Sie dienen der elektrischen Verbindung zwischen einem Gehäuse der Zündschutzart Druckfeste Kapselung "d" und einem Gehäuse der Zündschutzart Erhöhte Sicherheit "e".The wire entries shown in the drawing are intended for use in potentially explosive atmospheres and designed in accordance with the requirements of DIN EN 50014, 50018, 50019 and DIN EN 60079-0, 60079-1, 60079-7. They are used for the electrical connection between a housing of type of protection Flameproof Enclosure "d" and a housing of type of protection Increased Safety "e".

Die Aderleitungseinführung 1 der FIG. 1 und 2 weist eine bezüglich einer Achse 2 kreisringförmige Montagehülse 3 auf, die bevorzugt aus einem elektrisch isolierenden Kunststoffmaterial hergestellt ist, und besitzt am äußeren Umfang einen materialeinheitlich angeformten Bund 4. Die Montagehülse 3 kann an einer Montagewand 5 montiert werden und diese durchsetzen, wobei der Bund 4 zweckmäßig an der dem Raum "d" zugewandten Seite der Montagewand 5 anliegt. Die Befestigung der Montagehülse 3 kann mittels einer hier nicht dargestellten Gewindemutter erfolgen, die gegen die dem Raum "e" zugewandte Seite der Montagewand 5 geschraubt wird.The wire entry 1 of the FIG. 1 and 2 has an with respect to an axis 2 annular mounting sleeve 3, which is preferably made of an electrically insulating plastic material, and has on the outer circumference a uniform material integrally formed collar 4. The mounting sleeve 3 can be mounted on a mounting wall 5 and enforce this, the collar. 4 expediently bears against the side of the mounting wall 5 facing the space "d". The Fixing the mounting sleeve 3 can be done by means of a threaded nut, not shown here, which is screwed against the space "e" facing side of the mounting wall 5.

Etwa in der Längsmitte der Montagehülse 3 ist eine quer zur Achse 2 ausgerichtete Querwand 6 ausgebildet, an der beim vorliegenden Ausführungsbeispiel insgesamt neun auf Abstand zueinander angeordnete Führungsbuchsen 7 ausgebildet sind, die sich von der Querwand 6 in der Zeichnung nach oben in Richtung zum Raum "d" hin erstrecken. An der den Führungsbuchsen 7 gegenüberliegenden Seite der Querwand 6 sind insgesamt neun Führungshülsen 8 ausgebildet, die koaxial zu den Führungsbuchsen 7 angeordnet sind und sich in entgegengesetzter Richtung in der Zeichnung nach unten zum Raum "e" hin erstrecken.Approximately in the longitudinal center of the mounting sleeve 3 is a transverse to the axis 2 aligned transverse wall 6 is formed at the present embodiment, a total of nine spaced apart guide bushes 7 are formed by the transverse wall 6 in the drawing upwards towards the room " d "extend. At the guide bushes 7 opposite side of the transverse wall 6 a total of nine guide sleeves 8 are formed, which are arranged coaxially with the guide bushes 7 and extend in the opposite direction in the drawing down to the space "e" out.

In der Querwand 6 befinden sich zwischen den Führungsbuchsen 7 und den gegenüberliegenden Führungshülsen 8 jeweils ein Durchbruch 9, die koaxial zu den Führungsbuchsen 7 und Führungshülsen 8 angeordnet sind. Die Durchbrüche 9 sind umfänglich jeweils von einem Anschlagbund 10 begrenzt, und zwar so, dass der Durchmesser des jeweiligen Durchbruchs 9 kleiner ist als der Durchmesser der Führungsbuchse 7 bzw. der Führungshülse 8. An der Innenseite der Montagehülse 3 sind zudem nach innen vorspringende Widerlager 11 vorgesehen, die an der der Querwand 6 zugewandten Seite eine zu letzterer etwa parallel ausgerichtete Anschlagfläche und an der der Querwand 6 abgewandten Seite eine Einführschräge aufweisen.In the transverse wall 6 are located between the guide bushes 7 and the opposite guide sleeves 8 each have an opening 9, which are arranged coaxially to the guide bushes 7 and guide sleeves 8. The openings 9 are circumferentially bounded in each case by a stop collar 10, in such a way that the diameter of the respective aperture 9 is smaller than the diameter of the guide bushing 7 and the guide sleeve 8. On the inside of the mounting sleeve 3 are also inwardly projecting abutment eleventh provided, on the side facing the transverse wall 6 have a stop face approximately parallel to the latter and an insertion bevel on the side facing away from the transverse wall 6.

