Description

Die Erfindung betrifft eine Kontaktelementgruppe nach dem Oberbegriff des unabhängigen Anspruches.The invention relates to a contact element group according to the Preamble of the independent claim.

Eine derartige Kontaktelementgruppe ist u.a. ein sogenannter Doppelflachstecker. Das sind zwei Flachstecker, die an ihren rückseitigen Stirnseiten miteinander verbunden sind, wobei der Verbindungsbereich den Basisbereich darstellt. Im Basisbereich befindet sich in der Regel eine zentrale Bohrung, über die die meist nicht isolierte Kontaktelementgruppe mit einer Schraube oder einem Niet beispielsweise an einer Gerätegehäuserückwand oder einem internen Gehäusevorsprung befestigt wird, Teilweise sind die Kontanktelementgruppen gebogen ausgeführt, so daß jedes Kontaktelement bzw. jede Steckfahne des einzelnen Flachsteckers unter einem Winkel von 15-90° vom Basisbereich absteht. Die Kontaktelementgruppen, die ggf. auch mehrfach übereinander montiert werden, bilden eine Art Sammelschiene oder Mehrfachverteiler, beispielsweise für mehrere Schutzleiter einzelner elektrischer Gerätebaugruppen. Solche Verteiler benötigen viel Platz, da die einzelnen Anschlüsse sternförmig vom Basisbereich abstehen. Aus diesem Grund ist es selten möglich, die Gegenkontaktelemente der anzuschließenden Leiter maschinell zu montieren. Such a contact element group is i.a. a so-called Double tab. These are two tabs on their back end faces are interconnected, the Connection area represents the base area. In the base area there is usually a central hole through which the usually not insulated contact element group with a screw or a rivet, for example on a rear wall of the device housing or an internal ledge is partially attached the contact element groups are curved, so that each Contact element or each tab of the individual tab connector protrudes from the base area at an angle of 15-90 °. The contact element groups, which may also be repeated one above the other assembled, form a kind of busbar or Multiple distributors, for example for several protective conductors individual electrical device assemblies. Such distributors need lots of space because the individual connections are star-shaped stand out from the base area. Because of this, it is rarely possible the mating contact elements of the conductors to be connected mechanically to assemble.

Ferner ist auch ein Isoliergehäuse zum Umgeben eines so sperrigen Mehrfachverteilers kompliziert und materialaufwendig.Furthermore, an insulating housing for surrounding such a bulky one Multiple distributor complicated and material-intensive.

Aus der US PS 3 694 564 (Edward Henry Pater), D1, ist eine elektrische Anschlußanordnung mit einem leitenden Teil bekannt, an welchem ein abisolierter Bereich eines Leiters an einer Stelle festgecrimpt wird. Die gecrimpten Arme, die um den abisolierten Leiterbereich greifen, sind einstückig mit Anschlußklingen geformt. Der so gebildete Anschluß wird in einem Gehäuse mittels Vorsprüngen fixiert, die am Gehäuse angeformt sind, um eine relative Bewegung zwischen dem Verbinder und dem Gehäuse zu minimieren.From US Pat. No. 3,694,564 (Edward Henry Pater), D1, is one known electrical connection arrangement with a conductive part, to which an stripped area of a conductor is attached is crimped in place. The crimped arms around gripping the stripped conductor area are integral with Connection blades shaped. The connection thus formed is in one Housing fixed by means of projections, which are molded onto the housing are a relative movement between the connector and minimize the housing.

Es besteht allgemein Bedarf nach einer Kontaktelementgruppe einer elektrotechnischen Mehrfachsteckverbindung, die auf kleinem Raum mehrere, verschiedenartige lösbare und nicht lösbare Anschlußmöglichkeiten bietet. Ferner soll sie problemlos in ein Isoliergehäuse eingebaut bzw. eingesetzt werden können. Ausgehend von diesem Bedarf besteht die Aufgabe der vorliegenden Erfindung darin, Neues für gewerbliche Anwendung bereitzustellen und insbesondere, jedoch nicht ausschließlich einen Austausch beschädigter Kabel, insbesondere Netzkabel und dergleichen zu vereinfachen. There is a general need for a contact element group an electrotechnical multiple connector, which small space several, different types of detachable and non-detachable Offers connectivity. Furthermore, it should be easy can be installed or used in an insulating housing. Based on this need, there is the task of the present Invention in providing new for commercial use and especially, but not exclusively, one Replacement of damaged cables, especially power cables and the like to simplify.

