Description

Die Erfindung bezieht sich auf einen Diagnosestecker für eine Diagnoseeinrichtung zum Überprüfen der Stromaufnahme eines in einem Stromkreis liegenden Verbrauchers, wobei der Stromkreis eine zur Aufnahme einer Sicherung geeigneten Buchse aufweist und der Diagnosestecker zwei zur Buchse passenden Messkontakte hat. The invention relates to a diagnostic connector for a diagnostic device for checking the power consumption a consumer in a circuit, wherein the circuit one for receiving a fuse has suitable socket and the diagnostic connector two to Socket has matching measuring contacts.

Ein solcher Stecker ist in der DE 26 54 487 C2 beschrieben. Demnach ist ein elektrischer Sicherungskasten vorgesehen, der zugleich eine Steckdose für eine Diagnoseeinrichtung darstellt. Zur Überprüfung der an den Sicherungskasten angeschlossenen Stromkreise, werden die Sicherungen, im allgemeinen Schmelzsicherungen, entnommen und an deren Stelle der Stecker der Diagnoseeinrichtung eingesetzt. Dieser ist entweder Teil der Diagnoseeinrichtung selbst oder mit diesem über ein Kabel verbunden. Insbesondere zum Überprüfen von Stromkreisen in einem Personenkraftfahrzeug sind beide Varianten von Nachteil. Der Sicherungskasten befindet sich häufig an einer nicht leicht zugänglichen Stelle, so dass sich die Diagnoseeinrichtung ebenfalls an einer ungünstigen Stelle befindet, wenn der Stecker ein Teil von ihr ist. Wenn der Stecker mit der Diagnoseeinrichtung über ein Kabel verbunden ist, wird das Verbindungskabel Teil des Stromkreises, so dass keine unverfälschten Messungen mehr vorgenommen werden können. Such a plug is in DE 26 54 487 C2 described. Accordingly, an electrical fuse box provided that at the same time a socket for a Diagnostic device represents. To check on the Fuse box connected circuits, the Fuses, generally fuses taken and in its place the plug of the diagnostic device used. This is either part of Diagnostic device itself or connected to this via a cable. In particular for checking circuits in one Passenger vehicles are both variants of disadvantage. The fuse box is often not on one easily accessible place, so that the Diagnostic device is also located in an unfavorable position, if the plug is part of it. When the plug connected to the diagnostic device via a cable, the connection cable becomes part of the circuit so that no more unadulterated measurements are made can.

Die Erfindung beruht somit auf dem Problem, einen Diagnosestecker für eine Diagnoseeinrichtung zu schaffen, so dass diese bequem einsetzbar ist und möglichst exakte Aussagen über den Stromkreis bzw. die in dem Stromkreis liegenden Verbraucher liefert. The invention is thus based on the problem, a To provide diagnostic connector for a diagnostic device, so that this is convenient to use and as accurate as possible Statements about the circuit or in the circuit supplies consumers.

Zur Lösung des Problems sieht die Erfindung einen Diagnosestecker für eine Diagnoseeinrichtung zur Überprüfung der Stromaufnahme gemäß dem Oberbegriff des Anspruchs 1 vor, bei dem der Diagnosestecker einen Messwiderstand zwischen den Messkontakten und einen Vorverstärker zum Verstärken der an dem Messwiderstand anliegenden Spannung besitzt und über ein mehradriges Kabel mit der Diagnoseeinrichtung verbunden ist. To solve the problem, the invention provides a Diagnostic connector for a diagnostic device for verification the current consumption according to the preamble of claim 1 before, in which the diagnostic connector has a measuring resistor between the measuring contacts and a preamplifier for Reinforcing the voltage applied to the measuring resistor owns and has a multi-core cable with the Diagnostic device is connected.

