Description

Die Erfindung betrifft ein elektrisches Gerät mit einem Gehäuse und mit einer elektrischen Schaltung im Gehäuse, an die elektrische Verbindungsleitungen angeschlossenen sind.The invention relates to an electrical device with a housing and with an electrical circuit in the housing to which electrical connection lines are connected.

Ein gattungsgemäßes elektrisches Gerät gehört zum Stand der Technik. Üblicherweise werden die von außen zugeführten Verbindungsleitungen umständlich durch eine Öffnung im Gehäuse gefädelt und mittels auf einer Leiterplatine aufgelöteten Schraubklemmen mit der elektrischen Schaltung verbunden. Die dabei verwendeten Leiterquerschnitte sind üblicherweise auf 0,34 mm2 begrenzt.A generic electrical device is part of the prior art. Usually, the connecting lines fed in from outside are laboriously threaded through an opening in the housing and connected to the electrical circuit by means of screw terminals soldered onto a printed circuit board. The conductor cross sections used are usually limited to 0.34 mm 2 .

Der Erfindung liegt die Aufgabe zugrunde, ein elektrisches Gerät der obengenannten Art dahingehend zu verbessern, daß ein einfacher elektrischer Anschluß, auch von größeren Leiterquerschnitten, ermöglicht wird.The invention has for its object an electrical To improve device of the type mentioned above in that a simple electrical connection, even of larger conductor cross-sections, is made possible.

Die Aufgabe wird dadurch gelöst, daß das Gehäuse einen Stutzen aufweist, in dessem Innenraum ein Klemmeneinsatz mit Klemmen angeordnet ist, mittels derer die Verbindungsleitungen mit von außerhalb zugeführten Leitungsadern elektrisch verbindbar sind.The object is achieved in that the housing has a nozzle has a terminal insert in its interior Terminals is arranged, by means of which the connecting lines with electrical wires supplied from outside are connectable.

Besonders vorteilhaft ist es, wenn die Klemmen als Stiftklemmen ausgeführt sind, da dies eine einfache Zuführung der Verbindungsleitungen zu den eigentlichen Schraubklemmen ermöglicht.It is particularly advantageous if the terminals are pin terminals are carried out as this is an easy supply of the connecting lines to the actual screw terminals.

Ist der Stutzen als Gewindestutzen ausgeführt und dient er für eine Kabel-Verschraubung, so wird auf einfache Weise die Dichtheit des elektrischen Anschlusses erreicht. Is the connector designed as a threaded connector and does it serve for a cable gland, so the Tightness of the electrical connection reached.

Weiterhin ist es von besonderem Vorteil, wenn das elektrische Gerät durch die Ausführung als berührungslos arbeitendes Schaltgerät gekennzeichnet ist, da hier die Anforderungen bezüglich An- und Abklemmen der Leitungen auch bei montiertem Gerät üblicherweise auftreten und dies zugleich mit der Forderung nach einer zuverlässigen Abdichtung verbunden ist.Furthermore, it is particularly advantageous if the electrical The device is designed as a non-contact device Switchgear is marked, because here the requirements regarding Connect and disconnect the cables even when the cable is installed Device usually occur and this at the same time with the requirement after a reliable seal is connected.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:

FIG 1
ein erfinderisches elektrisches Gerät mit einem Klemmeneinsatz in einem Gewindestutzen in Verbindung mit einer Kabel-Verschraubung,
FIG 2
eine perspektivische Ansicht des Klemmeneinsatzes gemäß FIG 1 mit zugehörigen Stiftklemmen,
FIG 3

FIG 4
eine Explosionsdarstellung mit dem elektrischen Gerät, dem Klemmeneinsatz und einem zugeführten Kabel.
An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG. 1
an inventive electrical device with a terminal insert in a threaded connector in connection with a cable gland,
FIG 2
2 shows a perspective view of the terminal insert according to FIG. 1 with associated pin terminals,
FIG 3
a longitudinal section through the terminal insert according to FIG 1 and
FIG 4
an exploded view with the electrical device, the terminal insert and a supplied cable.

