Description

Die Erfindung betrifft eine elektromechanische Verbindungsvorrichtung nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to an electromechanical connecting device according to the preamble of claim 1 Art.

Eine Verbindungsvorrichtung dieser Art ist in der EP 0 573 471 B1 beschrieben. Durch die vorbekannte Verbindungsvorrichtung, die aus einer Schalteinrichtung, die die Funktion einer Steckdose herkömmlicher Art übernimmt, und einer Auslöseeinrichtung, die die Funktion eines Steckers übernimmt, besteht, wird eine Verbindungsvorrichtung geschaffen, die eine sehr geringe Bautiefe aufweist und die darüberhinaus hohen Sicherheitsanforderungen entspricht.A connection device of this type is described in EP 0 573 471 B1. Through the known connection device, the from a switching device that the function a conventional socket, and one Tripping device that takes over the function of a plug, a connection device is created, which has a very shallow depth and beyond that meets high security requirements.

Bei der elektromechanischen Verbindungsvorrichtung nach der EP 0 573 471 B1 erfolgt sowohl der mechanische als auch der elektrische Kontakt über Magnete. Hierzu sind sowohl der Arbeitsschlitten, der mit Stromzuführungskontakten verbindbar ist, als auch die Schaltmagnete elektrisch leitend. Die Stromverbindung wird direkt über Kontakthütchen zu Auslösemagnete in der Auslöseeinrichtung geleitet, die ebenfalls elektrisch leitend sind. Die Magnete sind außenseitig von einem Erdungsring umgeben, der bündig in das elektrisch isolierende Gehäuse der Schalteinrichtung eingelassen ist. Nachteilig bei dieser Stromführung ist jedoch, daß eine elektrische Leitfähigkeit im Falle eines Kurzschlusses zu einem Verlust der hitzeempfindlichen magnetischen Bauteile führt. Außerdem ist die vorbekannte Vorrichtung aufgrund der Spannungs- und Stromleitung über die Kontakthütchen und die Magnete noch relativ breit gebaut.According to the electromechanical connection device EP 0 573 471 B1 is both mechanical and also the electrical contact via magnets. For this are both the work sled, the one with power supply contacts is connectable, as well as the switching magnets electrically conductive. The power connection is made directly via contact caps to release magnets in the release device conducted, which are also electrically conductive. The magnets are surrounded on the outside by an earthing ring, the flush in the electrically insulating housing of the switching device is let in. A disadvantage of this current routing is that an electrical conductivity in the In the event of a short circuit to a loss of the heat sensitive leads magnetic components. Besides, that is previously known device due to the voltage and power line relative to the contact caps and the magnets broadly built.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die eingangs erwähnte elektromechanische Verbindungsvorrichtung weiter zu verbessern, insbesondere eine noch höhere Sicherheit zu gewährleisten und die magnetische Haftkraft zu erhöhen.The present invention is therefore based on the object the above-mentioned electromechanical connection device continue to improve, especially one more ensure higher security and the magnetic To increase adhesive force.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil von Anspruch 1 genannten Merkmale gelöst.According to the invention, this task is characterized by Part of claim 1 mentioned features solved.

Erfindungsgemäß werden nunmehr die Magnete nicht mehr an der Strom- bzw. Spannungsführung beteiligt d. h., sie stehen nicht mehr unter Spannung. Der Strom selbst wird gesondert über Kontaktpaare geleitet. Dies bedeutet, es ist auch für den Arbeitsschlitten, der den Kontakt zu den Stromzuführungskontakten herstellt, nur noch eine elektrisch leitende Brücke erforderlich. Der Arbeitsschlitten selbst kann zusammen mit den darauf angeordneten Schaltmagneten elektrisch nichtleitend sein.According to the invention, the magnets are now no longer on the current or voltage management involved d. that is, they stand no longer under tension. The electricity itself is separated routed via contact pairs. This means it is also for the work sledge that is in contact with the Produces power supply contacts, only one electrical conductive bridge required. The work sledge itself, together with the switching magnets arranged on it be electrically non-conductive.

