Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bewegliche Stromverbraucher, wie z. B. Handbohrmaschinen, Staubsauger, Prüftransformatoren usw., müssen mittels Steckdosen und Stecker an verschiedenen Orten anschließbar sein. Zur Sicherung der Bedienung ist Erdung der Metallgehäuse dieser Apparate erforderlich. Das Zuführungsmittel erhält zu diesem Zweck eine Erdleitung und der Stecker einen Erdungskontakt. Die Steckvorrichtungen bieten aberMovable electricity consumers, such as B. hand drills, vacuum cleaners, test transformers etc., must be able to be connected by means of sockets and plugs in different places be. To ensure operation, the metal housing of these devices must be grounded. For this purpose, the supply means is provided with an earth line and the plug is provided with an earth contact. The plugs offer but

ίο für dauernd guten Kontakt keine genügende Sicherheit. Bei den Stromzuführungen macht sich schlechter Kontakt sofort bemerkbar, bei dem Erdungskontakt jedoch nicht. Gegenstand der Erfindung ist daher eine solche Ausbildung der Steckvorrichtung, daß nur bei gutem Erdungskontakt Strom entnommen werden kann.ίο not enough for permanent good contact Safety. In the case of the power supply, bad contact is immediately noticeable at but not the ground contact. The subject of the invention is therefore such a training the plug-in device that current can only be drawn with a good earth contact.

Zu diesem Zweck enthält die Steckdose A eine an sich bekannte Federanordnung C, welche den Stecker B herauszudrücken, also stromlos zu machen bestrebt ist, während eine Klemmvorrichtung D den Stecker am Erdungskontakt festklemmt. Nur wenn diese Klemmvorrichtung angezogen ist, bleibt der Stecker in der Einschaltstellung. Dann ist aber auch guter Anschluß an die Erdleitung gewährleistet.For this purpose the socket A contains a spring arrangement C known per se, which tries to push out the plug B , that is to say to make it currentless, while a clamping device D clamps the plug on the grounding contact. The plug only remains in the on position when this clamping device is tightened. But then a good connection to the earth line is also guaranteed.

Die Klemmvorrichtung besteht am einfachsten aus einer von Hand anzuziehenden Schraube, wie in der Zeichnung dargestellt, sie kann jedoch auch eine selbsttätige Friktionseinrichtung sein. Wesentlich ist nur, daß die das Herausdrücken des Steckers durch die Feder verhindernde Klemmung zugleich die Erdverbindung bewirkt. Drückt die Klemmvorrichtung so stark, daß sie den Stecker festhält, so gibt sie auch eine sichere Erdverbindung. The easiest way to use the clamping device is to tighten it by hand Screw, as shown in the drawing, but it can also be an automatic friction device be. It is only essential that the clamping which prevents the plug from being pushed out by the spring is at the same time causes the earth connection. If the clamping device presses so hard that it holds the plug in place, so it also gives a secure earth connection.

Claims (1)

Patent-Anspruch:Patent claim: Steckanschluß mit Erdungskontakt, dadurch gekennzeichnet, daß der Stecker entgegen der Wirkung einer Feder, welche ihn aus der Steckdose in an sich bekannter Weise herauszudrücken sucht, durch eine den Erdungskontakt verbessernde Klemm- 4^ Vorrichtung geschlossen gehalten wird.Plug-in connection with grounding contact, characterized in that the plug is held device 4 ^ closed against the action of a spring which seeks to push out it from the socket in a known manner by a ground contact improving clamping.
