Description

Die Erfindung bezieht sich auf einen Verbinder für zwei elektrische Energiekabel. Der Verbinder weist einen Stecker und eine Buchse auf, in welche jeweils ein Leiter der Kabel einführbar ist und die geeignet sind, einen lösbaren elektrischen Kontakt zwischen den Leitern herzustellen. Die Buchse hat eine in Längsrichtung verlaufende Aushöhlung und der Stecker einen in Längsrichtung abstehenden Bolzen, der in die Aushöhlung eingesteckt werden kann.The invention relates to a connector for two electrical power cables. The connector has a plug and a socket, into each of which a conductor of the cable is insertable and which are adapted to produce a releasable electrical contact between the conductors. The socket has a longitudinal cavity and the plug has a longitudinally extending pin that can be inserted into the cavity.

Die im Folgenden beschriebenen Metalle für Leiter oder Teile des Verbinders sollen auch die entsprechenden Metallegierungen umfassen.The metals for conductors or parts of the connector described below are also intended to include the corresponding metal alloys.

Bekannte Verbinder für elektrische Energiekabel, die aus zwei Verbinderteilen bestehen, die mit jeweils einem Leiterende kontaktiert sind, können verschiedene Formen aufweisen, von denen im Folgenden einige Beispiele genannt sind.Known connectors for electric power cables, which consist of two connector parts, which are each contacted with a conductor end, may have various shapes, of which some examples are given below.

Die Verbinderteile können beispielsweise jeweils an einem Ende eine Verlängerung mit einer flachen Kontaktfläche aufweisen. Diese Kontaktflächen werden aufeinandergelegt und mit einer Schraube verbunden, um die elektrische Verbindung zwischen den beiden Verbinderteilen herzustellen. Um einen einwandfreien elektrischen Kontakt zu gewährleisten, müssen die Kontaktflächen aufwendig hergestellt und mit viel Kraftaufwand fest miteinander verbunden werden.For example, the connector parts may each have an extension with a flat contact surface at one end. These contact surfaces are superimposed and connected with a screw to make the electrical connection between the two connector parts. To ensure proper electrical contact, the contact surfaces must be made consuming and firmly connected with much effort.

Nach einem weiteren Beispiel kann der Verbinder als Steckverbinder ausgeführt sein und aus einer Buchse und einem Stift oder Stecker, welcher in eine Aushöhlung der Buchse eingesteckt werden kann, bestehen. Die Buchse ist an ihrer Kontaktfläche mit dem Stecker mit Kontaktelementen versehen, die den elektrischen Kontakt durch eine Vielzahl von einzelnen Kontaktpunkten zwischen Stift und Buchse herstellen. Es kann auch der Stecker mit derartigen Kontaktelementen ausgerüstet sein. Die Kontaktelemente können beispielsweise aus Kontaktlamellen oder Kontaktfedern bestehen. Sie werden aus Kupfer gefertigt und sind versilbert, vergoldet oder vernickelt. Die Verwendung solcher Kontaktelemente in einem Verbinder ist durch deren Herstellung und Montage in der Buchse oder am Stecker mit erheblichem Mehraufwand an Material, Arbeitszeit und dementsprechenden Kosten verbunden.As another example, the connector may be a connector and may consist of a socket and a pin or plug which may be inserted into a socket cavity. The socket is provided at its contact surface with the plug with contact elements which make the electrical contact through a plurality of individual contact points between the pin and socket. It can also be equipped with such contact elements of the plug. The contact elements may for example consist of contact blades or contact springs. They are made of copper and are silver plated, gold plated or nickel plated. The Use of such contact elements in a connector is associated with their production and assembly in the socket or on the plug with considerable overhead of material, labor and related costs.

Die US 3 372 476 A beschreibt einen Verbinder für elektrische Kabel, dessen Stecker und Buchsenöffnung jeweils eine konische Form haben. Der Stecker wird mit einem Werkzeug in die Buchse hineingeschlagen. Der Stecker ist mit einer dünnen Schicht aus Indium versehen, was dazu führt, dass die Verbindung nach einer bestimmten Zeit permanent wird.The US 3,372,476 A. describes a connector for electrical cables whose plug and socket opening each have a conical shape. The plug is knocked into the socket with a tool. The plug is provided with a thin layer of indium, which causes the connection to become permanent after a certain time.