Bei einer Anordnung der Kontaktpaare im inneren Bereich ist eine weitere Sicherheitserhöhung gegeben. Darüber hinaus können die Kontaktpaare stabiler und sicherer, z.B. in Form von breiten Kontaktstiften ausgebildet sein.With an arrangement of the contact pairs in the inner area there is a further increase in security. Furthermore the contact pairs can be more stable and secure, e.g. in Be in the form of wide contact pins.

Ein weiterer Vorteil der erfindungsgemäßen Trennung der Magnete von der Stromführung besteht darin, daß sich auf diese Weise keine Wärmeprobleme bei den Magneten ergeben, da diese ja nicht mehr an der Stromführung beteiligt sind. Kommt es beispielsweise zu einem Kurzschluß, werden die Magnete nicht durch Hitzeeinwirkung beschädigt. Auch kann Wärme, die durch einen etwaigen Feuchtigkeitsfilm entsteht, über den Erdungsring auf einfache Weise abgeleitet werden. Dies ist insbesondere dann der Fall, wenn die Schaltmagnete und die Auslösemagnete in geschaltetem Zustand mit dem Erdungsring in Kontakt stehen.Another advantage of the separation of the invention Magnets from the power supply is that on this way there are no heat problems with the magnets, since these are no longer involved in the power supply. If there is a short circuit, for example, the Magnets not damaged by exposure to heat. Can too Heat generated by any film of moisture easily derived via the earthing ring become. This is particularly the case if the Switching magnets and the tripping magnets in the switched state be in contact with the earthing ring.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung kann darin bestehen, daß der Arbeitsschlitten wenigstens annähernd kreisförmig ausgebildet ist, und daß mehrere Schaltmagnete im äußeren Umfangsbereich des Arbeitsschlittens auf Abstand voneinander angeordnet sind.Another very advantageous embodiment of the invention can be that the work sled at least is approximately circular, and that several Switching magnets in the outer circumferential area of the work slide are arranged at a distance from each other.

Wenn dabei die Magnetteile in entsprechenden Codierungen angeordnet sind, z.B. in alternierenden Nord-Süd-Kombinationen mit 180°-Symmetrie, läßt sich ein sehr schnelles Zurückschalten des Arbeitsschlittens bei Verdrehungen der Auslöseeinrichtung erreichen. Bedingt durch die dabei auftretenden größeren Winkellängen entstehen schon bei kleinen Verdrehungen gegensinnige Felder und damit entsprechend hohe abstoßende Kräfte, so daß der Arbeitsschlitten in den nicht geschalteten Ruhezustand zurückkehrt.If doing so the magnetic parts in appropriate codings are arranged, e.g. in alternating north-south combinations with 180 ° symmetry, can be a very fast Downshifting of the work carriage when the Reach tripping device. Due to the occurring Larger angular lengths arise even with small ones Twists opposing fields and thus accordingly high repulsive forces so that the work sled returns to the non-switched idle state.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus weiteren Unteransprüchen und aus den nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispielen.Advantageous refinements of the invention result from further subclaims and from the following the drawing described in principle embodiments.

Die elektromechanische Verbindungsvorrichtung besteht aus einer Schalteinrichtung 1, die die Funktion einer herkömmlichen Steckdose ersetzt und im allgemeinen an einer gewünschten Stelle fest eingebaut ist, und aus einer Auslöseeinrichtung 2, die die Funktion eines herkömmlichen Steckers ersetzt, welcher im allgemeinen mit einem Verbraucher verbunden ist oder welcher direkt an den Verbraucher angeordnet ist. Sobald eine elektrisch leitende Verbindung zwischen der Schalteinrichtung 1 und der Auslöseeinrichtung 2 geschaffen ist, wird der jeweilige mit der Auslöseeinrichtung 2 verbundene Verbraucher entsprechend mit Strom versorgt.The electromechanical connection device consists of a switching device 1, the function of a conventional Socket replaced and generally at a desired one Place is permanently installed, and from a release device 2, the function of a conventional Plug replaced, which is generally with a consumer connected or which directly to the consumer is arranged. Once an electrically conductive connection between the switching device 1 and the triggering device 2 is created, the respective with the Trigger device 2 connected consumers accordingly powered.

