräfte erforderlich sind, wobei die Stromübertragung auch dauerhaft zuverlässig funktioniert.Against the background of the described prior art, it is therefore an object of the present invention to provide an electrical connection device which is suitable for the transmission of high currents and in which low insertion and removal forces are required, the power transmission also permanently reliable works.
Diese Aufgabe wird gelöst durch eine elektrische Anschlusseinrichtung mit den Merkmalen des Anspruchs I. Bevorzugte Weiterbildungen der Erfindungen sind Gegenstand der Unteransprüche. Weitere vorteilhafte Merkmale und Ausgestaltungen der Erfindung werden in den Ausführungsbeispielen angegeben.This object is achieved by an electrical connection device with the features of claim I. Preferred developments of the invention are the subject of the dependent claims. Further advantageous features and embodiments of the invention are specified in the embodiments.
Die erfindungsgemäße elektrische Anschlusseinrichtung ist insbesondere zur Übertragung von hohen Stromstärken geeignet und umfasst wenigstens einen Flachkontakt mit einer Kontakttulpe und ein Kontaktmesser mit einer vorbestimmten Messerdicke, wobei der Flachkontakt zur Aufnahme des Kontaktmessers mit der vorbestimmten Messerdicke geeignet ist. Erfindungsgemäß wird eine zur Kontaktierung vorgesehene Kraft im Wesentlichen durch eine Überfeder in dem Kontaktbereich aufgebracht. Dabei weist die Kontakttulpe in einem unbelasteten Zustand etwa eine freie Eintrittsbreite auf, welche ungefähr der vorbestimmten Messerdicke des Kontaktmessers entspricht.The electrical connection device according to the invention is particularly suitable for transmitting high currents and comprises at least a flat contact with a contact tulip and a contact blade with a predetermined blade thickness, wherein the flat contact is suitable for receiving the contact blade with the predetermined blade thickness. According to the invention, a force provided for contacting is applied essentially by an over-spring in the contact region. In this case, the contact tulip in an unloaded state about a free entrance width, which corresponds approximately to the predetermined blade thickness of the contact blade.
Weiterhin ist erfindungsgemäß wenigstens eine Länge der Kontaktfinger der Kontakttulpe erheblich größer als eine entsprechende Länge der Überfederfinger der Überfeder. Insbesondere sind die schräg aufeinander zulaufenden Bereiche der Überfederfinger erheblich kürzer als die aufeinander zulaufenden Bereiche der Kontaktfinger. Erfindungsgemäß verlaufen die Überfederfinger erheblich schräger zu dem Aufnahmeraum mit einem aufgenommenen Kontaktmesser als die Kontaktfederfinger zu dem Aufnahmeraum oder dem Kontaktmesser. Dadurch wird erzielt, dass die Federkraft der Überfeder relativ groß ist, während durch die langen und relativ wenig geneigten Kontaktfederfinger eine geringe Federkonstante und eine große Kontaktfläche zur Verfügung gestellt wird. Die Kontaktkraft wird im Wesentlichen oder sogar nahezu vollständig durch die Überfeder aufgebracht.Furthermore, according to the invention, at least one length of the contact fingers of the contact tulip is considerably larger than a corresponding length of the over-spring fingers of the over-spring. In particular, the obliquely converging areas of the over-spring fingers are considerably shorter than the converging areas of the contact fingers. According to the invention, the over-spring fingers extend significantly obliquely to the receiving space with a recorded contact blade as the contact spring fingers to the receiving space or the contact blade. It is thereby achieved that the spring force of the over-spring is relatively large, while the long and relatively slightly inclined contact spring fingers a low spring constant and a large Contact area is provided. The contact force is applied substantially or even almost completely by the over-spring.
