Abstract
Description
Die Erfindung betrifft ein Steuergerät mit einer Leiterplatte und einem darin eingesetzten Shunt zur Strommessung. Unter Steuergerät wird hierbei insbesondere ein Türsteuergerät für ein Kraftfahrzeug verstanden. Sie betrifft weiter einen auf eine derartige Leiterplatte montierbaren Shunt zur Strommessung.The The invention relates to a control device with a printed circuit board and a shunt used for current measurement. Under control unit is in particular a door control device for a motor vehicle Roger that. It further relates to such a circuit board mountable shunt for current measurement.
Ein Steuergerät eines Kraftfahrzeugs umfasst üblicherweise mindestens eine ein- oder mehrlagige Leiterplatte, die mit einer Anzahl von elektronischen Bauteilen bestückt ist. Die Bauteile übernehmen innerhalb einer entsprechenden Baugruppe die jeweils anwendungsspezifischen Steuerfunktionen innerhalb des Steuergerätes. Zu einer solchen Baugruppe gehört auch ein Shunt – üblicherweise in Form eines Kontaktblechs – zur Strommessung.On control unit of a motor vehicle usually includes at least one single or multi-layer printed circuit board, which with a Number of electronic components is populated. Take over the components the respective application-specific within a corresponding module Control functions within the control unit. To such an assembly heard also a shunt - usually in the form of a contact plate - for Current measurement.
Der Shunt ist dabei in entsprechende Leiterplattenöffnungen, die auch als Langlöcher ausgeführt sein können, eingesetzt und mit zugeordneten Kontaktbahnen auf der Leiterplatte verlötet. Die Lötverbindung kann sich jedoch beim Betrieb der entsprechenden Baugruppe aufgrund der betriebsbedingt starken Erwärmung infolge der über den Shunt geführten hohen Blockströme lösen, so dass die erforderliche elektrische Kontaktierung des Shunts auf der Leiterplatte äußerst problematisch ist. Zudem erfordert das Einsetzen des Shunts sowie dessen sichere Kontaktierung eine kostenintensiver Handbestückung der Leiterplatte sowie einen zusätzlichen Lötprozess.The The shunt is in corresponding circuit board openings, which are also designed as elongated holes can, used and with assigned contact tracks on the circuit board soldered. The solder joint may, however, result from the operation of the corresponding module the strong warming caused by operation as a result of over led the shunt high block currents to solve, so that the required electrical contacting of the shunt on the PCB extremely problematic is. It also requires the insertion of the shunt and its safe Contacting an expensive manual assembly of the circuit board as well an additional soldering process.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Steuergerät, insbesondere für ein Kraftfahrzeug, mit einem in einer Leiterplatte zuverlässig kontaktierten Shunt anzugeben. Insbesondere soll eine einfache Handhabbarkeit des Shunts bei dessen Verbindung und Kontaktierung mit der Leiterplatte des Steuergerätes bei gleichzeitig zuverlässiger Kontaktierung in allen Betriebszuständen des Steuergerätes sichergestellt sein.The The invention is therefore based on the object of a control device, in particular for a Motor vehicle, with a reliably contacted in a circuit board Specify shunt. In particular, ease of handling should of the shunt when it is connected and contacted with the circuit board of the control unit with reliable contacting at the same time in all operating states of the control unit be assured.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Dazu weist der Shunt mindestens zwei über einen Kontaktschenkel miteinander verbundene Fixierschenkel auf, die jeweils freiendseitig mindestens einen massiven Einpresspin oder Einpressstift aufweisen, der in der Verbindung mit einem Leiterplattenloch eine (massive) Einpresszone bildet. Unter massiv wird hierbei ein Einpresspin verstanden, der sich im Gegensatz zu einem flexiblen Einpresspin beim Einpressen nicht verformt.This The object is achieved by the features of claim 1. For this purpose, the shunt has at least two over one Contact legs connected to each other fixing legs, each at least one solid press-in pin or press-in pin on the free end have the one in connection with a circuit board hole (massive) press-in zone. Here, a press-in pin becomes solid understood, which is in contrast to a flexible press-in pin not deformed when pressed in.
