Description

Die Erfindung bezieht sich auf eine elektrische Kupplung, welche ein Stiftgehäuse und ein Buchsengehäuse aufweist, die mit ineinander steckbares, jeweils in einem Schutzköper aus Isoliermaterial angeordneten elektrischen Kontaktelementen ausgerüstet sind, an welche jeweils elektrische Leiter von elektrischen Leitungen angeschlossen sind, bei welcher die beiden Schutzkörper eine Steckseite und eine Anschlußseite für die jeweilige elektrische Leitung aufweisen.The invention relates to an electrical coupling, which has a pin housing and a female housing, which are equipped with plug-in, each arranged in a protective body of insulating electrical contact elements, to which each electrical conductor of electrical lines are connected, in which the two protective body have a plug side and a connection side for the respective electrical line.

Solche Kupplungen sind grundsätzlich bekannt und mit unterschiedlichen Anwendungen im Einsatz. Sie werden überall dort verwendet, wo zwei elektrische Leitungen zur Durchverbindung von elektrischen Übertragungswegen steckbar miteinander verbunden werden. Dabei kommt es in den meisten Anwendungsfälien nur darauf an, daß die zusammengesteckten Kontaktelemente ausreichend fest aneinander bzw. ineinander liegen. Das gilt auch für den Einsatz der Kupplungen für Leitungen, die in Kraftfahrzeugen verlegt sind. Hier kommt aber hinzu, daß die Leitungen und auch die Kupplungen allen Erschütterungen, insbesondere auch Vibrationen, ausgesetzt sind, die beim Getrieb eines Fahrzeuges auftreten. Durch solche Erschütterungen können Relativbewegungen zwischen den Kontaktelementen entstehen, durch welche der elektrische Kontakt zwischen denselben mit entsprechend erhöhten Übergangswiderständen verschlechtert wird.Such couplings are basically known and used with different applications. They are used everywhere where two electrical lines are plugged together to connect electrical transmission paths. It depends in most Anwendungsfälien only on the fact that the mated contact elements are sufficiently tight to each other or into each other. This also applies to the use of couplings for cables that are laid in motor vehicles. But here comes the fact that the lines and the couplings all shocks, especially vibrations are exposed, which occur in the transmission of a vehicle. By such vibrations relative movements between the contact elements can arise, through which the electrical contact between them is deteriorated with correspondingly increased contact resistance.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Kupplung so zu gestalten, daß der elektrische Kontakt zwischen den ineinander gesteckten Kontaktelementen mit hoher Qualität auf Dauer erhalten bleibt.The invention has for its object to make the above-described coupling so that the electrical contact between the nested contact elements with high quality is maintained over time.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß die Kontaktelemente des Buchsengehäuses mit ihren Außenflächen dicht am Material des Schutzkörpers desselben anliegen,
  • daß der Schutzkörper des Buchsengehäuses auf seiner Steckseite in radialer Richtung elastisch verformbar und mit sich zum Ende des Schutzkörpers verkleinernden äußerem Abmessungen konisch ausgeführt ist,
  • daß die zu den Kontaktelementen des Buchsengehäuses komplementären Kontaktelemente des Stiftgehäuses fest und unverrückbar im Schutzkörper des Stiftgehäuses angebracht sind,
  • daß der Schutzkörper des Stiftgehäuses einen Aufnahmeraum aufweist, der analog zum Schutzkörper des Buchsengehäuse zu dessen Aufnahme konisch ausgeführt ist, und
  • daß die lichten radialen Abmessungen des Aufnahmeraums des Stiftgehäuses geringfügig kleiner als die radialen Außenabmessungen des Buchsengehäuse sind.
This object is achieved according to the invention characterized
  • that the contact elements of the female housing with its outer surfaces tightly against the material of the protective body,
  • that the protective body of the female housing is designed to be elastically deformable on its plug-in side in the radial direction and to be conical with its outer dimensions decreasing towards the end of the protective body,
  • the complementary to the contact elements of the female housing contact elements of the pin housing are fixed and immovably mounted in the protective body of the pin housing,
  • that the protective body of the pin housing has a receiving space, which is designed to be analogous to the protective body of the female housing to its reception, and
  • that the clear radial dimensions of the receiving space of the pin housing are slightly smaller than the radial outer dimensions of the socket housing.