Die erfindungsgemäße elektrische Anschlusseinrichtung bietet erhebliche Vorteile. Durch den Einsatz der Überfeder können definierte Kontaktkräfte aufgebracht werden. Die erfindungsgemäße Lösung, bei der die Überfeder die Kontaktkraft genau in dem Kontaktbereich aufbringt, hat den erheblichen Vorteil, dass dadurch Setzungserscheinungen an der Kontakttulpe keine oder im Wesentlichen keine Rolle spielen.The electrical connection device according to the invention offers considerable advantages. By using the over-spring defined contact forces can be applied. The solution according to the invention, in which the over-spring applies the contact force precisely in the contact region, has the considerable advantage that settling phenomena on the contact tulip thereby play no or essentially no role.
Bei dem Stand der Technik gemäß der
Grundsätzlich spielt es erfindungsgemäß keine Rolle, ob durch die Kontakttulpe noch ein geringer Anteil der Kontaktkraft übertragen wird oder nicht, da jedenfalls der wesentliche Teil der Kontaktkraft durch die Überfeder in dem Kontaktbereich aufgebracht wird. Die Kontakttulpe weist im unbelasteten Zustand etwa eine freie Eintrittsbreite auf die ungefähr der Messerdicke des einzuführenden Kontaktmessers entspricht. Dadurch könnte ohne vorhandene Außenfeder das Kontaktmesser an sich ohne Kraftaufwand in die Kontakttulpe eingeschoben werden, allerdings wäre die Stromübertragung nicht gesichert. Zur Sicherung der für die Stromübertragung nötigen Kontaktkraft dient deshalb die Außenfeder, die den Kontaktbereich mit der vorgesehenen Kontaktkraft vorbelastet. Es herrschen definierte Bedingungen vor, die unabhängig von etwaigen Setzungsbedingungen an der Kontakttulpe dauerhaft aufrecht erhalten bleiben. Dadurch wird es ermöglicht, die tatsächliche Kontaktkraft zu verringern, wodurch ein höherer Bedienkomfort erreicht wird, wobei sowohI das
Aufstecken als auch das Abziehen eines Kontaktes erleichtert wird.In principle, it does not matter according to the invention whether a small proportion of the contact force is transmitted by the contact tulip or not, since at least the essential part of the contact force is applied by the over-spring in the contact area. In the unloaded state, the contact tulip has approximately a free entry width which corresponds approximately to the blade thickness of the contact blade to be inserted. As a result, the contact blade could be inserted without any external force into the contact tulip without any external spring, but the current transmission would not be ensured. To secure the necessary contact force for power transmission, therefore, the outer spring, which preloads the contact area with the intended contact force. Defined conditions prevail which are permanently maintained at the contact tulip independently of any possible settlement conditions. This makes it possible to reduce the actual contact force, whereby a higher ease of use is achieved, where sowohI
Plug on as well as the removal of a contact is facilitated.
Die Kontakttulpe weist insbesondere wenigstens zwei Kontaktarme auf, die im Kontaktbereich voneinander um die Eintrittsbreite beabstandet sind.The contact tulip has, in particular, at least two contact arms which are spaced apart from one another in the contact region around the entry width.
In einer erfindungsgemäßen Weiterbildung ist ein Durchsteckschutz vorgesehen, der insbesondere im hinteren Bereich der Kontakttulpe ein unabsichtliches Durchstecken verhindert.In an embodiment of the invention, a push-through protection is provided, which prevents unintentional insertion, in particular in the rear region of the contact tulip.
Der Durchsteckschutz kann dabei als ein die beiden Kontaktarme der Kontakttulpe verbindender Steg ausgeführt sein, sodass ein einfacher und effektiver Durchsteckschutz zur Verfügung gestellt wird.The push-through protection can be designed as a connecting the two contact arms of the contact tulip web, so that a simple and effective push-through protection is provided.
