Abstract

1. A plug connector for detachably connecting cable lines, consisting of a plug socket (2) and of a plug which can be coupled thereto, with a hollow-cylindrical plug housing (7) and with a contact insert (10) which accommodates exchangeable bush contacts (12) and which consists of insulating material, where sealing elements (11, 14) are inserted, in elastically deformed fashion, between the bush contacts (12) and the contact insert (10) and between the contact insert (10) and the plug housing (7), characterised in that the contact insert (10) consists of several parts and one part (10c) of the contact insert (10) contains conical bores into which are inserted, in shape-locking fashion, sealing elements (11) which surround the bush contacts (12) and which rest in the axial direction against another part (10b) of the contact insert (10), where the plug housing (7) is divided and one part (7a) can be screwed into the other part (7b) thus compressing the contact insert components (10b, 10c) and the sealing elements (11) arranged between them.

Description

Die vorliegende Erfindung betrifft einen Steckverbinder zum lösbaren Anschluß von Kabelleitungen entsprechend dem gattungsbildenden Teil des Patentanspruchs 1.The present invention relates to a connector for the detachable connection of cable lines according to the generic part of claim 1.

Derartige Steckverbinder sind gemäß der US-PS-4 355 855 bekannt. Die Dichtelemente zwischen den Kontakten und den sie aufnehmenden Bohrungen des Kontakteinsatzes bestehen dort aus O-Ringen, weshalb es zur Montage bzw. zum Auswechseln der Kontakte schon einer nennenswerten Kraftanwendung bedarf.Such connectors are known according to US Pat. No. 4,355,855. The sealing elements between the contacts and the bores of the contact insert which receive them there consist of O-rings, which is why an appreciable application of force is required to mount or to replace the contacts.

Die Erfindung stellt sich die Aufgabe, die Kontakte bei einem Steckverbinder der eingangs genannten Art .leichter montierbar zu gestalten und trotzdem auch bei extremen Umgebungsbedingungen, z. B. bei im Störfall in kerntechnischen Anlagen unter 6,5 bar austretendem Heißdampf, mit einer zuverlässigen Feuchtigkeits- bzw. Dampfsperre zu versehen.The invention has for its object to make the contacts in a connector of the type mentioned easier to assemble and still in extreme environmental conditions, eg. B. in the event of a malfunction in nuclear plants under 6.5 bar escaping superheated steam, with a reliable moisture or vapor barrier.

Gelöst wird diese Aufgabe erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen.This object is achieved according to the invention with the features specified in the characterizing part of patent claim 1.

Die Erfindung samt ihrer weiteren, im Anspruch 2 wiedergegebenen Ausgestaltung soll nachstehend anhand der Zeichnung näher erläutert werden.The invention and its further embodiment, as set out in claim 2, will be explained in more detail below with reference to the drawing.

Diese zeigt einen Längsschnitt durch einen erfindungsgemäßen Steckverbinder.This shows a longitudinal section through a connector according to the invention.

In die Wandung eines nicht näher dargestellten Gehäuses 1 ist die Steckdose 2 der Steckverbindung eingelassen und mittels eines Gewinderinges 3 befestigt. Zwischen Steckdose 2 und der Wandung des Gehäuses 1 ist eine O-Ringdichtung 4 vorgesehen. Die Steckdose 2 weist in einen Isolierkörper 5 eingelassene Steckerkontakte 6 auf, von denen drei in der Zeichnung dargestellt sind. In die Steckdose 2 ist ein im wesentlichen hohlzylinderförmiges zweiteiliges Steckergehäuse 7a, 7b eingeschoben und mittels einer Überwurfmutter 8 fest mit ihr gekuppelt. Ein 0-Ring 9 ist zur Abdichtung zwischen Steckergehäuse 7a und Steckdose 2 vorgesehen. Das Innere des Steckergehäuses 7 nimmt einen aus Isolierstoff bestehenden Kontakteinsatz auf, der aus mehreren Teilen 10a. 10b und 10c besteht, wovon der Einsatzteil 10c kegelige Bohrungen aufweist, in welche formschlüssig entsprechend geformte kegelstumpfförmige Aufsätze einer gummielastischen Dichtscheibe 11 eingebracht sind, welche eine zylindrische Bohrung zur Aufnahme der Kontaktbuchsen 12 aufweisen. Die abisolierten Enden der Adern 13 eines nicht in der Zeichnung dargestellten kabels werden mittels einer Quetschverbindung jeweils mit einem der Buchsenkontakte 12 kontaktiert. Das Kabelende befindet sich in einer Dichtverschraubung, welche mittels eines Innengewindes am Steckergehäuse 7b befestigt ist. Die beiden Teile 7a und 7b des Steckergehäuses können mittels eines Gewindes soweit zusammengeschraubt werden, daß flüssigkeits- bzw. dampfdichte Berührungsflächen zwischen den kegeligen Ansätzen der Dichtscheibe 11 und dem Kontakteinsatzteil 10c sowie den zylindrischen Bohrungswandungen der Dichtscheibe 11 und den diesen zugeordneten Umfangsbereichen der Buchsenkontakte 12 entstehen. Anstelle einer Dichtscheibe 11 können auch einzelne, nicht miteinander verbundene, kegelstumpfförmig ausgebildete Dichtelemente verwendet werden, welche jeweils eine zylindrische Bohrung zur Aufnahme der der Kabeleinführung zugeordneten Enden der Kontaktbuchsen 12 aufweisen.In the wall of a housing 1, not shown, the socket 2 of the connector is embedded and fastened by means of a threaded ring 3. An O-ring seal 4 is provided between the socket 2 and the wall of the housing 1. The socket 2 has plug contacts 6 embedded in an insulating body 5, three of which are shown in the drawing. An essentially hollow cylindrical two-part connector housing 7a, 7b is inserted into the socket 2 and firmly coupled to it by means of a union nut 8. A 0-ring 9 is provided for sealing between the connector housing 7a and the socket 2. The inside of the connector housing 7 receives a contact insert made of insulating material, which consists of several parts 10a. 10b and 10c, of which the insert part 10c has tapered bores, into which form-fitting, correspondingly shaped, frustoconical attachments of a rubber-elastic sealing washer 11 are introduced, which have a cylindrical bore for receiving the contact sockets 12. The stripped ends of the wires 13 of a cable, not shown in the drawing, are each contacted with one of the socket contacts 12 by means of a crimp connection. The cable end is located in a sealing screw connection, which is fastened to the connector housing 7b by means of an internal thread. The two parts 7a and 7b of the connector housing can be screwed together by means of a thread to such an extent that liquid- or vapor-tight contact surfaces arise between the conical approaches of the sealing washer 11 and the contact insert part 10c and the cylindrical bore walls of the sealing washer 11 and the peripheral regions of the socket contacts 12 assigned to them . Instead of a sealing washer 11, it is also possible to use individual, non-interconnected, frustoconical sealing elements, each of which has a cylindrical bore for receiving the ends of the contact bushings 12 assigned to the cable entry.

Insgesamt wird durch die Erfindung eine hochwirksame Abdichtung geschaffen, welche sehr montagefreundlich ist und ohne weiters auch bel nur teilbestückten Steckern verwendbar ist, wenn eine entsprechende Anzahl von Blindkontaktbuchsen, d. h. nicht mit Kabeladern verbundene Kontaktbuchsen in den Kontakteinsatz eingebracht werden.Overall, a highly effective seal is created by the invention, which is very easy to assemble and can also be used only partially populated plugs if a corresponding number of blind contact sockets, ie. H. Contact sockets that are not connected to cable cores are inserted in the contact insert.
