Description

Aus dem DE-G 89 02 403 U1 ist eine Kabeldurchführung mit einer elektrischen Steckverbindung bekannt, bei der in einer Öffnung einer Wand eine mit der Wand verbundene Hülse vorgesehen ist. Ein Stecker und eine Kupplung werden von außen in die Hülse eingeführt und, im gesteckten Zustand, durch Überwurfmuttern gesichert, die in ein Außengewinde der Hülse eingreifen. Dabei ist es allerdings nötig, zunächst die Hülse in der Wand zu befestigen, bevor Stecker und Kupplung in die Hülse eingeführt werden können.From DE-G 89 02 403 U1 a cable bushing with an electrical plug connection is known, in which a sleeve connected to the wall is provided in an opening in a wall. A plug and a coupling are inserted from the outside into the sleeve and, when plugged in, secured by union nuts which engage in an external thread of the sleeve. However, it is necessary to first fasten the sleeve in the wall before the plug and coupling can be inserted into the sleeve.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine fixierbare elektrische Steckverbindung zu schaffen, die mit einfachen Mitteln fixierbar ist.The invention specified in claim 1 is based on the problem of creating a fixable electrical connector that can be fixed with simple means.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die elektrische Steckverbindung ohne zusätzliche Montagemittel, sondern nur durch einfaches Einschieben in eine Öffnung eines langgestreckten Bauteiles und anschließendes Verrasten fixiert werden kann. Zur Verrastung notwendiger Vorsprünge in der Öffnung sind mit den zur Herstellung der Öffnung ohnehin notwendigen Bearbeitungswerkzeugen bei der Herstellung der Öffnung leicht zu erstellen. Die Vorsprünge können jede zur Verrastung dienliche Form haben. Darüber hinaus kommt die erfindungsgemäße Steckverbindung mit einer geringen Anzahl von Bauteilen aus.The advantages achieved by the invention consist in particular in that the electrical plug connection can be fixed without additional assembly means, but only by simply pushing it into an opening in an elongated component and then latching it. The projections necessary for latching in the opening can easily be created with the processing tools which are necessary anyway for producing the opening when producing the opening. The projections can have any shape that is useful for locking. In addition, the connector according to the invention manages with a small number of components.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawings and will be described in more detail below.

Es zeigen:

  • Fig. 1 eine Ansicht einer in einem Rastbolzen fixierten elektrischen Steckverbindung und
  • Fig. 2 einen Schnitt durch den Rastbolzen während eines Bearbeitungsvorganges.
Show it:
  • Fig. 1 is a view of an electrical connector fixed in a locking pin and
  • Fig. 2 shows a section through the locking bolt during a machining operation.

In Fig. 1 ist in einer Ansicht eine elektrische Steckverbindung 1 dargestellt, die aus einem als Stiftstecker ausgebildeten ersten Gehäuse 2 und einem als Buchsenstecker ausgebildeten zweiten Gehäuse 3 besteht. In den Gehäusen 2, 3 sind nicht dargestellte Buchsenkontakte bzw. Steckerkontakte gehalten, die mit elektrischen Leitdrähten 4 verbunden sind.In Fig. 1, an electrical plug connection 1 is shown in a view, which consists of a first housing 2 designed as a pin connector and a second housing 3 designed as a socket connector. Socket contacts or plug contacts, which are not shown, are held in the housings 2, 3 and are connected to electrical guide wires 4.

