The plug connector system has a plug socket fitted with at least one single or double plug (40), for a 4-pole or 8-pole connection. The plug socket module (8) is divided into 4 chambers (32,33,34,35), each associated with a respective line wire pair of a screened cable, with a pair of pins (36) cooperating with contact sleeves (88) of the inserted plug. The chambers of the plug socket module can be positioned in a square configuration, with a single plug inserted in 2 adjacent chambers, or a double plug fitted into all 4 chambers.

Description

Die vorliegende Erfindung betrifft ein mehrpoliges Steckersystem mit einer Steckdose und mindestens einem Stecker zum elektrischen und mechanischen Verbinden von elektrischen Leitern.The present invention relates to a multi-pole plug system with a socket and at least one plug for the electrical and mechanical connection of electrical conductors.

Insbesondere ist das erfindungsgemässe Steckersystem für Gebäudeverkabelungen der Klasse E vorgesehen. Die Klasse legt die Übertragungsgüte von elektrischen Signalen von ganzen Übertragungsstrecken oder Übertragungssystemen von einem Endpunkt zu einem anderen Endpunkt fest. In entsprechenden Normen, wie EN 50173, sind beispielsweise Grenzwerte für die maximale Dämpfung für das Nebensprechen, für die Reflexionen, etc., sowie für die höchst zulässigen Frequenzen festgelegt. Für die Klasse E und zukünftige Klassen ist vorgesehen, mit Frequenzen bis zu 600 MHz und mehr zu arbeiten.In particular, the connector system according to the invention is intended for class E building cabling. The class specifies the quality of transmission of electrical signals from entire transmission links or transmission systems from one end point to another end point. Appropriate standards such as EN 50173, for example, set limits for the maximum attenuation for crosstalk, for reflections, etc., as well as for the maximum permissible frequencies. For class E and future classes it is planned to work with frequencies up to 600 MHz and more.

Es liegt im Trend des technischen Fortschrittes, Gebäudeverkabelungen in Zukunft nicht mehr getrennt für Telefon, für EDV-Anlagen, für Videoanlagen, etc. zu erstellen, sondern lediglich ein einziges Gebäudeverkabelungsnetz vorzusehen, über welches die Informationen und Daten von allen in Frage kommenden Diensten übertragen werden. Ein Anfang dazu ist mit ISDN (Integrated Service Digital Network) gemacht worden.It is in the trend of technical progress to no longer create building cabling separately for telephones, EDP systems, video systems, etc. in the future, but only to provide a single building cabling network via which the information and data can be transmitted from all relevant services will. A start has been made with ISDN (Integrated Service Digital Network).

Für Gebäudeverkabelungen für den vorgenannten Zweck werden üblicherweise abgeschirmte Kabel mit acht Adern bzw. vier Adernpaaren mit je zwei verdrillten Adern vorgesehen. Pro Dienst werden jedoch maximal vier Adern bzw. zwei Adernpaare benötigt. Bei dem heute vorzugsweise eingesetzten Steckersystem, das unter der Typenbezeichnung RJ 45 bekanntgeworden ist, ist in einer Steckdose höchstens ein Stecker für einen einzigen Dienst einsteckbar. Werden an einem Arbeitsplatz zwei Dienste benötigt, so müssen zwei Steckdosen nebeneinander montiert werden. Dies ist eine ziemlich aufwendige Arbeit, da heutzutage an den meisten Arbeitsplätzen mehr als ein einziger Dienst verlangt wird.Shielded cables with eight wires or four wire pairs with two twisted wires each are usually provided for building cabling for the aforementioned purpose. However, a maximum of four wires or two wire pairs are required per service. In the plug system which is preferably used today and has become known under the type designation RJ 45, at most one plug can be inserted into a socket for a single service. If two services are required at one workstation, two sockets must be installed side by side. This is a fairly time-consuming job because most jobs today require more than one service.