Die US 2 308 811 A beschreibt einen elektrischen Kabelverbinder, bei welchem der Stecker und die Öffnung der Buchse eine konische Form haben. Die beiden Teile halten dank der Reibungskräfte zusammen.The US 2 308 811 A describes an electrical cable connector in which the plug and the opening of the socket have a conical shape. The two parts hold together thanks to the friction forces.

Die DE 10 2010 045 921 A1 offenbart ein Verbindungssystem mit zwei komplementären Verbindungsstücken, welche jeweils eine konische Form aufweisen. Ein Verbindungsstück ist durch Selbsthemmung im anderen gehalten.The DE 10 2010 045 921 A1 discloses a connection system with two complementary connectors, each having a conical shape. One connector is held in the other by self-locking.

Der Erfindung liegt die Aufgabe zugrunde, einen Verbinder für elektrische Energiekabel bereitzustellen, welcher einfach aufgebaut ist, dessen Verbinderteile ohne Kraftaufwand verbunden werden können und welcher einen einwandfreien elektrischen Kontakt ermöglicht.The invention has for its object to provide a connector for electrical power cables, which is simple in construction, the connector parts can be connected without effort and which allows proper electrical contact.

Diese Aufgabe wird durch einen Verbinder nach Anspruch 1 gelöst. Gemäß der Erfindung haben die Aushöhlung der Buchse und der Bolzen des Steckers zueinander identische Kegelstumpfformen, sodaß der Bolzen in der Aushöhlung durch Selbsthemmung in einer Arbeitsstellung feststellbar ist.This object is achieved by a connector according to claim 1. According to the invention, the cavity of the socket and the pin of the plug have mutually identical truncated cone shapes, so that the pin is detectable in the hollow by self-locking in a working position.

Der erfindungsgemäße Verbinder erlaubt ein schnelles und leichtes Verbinden zweier elektrischer Energiekabel, bei dem keine speziellen Werkzeuge benötigt werden. Durch die identischen, kegelstumpfartigen Formen von Aushöhlung und Bolzen entsteht in Arbeitsstellung, wenn Buchse und Stecker zusammengesteckt sind, eine Selbsthemmung, sodaß es zu einer festen, lösbaren Verbindung der zwei Verbinderteile kommt. Die Selbsthemmung wird durch Haftreibung zwischen den genau aufeinander abgestimmten Kegelstumpfmantelflächen von Bolzen und Aushöhlung erzeugt. Durch die Oberflächenrauhigkeit der beiden Mantelflächen läßt sich die Stärke der Selbsthemmung beeinflussen. Die Selbsthemmung sorgt dafür, daß der Verbinder in Arbeitsposition verbleibt, solange keine der Selbsthemmung entgegenwirkende Kraft, beispielsweise eine Zugkraft, auf die Verbinderteile einwirkt. Die Verbindung der Kabel ist lösbar, sodaß jedes der beiden Kabel bei Bedarf mit einem anderen, weiteren Kabel verbunden werden kann. Der erfindungsgemäße Verbinder ist außerdem besonders kostengünstig.The connector according to the invention allows a quick and easy connection of two electrical power cables, in which no special tools are needed. Due to the identical, frustoconical shapes of cavity and bolt arises in working position when socket and plug are plugged together, a self-locking, so that there is a solid, detachable connection of the two connector parts. The self-locking is generated by static friction between the precisely matched truncated cone lateral surfaces of bolt and cavity. Due to the surface roughness of the two lateral surfaces, the strength of the self-locking can be influenced. The self-locking ensures that the connector remains in working position as long as no self-locking counteracting force, such as a pulling force, on the connector parts acts. The connection of the cable is detachable, so that each of the two cables can be connected with another, further cable if necessary. The connector according to the invention is also particularly inexpensive.

Des weiteren ist der erfindungsgemäße Verbinder mit einem Verriegelungsmittel ausgerüstet. Hierbei handelt es sich um einen Stift, der so angeordnet ist, dass seine Achse rechtwinklig zu einer Verbindungsachse des Verbinders ist, und der mit einer um den Durchmesser des Bolzens umlaufenden Vertiefung zusammenwirkt.Furthermore, the connector according to the invention is equipped with a locking means. This is a pin which is arranged so that its axis is perpendicular to a connection axis of the connector, and which cooperates with a circumferential around the diameter of the bolt recess.

