Abstract

The present invention relates to a power tool, including at least a first and a second housing part, many components, in particular electric motor components or electrical components, and one fastening element for fastening the many components to the first housing part in such a way that the components are fixed between an inside of the first housing part and the fastening element.

Claims (24)

1. A power tool comprising

at least a first and a second housing part ( 13 ),

a plurality of electrical components or electric motor components and

one fastening element ( 1 ) for fastening the plurality of components to the first housing part ( 13 ) in such a way that the components are fixed between an inside of the first housing part ( 13 ) and the fastening element ( 1 ),

the fastening element having at least two bores ( 3 , 4 ) both of which are adapted to accept mounting screws, wherein the one fastening element ( 1 ) is located in a commutation region of the power tool.

2. The power tool as recited in claim 1 , wherein the first housing part ( 13 ) comprises a plurality of positioning elements ( 15 , 17 ), for positioning at least selected ones of the components before the mounting of the fastening element ( 1 ) to the first housing part ( 13 ).

3. The power tool as recited in claim 2 , wherein the positioning of the components in the positioning elements ( 15 , 17 ) is effected by means of clamping or plugging in or pressing against.

4. The power tool as recited in claim 2 , wherein the one fastening element ( 1 ) comprises a guide conduit ( 2 ) for carrying air and/or a conduit for guiding a cable.

5. The power tool as recited in claim 2 , wherein the one fastening element ( 1 ) comprises further components ( 11 ), which are located directly on the one fastening element ( 1 ).

6. The power tool as recited in claim 2 , wherein the one fastening element ( 1 ) comprises an electric contact lug and/or at least one cable hold-down device ( 8 ).

7. The power tool as recited in claim 3 , wherein the one fastening element ( 1 ) comprises further components ( 11 ), which are located directly on the one fastening element ( 1 ).

8. The power tool as recited in claim 1 , wherein the one fastening element ( 1 ) comprises a guide conduit ( 2 ) for carrying air and/or a conduit for guiding a cable.

9. The power tool as recited in claim 1 , wherein the one fastening element ( 1 ) comprises further components ( 11 ), which are located directly on the one fastening element ( 1 ).

10. The power tool as recited in claim 1 , wherein the one fastening element ( 1 ) comprises an electric contact lug and/or at least one cable hold-down device ( 8 ).

11. The power tool as recited in claim 1 , wherein the one fastening element ( 1 ) comprises a covering region ( 5 , 6 ) for covering dirt-threatened components.

12. The power tool as recited in claim 1 , wherein the one fastening element ( 1 ) is produced from plastic or a sheet-metal material.