Bei dieser Kupplung ist das elastisch verformbare Buchsengehäuse im Montagezustand durch das Stiftgehäuse zusammengedrückt, weil dessen Aufnahmeraum gegenüber den Außenabmessungen des Buchsengehäuses kleinere leichte Abmessungen hat. Das Material des Schutzkörpers des Buchsengehäuses wird dadurch zusätzlich gegen die von demselben eng umgebenen, beispielsweise als Buchsenkontakte ausgeführten Kontaktelemente gedrückt. Diese Kontaktelemente sind damit auf Dauer unverrückbar im Buchsengehäuse festgelegt. Das gilt auch für die beispielsweise als Stifte ausgeführten Kontaktelemente des Stiftgehäuses, die fest und unverrückbar in dessen Schutzkörper angebracht sind. Buchsengehäuse und Stiftgehäuse sind in der fertiggestellten Kupplung wegen des geringen Untermaßes des Aufnahmeraums des Stiftgehäuses gegenüber dem Buchsengehäuse ebenfalls fest zusammengesteckt, so daß eine Relativbewegung zwischen den jeweiligen Kontaktelementen ausgeschlossen werden kann. Die Kontaktsicherheit der Kupplung ist damit auf Dauer in hoher Qualität gesichert, auch wenn dieselbe wiederholt und auch über einen längere Zeitraum Vibrationen ausgesetzt ist.In this coupling, the elastically deformable female housing is compressed in the assembled state by the pin housing, because its receiving space compared to the outer dimensions of the female housing has smaller, light dimensions. The material of the protective body of the female housing is thereby additionally pressed against the closely surrounded by the same, for example, designed as a socket contacts contact elements. These contact elements are thus permanently fixed immovably in the socket housing. This also applies to the example designed as pins contact elements of the pin housing, which are firmly and immovably mounted in the protective body. Socket housing and pin housing are also firmly mated in the finished coupling because of the small undersize of the receiving space of the pin housing relative to the socket housing, so that a relative movement between the respective contact elements can be excluded. The contact reliability of the clutch is thus secured in the long term in high quality, even if it is repeatedly and exposed to vibration over a longer period.

Der Schutzkörper des Buchsengehäuse hat in seinem die Kontaktelemente umgebenden konischen Bereich mit Vorteil mindestens einen in axialer Richtung verlaufenden Schlitz, durch welchen seine elastische Verformbarkeit bzw. das Andrücken seines Materials an die Kontaktelemente weiter verbessert ist.The protective body of the female housing advantageously has at least one in the axial direction in its conical region surrounding the contact elements extending slot through which its elastic deformability and the pressing of its material is further improved to the contact elements.

Die Kupplung nach der Erfindung wird im folgenden in einer Ausführungsform mit zwei Kontaktelementen zum Anschluß von zweiadrigen elektrischen Leitungen beschrieben. Sie kann aber für Leitungen mit mehr als zwei Adern auch mehr als zwei Kontaktelemente haben. Die geometrische Form der ineinander steckbaren Kontaktelemente ist beliebig, solange ein fester Sitz derselbe ineinander geweben ist. Sie sind in den Zeichnungen nur schematisch angedeutet. Stellvertretend für andere Ausführungsformen werden in der folgenden Beschreibung die Kontaktelemente des Buchsengehäuse als "Buchsenkontakte" und die des Stiftgehäuses als "Stifte" bezeichnet.The coupling according to the invention will be described below in an embodiment with two contact elements for connecting two-wire electrical lines. However, it can also have more than two contact elements for lines with more than two wires. The geometric shape of the plug-in contact elements is arbitrary, as long as a firm seat of the same is woven into each other. They are indicated only schematically in the drawings. Representative of other embodiments, the contact elements of the female housing as "female contacts" and the pin housing referred to as "pins" in the following description.

