Abstract

This device is installed in a device operated by electric motor, particularly a chain saw. The basic object is to design such an arrangement in such a manner that it can be installed into a device which is operated by electric motor with little wiring expenditure and compact construction. This object is achieved by the fact that an indicating lamp, a current-dependently operated switching element and connecting elements for the electrical connection to the conductors of a mains connection cable, on the one hand, and the feed lines to the device, on the other hand, are provided on a common socket element.

Description

Beschreibung:Description:

Die Erfindung bezieht sich auf eine im Oberbegriff des Anspruchs 1 bezeichnete Anordnung.The invention relates to one in the preamble of claim 1 designated arrangement.

Der Erfindung liegt die Aufgabe zugrunde eine solche Anordnung derart zu gestalten, daß sie bei kompaktem Aufbau mit geringem Verschaltungsaufwand in ein elektromotorisch betriebenes Gerät einbaubar ist.The invention is based on the object of such an arrangement to design that they are compact with little wiring effort in a device operated by an electric motor can be installed.

Die Lösung gelingt durch die im Anspruch 1 gekennzeichm Sn Merkmale. Vorteilhafte Weiterbildungen der Neuerung sind in den Unteransprü chen gekennzeichnet.The solution is achieved by the features marked Sn in claim 1. Advantageous further developments of the innovation are characterized in the subclaims.

Die Vorteile der Neuerung werden anhand der Beschreibung eines in der Zeichnung dargestellten vorteilhaften Ausführungsbeispiels näher erläutert.The advantages of the innovation are illustrated by the description of an in the advantageous embodiment illustrated in the drawing explained in more detail.

Fig. 1 zeigt die Schaltung der in der Überlastanzeigeeinrichtung unterzubringenden Bauelemente Fig. 2 zeigt die Seitenansicht einer erfindungsgemäß gestalteten Überlastanzeigeeinrichtung mit teilweise weggebrochenem Gehäuse.Fig. 1 shows the circuit to be accommodated in the overload indicator Components Fig. 2 shows the side view of an overload display device designed according to the invention with the case partially broken away.

In der Überlastanzeigeeinrichtung sind gemäß Figur 1 eine Anzeigelampe 1 mit einem Vorwiderstand 2, ein Heizwiderstand 3 und ein Thermoschalter 4 angeordnet. An die Anschlußelemente 5 und 6 werden die Leiter eines Netzanschlußkabels, an die Anschlußelemente 7 und 8 die Motorzuleitungen angeschlossen. Bei zu hoher Motorbelastung und dadurch erhöhtem Strom wird der Heizwiderstand so stark erwärmt, daß der Thermoschalter 4 schließt. Dann leuchtet die Anzeigelampe 1 auf, so daß die Überlastung optisch erkennbar ist.According to FIG. 1, there is an indicator lamp in the overload indicator 1 with a series resistor 2, a heating resistor 3 and a thermal switch 4 are arranged. To the connection elements 5 and 6, the conductors of a power cord are attached to the Connection elements 7 and 8 connected to the motor leads. If the engine load is too high and thereby increased current, the heating resistor is heated so much that the thermal switch 4 closes. Then the indicator lamp 1 lights up, so that the overload is visual is recognizable.

Fig. 2 zeigt den konstruktiven Aufbau einer neuerungsgemäß gestalteten Überlastanzeigeeinrichtung in vereinfachter Darstellung. Die Anzeigelampe 1 ist eine Glimmlampe. Die Anschlußelemente 7und 8 für die Leiter des Netzanschlußkabels sind als Schraubklemmen, die Anschlußelemente 5 und 6 für die Motorzuleitungen als Steckerstifte ausgebildet.Fig. 2 shows the structural design of an innovatively designed Overload display device in a simplified representation. The indicator lamp 1 is a glow lamp. The connection elements 7 and 8 for the conductors of the power cord are as screw terminals, the connection elements 5 and 6 for the motor leads as Connector pins formed.

Die Bauelemente 1 und 2 sind auf einer Seite des Sockelelements 9, die Bauelemente 3 bis 8 auf der anderen Seite angeordnet. Das Gehäuse 10 mit dem Linsenteil 11 ist einstückig aus farbig durchscheinendem Kunststoff hergestellt. Es wird über das Sockelelement 9 mit den Führungsansätzen 12 und 13 geschoben, bis die Nase 14 des Sockelelementes 9 in die Ausnehmung 15 des Gehäuses 10 einrastet. In dieser Lage sind die Anschlußelemente 5 bis 8 durch zugeordnete Ausnehmungen des Gehäuses 10 zugänglich.The components 1 and 2 are on one side of the base element 9, the components 3 to 8 arranged on the other side. The housing 10 with the Lens part 11 is made in one piece from colored translucent plastic. It is pushed over the base element 9 with the guide lugs 12 and 13 until the nose 14 of the base element 9 engages in the recess 15 of the housing 10. In this position, the connecting elements 5 to 8 are through associated recesses of the housing 10 accessible.

Die neuerungsgemäß Überlastanzeigeeinrichtung enthält bei kompaktem Aufbau nicht nur alle für ihre Funktion erforderlichen Bauelemente, sondern sie dient gleichzeitig als Anschlußblock zur Verbindung der Motorzuleitungen mit dem Netzanschlußkabel. Sie wird anstelle einer Lüsterklemme an passender Stelle der Außenwandung eines elektromotorisch betriebenen Gerätes derart eingebaut, daß der der Anzeigelampe 1 gegenüberliegende Linsenteil 11 frei sichtbar bleibt.According to the innovation, the overload display device contains a compact Construction not only of all the components required for their function, but them also serves as a connection block to connect the motor leads with the Power cord. Instead of a luster terminal, it is attached to the Outer wall of an electromotive device installed in such a way that the the lens part 11 opposite the indicator lamp 1 remains freely visible.
