Description

Die Erfindung betrifft eine elektrische Funktionsgruppe für ein Fahrzeug gemäß Oberbegriff von Anspruch 1.The invention relates to an electrical functional group for a vehicle according to the preamble of claim 1.

In Fahrzeugen befindet sich eine Vielzahl von elektrischen Baueinheiten, die über Steckverbindungen elektrisch miteinander verbunden sind. Dies kann z. B. eine Glühlampe sein, die über eine Steckverbindung mit einer Spannungsquelle verbunden ist, oder auch ein Steuergerät, an dem über Steckverbindungen diverse Sensoren und zu steuernde Aggregate angeschlossen sind.There are a large number of electrical units in vehicles which are electrically connected to one another via plug connections. This can e.g. B. be an incandescent lamp, which is connected via a plug connection to a voltage source, or also a control unit, to which various sensors and units to be controlled are connected via plug connections.

Löst sich eine solche Steckverbindung, so sind die darüber verbundenen elektrischen Baueinheiten nicht mehr funktionsfähig. Dies stellt bei sicherheitsrelevanten Systemen, wie z. B. einer Kfz-Airbagauslöseschaltung, eine Gefahr für die beförderten Personen dar. Bei anderen Systemen, wie Zündsteuergeräten für Verbrennungskraftmaschinen, kann es zu Motorschäden kommen, die teure Reparaturen nach sich ziehen.If such a plug connection becomes detached, the electrical units connected via it are no longer functional. This represents security-related systems such. B. a motor vehicle airbag release circuit, a hazard for the transported people. Other systems, such as ignition control devices for internal combustion engines, can lead to engine damage, which result in expensive repairs.

Um diesen Gefahren zu begegnen, ist eine laufende Betriebsüberwachung solcher Systeme nicht ausreichend, da damit eine einmal gelöste Steckverbindung zwar sofort erkannt wird, aber die nachteiligen Wirkungen bereits eingetreten sind.In order to counter these dangers, ongoing operational monitoring of such systems is not sufficient, since a plug connection that has been disconnected is recognized immediately, but the adverse effects have already occurred.

Die Aufgabe der Erfindung besteht deshalb darin, eine elektrische Steckverbindung so zu überwachen, daß ein Lösevorgang der Steckverbindung erkannt werden kann, bevor der eigentliche Nutzkreis, der die elektrischen Baueinheiten miteinander verbindet, aufgetrennt ist.The object of the invention is therefore to monitor an electrical plug connection so that a release process of the plug connection can be recognized before the actual useful circuit that connects the electrical components to one another is disconnected.

Die erfindungsgemäße Lösung ist in Anspruch 1 gekennzeichnet.The solution according to the invention is characterized in claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.

Bei der erfindungsgemäßen Lösung wird eine Steckverbindung verwendet, die aus einem Steckteil mit Kontaktstiften und einem Buchsenteil mit Kontakthülsen zur Aufnahme der Kontaktstifte besteht. Der Steckteil hat mindestens einen Nutzkontakt, der aus einem langen Kontaktstift besteht, über den die elektrischen Baueinheiten in einem Nutzkreis verbunden werden. Zusätzlich hat der Steckteil mindestens einen Meldekontakt, der aus einem kurzen Kontaktstift besteht. Beim Zusammenschieben der Steckverbindung kommen also die Nutzkontakte vor dem Meldekontakt in elektrische Verbindung mit den entsprechenden Kontakthülsen des Buchsenteils. Beim Lösen der Steckverbindung löst dagegen der Meldekontakt vor den Nutzkontakten.In the solution according to the invention, a plug connection is used which consists of a plug part with contact pins and a socket part with contact sleeves for receiving the contact pins. The plug-in part has at least one useful contact, which consists of a long contact pin, via which the electrical units are connected in a useful circuit. In addition, the plug-in part has at least one signaling contact, which consists of a short contact pin. When the plug connection is pushed together, the useful contacts come in electrical connection with the corresponding contact sleeves of the socket part before the signaling contact. On the other hand, when the plug connection is released, the signaling contact in front of the user contacts is released.

