Abstract
Description
Die Erfindung betrifft eine Schaltvorrichtung für eine Vorrichtung zum Überwachen eines Behälterfüllstandes, insbesondere eines Ausgleichsbehälters einer hydraulischen Kraftfahrzeugbremsanlage, mit einer an einem Kontaktträger befestigbaren Platine zur Festlegung eines Schaltpunktes in Relation zu dem Kontaktträger, wobei die Platine mindestens einen Reedkontakt trägt, der mittels eines magnetischen Gebers schaltbar ist, sobald der magnetische Geber durch Absinken des Behälterfüllstandes den Schaltpunkt passiert.The The invention relates to a switching device for a device for monitoring a container fill level, in particular an expansion tank a hydraulic motor vehicle brake system, with one on one contact support attachable circuit board to determine a switching point in relation to the contact carrier, wherein the board carries at least one reed contact that can be switched by means of a magnetic encoder as soon as the magnetic encoder by lowering the tank level passed the switching point.
In einer hydraulischen Kraftfahrzeugbremsanlage befindet sich die benötigte Bremsflüssigkeit in dem Ausgleichsbehälter, wobei der Behälterfüllstand durch den magnetischen Geber mit Schaltkontakten überwacht wird. Senkt sich der Bremsflüssigkeitsstand, so schließen sich die Schaltkontakte. Dieses Signal wird in einem Steuergerät ausgewertet und der Fahrer des Kraftfahrzeuges kann durch eine Leuchte gewarnt werden. Dabei muss sichergestellt sein, dass der Ausgleichsbehälter immer mit einem Minimum an Bremsflüssigkeit gefüllt ist, um die Funktion der Bremsanlage nicht in Frage zu stellen. In der Regel werden Vorrichtungen zum Überwachen eines Behälterfüllstandes verwendet, bei denen ein mit einem Magneten versehener Schwimmer einen Reedkontakt schaltet, sobald der Schwimmer eine Lage (Schaltpunkt) einnimmt, in der der Behälterfüllstand ein definiertes Minimum unterschreitet. Durch den Reedkontakt wird dann ein für den Fahrer erkennbares Warnsignal ausgelöst, wobei dann von diesem geeignete Gegenmaßnahmen einzuleiten sind.In The required brake fluid is located in a hydraulic motor vehicle brake system in the expansion tank, whereby the tank fill level through the magnetic encoder is monitored with switch contacts. It sinks Brake fluid level, so close the switch contacts. This signal is evaluated in a control unit and the driver of the motor vehicle can be warned by a light become. It must be ensured that the expansion tank is always with a minimum of brake fluid filled is in order not to question the function of the brake system. Usually devices are used to monitor a tank level used in which a float provided with a magnet switches a reed contact as soon as the float reaches a position (switching point) occupies at which the container fill level falls below the defined minimum. Then through the reed contact one for triggerable warning signal triggered by the driver, with the driver then issuing a suitable warning signal countermeasures are to be initiated.
Eine derartige Schaltvorrichtung ist beispielsweise aus der WO 98/11583 A1 bekannt. Die hierin beschriebene Schaltvorrichtung ist in einer Kammer angeordnet, welche sich unterhalb eines magnetischen Schwimmers befindet. Sinkt der Behälterfüllstand, nähert sich der Schwimmer der Schaltvorrichtung, welche dem Fahrer des Kraftfahrzeuges den Druckmittelverlust mittels eines Warnsignals anzeigt.A such a switching device is for example from WO 98/11583 A1 known. The switching device described herein is in a chamber arranged, which is below a magnetic float located. If the tank level drops, approaches the float of the switching device, which the driver of the Motor vehicle the loss of pressure medium by means of a warning signal displays.

Des weiteren sind Schaltvorrichtungen bekannt, wobei ein Kontaktträger mit Kunststoff umspritzte Kontaktfahnen aufweist. An einem ersten Ende der Kontaktfahnen ist ein Steckverbindergehäuse angeformt. An einem zweiten, aus dem Kunststoff herausragenden Ende ist mindestens ein Reedkontakt angelötet.Of further switching devices are known, with a contact carrier with Has plastic molded contact tabs. At a first end A connector housing is molded onto the contact lugs. On a second, the end protruding from the plastic is at least one reed contact soldered.