Zudem hat sich gezeigt, dass die vorgenannten elektrischen Übertragungsparameter in den Steckersystemen des Typs RJ 45 bei Frequenzen von über 300 MHz nicht geeignet sind und wünschenswerte Grössen kaum erreicht werden können. Verantwortlich dafür ist die interne Anschlusstechnik mit üblicherweise Schneid/Klemmanschlüssen, wobei die Drähte innerhalb der Steckdose oder des Steckers dieses Steckersystemes oft abgewinkelt geführt werden. Im weiteren ist bekannt, dass bei dem Steckersystem RJ 45 die Abschirmungen der einzelnen Adernpaare nicht unmittelbar bis zu den Steckkontakten geführt sind bzw. geführt werden können.In addition, it has been shown that the aforementioned electrical transmission parameters are not suitable in the RJ 45 connector systems at frequencies of more than 300 MHz and that desirable sizes can hardly be achieved. This is due to the internal connection technology with usually insulation displacement connections, whereby the wires within the socket or the plug of this plug system are often angled. Furthermore, it is known that in the RJ 45 connector system, the shields of the individual wire pairs are not or cannot be guided directly to the plug contacts.

Es ist die Aufgabe der vorliegenden Erfindung, ein gegenüber dem genannten Stand der Technik verbessertes Steckersystem vorzuschlagen. Insbesondere soll erreicht werden, dass an einer einzigen Steckdose nicht nur ein Dienst abgenommen werden kann.It is the object of the present invention to propose a connector system which is improved compared to the prior art mentioned. In particular, the aim is to ensure that not only one service can be taken from a single socket.

Ein weiteres Ziel der vorliegenden Erfindung ist es, die elektrischen Übertragungsparameter gegenüber dem bekannten Steckersystem des Typs RJ 45 zu verbessern und Übertragungsfrequenzen bis zu 600 MHz und höher zu ermöglichen. Ein zusätzliches Ziel besteht darin, für die Führung der Abschirmung innerhalb des Steckersystems, d.h. innerhalb der Steckdose und innerhalb des Steckers eine Verbesserung vorzuschlagen.Another object of the present invention is to improve the electrical transmission parameters compared to the known RJ 45 connector system and to enable transmission frequencies of up to 600 MHz and higher. An additional goal is to guide the shield within the connector system, i.e. to propose an improvement within the socket and within the plug.

Die gestellte Aufgabe wird mit einem mehrpoligen Steckersystem mit einer Steckdose und mindestens einem Stecker zum elektrischen und mechanischen Verbinden von elektrischen Leitern dadurch gelöst, dass die Steckdose ein Steckdosengehäuse umfasst, das allseitig eine metallene Oberfläche aufweist, dass das Steckdosengehäuse in mehrere einzeln nach aussen offene Kammern aufgeteilt ist, wobei in jeder der Kammern mindestens ein erster, von aussen zugänglicher Steckkontakt angeordnet ist, dass der Stecker ein Steckergehäuse umfasst, das allseitig eine metallene Oberfläche aufweist, wobei im Steckergehäuse mindestens ein zweiter von aussen zugänglicher Steckkontakt angeordnet ist, und dass pro mindestens eine Kammer ein Stecker in die Kammer der Steckdose einsteckbar ist, wobei sich der mindestens eine erste und der mindestens eine zweite Steckkontakt verbinden.The task is solved with a multi-pole plug system with a socket and at least one plug for the electrical and mechanical connection of electrical conductors in that the socket comprises a socket housing that has a metal surface on all sides, that the socket housing in several individually open chambers is divided, wherein in each of the chambers at least one first externally accessible plug contact is arranged, that the plug comprises a plug housing that has a metal surface on all sides, wherein at least one second externally accessible plug contact is arranged in the plug housing, and that at least one a chamber a plug can be inserted into the chamber of the socket, the at least one first and the at least one second plug contact connecting.

Das zweiteilige Gehäuse besteht aus einem Basisteil 2 und einer Abdeckung 3, welche beim Aufsetzen auf den Basisteil auf diesem einrastet. Dazu sind im wesentlichen am Basisteil auf den Längsseiten je eine Einrastrippe 4 und an der Abdeckung je eine federnd ausgeführte Einrastzunge 5 vorgesehen. Beim Aufsetzen der Abdeckung 3 auf den Basisteil 2 rasten die Einrastzungen über die Einrastrippen, wodurch die Abdeckung am Basisteil festgehalten wird.1 shows an embodiment of a socket 1 according to the invention. In the exploded perspective view of FIG. 1, the socket, which is comprised of a two-part socket housing 2, 3, is shown without a cable and in the open state. The two-part housing consists of a base part 2 and a cover 3, which snaps onto the base part when it is placed on it. For this purpose, a snap-in rib 4 is provided on the long sides of the base part and a snap-in tongue 5 is provided on the cover. When the cover 3 is placed on the base part 2, the latching tongues snap over the latching ribs, as a result of which the cover is held on the base part.

