Abstract
A connection arrangement for coupling a brush bearing sub-assembly to the stator field windings in an electric motor. The sub-assembly has a plate with a plurality of terminal blades extending perpendicularly, the blades being arranged in staggered pairs of one long blade and one short blade. The stator has corresponding pairs of connectors, staggered in accordance with the staggered terminal blades of the sub-assembly, with each connector including a resilient, omega-shaped conductive element. The corresponding staggered arrangement of the terminal blades and stator connectors provides for accurate coupling of the two, since the shape of the resilient connectors permits insertion from either a lateral or axial direction.
