Dementsprechend vielfältig ist der Einsatzbereich für diese Steckverbinder. Sie werden insb. zum Anschluß von Meßgeräten, z.B. Druck-, Füllstands- oder Durchflußmeßgeräten, die einen entsprechenden Stecker aufweisen, eingesetzt.The area of application for these is correspondingly diverse Connectors. They will be used to connect Measuring devices, e.g. Pressure, level or Flow meters that have a corresponding connector have used.

In der DE-C 44 12 000 ist ein Stecker, insb. für den elektrischen Anschluß von Kraftfahrzeug-Anhängern, beschrieben, welcher umfaßt:

  • einen Bajonettring zur lösbaren Verbindung des Steckers mit einer Steckdose,
  • einen im Bajonettring drehbar angeordneten Kontakteinsatz mit Kontaktstiften,
  • einen an den Kontakteinsatz angeformten, sich radial nach außen in eine Nut im Bajonettring erstreckenden Absatzring,
  • eine auf der steckdosen-zugewandten Seite an den Kontakteinsatz angeformte, koxial zu dem Bajonettring verlaufende Innenhülse,
  • einen auf der steckdosen-abgewandten Seite an den Kontakteinsatz angeformten, koxial zu dem Bajonettring verlaufenden, ein Außengewinde aufweisenden Hohlzylinder,
  • ein auf den Hohlzylinder geschraubte Mutter,
  • eine die Mutter und einen steckdosen-abgewandten Abschnitt des Hohlzylinders ausfüllendes Dichtelement, und
  • ein die Mutter und den Dichtring in axialer Richtung durchdringendes Kabel.
DE-C 44 12 000 describes a plug, in particular for the electrical connection of motor vehicle trailers, which comprises:
  • a bayonet ring for detachable connection of the plug to a socket,
  • a contact insert rotatably arranged in the bayonet ring with contact pins,
  • a heel ring molded onto the contact insert and extending radially outward into a groove in the bayonet ring,
  • an inner sleeve molded onto the contact insert on the side facing the socket and running coaxially to the bayonet ring,

  • a nut screwed onto the hollow cylinder,
  • a sealing element filling the nut and a section of the hollow cylinder facing away from the socket, and
  • a cable penetrating the nut and the sealing ring in the axial direction.

Ein Nachteil eines solchen Steckers ist, daß Stecker und Steckdose durch einen Bajonettverschluß miteinander verbunden sind. Ein solcher Verschluß bietet keinen besonderen Schutz gegen das Eindringen von Staub oder Feuchtigkeit. Da der Kontakteinsatz drehbar in dem Bajonettring angeordnet ist, bestehen zusätzliche Spalte, durch die z.B. eindringende Feuchtigkeit in den gesamten Innenraum des Steckers gelangen kann.A disadvantage of such a connector is that the connector and Socket through a bayonet joint are connected. Such a closure offers none special protection against the ingress of dust or Humidity. Because the contact insert rotates in the Bayonet ring is arranged, there are additional gaps, through e.g. penetrating moisture throughout Can reach the interior of the plug.

In der deutschen Norm DIN 43 650: 'Steckverbinder, viereckige Bauform' ist ein Steckverbinder beschrieben, der mit einem Stecker mit drei flachlänglichen Kontaktstiften, einem flachlänglichen Schutzkontaktstift und einer in dessen Zentrum angeordneten Gewindebohrung zu verbinden ist, welcher Steckverbinder umfaßt:

  • ein Gehäuse,
    • mit einem koaxial zur Längsachse des Steckers verlaufenden ersten Gehäuseabschnitt, der eine durchgehende zentrale axiale Bohrung aufweist, in der eine Schraube zur Befestigung des Steckverbinders am Stecker angeordnet ist, und
    • mit einem rechtwinklig zu dem ersten Gehäuseabschnitt verlaufenden zweiten Gehäuseabschnitt,
  • ein den ersten und den zweiten Gehäuseabschnitt durchdringendes vieradriges Kabel,
  • eine auf der stecker-zugewandten Seite des ersten Gehäuseabschnittes angeordnete Dichtung und
  • einen im ersten Gehäuseabschnitt angeordneten Kontakteinsatz,
    • in dem vier Flachkontaktklemmen, mit denen die Adern des Kabels verbunden sind, versenkt angeordnet sind,
    • der eine durchgehende zentrale, axiale, von der Schraube durchdrungene Bohrung aufweist und
    • der durch die Schraube im ersten Gehäuseabschnitt fixiert ist.