Eine solche Steckverbindung ist aus anderen technischen Gebieten bereits bekannt. In der deutschen Offenlegungsschrift 32 12 983 ist ein abziehbarer Stecker offenbart, der zwei lange Starkstromkontaktstifte und einen kurzen Schwachstromkontaktstift umfaßt. Über die beiden Starkstromkontaktstifte ist ein Starkstromkreis geführt, der über den Schwachstromkontaktstift mit Hilfe eines Halbleiterschalters ein- und ausgeschaltet wird. Dadurch wird eine Lichtbogenbildung beim Lösen des Steckers verhindert, da der Starkstromkreis bereits abgeschaltet ist, bevor die Starkstromkontaktstifte lösen.Such a connector is already known from other technical fields. In German Offenlegungsschrift 32 12 983 a removable plug is disclosed which comprises two long high-current contact pins and a short low-current contact pin. A high-voltage circuit is guided over the two high-voltage contact pins, which is switched on and off via the low-voltage contact pin with the aid of a semiconductor switch. This prevents arcing when the plug is removed, since the power circuit is already switched off before the power contact pins release.

Bei der erfindungsgemäßen Applikation einer solchen Steckverbindung besteht keine Wirkverbindung der über den kurzen Meldekontakt und den langen Nutzkontakt geführten Stromkreise. Der kurze Meldekontakt ist hier Teil eines Meldekreises, der eine Überwachungseinrichtung enthält, die prüft ob der Meldekreis über den Meldekontakt geschlossen ist. Ist dies nicht der Fall, so gibt die Überwachungseinrichtung eine Warnmeldung aus. Diese kann optisch oder akustisch zur Anzeige gebracht werden, so daß der Betreiber des Fahrzeuges auf die sich lösende Steckverbindung aufmerksam gemacht wird bevor der Nutzkreis unterbrochen ist.In the application of such a plug connection according to the invention, there is no operative connection between the circuits routed via the short signaling contact and the long useful contact. The short signaling contact is part of a signaling circuit that contains a monitoring device that checks whether the signaling circuit is closed via the signaling contact. If this is not the case, the monitoring device issues a warning message. This can be displayed optically or acoustically, so that the operator of the vehicle is made aware of the detachable plug connection before the useful circuit is interrupted.

Die Erfindung wird anhand der Figuren erläutert; es zeigen

FIG 1
eine elektrische Funktionsgruppe und
FIG 2
eine elektrische Baueinheit mit einem Steckteil.
The invention is explained with reference to the figures; show it
FIG. 1
an electrical functional group and
FIG 2
an electrical unit with a plug-in part.

In FIG 1 ist ein Nutzkreis mit zwei elektrischen Baueinheiten 31, 32 dargestellt, der über Leitungen und eine im aufgetrennten Zustand gezeichnete elektrische Steckverbindung aus einem Steckteil 1 und einem Buchsenteil 2 geschlossen wird.1 shows a useful circuit with two electrical units 31, 32, which is closed via lines and an electrical plug connection drawn in the disconnected state from a plug part 1 and a socket part 2.

Die elektrischen Baueinheiten 31, 32 stehen stellvertretend für beliebige in Fahrzeugen verwendete elektrische Teile oder Einheiten, die elektrisch über Steckverbindungen miteinander verbunden sind.The electrical units 31, 32 represent any electrical parts or units used in vehicles, which are electrically connected to one another via plug connections.

Der Steckteil 1 der Steckverbindung hat einen langen Nutzkontakt 11, der beim Zusammenschieben der Steckverbindung von einer entsprechend langen Kontakthülse 21 des Buchsenteils 2 aufgenommen wird. Beim Zusammenschieben übergreifen Haltenasen 23 des Buchsenteils 2 den Steckteil 1 und rasten in der geschlossenen Stellung in entsprechende Kerben 13 des Steckteils 1 ein.The plug part 1 of the plug connection has a long useful contact 11, which is received by a correspondingly long contact sleeve 21 of the socket part 2 when the plug connection is pushed together. When pushed together, retaining lugs 23 of the socket part 2 overlap the plug part 1 and engage in the closed position in corresponding notches 13 of the plug part 1.

Der Steckteil 1 hat außerdem einen Meldekontakt 12, der kürzer als der Nutzkontakt 11 ist, und der in der geschlossenen Stellung der Steckverbindung von einer Kontakthülse 22 des Buchsenteils 2 aufgenommen wird. Über diesen Meldekontakt 12 wird ein Meldekreis geschlossen, wobei der Meldekontakt 12 mit Masse verbunden ist und die Kontakthülse 22 mit einer Überwachungseinrichtung 4. Die Überwachungseinrichtung 4 ist ein Mikroprozessor, der laufend prüft, ob das Massepotential über die Steckverbindung anliegt.The plug-in part 1 also has a signaling contact 12, which is shorter than the useful contact 11, and which is received by a contact sleeve 22 of the socket part 2 in the closed position of the plug connection. A signaling circuit is closed via this signaling contact 12, the signaling contact 12 being connected to ground and the contact sleeve 22 to a monitoring device 4. The monitoring device 4 is a microprocessor which continuously checks whether the ground potential is present via the plug connection.