In einer bevorzugten Weiterbildung der Erfindung weisen die Überfeder und die Kontakttulpe jeweils eine Mehrzahl von Lamellen oder einander jeweils zugeordneten Kontaktfingerpaaren auf. Beispielsweise können drei, vier, fünf, sechs oder noch mehr Kontaktfingerpaare vorgesehen sein, die insgesamt die Kontakttulpe bzw. deren Kontaktarme bilden.In a preferred embodiment of the invention, the over-spring and the contact tulip each have a plurality of fins or mutually associated contact finger pairs. For example, three, four, five, six or even more pairs of contact fingers can be provided, which together form the contact tulip or its contact arms.
Vorzugsweise ist dann eine entsprechende Anzahl an Überfederfingerpaaren vorgesehen, wobei ein Überfederfingerpaar jeweils einem Kontaktfingerpaar zugeordnet ist. Insbesondere drückt jeweils ein Überfederfinger gegen einen Kontaktfinger der Kontakttulpe, sodass vorzugsweise jeder Kontaktfinger im Wesentlichen gleich belastet wird.Preferably, then a corresponding number of Überfederfingerpaaren is provided, wherein a Überfederfingerpaar is assigned in each case a pair of contact fingers. In particular, in each case an over-spring finger presses against a contact finger of the contact tulip, so that preferably each contact finger is loaded substantially equally.
In allen Ausgestaltungen ist die elektrische Anschlusseinrichtung insbesondere für Kontaktkräfte kleiner als 30 und insbesondere kleiner als 20 Newton ausgelegt. Vorzugsweise bringt jedes Kontaktfingerpaar Kontaktkräfte kleiner 7 und insbesondere kleiner 5 Newton auf In besonders bevorzugten Ausgestaltungen werden je Kontaktfingerpaar Kontaktkräfte zwischen etwa 3 und 4 Newton aufgebracht. Das ermöglicht einen hohen Bedienkomfort, da nur relativ geringe Steck- und Ziehkräfte bei der Herstellung oder Lösung eines elektrischen Kontakts mit einer elektrischen Anschlusseinrichtung erforderlich sind.In all embodiments, the electrical connection device is designed in particular for contact forces less than 30 and in particular less than 20 Newton. Preferably, each contact finger pair brings about contact forces of less than 7 and in particular less than 5 Newton. In particularly preferred embodiments, contact forces of between about 3 and 4 Newtons are applied per pair of contact fingers. This allows a high level of operating comfort, since only relatively small insertion and removal forces are required in the production or solution of an electrical contact with an electrical connection device.
Die genaue Anzahl der Kontaktfinger und der Überfinger und die jeweilige Kontaktkraft hängt insbesondere auch von der zu übertragenden Stromstärke ab.The exact number of contact fingers and the overfinger and the respective contact force also depends in particular on the current to be transmitted.
In bevorzugten Ausgestaltungen der erfindungsgemäßen elektrischen Anschlusseinrichtung weist wenigstens eine Kontaktfläche der Kontakttulpe eine Silber enthaltene Schicht auf. Schichten mit einem Silberanteil oder aus Silber können die Reibung erheblich verringern, sodass eine noch weitergehende Erhöhung des Komforts bei der Bedienung möglich ist. Ein weiterer Vorteil von Silber oder Silber enthaltenden Schichten ist die gute elektrische Leitfähigkeit.In preferred embodiments of the electrical connection device according to the invention, at least one contact surface of the contact tulip has a layer containing silver. Layers containing either silver or silver can significantly reduce friction, allowing for even greater comfort in operation. Another advantage of silver or silver containing layers is the good electrical conductivity.
In anderen Ausgestaltungen ist es auch möglich, mit Zinn versehene oder aus Zinn bestehende Schichten aufzubringen, um die Reibung zu verringern und um Korrosion zu verhindern.In other embodiments, it is also possible to apply tin or tin layers to reduce friction and prevent corrosion.
