Description

Die Kraftsteckdose sowie der Kraftstecker können aus Eisen oder Leichtmetall hergestellt sein und sind mit Kontakteinsätzen aus Isoliermaterial, wie Porzellan, Steatit usw. und mit Kontaktbuchsen für den Anschluß an das elektrische Leitungsnetz ausgerüstet.The power socket and the power plug can be made of iron or light metal be made and are with contact inserts made of insulating material, such as porcelain, Steatite etc. and with contact sockets for connection to the electrical network equipped.

Gekennzeichnet ist die Kraftsteckdose dadurch, daß über und unter der mittleren Steckbuchse der Phasenanschlüsse je eine Buchse für den Nulleiter angeschlossen ist, die beide miteinander elektrisch verbunden sind, so daß durch die Umwechslung des Kraftsteckers an der Kraftsteckdose eine Drehrichtungsumkehr des Motors erfolgt, zugleich aber durch die elektrische Verbindung der beiden Nulleiterbuchsen die erforderliche vorschriftsmäßige Nullung erzielt wird, was bei den derzeitigen Kraftsteckdosen nicht möglich ist.The power socket is characterized by the fact that above and below the middle socket of the phase connections each has a socket for the neutral conductor is connected, both of which are electrically connected to each other, so that through changing the power plug to the power socket means reversing the direction of rotation of the motor, but at the same time through the electrical connection of the two neutral conductor sockets the required zeroing in accordance with the regulations is achieved, as is the case with the current Power sockets is not possible.

Besonders gekennzeichnet ist die Erfindung noch durch die senkrechte Anordnung der beiden Nullleiterbuchsen bei der Kraftsteckdose zu den Phasenanschlüssen, welche elektrisch miteinander verbunden sind und auch noch eine andere Anordnung mit der gleichen Wirkungsweise zulassen. Die Kraftsteckdose ist mit fünf Kontaktbuchsen ausgerüstet. Drei davon sind für die Phasenanschlüsse und zwei für die Nullungsanschlüsse. Letztere sind elektrisch miteinander verbunden. Bei den bisherigen Kraftsteckdosen mit ihren drei bzw. vier Kontaktstiften in der Kraftsteckdose war eine Drehrichtungsumkehr durch die Umwechslung des Kraftsteckers an der Kraftsteckdose, bei welcher zugleich die erforderliche vorschriftsmäßige Nullung sichergestellt wird; nicht möglich.The invention is particularly characterized by the vertical Arrangement of the two neutral conductor sockets at the power socket to the phase connections, which are electrically connected to each other and also another arrangement allow with the same mode of action. The power socket has five contact sockets equipped. Three of them are for the phase connections and two for the zero connections. The latter are electrically connected to each other. With the previous power sockets with its three or four contact pins in the power socket, the direction of rotation was reversed by changing the power plug to the power socket, which at the same time the required zeroing in accordance with regulations is ensured; not possible.

PATENTANSPRUCH: Dreipolige Steckdose mit einer Buchse für Erdung zum Anschluß von Drehstrommotoren, dadurch gekennzeichnet, daß über und unter der mittleren Steckbuchse für die Phasenanschlüsse je eine Buchse für den Nullleiter vorgesehen ist, die beide miteinander elektrisch verbunden sind, so daß durch das Umwechseln des Steckers, je nachdem der Steckerstift für den Nulleiter in die obere oder untere Steckbuchse eingreift, ein Umschalten der Drehrichtung des Drehstrommotors erfolgt.PATENT CLAIM: Three-pin socket with a socket for grounding to the Connection of three-phase motors, characterized in that above and below the middle Socket for the phase connections, one socket each for the neutral conductor is, both of which are electrically connected to each other, so that by switching of the plug, depending on the plug pin for the neutral conductor in the upper or lower Socket engages, the direction of rotation of the three-phase motor is switched.
