Connector support block for limiting deflection of a main lead connector in an electric machine

摘要

A connector support block has a recess defined in part by an arcuate surface for limiting deflection of a main lead connector coupled between the main lead terminal and the innermost turn of end coils on a generator. The recess is spanned by a pin displaceable in elliptical openings in flanges defining the recess and about which pin the main lead connector makes a 180 DEG bend. By limiting the deflection of the main lead connector, stresses introduced into the main lead connector at the 180 DEG bend, a 90 DEG bend and the joint between the main lead connector and innermost turn are reduced under cyclic loading whereby increased fatigue life of the main lead connector is provided.
