Description
<B>Zweipoliger</B> Schutzkontaktstecker <B>mit</B> Stifterdung Es gibt Stecker, die zur Befestigung des t seliäusedeckels vier Befestigungslöcher be sitzen. Von diesen Befestigungslöchern werden aber jeweils nur zwei Löcher benützt, die auf derjenigen Gehäuseseite liegen, in die das Kabel eingeführt wird. Die andern beiden ljöeher befinden sich auf der gegenüberliegen den Seite im Gehäuse und werden gebraucht, wenn die zweite Kabeleinführung Verwen dung findet.
Auf diese Weise erfolgt also die Befestigung des Deckels nur einseitig, wo- dureh auf der andern Seite leicht ein Spalt zwischen Deckel und Unterteil entstehen kann. Ausserdem müssen im Deckel vier Befesti- gnngslöclier vorgesehen werden, was zu einer za komplizierten Ausbildung dies Deckels führt.
Dies zu vermeiden, ist der Zweck der vor liegenden Erfindung.
Der erfindungsgemässe zweipolige Sehutz- kontaktsteeker mit. Stifterdung, mit querge teiltem Gehäuse und zwei seitlichen Kabel einführungen ist dadurch gekennzeichnet, class der Gehäusedeckel nur mit einer Befesti- gungsschraube befestigt ist, welche Schraube in der Mitte des Gehäuses angeardnet ist.
Zweekmä.ssi.gerweise greift die Befesti- gungssehraube in den waagrechten Teil des Erdungsstiftes und weiter in ein zusätzliches Loch des Unterteils ein. Die übrigen vier Löcher seitlich der Kabelzuführungen können dann jeweils zwei zu zwei für eine Zugent- lastungsschelle verwendet. werden.
Ein Ausführungsbeispiel des Erfindungs- gegenstandes ist in der beiliegenden Zeich nung dargestellt, und zwar in Fig. 1 im Schnitt und in Fig. 2 in Draufsicht bei abgenommenem Deckel.
Der Deckel 1 (Fig. 1) des Steckerg,ehäuses besitzt in seiner Mitte ein Loch für die Auf- nahine der Befestigungsschraube 2. Die Befe stigungsschraube 2 greift in den waagrecht abgewinkelten Teil 3 des Erdungsstiftes 4 und in das zusätzlich in dem Gehäuseunterteil 5 (Fig. 2) vorgesehene Loch 6 ein. Die übrigen vier Löcher im Gehäuseunterteil können zur Anbringung einer Zugentlastungssehelle für das Kabel .benutzt werden.
Die Innenfläche des Deckels ist dann ebenflächig über den Kabelführungen ausgebildet.
<B> Two-pole </B> earthing contact <B> with </B> pin earthing There are plugs that have four fastening holes for fastening the housing cover. Of these fastening holes, only two holes are used, which are located on the side of the housing into which the cable is inserted. The other two ljöeher are located on the opposite side in the housing and are needed when the second cable entry is used.
In this way, the cover is only fastened on one side, whereby a gap can easily arise between the cover and the lower part on the other side. In addition, four fastening holes must be provided in the cover, which leads to a complicated design of this cover.
Avoiding this is the purpose of the present invention.
The inventive two-pole protective contact teeker with. Pin earthing, with transversely divided housing and two cable entries on the side, is characterized by the fact that the housing cover is only fastened with one fastening screw, which screw is attached in the middle of the housing.
The fastening tube engages in the horizontal part of the earthing pin and then in an additional hole in the lower part. The other four holes on the side of the cable feeds can then be used two to two for a strain relief clip. will.
An embodiment of the subject matter of the invention is shown in the accompanying drawing, namely in Fig. 1 in section and in Fig. 2 in plan view with the cover removed.
The cover 1 (Fig. 1) of the connector housing has a hole in its center for receiving the fastening screw 2. The fastening screw 2 engages in the horizontally angled part 3 of the grounding pin 4 and also in the lower part of the housing 5 ( Fig. 2) provided hole 6 a. The other four holes in the lower part of the housing can be used to attach a strain relief clamp for the cable.
The inner surface of the cover is then flat over the cable guides.
