Abstract

The electric power tool has its internal current supply leads made of rigid conductors. This avoids the necessity for time consuming wiring operations during manufacture and repairs. The live' conductor (2) is profiled and has tags and sockets or similar to allow the various components potentiometer, capacitor, carbon brushes, stator winding connectors, switch etc. to be plugged or fixed to it without wires. Rigid conductors also simplfy assembly and increase reliability. The rigid conductors are mechanically connected to the inside of the casing of the tool.

Description

Elektrowerkzeug Power tool

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 seitlich auch schlecht erfaßbar. Ebenso ist im Falle einer Reparatur der zum Lösen und Wiederverbinden erforderliche Aufwand beachtlich.Making the necessary internal electrical connections in power tools is known to take place by means of flexible lines and in the Usually manual. Accordingly, this interconnection work is time consuming as well also difficult to grasp laterally. Likewise, in the event of a repair, the one to loosen and reconnecting required considerable effort.

Es ist Aufgabe der Erfindung, unter Vberwindung 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, 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.It is the object of the invention, while overcoming the disadvantages of the Prior art to find a solution that is simple, time-saving and Time-defined, operationally reliable and repair-friendly production of the internal circuit connections of power tools guaranteed and beyond favors the storage of the required components, This task 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 proved the plug-in unit as a central, self-pluggable and plug-in connections for to form the respective required components having power distribution rail.

Derartige Bauelemente sind beispielsweise Kondensatoren, Ein- und Ausschalter, Potentiometer u.dgl.Such components are, for example, capacitors, inputs and Off switch, potentiometer, etc.

In weiterer Ausgestaltung der Erfindung kann die Stromverteilungsschiene auch durch eine gedruckte Schaltung verkörpert sein, Nach einem weiteren Gedanken der Erfindung ist die Stromverteilungsschiene unmittelbar in das Gehäuse des Elektrowerkzeugs oder in die Randgriffschale integriert und mit steckfähigen Verbindungselementen ausgestattet.In a further embodiment of the invention, the power distribution rail also be embodied by a printed circuit board, after another thought According to the invention, the power distribution rail is directly in the housing of the power tool or integrated into the edge grip and with plug-in connecting elements fitted.

Der Gegenstand der Erfindung wird im nachstehenden anhand der Zeichnung naher erläutert.The subject matter of the invention is explained below with reference to the drawing explained in more detail.

Es zeigen: Fig. 1 die Seitenansicht eines Elektrowerkzeugs bei abgenommener Schalenhälfte, Fig. 2 die Ansicht eine mit der Steckeinheit ausgerüsteten Elektrowerkzeug längs des Schnittes A-B.They show: FIG. 1 the side view of a power tool with the removed Shell half, Fig. 2 is a view of a power tool equipped with the plug-in unit along section A-B.

Wie die Fien 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 zagehorigem Elektronikbaustein, die Eohlebürsten 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 Fien show, there is a central, plug-in connection 1 having power distribution rail 2, for example, the following components Conductively connected: a switch 3, a capacitor 4, a potentiometer 5 with corresponding Electronic component, the Eohlebürsten 6 and a plug connection 7 for the stator winding 8 of the drive motor 9. The conductive connection or contact is the individual components with the power distribution rail 2 realized in that the individual components are attached to this rail.

Um die als steckfahige Fahnen ausgebildeten Anschlußleitungen der Bürsten 6 und der Statorwicklung 8 auf einfache-Weise mit der Stromverteilerschiene 2 vereinigen zu können, ist die letztere beim Ausführungsbeispiel abgewinkelt ausgebildet worden.To the connector lines designed as pluggable flags of the Brushes 6 and the stator winding 8 in a simple manner with the power distribution rail 2, the latter is angled in the embodiment been.

Es ist ohne weiteres ersichtlich, daß eine auf diese Weise verwirklichte Innenverschaltung von Elektrowerkzeugen und gegebenenfall3 auch von anderen elektrischen Geräten auch sehr reparaturfreundlich ist, da defekte Bauelemente schnell und sicher austauschbar sind, Dies gilt insbesondere auch dann, wenn die Stromverteilungsschiene 2 durch eine gedruckte Schaltung verkörpert ist.It can be readily seen that one was accomplished in this way Internal wiring of power tools and, if necessary3, of other electrical ones Devices is also very easy to repair, as defective components are quick and safe are interchangeable, this is especially true when the power distribution rail 2 is embodied by a printed circuit.
