Abstract
Description
Die Erfindung bezieht sich auf ein elastomerisches Verbindungsstück zur Herstellung einer elektrischen Verbindung zwischen zwei voneinander beabstandeten elektronischen Baugruppen mit einem elastischen Kontaktelement, in dem eine Vielzahl von voneinander isolierten, elektrisch leitenden Elementen eingebettet sind.The The invention relates to an elastomeric connector for manufacture an electrical connection between two spaced apart electronic assemblies with an elastic contact element, in which a plurality of mutually insulated, electrically conductive Elements are embedded.
Die Kontaktierung zweier elektronischer Baugruppen mittels redundanter elastomerischer Kontakte basiert auf dem Prinzip, daß gegenüberliegende Kontaktflächen auf den Baugruppen durch dazwischen eingebrachte Verbindungsstücke miteinander verbunden werden. Die Verbindungsstücke umfassen elastische Kontaktelemente, in denen eine Vielzahl von parallel angeordneten, voneinander isolierten, elektrisch leitenden Elementen, beispielsweise Drähten, eingebracht sind. Die elektrische Verbindung entsteht dadurch, daß die gegenüberliegenden Kontaktflächen durch die auf diesen Flächen zu liegen kommenden leitenden Elemente miteinander verbunden werden. Um eine leitende Verbindung herzustellen, müssen die Kontaktflächen genau gegenüberliegend positioniert und um ein definiertes Maß zusammengepreßt werden. Die elastischen Kontaktelemente werden dabei in einem Halter mechanisch geführt.The Contacting of two electronic modules by means of redundant elastomeric contacts based on the principle that opposite contact surfaces on the assemblies by intervening connectors with each other get connected. The connecting pieces comprise elastic contact elements, in which a plurality of parallel arranged, isolated from each other, electrically conductive elements, such as wires introduced are. The electrical connection is created by the fact that the opposite contact surfaces the on these surfaces to be connected to lying conductive elements. To make a conductive connection, the contact surfaces must be accurate opposite be positioned and compressed by a defined amount. The elastic contact elements are mechanically in a holder guided.

Die gegenüberliegenden Kontaktflächen müssen sehr genau positioniert werden. Dies setzt eine präzise Fertigung von Halter und Platinenaufnahmen in den Baugruppen voraus. Ein Einsatz des Verbindungsstücks zwischen Baugruppen, deren position zueinander mit Toleranzen in X-, Y- und Z-Richtung behaftet sind, ist so nicht möglich. Bei einer X-Verschiebung der Baugruppen geht ein signifikanter Bereich der Kontaktflächen verloren. Dies führt zu einer Erhöhung des Kontaktwiderstands, zu einer Verringerung der Strombelastbarkeit und im Extremfall zu einem Kurzschluß benachbarter Kontaktflächen.The opposite Contact surfaces must be very be accurately positioned. This requires a precise manufacturing of holder and Board receptacles in the modules ahead. An insert of the connector between Assemblies whose position to each other with tolerances in X, Y and Z direction are affected, so is not possible. At an X-shift of the assemblies, a significant area of the contact surfaces is lost. this leads to to an increase the contact resistance, to a reduction of the current carrying capacity and in extreme cases to a short circuit of adjacent contact surfaces.
Der Erfindung liegt daher die Aufgabe zugrunde, ein elastomerisches Verbindungsstück zu schaffen, bei dem die zu kontaktierenden Baugruppen in ihrer Position zueinander Verschiebungen in X-, Y- und Z-Richtung aufweisen dürfen.Of the The invention is therefore based on the object, an elastomeric joint to create, in which the assemblies to be contacted in their Position to each other have displacements in the X, Y and Z direction allowed to.