Grundsätzlich ist die Schalteinrichtung 1 und die Auslöseeinrichtung 2 von einem gleichen Aufbauprinzip wie die in der EP 0 573 471 B1 beschriebene elektromechanische Verbindungsvorrichtung. So weist die Schalteinrichtung 1 eine geschlossene Baueinheit in einem zweiteiligen Gehäuse 3 auf. Im Ruhezustand, d.h. wenn die Auslöseeinrichtung 2 nicht auf die Schalteinrichtung 1 aufgesetzt ist, ist ein Arbeitsschlitten 4, auf dem Schaltmagnete 5 in Form von Magnetteilen mit unterschiedlichen Polaritäten angeordnet sind, durch eine ferromagnetische Rückhalteplatte 7 auf dem Boden des Gehäuses 3 gehalten. Die ferromagnetische Rückhalteplatte kann auch ein Magnetring 7 sein.Basically, the switching device 1 and the triggering device 2 has the same construction principle as that in the electromechanical connecting device described in EP 0 573 471 B1. Thus, the switching device 1 has one closed structural unit in a two-part housing 3 on. At rest, i.e. if the release device 2 is not placed on the switching device 1 is a Working carriage 4, on the switching magnet 5 in the form of Magnetic parts arranged with different polarities are, by a ferromagnetic retaining plate 7 held the bottom of the housing 3. The ferromagnetic Retaining plate can also be a magnetic ring 7.

Die Schaltmagnete 5 sind im äußeren Umfangsbereich des kreisförmigen Arbeitsschlittens 4 angeordnet. Wie aus Fig. 4 ersichtlich ist, sind dabei die als magnetisch codierte Magnetteile ausgebildeten Schaltmagnete 5 gemäß Ausführungsbeispiel nach den Fig. 1 bis 4 und Fig. 7 in insgesamt vier Vierergruppen über den Umfang verteilt angeordnet. Jede Gruppe besteht somit aus vier codierten Magnetteilen 5a bis 5d mit je zwei Nord- und zwei Südpolen, die so zueinander angeordnet sind, daß jeweils unterschiedliche Polaritäten aneinander angrenzen. Dies bedeutet, im äußeren Bereich liegen ein Süd- und ein Nordpol nebeneinander, und im inneren Bereich liegen sich ein Nord- und ein Südpol gegenüber.The switching magnets 5 are in the outer peripheral region of the circular work slide 4 arranged. As from Fig. 4 can be seen, are those encoded as magnetically Magnetic parts designed switching magnet 5 according to the embodiment according to FIGS. 1 to 4 and FIG. 7 in total four groups of four arranged around the circumference. Each group thus consists of four coded magnetic parts 5a to 5d, each with two north and two south poles, which are arranged in such a way that each different Adjacent polarities. This means, in the outer area are a south and a north pole side by side, and lie in the inner area North and south poles opposite.

Jede Gruppe mit den auf diese Weise codierten Magnetteilen 5a, 5b, 5c oder 5d ist so im Inneren der Schalteinrichtung 1 angeordnet und weist eine derartige Höhe auf, daß sie auch im nichtgeschalteten Zustand wenigstens in ihrem oberen Bereich in einem Führungsring 6 geführt sind. Hierzu tauchen sie entsprechend im oberen Bereich in den Führungsring 6 ein. Der Führungsring 6 stellt gleichzeitig einen Erdungsring dar, wozu er entsprechend mit einer nicht dargestellten Kontakteinrichtung verbunden ist, die mit einer in die Schalteinrichtung mündenden Erdungsleitung verbunden ist.Each group with the magnetic parts encoded in this way 5a, 5b, 5c or 5d is thus inside the switching device 1 arranged and has such a height that it even in the non-switched state, at least in its upper one Area are guided in a guide ring 6. For this immerse them accordingly in the upper area in the guide ring 6 a. The guide ring 6 provides at the same time a grounding ring, which is why it is connected with a Contact device, not shown, is connected, the with an earthing line opening into the switching device connected is.

