  • Patent number: 9893584
    Abstract: An end winding support for an electric generator includes a pair of winding lead supports formed on opposite sides of a winding slot and separated by an upper slot width. Each of the winding lead supports includes a winding channel routed between a lead coupling port and the winding slot. The winding slot includes a base support and a pair of alignment members that define a transition between the base support and the winding lead supports. A lower slot width is defined along the base support between the alignment members and a ratio of the upper slot width to the lower slot width is between 1.024 and 1.053.

  • Publication number: 20060040536
    Abstract: A lever type electrical connector assembly includes a first connector. A mating assist lever is pivotally movably mounted on the first connector. A slide member is linearly movably mounted on the first connector. A first cam groove and cam follower mechanism is provided between the mating assist lever and the slide member, whereby pivotal movement of the lever relative to the first connector effects linear movement of the slide member relative to the first connector. A second connector is provided with a second cam groove and cam follower mechanism between the slide member and the second connector, whereby the connectors are mated and unmated in response to rotation of the mating assist lever and resulting translation of the slide member. A latch member is provided on the slide member and is latchingly engageable with the first connector and releasable by the second connector, whereby the slide member and the mating assist lever cannot move unless the connectors are at least preliminarily mated.
