Abstract: The connector, for example, is in the form of a terminal portion of a commutator segment and has two overlying parts. Each part is provided with a slot open at one end and the two slots are arranged so as to be only partly in register with one another so that the resulting slot in the terminal portion is narrower than each of the slots in the two overlying parts and is open at one end for receiving and gripping an armature winding portion. Non-aligned regions (as considered in a direction perpendicular to the plane of each overlying part) bordering the slots of the two overlying parts are offset, e.g. part sheared, out of the plane of the respective part towards the other part.
