In a portable electric tool with a housing, a driving electric motor with a stator and rotor, together, if required, with a handle, and with circuit arrangements arranged therein, it is proposed that all the elements, leads and components relating to the electrical circuit area in each case be assembled into individual functional groups and that these be designed as building blocks (1,3,7,9,11) which can be plugged into one another, all the electrical connecting leads being laid, avoiding printed circuits or suchlike (having such leads), as metallic flat strips (21',21'',21''') from outside in guide slots (32) in the building blocks, which represent plastic partial housings. A central, main building block (7) with a U-shape, holds the bearing (31) of the rotor facing it, and mechanically fixes the stator, via pins (12), while simultaneously making contact with corresponding field-coil flat plug-in sockets (15) and, together with further flat connectors (14a,20) projecting downwards in the region of the handle, produces the required electrical contact connections to building blocks forming the remaining functional groups, such as the LEFT-RIGHT switch (9), the ON-OFF switch (1) with speed thrustors and the suppressor element (3). Oppositely located means of latching with the housing shells secure the position of the link contact part, as the main building block. <IMAGE> |