In FIG 1 ist ein elektrisches Gerät 1 im geöffneten Zustand dargestellt, daß im wesentlichen durch ein Gehäuse 2, eine in dessem Innenraum liegende Schaltung 3, hier in Form einer Leiterplatte verwirklicht, und an die Schaltung 3 angeschlossenen Verbindungsleitungen 4 gekennzeichnet ist. Am Gehäuse 2 ist ein Gewindestutzen 5 vorgesehen, in dessen Hohlraum ein Klemmeneinsatz 6 liegt, der zur Verbindung der Verbindungsleitungen 4 mit Leitungsadern eines von außerhalb zugeführten Kabels 7 dient. Hierzu ist der Klemmeneinsatz 6, wie in FIG 2 dargestellt, mit mehreren Stiftklemmen 8 versehen, deren Stifte in den Innenraum des Gehäuses 2 ragen. FIG 3 zeigt einen Längsschnitt durch den Klemmeneinsatz 6 und den darin steckenden Stiftklemmen 8. Die Verbindungsleitungen 4 werden über die stiftförmigen Enden den Stiftklemmen 8 von der einen Seite zugeführt, während die elektrische Verbindung der Leitungsadern des Kabels 7 über die andere Seite des Klemmeneinsatzes 6 erfolgt. Mittels einer Schraube 9 und einer Dichtung 10 ist in Verbindung mit dem Gewindestutzen 5 gemäß FIG 1 und 4 eine Kabel-Verschraubung realisiert.1 shows an electrical device 1 in the open state shown that essentially by a housing 2, one in whose interior circuit 3, here in the form of a Printed circuit board realized, and connected to the circuit 3 Connection lines 4 is marked. On the housing 2 a threaded connector 5 is provided, in the cavity Terminal insert 6 is the one for connecting the connecting lines 4 with wires one from outside Cable 7 is used. For this purpose, the terminal insert 6, as in FIG. 2 shown, provided with several pin terminals 8, the Protruding pins into the interior of the housing 2. 3 shows a longitudinal section through the terminal insert 6 and the therein inserted pin terminals 8. The connecting lines 4 are over the pin-shaped ends of the pin terminals 8 of one Side fed while the electrical connection of the line wires of cable 7 over the other side of the terminal insert 6 takes place. By means of a screw 9 and a seal 10 is in connection with the threaded connector 5 according to FIG 1 and 4 realized a cable gland.

Gemäß dem vorliegenden Ausführungsbeispiel wird innerhalb der Kabel-Verschraubung die Befestigung eines fünfadrigen Kabels 7 mit Leitungsquerschnitten von jeweils 1,5 mm2 bei gleichzeitiger Abdichtung der Kabeleinführung nach IP 67 erreicht. Der Vorteil dieser Ausführungsform besteht darin, daß das zugeführte Kabel 7 nicht in das Gehäuse 2 geführt werden muß. Bei entsprechender Ausführung des Gewindestutzens 5 ergibt sich ein genügend großer Anschlußraum, der hinsichtlich der Verwendung von Aderendhülsen unkritisch ist.According to the present embodiment, the fastening of a five-core cable 7 with cable cross-sections of 1.5 mm 2 is achieved within the cable gland with simultaneous sealing of the cable entry according to IP 67. The advantage of this embodiment is that the supplied cable 7 does not have to be led into the housing 2. With a corresponding design of the threaded connector 5, there is a sufficiently large connection space which is not critical with regard to the use of wire end ferrules.

Die Verbindungsleitungen 4 haben eine solche Länge, daß sie bei herausgezogenem Klemmeneinsatz 6 außerhalb des Geräts 1 durch die Stiftklemmen 8 festgeklemmt werden können. Nach der elektrischen Verbindung der Verbindungsleitungen 4 mit den Leitungsadern des Kabels 7 mittels des Klemmeinsatzes 6 wird dieser in den Gewindestutzen 5 eingesteckt und anschließend durch die Kabel-Verschraubung befestigt und abgedichtet. Das An- und Abklemmen kann demzufolge auch bei montiertem Gerät 1 erfolgen.The connecting lines 4 have such a length that they with the terminal insert 6 pulled out outside the device 1 can be clamped by the pin terminals 8. After electrical connection of the connecting lines 4 with the Line wires of the cable 7 by means of the clamping insert 6 this is inserted into the threaded connector 5 and then fixed and sealed by the cable gland. The Accordingly, connecting and disconnecting can also be carried out when the device is 1 respectively.