Beim Lösen der Steckverbindung löst sich zuerst der Meldekontakt 12 aus der Kontakthülse 22 des Buchsenteils 2. Dadurch liegt am Mikroprozessor das Massepotential nicht mehr an und dieser erzeugt eine Warnmeldung W. Diese Warnmeldung W bewirkt (in FIG 1 nicht dargestellt) das Aufleuchten einer Warnlampe, die den Betreiber des Fahrzeugs auf die sich lösende Steckverbindung aufmerksam macht. Dieser kann dann entsprechend eingreifen, noch bevor über den langen Nutzkontakt 11 der Nutzkreis aufgetrennt wird.When the plug connection is released, the signaling contact 12 first releases from the contact sleeve 22 of the socket part 2 the ground potential is no longer present at the microprocessor and this generates a warning message W. This warning message W (not shown in FIG. 1) causes a warning lamp to light up, which alerts the operator of the vehicle to the detachable plug connection. This can then intervene accordingly before the useful circuit is opened via the long useful contact 11.

Bei mehreren zu überwachenden Steckverbindungen können die einzelnen Meldekontakte 12 in Reihe in einem Meldekreis zusammengeschaltet werden. Dadurch wird nicht für jede Steckverbindung ein eigener Eingang am Mikroprozessor benötigt.If there are several plug connections to be monitored, the individual signaling contacts 12 can be connected in series in a signaling circuit. This means that a separate input on the microprocessor is not required for each plug connection.

FIG 2 zeigt als elektrische Baueinheit 33 ein Steuergerät mit einem am Gehäuse angebrachten Steckteil 1A. Die Nutzkontakte 11A sind hier als Messerkontakte in Form einer Messerleiste nebeneinander angeordnet. Rechts und links neben den Nutzkontakten 11A befindet sich je ein ebenfalls als Messerkontakt ausgebildeter Meldekontakt 12A. Die Meldekontakte 12A sind in Reihenschaltung am selben Meldekreis angeschlossen. Wäre z. B. nur der in FIG 2 linke Meldekontakt 12A vorhanden, so würde ein Lösen der Steckverbindung durch schräges Abziehen nicht rechtzeitig erkannt. Würde nämlich ein aufgesteckter Buchsenteil durch eine mechanische Einwirkung nach links abgeschert, so wäre insbesondere bei den rechts liegenden Nutzkontakten 11A die elektrische Verbindung bereits aufgetrennt, bevor der links liegende Meldekontakt 12A aufgetrennt wäre. Dies ist jedoch durch die Anordnung je eines Meldekontakts 12A an beiden Seiten des Steckteils 1A verhindert.2 shows as the electrical unit 33 a control device with a plug-in part 1A attached to the housing. The useful contacts 11A are arranged here next to one another as knife contacts in the form of a knife strip. To the right and left of the user contacts 11A there is a signaling contact 12A, which is also designed as a knife contact. The signaling contacts 12A are connected in series on the same signaling circuit. Would z. If, for example, only the signaling contact 12A on the left in FIG. 2 is present, loosening of the plug connection by pulling it off obliquely would not be recognized in good time. If an attached socket part were sheared off to the left by mechanical action, the electrical connection in particular would be disconnected in the case of the user contacts 11A on the right before the signaling contact 12A on the left would be disconnected. However, this is prevented by the arrangement of one signaling contact 12A on each side of the plug-in part 1A.

Die Verwendung von zwei oder mehreren Meldekontakten 12A ist nicht nur auf eine Ausführungsform gemäß FIG 2 beschränkt. Damit können ebenfalls vielpolige Rundsteckverbindungen oder asymmetrisch geformte Steckverbindungen überwacht werden. Die Anordnung der einzelnen Meldekontakte 12A hängt dabei von der Geometrie der Steckverbindung ab. Diese werden derart im Abstand voneinander angeordnet, daß beim Lösen der Steckverbindung durch ein verkantetes Abziehen in jedem Fall erst die elektrische Verbindung eines der Meldekontakte 12A unterbrochen wird.The use of two or more signaling contacts 12A is not only limited to an embodiment according to FIG. 2. It can also be used to monitor multipole circular connectors or asymmetrically shaped connectors. The arrangement of the individual signaling contacts 12A depends on the geometry of the plug connection. These are spaced like this arranged from each other so that when the plug connection is released by a jammed pull in any case the electrical connection of one of the signaling contacts 12A is interrupted.