Das Problem wird mit Hilfe einer Kontaktelementgruppe mit den Merkmalen des Hauptanspruchs gelöst. Durch die am Basisbereich angeordnete Crimphülse kann die Kontaktelementgruppe platzsparend und unlösbar mit einem Leiter verbunden werden. Dieser Leiter kann Teil eines Geräteanschluß bzw. eines Netzkabels sein, das in das Gehäuse des entsprechenden Gerätes hineingeführt wird, um dort einzelne elektrische Gerätebaugruppen mit jeweils einem Leiter, z.B. entweder einem Schutzleiter, oder einem Neutralleiter oder einem anderen stromführenden Leiter anschließen zu können. Es wird hierbei weiter im Basisbereich ein Gewinde für eine Schraubklemmverbindung vorgesehen, so daß mindestens ein Leiter direkt, also ohne Gegenkontaktelement, an der Kontaktelementgruppe festgeklemmt werden kann. Die Schraubklemmverbindung erweist sich u.a. beim Austausch eines beschädigten Gerätenetzkabels als vorteilhaft. Die blanken Leiter des neuen Netzkabels können direkt an den Schraubklemmverbindungen angeklemmt werden, also ohne Austausch der Kontaktelementgruppen.The problem is solved using a contact element group with the Features of the main claim solved. By at the base area arranged crimp sleeve can the contact element group space-saving and permanent connection to a conductor. This conductor can be part of a device connection or a power cable be in the housing of the corresponding device is introduced to there individual electrical device assemblies with one conductor each, e.g. either a protective conductor, or a neutral conductor or another live conductor To be able to connect conductors. It will continue here in the base area a thread for a screw clamp connection provided so that at least one conductor directly, that is without Mating contact element, on the contact element group can be clamped. The screw clamp connection proves among other things when replacing a damaged device power cord as beneficial. The bare conductors of the new power cord can be clamped directly to the screw terminals, without exchanging the contact element groups.

Der Basisbereich besteht bevorzugt aus einem Boden mit zwei daran beidseitig angeordneten, parallelen Seitenstegen. Vom Boden und zumindest von einem Seitensteg aus zweigt jeweils mindestens ein Kontaktelement ab. Die Kontaktelemente haben die gleiche Bauform, beispielsweise genormte Flachstecker oder Steckhülsen, und weisen in die gleiche Richtung.The base area preferably consists of a floor with two parallel side bars arranged on both sides. from Bottom and branches off at least from one side bridge at least one contact element. The contact elements have the same design, for example standardized flat plugs or sockets, and point in the same direction.

Die Crimphülse ist beispielsweise am Boden oder einem Seitensteg angeordnet. Sie liegt dabei auf der einen Seite des Basisbereichs, während die gleichartigen Kontaktelemente auf der anderen Seite liegen. Vorzugsweise ist die Crimphülse in der Verlängerung eines Flachsteckers oder einer Steckhülse angeordnet. Auf diese Weise sind die lösbaren und die nicht lösbaren Kontaktelemente raumsparend hintereinander angeordnet, so daß beispielsweise ein Gerätenetzkabel mit den angecrimpten Kontaktelementgruppen durch eine kleine Gerätegehäusebohrung durchgeführt werden kann.The crimp sleeve is, for example, on the floor or a side bar arranged. It lies on one side of the Base area while the like contact elements on the other side. The crimp sleeve is preferably in the extension of a flat plug or a receptacle arranged. In this way, the detachable ones and the none are detachable contact elements arranged one behind the other to save space, so that, for example, a device power cord with the crimped on Contact element groups through a small device housing hole can be carried out.

Die Crimphülse kann auch um eine Isolierumfassung verlängert sein. Außerdem können am Basisbereich auch mehrere Crimphülsen angeordnet sein.The crimp sleeve can also be extended by an insulating enclosure his. In addition, several crimp sleeves can be used at the base area be arranged.
