Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Elektrohandwerkzeug nach der Gattung des Hauptanspruchs. Es ist, zum Beispiel durch die DE-OS 29 28 931, schon ein solches Elekrohandwerkzeug bekannt, bei dem der Handgriff ein Gehäuse aus zwei längsgeteilten Schalen hat. Durch diese Schalenbauweise sind die innenliegenden Kabel und deren Befestigungsmittel gut zugänglich. Eine solche Schalenbauweise ist für Elektrowerkzeuge mit im Winkel zueinander stehenden Gehäuse- und Griffteilen wie z.B. bei Elektro-Handkreissägen, für den Gehäuseaufbau nicht geeignet. Deshalb sind bei bekannten Konstruktionen dieser Art in das Motorgehäuse Kanäle eingeformt, durch die Anschlußleitungen hindurchgeschoben werden können. Bei der Montage des Elektrohandwerkzeuges müssen diese Leitungen an dem Stator des Motors angeschlossen und mit dem Einfügen des Stators in das Motorgehäuse durch diese Kanäle hindurchgefädelt werden.The invention relates to an electric hand tool according to the preamble of the main claim. Such an electric hand tool is already known, for example from DE-OS 29 28 931, in which the handle has a housing made of two longitudinally divided shells. This shell construction means that the internal cables and their fasteners are easily accessible. Such a shell construction is not suitable for power tools with housing parts and handle parts that are at an angle to one another, such as, for example, with electric hand-held circular saws. Therefore, in known constructions of this type, channels are formed in the motor housing, through which the connecting lines can be pushed. When installing the electric hand tool, these lines must be connected to the stator of the motor and threaded through these channels when the stator is inserted into the motor housing.

Eine solche Montage ist beschwerlich und daher aufwendig, ebenso die entsprechende Reparatur.Such an assembly is cumbersome and therefore complex, as is the corresponding repair.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Elektrowerkzeug mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß auch im Winkel zueinander verlaufende Kabelkanäle in ihrer gesamten Länge von der Seite her zugänglich sind, und daß die erforderlichen Verbindungsleitungen mit den anfügbaren Gehäuseteilen in die gebildeten Kanäle eingebracht und vorzugsweise auch kontaktiert werden können. Dies ermöglicht eine Vormontage außerhalb des Elektrowerkzeugs, bei der die Leitungsverbindungen auch durch Handhabungsautomaten vorbereitet werden können. So wird durch das Auftrennen des Gehäuses längs von Kanälen für die zu verlegenden elektrischen Verbindungsleitungen und durch das Verbinden dieser Leitungen mit den ansetzbaren, kanalbildenden Gehäuseteilen, eine Schnellmontage bzw. Reperatur an verschiedenen Stellen des Elektrowerkzeugs ermöglicht.In contrast, the power tool according to the invention with the characterizing features of the main claim has the advantage that cable channels running at an angle to one another are accessible in their entire length from the side, and that the required connecting lines with the attachable housing parts are introduced into the channels formed and preferably also contacted can be. This enables pre-assembly outside of the power tool, in which the line connections can also be prepared by automatic handling machines. Thus, by opening the housing along channels for the electrical connecting lines to be laid and by connecting these lines to the attachable, channel-forming housing parts, a quick assembly or repair at different locations of the power tool is made possible.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Elektrowerkzeugs möglich. Besonders vorteilhaft ist die Gestaltung eines anfügbaren, kanalbildenden und elektrische Leitungen tragenden Gehäuseteils mit starr mit ihm verbundenen Steckkontakten an den jeweiligen Enden der Verbindungsleitungen.The measures listed in the subclaims allow advantageous developments and improvements of the power tool specified in the main claim. It is particularly advantageous to design an attachable, channel-forming and electrical line-carrying housing part with plug contacts rigidly connected to it at the respective ends of the connecting lines.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Eine Elektro-Handkreissäge 1 besitzt ein Hauptgehäuse 2, einen längsgeteilten Handgriff 3 mit.einer gehäusefesten Schale 4 und einer abnehmbaren Schale 5 und einen Gehäusedeckel 6. Das Gesamtgehäuse wird ergänzt durch eine Kanalabdeckung 7, zwischen dem Handgriff 3 und dem Gehäusedeckel 6. Die Kanalabdeckung ist in eine Führung 11 des Hauptgehäuses 2 eingefügt und besitzt an ihrem einen Ende eine Nase 8, die von der Schalenwand 9 der Schale 5 übergriffen wird. An ihrem anderen Ende ist die Kanalabdeckung 7 mit Stufen 10 versehen, die im montierten Zustand der Elektro-Kreissäge 1 durch den Gehäusedeckel 6 übergriffen werden. Sie ist damit in jedem Fall gesichert, sowohl bei Abnahme der Schale 5 als auch des Gehäusedeckels 6. Am vom Gehäusedeckel 6 abgewendeten Ende des Hauptgehäuses 2 ist dieses mit einer Schutzhaube 12 versehen, aus der ein Kreissägeblatt 13 herausragt. Sowohl die Schutzhaube 12 als auch das Kreissägeblatt 13 sind nur in Figur 1 