Bei einer bekannten Handwerkzeugmaschine sind die elektrischen Bauelemente durch innerhalb des Gehäuses der Handwerkzeugmaschine verlegte Kabel bzw. Litzen miteinander verbunden. Der Anschluß der Leiter an die Bauelemente erfolgt entweder mittels bekannter Lüsterklemmen oder durch Verlöten in dazu vorgesehenen Lötfahnen. Es ist auch schon vorgeschlagen worden, zum elektrischen Kontaktieren von Wicklungsdrahtenden vom zum Beispiel in Spulen des Stators eines Universalmotors eingelegten Spulen die Wicklungsdrahtenden mit besonderen Anschlußdrähten zu verschweißen. Diese bekannte Art und Weise der Verbindung der elektrischen Bauelemente führt an sich zu zufriedenstellenden Ergebnissen. Allein hat sie den Nachteil, daß sie kostenintensiv ist, weil viele Arbeitsgänge manuell ausgeführt werden müssen. Ein weiterer Nachteil ist, daß die Anschlußdrähte bei der Montage unter Umständen vertauscht werden können.In a known handheld power tool, the electrical components are through within the housing of the handheld power tool laid cables or strands connected to one another. The connection of the conductors to the components takes place either by means of known luster terminals or by soldering in solder lugs provided for this purpose. It has also been suggested for electrical contacting of winding wire ends from, for example, inserted into the coils of the stator of a universal motor Coils to weld the winding wire ends with special connecting wires. This known way of connection of the electrical components leads to satisfactory results. But it has the disadvantage that it is costly because many operations have to be carried out manually. Another disadvantage is that the connecting wires can possibly be mixed up during assembly.
Die erfindungsgemäße elektrische Maschine mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Leitungsführung zwischen den einzelnen elektrischen Bauelementen stark vereinfacht ist. Die Leitungsführung ist sicher, Störungen durch Leitungsunterbrechungen werden weitgehend vermieden. Außerdem wird hierdurch die automatisierte Montage der eleketrischen Maschine sehr vereinfacht, da die die Enden der Leiterbahnen bildenden Kontaktierungselemente immer an genau der gleichen Stelle liegen. Die elektrischen Bauelemente können durch einfaches Einlegen in das Gehäuse miteinander elektrisch verbunden werden.The electrical machine according to the invention with the characteristic Features of the main claim has the advantage that the wiring between the individual electrical Components is greatly simplified. The line management is safe, disruptions caused by line interruptions are largely avoided. It also makes the automated Assembly of the electrical machine is very simplified, since the contacting elements forming the ends of the conductor tracks always lie in exactly the same place. The electrical components can be easily inserted into the housing are electrically connected to each other.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenenen elektrischen Maschine möglich. Besonders vorteilhaft ist, daß die Leiterbahnen auf die Wandbereiche aufgedampft, gespritzt oder galvanisch aufgebracht sind. Als sehr zweckmäßig hat sich auch erwiesen, daß die Kontaktierungselemente einstückig mit den Leiterbahnen verbunden sind und in die Wandbereiche ebenfalls mit eingeformt sind.The measures listed in the subclaims are advantageous developments and improvements of the main claim specified electrical machine possible. It is particularly advantageous that the conductor tracks on the wall areas vapor-deposited, sprayed or galvanically applied. as It has also proven very useful that the contacting elements are integrally connected to the conductor tracks and are also molded into the wall areas.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 eine Handwerkzeugmaschine im Längsschnitt und Figur 2 einen halbschematischen Schnitt längs II-II der Figur 1.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a hand machine tool in longitudinal section and FIG. 2 shows a semi-schematic section along II-II of Figure 1.