In allen Ausgestaltungen ist die erfindungsgemäße elektrische Anschlusseinrichtung insbesondere für die Übertragung von Stromstärken größer 80 Ampere geeignet. Vorzugsweise ist sie für eine Übertragung von Stromstärken größer 100 Ampere geeignet.In all embodiments, the electrical connection device according to the invention is particularly suitable for the transmission of currents greater than 80 amperes. Preferably, it is suitable for a transmission of currents greater than 100 amperes.
Vorteilhafterweise besteht die Kontakttulpe wenigstens teilweise aus Kupfermaterial und insbesondere aus einem Kupferflachbandmaterial, welches z.B. gestanzt ist und durch Umbiegen in die gewünschte Form gebracht wird.Advantageously, the contact tulip consists at least partially of copper material and in particular of a copper flat strip material, which is e.g. is punched and brought by bending into the desired shape.
Die Überfeder besteht vorzugsweise im Wesentlichen aus Stahlmaterial und kann ebenfalls aus einem Flachbandmaterial durch einen oder mehrere Biegevorgänge hergestellt sein. Dabei kann der Durchsteckschutz durch zwei aufeinandergebogene Bereiche gebildet werden.The over-spring preferably consists essentially of steel material and may also be made of a ribbon material by one or more bending operations. In this case, the push-through protection can be formed by two mutually bent regions.
Die erfindungsgemäße elektrische Anschlusseinrichtung kann sowohl an einer Grundleiste angeordnet sein als auch als Stecker ausgeführt sein. Auch eine fliegende Anordnung ist möglich.The electrical connection device according to the invention can be arranged both on a base strip as well as be designed as a plug.

Zwischen einem Kontaktfingerpaar mit zwei Kontaktfingern 15 ist im unbelasteten Zustand 8 eine definierte Eintrittsbreite 9 vorgesehen, die wenigstens im Wesentlichen der vorbestimmten Messerdicke 5 des Kontaktmessers 4 entspricht. Dadurch wird erreicht, dass nicht die Federarme 12 und 13 der Kontakttulpe 3 die erforderliche Klemmkraft aufbringen, sondern dass die erforderliche Kontaktkraft durch die Überfederfinger 17 der Überfeder 6 aufgebracht wird.Between a contact finger pair with two
Die Überfeder besteht vorzugsweise aus Stahl oder einem sonstigen ähnlich stabilen Material, während die Kontakttulpe mit den Kontaktfingerpaaren 11 vorteilhafterweise aus Kupfer oder eine Kupferlegierung bestehen.The over-spring is preferably made of steel or other similar stable material, while the contact tulip with the contact finger pairs 11 advantageously made of copper or a copper alloy.
Zur besseren Leitfähigkeit und zur Verringerung der Reibung können die Kontaktfinger 15 insgesamt oder an der Kontaktfläche 18 mit einer Silberbeschichtung oder eine silberhaltigen Beschichtung versehen sein. Dadurch wird eine Reibungsminderung erzielt, wodurch der Bedienkomfort durch geringere Steck- und Ziehkräfte erhöht wird.For better conductivity and to reduce the friction, the

Die nötige Kontaktkraft wird durch die Überfeder 6 aufgebracht, wozu die Überfederfinger 17 die Kontaktfingerpaare 11 in dem Kontaktbereich 7 mit einer definierten Federkraft belasten. Die Länge 16 der Überfederfinger 17 ist erheblich kürzer als die Länge 14 der Kontaktfinger 15. Dadurch wird erreicht, dass die Kontaktfinger 15 eine große Kontaktfläche 18 zur Verfügung stellen, während die Überfeder 6 eine relativ große Federkonstante aufweist, sodass die von der Überfeder 6 aufgebrachte Federkraft erheblich größer ist als eine eventuell an der Kontakttulpe 3 aufgebrachte Federkraft.The necessary contact force is applied by the