Vier gleichmäßig über den Umfang verteilt angeordnete Rückstellfedern 8 sorgen dafür, daß der Arbeitsschlitten 4 zusätzlich durch eine entsprechende Federkraft im nichtgeschalteten Zustand auf dem Magnetring 7 gehalten ist. Gleichzeitig sorgen sie dafür, daß nach einem Abnehmen der Auslöseeinrichtung 2 von der Schalteinrichtung 1 oder einem entsprechenden Verdrehen der beiden Teile zueinander der Arbeitsschlitten 4 wieder zur Anlage auf dem Magnetring 7 gebracht wird. Wie aus den Fig. 2 und 4 ersichtlich ist, sind die Rückstellfedern 8 ebenfalls in dem Führungsring 6 geführt. Dabei befinden sie sich jeweils in Freiräumen zwischen den Schaltmagneten.Four evenly distributed over the circumference Return springs 8 ensure that the work slide 4th additionally by a corresponding spring force in the non-switched State is held on the magnetic ring 7. At the same time, they ensure that after a decrease in Tripping device 2 from the switching device 1 or one corresponding rotation of the two parts to each other the work slide 4 back to the system on the magnetic ring 7 is brought. As can be seen from FIGS. 2 and 4 is, the return springs 8 are also in the guide ring 6 led. They are located in open spaces between the switching magnets.

Aus der Fig. 4 -ist die Stromzuführung am deutlichsten ersichtlich. Mit "9" ist eine stromführende Leitung und mit "10" ein Nulleiter dargestellt. Die beiden Leitungen werden auf der Innenseite eines Deckels 11 des Gehäuses 3 zu Stromzuführungskontakten 12 geleitet. Eine elektrisch leitende Brücke 13 stellt im geschalteten Zustand jeweils eine Stromverbindung von den Stromzuführungskontakten 12 zu dem entsprechenden Kontaktstift 14 her. Dies bedeutet, ein Kontaktstift 14 ist der Phasenleitung 9 und der zweite Kontaktstift 14 ist dem Nulleiter 10 zugeordnet. Beide Kontaktstifte 14 sind in dem Deckel 11 des Gehäuses 3 angeordnet und auf der Oberseite mit dem Deckel bündig.The power supply can be seen most clearly from FIG. 4. With "9" is a live line and with "10" represents a neutral. The two lines will on the inside of a cover 11 of the housing 3 Power supply contacts 12 passed. An electrically conductive Bridge 13 provides in the switched state in each case a power connection from the power supply contacts 12 to the corresponding contact pin 14 ago. This means, a contact pin 14 is the phase line 9 and the second Contact pin 14 is assigned to the neutral conductor 10. Both Contact pins 14 are arranged in the cover 11 of the housing 3 and flush with the lid on the top.

Aus den Fig. 1 und 3 ist ersichtlich, daß jede der beiden Brücken 13 elastisch bzw. federnd auf dem Arbeitsschlitten 4 angeordnet ist, um Toleranzungenauigkeiten auszugleichen, ebenso wie Verschleiß, damit stets ein guter Kontakt gewährleistet ist.1 and 3 that each of the two Bridges 13 elastic or resilient on the work slide 4 is arranged to compensate for tolerance inaccuracies, as well as wear, so that there is always good contact is guaranteed.