In den Figuren 1 und 2 ist eine Handwerkzeugmaschine dargestellt, in deren Gehäuse 1 ein Universalmotor 2 angeordnet ist. Der Universalmotor 2 hat einen geblechten Stator 3, in den Spulen eingelegt sind, von denen in Figur 1 nur die aus dem Blechpaket des Stators 3 hervorragenden Wickelköpfe 4 sichtbar sind. Konzentrisch ist im Innern des Stators 3 eine Motorwelle 5 angeordnet, die in Wälzlagern gelagert ist, von denen in der Zeichnung ein Kugellager 6 dargestellt ist. Die Motorwelle 5 trägt einen im Innern des Stators 3 liegenden, in der Zeichnung nicht sichtbaren Rotor und einen Kollektor 7j gegen den in bekannter Weise Schleifbürsten 8, die in Bürstenhalter 9 geführt sind, gehalten werden. Jedem Bürstenhalter 9 ist eine in die StromzufüWPungsleitung eingeschaltete Dros-In FIGS. 1 and 2, a handheld power tool is shown, in the housing 1 of which a universal motor 2 is arranged. The universal motor 2 has a laminated stator 3, in the coils are inserted, of which in Figure 1 only from the Laminated core of the stator 3 outstanding winding heads 4 are visible. A motor shaft is concentric in the interior of the stator 3 5 arranged, which is mounted in roller bearings, of which a ball bearing 6 is shown in the drawing. The motor shaft 5 carries a rotor, not visible in the drawing, located inside the stator 3, and a collector 7j against the in a known manner grinding brushes 8, which are in brush holder 9 are held. Each brush holder 9 is connected to the power supply line

Im Handgriff der als Bohrmaschine ausgeschalteten Handwerkzeugmaschine ist ein die Stromzufuhr zum Universalmotor steuernder Schalter 11 angeordnet.In the handle of the hand tool that is switched off as a drill a switch 11 controlling the power supply to the universal motor is arranged.
Die elektrische Verbindung zwischen den erwähnten elektrischen Bauteilen der Handwerkzeugmaschine - in den Stator 3 eingelegte Spulen, Bürstenhalter 9 mit Drossel 10 und Schalter 11 ist mittels in Wandbereiche 12 des Gehäuses 1 der Handwerkzeugmaschine eingeformter Leiterbahnen 13 bewerkstelligt. Die Leiterbahnen 13 sind als Stromschienen ausgestaltet, die in die Wandbereiche 12 - Querwand im Gehäuse 1 der Handwerkzeugmaschine - eingespritzt sind. An ihren Enden sini die Leiterbahnen 13 einstückig mit als Kontaktstifte Ik ausgestalteten Kontaktierungselementen verbunden. Die Kontaktstifte Ik stehen - wie besonders gut in Figur 1 zu erkennen ist - im rechten Winkel aus den die Leiterbahnen 13 aufnehmenden Wandbereichen 12 hervor. Auf die Kontaktstifte I^ sind Kontaktbuchsen 15 der zu verbindenden elektrischen Bauelemente aufgeschoben. Zugeordnete Kontaktbuchsen 15 sind einerseits in einem zugeordneten Gehäusefortsatz 16 des Schalters 11 (Figur 2) angeordnet. An der dem Kollektor 7 zugewandten Stirnseite des Blechpakets des Stators 3 sind Haltemittel 17 angeordnet, die ebenfalls Kontaktbuchsen 15 tragen, welche mit den Wicklungsdrahtenden der in den Stator 3 eingelegten Spulen verbunden sind. Auch in diese Kontaktbuchsen 15 sind zugeordnete Kontaktstifte Ik eingeschoben (Figur 1). Auch die Drosseln 10 stehen mit ihren den Bürstenhaltern 9 abgewandten Enden mit ihr als Berührungskontakten wirkenden Kontaktstiften lh in Verbindung.The electrical connection between the aforementioned electrical components of the handheld power tool - coils inserted into the stator 3, brush holder 9 with choke 10 and switch 11 is established by means of conductor tracks 13 molded into wall areas 12 of housing 1 of the handheld power tool. The conductor tracks 13 are designed as busbars which are injected into the wall areas 12 - transverse wall in the housing 1 of the handheld power tool. At their ends, the conductor tracks 13 are integrally connected to contacting elements configured as contact pins Ik. As can be seen particularly well in FIG. 1, the contact pins Ik protrude at right angles from the wall areas 12 receiving the conductor tracks 13. Contact sockets 15 of the electrical components to be connected are pushed onto the contact pins I ^. Associated contact sockets 15 are arranged on the one hand in an associated housing extension 16 of the switch 11 (FIG. 2). On the end face of the laminated core of the stator 3 facing the collector 7, holding means 17 are arranged which also carry contact sockets 15 which are connected to the winding wire ends of the coils inserted in the stator 3. Associated contact pins Ik are also inserted into these contact sockets 15 (FIG. 1). The throttles 10 are also connected with their ends facing away from the brush holders 9 with contact pins lh acting as touch contacts.
