  • Patent number: 6280265
    Abstract: A longitudinally-extending bore connector has apertures which receive annular spring electrical connectors. To connect end turns to the bore connector, a main terminal having a prefabricated and preassembled gooseneck at its radially outer end is inserted in a radial bore to locate its distal end in the first aperture of the bore connector forming an electrical connection. The gooseneck at the radially outer end of the main terminal comprises preassembled leaves connected to the main terminal prior to assembly in the machine and connected to the end turn upon installation. A nut on the main terminal is threaded down to secure the main terminal to the shaft. A stud is similarly inserted into a second aperture of the connector bore and electrically connected thereto and to an exciter/slip ring assembly.

  • Patent number: 6020670
    Abstract: 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.degree. bend. By limiting the deflection of the main lead connector, stresses introduced into the main lead connector at the 180.degree. bend, a 90.degree. 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.