    • which is fixed by the screw in the first housing section.

Bei diesem Steckverbinder ist es wegen der Befestigung des Steckverbinders am Stecker mittels einer durch den ersten Gehäuseabschnitt hindurchgeführten Schraube erforderlich, daß der zweite Gehäuseabschnitt, durch den das Kabel hindurchgeführt ist, rechtwinklig zu dem ersten Gehäuseabschnitt verläuft. Meßgeräte werden jedoch häufig an Meßorten eingesetzt, an denen nur ein begrenzter Raum für den Steckverbinder zur Verfügung steht. Eine durch den zweiten Gehäuseabschnitt vergrößerte Querschnittsfläche des Steckverbinders wirkt sich hier nachteilig aus.This connector is because of the attachment of the Connector on the connector by means of one through the first Screw through the housing section required, that the second housing section through which the cable passed through, perpendicular to the first Housing section runs. However, gauges are common used in measuring locations where only a limited space is available for the connector. One by the second housing section enlarged cross-sectional area of the The connector has a disadvantageous effect here.

Üblicherweise ist bei solchen Steckverbindern vorgesehen, an dem Kontakteinsatz auf dessen stecker-zugewandten Seite ein Dichtelement anzuordnen. Es verbleiben jedoch sowohl zwischen dem Kontakteinsatz und dem ersten Gehäuseabschnitt als auch zwischen der Schraube und dem ersten Gehäuseabschnitt Spalte, durch die z.B. Staub und Feuchtigkeit in den Steckverbinder eindringen können.In such connectors, it is usually provided that on the contact insert on the side facing the plug to arrange a sealing element.

Located in Hohlylinder 12 a cylindrical sealing element 4, which from the Hollow cylinder 12 protrudes somewhat. Via the sealing element 4 is to put a nut 5 on the external thread 121 of the hollow cylinder 12 is to be screwed.

Die Mutter 5 und das Dichtelement 4 sind in axialer Richtung von einem vieradrigen Kabel 3 durchdrungen. Der in diesem Gehäuseabschnitt bestehende Hohlraum ist somit vollständig vom Dichtelement 4 ausgefüllt. Beim Aufschrauben der Mutter 5 wird der Endbereich des Hohlzylinder 12 radial nach innen gedrückt und somit abdichtend gegen das Kabel 3 gepreßt.The nut 5 and the sealing element 4 are in axial Direction penetrated by a four-core cable 3. The in this housing section is thus cavity completely filled by the sealing element 4. At the Screwing the nut 5 is the end of the Hollow cylinder 12 pressed radially inwards and thus sealingly pressed against the cable 3.

Auf einer stecker-zugewandten Ringfläche des Konus 11 ist eine Nut 14 zur Aufnahme einer Dichtung 6 angeordnet. Diese ist beispielsweise eine Formdichtung oder ein O-Ring aus einem Elastomer.On a plug-facing ring surface of the cone 11 a groove 14 for receiving a seal 6 is arranged. This is, for example, a molded seal or an O-ring an elastomer.

Auf der stecker-zugewandten Seite schließt der Konus 11 mit einem an dessen äußerer Ringfläche angeformten, sich in axialer Richtung erstreckenden Ring 15 ab. Dieser umfaßt den in Fig. 1 nicht dargestellten Stecker endseitig koaxial. Dadurch wird erreicht, daß Spritzwasser außen an dem Gehäuse 1 abfließt und gar nicht erst bis zu der Dichtung 6 gelangen kann. The cone 11 also closes on the side facing the plug one molded on its outer ring surface, in from the axial direction extending ring 15. This includes the plug, not shown in Fig. 1 at the end coaxial. This ensures that water splashes on the outside drains the housing 1 and not at all up to the Seal 6 can get.