Die elektrische Steckverbindung 1 ist in einem langgestreckten Bauteil 5, hier einem als Befestigungselement für ein Kraftfahrzeug-Außenspiegel dienendem Rastbolzen, gelagert. Der Rastbolzen 5 weist eine durchgehende zylindrische Öffnung 6 auf, wobei der Innendurchmesser der Öffnung 6 etwas größer als der Außendurchmesser des ersten Gehäuses 2 gewählt ist. In einer Tiefe t bezogen auf die Kopffläche K des Rastbolzens 5 weist die Öffnung 6 einen umlaufenden Grat 7 auf, der mit einer am ersten Gehäuse 2 angeordneten Nut 8 in Eingriff steht.The electrical plug connection 1 is mounted in an elongate component 5, here a locking bolt serving as a fastening element for a motor vehicle exterior mirror. The locking pin 5 has a continuous cylindrical opening 6, the inside diameter of the opening 6 being chosen to be somewhat larger than the outside diameter of the first housing 2. At a depth t relative to the top surface K of the locking bolt 5, the opening 6 has a peripheral ridge 7 which engages with a groove 8 arranged on the first housing 2.

Zur Montage des ersten Gehäuses 2 werden die gegebenenfalls schon mit Buchsenkontakten oder Steckerkontakten versehenen elektrischen Leitdrähte 4 durch die Öffnung 6 des Rastbolzens 5 gezogen und in nicht dargestellten Halterungen im ersten Gehäuse 2 festgelegt. Sodann wird das erste Gehäuse 2 in die Öffnung 6 eingeschoben, bis die Nut 8 mit dem Grat 7 verrastet. Das erste Gehäuse 2 ist damit im Rastbolzen 5 fixiert.To assemble the first housing 2, the electrical guide wires 4, which are optionally already provided with socket contacts or plug contacts, are pulled through the opening 6 of the latching bolt 5 and fixed in holders (not shown) in the first housing 2. Then the first housing 2 is pushed into the opening 6 until the groove 8 engages with the ridge 7. The first housing 2 is thus fixed in the locking pin 5.

Der Rastbolzen 5 wird einschließlich der Öffnung 6 durch Fließpressen hergestellt. Hierzu werden u.a., wie in Fig. 2 dargestellt, zwei Bearbeitungswerkzeuge 9,10, hier ausgeführt als Stempel, benötigt. Die Stempel 9,10 werden von zwei Seiten in einen Rohling des Rastbolzens 5 eingepresst, bis ihre Kopfflächen 11,12 in einer Tiefe t zur Anlage kommen. Die Anlagefläche der Kopfflächen 11,12 ist als Werkzeugtrennebene W gekennzeichnet. Beide Kopfflächen 11,12 weisen umlaufende Fasen 13,14 auf, die bei der Bearbeitung den Grat 7 in der Tiefe t erzeugen.The locking pin 5 is made including the opening 6 by extrusion. For this purpose, as shown in FIG. 2, two processing tools 9, 10, here designed as stamps, are required. The punches 9, 10 are pressed into a blank of the locking bolt 5 from two sides until their head surfaces 11, 12 come to rest at a depth t. The contact surface of the head surfaces 11, 12 is identified as the tool parting plane W. Both head surfaces 11, 12 have circumferential bevels 13, 14, which produce the ridge 7 in depth t during processing.

Bei dem dargestellten Fertigungsverfahren ist es möglich, die Form des Grates 7 durch die Form der Fasen 13,14 zu bestimmen. Neben dem vorgeschlagenen umlaufenden Grat 7 sind ohne Beeinträchtigung der Funktion andere Formen denkbar. Die Tiefe t, in der der Grat, bezogen auf die Kopffläche K des Rastbolzens 5, zu liegen kommt, wird durch die Werkzeugtrennebene W bestimmt und ist einstellbar. Der Grat 7 kann durch alle Fertigungsverfahren erzeugt werden, die eine Bearbeitung oder Formung der Öffnung 6 von zwei Seiten erlauben.In the manufacturing process shown, it is possible to determine the shape of the burr 7 by the shape of the chamfers 13, 14. In addition to the proposed circumferential ridge 7, the function is not impaired other shapes possible. The depth t, in which the burr, based on the head surface K of the locking bolt 5, comes to lie, is determined by the tool parting plane W and is adjustable. The ridge 7 can be produced by all manufacturing processes that allow machining or shaping of the opening 6 from two sides.
