Offenlegungsschrift
Es besteht nun die Aufgabe, die vorstehend angeführte Herstellung von Sensoren mittels eines Spritzgussverfahrens zu verbessern.It is now the object to improve the above-mentioned production of sensors by means of an injection molding process.
Diese Aufgabe wird gelöst durch das Verfahren gemäß Anspruch 1.This object is achieved by the method according to
Nach der Erfindung wird die Klemmkraft von einem oder mehrere Halteelementen, zum Beispiel Klemmen, auf ein eingelegtes Bauelement, zum Beispiel auf die eingelegte Anschlußkabel eines Sensors, während des Umspritzvorgangs verändert bzw. variiert. Dies läßt sich beispielsweise durch eine sogenannte Übersetzung des im eingespritzten Material gemessenen Drucks in einen hydraulischen Druck erzielen, wobei durch den hydraulischen Druck ein Hydraulikzylinder betätigt wird, welcher mechanisch mit den Halteelementen verbunden ist.According to the invention, the clamping force of one or more holding elements, for example terminals, is changed or varied to an inserted component, for example to the inserted connecting cable of a sensor, during the extrusion coating process. This can be achieved for example by a so-called translation of the pressure measured in the injected material into a hydraulic pressure, wherein a hydraulic cylinder is actuated by the hydraulic pressure, which is mechanically connected to the holding elements.
Die elektronischen Kraftfahrzeugbauelemente sind bevorzugt elektronische Bauelemente eines Raddrehzahlsensors, welcher insbesondere nach einem magnetischen Prinzip arbeitet. Besonders bevorzugt umfassen die Bauelemente daher mindestens ein magnetoresistives Widerstandselement (AMR oder GMR) oder mindestens ein Hall-Element.The electronic automotive components are preferably electronic components of a wheel speed sensor, which operates in particular according to a magnetic principle. The components therefore particularly preferably comprise at least one magnetoresistive resistance element (AMR or GMR) or at least one Hall element.
Die Bauelemente enthalten vorzugsweise außerdem Bauelemente eines aktiven oder passiven Sensors. Unter einem aktiven Sensor wird ein Sensor verstanden, welcher aktive elektronische Bauelemente, wie z. B. Transistoren zur Sensorsignalaufbereitung, umfasst.The components preferably also include components of an active or passive sensor. An active sensor is understood to be a sensor which has active electronic components, such as eg. B. transistors for sensor signal processing includes.
Die Bauelemente umfassen weiterhin bevorzugt elektrische Leitungen, mit denen der Sensor mit einem elektronischen Bremsensteuergeräten verbunden werden kann, z. B. mit einem Bremsenssteuergerät welches ein universell einsetzbarer Kombiregler bestehend eine Elektronikeinheit (ECU) und ggf. eine angesteckte Hydraulikeinheit (HCU). Mit diesen Kombireglern können vielfältige Bremsen- und Fahrdynamik-regelungen bzw. Eingriffe, wie beispielsweise ABS, ABS plus, ASR oder ESP realisiert werden.The components further preferably comprise electrical lines, with which the sensor can be connected to an electronic brake control devices, for. B. with a brake control unit which a universally applicable combination controller consisting of an electronic unit (ECU) and possibly an infected hydraulic unit (HCU). With these combination controllers, a variety of braking and driving dynamics regulations or interventions, such as ABS, ABS plus, ASR or ESP can be realized.