Die beiden Teile des Steckdosengehäuses 2, 3 sind vorzugsweise aus Kunststoff gefertigt. Insbesondere sind sie als Spritzgussteile aus einem thermoplastischen Kunststoff hergestellt. Die beiden Teile des Steckdosengehäuses sind allseitig mit einer Metallschicht überzogen. Der Überzug wird nach bekannter Art mit einem galvanischen Verfahren erstellt. Ein erster Überzug umfasst eine Kupferschicht, welche elektrisch gut leitet, und wie weiter hinten beschrieben ist, für die elektrische Verbindung eines Schirmes eines in die Steckdose eingeführten Kabels mit einem auf der Steckdosenanschlussseite angeordneten Masse- oder Erdanschluss 6, 7, bestimmt ist. Die Kupferschicht schirmt gleichzeitig das Steckdoseninnere von elektromagnetischen Feldern ab. Über der Kupferschicht ist eine vor allem als Korrosionsschutz gedachte Nickelschicht aufgebracht.The two parts of the socket housing 2, 3 are preferably made of plastic. In particular, they are made as injection molded parts from a thermoplastic. The two parts of the socket housing are coated on all sides with a metal layer. The coating is created in a known manner using a galvanic process. A first coating comprises a copper layer which conducts electricity well and, as described further below, is intended for the electrical connection of a shield of a cable inserted into the socket to a ground or earth connection 6, 7 arranged on the socket connection side. The copper layer also shields the socket interior from electromagnetic fields. A nickel layer, which is primarily intended to protect against corrosion, is applied over the copper layer.

Im Innern des Steckdosengehäuses, im Basisteil 2, ist ein Modul 8 mit Steckerpolen eingelegt. Das Modul 8 weist eine Einstecköffnung 9 auf, in welcher die Steckdosenpole zugänglich sind und beim Einstecken eines entsprechenden Steckergegenstückes mit den Steckerbuchsen des letzteren in eine elektrische Verbindung treten. Das Steckersystem ist der Klasse E zugeordnet, d.h. zum Übertragen von Frequenzen bis zu 600 MHz und mehr geeignet. Das Steckersystem ist für Kabel des Typs S/STP Kategorie 6 vorgesehen.A module 8 with plug poles is inserted in the interior of the socket housing, in the base part 2. The module 8 has an insertion opening 9, in which the socket poles are accessible and, when a corresponding connector counterpart is inserted, make an electrical connection with the sockets of the latter. The connector system is assigned to class E, i.e. suitable for transmitting frequencies up to 600 MHz and more. The connector system is intended for S / STP Category 6 cables.

Anschliessend an eine dem mit dem Stecker zu verbindenden Kabel zugewandte Stirnseite 10 des Basisteiles 2, in welcher die Kabeleinführöffnung 11 angeordnet ist, ist eine halbkreisförmige Nut 12 vorgesehen, die sich rechtwinklig zur Steckerlängsachse erstreckt. Eine gleiche halbkreisförmige Nut 13 ist anschliessend an eine dem mit der Steckdose zu verbindenden Kabel zugewandte Stirnseite 14 in der Abdeckung 3 vorhanden. Bei aufgesetzter Abdeckung 3 auf den Basisteil 2 des Steckdosengehäuses ist die Nut 12, 13 kreisförmig. In diese Nut eingesetzt ist ein Ring 15, der zum elektrischen Verbinden des Schirmes eines Kabels mit dem Masse- oder Erdanschluss 6, 7 dient. Der Ring 15 besteht vorzugsweise, wie die anderen Teile der Steckdose, aus einem metallisierten Kunststoff. Wesentlich ist, dass die mit 16 bezeichnete äussere Mantelfläche des Ringes 15 elektrisch gut leitend ist. Bei einem Kunststoffring kann dies beispielsweise mit einem Metallüberzug, ähnlich wie ein solcher vorstehend beschrieben ist, erreicht werden. Die Nut 2, 3 ist so dimensioniert, dass der Ring sowohl in seiner Längsachse als auch in der Richtung seines Durchmessers leicht Spiel hat.Adjoining an end face 10 of the base part 2 facing the cable to be connected to the plug, in which the cable insertion opening 11 is arranged, a semicircular groove 12 is provided which is at right angles extends to the longitudinal axis of the connector. An identical semicircular groove 13 is subsequently present in an end face 14 in the cover 3 facing the cable to be connected to the socket. When cover 3 is placed on base part 2 of the socket housing, groove 12, 13 is circular. Inserted into this groove is a ring 15, which serves to electrically connect the shield of a cable to the ground or ground connection 6, 7. The ring 15 is preferably, like the other parts of the socket, made of a metallized plastic. It is essential that the outer circumferential surface of the ring 15, designated by 16, is electrically well conductive. In the case of a plastic ring, this can be achieved, for example, with a metal coating, similar to that described above. The groove 2, 3 is dimensioned so that the ring has some play both in its longitudinal axis and in the direction of its diameter.