Der Ring 15 weist eine in dessen Innerem umlaufende Kante 8 auf, durch die die Dichtung 6 in der Nut 14 fixiert ist. Dies bewirkt eine Erleicherung bei der Montage des Steckverbinders.The ring 15 has an edge 8 running around the inside thereof through which the seal 6 is fixed in the groove 14. This causes a relief when assembling the Connector.

Das Gehäuse 1 besteht aus einem transparenten, chemisch hochbeständigen Kunststoff, insb. aus Polyacrylsulfon.The housing 1 consists of a transparent, chemical highly resistant plastic, esp. from polyacrylic sulfone.

In dem Gehäuse 1 ist ein Kontakteinsatz 2 angeordnet. Dies ist beispielsweise ein spritztechnisch hergestelltes Kunststoffelement, z.B. aus Polyacrylsulfon.A contact insert 2 is arranged in the housing 1. This is for example an injection molded one Plastic element, e.g. made of polyacrylic sulfone.

Im dargestellten Ausführungsbeispiel weist das Gehäuse 1 einen runden Querschnitt auf. Alle genannten Merkmale und Eigenschaften gelten jedoch gleichermaßen für ein Gehäuse, das auf der stecker-zugewandten Seite einen rechteckigen oder quadratischen Querschnitt aufweist. Bei einem solchen Gehäuse sind lediglich die Nut 14, der Ring 15 und die Dichtung 6 entsprechend rechteckig zu ersetzen.In the exemplary embodiment shown, the housing 1 a round cross-section. All mentioned features and However, properties apply equally to a housing, the one on the side facing the plug is a rectangular one or has a square cross section. With such a Housing are only the groove 14, the ring 15 and the Seal 6 to be replaced accordingly rectangular.

In Fig. 2 ist eine Seitenansicht des Kontakteinsatzes 2 dargestellt. Dieser umfaßt einen Zylinder 21 und einen Bajonettring 23.2 is a side view of the contact insert 2 shown. This comprises a cylinder 21 and one Bayonet ring 23.

In Fig. 3 ist eine Draufsicht auf den Kontakteinsatz 2 von dessen stecker-abgewandten Seite dargestellt, die den Bajonettring 23 zeigt. Dieser weist vier Verschlußelemente auf, die jeweils aus einem an den Bajonettring 23 angeformten, senkrecht zur Symmetrieachse Y des Kontakteinsatzes 2 verlaufenden, spitzwinkligen Ringsegment 24 und einem daran anschließenden, sich parallel zur Symmetrieachse Y erstreckenden Anschlag 25 bestehen. Jedes Ringsegment 24 weist außen eine parallel zur Symmetrieachse Y verlaufende Nut 26 auf.In Fig. 3 is a plan view of the contact insert 2 of its side facing away from the connector is shown, the Bayonet ring 23 shows. This has four closure elements on, each of which is attached to the bayonet ring 23 molded, perpendicular to the axis of symmetry Y des Contact insert 2 running, acute-angled ring segment 24 and a subsequent, parallel to Axis of symmetry Y extending stop 25 exist. Each Ring segment 24 has an outside parallel to the axis of symmetry Y extending groove 26.

An einem der Anschläge 25 ist auf dessen ringsegment-abgewandten Seite endseitig eine sich radial nach außen erstreckende Schulter 22 angeformt. Das Gehäuse 1 weist auf der stecker-zugewandten Seite eine entsprechende Ausnehmung 16 zur Aufnahme der Schulter 22 auf, vgl. Fig. 1. Dadurch liegt bei jedem Einbau die gleiche Orientierung des Kontakteinsatzes 2 im Gehäuse 1 vor.At one of the stops 25 is on its ring segment facing away One end radially outwards extending shoulder 22 integrally formed. The housing 1 has a corresponding recess on the side facing the plug 16 for receiving the shoulder 22, cf. Fig. 1. This the same orientation of the Contact insert 2 in the housing 1 before.