Die Überfeder 6 bringt die Kontaktkraft auf. Dadurch wird unter anderem bewirkt, dass eventuelle Setzungserscheinungen an den Federarmen 12 und 13 der Kontakttulpe 3 keinen oder nur einen sehr geringen Einfluss auf die Kontaktkraft haben, da diese im Wesentlichen oder ganz durch die Überfeder bestimmt wird. Deshalb weist die Kontakttulpe 3 in unbelasteten Zustand eine freie Öffnung auf, in die das Kontaktmesser 4 einschiebbar ist.The
Ein erheblicher Vorteil ist die Ausbildung der Federarme 12 und 13 mit mehreren Kontaktfederfingern 15, die lamellenartig an den Federarmen 12 und 13 vorgesehen sind. Hier im Ausführungsbeispiel sind insgesamt zehn Kontaktfederfinger 15 vorgesehen, die je insgesamt fünf Kontaktfederfingerpaare bilden.A significant advantage is the formation of the
Jedem Kontaktfinger 15 ist eine entsprechender Überfederfinger 17 zugeordnet, der den jeweiligen Kontaktfinger 15 mit einer definierten Kontaktkraft vorbelastet, um definierte Bedingungen beim Kontakt zu gewährleisten.Each
Sowohl die Überfeder 6 als auch die Kontakttulpe 3 sind vorzugsweise aus einstückigen Blechteilen durch Umbiegen hergestellt. Die Abwicklungen der gestanzten Blechteile sind in den
Die Überfeder 6 ist so aufgeführt, dass ein Federstahlflachband so ausgestanzt und gebogen wird, das ein geschlossener Käfig entsteht, der die elastische Seite des Tulpenkontakte völlig umschließt. Zudem sind entsprechend der Anzahl der Kontaktfederfinger 15 der Kontakttulpe 3 die Überfederfinger ausgeformt.The
Ein Durchsteckschutz 10 ist vorgesehen, der ein Durchstecken eines Leiters verhindert.A push-through
Die elektrische Anschlusseinrichtung 1 kann insbesondere auch in Flachstecksystemen mit mehrpoligen Steckverbindern eingesetzt werden. Die Erfindung erlaubt den Einsatz bei hohen Stromstärken bei einer gleichzeitig geringen Größe. So kann auch bei einem 10-poligen Stecker im Grundleistenaufbau eine sehr enge Teilung von z.B. 15 mm gewährleistet werden, wobei gleichzeitig die zur Bedienung nötigen Steck- und Ziehkräfte gering sind.The
Durch eine silberhaltige Oberfläche wird auch bei Vibrationen oder sich ständig ändernden Beanspruchungseinflüssen ein störungsfreier Betrieb gewährleistet.A silver-based surface ensures trouble-free operation even with vibrations or constantly changing stress influences.
Möglich ist sowohl eine fliegende Verbindung, bei der sowohl die Kontakttulpe als auch das Kontaktmesser im Stecker angeordnet ist, als auch die Verbindung des Kontaktmessers oder der Kontakttulpe mittels entsprechender Lötstifte in einer Grundleiste.It is possible both a flying connection, in which both the contact tulip and the contact blade is arranged in the plug, as well as the connection of the contact blade or the contact tulip by means of corresponding solder pins in a base bar.
Trotz geringer Klemmkräfte von insbesondere weniger als 4 Newton pro Kontaktpunkt wird die Übertragung hoher Ströme dauerhaft gewährleistet, während gleichzeitig der Bedienkomfort erhöht wird. Dies wird hier unter anderem dadurch erreicht, dass die Überfeder im Kontaktbereich die Kontaktkraft aufbringt. Gleichzeitig ist die erfindungsgemäße elektrische Anschlusseinrichtung 1 günstig zu fertigen.Despite low clamping forces of in particular less than 4 Newton per contact point, the transmission of high currents is permanently ensured, while at the same time the ease of use is increased. This is achieved, inter alia, by the fact that the over-spring in the contact area applies the contact force. At the same time, the
