Description

Elektrische Steckverbindung Electrical connector
Die Erfindung betrifft eine elektrische Steckverbin- düng mit wenigstens zwei an einem elektrischen Bauteil, beispielsweise einem Magnetventil, einem Druckregler oder ähnlichem, vorgesehenen Rundkontakten. Dabei enthält ein Rundkontakt, vorzugsweise der innere, ein Justiermittel . Zur Verbindung der Rundkontakte mit einem weiteren elektri- sehen Bauteil ist ein Stecker mit wenigstens zwei Steckkontakten vorgesehen.The invention relates to an electrical plug-in connection with at least two round contacts provided on an electrical component, for example a solenoid valve, a pressure regulator or the like. A round contact, preferably the inner one, contains an adjusting means. A connector with at least two plug contacts is provided for connecting the round contacts to a further electrical component.
Steckverbindungen der vorgenannten Art sind aus dem Stand der Technik hinreichend bekannt. Bei derartigen Steckverbindungen ist es von Nachteil, daß für die Montage des Steckers dieser zu dem elektrischen Bauteil in einer vorgegebenen Lage ausgerichtet werden muß, damit die Kon- taktierung und die Arretierung des Steckers an dem Bauteil erfolgt. Da ferner bei aktuatorischen Elementen, wie bei- spielsweise einem Druckregler, meist eine Justierung erforderlich ist und das Justiermittel üblicherweise zentrisch an einer Stirnseite des Bauteils angeordnet ist, auf welche auch der Stecker aufsteckbar ist, muß die Justierung zwangsläufig vor dem Aufstecken des Steckers auf die Kon- takte erfolgen.Plug connections of the aforementioned type are sufficiently known from the prior art. With plug connections of this type, it is disadvantageous that the plug must be aligned with the electrical component in a predetermined position in order for the plug to be contacted and locked on the component. Furthermore, since adjustment is usually required in the case of actuator elements, such as a pressure regulator, and the adjustment means is usually arranged centrally on an end face of the component, to which the plug can also be plugged, the adjustment must inevitably take place before the plug is plugged on Contacts are made.
Aufgabe der vorliegenden Erfindung ist es daher, eine elektrische Steckverbindung für elektrische Bauteile anzugeben, welche zum einen eine konstruktiv vorgegebene Aus- richtung des einzelnen Steckers zu den Kontakten nicht erforderlich macht und zum anderen auch nach dem Aufsetzen des Steckers auf die Kontakte einen freien Zugang des Justiermittels ermöglicht. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Steckverbindung Mittel aufweist, welche so ausgebildet sind, daß der Stecker in einer Ebene, welche sich beispielsweise senkrecht zur Längsachse der Rundkontakte er- streckt, aus beliebiger Richtung auf die Rundkontakte aufsteckbar und an diesen und/oder dem elektrisch-en Bauteil arretierbar ist und daß das Justiermittel frei zugänglich ist. Vorteilhafterweise ist somit der Stecker wenigstens in einer Ebene richtungsunabhängig auf die Rundkontakte auf- steckbar und auch ebenfalls unabhängig von der Aufsteckrichtung an den Rundkontakten selbst und/oder an dem elektrischen Bauteil arretierbar. Die Steckverbindung, insbesondere der Stecker, ist ferner derart ausgebildet, daß das Justiermittel vorteilhafterweise auch nach dem Aufsetzen des Steckers auf die Kontakte frei zugänglich ist.It is therefore an object of the present invention to provide an electrical plug connection for electrical components which, on the one hand, does not require a structurally predetermined alignment of the individual plug to the contacts and, on the other hand, also provides free access for the plug after the plug has been placed on the contacts Adjustment means enabled. This object is achieved according to the invention in that the plug connection has means which are designed such that the plug can be plugged onto the round contacts from any direction and onto these and / or in a plane which extends, for example, perpendicular to the longitudinal axis of the round contacts the electrical component can be locked and that the adjusting means is freely accessible. Advantageously, the plug can thus be plugged onto the round contacts at least in one direction, regardless of direction, and can also be locked onto the round contacts themselves and / or on the electrical component, regardless of the plugging direction. The plug connection, in particular the plug, is also designed such that the adjusting means is advantageously freely accessible even after the plug has been placed on the contacts.
In einer Weiterbildung der Erfindung weist der Stecker mindestens zwei übereinander angeordnete, als U-förmige Federlaschen ausgebildete Steckkontakte auf, deren Öffnun- gen in dieselbe Richtung weisen. Dadurch wird vorteilhafterweise ermöglicht, daß der Stecker einfach und sicher gleichzeitig auf beide Rundkontakte aufsteckbar ist und daß zwischen den beiden Steckkontakten ein Isolator zur Trennung der beiden Rundkontakte vorgesehen werden kann.In a further development of the invention, the plug has at least two plug contacts arranged one above the other, designed as U-shaped spring tabs, the openings of which point in the same direction. This advantageously enables the plug to be plugged onto both round contacts simply and securely at the same time and that an isolator can be provided between the two plug contacts for separating the two round contacts.
