Description

Die Frontrahmen und Frontringe der- Gehäuse von Meßgeräten werden möglichst schmal bemessen, um den zur Verfügung stehenden Raum weitgehend zur Unterbringung des Meß-,verkes und der Skala ausnutzen zu können. Kleinere Gerätegehäuse stellt man einteilig, beispielsweise ganz aus Isolierpreßstoff her, um den Raum für die Unterbringung der Verbindungsteile zur Verbindung von Frontrahmen und Gehäusemantel einzusparen. Bei größeren Gehäuseabmessungen ist das jedoch häufig wegen der hohen Werkzeugkosten nicht möglich. Bei elektrischen Meßgeräten ist es auch aus magnetischen Gründen meist erforderlich, die Gehäusewandungen aus Eisenblech herzustellen. In ,diesen Fällen ist es außerdem erforderlich, den Rahmen so mit dem Gehäuse zu verbinden, daß das Eindringen von Staub und Feuchtigkeit mit Sicherheit verhindert wird.The front frame and front rings of the housing of measuring devices are Measured as narrow as possible to largely accommodate the space available to be able to use the measuring, verkes and the scale. Smaller device housing represents one piece, for example, made entirely of pressed insulating material to provide the space for the Accommodation of the connecting parts for connecting the front frame and housing shell to save. In the case of larger housing dimensions, however, this is often due to the high Tool costs not possible. In the case of electrical measuring instruments, it is also made of magnetic ones Reasons usually necessary to make the housing walls from sheet iron. In , in these cases it is also necessary to connect the frame to the housing in such a way that that the ingress of dust and moisture is prevented with certainty.

Die Erfindung bezweckt, einen Frontrahmen aus Isolierpreßstoff oder aus Metall auf einen Gehäusemantel aus Metall diesen Anforderungen entsprechend zu befestigen, wobei für die Unterbringung der Verbindungselemente ein Minimum an' Raum erforderlich ist. Erfindungsgemäß sind flache Verbindungsteile in dem Frontring eingepreßt oder eingegossen und. mit dem Gehäusemantel, gegebenenfalls unter Zwischenschaltung einer Dichtung, vorzugsweise durch Punktschweißung, verbunden.The invention aims to provide a front frame made of molded insulating material or made of metal on a housing made of metal to meet these requirements to be attached, whereby a minimum of ' Space is required. According to the invention, flat connecting parts are in the front ring pressed in or cast and. with the housing jacket, if necessary with the interposition a seal, preferably connected by spot welding.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung. Mit i ist der Frontrahmen oder Frontring, .-mit 2 der Blechmantel des Gehäuses bezeichnet, 3 ist ein eingelegter Dichtungsring, 4 sind dünne Blechstreifen, die bei der Herstellung des Frontrahmens aus Isolierpreßstoff in diesen mit eingepreßt oder beider Herstellung aus Metall mit eingegossen werden. 5 ist die Glasscheibe des Instrumentengehäuses. Die Verbindung der Blechstreifen 4 mit dem Gehäusemantel 2 erfolgt beispielsweise durch Punktschweißung, nachdem durch ein geeignetes Werkzeug der Frontrahmen gegen den Dichtungsring 3 gepreßt wurde.The drawing illustrates an embodiment of the invention. The front frame or front ring is denoted by i, the sheet metal jacket of the housing is denoted by 2, 3 is an inserted sealing ring, 4 are thin sheet metal strips that are used during manufacture the front frame made of molded insulating material is pressed into it or during manufacture made of metal to be cast in. 5 is the glass pane of the instrument housing. The connection of the sheet metal strips 4 to the housing jacket 2 takes place, for example by spot welding, after the front frame has been counteracted with a suitable tool the sealing ring 3 was pressed.

Das Wesentliche der Erfindung ist also das Einpressen oder Eingießen eines möglichst flachen Verbindungsstreifens 4 in .den Frontrahmen i und: die Verwendung dieses Streifens zur Herstellung der festen Verbindung mit dem Gehäusemantel 2, vorzugsweise durch Punktschw-eißung.The essence of the invention is therefore the pressing in or pouring in a connecting strip 4 that is as flat as possible in .den front frame i and: the use this strip for establishing the fixed connection with the housing jacket 2, preferably by spot welding.
