Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
193 words
In a polyphase AC generator having at least two phasewindings, in combination, a plurality of diode means for rectifying the generator output, each diode means comprising first and second electrodes, at least two of said diode means being connected together by said first electrodes thereof, and said second electrodes thereof being secured to the respective ones of said windings so a to be connected with the same; a plurality of bus bar means fixedly connected to respective ones of said phase-windings and to the corresponding one of said second electrodes, whereby said diode means and said bus bar means form an assembly unit; electrically insulating carrier means in which said bus bar means are embedded, said carrier means Being a plate with openings into which said bus bar means extend, said openings being aligned with at least one electrode of a respective one of said plurality of diode means and the respective electrodes of said phase-windings whereby the corresponding electrode projects into the respective opening and is connected to the corresponding one of said bus bar means; and electrical conductive means in said openings for conductively joining the respective electrodes in said openings.
Claim 2
Dependent Claim
193 words
In a polyphase AC generator having at least two phasewindings, in combination, a plurality of diode means for rectifying the generator output, each diode means comprising first and second electrodes, at least two of said diode means being connected together by said first electrodes thereof, and said second electrodes thereof being secured to the respective ones of said windings so a to be connected with the same; a plurality of bus bar means fixedly connected to respective ones of said phase-windings and to the corresponding one of said second electrodes, whereby said diode means and said bus bar means form an assembly unit; electrically insulating carrier means in which said bus bar means are embedded, said carrier means Being a plate with openings into which said bus bar means extend, said openings being aligned with at least one electrode of a respective one of said plurality of diode means and the respective electrodes of said phase-windings whereby the corresponding electrode projects into the respective opening and is connected to the corresponding one of said bus bar means; and electrical conductive means in said openings for conductively joining the respective electrodes in said openings.