Dadurch wird sichergestellt, daß der Verbinder auch beim Angreifen einer Zugkraft zuverlässig in Arbeitsstellung verbleibt.This ensures that the connector remains reliably in working position even when engaging a tensile force.

Der Verbinder gemäß der Erfindung eignet sich mit Vorteil für die Verbindung von Kabeln gleichen Materials oder beispielsweise von Kupfer- mit Aluminiumleitungen im Nieder- und Mittelspannungsbereich. Sie sind deshalb beispielsweise geeignet für den Einsatz in Windkraftanlagen, um Aluminiumkabel der Turmsegmente miteinander zu verbinden und den Übergang zu den Kupferleitungen in der Gondel und im Fundament herzustellen.The connector according to the invention is advantageously suitable for the connection of cables of the same material or, for example, copper and aluminum cables in the low and medium voltage range. They are therefore suitable, for example, for use in wind turbines to connect aluminum cables of the tower segments together and to make the transition to the copper pipes in the nacelle and in the foundation.

Der erfindungsgemäße Verbinder kann alternativ auch dazu dienen, ein elektrisches Kabel an ein elektrisches Gerät anzustecken. Dafür ist beispielsweise die Buchse fest mechanisch und elektrisch mit dem Gerät verbunden, sodaß der mit dem Kabel verbundene Stecker schnell und einfach mit dem Gerät verbunden werden kann.The connector according to the invention may alternatively serve to connect an electrical cable to an electrical device. For example, the socket is fixed mechanically and electrically connected to the device, so that the plug connected to the cable can be quickly and easily connected to the device.

In Fig. 1A ist ein Verbinder 1 ohne Verriegelungsmittel in einer Seitenansicht und in offener Position dargestellt. Fig. 1B zeigt denselben Verbinder 1 in einem Längsschnitt und in Arbeitsstellung, d.h. in geschlossener Position. Der Verbinder 1 umfaßt einen Stecker 2 und eine Buchse 3. Der Stecker 2 und die Buchse 3 haben jeweils eine Öffnung 4, 5 entlang ihrer Hauptachse, in welche jeweils ein abisolierter Leiter eines Kabels (nicht dargestellt) eingeführt werden kann, sodaß dieser fest mit dem jeweiligen Verbinderteil 2, 3 verbunden werden kann. In Arbeitsstellung sind die Hauptachsen des Steckers 2 und der Buchse 3 parallel und fallen mit der Haupt- bzw. Verbindungsachse 10 des Verbinders 1 zusammen. In dem dargestellten Beispiel werden die Leiterenden der Kabel mittels Schrauben in dem Stecker 2 bzw. der Buchse 3 angeschraubt. Dafür haben jeweils der Stecker 2 und die Buchse 3 zwei mit einem Innengewinde versehene Schraubenlöcher 6, 7, 8, 9. Die jeweilige Anzahl der Schraubenlöcher richtet sich nach der Art und dem Einsatzgebiet des Verbinders. Die verwendeten Schrauben sind vorzugsweise Scherschrauben, sodaß die jeweils überstehenden Teile der Schrauben nach dem Festschrauben der Leiter abgebrochen werden können und man eine gleichmäßig rohrförmige Verbinderoberfläche erhält. Die Öffnungen 4, 5 des Steckers 2 und der Buchse 3, in welche die abisolierten Leiterenden eingeführt werden, weisen jeweils ring- oder spiralförmig angeordnete, spitz zulaufende Vorsprünge 13, 14 auf, die eventuell vorhandene Oxidschichten auf den abisolierten Leitern aufbrechen und so den elektrischen Widerstand zwischen Leitern und Verbinderteilen 2, 3 verringern. Die abisolierten Leiter können auch auf andere bekannte Weise mit den Verbinderteilen verbunden werden, beispielsweise durch Crimpen (Preßverbindung).In Fig. 1A a connector 1 is shown without locking means in a side view and in the open position. Fig. 1B shows the same connector 1 in a longitudinal section and in working position, ie in the closed position. The connector 1 comprises a plug 2 and a socket 3. The plug 2 and the socket 3 each have an opening 4, 5 along its main axis, in each of which a stripped conductor of a cable (not shown) can be inserted so that it firmly with the respective connector part 2, 3 can be connected. In working position, the main axes of the plug 2 and the socket 3 are parallel and coincide with the main or connecting axis 10 of the connector 1 together. In the example shown, the conductor ends of the cables are screwed by means of screws in the plug 2 and the socket 3. For this purpose, each of the plug 2 and the socket 3 have two screw holes 6, 7, 8, 9 provided with an internal thread. The respective number of screw holes depends on the type and field of application of the connector. The screws used are preferably shear screws, so that the respective protruding parts of the screws can be broken off after screwing the conductor and you get a uniformly tubular connector surface. The openings 4, 5 of the plug 2 and the socket 3, in which the stripped conductor ends are inserted, each have ring-shaped or spirally arranged, tapered projections 13, 14, which break up any existing oxide layers on the stripped conductors and so the electrical Reduce resistance between conductors and connector parts 2, 3. The stripped conductors can also be connected in other known manner with the connector parts, for example by crimping (press connection).

