An electrical connection for connecting the interior of an alternating current generator to the exterior of the generator. The generator has a three phase full-wave bridge rectifier that has three AC input terminal studs. The ends of three power supply conductors are connected to the terminal studs by terminals. The conductors extend from the terminal studs to the exterior of the generator and they extend through an opening formed in a side wall of the frame. The conductors are supported and guided by a conductor support part that is formed of plastic material. This conductor support part has a clamping block portion and a U-shaped conductor support portion. Portions of the conductors are disposed between a clamping block and the clamping block portion of the conductor support part. A plurality of threaded fasteners extend through aligned openings in the clamping block and in the block portion and are threaded into threaded bores formed in a lug portion of the end frame. When the fasteners are fully tightened, the conductors are tightly clamped between the clamping block and the block portion.
In combination, an alternating current generator having an end frame and a polyphase output winding, an opening in said end frame that extends entirely therethrough, a bridge rectifier having AC input terminals connected to said output winding, a plurality of electrical conductors extending from the interior of said end frame to the exterior thereof for feeding alternating current to an electrical load that is located outside of said generator, said conductors extending through said opening in said end frame, each said conductor having a terminal that is connected to a respective said AC input terminal of said bridge rectifier, a conductor support formed of plastic material secured to end frame, said conductor support extending from said opening in said end frame to said bridge rectifier and rib means on said conductor support engaging said electrical conductors to secure said conductors to said conductor support.
In combination, an alternating current generator having an end frame and a three phase output winding, said end frame having a side wall, a radially extending opening in said side wall that extends entirely therethrough, a three phase full-wave bridge rectifier in said end frame having AC input terminals, means connecting said output winding to said AC input terminals of said bridge rectifier, a conductor support formed of plastic material having a block portion and a conductor support portion extending from said block portion, said block portion located outside of said side wall of said end frame, said conductor support portion extending from said block portion to said bridge rectifier, a portion of said conductor support portion located in said radially extending opening in said side wall, fastener means for securing said block portion to said end frame, first, second and third conductors extending from the interior of said end frame to the exterior thereof, each of said conductors having a portion thereof that extends through said radially extending opening in said side wall, each of said conductors being connected to a terminal that is secured to a respective AC input terminal of said bridge rectifier, said first and second conductors extending coextensively with said conductor support portion, and means on said conductor support portion engaging said first and second conductors for securing said first and second conductors to said conductor support portion.
In combination, an alternating current generator having an end frame and a three phase output winding, said end frame having a side wall, a radially extending opening in said side wall that extends entirely therethrough, a three phase full-wave bridge rectifier in said end frame having AC input terminals, means connecting said output winding to said AC input terminals of said bridge rectifier, a conductor support formed of plastic material having a block portion and a conductor support portion extending from said block portion, said block portion located outside of said side wall of said end frame and having a plurality of openings extending therethrough, said conductor support portion extending from said block portion to said bridge rectifier, a portion of said conductor support portion located in said radially extending opening in said side wall, first, second and third conductors extending from the interior of said end frame to the exterior thereof, each of said conductors having a portion thereof that extends through said radially extending opening in said side wall, each of said conductors being connected to a terminal that is secured to a respective AC input terminal of said bridge rectifier, said first and second conductors extending coextensively with said conductor support portion, means on said conductor support portion engaging said first and second conductors for securing said first and second conductors to said conductor support portion, a clamping block formed of plastic material, said clamping block having a plurality of openings extending therethrough, said first, second and third conductors each having an axially extending portion located between said clamping block and said block portion of said conductor support, said openings in said block portion and in said clamping block being aligned with each other and with threaded bores formed in said end frame, and a threaded fastener extending through the openings in said clamping block and the openings in said block portion, said threaded fasteners being threaded into said threaded bores, said threaded fasteners causing axially extending portions of said conductors to be tightly clamped between said clamping block and said block portion.