Die Auslöseeinrichtung 2, welche ebenfalls ein geschlossenes Gehäuse 15 mit einem Deckel 16 aufweist, ist mit Auslösemagneten 17 versehen, die ebenfalls jeweils aus codierten Magnetteilen gebildet sind. Die Auslösemagnete 17 sind in gleicher Weise und an gleicher Stelle in vier Vierergruppen gemäß Ausführungsbeispiel nach den Fig. 1 bis 4 und Fig. 7 angeordnet. Jede Gruppe ist dabei bezüglich ihrer Polarität so ausgebildet, daß jeweils unterschiedliche Polaritäten im Vergleich zu den Magnetteilen 5a bis 5d der Schaltmagnete 5 der Schalteinrichtung 1 einander gegenüberliegen. Dies bedeutet, bei korrekter Positionierung der Auslöseeinrichtung 2 auf der Schalteinrichtung 1 liegen sich jeweils Nord- und Südpole gegenüber. Auf diese Weise wird der gewünschte Schaltzustand und damit die Stromführung zu dem Verbraucher erreicht. Zu diesem Zweck ist die Auslöseeinrichtung 2 mit entsprechenden zu einem Verbraucher führenden Leitungen 26 und 27 versehen, sofern die Auslöseeinrichtung 2 nicht direkt im oder an dem Verbraucher angeordnet ist.The trigger device 2, which is also a closed Housing 15 with a lid 16 is with release magnets 17 provided, each also encoded Magnetic parts are formed. The release magnets 17 are in the same way and in the same place in four groups of four according to the embodiment of FIGS. 1 to 4 and Fig. 7 arranged. Each group is related their polarity so designed that different Polarities compared to the magnetic parts 5a to 5d the switching magnet 5 of the switching device 1 are opposite each other. This means when positioned correctly the trigger device 2 lie on the switching device 1 facing each other north and south poles. To this Way the desired switching state and thus the Current supply to the consumer reached. To this end is the trigger device 2 with corresponding to one Provide consumer leading lines 26 and 27, if the trigger device 2 is not directly in or on the consumer is arranged.

Ebenso wie die Kontaktstifte 14 in einem Bereich zwischen der Gehäusemitte und den Schaltmagneten 5 angeordnet sind, sind zwei Kontaktstifte 18 in dem Gehäuse 15 im Bereich zwischen der Gehäusemitte und den Auslösemagneten 17 angeordnet. Die Kontaktstifte 18 sind durch Federn 19 in Bohrungen des Gehäuses 15 derart verschiebbar, daß sie mit ihren vorderen Enden aus dem Gehäuse 15 in Richtung auf die Schalteinrichtung 1 geringfügig vorragen. Dies bedeutet, daß bei einer Auflage der Auslöseeinrichtung 2 auf der Schalteinrichtung 1 und damit bei einer elektrischen Kontaktschaltung ein entsprechend sicherer Kontakt gegeben ist (siehe Fig. 3). In diesem Falle werden die Kontaktstifte 18 gegen die Kraft der Feder 19 entsprechend zurückgeschoben.Just like the contact pins 14 in an area between the middle of the housing and the switching magnet 5 are arranged, are two contact pins 18 in the housing 15 in the area arranged between the center of the housing and the release magnet 17. The contact pins 18 are bored by springs 19 of the housing 15 so displaceable that it with their front ends from the housing 15 towards the switching device 1 protrude slightly. This means, that with a support of the trigger device 2 the switching device 1 and thus in an electrical Contact switching given a correspondingly safe contact is (see Fig. 3). In this case, the contact pins 18 pushed back against the force of the spring 19 accordingly.

Die Auslöseeinrichtung 2 ist ebenfalls mit einem Erdungsring 20 versehen, der dem Erdungsring 6 der Schalteinrichtung 1 gegenüberliegt. Zusätzlich ist der Erdungsring 20 der Auslöseeinrichtung 2 mit über den Umfang verteilt angeordneten Erdungsstiften 21 versehen, die jeweils unter Vorspannung durch eine Feder 22 stehen und damit in Richtung auf die Schalteinrichtung 1 aus dem Gehäuse 15 federnd vorstehen.The trigger device 2 is also with an earthing ring 20 provided the grounding ring 6 of the switching device 1 is opposite. In addition, the ground ring is 20th the release device 2 with distributed over the circumference Ground pins 21 provided, each under Prestress by a spring 22 and thus in the direction to the switching device 1 from the housing 15 resilient protrude.

