ELECTRICAL CONDUCTORS WITH A LONGITUDINAL GROOVE AND SLOTS PERPENDICULAR THERETO

摘要

The invention concerns an electrical conductor (1) which can be stacked with a plurality of identical conductors (1), at least one insulating layer (13) being inserted between every two adjacent conductors (1). The electrical conductor (1) is bounded by two substantially plane main sides (4, 5) perpendicular to the stacking direction (3) and has at least a plurality of slots (6) arranged one behind the other each of which passes through the conductor (1) in approximately the stacking direction (3). A longitudinal groove (8) associated with the plurality of slots is located on at least one main side (4). The floor (10) of the groove is approximately perpendicular to the stacking direction (3) and depth of the groove, measured in the stacking direction (3), is small compared with the maximum thickness of the conductor (1). The opening (7) of each slot (6) is located in this main side (4) in the floor of the longitudinal groove (10) and at a distance from each wall (9) of the longitudinal groove (8). The electrical conductor (1) can be made simply and cheaply and no expensive subsequent machining is required to remove burrs and/or to ensure sufficiently large leakage paths between pairs of adjacent conductors (1).
