Description

Die Erfindung geht aus von einer wiederlösbaren elektrischen Steckverbindung nach der Gattung des Anspruchs 1. Eine solche Steckverbindung ist aus der GB-A-1505207 bekannt. Hierin ist eine lösbare elektrische Steckverbindung offenbart, wobei ein Kontaktelement eine Leiterplatine mit einem Kontaktbereich umfasst. Ein anderes Steckelement umfasst ein Klemmelement. Dieses Klemmelement drückt das andere Steckelement zur Herstellung einer elektrischen Steckverbindung gegen den Kontaktbereich des Kontaktelements.The invention relates to a re-releasable electrical connector according to the preamble of claim 1. Such a connector is known from GB-A-1505207 known. Herein is disclosed a releasable electrical connector, wherein a contact element comprises a printed circuit board having a contact region. Another plug element comprises a clamping element. This clamping element presses the other plug-in element for producing an electrical plug connection against the contact region of the contact element.

Steckverbindungen sind in vielfältigen Ausführungen bekannt. Sie bestehen in der Regel aus einem Steckelement, beispielsweise einem Stecker, der in ein Gegensteckelement, beispielsweise eine Buchse einführbar ist, um eine wiederlösbare elektrische Steckverbindung einzugehen. Das Steckelement kontaktiert mit seinem Aussendurchmesser zumindest zum Teil in dem Innendurchmesser der Buchse des Gegensteckelements und führt so eine elektrische Kontaktierung herbei.Plug connections are known in many designs. They usually consist of a plug-in element, for example a plug, which can be inserted into a mating plug element, for example a socket, in order to enter into a redetachable electrical plug connection. The plug element contacted with its outer diameter at least partially in the inner diameter of the socket of the mating connector element, thus bringing about an electrical contact.

Andere Ausführungen von Gegensteckelementen weisen Leiterplatinen auf, die Kontaktbereiche umfassen, in die Steckelemente einführbar sind. In der Regel handelt es sich bei diesen Kontaktbereichen um Buchsen, die unmittelbar auf der Leiterplatine angeordnet sind.Other versions of mating plug-in elements have printed circuit boards which comprise contact regions into which plug-in elements can be inserted. As a rule, these contact areas are sockets which are arranged directly on the printed circuit board.

Ein Nachteil der vorstehenden Ausführung des Standes der Technik besteht darin, dass es sich dabei um keine zuverlässige elektrische Verbindungen handelt, die insbesondere einer Reibkorrosion widersteht. Durch Mikrobewegungen in den Kontaktstellen durch die Kontaktpartnern und durch hohe Steckkräfte, die notwendig sind, um ein ungewolltes Lösen zu verhindern, entsteht insbesondere bei mehrpoligen Steckverbindungen diese Art von Korrosion, die sich auf die Qualität der elektrischen Steckverbindung negativ auswirkt.A disadvantage of the above embodiment of the prior art is that it is not a reliable electrical connections, which in particular resists fretting corrosion. By micro-movements in the contact points by the contact partners and high insertion forces, which are necessary to prevent unwanted loosening, arises in particular in multi-pin connectors this type of corrosion, which has a negative effect on the quality of the electrical connector.

Des weiteren sind nur technisch aufwendige und teure Lösungen für Kontakte bekannt, die hohe technische Anforderungen, wie beispielsweise Stromübertragung, Steckzyklen, Schütteln etc. erfüllen.Furthermore, only technically complex and expensive solutions for contacts are known that meet high technical requirements, such as power transmission, mating cycles, shaking, etc.

Die Aufgabe der Erfindung besteht darin, eine zuverlässige elektrische und wiederlösbare Steckverbindung kostengünstig auszubilden.The object of the invention is to design a reliable electrical and re-releasable connector inexpensively.

Diese Aufgabe wird, ausgehend von einer wiederlösbaren elektrischen Steckverbindung entsprechend den gattungsgemäßen Merkmalen des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Bei dieser Anordnung ist ein Steckelement mit einer Hülse versehen, die bei hergestellter Steckverbindung mit dem Kontaktbereich eines Gegensteckers kontaktiert.This object is achieved on the basis of a re-releasable electrical connector according to the generic features of claim 1 by the characterizing features of claim 1. In this arrangement, a plug-in element is provided with a sleeve which makes contact with manufactured contact with the contact area of a mating connector.

Dadurch ergibt sich der Vorteil, dass die vorgeschlagene Steckverbindung sehr platzsparend aufgebaut ist. Zudem ist die Steckverbindung auch unter ungünstigen Betriebsbedingungen funktionssicher.This results in the advantage that the proposed connector is constructed very space-saving. In addition, the connector is reliable even under unfavorable operating conditions.

Ferner erweist es sich von Vorteil, dass die an sich üblichen Pins bzw. Messerleisten einer elektrischen Steckverbindung nicht mehr notwendig sind. Dadurch können Pins bzw. Messerleisten eingespart werden.Furthermore, it proves to be advantageous that the per se conventional pins or male connectors of an electrical connector are no longer necessary. As a result, pins or male connectors can be saved.

Zudem lässt sich diese Art der Ausführung einer elektrischen Steckverbindung sehr einfach in Sensoren, Ventilen oder ähnlichen Komponenten einsetzen, in denen eine lösbare elektrische Steckverbindung zu realisieren ist, aber der notwendige Bauraum dafür stark eingeschränkt ist.In addition, this type of execution of an electrical connector very easy to use in sensors, valves or similar components in which a releasable electrical connector is to be realized, but the space required for it is severely limited.

Weitere vorteilhafte Ausgestaltungen gehen aus der nachfolgenden Beschreibung sowie den Unteransprüchen hervor.Further advantageous embodiments will become apparent from the following description and the appended claims.