Nachteilig bei den bekannten Schaltvorrichtungen ist, dass der Schaltpunkt durch die Befestigung der Reedkontakte festgelegt ist. Wird der Schaltpunkt beispielsweise durch eine konstruktive Änderung des Ausgleichsbehälters verschoben, ist somit auch eine konstruktive Änderung der Schaltvorrichtung notwendig.adversely in the known switching devices is that the switching point is fixed by the fastening of the reed contacts. Will the switching point shifted, for example, by a design change to the expansion tank, is therefore also a design change of the switching device necessary.
Es ist daher Aufgabe der Erfindung, eine in dieser Hinsicht verbesserte, kostengünstige Schaltvorrichtung bereitzustellen.It is therefore the object of the invention, an improved in this regard, inexpensive To provide switching device.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Platine Mittel zur Änderung des Schaltpunktes aufweist. Dadurch ist eine Änderung der Schaltvorrichtung nicht notwendig, wenn sich der Schaltpunkt durch eine Änderung des Ausgleichsbehälters ändert. Es können somit die Einzelteile unverändert verwendet werden, ohne das ein zusätzlicher Herstellungsaufwand entsteht.According to the Task solved by that the board means of change of the switching point. This is a change in the switching device not necessary if the switching point changes of the expansion tank changes. It can thus the individual parts unchanged can be used without the additional manufacturing effort arises.
Vorzugsweise weist die Platine mindestens eine Sollbruchstelle auf. Diese Sollbruchstelle ermöglicht eine Längenänderung der Platine. Dies bedeutet, dass die Platine mit geringem Aufwand an eine vorgegebene Anforderung bezüglich des Schaltpunktes angepasst werden kann. Um eine möglichst große Bandbreite abzudecken ist es möglich, mehrere Sollbruchstellen an der Platine vorzusehen.Preferably the board has at least one predetermined breaking point. This predetermined breaking point allows a change in length the circuit board. This means that the board with little effort adapted to a specified requirement regarding the switching point can be. To have the widest possible range to cover it is possible to provide several predetermined breaking points on the board.
In vorteilhafter Weiterbildung der Erfindung weist die Platine eine Stanznut als Sollbruchstelle auf, welche bei der Herstellung in die Platine eingebracht werden kann.In In an advantageous development of the invention, the board has a Punching groove as a predetermined breaking point, which during manufacture in the board can be inserted.
In dem Kontaktträger sind Kontaktstifte vorgesehen, welche eine Kontaktübertragung sowie eine Befestigung der Platine an einem Ende der Kontaktstifte ermöglichen, wobei die Platine vorzugsweise durch Löten an den Kontaktstiften befestigt ist. Es werden somit keine weiteren Mittel zur Befestigung der Platine benötigt, da die Platine mit Lötstreifen versehen ist. Gleichzeitig dient diese Lötverbindung auch der Kontaktübertragung.In the contact carrier contact pins are provided, which transmit a contact and an attachment of the board to one end of the contact pins enable, wherein the board is preferably attached to the contact pins by soldering is. So there are no other means to attach the board needed because the board with solder strips is provided. At the same time, this solder connection also serves for contact transmission.
Um eine lagerichtige Fixierung der Platine in einer Lötvorrichtung zu ermöglichen, sind gemäß einer vorteilhaften Ausführungsform der Erfindung an der Platine Fixierelemente zur Aufnahme der Platine in der Lötvorrichtung vorgesehen. Dadurch wird gewährleistet, dass die Platine bei der Herstellung der Schaltvorrichtung in der richtigen Lage an den Kontaktträger angelötet wird. Die Fixerelemente können beispielsweise als Bohrungen oder Ausnehmungen in der Platine ausgestaltet sein.In order to enable the board to be fixed in the correct position in a soldering device, according to an advantageous embodiment of the invention fixing elements are provided on the board for receiving the board in the soldering device. This ensures that the board is in the correct position on the con during the manufacture of the switching device clock carrier is soldered. The fixer elements can be configured, for example, as bores or recesses in the board.
