Title:
RECTIFIER OF ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2019041579
Kind Code:
A
Abstract:
To provide a rectifier of a rotary electric machine in which a press-fitting structure (press-fitting means 300) of a rectifier cell 70 into a radiation fin (cooling plate) 72 is changed so that performance is improved, and miniaturization and cost reduction is attained while a press-fitting method is used as the fixing means of the rectifier cell 70.SOLUTION: Press-fitting means 300 that is interposed between a rectifier cell 70, 71 and mounting hole 200 of a radiation fin 72, 73 comprises: a metal insert member 310 which forms a press-fitting part P; and a release groove 320 which forms a non-press-fitting part Q. Therefore, area of the press-fitting part P can be adjusted by the non-press-fitting part Q, and press-fitting load applying to the rectifier cell 70 can be adjusted by use of deformation of the insert member 310. The insert member 310 can facilitate radiation of the rectifier cell 70. Miniaturization and cost reduction can be attained because only the insert member 310 is added.SELECTED DRAWING: Figure 2