Der Modul 8 ist mit vier Kunststoffeinsätzen 17 versehen, von denen jeder zwei parallel zur Längsachse des Basisteils angeordnete zylindrische Durchgangslöcher 18 aufweist, in welche Steckerstifte zu liegen kommen. Mit dem Modul verbunden ist eine vertikale Trennwand 19 sowie eine horizontale Trennwand 20, zwischen welche je ein abgeschirmtes Paar Adern des Anschlusskabels zu liegen kommt.The module 8 is provided with four plastic inserts 17, each of which has two cylindrical through holes 18 arranged parallel to the longitudinal axis of the base part, into which plug pins come to lie. A vertical partition 19 and a horizontal partition 20 are connected to the module, between each of which a shielded pair of wires of the connecting cable comes to lie.

In Fig. 2 ist ebenfalls eine perspektivische Explosionsansicht der Steckdose, jedoch mit angeschlossenem Kabel dargestellt. Das Kabel 21, das an die Steckdose angeschlossen werden soll, umfasst mehrere Adern 22, 23, im gezeigten Beispiel acht Adern, die paarweise verdrillt innerhalb einem Kabelmantel 24 verlaufen. Je zwei verdrillte Adern sind durch einen inneren Schirm 25 abgeschirmt. Ein äusserer Schirm 26 weist eine alle Adern gesamthaft umschliessende Lage aus einem Drahtgeflecht auf. Zum Anschliessen der Steckdose 1 an das Kabel 21 wird der Mantel 24 vom Kabel in einem Endbereich entfernt. Vom Mantelende her liegen die verdrillten Adern mit der inneren Abschirmung frei. Der Ring 15 der vorgängig über den Mantel geschoben worden ist, wird nun derart angeordnet, dass er in den Bereich des Mantelendes zu liegen kommt, wobei das Drahtgeflecht des äusseren Schirmes 26 über die äussere Mantelfläche 16 des Ringes 15 gelegt wird. Die äussere Mantelfläche 16 des Ringes 15 soll möglichst über den ganzen Umfang des Ringes vom Drahtgeflecht des äusseren Schirmes 26 gleichmässig bedeckt sein. Der Ring 15 liegt mit dem darüber umgestülpten Drahtgeflecht des äusseren Schirmes 26 in der Nut 12 des Basisteiles 2. Das Spiel der Nut zum Ring ist derart, dass gerade genügend Platz zur Aufnahme des Schirmes verbleibt. Bei aufgesetzter Abdeckung 3 befindet sich der Ring 15 dann zusammen mit dem über seine äussere Mantelfläche 16 umgestülpten äusseren Schirm 26 des Kabels 21 in der umlaufenden Nut 12, 13. Der Schirm 26 liegt über den ganzen Umfang der Nut verteilt an den Stirnflächen und der Mantelfläche der Nut 12, 13 an. Der metallene Überzug des Steckdosengehäuses 2, 3 wirkt als Kontaktorgan bzw. elektrische Kontaktbahn zum Herstellen einer elektrischen Verbindung zwischen dem Ring 15, dem Schirm 26 und dem Steckergehäuse 2, 3, insbesondere den Anschlusszungen 6, 7, die für die Masse oder Erdanschlüsse auf der Aussenseite der Abdeckung 3 angeordnet sind. Durch die Nut 12, 13 wird der Ring 15 bezüglich der Längsachse der Steckdose ortsfest gehalten. Die Nut wirkt als Anschlagorgan für den Ring. Die Nut stellt also nicht nur einen elektrischen Kontakt zwischen dem Schirm und den Steckerzungen 6, 7 her, sondern ist zusammen mit dem Ring