Abstract

In order to simplify the production of an attaching device for electrical resistors, for example bias resistors for fans in motor vehicles, the resistors forming an assembly with electrical plug connections, the plug connections (7) are constructed integrally with stamped parts (4) which extend into the ceramic body of the resistance body (2) on the one hand and into a plastic plug housing (3) on the other hand, and are at the same time used as electrical connections and for mechanical attachment of the resistance body (2). In this case, those stamped parts (4,8) which in each case lie in a plane are initially produced as a cohesive stamped matrix, are then connected to the resistance body (2) and its resistance wires and, finally, are subsequently electrically isolated from one another by areas (11, 12) being cut out. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Befestigungsvorrichtung für elektrische Widerstände, z.B. Vorwiderstände für Gebläse in Kraftfahrzeugen, wobei die Widerstände mit elektrischen Steckverbindungen eine Baugruppe bilden. Sie betrifft auch ein Verfahren zur Herstellung der Befestigungsvorrichtung.The invention relates to a fastening device for electrical resistors, e.g. Series resistors for blowers in motor vehicles, the resistors forming an assembly with electrical plug connections. It also relates to a method for manufacturing the fastening device.

Solche Keramikwiderstände werden in der Regel auf einer Grundplatte durch Haltewinkel mechanisch befestigt. Die von der mechanischen Befestigung getrennten elektrischen Verbindungen zur Schnittstelle (Stecker) werden mittels Kupferleitungen hergestellt, an die Flachstecker o.dgl. gekrimpt werden. Zur Herstellung einer solchen Widerstands-Baugruppe wird viel Handarbeit und Zeit benötigt.Such ceramic resistors are usually mechanically attached to a base plate using brackets. The electrical connections to the interface (plug) separated from the mechanical fastening are made by means of copper cables, to the flat plug or the like. be crimped. A lot of manual work and time is required to produce such a resistor assembly.

Der Erfindung liegt die Aufgabe zugrunde, eine im Aufbau und in der Herstellung vereinfachte Befestigungsvorrichtung für elektrische Widerstände zu schaffen.The object of the invention is to create a fastening device for electrical resistors that is simplified in terms of structure and manufacture.

Diese Aufgabe wird bei einer Befestigungsvorrichtung der genannten Gattung dadurch gelöst, daß die Steckverbindungen einstückig mit Stanzteilen ausgebildet sind, die sich in den Keramikkörper des Widerstandes einerseits und in ein Steckergehäuse aus Kunststoff andererseits erstrecken und gleichzeitig als elektrische Verbindungen und zur mechanischen Befestigung des Widerstandskörpers dienen.This object is achieved in a fastening device of the type mentioned in that the plug connections are formed in one piece with stamped parts which extend into the ceramic body of the resistor on the one hand and into a plug housing made of plastic on the other hand and at the same time serve as electrical connections and for mechanical fastening of the resistor body.

Das erfindungsgemäße Verfahren zur Herstellung dieser Befestigungsvorrichtung besteht darin, daß die jeweils in einer Ebene liegenden Stanzteile zunächst als eine zusammenhängende Stanzmatrix hergestellt, dann mit dem Widerstandskörper und dessen Widerstandsdrähten verbunden und schließlich nachträglich durch Freischnitte elektrisch voneinander getrennt werden.The method according to the invention for producing this fastening device consists in that the stamped parts lying in one plane are first produced as a coherent stamping matrix, then with the resistance body and whose resistance wires are connected and finally electrically separated from one another by free cuts.

