Abstract
A method of wiring an electric device, particularly an electric tool, comprises engaging conductor wires adjacent the ends thereof in bores and/or grooves provided in plastic carrier elements, with bared ends of at least some of the conductor wires protruding from these carrier elements. Then inserting the carrier elements, with the conductor wires engaged therein, into at least part of the housing of the electric device. And, electrically connecting the conductor wires by plugging carrier elements together and/or to an electrical component of the electric device, with said protruding bared ends functioning as plug pins. Preferably, the conductor wires each have a single solid conducting core having a cross-sectional area in the range of 1 to 5 mm. Such relatively rigid wires can be pre-shaped before insertion into a housing of the electric device. The rigidity of the wires, their pre-shaping, the carrier elements and the protruding bared ends of the wires enable the wiring of the device to be carried out mechanically.
