Rotary electric machine

摘要

A rotary electric machine includes a stator around which coil conductor wires for a plurality of phases are wound, a housing that contains the stator, and a terminal block that is mounted on the housing and connects end portions of the coil conductor wires for the respective phases led from the stator to corresponding external power supply lines. A coolant is supplied to the stator in the housing. The terminal block includes: a plurality of relay conductors, each relay conductor having one end connected to an external power supply line and the other end connected to an end portion of the coil conductor wires for 10 the respective phases, and a terminal block body that is made of an insulating material and holds the plurality of relay conductors.

1. A rotary electric machine comprising:
a stator around which coil conductor wires for a plurality of phases are wound; a housing that contains the stator; and a terminal block that is mounted on the housing and connects end portions of the coil conductor wires for the respective phases led from the stator to corresponding external power supply lines, wherein a coolant is supplied to the stator in the housing, the terminal block includes: a plurality of relay conductors, each relay conductor having one end connected to an external power supply line and an other end connected to an end portion of the coil conductor wires for the respective phases, and a terminal block body that is made of an insulating material and holds the plurality of relay conductors, and the terminal block body includes: a base wall on which connection portions between the respective relay conductors and the end portions of the corresponding coil conductor wires are disposed so as to be separated from each other; an outer wall that is disposed between an inner wall of the housing and the connection portions disposed on the base wall so as to be along an end edge of the base wall; a plurality of partition walls that extend from the outer wall or the base wall and insulate peripheral portions of the connection portions together with the outer wall; a connection space portion that is surrounded by the base wall, the outer wall, and the plurality of partition walls and contains the connection portions; and slit through which the connection space portion communicates with the inner wall of the housing.
