Patentansprüche:Patent claims: 1. Elektrowerkzeug mit zu verschaltenden elektrischen Innenverbindungen, dadurch gekennzeichnet, daß die Steckeinheit als zentrale Stromverteilungsschiene (2) ausgebildet ist, die Steckanschlüsse für die erforderlichen elektrischen Bauelemente (z. B, 3, 4, 5, 6,, 8) aufweist und selbst mit einem Steckanschluß (1) versehen ist.1. Power tool with electrical to be interconnected Internal connections, characterized that the plug-in unit is designed as a central power distribution rail (2), the Plug-in connections for the required electrical components (e.g. 3, 4, 5, 6, 8) and themselves is provided with a plug connection (1). 2. Elektrowerkzeug nach Anspruch 1, dadurch gekennzeichnet, daß die Stromverteilungsschiene durch eine gedruckte Schaltung verkörpert ist2. Power tool according to claim 1, characterized characterized in that the power distribution bar is embodied by a printed circuit board 3. Elektrowerkzeug nach den Ansprüchen 1—2, dadurch gekennzeichnet, daß die Stromverteilungsschiene unmittelbar in das Gehäuse oder in die Handgriffschale integriert ist.3. Power tool according to claims 1-2, characterized in that the power distribution rail is directly integrated in the housing or in the handle shell. Die Herstellung der erforderlichen inneren elektrischen Verbindungen in Elektrowerkzeugen erfolgt bekanntlich mittels flexibler Leitungen und in der Regel manuell. Dementsprechend sind diese Verschaltungsarbeiten zeitaufwendig sowie zeitlich auch schiecht erfaßbar. Ebenso ist im Falle einer Reparatur der zum Lösen und Wiederverbinden erforderliche Aufwand beachtlich.Making the required internal electrical It is known that connections in power tools are made by means of flexible lines and as a rule manually. Accordingly, this interconnection work is time-consuming and also poor in terms of time detectable. Likewise, in the case of a repair, the effort required for loosening and reconnecting is required considerable. Es ist Aufgabe der Erfindung, unter Überwindung der Nachteile des Standes der Technik eine Lösung zu finden, die ein einfaches, zeitsparendes und zeitdefiniertes sowie betriebssicheres und reparaturfreundliches Herstellen der inneren Schaltverbindungen von Elektrowerkzeugen gewährleistet und die darüber hinaus die Lagerhaltung der benötigten Bauelemente begünstigt.The object of the invention is to provide a solution while overcoming the disadvantages of the prior art find a simple, time-saving and time-defined as well as reliable and repair-friendly production of the internal circuit connections of power tools guaranteed and which also favors the storage of the required components. Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Schaltverbindungen räumlich fest angeordnete Bestandteile einer Steckeinheit sind. Dabei hat es sich als besonders vorteilhaft erwiesen, die Steckeinheit als zentrale, selbst steckbare und Steckanschlüsse für die jeweils erforderlichen Bauelemente aufweisende Stromverteilungsschiene auszubilden. Derartige BauelementeThis object is achieved according to the invention in that the circuit connections are spatially fixed Components of a plug-in unit are. It has proven to be particularly advantageous to use the plug-in unit as central, self-plugging and plug-in connections for the respective required components having power distribution rail to train. Such components sind beispielsweise Kondensatoren, Ein- und Ausschalter, Potentiometer u, dgl.are for example capacitors, on and off switches, potentiometers and the like. In weiterer Ausgestaltung der Erfindung kann die Stromverteilungsschiene auch durch eine gedruckte Schaltung verkörpert sein,In a further embodiment of the invention, the power distribution rail can also be printed by a Circuit be embodied, Nach einem weiteren Gedanken der Erfindung ist die Stromverteilungsschiene unmittelbar in das Gehäuse des Elektrowerkzeugs oder in die Handpriffschale integriert und mit steckfähigen Verbindungselementen ausgestattetAccording to a further concept of the invention, the power distribution rail is directly in the housing of the power tool or in the hand test pan integrated and equipped with plug-in connection elements Der Gegenstand der Erfindung wird im nachstehenden anhand der Zeichnung näher erläutert Es zeigtThe object of the invention is explained in more detail below with reference to the drawing. It shows F i g. 1 die Seitenansicht eines Elektrowerkzeugs bei abgenommener Schalenhälfte,F i g. 1 the side view of a power tool with the shell half removed, Fig.2 die Ansicht eines mit der Steckeinheit ausgerüsteten Elektrowerkzeugs längs des Schnittes A-B. 2 shows the view of a power tool equipped with the plug-in unit along the section AB. Wie die Figuren erkennen lassen, sind mit einer zentralen, einen Steckanschluß 1 aufweisenden Stromverteilungsschiene 2 beispielsweise die folgenden Bauelemente leitend verbunden: Ein Schalter 3, ein Kondensator 4, ein Potentiometer 5 mit zugehörigem Elektronikbaustein, die Kohlebürsten 6 sowie ein Steckanschluß 7 für die Statorwicklung 8 des Antriebsmotors 9. Dabei ist die leitende Verbindung bzw. Kontaktierung der einzelnen Bauelemente mit der Stromverteilungsschiene 2 dadurch verwirklicht daß die einzelnen Bauelemente auf diese Schiene aufgesteckt sind.As the figures show, are with a central, a plug connector 1 having power distribution rail 2, for example, the following components are conductively connected: A switch 3, a Capacitor 4, a potentiometer 5 with an associated electronic component, the carbon brushes 6 and a Plug connection 7 for the stator winding 8 of the drive motor 9. The conductive connection or Contacting the individual components with the power distribution rail 2 is realized in that the individual components are attached to this rail. Um die als steckfähige Fahnen ausgebildeten Anschlußleitungen der Bürsten 6 und der Statorwicklung 8 auf einfache Weise mit der Stromverteilerschiene 2 vereinigen zu können, ist die selbe beim Ausführungsbeispiel abgewinkelt ausgebildet worden. Around the connecting lines of the brushes 6 and the stator winding, which are designed as plug-in lugs 8 to be able to combine in a simple manner with the power distribution busbar 2, the same has been formed angled in the exemplary embodiment. Es ist ohne weiteres ersichtlich, daß eine auf diese Weise verwirklichte Innenverschaltung von Elektrowerkzeugen und gegebenenfalls auch von anderen elektrischen Geräten auch sehr reparaturfreundlich ist, da defekte Bauelemente schnell un.I sicher austauschbar sind. Dies gilt insbesondere auch dann, wenn die Stromverteilungsschiene 2 durch eine gedruckte Schaltung verkörpert ist.It is readily apparent that an internal wiring of power tools realized in this way and, if necessary, is also very easy to repair from other electrical devices, because defective components can be replaced quickly and safely are. This is especially true when the power distribution rail 2 is through a printed circuit is embodied.