dargestellt. Eine Platte 14 trägt verschiedene, auch elektrische Bauelemente 15, Verbindungsleitungen 16 und Steckanschlüsse 17. Eines der Bauelemente ist ein Elektroschalter 18 mit einem Drücker 19, ein anderes ein Kondensator zur Funkentstörung,ein weiteres eine mechanische Einschaltsperre 20 für den Elektroschalter 18. Mittels Bohrungen 21 in der Platte 14 kann diese in der gehäusefesten Schale befestigt werden. Die Einbaurichtung hierzu gibt der Pfeil C an. Steckbuchsen 22 an der Platte 14 dienen dem Steckanschluß der Kanalabdeckung 7 mit entsprechenden Steckerfahnen 23. Die Steckerfahnen 23 sind über Verbindungsleitungen 24 in der Kanalabdeckung 7 angeschlossen an Steckerfahnen 25 am anderen Ende der Kanalabdeckung 7. Den Steckerfahnen 25 sind Steckbuchsen 26 einer Baugruppe 27 zugeordnet. Diese Baugruppe 27 trägt Kohlebürsten 28 in Haltern 29, welche mit zwei der vier Kontaktstecker 31 versehen sind. Die Steckbuchsen 26 sind über nicht sichtbare Leiter 30 mit den beiden anderen Steckern 31 verbunden. Kontaktstecker der Baugruppe 27 werden in Buchsen 32 am Motor 33 eingeführt, wobei die Baugruppe 27 mittels Führungsleisten am Hauptgehäuse 2 ausgerichtet und zentriert wird. Durch Anstecken der Baugruppe 27 an das Hauptgehäuse 2 werden die Kohlebürsten 28 betriebsgerecht zu den aus dem Hauptgehäuse 2 herausragenden Teilen eines Elektromotors 33 zugeordnet. Der elektrische Anschluß des Motors 33 an die durch den Handgriff 3 eingeführte Versorgungsleitung 34 erfolgt durch den gleichzeitigen Kontakt zwischen den Steckerfahnen 23 und 25 und den Steckbuchsen 22 und 26. Selbstverständlich muß zuvor oder zugleich mit dem Aufstecken der Baugruppe 27 auf das Hauptgehäuse 2 die Kanalabdeckung 7 in ihre Zusammenbaulage zum Hauptgehäuse 2 gebracht sein. Schließlich wird der Gehäusedeckel 6 aufgesetzt und sichert über die Stufen 10 die Kanalabdeckung 7 ebenso am Hauptgehäuse 2 wie die Baugruppe 27. Die Halterung des Gehäusedeckels 6 am Hauptgehäuse 2 kann in bekannter Weise mittels Schrauben oder durch Schnappverbindungen erfolgen und ist hier nicht näher dargestellt. Die Zusammensteckbewegung der vorstehend im einzelnen beschriebenen Bauelemente ist symbolisiert durch weitere Pfeile D.An electric circular saw 1 has a main housing 2, a longitudinally divided handle 3 with a shell 4 fixed to the housing and a removable shell 5 and a housing cover 6. The overall housing is supplemented by a duct cover 7, between the handle 3 and the housing cover 6. The duct cover is inserted into a guide 11 of the main housing 2 and has at one end a nose 8 which is overlapped by the shell wall 9 of the shell 5. At its other end, the duct cover 7 is provided with steps 10, which are overlapped by the housing cover 6 in the assembled state of the electric circular saw 1. It is thus secured in every case, both when the shell 5 and the housing cover 6 are removed. At the end of the main housing 2 facing away from the housing cover 6, the latter is provided with a protective hood 12 from which a circular saw blade 13 protrudes. Both the protective hood 12 and the circular saw blade 13 are only shown in FIG. 1. A plate 14 carries different ones, too Electrical components 15, connecting lines 16 and plug connections 17. One of the components is an electrical switch 18 with a push button 19, another is a capacitor for radio interference suppression, and another is a mechanical switch-on lock 20 for the electrical switch 18. By means of holes 21 in the plate 14, this can be in the shell fixed to the housing. The direction of installation indicates the arrow C. Sockets 22 on the plate 14 serve for the plug connection of the channel cover 7 with corresponding connector lugs 23. The connector lugs 23 are connected via connecting lines 24 in the channel cover 7 to connector lugs 25 at the other end of the channel cover 7. The connector lugs 25 are assigned to sockets 26 of a module 27. This assembly 27 carries carbon brushes 28 in holders 29 which are provided with two of the four contact plugs 31. The sockets 26 are connected to the other two plugs 31 via conductors 30 (not visible). Contact plugs of assembly 27 are inserted into sockets 32 on motor 33, assembly 27 being aligned and centered on main housing 2 by means of guide strips. By connecting the assembly 27 to the main housing 2, the carbon brushes 28 are assigned to the parts of an electric motor 33 protruding from the main housing 2 in a manner suitable for operation. The electrical connection of the motor 33 to the supply line 34 introduced by the handle 3 takes place through the simultaneous contact between the connector lugs 23 and 25 and the sockets 22 and 26. Of course, the duct cover must be fitted beforehand or at the same time as the module 27 is plugged onto the main housing 2 7 be brought into their assembled position to the main housing 2. Finally, the housing cover 6 is placed on and secures the channel cover 7 on the main via the steps 10 Housing 2 as the assembly 27. The mounting of the housing cover 6 on the main housing 2 can be done in a known manner by means of screws or by snap connections and is not shown here. The mating movement of the components described in detail above is symbolized by further arrows D.