In der Montagehülse 3 befinden sich zwei bezüglich der Achse 2 etwa kreiszylindrische Gehäuseeinsätze 14, 15, die aus einem elektrisch isolierenden Kunststoffmaterial bestehen und im Wesentlichen gleich gestaltet sind. Der eine Gehäuseeinsatz 14 ist in der Zeichnung von oben und der andere Gehäuseeinsatz 15 von unten in die Montagehülse 3 eingesetzt worden. Die Gehäuseeinsätze 14, 15 sind somit zu einer Ebene der Querwand 6 spiegelsymmetrisch angeordnet, wobei die einander zugewandten Stirnseiten an der Querwand 6 anliegen können und die einander abgewandten Stirnseiten der Gehäuseeinsätze 14, 15 mit den einander gegenüberliegenden Stirnflächen der Montagehülse 3 bündig abschließen können.In the mounting sleeve 3 are two with respect to the axis 2 approximately circular cylindrical housing inserts 14, 15, which consist of an electrically insulating plastic material and substantially the same are designed. The one housing insert 14 has been used in the drawing from above and the other housing insert 15 from below into the mounting sleeve 3. The housing inserts 14, 15 are thus arranged mirror-symmetrically to a plane of the transverse wall 6, wherein the mutually facing end faces can rest against the transverse wall 6 and the opposite end faces of the housing inserts 14, 15 can be flush with the opposite end faces of the mounting sleeve 3.

Am Außenumfang der Gehäuseeinsätze 14, 15 sind nach außen vorstehende Rastteile 16 materialeinheitlich angeformt, die einander diametral gegenüberliegen können. Die Rastteile 16 besitzen an der der Querwand 6 zugewandten Seite eine Einführschräge und an der der Querwand 6 abgewandten Seite eine zu letzterer etwa parallel ausgerichtete Anschlagfläche. Beim axialen Einschieben der Gehäuseeinsätze 14, 15 in die Montagehülse 3 korrespondieren die Einführschrägen der Rastteile 16 mit den Einführschrägen der Widerlager 11, wobei die Rastteile 16 etwas nach innen in Richtung zur Achse 2 hin gedrückt werden. Nach dem vollständigen Einschieben der Gehäuseeinsätze 14, 15 federn die Rastteile 16 in ihre Ausgangsstellung zurück und untergreifen die Widerlager 11 der Montagehülse 3, so dass die Anschlagfläche der Rastteile 16 an der Anschlagfläche der Widerlager 11 anliegt. Ein axiales Herausziehen der Gehäuseeinsätze 14, 15 aus der Montagehülse 3 ist nunmehr nicht mehr möglich.On the outer circumference of the housing inserts 14, 15 outwardly projecting locking parts 16 are integrally formed of the same material, which can be diametrically opposed to each other. The locking parts 16 have on the side facing the transverse wall 6 an insertion bevel and on the side facing away from the transverse wall 6 a to the latter approximately parallel aligned abutment surface. During axial insertion of the housing inserts 14, 15 in the mounting sleeve 3 correspond to the insertion bevels of the locking parts 16 with the insertion bevels of the abutment 11, wherein the locking members 16 are pressed slightly inward in the direction of the axis 2 out. After complete insertion of the housing inserts 14, 15, the latching parts 16 spring back into their starting position and engage under the abutments 11 of the mounting sleeve 3, so that the stop surface of the latching parts 16 rests against the abutment surface of the abutment 11. An axial withdrawal of the housing inserts 14, 15 from the mounting sleeve 3 is now no longer possible.

Eine zusätzliche Sicherung für einen dauerhaft zuverlässigen Halt der Gehäuseeinsätze 14, 15 in der Montagehülse 3 wird durch die Einbringung von Arretierteilen 19 in die Gehäuseeinsätze 14, 15 erzielt. Jeder Gehäuseeinsatz 14, 15 besitzt dafür zwei diametral gegenüberliegende Aussparungen 20, in welche je ein vorzugsweise aus einem elektrisch nicht leitenden Kunststoffmaterial hergestellter Arretierteil 19 hineingeschoben wird. Dadurch können die Rastteile 16 nicht mehr nach innen in Richtung zur Achse 2 hin verlagert werden, wodurch ein absolut fester Halt der Gehäuseeinsätze 14, 15 in der Montagehülse 3 gewährleistet ist. Die Arretierteile 19 können einen etwa L-förmigen Querschnitt aufweisen, wobei der kurze Schenkel des L in einer Erweiterung der Aussparung 20 gelagert ist. Weiterhin kann es zweckmäßig sein, die Arretierteile 19 in den Aussparungen 20 der Gehäuseteile 14, 15 unlösbar festzulegen, indem beispielsweise ein Presssitz oder eine Rastverzahnung an den Seitenflächen der Arretierteile 19 und Aussparungen 20 vorgesehen ist.An additional assurance for a permanently reliable hold of the housing inserts 14, 15 in the mounting sleeve 3 is achieved by the introduction of locking parts 19 in the housing inserts 14, 15. Each housing insert 14, 15 has for this purpose two diametrically opposite recesses 20, in each of which one preferably consists of one electrically non-conductive plastic material produced locking member 19 is pushed. As a result, the locking parts 16 are no longer displaced inwardly in the direction of the axis 2, whereby an absolutely firm grip of the housing inserts 14, 15 is ensured in the mounting sleeve 3. The locking members 19 may have an approximately L-shaped cross-section, wherein the short leg of the L is mounted in an extension of the recess 20.