In Fig. 1 ist ein Stiftgehäuses S einer elektrischen Kupplung dargestellt, das einen Schutzkörper 1 aus Isoliermaterial mit einem an einer Stirnseite eine Öffnung aufweisenden Aufnahmeraum 2 zur Aufnahme eines Buchsengehäuses B (Fig. 2) der Kupplung hat. In dem Aufnahmeraum 2 sind zwei als Stifte 3 und 4 ausgebildete elektrische Kontaktelemente fest und unverrückbar angeordnet, an welche auf der der Öffnung gegenüberliegenden Seite des Schutzkörpers 1 die Leiter von zwei elektrischen Adern 5 und 6 einer nicht mit dargestellten elektrischen Leitung angeschlossen sind. Die elektrische Verbindung zwischen den Leitern und den Stiften 3 und 4 kann in übliche Technik erfolgten, beispielsweise durch Crimpen. Der Aufnahmeraum 2 ist zumindest in dem die Stifte 3 und 4 umgebenden Bereich konisch ausgeführt, mit in Richtung der Öffnung des Stiftgehäuses S zunehmenden Abmessungen.In Fig. 1 is a pin housing S an electrical coupling shown having a protective body 1 of insulating material with an opening at one end having a receiving space 2 for receiving a female housing B ( Fig. 2 ) of the coupling has. In the receiving space 2 as two pins 3 and 4 formed electrical contact elements are fixed and immovable, to which on the opposite side of the opening of the protective body 1, the conductors of two electrical wires 5 and 6 are connected to an electrical line not shown. The electrical connection between the conductors and the pins 3 and 4 can be done in conventional technology, for example by crimping. The receiving space 2 is at least in the area surrounding the pins 3 and 4 conical, with increasing in the direction of the opening of the pin housing S dimensions.

Fig. 2 zeigt ein Buchsengehäuse B einer elektrischen Kopplung, das in Montageposition in das Stiftgehäuses S eingesteckt ist (Fig. 3). Es hat einen Schutzkörper 7 aus Isoliermaterial, in dem zwei Buchsenkontakte 8 und 9 angeordnet sind, an welche die Leiter von zwei Adern 10 und 11 einer ebenfalls nicht mit dargestellten elektrischen Leitung in üblicher Technik angeschlossen sein können. Der den Adern 10 und 11 abgewandte Bereich des Schutzkörpers 7 ist konisch ausgeführt, mit sich zu seiner Steckseite hin verkleinernden radialen Abmessungen. An dieser Steckseite hat der Schutzkörper 7 Öffnungen, durch welche die Buchsenkontakte 8 und 9 zugänglich sind. Fig. 2 shows a female housing B of an electrical coupling which is inserted in the mounting position in the pin housing S ( Fig. 3 ). It has a protective body 7 made of insulating material, in which two socket contacts 8 and 9 are arranged, to which the conductors of two wires 10 and 11 may also be connected to an electrical line also not shown in the usual art. The the cores 10 and 11 facing away from the region of the protective body 7 is conical, with its plug-side towards downsizing radial dimensions. At this plug side of the protective body 7 has openings through which the socket contacts 8 and 9 are accessible.

Die Buchsenkontakte 8 und 9 werden von Material des Schutzkörpers 7 eng umschlossen, Dazu kann der Schutzkörper 7 in einem Spritzgießwerkzeug um die Buchsenkontakte 8 und 9 herumgespritzt sein. Der Schutzkörper 7 kann aber auch mit frei bleibenden Ausnehmungen für die Buchsenkontakte 8 und 9 sowie die Adern 10 und 11 maßgenau vorgefertigt sein. Die Buchsenkontakte 8 und 9 können dann nach dem Anschluß der Leiter der Adern 10 und 11 in derartige Ausnehmungen eingeschoben werden. Dabei legen sie sich dicht an die Wandungen der Ausnehmungen des Schutzkörper 7 an. Um die Adern 10 und 11 herum können innerhalb des Schutzkörpers 7 Dichtelemente 12 und 13 angebracht sein, welche die Buchsenkontakte 8 und 9 gegenüber Feuchtigkeit schützen, die gegebenenfalls über die Adern 10 und 11 eindringen könnte. Die Dichtelemente 12 und 13 verhindern auch die Übertragung von mechanischen Belastungen, insbesondere von Vibrationen, von der Adern 10 und 11 auf die Buchsenkontakte 8 und 9.The socket contacts 8 and 9 are closely enclosed by the material of the protective body 7, For this purpose, the protective body 7 may be injected around the socket contacts 8 and 9 in an injection mold. The protective body 7 can also be prefabricated with free remaining recesses for the socket contacts 8 and 9 and the wires 10 and 11 dimensionally accurate. The socket contacts 8 and 9 can then be inserted after the connection of the conductors of the wires 10 and 11 in such recesses. They put themselves close to the walls of the recesses of the protective body 7. Around the wires 10 and 11 around the protective body 7 sealing elements 12 and 13 may be attached, which protect the socket contacts 8 and 9 against moisture, which could possibly penetrate through the wires 10 and 11. The sealing elements 12 and 13 also prevent the transmission of mechanical loads, in particular vibrations, from the wires 10 and 11 to the socket contacts 8 and 9.