Das Gegenstück des Bajonettrings 23 im Gehäuse 1 ist in Fig. 4 dargestellt und besteht aus vier spitzwinkligen, in einer Ebene an der Gehäuse-Innenwand angeformten Ringsegmenten 19. Benachbart zu zwei einander gegenüberliegenden Ringsegmenten 19 der vier Ringsegmente 19 ist auf deren stecker-abgewandten Seite jeweils eine in axialer Richtung im Gehäuse 1 verlaufende Rastnase 17 angeformt, wie in Fig. 5 gezeigt ist.The counterpart of the bayonet ring 23 in the housing 1 is in Fig. 4 shown and consists of four acute-angled, in molded on one level on the inner wall of the housing Ring segments 19. Adjacent to two each other opposite ring segments 19 of the four ring segments 19 is in each case on the side facing away from the connector Latch 17 extending in the axial direction in the housing 1 molded, as shown in Fig. 5.

Der Kontakteinsatz 2 ist in das Gehäuse 1 einzuführen und anschließend zu drehen, so daß der Bajonettring 23 mit den Ringsegmenten 24 auf den Ringsegmenten 19 des Gehäuses 1 aufliegt und die Anschläge 25 an den Ringsegmenten 19 anliegen. Dabei rasten die beiden Rastnasen 17 in die beiden entsprechenden, einander gegenüberliegenden Nuten 26 ein. Der Kontakteinsatz 2 ist somit fixiert und nicht mehr drehbar. Er ist nur noch mittels eines Werkzeugs wieder lösbar.The contact insert 2 is inserted into the housing 1 and then to rotate so that the bayonet ring 23 with the Ring segments 24 on the ring segments 19 of the housing 1 rests and the stops 25 on the ring segments 19th issue. The two latches 17 snap into place two corresponding, opposite grooves 26 on. The contact insert 2 is thus fixed and no longer rotatable. He is only again using a tool solvable.

Der Kontakteinsatz 2 weist weiterhin vier durchgehende, in Fig. 3 dargestellte, Bohrungen 29 auf. In diese kann ein entsprechendes Werkzeug, z.B. eine vierzinkige Gabel, angesetzt werden, mit dem der Kontakteinsatz 2 im Gehäuse 1 gedreht und aus dem Gehäuse 1 herausgenommen werden kann. Dies bietet Schutz vor einer unsachgemäßen oder unbefugten Behandlung, insb. einem Vertauschen der Anschlüsse.The contact insert 2 also has four continuous, in 3, bores 29. In this one can appropriate tool, e.g. a four-pronged fork, with which the contact insert 2 in the housing 1 rotated and can be removed from the housing 1. This offers protection from improper or unauthorized Treatment, especially swapping the connections.

Fig. 6 zeigt einen Längsschnitt durch den Kontakteinsatz 2. Er weist eine zentrale, axiale, durchgehende Bohrung 27 zur Aufnahme einer Schraube 7 auf. Dies Bohrung 27 weist einen mittleren Bereich mit geringerem Durchmesser auf. Beim ersten Einschrauben der Schraube 7 schneidet diese ein Gewinde in diesen Bereich und nach dem Einschrauben befindet sich das Gewinde der Schraube 7 auf der stecker-zugewandten Seite dieses mittleren Bereichs. Dadurch ist die Schraube 7 unverlierbar im Kontakteinsatz 2 gehalten.6 shows a longitudinal section through the contact insert 2. It has a central, axial, continuous bore 27 Pick up a screw 7. This bore 27 has one middle area with a smaller diameter. At the first screw in the screw 7 cuts it Thread in this area and after screwing in is the thread of screw 7 on the connector-facing Side of this middle area. This is the screw 7 captively held in the contact insert 2.

Um die Bohrung 27 herum sind vier axiale Bohrungen 28 mit rechteckigen Querschnitten auf einem Kreis angeordnet. In diesen Bohrungen 28 sind Flachkontaktklemmen versenkt. Die Adern des Kabels 3 sind mit entsprechenden Flachsteckern versehen und auf der stecker-abgewandten Seite in die Flachkontaktklemmen eingesteckt.Around the bore 27 are four axial bores 28 with rectangular cross sections arranged on a circle. In these bores 28 are sunk flat contact terminals. The wires of the cable 3 are with corresponding Provide tabs and on the connector-facing Inserted into the flat contact terminals.

