Description

Elektrische Widerstandselemente für Anlasser, Regler u. dgl. bestehen oft aus einzelner, mäander-oder wellenförmigen Einzelelementen von flacher Form. Zur einwandfreieren Halterung müssen die Widerstände oft auch außerhalb der Anschlußstellen noch befestigt werden. Hierzu hat man häufig Glimmer- od. dgl. Zwischenlagen verwendet. Dieser hat aber den Nachteil, daß er sich schwer verarbeiten oder verbiegen läßt. Auch ist es bekannt, blattförmige nachgiebige Widerstandselemente mit Isolierzwischenlagen zu einem Paket zusammenzupressen. Als Zwischenlagen hat man Schieferstäbe, Keramik oder Glimmer verwendet, die sich im allgemeinen teils wegen mangelnder Reinheit, teils wegen nicht genügender Temperatur- oder Druckfestigkeit nicht bewährt haben.There are electrical resistance elements for starters, regulators and the like often from individual, meandering or wave-shaped individual elements of flat shape. For proper mounting, the resistors often have to be outside of the connection points still to be attached. Mica or the like intermediate layers have often been used for this purpose. However, this has the disadvantage that it is difficult to process or bend. It is also known to use sheet-shaped, resilient resistance elements with insulating interlayers to compress into a package. Slate sticks and ceramics are used as intermediate layers or mica is used, which is generally partly due to a lack of purity, partly because of insufficient temperature or pressure resistance have not proven.

Die Erfindung hat die Aufgabe, eine Isolierstoffhalterung zu schaffen, die bei bester Temperaturbeständigkeit leicht den verschiedenen Isolier- und Halterungsaufgaben angepaßt werden kann, ohne daß die Kosten der bisher üblichen Halterung überschritten werden.The invention has the task of creating an insulating material holder, which, with the best temperature resistance, can easily handle the various insulation and mounting tasks can be adapted without exceeding the cost of the previously customary bracket will.

Für eine Isolierstoffhalterung von Widerstandselementen wird erfindungsgemäß ein Formteil verwendet, das zwar ebenfalls aus Glimmer, aber aus einer vorzugsweise mit einem hitzebeständigen Bindemittel versetzten Glimmerpülpe aufgebaut ist. Diese Halterung läßt sich in einfacher Weise aus dieser Glimmerpülpe in Blatt- oder Scheibenform herstellen, die leicht zu Hülsen od. dgl. gebogen werden können. Besonders vorteilhaft kann man aber auch Hülsen direkt als fertige Formteile herstellen, da die Formmasse vor Erhärtung leicht jeder vorgeschriebenen Form anpaßbar ist. Auch kann man bei entsprechender Wahl des Bindemittels Formteile, z. B. als Zwischenlagen od. dgl., herstellen, die allen an sie gestellten Anforderungen gerecht werden. Als wesentlicher Vorteil tritt hierbei hinzu, daß für die Herstellung der Glimmerpülpe Glimmerabfall oder Glimmerteile, die wegen ihres geringen Ausmaßes für die Verarbeitung nicht mehr verwendbar sind, benutzt werden können. Durch die Verwendung von Bindemitteln auf Siliziumbasis kann dabei eine große 'remperaturbeständigkeit mit derartigen Form- oder Preßteilen erreicht werden.According to the invention, for an insulating material holder for resistance elements a molded part is used, which is also made from mica, but preferably from a is built up with a heat-resistant binding agent mixed with mica pulp. These Holder can be easily made of this mica pulp in the form of a sheet or disk Manufacture that od easily into sleeves. Like. Can be bent. Particularly beneficial but you can also produce sleeves directly as finished molded parts, since the molding compound can easily be adapted to any prescribed shape before hardening. You can also use Appropriate choice of binder molded parts, e.g. B. as intermediate layers or the like., manufacture that meet all the requirements placed on them. As essential The advantage here is that mica waste is required for the production of the mica pulp or mica parts that are not suitable for processing because of their small size are more usable, can be used. Through the use of binders silicon-based can have a high temperature resistance with such Molded or pressed parts can be achieved.

In der Zeichnung sind einige Ausführungsbeispiele von Halterungen nach der Erfindung dargestellt.In the drawing are some exemplary embodiments of brackets shown according to the invention.

Fig. i zeigt eine Hülse, wie sie beispielsweise für flache Widerstandselemente verwendet werden kann; Fig. z zeigt einen als Preßformteil ausgebildeten Abstandsring; Fig.3 bis 8 zeigen einige Einbaubeispiele für Halterungen- nach der Erfindung.Fig. I shows a sleeve such as that used, for example, for flat resistance elements can be used; Fig. Z shows a spacer ring designed as a compression molded part; Fig. 3 to 8 show some installation examples for brackets according to the invention.

In den Fig. 3 und 4 werden Widerstandselemente i an ihren Enden mit Versteifungs- und Schutzblechen 2 versehen und gegen diese durch U-förmige Isolierhülsen 3 isoliert.In Figs. 3 and 4 resistor elements i are at their ends with Stiffening and protective plates 2 provided and against them by U-shaped insulating sleeves 3 isolated.

In Fig. 5 und 6 ist ein mäanderförmig ausgebildeter Widerstand 4 auf einem Flachstahlstab 5, der mit einer Hülse 6 nach der Erfindung versehen ist, angeordnet. Die Fig. 7 und 8 zeigen Gußeisenelemente 7, die durch erfindungsgemäß hergestellte Isolierscheiben 8 gegeneinander bzw. gegen Kontaktscheiben 9 isoliert sind.In Fig. 5 and 6 a meandering resistor 4 is on a flat steel bar 5, which is provided with a sleeve 6 according to the invention, arranged. 7 and 8 show cast iron elements 7, which are produced by the invention Insulating disks 8 are insulated from one another or from contact disks 9.