Auch bei diesem Diagnosestecker wird der an sich schon bekannte Vorteil genutzt, dass der Sicherungskasten gleichzeitig als Steckdose dienen kann. Um Verfälschungen des Messsignals entgegenzutreten, ist der Diagnosestecker mit einem kleinen Messwiderstand versehen, dessen Wert kleiner ist als der eines üblichen Sicherungswiderstandes, wobei der dort auftretende Spannungsabfall durch den im Diagnosestecker integrierten Vorverstärker proportional verstärkt wird. Das Ausgangssignal des Diagnosesteckers ist somit eine dem Strom proportionale Spannung, die über das Kabel mit der eigentlichen Diagnoseeinrichtung verbunden wird. Da der Vorverstärker eine deutlich erhöhte Spannung liefert, sind Störungen - verursacht durch das Kabel - zu vernachlässigen. Außerdem können die Kabelquerschnitte klein gehalten werden, da im Allgemeinen die Spannungseingänge der Diagnoseeinrichtungen hochohmig sind. Obwohl also die Diagnoseeinrichtung wegen der Kabelverbindung entfernt vom Sicherungskasten an einer leicht zugänglichen Stelle aufgebaut ist, erhält sie ausreichend genaue Spannungssignale. Even with this diagnostic connector is already in itself known advantage that used the fuse box can also serve as a socket. To distortions to counter the measuring signal, is the diagnostic connector provided with a small measuring resistor whose value smaller than that of a usual one Fuse resistance, wherein the voltage drop occurring there by the integrated preamplifier in the diagnostic connector is amplified proportionally. The output signal of the Diagnostic connector is thus a voltage proportional to the current, the over the cable with the actual Diagnostic device is connected. Because the preamp one clearly increased voltage supplies are faults - caused through the cable - to neglect. In addition, you can the cable cross sections are kept small, as in In general, the voltage inputs of the diagnostic equipment are high impedance. So although the diagnostic device because the cable connection away from the fuse box an easily accessible location, it receives sufficiently accurate voltage signals.

Vorzugsweise ist das Kabel mittels einer Steckverbindung mit dem Diagnosestecker verbunden, was die Austauschbarkeit bei Defekten erleichtert. Preferably, the cable is by means of a plug connection connected to the diagnostic connector, what the Interchangeability of defects facilitated.

Die Messkontakte, der Messwiderstand und der Vorverstärker und ggf. die Steckverbindung sind auf einer Platine angeordnet, wobei diese Platine zwei Zungen in Form der Messkontakte aufweist, die zumindest einseitig mit einem elektrischen Leiter flächig belegt sind, der insbesondere bei hochstromigen Varianten ein Metall ist. The measuring contacts, the measuring resistor and the Preamplifier and possibly the connector are on a circuit board arranged, this board two tongues in the form of Measuring contacts, which at least one side with a electrical conductors are occupied areally, in particular in high current variants is a metal.

Der Erfindungsgedanke wird im Folgenden anhand eines Ausführungsbeispiels erläutert. The inventive concept will be described below with reference to a Embodiment explained.

Die einzige Figur zeigt einen Sicherungskasten 1 mit einer zweipoligen Buchse 2, in der eine übliche Schmelzsicherung 3 eingesteckt ist. Die Buchse 2 liegt in einem Gleichspannungsstromkreis, in dem mehrere Verbraucher 4, 5 parallel angeordnet sind. Jeder Verbraucher 4, 5 kann ggf. über einen gesonderten Schalter 6, 7 ein- bzw. ausgeschaltet werden. Zur Diagnose der Stromaufnahme eines eingeschalteten Verbrauchers 4, 5 wird die Schmelzsicherung 3 entfernt, was mit dem Pfeil 8 angedeutet sein soll. Anstelle der Schmelzsicherung 3 wird ein Diagnosestecker 9 eingeführt. Dieser ist über ein Kabel 10 mit einer Diagnoseeinrichtung 11 verbunden. Hierbei kann es sich um ein handelsübliches Spannungsmessgerät bzw. um einen Datenlogger mit einem Spannungseingang handeln. The single FIGURE shows a fuse box 1 with a two-pin socket 2 , in which a conventional fuse 3 is inserted. The socket 2 is located in a DC voltage circuit in which a plurality of consumers 4 , 5 are arranged in parallel. Each consumer 4 , 5 can optionally via a separate switch 6 , 7 switched on or off. To diagnose the current consumption of a switched-consumer 4 , 5 , the fuse 3 is removed, which should be indicated by the arrow 8 . Instead of the fuse 3 , a diagnostic connector 9 is introduced. This is connected via a cable 10 to a diagnostic device 11 . This may be a commercially available voltmeter or a datalogger with a voltage input.

Der Diagnosestecker 9 besteht aus einer Platine 12 mit zwei Zungen 13, 14, die ein- oder beidseitig mit flachen Leiterbahnen 15, 16 versehen sind. Die Kontur der Zungen 13, 14 entspricht der Kontur der Messkontakte der Schmelzsicherung 3, so dass, wie dies durch den Pfeil 17 angedeutet sein soll, der Diagnosestecker 9 ohne weiteres an Stelle der Schmelzsicherung 3 in die Buchse 2 eingesteckt werden kann. The diagnostic connector 9 consists of a circuit board 12 with two tongues 13 , 14 , which are provided on one or both sides with flat conductor tracks 15 , 16 . The contour of the tongues 13 , 14 corresponds to the contour of the measuring contacts of the fuse 3 , so that, as indicated by the arrow 17 , the diagnostic connector 9 can be plugged into the socket 2 readily instead of the fuse 3 .

