Abstract
Description
Die Erfindung bezieht sich auf ein elektronisches Gerät, insbesondere in einem Kraftfahrzeug, mit einem in einem Gehäuse angeordneten elektronischen Bauteil, das eine oder mehrere Anschlussfahnen aufweist, und mit einem in das Gehäuse führenden Kabel, das von einer entsprechenden Anzahl von Leitungen gebildet ist.The invention relates to an electronic device, especially in a motor vehicle, with one in one Housing arranged electronic component, the one or has several connecting lugs, and with one in the housing leading cable by an appropriate Number of lines is formed.
Bei diesem Gerät kann es sich zum Beispiel um einen Sensor, insbesondere um einen Hall-Effekt-Sensor handeln, der u. a. zur Raddrehzahlbestimmung innerhalb eines Systems zur Antiblockierregelung oder als Gurtschlossschalter eingesetzt wird. Das Kabel kann dabei auch in der Weise ausgebildet sein, dass eine Steckerverbindung aufweist, wobei eines der Steckerelemente gehäusefest und das andere Steckerelement, mit dem ersten verbindbar, kabelfest ist.For example, this device can be a sensor, in particular a Hall effect sensor, the u. a. for determining wheel speed within a system for anti-lock control or as a seat belt buckle switch is used. The cable can also be used in the Be designed such that it has a plug connection, one of the connector elements being fixed to the housing and the other connector element, connectable to the first, cable-fixed is.
Derartige Sensoren müssen robust aufgebaut sein, in einem
weiten Temperaturbereich funktionieren und mechanisch
stabil sein. Außerdem sollen sie leicht und kostengünstig
herzustellen sein.
Bisher wurden solche Sensoren so aufgebaut, dass die dafür
notwendigen elektronischen Bauteile auf einem Leiterbahnen
bildenden metallischen Rahmen aufgeschweißt wurden.
Da eine Schweißverbindung von sehr vielen Parametern
bestimmt wird, traten bei der Montage mit Robotern häufig
Fehler auf, so dass der Ausschuss nur bei sehr sorgfältiger
Überwachung der Schweißanlage klein gehalten werden
konnte.Such sensors must have a robust design, function in a wide temperature range and be mechanically stable. In addition, they should be easy and inexpensive to manufacture.
So far, such sensors have been constructed in such a way that the electronic components required for this purpose have been welded onto a metallic frame forming conductor tracks. Since a welded connection is determined by a large number of parameters, errors often occurred during assembly with robots, so that the rejects could only be kept to a minimum if the welding system was monitored very carefully.
Um diesem Nachteil abzuhelfen und außerdem weiterhin die oben genannten Forderungen zu erfüllen, wird vorgeschlagen, dass jede Anschlussfahne mit der ihr zugeordneten Leitung im Gehäuse mittels einer Quetschverbindung elektrisch leitend verbunden ist.To remedy this disadvantage and also continue to to meet the above requirements, it is proposed that each connection lug with the one assigned to it Cable in the housing electrically by means of a crimp connection is conductively connected.
Damit wird zunächst erreicht, das auf einen metallischen Rahmen verzichtet werden kann, was den Aufbau des Geräte deutlich vereinfacht. Besonders vorteilhaft ist aber, dass die Quetschverbindung ohne hohen Überwachungsaufwand von einem Roboter hergestellt werden kann, da die Güte der Quetschverbindung nur von wenigen leicht einhaltbaren Parametern bestimmt wird.This is achieved first on a metallic Frame can be dispensed with, which is the construction of the device significantly simplified. However, it is particularly advantageous that the crimp connection without high monitoring effort can be made by a robot because of goodness the crimp connection only by a few easily maintainable Parameters is determined.
Typischerweise besteht eine Quetschverbindung aus einer Quetschhülse, die in ihrem Ursprungszustand eine zu einer Seite offene Halbschale bildet, in der das zu kontaktierende Leitungs- oder Anschlussfahnenende eingelegt wird. Zur Herstellung einer Verbindung werden die Seitenwände der Halbschale definiert verformt, beispielsweise nach innen gedrückt, wobei die Enden in der verformten Hülse festgeklemmt werden und eine elektrisch leitende Verbindung mit der Hülse eingehen. Eine solche Quetschverbindung wird auch als Verkrimpung bezeichnet.Typically, a crimp connection consists of a Crimp sleeve that is one to one in its original state Forms an open half-shell in which the to be contacted Cable or connecting lug end is inserted. The side walls are used to create a connection the half-shell is deformed in a defined manner, for example after pressed inside, the ends in the deformed sleeve be clamped and an electrically conductive connection with the sleeve. Such a crimp connection is also called crimping.
Als Weiterbildung der Erfindung wird vorgeschlagen, dass jede Quetschverbindung aus zwei elektrisch leitend miteinander verbundenen Quetschhülsen besteht, wobei die eine Quetschhülse das Ende der Anschlussfahne und die andere das Ende der Leitung aufnimmt. Vorzugsweise sind die beiden Quetschhülsen in axialer Richtung hintereinander angeordnet.As a development of the invention, it is proposed that each crimp connection from two electrically conductive with each other connected crimp sleeves, the one Crimp sleeve the end of the terminal lug and the other picking up the end of the line. Preferably, the two crimp sleeves one behind the other in the axial direction arranged.
Die Miniaturisierung von elektronischen Bauteilen ist sehr weit fortgeschritten, so dass z. B. in einem Baustein ein magnetfeldsensitives Element sowie die nötigen Ansteuerelemente angeordnet sind. Einige Bauteile, wie z. B. ein Kondensator mit hoher Kapazität, müssen wegen ihrer Größe aber immer noch gesondert aufgebaut werden. Für einen solchen Fall wird vorgeschlagen, dass in den Quetschhülsen für die Leitungen außerdem die Anschlussfahnen eines weiteren elektronischen Bauteils aufgenommen sind.The miniaturization of electronic components is very advanced, so that e.g. B. in a block a magnetic field sensitive element and the necessary Control elements are arranged. Some components, such as B. a capacitor with high capacitance, because of their Size but can still be built up separately. For In such a case it is proposed that in the Crimp sleeves for the cables also the connection lugs of another electronic component added are.
Bei dem bisher vorgeschlagen Aufbau kann die Verbindung der Bauteile mittels der Quetschverbindung zunächst außerhalb des Gehäuses erfolgen. Anschließend werden die vorbereiteten und zusammengebauten Elemente in eine aus einem elektrisch nichtleitenden Material, vorzugsweise Kunststoff, hergestellte Schale mit einer oder mehreren Rillen gelegt, so dass die einzelnen Quetschverbindungen voneinander elektrisch isoliert liegen. Außerdem können in der Schale Vertiefungen für das erste und ggf. für die weiteren Bauteile vorgesehen sein.With the structure proposed so far, the connection can the components by means of the crimp connection initially outside of the housing. Then the prepared and assembled elements into one an electrically non-conductive material, preferably Plastic, shell made with one or more Grooves laid so that the individual crimp connections are electrically isolated from each other. You can also recesses in the bowl for the first and possibly for the other components may be provided.
Abschließend wird die Schale mit von einem im Spritzgussverfahren hergestellten Kunststoffmantel zur Bildung des. Gehäuses umgeben.Finally, the shell is made using an injection molding process manufactured plastic jacket to form the. Housing.