Der Stecker 2 hat einen in Längsrichtung abstehenden, der Hauptachse 10 des Verbinders 1 folgenden Bolzen 11. Die Buchse 3 hat eine in Längsrichtung, der Hauptachse 10 folgenden Aushöhlung 12. Der Bolzen 11 ist in die Aushöhlung 12 einsteckbar, sodaß ein lösbarer elektrischer Kontakt zwischen den Leitern hergestellt werden kann. Die beiden Verbinderteile 2, 3 bestehen beispielweise aus Kupfer oder Aluminium. Die Verbinderteile 2, 3 bestehen vorzugsweise aus reinem Kupfer oder reinem Aluminium, wenn diese jeweils mit den Leitern durch Crimpen verbunden werden sollen. Wird zum Verbinden der Leiter mit den Verbinderteilen 2, 3 die oben erwähnte Schraubtechnik verwendet, so bestehen die Verbinderteile 2, 3 vorzugsweise aus Messing oder aus einer Aluminiumlegierung, da diese Materialien eine größere Härte als reines Kupfer oder Aluminium aufweisen. Je nach Anwendung des Verbinders können beide Verbinderteile 2, 3 dabei aus demselben Metall oder aus verschiedenen Metallen bestehen.The plug 2 has a longitudinally projecting, the main axis 10 of the connector 1 following bolt 11. The sleeve 3 has a longitudinal direction, the main axis 10 following hollow 12. The bolt 11 is inserted into the cavity 12, so that a releasable electrical contact between the ladders can be made. The two connector parts 2, 3 consist for example of copper or aluminum. The connector parts 2, 3 are preferably made of pure copper or pure aluminum, if they are to be connected to the conductors by crimping. If the abovementioned screwing technique is used to connect the conductors to the connector parts 2, 3, the connector parts 2, 3 are preferably made of brass or of an aluminum alloy, since these materials have a greater hardness than pure copper or aluminum. Depending on the application of the connector, both connector parts 2, 3 can consist of the same metal or different metals.

Gemäß der Erfindung haben der Bolzen 11 und die Aushöhlung 12 zueinander identische Kegelstumpfformen, sodaß der Bolzen 11 in der Aushöhlung 12 durch Selbsthemmung in der Arbeitsstellung festgestellt werden kann. Die Selbsthemmung kann beispielsweise durch an den Verbinderteilen 2, 3 angreifende Zugkräfte aufgehoben werden. Ohne eine solche Zugbelastung verbleibt der Verbinder 1 sicher in Arbeitsstellung. In Arbeitsposition des Verbinders 1 überlappen sich der Bolzen 11 und die Aushöhlung 12 vollständig.According to the invention, the bolt 11 and the cavity 12 have mutually identical truncated cone shapes, so that the bolt 11 can be detected in the cavity 12 by self-locking in the working position. The self-locking can be canceled for example by acting on the connector parts 2, 3 tensile forces. Without such a tensile load, the connector 1 remains securely in working position. In the working position of the connector 1, the pin 11 and the cavity 12 completely overlap.