Vorteilhafterweise weist der Stecker und/oder die Rundkontakte und/oder das Bauteil selbst wenigstens einen Rasthaken und eine Rastkerbe zur axialen und/oder radialen Arretierung des Steckers an den Rundkontakten auf, wobei die Angabe axial und radial auf die Längsachse der Rundkontakte bezogen ist. In einer bevorzugten Ausbildungsform wird vorgeschlagen, konzentrisch zur Längsachse der Rundkontakte einen Zahnkranz vorzusehen, welcher radial nach außen geöffnete Rastkerben aufweist, in die wiederum wenigstens eine an einem weiteren Bauteil angebrachte Rastnase zur Arretierung des Steckers in Urαfangsrichtung eingreift. Durch die erfindungsgemäßen Rastmittel, wie den Zahnkranz mit Rastkerben und die korrespondierende Rastnase, wird vorteilhafterweise eine Ausbildung vorgeschlagen, welche in einer definierten Ebene ein Aufstecken und Arretieren des Steckers aus nahezu jeder Richtung ermöglicht, da die Rastnase in ede beliebige der am Umfang des Zahnkranzes vorgesehenen Rastkerben einrastbar ist.Advantageously, the plug and / or the round contacts and / or the component itself has at least one latching hook and a latching notch for axially and / or radially locking the plug on the round contacts, the information relating axially and radially to the longitudinal axis of the round contacts. In a preferred embodiment, it is proposed to provide a toothed ring concentric to the longitudinal axis of the round contacts, which has radially outwardly open notches, in which at least one latching lug attached to a further component engages in order to lock the plug in the original direction. Due to the locking means according to the invention, such as the ring gear with locking notches and the corresponding locking lug, an embodiment is advantageously proposed which enables the plug to be plugged in and locked from almost any direction in a defined plane, since the locking lug is provided in any of the provided on the circumference of the ring gear Notches can be snapped into place.
Vorteilhafterweise ist der Zahnkranz direkt an dem elektrischen Bauteil und die korrespondierende Rastnase an dem Stecker vorgesehen. Dadurch wird eine Lösung vorgeschlagen, welche mit einfachen Mitteln eine Sicherung des Steckers in Umfangsrichtung an dem Bauteil ermöglicht, ohne daß der Stecker in einer bestimmten Richtung auf die Kontakte aufgesteckt zu werden braucht.The gear rim is advantageously provided directly on the electrical component and the corresponding latching lug on the plug. This proposes a solution which enables simple securing of the plug in the circumferential direction on the component without the plug needing to be plugged onto the contacts in a certain direction.
In einer anderen Weiterbildung wird vorgeschlagen, daß der Stecker den Zahnkranz zumindest bereichsweise auf sei- ner Ober- und/oder Unterseite umgreift. Dies kann beispielsweise mittels einer Auflagefläche und eines Rasthakens an dem Stecker erfolgen. Damit wird vorteilhafterweise eine einfache Arretierung des Steckers in axialer Richtung bezüglich der Längsachse der Kontakte bzw. der Längsachse des Druckreglers ermöglicht.In another development, it is proposed that the plug encompasses the toothed ring at least in regions on its top and / or bottom. This can be done for example by means of a support surface and a locking hook on the connector. This advantageously enables simple locking of the plug in the axial direction with respect to the longitudinal axis of the contacts or the longitudinal axis of the pressure regulator.
Zur Sicherung des Steckers an dem elektrischen Bauteil in radialer Richtung wird beispielsweise ein Rasthaken vor- geschlagen, welcher an dem Stecker federnd gelagert ist. Dieser Rasthaken ist mit der Stirnseite des inneren Rundkontaktes verrastbar, indem der Stecker in einer Ebene senkrecht zur Längsachse des Kontaktes auf diesen aufge- schoben wird.To secure the plug on the electrical component in the radial direction, a locking hook is provided, for example. struck, which is resiliently mounted on the plug. This latching hook can be latched to the end face of the inner circular contact by pushing the plug onto the contact in a plane perpendicular to the longitudinal axis of the contact.
Der Rasthaken weist ferner eine Ausnehmung auf, die so ausgebildet und angeordnet ist, daß das Justiermittel, beispielsweise eine Stellschraube, welche sich in dem Inneren des Rundkontaktes befindet, bei aufgeschobenem Stecker von der Stirnseite des Rundkontaktes frei zugänglich ist. Diese Ausnehmung kann vorteilhafterweise als Bohrung ausgebildet sein, durch die der Kopf der Stellschraube auch nach dem Aufsetzen des Steckers gut erreichbar ist.The latching hook also has a recess which is designed and arranged such that the adjusting means, for example an adjusting screw, which is located in the interior of the round contact, is freely accessible from the end face of the round contact when the plug is pushed on. This recess can advantageously be designed as a bore through which the head of the set screw can be easily reached even after the plug has been put on.