Die Stifte 3 und 4 des Stiftgehäuses S sind so bemessen, daß sie mit hoher Kontaktgabe in die Buchsenkontokte 8 und 9 des Buchsenteil B passen. Sie sind fest und unverrückbar im Schutzkörper 1 des Stiftgehäuses S angebracht. In der fertigen Kopplung greifen die Stifte 3 und 4 in die Buchsenkontakte 8 und 9 ein. Die lichte Weite des Aufnahmeraums 2 des Stiftgehäuses S ist in dessen radialer Richtung etwas kleiner als die radialen Außenabmessungen des Buchsengehäuses B. Der entsprechende Unterschied in den Abmessungen von Aufnahmeraum 2 des Stiftgehäuses S und Buchsengehäuses B muß so bemessen sein, daß das Buchsengehäuse B ohne allzu großen Kraftaufwand in das Stiftgehäuses S eingesteckt werden kann. Er soll aber ausreichend groß sein, um sicherzustellen, daß das Buchsengehäuse B zumindest in seinem die Buchsenkontakte 8 und 9 umgebenden Bereich elastisch zusammengedrückt wird. Das Material des Schutzkörpers 7 wird dann zusätzlich an die Buchsenkontakte 8 und 9 angedrückt.The pins 3 and 4 of the pin housing S are sized so that they fit with high contact in the socket Kontokte 8 and 9 of the female part B. They are firmly and immovably mounted in the protective body 1 of the pin housing S. In the finished coupling, the pins 3 and 4 engage in the socket contacts 8 and 9. The clear width of the receiving space 2 of the pin housing S is slightly smaller in the radial direction than the radial outer dimensions of the female housing B. The corresponding difference in the dimensions of receiving space 2 of the pin housing S and female housing B must be such that the female housing B without too much large force in the pin housing S can be inserted. But it should be sufficiently large to ensure that the socket housing B at least in its surrounding the socket contacts 8 and 9 Area is compressed elastically. The material of the protective body 7 is then additionally pressed against the socket contacts 8 and 9.

Um die elastische Verformbarkeit des Schutzkörpers 7 des Buchsengehäuses B zur verbessern, kann derselbe mit Vorteil im Bereich der Buchsenkontakte 8 und 9 mindestens einen in axialer Richtung verlaufenden Schlitz 14 aufweisen, dessen Länge vorzugsweise der Länge der Buchsenkontakte 8 und 9 entspricht. Die lichte Weite des Schlitzes 14 wird dann verringert, wenn der Schutzkörper 7 durch das Stiftgehäuse S zusammengedrückt wird. In bevorzugter Ausführungsform sind gemäß Fig. 4 vier in Umfangsrichtung gegeneinander versetzte, sich in axialer Richtung erstreckende Schlitze 15, 16, 17 und 18 im Schutzkörper 7 des Buchsengehäuses B vorhanden.In order to improve the elastic deformability of the protective body 7 of the female housing B, the same can advantageously have in the region of the female contacts 8 and 9 at least one slot 14 extending in the axial direction, the length of which preferably corresponds to the length of the female contacts 8 and 9. The inside width of the slot 14 is then reduced when the protective body 7 is compressed by the pin housing S. In a preferred embodiment are according to Fig. 4 four circumferentially offset from each other, extending in the axial direction slots 15, 16, 17 and 18 in the protective body 7 of the female housing B available.