Der erfindungsgemäße Verbinder kann in Arbeitsstellung beispielweise ca. 140 mm bis 260 mm lang sein und elektrische Energiekabel mit Querschnittsflächen im Bereich von ca. 95 mm2 bis 500 mm2 miteinander verbinden.The connector according to the invention can be in the working position, for example, about 140 mm to 260 mm long and connect electrical power cables with cross-sectional areas in the range of about 95 mm 2 to 500 mm 2 together.

Fig. 2 zeigt einen Ausschnitt aus dem Überlappungsbereich des Verbinders in Arbeitsstellung, bei welchem der Bolzen 11 in die Aushöhlung 12 eingesteckt ist. In Fig. 2 sind die Mantellinie 10' und die Kegelachse der Kegelstumpfform, welche mit der Hauptachse 10 des Verbinders zusammenfällt, dargestellt. Die Kegelstumpfformen von Bolzen 11 und Aushöhlung 12 sind identisch, sodaß sie in Arbeitsstellung eine gemeinsame Mantellinie 10' und eine gemeinsame Kegelachse 10 haben. Der Winkel α zwischen der Kegelachse 10 und der Mantellinie 10' hat mit Vorteil einen Wert zwischen 0,2° und 10°. Dadurch wird eine ausreichende Selbsthemmung gewährleistet, und gleichzeitig läßt sich die Steckverbindung einfach herstellen. Der Kegelstumpf entspricht vorzugsweise einem Morsekegel nach DIN 228 und der Winkel α dem Neigungswinkel des Morsekegels. Fig. 2 shows a section of the overlap region of the connector in the working position, in which the bolt 11 is inserted into the cavity 12. In Fig. 2 For example, the generatrix 10 'and the cone axis of the truncated cone shape which coincides with the major axis 10 of the connector are shown. The truncated cone shapes of bolt 11 and cavity 12 are identical, so that they have a common surface line 10 'and a common cone axis 10 in the working position. The angle α between the cone axis 10 and the generatrix 10 'advantageously has a value between 0.2 ° and 10 °. This ensures sufficient self-locking, and at the same time, the connector can be easily made. The truncated cone preferably corresponds to a Morse taper according to DIN 228 and the angle α to the angle of inclination of the Morse taper.

Um den erfindungsgemäßen Verbinder 1, zusätzlich zur Selbsthemmung, in Arbeitsstellung zu halten und um ihn auch in zugbelasteten Energiekabelverbindungen einsetzten zu können, kann dieser mit Vorteil ein Verriegelungsmittel umfassen. In Verbindung mit den in den Fig. 3A bis 5B dargestellten erfindungsgemäßen Verbindern 1 werden Beispiele von verschiedenen Verriegelungsmitteln erläutert. Die Verbinder 1 nach diesen weiteren Ausführungsformen sind baugleich mit dem Verbinder 1 nach der ersten Ausführungsform, mit dem zusätzlichen Merkmal des jeweiligen Verriegelungsmittels.In order to keep the connector 1 according to the invention, in addition to the self-locking, in working position and to use it also in zugbelasteten power cable connections, this can advantageously comprise a locking means. In conjunction with the in the Figs. 3A to 5B illustrated connectors 1 according to the invention examples of different locking means are explained. The connectors 1 according to these further embodiments are identical in construction to the connector 1 according to the first embodiment, with the additional feature of the respective locking means.

