Stator of rotating electrical machine having signal line holding portions

摘要

A stator of a rotating electrical machine is provided. The stator includes a core unit which includes plural core assemblies arranged annularly, each core assembly being wound with a coil, plural accommodating portions which are provided to correspond to the core assemblies, each accommodating portion accommodating at least one of (i) a connection portion of end portions of adjacent coils for forming a neutral point and (ii) a connection portion of the other end portion of one of the adjacent coils and a power supply line, a temperature detector which detects at least one of a temperature of an oil and a temperature of a coil of the plural coils, and a signal line which is connected to the temperature detector for transmitting a detection signal from the temperature detector to an outside. Each of the accommodating portions includes a holding portion which holds the signal line.

1. A stator of a rotating electrical machine provided in a housing, the stator comprising:
a core unit which includes a plurality of core assemblies arranged annularly, each core assembly being wound with a coil; a plurality of accommodating portions which are provided to correspond to the core assemblies, each accommodating portion accommodating at least one of (i) a connection portion of end portions of adjacent coils for forming a neutral point and (ii) a connection portion of the other end portion of one of the adjacent coils and a power supply line; a temperature detector which detects at least one of a temperature of an oil stored in the housing and a temperature of a coil of the plurality of coils; and a signal line which is connected to the temperature detector for transmitting a detection signal from the temperature detector to an outside, wherein each of the accommodating portions includes a holding portion which holds the signal line, wherein the stator has an annular shape, wherein each of the holding portions is formed at one end portion of a corresponding accommodating portion in a rotation axis direction and pinches the signal line in a radial direction of the stator, wherein each of the holding portions includes a pair of snap pieces opposing each other and having flexibility, and wherein one of the snap pieces is longer than the other of the snap pieces in a circumferential direction of the stator.
