Abstract

The invention relates to a method of producing an electrically conductive adhesive connection which consists in that a semifinished article is created by coating, preferably by a brushing method, a metallic woven or braided material with a thermocurable impregnating resin and inserting this prepreg between the parts to be connected, preferably as a cut-to-size piece, and curing it under pressure and heat.

Description

Elektrisch leitende KlebeverbindungElectrically conductive adhesive connection

Die Erfindung bezieht sich auf eine elektrisch leitende Klebeverbindung zwischen zwei leitenden Teilen.The invention relates to an electrically conductive adhesive connection between two conductive parts.

Derartige Klebeverbindungen ließen sich mit Klebern, die leitende Beimischungen aufweisen, durchführen. Die der gangswiderstände und die Schichtdicke sind hier jedoch nicht genau zu definieren. Der vorliegenden Erfindung liegt somit die AuFibe zugrunde, eine Klebeverbindung der obengenannten Art hcrzustcllcn, bei der die Dicke der Klebschicht und auch der Übergangswiderstand vorherbestimmbar sind. Dies wird auf einfache Weise dadurch erreicht, daß zwischen den leitenden Teilen ein leitendes Gitter angeordnet ist, das zwischen den Gitterstäben Klebemittel, vorzugsweise Reaktionsharz, aufweist, das mit den Teilen in Verbindung steht. Hier hat sich ein Verfahren als vorteilhaft erwiesen, das darin besteht, daß ein mit einer wärmehärtenden Reaktionsharzschicht versehenes metallenes Gewebe oder Geflecht zwischen die Teile gelegt wird und hernach unter solchem Drlck und Wärme ausgehärtet wird, daß eine leitende Brücke zwischen den Teilen über das Gewebe hergestcllt ist. Das so hergestellte trockene oder halb trockene Metallgewebe-Prepreg ist leicht stanzbar und schneidfähig. Außerdem erlaubt die gute Verzugsfreiheit auch die Herstellung und Manipulierung komplizierter Zuschnitte. Beim anschließenden Preßvorgang wird eventuell überschüssiger geschmolzener Kleber solange aus der Klebefuge verdrängt oder eingeebnet, bis das berührte Drahtgewebe eine weitere Annäherung verhindert, d.h. das metallische Trägergewebe wird als Abstandselement benutzt. Minimale Schichtdicken bis zu 0,05 mm sind ohne Probleme zu garantieren. Dadurch, daß La 2 Syr / 05.02.1985 die metallischen Trägergewebe an beiden Teilen mehr oder weniger ohne Zwischenschaltung von Kleber direkt anliegen, ist das Trägergewebe als sicheres Stromübertragungselement benutzbar. Als vorteilhaft hat sich erwiesen, wenn das meist sehr dünne metallische Gewebe oder Geflecht im Streichverfahren mit einem reaktionsfähigen, wärmehärtenden Kleber z.B. auf Epoxibasis beschichtet wird.Such adhesive connections can be made with adhesives, the conductive Have admixtures, carry out. The resistance and the layer thickness however, cannot be precisely defined here. The present invention thus lies the underlying purpose of creating an adhesive connection of the type mentioned above which allows the thickness of the adhesive layer and also the contact resistance to be determined in advance are. This is achieved in a simple manner that between the conductive Divide a conductive grid is arranged, the adhesive between the bars, preferably reaction resin, which is in connection with the parts. here a method has proven to be advantageous, which consists in that a with metallic fabric or braid provided with a thermosetting reaction resin layer is placed between the parts and then cured under such pressure and heat that a conductive bridge between the parts is established via the tissue. The dry or semi-dry metal mesh prepreg thus produced is light punchable and cutable. In addition, the good freedom from distortion also allows production and manipulation of complicated blanks. During the subsequent pressing process Any excess melted adhesive is displaced from the adhesive joint for as long or leveled until the touched wire mesh prevents further approach, i.e. the metallic carrier fabric is used as a spacer element. Minimal layer thicknesses up to 0.05 mm can be guaranteed without any problems. Because La 2 Syr / 05.02.1985 the metallic carrier fabric on both parts more or less without interposition If the adhesive is in direct contact with it, the carrier fabric acts as a safe power transmission element usable. It has proven to be advantageous if the mostly very thin metallic Weave or braid in the brushing process with a reactive, thermosetting Adhesive is coated e.g. on an epoxy basis.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und das Verfahren näher erläutert.An exemplary embodiment according to the invention is illustrated with the aid of the drawing described and the process explained in more detail.

Es zeigen: Fig. 1 in perspektivischer Darstellung die einzelnen Teile vor dem Zusammenfügen und Fig. 2 eine Schnittdarstellung der Klebeverbindung nach Durchführung des Verfahrens.The figures show: FIG. 1 the individual parts in a perspective illustration before assembly and FIG. 2 shows a sectional view of the adhesive connection after Implementation of the procedure.

Zwischen die beiden zu verbindenden Teile 1 und 2 wird das Gewebe oder Geflecht 3, das mit Reaktionsharzschichten 4 und 5 auf beiden Seiten versehen ist, eingefügt.Between the two parts 1 and 2 to be connected is the fabric or braid 3, which is provided with reactive resin layers 4 and 5 on both sides is inserted.

Die Schicht kann durch Streichen oder Tauchen aufgebracht werden, wobei sich das Streichen als vorteilhafter erwiesen hat. Nach Zusammenfügen der Teile 1, 2 und der wischenschaltung des leitenden Gitters ergibt sich die aus Fig. 2 ersichtliche Konstellation. Die Gitterstäbe ö des Gewebes oder Geflechtes 3 liegen direkt an den Teilen 1, 2 und zwischen den Gitterstäben befindet sich das von den Schichten 4, 5 hier hereingedrückte Epoxiharz 7, das die mechanische Verbindung der beiden Teile 1, 2 übernimmt. Da die Gitterstäbe 6 direkt an den Teilen 1 und 2 anliegen, ist auch eine sichere elektrische Verbindung gewährleistet. Die Verbindung kann nicht nur für Masseverbindungen in elektrischen Geräten, sondern unter gewissen Umständen auch zur Befestigung von Kontaktauflagen auf Kontaktträgern Verwendung finden.The layer can be applied by brushing or dipping, painting has proven to be more advantageous. After joining the Parts 1, 2 and the wiping circuit of the conductive grid results from Fig. 2 visible constellation. The bars of the fabric or mesh 3 are located directly on parts 1, 2 and between the bars is that of the Layers 4, 5 here pressed in epoxy resin 7, which is the mechanical connection of the two parts 1, 2 takes over. Since the bars 6 directly on the parts 1 and 2 are present, a safe electrical connection is also guaranteed. The connection can not only be used for ground connections in electrical devices, but under certain conditions Can also be used for fastening contact pads on contact carriers Find.