Zweckmäßigerweise weist jeder Fixierschenkel zwei derartige Einpresspins auf, um in Verbindung mit den entsprechend ausgebildeten massiven Einpresszonen eine möglichst große Stromtragfähigkeit in der Leiterplatte zu erreichen.Conveniently, each fixation leg has two such push-in pins in order to Connection with the correspondingly designed press-fit zones one if possible size ampacity in the circuit board.
Die Einpresspins sind durch an die Fixierschenkel angeformte Stiftschäfte gebildet, an deren Übergangsbereich zum diese tragenden Fixierschenkel eine Einpresshilfe vorgesehen ist. Diese ist zweckmäßigerweise durch eine Einpress- und/oder Anlageschulter gebildet, mit der der Shunt im Montageendzustand zusätzlich auch auf der Leiterplatte aufliegen kann. Alternativ kann die Einpresshilfe auch in Form einer in den Fixierschenkel eingebrachten Bohrung oder Sicke ausgeführt sein, in die oder an die beim Einpressvorgang ein entsprechendes Einpresswerkzeug ein- angreift.The Press-in pins are formed by pin shafts molded onto the fixing legs, at their transition area a press-in aid is provided for these fixing legs is. This is convenient formed by a press-in and / or contact shoulder with which the Shunt additionally in the final assembly state can also rest on the circuit board. Alternatively, the press-in aid can also be used in the form of a hole or bead made in the fixing leg accomplished be into or to which a corresponding press-in tool during the press-in process attacks.
An den im Querschnitt zweckmäßigerweise rechteckförmigen Stiftschaft schließt sich eine Stiftspitze am Schaftende an. Diese Stiftspitze bildet quasi eine Einlaufschräge beim Einsetzen des Shunts in die den jeweiligen Einpresspins zugeordneten, zweckmäßigerweise durchkontaktierten Leiterplattenlöcher. Dies ermöglicht, insbesondere bei einer automatisierten Leiterplattenbestückung, eine zuverlässige Montage des Shunts, der hierzu mittels dessen Einpresspins in die durchkontaktierten Leiterplattenlöcher eingepresst wird.On the pin shaft, which is expediently rectangular in cross section includes a pen tip at the end of the shaft. This pen tip forms quasi an inlet slope when inserting the shunt in the assigned to the respective press-in pins, expediently plated-through circuit board holes. This makes possible, especially with an automated PCB assembly, a reliable Assembly of the shunt, which is done by pressing it into the plated-through circuit board holes is pressed.
Dabei wird ein besonders günstiges Einpressverhalten einerseits und eine besonders zuverlässige elektrische Kontaktierung sowie mechanische Haltbarkeit andererseits dadurch erzielt, dass die Kanten des rechteckförmigen Stiftschaftes angefast sind. Der Shunt selbst besteht zweckmäßigerweise aus einem U-förmig gebogenen Kontaktblech mit zweckmäßigerweise rechteckförmigem Querschnitt.there will be a particularly affordable one Press-in behavior on the one hand and a particularly reliable electrical Contacting as well as mechanical durability on the other hand achieved that the edges of the rectangular pin shaft beveled are. The shunt itself expediently consists of a U-shaped curve Contact plate with expediently rectangular Cross-section.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch Einpressen des Shunts in die Leiterplatte eines Steuergerätes, insbesondere für ein Kraftfahrzeug, eine Montagevereinfachung bei gleichzeitig sicherer elektrischer Kontaktierung des Shunts auf der Leiterplatte erreicht ist. Der bei der Leiterplattenbestückung mittels einer Einpress-Station eingepresste Shunt kann ohne separates oder selektives Löten montiert werden.The Advantages achieved with the invention are in particular that by pressing the shunt into the circuit board of a control device, in particular for a Motor vehicle, an assembly simplification at the same time safer electrical contact of the shunt on the circuit board is achieved is. The one in the PCB assembly using a press-in station Pressed-in shunt can be assembled without separate or selective soldering become.