Gelöst wird diese Aufgabe mit den Merkmalen des Hauptanspruchs. Für die sichere Kontaktierung ist ein Kraftfluß zwischen den Leiterplatten der beiden elektronischen Baugruppen und dem elastischen Kontaktelement erforderlich, um das Kontaktelement an die Kontaktflächen zu pressen. Dieser Kraftfluß wird nach der Erfindung aufgetrennt, indem an jedem der beiden, den Baugruppen zugewandten Endbereiche des Kontaktelements ein eigener Halter für die Verbindung mit der jeweiligen Baugruppe befestigt ist. Mit den beiden separaten Haltern ist das Kontaktelement an jedem seiner beiden, den Baugruppen zugewandten Endbereiche fixiert. Jeder der beiden Halter wird mit der jeweiligen Baugruppe fest verbunden, beispielsweise angeschraubt, und erzeugt so den erforderlichen Anpreßdruck. Die Überlänge des elastischen Kontaktelements gegenüber dem Abstand der Baugruppen ermöglicht eine Verschiebung der Position der Halter zueinander in X-, Y- und Z-Richtung. Damit ist die Kontaktierung im Toleranzbereich der Baugruppenpositionen möglich. Durch die Möglichkeit, die zu kontaktierenden Baugruppen in einem weiten Bereich frei zueinander zu positionieren, kann die mechanische Aufnahme der Baugruppen kostengünstig mit großen Toleranzen gefertigt werden. Der große Vorteil der bisherigen Verbindungsstücke, nämlich die Unempfindlichkeit gegenüber mechanischem Schock und Vibration, bleibt dabei vollständig erhalten.Is solved this task with the features of the main claim. For the safe Contacting is a power flow between the printed circuit boards of the two electronic assemblies and the elastic Contact element required to press the contact element to the contact surfaces. This power flow is separated according to the invention, by at each of the two, the assemblies facing end portions of the contact element a separate holder for the connection is attached with the respective assembly. With the two separate Holders is the contact element on each of its two, the assemblies fixed facing end portions. Each of the two holders will be with the respective module firmly connected, for example screwed, and thus generates the required contact pressure. The excess length of the elastic contact element with respect to the distance of the modules allows a shift of the position of the holder to each other in X-, Y- and Z-direction. Thus, the contact is in the tolerance range of the module positions possible. By the possibility, the assemblies to be contacted in a wide range freely to each other To position the mechanical recording of the assemblies can be cost effective huge Tolerances are manufactured. The big advantage of the previous connectors, namely the Insensitivity to mechanical shock and vibration, remains fully intact.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.advantageous Embodiments of the invention are described in the subclaims.
Die Fixierung des Kontaktelements im jeweiligen Holder kann auf vielfältige Weise erfolgen. Die Halter können beispielsweise mit dem Kontaktelement verklebt oder verpreßt sein. Dabei kommt beim Verpressen vorzugsweise ein spezifisch ausgeformter Halter zum Einsatz.The Fixation of the contact element in the respective holder can in many ways respectively. The holders can be glued or pressed, for example, with the contact element. In this case, preferably a specifically shaped during pressing Holder used.
Gemäß einer bevorzugten Weiterbildung der Erfindung sind wenigstens einer der, den Baugruppen zugewandten Endbereiche des Kontaktelements und der entsprechende Halter durch spezifische Formgebung miteinander befestigt. Diese Befestigung kann beispielsweise realisiert werden, indem das elastische Kontaktelement an wenigstens einem der, den Baugruppen zugewandten Endbereichen eine Verdickung aufweist und die Verdickung von dem Halter umschlossen ist. Dabei ist es günstig, wenn die Verdickung von dem der Baugruppe zugewandten Ende beabstandet ist und das elastische Kontaktelement an diesem Ende einen geringeren Querschnittsdurchmesser als die Verdickung aufweist.According to one preferred embodiment of the invention are at least one of, the assemblies facing end portions of the contact element and the corresponding holder attached by specific shaping together. This attachment can be realized, for example, by the elastic Contact element on at least one of the assemblies facing End regions has a thickening and the thickening of the Holder is enclosed. It is beneficial if the thickening is spaced from the assembly facing the end and the elastic contact element at this end a smaller cross-sectional diameter than the Has thickening.
Wenn das elastische Kontaktelement von mehreren Einzelelementen gebildet ist, erhöht sich die Flexibiltät des Kontaktelements und es lassen sich neben Verschiebungen in X-, Y- und Z-Richtung sogar Rotationen der beiden Baugruppen zueinander ausgleichen.If the elastic contact element formed by a plurality of individual elements is increased Flexibility of the contact element, and besides displacements in X-, Y- and Z-direction even compensate for rotations of the two modules to each other.
