Here is a contact element with three tulips preferably made of three receiving tulle parts. However, it is also preferred an embodiment in which the receiving hood parts are connected to each other by tulip connectors. In this embodiment, for example, a contact element with three receiving tulips is made from two receiving tulle parts with a tulip connector, a contact element with five receiving tulips from three receiving tulle parts with two tulip connectors. For n recessed tulips, therefore, always n - 1 recessed hood parts and n - 2 tulip connectors are required. The tulip connectors are preferably also approximately U-shaped, but may be made of a less expensive material. In addition, an arbitrarily large contact element can be produced from such receiving tulip parts. In addition, the tulip connectors can also be used for joining a plurality of contact elements with a plurality of recessed tulips.
In einer bevorzugten Ausführungsform umfasst das Kontaktelement eine Überfeder, beispielsweise aus Stahl. Die Überfeder ist zur Ausübung einer Klemmkraft auf das Kontaktelement vorgesehen, die bevorzugt in und gegen eine Klemmrichtung wirkt. Die Klemmrichtung erstreckt sich bevorzugt quer zur ersten und/oder zweiten Richtung. Die Überfeder unterstützt daher das Kontaktelement beziehungsweise die auf ein Verbindungselement, das in dem Kontaktelement angeordnet ist, wirkende Rückstellkraft. Es ist bevorzugt, dass die Überfeder im Querschnitt etwa u- förmig ausgebildet ist.In a preferred embodiment, the contact element comprises an over-spring, for example made of steel. The over-spring is provided for exerting a clamping force on the contact element, which preferably acts in and against a clamping direction. The clamping direction preferably extends transversely to the first and / or second direction. The over-spring therefore supports the contact element or the restoring force acting on a connecting element which is arranged in the contact element. It is preferred that the over-spring in cross-section is approximately U-shaped.
Die Aufgabe wird weiterhin gelöst mit einer Steckanordnung mit einem Kontaktelement und zumindest einem elektrischen Verbindungselement, das zum elektrischen Verbinden des Kontaktelementes mit einer elektrischen Baugruppe vorgesehen ist. Ein solches elektrisches Verbindungselement ist beispielsweise ein Steckverbinder.The object is further achieved with a plug arrangement with a contact element and at least one electrical connection element which is provided for electrically connecting the contact element to an electrical assembly. Such an electrical connection element is for example a connector.
Vorzugsweise umfasst die Steckanordnung zudem zumindest zwei elektrische Verbindungselemente eines außen geführten Bussystems, insbesondere zwei Stromschienen. Die Stromschienen sind vorzugsweise fluchtend zueinander angeordnet und in derselben Aufnahmetulpe verklemmt. Bei dieser Anordnung sind die aus der ersten Richtung zugänglichen Aufnahmetulpen jeweils für eine Busleitung verwendbar. Dadurch sind zumindest zwei Busleitungen mit demselben Kontaktelement an die elektrische Baugruppe anschließbar. Oder ebenfalls bevorzugt sind die Stromschienen jeweils in eine Aufnahmetulpe des Kontaktelementes gefügt. Dadurch werden für dieselbe Busleitung zwar zwei Aufnahmetulpen benötigt. Aber die Kontaktfläche zu den Stromschienen ist größer, so dass sich die Anordnung besonders für Leistungsströme eignet.Preferably, the plug arrangement also comprises at least two electrical connection elements of an externally guided bus system, in particular two busbars. The busbars are preferably arranged in alignment with each other and jammed in the same receiving tulip. In this arrangement, the receiving tulips accessible from the first direction are each usable for a bus line. As a result, at least two bus lines with the same contact element to the electrical assembly can be connected. Or also preferred are the busbars each added to a receiving tulip of the contact element. This requires two recessed tulips for the same bus. But the contact surface with the busbars is larger, so that the arrangement is particularly suitable for power currents.
Die Steckanordnung umfasst bevorzugt ein Gehäuse, in dem das Kontaktelement angeordnet ist. Das Gehäuse ist vor allem als Berührschutz für einen Bediener vorgesehen.The plug arrangement preferably comprises a housing in which the contact element is arranged. The housing is intended primarily as a contact protection for an operator.
Die Aufgabe wird weiterhin gelöst mit einem elektrischen Gerät, insbesondere mit einem Reihenbaustein. Das elektrische Gerät umfasst bevorzugt eine elektrische Baugruppe sowie eine Steckanordnung, die zur elektrischen Verbindung der elektrischen Baugruppe mit dem außen geführten Bussystem vorgesehen ist, und die ein erfindungsgemäßes Kontaktelement umfasst.The object is further achieved with an electrical device, in particular with a series component. The electrical device preferably comprises an electrical assembly as well as a plug arrangement, which is provided for the electrical connection of the electrical assembly to the externally guided bus system, and which comprises a contact element according to the invention.