auch für die Zugentlastung des Kabels 21 verantwortlich. Die zylindrisch ausgeführten Erdanschlüsse 6, 7 sind zum Aufnehmen von Anschlusssteckern, insbesondere Rundhülsen 27 vorgesehen, an die Masse oder Erddrähte 28 angeschlossen sind. Im weiteren ist im Basisteil noch ein Einsatzteil 29 vorgesehen, der mit zwei Laschen 30 und 31 den Kontakt zwischen den inneren Schirmen 25 der Adern 22, 23 und dem Basisteil 2 herstellt.FIG. 2 also shows an exploded perspective view of the socket, but with the cable connected. The cable 21, which is to be connected to the socket, comprises a plurality of cores 22, 23, in the example shown eight cores, which are twisted in pairs within a cable sheath 24. Two twisted wires are shielded by an inner screen 25. An outer screen 26 has a layer of wire mesh that completely encloses all the wires. To connect the socket 1 to the cable 21, the jacket 24 is removed from the cable in one end region. The twisted wires with the inner shielding are exposed from the end of the jacket. The ring 15 which has previously been pushed over the jacket is now arranged in such a way that it comes to rest in the area of the jacket end, the wire mesh of the outer screen 26 being placed over the outer jacket surface 16 of the ring 15. The outer lateral surface 16 of the ring 15 should, if possible, extend over the entire circumference of the ring Wire mesh of the outer screen 26 may be covered evenly. The ring 15 lies with the wire mesh of the outer shield 26 turned over in the groove 12 of the base part 2. The play of the groove relative to the ring is such that there is just enough space to accommodate the shield. When the cover 3 is in place, the ring 15 is then located in the circumferential groove 12, 13 together with the outer shield 26 of the cable 21 which is turned over its outer circumferential surface 16. The shield 26 is distributed over the entire circumference of the groove on the end faces and the circumferential surface the groove 12, 13. The metal coating of the socket housing 2, 3 acts as a contact element or electrical contact path for establishing an electrical connection between the ring 15, the shield 26 and the connector housing 2, 3, in particular the connecting tongues 6, 7, which are used for the ground or earth connections on the Outside of the cover 3 are arranged. Through the groove 12, 13, the ring 15 is held stationary with respect to the longitudinal axis of the socket. The groove acts as a stop element for the ring. The groove thus not only makes electrical contact between the shield and the plug tongues 6, 7, but together with the ring is also responsible for the strain relief of the cable 21. The cylindrical earth connections 6, 7 are provided for receiving connection plugs, in particular round sleeves 27, to which earth or earth wires 28 are connected. Furthermore, an insert 29 is provided in the base part, which uses two tabs 30 and 31 to make contact between the inner shields 25 of the wires 22, 23 and the base part 2.