Wie aus der Fig. 1 ersichtlich ist, stehen dabei die Erdungsstifte 21 weiter aus der Oberfläche des Gehäuses 15 vor als die Kontaktstifte 18. Dies bedeutet, daß damit auf einfache Weise eine voreilende und eine nacheilende Erdung beim Schalten erreicht wird.As can be seen from Fig. 1, there are the grounding pins 21 further from the surface of the housing 15 before than the contact pins 18. This means that with that easy leading and trailing grounding is reached when switching.

Die Erdungsstifte 21 befinden sich in ähnlicher Weise wie die Rückstellfedern 8 der Auslöseeinrichtung 1 in den umfangsseitigen Zwischenräumen zwischen den vier Auslösemagneten 17.The ground pins 21 are in a similar manner as the return springs 8 of the release device 1 in the peripheral Gaps between the four release magnets 17th

Wie aus der Fig. 4 ersichtlich ist, befinden sich auch die Stromzuführungskontakte 12 ebenfalls in einem Bereich zwischen der Gehäusemitte und den Schaltmagneten 5 bzw. dem Führungsring 6. Auf diese Weise wird nicht nur eine elektromechanische Verbindungsvorrichtung geschaffen, die eine geringe Bautiefe besitzt, sondern darüber hinaus auch eine Vorrichtung, die nur einen geringen Durchmesser bzw. Breite aufweist.As can be seen from Fig. 4, there are also Power supply contacts 12 also in a range between the middle of the housing and the switching magnet 5 and the Guide ring 6. This way, not just an electromechanical one Connection device created a has a shallow depth, but also one Device that is only a small diameter or width having.

Der Erdungsring 6 dient - wie erwähnt - gleichzeitig als Führungsring für die Schaltmagnete 5, wozu dieser die Schaltmagnete 5 mit einem entsprechend geringen Spiel umgibt. Auf diese Weise ist ein sicheres und verklemmungsfreies Schalten gewährleistet.The earthing ring 6 serves - as mentioned - at the same time as Guide ring for the switching magnet 5, for which this Switching magnet 5 surrounds with a correspondingly small game. This way is a safe and jam-free Switching guaranteed.

In den Fig. 5 bis 7 sind verschiedene Ausführungsbeispiele für die Schaltmagnete 5 und die Auslösemagnete 17 dargestellt.5 to 7 are different embodiments shown for the switching magnet 5 and the trigger magnet 17.

Gemäß Fig. 5 sind insgesamt nur vier Magnete auf dem Arbeitsschlitten 4 in Viertelringen angeordnet. Die Auslösemagnete 17 der Auslöseeinrichtung besitzen entsprechend an den Kreissegmenten die entgegengesetzte Polarität.5, there are a total of only four magnets on the work slide 4 arranged in quarter rings. The release magnets 17 of the release device have accordingly the opposite polarity for the circular segments.

Gemäß Fig. 6 sind jeweils ein Nord- und ein Südpol zu einem Schaltmagenten 5 zusammengefaßt. Insgesamt sind vier Schaltmagnete gleichmäßig über den Umfang verteilt angeordnet.6, a north and a south pole are each one Switching magnets 5 summarized. There are four in total Switching magnets arranged evenly distributed over the circumference.

Die beste Lösung wird mit einer Ausgestaltung gemäß Fig. 7 erreicht, die in dieser Form auch in den Fig. 1 bis 4 beschrieben ist. Hierbei besteht jede der vier Gruppen aus jeweils vier Magnetteilen 5a bis 5d. The best solution is a configuration according to FIG. 7 achieved, which are also described in this form in FIGS. 1 to 4 is. Each of the four groups consists of: four magnetic parts 5a to 5d each.

