Definitions
- the invention relates to a connection device for the electrical connection of a polyphase electric motor with a voltage connection according to the preamble of claim 1.
- Polyphase electric motors with a capacity of z. 2,000 watts are used in large numbers and - depending on the application on site - electrically wired either star connection or delta connection in the motor terminal box. This wiring is done manually on site and requires a lot of time. Changes to the circuit or the direction of rotation of the motor must always be carried out in the motor connection box by reconnecting the corresponding connections. As with all manual work, errors can occur.
- the documents US 20040253876 and US 3525971 are examples of flexible connectors and adapters.

This largely avoids circuit errors.
- the adapter connects depending on its rotational position, the lines in a predetermined assignment with each other. To this rotational position of the adapter too fix, this is accommodated in an adapter housing. This makes it possible that the adapter is used in a first rotational position for a clockwise rotation of the motor and in a second rotational position for a counterclockwise rotation of the motor in the adapter housing. If the user detects after connecting the motor that the motor has the wrong direction of rotation, he only has to reinsert the adapter part in the adapter housing rotated by 180 °. The connections on the motor side as well as on the mains connection side do not need to be changed.
- the adapter is connected via connectors to the lines, so that another electrical wiring - star connection instead of delta connection - by replacing the adapter is easily possible.

Mehrphasige Elektromotoren mit einer Leistung von z. B. 2.000 Watt werden in großer Stückzahl eingesetzt und sind - je nach Einsatz vor Ort - elektrisch entweder in Sternschaltung oder Dreieckschaltung im Motoranschlusskasten zu verdrahten. Diese Verdrahtung erfolgt vor Ort manuell und erfordert viel Zeitaufwand.

Der Erfindung liegt die Aufgabe zugrunde, die elektrische Installation von mehrphasigen Elektromotoren zu vereinfachen.The invention has for its object to simplify the electrical installation of multi-phase electric motors.
Die Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the characterizing features of
Nach der Erfindung wird zwischen den Motorleitungen des Elektromotors und den Anschlussleitungen des Netzes der Adapter angeordnet, der ein eigenständiges, auswechselbares Bauteil ist und zwischen seinen axialen, stirnseitigen Anschlussseiten derart verdrahtet ist, dass der Adapter - je nach Einsatzfall - jede einzelne Anschlussleitung des Spannungsanschlusses mit einer einzelnen Motorleitung des Elektromotors verbindet.According to the invention, the adapter is arranged between the motor lines of the electric motor and the connection lines of the network, which is an independent, interchangeable component and is wired between its axial, front-side connection sides such that the adapter - depending on the application - each individual connection line of the voltage terminal with a single motor line of the electric motor connects.
Der Adapter ist derart ausgebildet, dass die Motorleitungen auf der Motorseite in fester, unveränderbarer Zuordnung elektrisch mit dem Adapter kontaktiert werden, wie auch auf der Netzanschlussseite der Netzanschluss in fester Zuordnung mit dem Adapter kontaktiert wird. Innerhalb des Adapters sind die Verbindungen je nach Einsatzfall verdrahtet. So kann ein erster Adapter für eine elektrische Dreieckschaltung des Motors ausgebildet sein und ein anderer Adapter für eine Sternschaltung der Motorwicklungen des anzuschließenden Motors. Der Benutzer wählt je nach geforderter elektrischer Beschaltung den einen oder den anderen Adapter aus, um den Motor in Stern- bzw. in Dreieckschaltung anzuschließen. Da auf den Anschlussseiten eine feste Zuordnung zu den Motorleitungen bzw. den Anschlussleitungen gegeben ist, schließt der Benutzer - unabhängig von der elektrischen Beschaltung des Motors - den Motor selbst in immer gleicher Weise manuell an. Damit werden Schaltungsfehler weitgehend vermieden.The adapter is designed such that the motor cables are contacted on the motor side in a fixed, unchangeable assignment electrically to the adapter, as well as on the network connection side of the power connector is contacted in fixed association with the adapter. Within the adapter, the connections are wired depending on the application. Thus, a first adapter for a delta electric circuit of the motor may be formed and another adapter for a star connection of the motor windings of the motor to be connected. The user selects depending on the required electrical wiring one or the other adapter to connect the motor in star or delta connection. Since there is a fixed assignment to the motor cables or the connection lines on the connection sides, the user - regardless of the electrical wiring of the motor - closes the motor manually in always the same way. This largely avoids circuit errors.
In Weiterbildung der Erfindung verbindet der Adapter abhängig von seiner Drehlage die Leitungen in einer vorgegebenen Zuordnung miteinander. Um diese Drehlage des Adapters zu fixieren, wird dieser in einem Adaptergehäuse aufgenommen. Damit wird es möglich, dass der Adapter in einer ersten Drehlage für einen Rechtslauf des Motors und in einer zweiten Drehlage für einen Linkslauf des Motors in das Adaptergehäuse einsetzbar ist. Stellt der Benutzer nach Anschluss des Motors fest, dass dieser die falsche Drehrichtung hat, so muss er lediglich das Adapterteil im Adaptergehäuse um 180° verdreht wieder einsetzen. Die Anschlüsse auf der Motorseite wie auf der Netzanschlussseite müssen nicht verändert werden.In a further development of the invention, the adapter connects depending on its rotational position, the lines in a predetermined assignment with each other. To this rotational position of the adapter too fix, this is accommodated in an adapter housing. This makes it possible that the adapter is used in a first rotational position for a clockwise rotation of the motor and in a second rotational position for a counterclockwise rotation of the motor in the adapter housing. If the user detects after connecting the motor that the motor has the wrong direction of rotation, he only has to reinsert the adapter part in the adapter housing rotated by 180 °. The connections on the motor side as well as on the mains connection side do not need to be changed.
In Weiterbildung der Erfindung ist der Adapter über Steckverbindungen mit den Leitungen verbunden, so dass eine andere elektrische Beschaltung - Sternschaltung statt Dreieckschaltung - durch Austausch des Adapters leicht möglich ist.In a further development of the invention, the adapter is connected via connectors to the lines, so that another electrical wiring - star connection instead of delta connection - by replacing the adapter is easily possible.
Wird das Adaptergehäuse einteilig mit dem Steckanschluss der Motorleitungen ausgebildet, so kann ein üblicher Motoranschlusskasten entfallen; das Adaptergehäuse bildet den Motoranschlusskasten selbst, während der in das Adaptergehäuse eingesetzte Adapter die notwendige elektrische Verdrahtung herstellt.If the adapter housing is formed integrally with the plug connection of the motor cables, a conventional motor connection box can be dispensed with; The adapter housing forms the motor connection box itself, while the adapter inserted into the adapter housing produces the necessary electrical wiring.
In Weiterbildung der Erfindung ist der Adapter als eigenständiger Steckverbinder ausgeführt, wobei der Adapter vorteilhaft zusammen mit dem Netzanschluss eine montierbare Baueinheit bildet.In a further development of the invention, the adapter is designed as a stand-alone connector, wherein the adapter advantageously forms a mountable assembly together with the mains connection.