In Fig. 3A ist ein Verbinder 1 gemäß einer ersten bevorzugten Ausführungsform in einer Seitenansicht und in Arbeitsstellung dargestellt. Fig. 3B zeigt denselben Verbinder 1 in einem Längsschnitt und ebenfalls in Arbeitsposition. In diesem Beispiel besteht das Verriegelungsmittel aus einer Schraube 15, die in Arbeitsposition in eine dafür vorgesehene Öffnung 16 in der Wand der Buchse 3 auf der Höhe der Aushöhlung 12 geschraubt wird. Die Achse der Öffnung 16 schneidet die Hauptachse 10 des Verbinders 1 senkrecht. Die Schraube 15 wirkt mit einer um den Durchmesser des Bolzens 11 umlaufenden Vertiefung 17, beispielweise einer Nut, zusammen. Durch das Anbringen der Schraube 15 in Arbeitsstellung wird ein ungewolltes Herausziehen des Steckers 2 aus der Buchse 3 verhindert. Gleichzeitig kann mittels der Schraube 15 zusätzlich Kontaktdruck zwischen den beiden Kegelstumpfmantelflächen von Bolzen 11 und Aushöhlung 12 erzeugt werden.In Fig. 3A a connector 1 according to a first preferred embodiment is shown in a side view and in working position. Fig. 3B shows the same connector 1 in a longitudinal section and also in working position. In this example, the locking means consists of a screw 15, which is screwed into working position in a designated opening 16 in the wall of the socket 3 at the height of the cavity 12. The axis of the opening 16 intersects the main axis 10 of the connector 1 vertically. The screw 15 cooperates with a circumferential around the diameter of the pin 11 recess 17, for example, a groove together. By attaching the screw 15 in the working position unintentional removal of the plug 2 from the socket 3 is prevented. At the same time by means of the screw 15 additional contact pressure between the two truncated cone lateral surfaces of pin 11 and cavity 12 can be generated.

In Fig. 4A ist ein Verbinder 1 gemäß einer zweiten bevorzugten Ausführungsform in einer Seitenansicht und in offener Position dargestellt. Fig. 3B zeigt denselben Verbinder 1 in einem Längsschnitt und in Arbeitsstellung. Fig. 4C zeigt einen Querschnitt des Verbinders 1 entlang der in Fig. 4B eingezeichneten Schnittlinie A-A. Das Verriegelungsmittel umfaßt hier einen Stift 18, der in Arbeitsposition in eine dafür vorgesehene Öffnung 19 in der Wand der Buchse 3 auf der Höhe der Aushöhlung 12 gepreßt wird. Die Achse der Öffnung 19 ist senkrecht zu der Hauptachse 10 des Verbinders 1, schneidet diese aber nicht, d.h. die Achse der Öffnung 19 bildet eine Sekante für den von der Buchsenwand im Querschnitt beschriebenen Kreis. Der Stift 18 wirkt mit einer um den Durchmesser des Bolzens 11 umlaufenden Vertiefung 20, beispielweise einer Nut, zusammen. Der Stift 18 gleitet dabei seitlich in die umlaufende Nut 20, wie aus den Fig. 4B und 4C hervorgeht. Durch das Anbringen des Stifts 18 in Arbeitsstellung wird ein ungewolltes Herausziehen des Steckers 2 aus der Buchse 3 verhindert. Die Verriegelung mit einem Stift stellt eine günstige Alternative gegenüber der Verriegelung mit einer Schraube dar und benötigt keine zusätzlichen Werkzeuge.In Fig. 4A a connector 1 according to a second preferred embodiment is shown in a side view and in the open position. Fig. 3B shows the same connector 1 in a longitudinal section and in working position. Fig. 4C shows a cross section of the connector 1 along in FIG Fig. 4B drawn section line AA. The locking means here comprises a pin 18 which is pressed into the working position in a designated opening 19 in the wall of the socket 3 at the height of the cavity 12. The axis of the opening 19 is perpendicular to the main axis 10 of the connector 1, but does not intersect it, ie the axis of the opening 19 forms a secant for the circle described by the bushing wall in cross-section. The pen 18 acts with a circumferential around the diameter of the pin 11 recess 20, for example, a groove together. The pin 18 slides while the side into the circumferential groove 20, as from the Figs. 4B and 4C evident. By attaching the pin 18 in the working position unintentional pulling out of the plug 2 from the socket 3 is prevented. The locking with a pin represents a favorable alternative to the locking with a screw and requires no additional tools.