Die Stanzmatrix dient als Grundplatte, die nun als separates Bauteil nicht mehr erforderlich ist. Sie ersetzt ferner den bisher notwendigen Haltewinkel. Außerdem dient sie als Verbindung zur Schnittstelle (Stecker). Ferner dient die Matrix als Steckverbinder zur Widerstandsbaugruppe und als direkter Steckverbinder zum Motor. Es entstehen keine Übergangswiderstände an Krimpverbindungen, da solche nicht mehr vorhanden sind und in der Vergangenheit häufig Gefahren- und Störstellen waren. Es werden keine flexiblen Teile mehr benötigt, da die Matrix mit dem Keramikkörper verbunden ist; vielmehr wird eine exakte starre Verlegung der elektrischen Leiter ermöglicht. Die rationelle Fertigung ist ebenfalls ein wesentlicher Vorteil.The punch matrix serves as a base plate, which is no longer required as a separate component. It also replaces the previously required bracket. It also serves as a connection to the interface (plug). The matrix also serves as a connector to the resistor assembly and as a direct connector to the motor. There are no contact resistances on crimp connections, as there are no longer any and there were often danger and fault points in the past. Flexible parts are no longer required because the matrix is connected to the ceramic body; rather, an exact rigid laying of the electrical conductors is made possible. The rational production is also a major advantage.

Die Fig. 1 bis 3 zeigen den komplettierten Widerstandsbauteil 1, der im wesentlichen aus einem Widerstandskörper 2 aus Keramik (siehe auch Fig. 6), einem Steckergehäuse 3 aus Kunststoff und Stanzteilen 4 besteht, von denen zwei vorgesehen sind. Eines der Stanzteile ist stark vergrößert in Fig. 4 dargestellt.1 to 3 show the completed resistance component 1, which essentially consists of a resistance body 2 made of ceramic (see also FIG. 6), a plug housing 3 made of plastic and stamped parts 4, two of which are provided. One of the stamped parts is strong shown enlarged in Fig. 4.

Das Steckergehäuse 3 weist eine einstückig mit ihm ausgebildete Platte 5 auf, mit der der ganze Widerstandsbauteil 1 im Luftkanal eines Gebläses, z.B. in einem Kraftfahrzeug, befestigt wird. Wie in den Fig. 1 und 3 gezeigt, kann auch eine Mikrotemperatursicherung (MTS) 6 vorgesehen sein.The connector housing 3 has a plate 5 formed integrally with it, with which the entire resistance component 1 in the air duct of a blower, e.g. in a motor vehicle. As shown in FIGS. 1 and 3, a micro temperature fuse (MTS) 6 can also be provided.

Jedes Stanzteil 4 (siehe Fig. 4) ist einstückig mit Steckverbindungen 7 aus Blech ausgestanzt und weist langgestreckte Teilstücke 8 auf und wird in entsprechende Nuten 9 bzw. Schlitze 10 des Widerstandskörpers 2 eingesetzt und zementiert, nachdem die nicht dargestellten Widerstandsdraht-Wicklungen aufgebracht und verbunden worden sind.Each stamped part 4 (see FIG. 4) is stamped in one piece with plug connections 7 from sheet metal and has elongated sections 8 and is inserted and cemented in corresponding grooves 9 or slots 10 of the resistance body 2 after the resistance wire windings, not shown, have been applied and connected have been.

Nach dem Einsetzen der beiden Stanzteile 4, die eine selbsttragende Konstruktion des Widerstandsbauteils 1 bewirken und gleichzeitig die elektrische Verbindung bilden, werden die einzelnen elektrischen Steckverbindungen 7 dadurch voneinander elektrisch getrennt, daß Freischnitte zwischen den jeweiligen punktierten Linien 11 bzw. 12 (siehe Fig. 4) hergestellt werden, wobei Löcher 13 zum Lokalisieren in der entsprechenden Stanzvorrichtung dienen.After the insertion of the two stamped parts 4, which bring about a self-supporting construction of the resistance component 1 and at the same time form the electrical connection, the individual electrical plug connections 7 are electrically separated from one another by free cuts between the respective dotted lines 11 and 12 (see FIG. 4 ) are produced, holes 13 being used for localization in the corresponding punching device.

An jedem Stanzteil 4 ist noch eine ausgeklinkte Öse 14 für den Anschluß eines Entstörungskondensators (nicht dargestellt) vorgesehen (siehe auch Schnittdarstellung in Fig. 5).On each stamped part 4, a notched eyelet 14 is also provided for connecting an interference suppression capacitor (not shown) (see also the sectional view in FIG. 5).