Montiert wird der Steckverbinder, indem zunächst die Adern des Kabels 3 am Kontakeinsatz 2 angeschlossen werden. Anschließend ist das Gehäuse 1 über den Kontakteinsatz 2 und das Kabel 3 zu führen und der Bajonettverschluß zu schließen. Dann ist der Steckverbinder mittels der Schraube 7 auf dem in den Figuren nicht dargestellten Stecker zu befestigen. Die Verschraubung erfolgt durch die stecker-abgewandte Öffnung des Gehäuses 1 hindurch. Durch das Einstecken der Kontaktstifte des Steckers in die Flachkontaktklemmen im Kontakteinsatz 2 ist ein Verdrehen des Steckverbinders um dessen Längsachse gegenüber dem Stecker unterbunden. Die Dichtung 6 wird daher bei der Montage nicht verdreht oder aufgeworfen sondern nur gepreßt. Abschließend ist das Dichtelement 4 auf das Kabel 3 zu schieben und die Mutter 5 zu montieren.The connector is assembled by first pulling the wires of cable 3 can be connected to contact insert 2. The housing 1 is then over the contact insert 2 and to lead the cable 3 and the bayonet lock conclude. Then the connector is by means of the screw 7 on the plug, not shown in the figures fasten. The screw connection is done by the connector-facing Opening the housing 1 through. By the Insert the contact pins of the plug into the Flat contact terminals in contact insert 2 are twisted of the connector about its longitudinal axis relative to the Plug prevented. The seal 6 is therefore in the Assembly not twisted or posed, just pressed. Finally, the sealing element 4 is on the cable 3 and to mount the nut 5.

Das Gehäuse 1 weist in diesem Ausführungsbeispiel drei endseitig auf der stecker-zugewandten Seite angeformte, in Fig. 1 und in Fig. 4 dargestellte Zapfen 18 auf. Diese rasten in entsprechende im Stecker anzuordnende Öffnungen ein. Die Zapfen 18 bewirken einen zusätzlichen Schutz gegen ein Verdrehen des Steckverbinders um dessen Längsachse gegenüber dem Stecker. Eine solche Verdrehung kann bei Gehäusen mit rundem Querschnitt z.B. dann auftreten, wenn die Kontaktstifte in den Flachkontaktklemmen nicht fest eingeklemmt sind.The housing 1 has three in this embodiment molded on the end on the side facing the plug, in Fig. 1 and pin 18 shown in Fig. 4. This snap into corresponding openings in the connector on. The pins 18 provide additional protection against rotating the connector about its longitudinal axis opposite the connector. Such a twist can Housings with a round cross-section e.g. then occur when the contact pins in the flat contact terminals are not tight are trapped.

In der Innenwand des Konus 11 können zwei Lichtleiter 9 angeformt sein. Ein erstes Ende der Lichtleiter 9 grenzt an den Stecker an. Ein zweites Ende der Lichtleiter 9 grenzt an einen Abschnitt 91 des Gehäuses 1 an, der dünnwandig ausgebildet ist. Genau wie das Gehäuse 1 bestehen die Lichtleiter aus Polyacrylsulfon. Die Lichtleiter 9 dienen dazu, Licht, z.B. von einer an dem Stecker angeordneten Leuchtdiode zu leiten, so daß durch den Steckverbinder hindurch erkennbar ist, ob die Leuchtdiode eingeschaltet ist oder nicht. Eine solche Leuchtdiode wird bei Meßgeräten z.B. dazu verwendet, den Betriebszustand des Meßgeräts, z.B. An/Aus, oder einen Alarm anzuzeigen.In the inner wall of the cone 11, two light guides 9 be molded on. A first end of the light guide 9 is adjacent the plug. A second end of the light guide 9 borders to a section 91 of the housing 1, which is thin-walled is trained. Just like the housing 1, there are Light guide made of polyacrylic sulfone. The light guides 9 serve to light, e.g. from one arranged on the plug Conduct light-emitting diode so that through the connector through it can be seen whether the LED is switched on is or not. Such a light emitting diode is used in measuring devices e.g. used to determine the operating state of the measuring device, e.g. On / Off, or to display an alarm.