In Fig. 5A ist eine Seitenansicht eines Verbinders 1 wiederum ohne Verriegelungsmittel in Arbeitsstellung dargestellt. Fig. 5B zeigt denselben Verbinder 1 in einem Längsschnitt und ebenfalls in Arbeitsposition. In dieser Ausführungsform besteht das Verriegelungsmittel aus einer Schale 21. Die Schale 21 besteht vorzugsweise aus Kunststoff. Die Schale 21 weist an ihrer inneren Oberfläche zwei rechtwinklig zu der Hauptachse 10 des Verbinders vorstehende Vorsprünge 24, 25, beispielsweise Nutfedern, auf, welche in je eine Vertiefung 26, 27, beispielsweise eine Nut, der Buchse und des Steckers einfügbar sind. In dem gezeigten Beispiel sind die Nutfedern und die Nuten jeweils um den Innendurchmesser der Schale 21 und den Außendurchmesser des Steckers 2 bzw. der Buchse 3 umlaufend. Die Schale 21 kann, wie in Fig. 5A dargestellt, beispielweise aus zwei Hälften 22, 23 bestehen, welche in Längsrichtung des Verbinders 1 in der Arbeitsstellung zusammengefügt werden und welche beispielsweise mit einem Filmscharnier miteinander verbunden sind. In Fig. 5A ist die Schale 21 offen dargestellt. Alternativ kann die Schale auch aus zwei Hälften bestehen, wobei je eine Hälfte bereits an der Buchse 3 und dem Stecker 2 angebracht ist. Wird der Verbinder 1 in Arbeitsposition gebracht, wird gleichzeitig die Schale geschlossen. In beiden Fällen läßt sich die Schale 21 beispielsweise mittels eines Rastmechanismus schließen.In Fig. 5A is a side view of a connector 1 again shown without locking means in working position. Fig. 5B shows the same connector 1 in a longitudinal section and also in working position. In this embodiment, the locking means consists of a shell 21. The shell 21 is preferably made of plastic. The shell 21 has on its inner surface two at right angles to the main axis 10 of the connector projecting projections 24, 25, for example, tongue springs, which in each case a recess 26, 27, for example, a groove, the socket and the plug can be inserted. In the example shown, the groove springs and the grooves in each case around the inner diameter of the shell 21 and the outer diameter of the plug 2 and the sleeve 3 are circumferential. The shell 21 can, as in Fig. 5A represented, for example, consist of two halves 22, 23, which are joined together in the longitudinal direction of the connector 1 in the working position and which are connected to each other, for example with a film hinge. In Fig. 5A the shell 21 is shown open. Alternatively, the shell can also consist of two halves, with one half each already attached to the socket 3 and the plug 2. If the connector 1 is brought into working position, the shell is closed at the same time. In both cases, the shell 21 can be closed, for example by means of a latching mechanism.

Eine solche Schale läßt sich ohne zusätzliche Werkzeuge installieren und verhindert ein ungewolltes Herausziehen des Steckers 2 aus der Buchse 3 in Arbeitsstellung. Die Verriegelung mittels Kunststoffschale bietet außerdem einen Berührungsschutz nach der Schutzart IP2X (nach EN 60529).Such a shell can be installed without additional tools and prevents accidental removal of the plug 2 from the socket 3 in working position. The locking by means of a plastic shell also offers protection against contact according to protection class IP2X (according to EN 60529).

Eine Verbindung gemäß der Erfindung umfaßt den beschriebenen erfindungsgemäßen Verbinder 1 sowie einen Rollschlauch (nicht dargestellt). Der Rollschlauch ist, solange der Verbinder in offener Position ist, auf einem der beiden Kabel angeordnet. Nachdem der Verbinder 1 in Arbeitsstellung gebracht wurde, wird der Rollschlauch so auf den Verbinder 1 aufgerollt, daß der Rollschlauch von der Isolierung des einen bis über die Isolierung des anderen Kabels reicht. Dadurch werden alle Metallteile an und um den Verbinder 1 abgedeckt, wodurch der Verbinder elektrisch isoliert und vor mechanischen Umwelteinflüssen zuverlässig geschützt ist. Der Rollschlauch besteht beispielsweise aus einem Gummiwerkstoff. Eine solche Verbindung läßt sich besonders schnell und einfach herstellen.A compound according to the invention comprises the described connector 1 according to the invention and a rolling hose (not shown). The roll tube is placed on one of the two cables as long as the connector is in the open position. After the connector 1 has been brought into the working position, the rolling hose is rolled onto the connector 1 so that the rolling hose extends from the insulation of one to the insulation of the other cable. As a result, all metal parts are covered on and around the connector 1, whereby the connector is electrically insulated and reliably protected against mechanical environmental influences. The rolling tube consists for example of a rubber material. Such a connection can be made particularly quickly and easily.