Beschreibung der AusführungsbeispieleDescription of the embodiments

In Fig.1 ist ein Gegenstecker 1 im Schnitt dargestellt. Er besteht aus einem Gehäuse 2 sowie ein in dem Gehäuse 2 gelagerten Kontaktelement 3, wobei das Kontaktelement 3 bei diesem Ausführungsbeispiel eine Leiterplatine umfasst.In Fig.1 is a mating connector 1 shown in section. It consists of a housing 2 and a mounted in the housing 2 contact element 3, wherein the contact element 3 comprises a printed circuit board in this embodiment.

Ein Stecker 12 besteht aus einem Kontaktträger 11, Steckelementen 6 und Klemmelementen 4, welche zu beiden Seiten der Steckelemente 6 angeordnet sind. Der Kontaktträger 11 weist zusätzliche Öffnungen 5 auf, durch die die Steckelemente 6 einführbar sind. Der Stecker 12 kann eine Vielzahl der hier dargestellten Steckelemente 6 umfassen (Vielpolstecker).A plug 12 consists of a contact carrier 11, plug-in elements 6 and clamping elements 4, which are arranged on both sides of the plug-in elements 6. The contact carrier 11 has additional openings 5, through which the plug-in elements 6 can be inserted. The plug 12 may include a plurality of plug-in elements 6 shown here (multi-pin plug).

In Kontaktstellung, wie sie in der Fg.1 dargestellt ist, enden die Steckelemente 6 in einem Kontaktbereich 7 des Kontaktelements 3. Die einen Enden der Steckelemente 6 sind derart ausgestaltet, dass diese zu beiden Seiten des Kontaktelements 3 in dessen Längserstreckung anliegen und so eine elektrische Verbindung zwischen den Steckelementen 6 und dem Kontaktelement 3 des Gegensteckerelements 1 herstellen.In the contact position, as shown in Fg.1, the plug-in elements 6 end in a contact region 7 of the contact element 3. The one ends of the plug-in elements 6 are designed such that they rest on both sides of the contact element 3 in its longitudinal extent and so on produce electrical connection between the plug-in elements 6 and the contact element 3 of the mating connector element 1.

Zur Fixierung der Steckelemente 6 an dem Kontaktelement 3 sind die Klemmelemente 4 des Kontaktträgers 11 vorgesehen, die bei dem hier dargestellten Ausführungsbeispiel die einen Enden der Steckelemente 6 zumindest zum Teil umgreifen und die einen Enden der Steckelemente 6 gegen die Kontaktbereiche 7 des Kontaktelements 3 drücken.For fixing the plug-in elements 6 to the contact element 3, the clamping elements 4 of the contact carrier 11 are provided, which surround at least partially in the embodiment shown here one end of the plug elements 6 and press one end of the plug-in elements 6 against the contact areas 7 of the contact element 3.

Die Klemmwirkung der Klemmelemente 4 kann auf unterschiedliche Weise hergestellt werden:The clamping action of the clamping elements 4 can be produced in different ways:

Zum einen besteht die Möglichkeit, dass es sich bei den Klemmelementen 4 um verschieblich gelagerte Elemente handelt, die entweder durch Fügen des Kontaktträgers 11 oder durch Stellelemente, die in den Zeichnungen nicht näher dargestellt sind, ein Fixieren der Steckelemente 6 bewirken.On the one hand, there is the possibility that the clamping elements 4 are displaceably mounted elements which cause fixing of the plug-in elements 6 either by joining the contact carrier 11 or by adjusting elements which are not shown in detail in the drawings.

Zum anderen besteht die Möglichkeit, dass die Klemmelemente 4 Rastelemente aufweisen, in denen die Steckelemente 6 in ihrer Kontaktstellung, wie in der Figur 1 dargestellt, verrasten.On the other hand, there is the possibility that the clamping elements 4 have latching elements in which the plug-in elements 6 in their contact position, as in the FIG. 1 shown, lock.

Um eine optimierte Kontaktmöglichkeit zwischen dem Kontaktelement 3 und den Steckelementen 6 zu schaffen, ist vorgesehen, die Steckelemente 6 mit je einer Hülse 8, wie sie in Fig. 2 dargestellt ist, zu versehen. Diese Hülsen 8 bestehen aus einem elektrisch leitenden Material, das über Kontaktstücke der Steckelemente 6 geschoben wird.In order to provide an optimized contact possibility between the contact element 3 and the plug-in elements 6, it is provided that the plug-in elements 6, each with a sleeve 8, as in Fig. 2 is shown to be provided. These sleeves 8 are made of an electrically conductive material which is pushed over contact pieces of the plug-in elements 6.

Auf dem Aussenumfang 9 der Hülsen 8 sind Wülste 10 vorgesehen, die definierte Kontaktpunkte mit dem Kontaktelement 3 im Kontaktbereich 7 schaffen. Die Hülsen 8 sind über zumindest zum Teil abisolierte Enden eines Kabels elektrisch leitend fixierbar, so dass auf einfache Art und Weise diese Steckelemente 6 geschaffen werden können.On the outer circumference 9 of the sleeves 8 beads 10 are provided which create defined contact points with the contact element 3 in the contact area 7. The sleeves 8 are electrically conductively fixed on at least partially stripped ends of a cable, so that these plug-in elements 6 can be created in a simple manner.

Dies eröffnet die Möglichkeit, auf Messer im Gegenstecker 1 und Pins im Stecker 12 zu verzichten und aufwendige Verbindungsverfahren zwischen Messer bzw. Pins einzusparen.This opens up the possibility to dispense with knives in the mating connector 1 and pins in the connector 12 and save costly connection procedures between knives or pins.