In einer Weiterbildung der Erfindung wird vorgeschlagen, die elektrische Steckverbindung in modularer Bauweise auszuführen, wobei mehrere elektrische Bauteile, beispielsweise mehrere Druckregler, eine Kontaktleiste bilden, wel- ehe mit einer mehrere Stecker aufweisenden Steckerleiste verbindbar ist. Durch eine derartige Ausbildung wird vorteilhafterweise eine schnelle und einfache Montage der Stecker an den elektrischen Bauteilen ermöglicht. Dabei sind mehrere elektrische Bauteile, beispielsweise Druckreg- 1er, in einem gemeinsamen Gehäuse äquidistant nebeneinander angeordnet, wobei die Rastnasen an dem Stecker bzw. der Steckerleiste zur Arretierung der einzelnen Stecker in Um- fangsrichtung vorteilhafterweise entfallen, da sich die Steckerleiste an der Kontaktleiste abstützt und somit be- reits eine Arretierung der Einzelstecker in Umfangsrichtung erfolgt . Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung der Ausführungsbeispiele, die in den Zeichnungen näher dargestellt sind. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger sinnvoller Kombination den Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Ansprüchen und deren Rückbeziehung. Es zeigen:In a development of the invention, it is proposed to carry out the electrical plug connection in a modular design, with several electrical components, for example several pressure regulators, forming a contact strip, which can be connected to a plug strip having a plurality of plugs. Such a design advantageously enables quick and easy assembly of the plug on the electrical components. In this case, several electrical components, for example pressure regulators, are arranged equidistantly next to one another in a common housing, the latching lugs on the connector or the connector strip for locking the individual connectors in the circumferential direction advantageously being omitted, since the connector strip is supported on the contact strip and the individual plugs are thus already locked in the circumferential direction.

Die U-förmige Ausnehmung des Kontakts 26 ist derart bemessen, daß der äußere Steckkontakt 26 den äußeren Rundkontakt 13 an dem Druckregler 10 gerade umgreift und klemmt.The plug 17 (FIG. 5) contains a U-shaped outer plug contact 26, which has two spring arms and is surrounded by a plug housing 27. The U-shaped recess of the contact 26 is dimensioned such that the outer plug contact 26 just engages around the outer round contact 13 on the pressure regulator 10 and clamps it.
Der innere Steckkontakt 25 (Fig. 6) ist ebenfalls als U-förmiger Steckkontakt ausgebildet, wobei dessen Ausneh- mung gerade so ausgebildet ist, daß der innere Steckkontakt 25 den inneren Rundkontakt 12 umfaßt und klemmt. Der innere Rundkontakt 12 enthält eine an ihrem Kopfende geschlitzte Stellschraube 28, welche den inneren Rundkontakt 12 in axialer Richtung durchsetzt und sich bis in den Druckregler 10 hinein erstreckt.The inner plug contact 25 (FIG. 6) is also designed as a U-shaped plug contact, the recess of which is formed so that the inner plug contact 25 encompasses and clamps the inner circular contact 12. The inner round contact 12 contains a set screw 28 which is slotted at its head end, which passes through the inner round contact 12 in the axial direction and extends into the pressure regulator 10.
In modularer Bauweise (Fig. 7) enthält ein Ventilgehäuse 29 mehrere Druckregler 30, welche in einer Linie äquidistant zueinander angeordnet sind. Die inneren und äußeren Rundkontakte der einzelnen Druckregler 30 bilden somit eine Kontaktleiste 31. Eine korrespondierende Stekkerleiste 32 enthält mehrere Einzelstecker 33, welche derart angeordnet sind, daß die Stecker 33 gleichzeitig auf die Kontaktleiste 31 aufsteckbar sind. Dabei ist vorteil¬ hafterweise eine Rastnase 24 zur Arretierung des Steckers in Umfangsrichtung, wie in Fig. 4 gezeigt, nicht erforderlich, da sich die Steckerleiste 32 an der Kontaktleiste 31 durch die Anlage mehrerer Stecker 33 an mehreren Druckreglern 30 abstützt und dadurch eine Arretierung der Stecker in Umfangsrichtung erfolgt. In a modular design (FIG. 7), a valve housing 29 contains a plurality of pressure regulators 30 which are arranged equidistantly from one another in a line. The inner and outer round contacts of the individual pressure regulators 30 thus form a contact strip 31. A corresponding plug strip 32 contains a plurality of individual plugs 33, which are arranged in such a way that the plugs 33 open simultaneously the contact strip 31 can be plugged on. It is advantageous ¬ adhesive enough, a detent 24 is shown for locking the plug in the circumferential direction as shown in Fig. 4 is not required, since the connector 32 is supported on the contact strip 31 through the system a plurality of plug 33 at a plurality of pressure regulators 30 and thereby a locking of the Plug is made in the circumferential direction.