Die beiden Leiterbahnen 15, 16 sind über einen Messwiderstand 18 verbunden. Bei einem Stromfluss im Stromkreis fällt dort eine Spannung ab, die mittels eines Vorverstärkers 19, der ebenfalls auf der Platine 12 angeordnet ist, in etwa um den Faktor 100 verstärkt wird. Zur Stromversorgung des Vorverstärkers 19 und zur Weiterleitung des verstärkten Spannungssignals ist das vieladrige Kabel 10 vorgesehen, das über eine Steckverbindung 20 mit dem Diagnosestecker 9 verbunden ist. The two interconnects 15 , 16 are connected via a measuring resistor 18 . During a current flow in the circuit, a voltage drops there, which is amplified by a factor of approximately 100 by means of a preamplifier 19 , which is also arranged on the circuit board 12 . To power the preamplifier 19 and for forwarding the amplified voltage signal, the multi-core cable 10 is provided, which is connected via a plug connection 20 with the diagnostic connector 9 .

In der Regel ist der Vorverstärker 19 somit an das Bordnetz z. B. eines Personenkraftwagens angeschlossen. Damit der Vorverstärker 19 aber unabhängig von dort auftretenden Spannungsschwankungen (Startvorgang) ist, die den Messvorgang negativ beeinflussen würden, kann er auch an eine externe Spannungsquelle angeschlossen werden, die zusätzlich im Diagnosestecker 9 stabilisiert wird. Die hierfür benötigten elektrischen Bauelemente sind ebenfalls auf der Platine 12 angeordnet In general, the preamplifier 19 is thus connected to the electrical system z. B. a passenger car connected. However, in order for the preamplifier 19 to be independent of any voltage fluctuations (starting process) which would adversely affect the measurement process, it can also be connected to an external voltage source, which is additionally stabilized in the diagnostic connector 9 . The electrical components required for this purpose are likewise arranged on the circuit board 12

In dieser Ausführung ist der Diagnosestecker 9 mit einem Paar Messkontakte 18 zur Überprüfung eines Stromkreises ausgeführt. Er wird somit anstelle einer Schmelzsicherung 3 zur Diagnose des angeschlossenen Stromkreises eingesetzt. Prinzipiell können auch mehrere Diagnosestecker zusammengefasst werden. So lange aber die Sicherungskästen verschiedener Fahrzeughersteller durchaus unterschiedlich aufgebaut sind, empfiehlt sich dies nicht unbedingt, um die Flexibilität des Systems zu erhalten. In this embodiment, the diagnostic connector 9 is designed with a pair of measuring contacts 18 for checking a circuit. It is thus used instead of a fuse 3 for diagnosis of the connected circuit. In principle, several diagnostic connectors can be combined. However, as long as the fuse boxes of different vehicle manufacturers are built quite differently, this is not necessarily recommended to maintain the flexibility of the system.

Die verwendeten Messwiderstände sind in Stufen jeweils an einen bestimmten Nennstrombereich des zu prüfenden Stromkreises angepasst, wobei der Messwiderstand umso größer je kleiner der Nennstrom ist, so dass die Ausgangsspannungen des Diagnosesteckers 9 nach der Vorverstärkung im Bereich zwischen 0,6 und 3,8 Volt liegt. Wenn der Diagnosestecker 9 mit einem relativ großen Messwiderstand versehen ist, kann er auch eingesetzt werden, um die Ruheströme von permanent im Stromkreis liegenden Verbrauchern zu bestimmen. In diesem Fall ist aber eine Schutzschaltung notwendig, die ebenfalls auf der Platine untergebracht werden kann. Bezugszeichenliste 1 Sicherungskasten

The measuring resistors used are adapted in stages in each case to a specific rated current range of the circuit to be tested, wherein the measuring resistor is greater, the smaller the rated current, so that the output voltages of the diagnostic connector 9 after preamplification in the range between 0.6 and 3.8 volts , If the diagnostic connector 9 is provided with a relatively large measuring resistor, it can also be used to determine the quiescent currents of consumers permanently in the circuit. In this case, however, a protective circuit is necessary, which can also be accommodated on the board. List of Reference Numerals 1 fuse box