Mit der Ausgestaltung ergeben sich alternierende Nord-Süd-Kombinationen mit einer 180°-Symmetrie. Mit dieser Ausgestaltung wird ein sehr schnelles Zurückschalten des Arbeitsschlittens 4 bei einem Verdrehen der Auslöseeinrichtung 2 oder der Schalteinrichtung 1 erreicht. Aufgrund der großen Winkellängen entstehen schon bei kleinen Verdrehungen gegensinnige Felder und damit abstoßende Kräfte, wodurch der Arbeitsschlitten 4 in seine Ruhelage und damit auf Anlage zu dem Magnetring 7 zurückkehrt. Zusätzlich erlaubt die kreisförmige Ausbildung des Arbeitsschlittens 4 und auch des kreisförmigen Gehäuses 3 der Schalteinrichtung 1 und der Auslöseeinrichtung 2 eine sehr gute Kontrolle der Schaltbewegung ohne zusätzliche Führungsstifte. Damit gestaltet sich auch der geometrische Aufbau einfacher. Bei jeder Verschiebe- oder Verdrehrichtung wirken gegensinnige Magnetfelder, die damit sicher den Arbeitsschlitten 4 zurückschalten.The design results in alternating north-south combinations with a 180 ° symmetry. With this configuration becomes a very quick downshift of the work carriage 4 when the trigger device is turned 2 or the switching device 1 reached. Due to the large angular lengths arise even with small twists opposing fields and thus repulsive forces, whereby the work slide 4 in its rest position and thus returns to the magnetic ring 7. In addition allows the work slide to be circular 4 and also the circular housing 3 of the switching device 1 and the release device 2 very good control the switching movement without additional guide pins. This also makes the geometric structure easier. Act with every direction of displacement or rotation opposing magnetic fields, which thus secure the work sled 4 switch back.

In den Figuren 8 und 9 ist prinzipmäßig ein Adapter 23 dargestellt, der einen Übergang zu dem herkömmlichen elektrischen System mit Schukosteckdosen oder auch mit anderen Steckdosen ermöglicht. Hierzu besitzt der Adapter 23 entsprechend dem jeweils herkömmlichen System Stifte 24 (und gegebenenfalls noch einen Erdungsstift), die in die entsprechende Steckdose bekannter Bauart eingesteckt werden.In principle, an adapter 23 is shown in FIGS. 8 and 9 shown making a transition to the conventional electrical System with Schuko sockets or with others Sockets allows. For this purpose, the adapter 23 has accordingly the respective conventional system pins 24 (and if necessary, another earthing pin), which in the corresponding Socket of known design can be inserted.

Der Adapter 23 ist im Inneren in gleicher Weise aufgebaut wie die Auslöseeinrichtung 1, wobei lediglich die Leitungen 9 und 10 durch die Stifte 24 ersetzt sind. Aus Fig. 8 ist der Erdungsring 6 zusammen mit den beiden Kontaktstiften 14 ersichtlich. The adapter 23 is constructed in the same way on the inside as the trigger device 1, only the lines 9 and 10 are replaced by the pins 24. From Fig. 8 is the earthing ring 6 together with the two contact pins 14 can be seen.

In den Fig. 10 und 11 ist eine separate Auslöseeinrichtung 2 in Form eines Steckers 24 dargestellt, der mit zu einem Verbraucher führenden Leitungen 26 und 27 versehen ist, die in üblicher Weise mit einem Schutzmantel 25 umgeben sind. Der Stecker 24 ist im Inneren in gleicher Weise aufgebaut wie die Auslöseeinrichtung 2. Aus der Fig. 10 ist der Erdungsring 20 zusammen mit vier Erdungsstiften 21 ersichtlich.10 and 11 is a separate triggering device 2 shown in the form of a plug 24, which to a Consumer lines 26 and 27 is provided which surround in the usual way with a protective jacket 25 are. The plug 24 is constructed in the same way on the inside like the release device 2. From FIG. 10 the ground ring 20 together with four ground pins 21 evident.