Für einen eventuell notwendigen Bürstenhalteraustausch braucht lediglich der Gehäusedeckel 6 abgezogen und die Baugruppe 27 aus ihrer Steckverbindung mit dem Hauptgehäuse 2 entfernt zu werden. Ebenso rasch wie diese Demontage erfolgt die wiederholte Montage des Austauschteiles. Es sind lediglich Abzieh- bzw. Aufsteckbewegungen erforderlich. Falsches Anschließen der elektrischen Bauelemente ist ausgeschlossen. Bei Fehlern im Bereich des Elektroschalters 18 wird lediglich die Schale 5 abgezogen. Danach können defekte Bauelemente auf der Platte 14 im Innern der Schalen 4 und 5 durch die dort angeordneten Steckverbindungen auf einfache Art ersetzt werden. Dies trifft, außer für die elektrischen Bauelemente, auch für die mechanischen Teile der Einschaltsperre 20 zu. Sie können leicht von ihren Lagerachsen abgezogen werden. Auch hier ist der Zusammenbau ebenso einfach wie die Demontage. Schäden an den Verbindungsleitungen 24 in der Kanalabdeckung 7 kommen praktisch nicht vor. Sollte dennoch einmal eine Inspektion dieser Verbindungsleitungen erforderlich werden, so ist die Kanalabdeckung 7 nach dem Abziehen des Gehäusedeckels 6, der Baugruppe 27 und der Schale 5 ebenfalls abzuziehen, wobei die Steckerfahnen 23 aus den Steckbuchsen 22 herausgezogen werden.For a possibly necessary brush holder replacement, the housing cover 6 only needs to be removed and the assembly 27 removed from its plug connection with the main housing 2. Repeated assembly of the replacement part takes place just as quickly as this disassembly. Only pulling or plugging movements are required. Incorrect connection of the electrical components is impossible. In the event of faults in the area of the electrical switch 18, only the shell 5 is pulled off. Defective components on the plate 14 inside the shells 4 and 5 can then be replaced in a simple manner by the plug connections arranged there. In addition to the electrical components, this also applies to the mechanical parts of the lock 20. They can easily be pulled off their bearing axles. Here, too, assembly is just as easy as disassembly. There is practically no damage to the connecting lines 24 in the duct cover 7. Should an inspection of these connecting lines nevertheless become necessary, the duct cover 7 must also be removed after the housing cover 6, the assembly 27 and the shell 5 have been removed, the connector lugs 23 being pulled out of the sockets 22.

Im Ausführungsbeispiel nach den Figuren 4 und 5 sind die starren Steckerfahnen 23 und 25, die Steckbuchsen 22 und 26 sowie die in die Bauteile integrierten Leiter 16 (mit Steckanschlüssen 17) und 24 durch flexible Leitungen 35 mit entsprechenden Anschlußsteckern 36 ersetzt. Diese Leitungen 35 werden einerseits mittels der Stecker 36 im Schalter 18 und andererseits direkt in die Steckbuchsen 32 am Polschuh des Elektromotors 33 eingesteckt. Die Baugruppe 27 trägt dann nur 2 Kontaktstecker 31 von den Bürstenhaltern 29. Die Leitungen 35 verlaufen in den Kanälen zwischen der Platte 14 und der gehäusefesten Handgriffschale 4, sowie zwischen der Kanalabdeckung 7 und dem Motorgehäuse 2, und sind so gegen Beschädigung durch Einklemmen geschützt. Dies ist eine Alternative, die eine weniger genaue Abstimmung zwischen den mechanischen Pass- und Rastmitteln und den elektrischen Kontaktverbindungen erfordert, aber doch sehr einfach zu montieren ist.In the exemplary embodiment according to FIGS. 4 and 5, the rigid connector lugs 23 and 25, the sockets 22 and 26 and the conductors 16 (with plug connections 17) and 24 integrated into the components are replaced by flexible lines 35 with corresponding connection plugs 36. These lines 35 are inserted on the one hand by means of the plug 36 in the switch 18 and on the other hand directly into the sockets 32 on the pole piece of the electric motor 33. The assembly 27 then carries only 2 contact plugs 31 from the brush holders 29. The lines 35 run in the channels between the plate 14 and the handle shell 4 fixed to the housing, and between the channel cover 7 and the motor housing 2, and are thus protected against damage by being pinched. This is an alternative that requires less precise coordination between the mechanical fitting and locking means and the electrical contact connections, but is still very easy to assemble.