In Fig. 3 ist die Steckdose in perspektivischer Ansicht dargestellt. Das Modul 8 der Steckdose weist vier Kammern 32, 33, 34 und 35 auf, wobei pro Kammer ein Adernpaar des paarweise geschirmten Kabels 21 aufgenommen werden kann. Pro Kammer des Moduls 8 werden, wie weiter unten noch beschrieben wird, je zwei Steckerstifte 36 montiert. Die inneren Kammerwandungen 90 dienen zur Herstellung des Kontaktes mit dem Stecker.In Fig. 3 the socket is shown in perspective. The module 8 of the socket has four chambers 32, 33, 34 and 35, with one pair of wires of the cable 21 shielded in pairs being able to be accommodated per chamber. As described further below, two connector pins 36 are installed per chamber of module 8. The inner chamber walls 90 are used to make contact with the plug.

In Fig. 4 ist die Steckdose in perspektivischer Ansicht von der Rückseite aus gesehen dargestellt.In Fig. 4, the socket is shown in perspective view seen from the rear.

In Fig. 5 ist ein perspektivische Explosionsansicht der Steckdose von der Vorderseite aus gesehen dargestellt. In die vier Kammern 32, 33, 34 und 35 des Modules 8 werden vier Kunststoffeinsätze 17 eingefügt. Die Kunststoffeinsätze weisen auf einer Diagonalen je zwei Durchgangslöcher 18 auf. In die Durchgangslöcher 18 werden Steckerstifte 36 eingesetzt, auf deren Rückseite die acht Adern des Kabels angeschlossen werden. Die Anordnung der je zwei Steckerstiften in den vier Kammern ist so, dass gleichzeitig ein Verpolungsschutz erreicht wird. Der Stecker eines Dienstes kann nur in einer einzigen Position eingesteckt werden. Der Einsatzteil 29 dient einerseits zur Herstellung des Kontaktes von den inneren Schirmen auf das Gehäuse, andererseits zur Arretierung des Moduls 8 im Basisteil 2. Diese Arretierung geschieht durch eine Stufe 37 im Boden 38 des Einsatzteiles 29. Bei der zusammengesetzten Steckdose greift eine Aussparung an der unteren Kante der vertikalen Trennwand 19 in einen Nocken 39 am Einsatzteil 29 ein.5 shows an exploded perspective view of the socket seen from the front. Four plastic inserts 17 are inserted into the four chambers 32, 33, 34 and 35 of the module 8. The plastic inserts each have two through holes 18 on a diagonal. In the through holes 18 connector pins 36 are inserted, on the back of which the eight wires of the cable are connected. The arrangement of the two connector pins in the four chambers is such that reverse polarity protection is achieved at the same time. The plug of a service can only be inserted in one position. The insert part 29 serves on the one hand to make contact from the inner shields to the housing, and on the other hand to lock the module 8 in the base part 2. This locking takes place by a step 37 in the bottom 38 of the insert part 29. In the assembled socket, a recess engages in the lower edge of the vertical partition 19 into a cam 39 on the insert part 29.

Beim erfindungsgemässen Steckersystem können wahlweise ein oder zwei Dienste angeschaltet werden, wobei pro Dienst zwei oder vier Adernpaare des achtadrigen Kabels der Steckdose verwendet werden. Für einen oder zwei Dienste mit zwei Adernpaaren werden ein oder zwei Einfachstecker 40 und für einen Dienst mit vier Adernpaaren ein Doppelstecker 48 verwendet. Beim erfindungsgemässen Steckersystem ist die Erdung ununterbrochen durchgeführt. Ein durch die ganze Steckdose oder den ganzen Stecker durchgeführter Schirm verhindert bei hohen Frequenzen ein Neben- oder Übersprechen. Das Steckersystem ist als Vierkammersystem mit vier metallisierten Kammern 32, 33, 34, 35 gebildet, wobei pro Kammer ein Adernpaar 22, 23, 68, 76 des paarweise geschirmten Kabels aufgenommen werden kann. Durch diese Konstruktion und durch die durchgeführte Erdung ist das Steckersystem EMV-dicht. Wegen den hohen Frequenzen ist das Anschlusssystem radial mit Tulpenkontakten ausgeführt. Es wird dadurch ein gerader Durchgang der Leiter durch das Steckersystem erreicht, was sich günstig auf die Dämpfung auswirkt. In der Steckerdose 1 sind entgegen der allgemein üblichen Norm die Steckerstifte 36 angeordnet und im Stecker 40, 48 sind die Steckerbuchsen 88, 89 untergebracht. Durch diese vertauschte Anordnung wird ein besserer Schutz der Kontaktstifte erreicht. Die Anordnung der je zwei Kontaktstifte in den vier Kammern auf einer Diagonalen ist so, dass gleichzeitig ein Verpolungsschutz erreicht wird. Der Stecker eines Dienstes kann nur in einer einzigen Position eingesteckt werden.In the connector system according to the invention, one or two services can optionally be switched on, two or four wire pairs of the eight-wire cable of the socket being used for each service. One or two single plugs 40 are used for one or two services with two wire pairs and a double plug 48 for a service with four wire pairs. In the connector system according to the invention, the earthing is carried out continuously. One through the whole outlet or the whole The connector shield prevents crosstalk or crosstalk at high frequencies. The plug system is designed as a four-chamber system with four metallized chambers 32, 33, 34, 35, one pair of wires 22, 23, 68, 76 of the pair-shielded cable being able to be accommodated per chamber. This construction and the grounding performed make the connector system EMC-tight. Because of the high frequencies, the connection system is designed radially with tulip contacts. A straight passage of the conductors through the plug system is thereby achieved, which has a favorable effect on the damping. Contrary to the generally accepted norm, the plug pins 36 are arranged in the socket 1 and the plug sockets 88, 89 are accommodated in the plug 40, 48. This reversed arrangement provides better protection for the contact pins. The arrangement of the two contact pins in the four chambers on a diagonal is such that reverse polarity protection is achieved at the same time.
