Zusammenfassung:To provide a connection structure between a stator temperature sensor and an external terminal in which a manual work involved when a harness wire is arranged is reduced during a stator assembling step.SOLUTION: The connection structure is between a temperature sensor for a stator of a rotary electric machine and an external terminal. The stator includes a stator main body including a stator core and three-phase coils wound around the stator core, and a neutral wire bus bar which is connected to each of the three-phase coils at the positions of coil ends projected axially outward from the stator core. The temperature sensor is disposed and fixed to the neutral wire bus bar. A temperature sensor connector is disposed on the surface of the neutral wire bus bar. A harness wire is attached to the external terminal. A harness connector is attached to an end, of the harness wire, opposite to the external terminal. The harness connector is configured to be fitted to the temperature sensor connector.SELECTED DRAWING: Figure 2 【課題】ステータの組み立て工程において、ハーネス線の取り回しに伴う手作業を削減することができる、ステータの温度センサと外部端子との接続構造を提供する。【解決手段】回転電機のステータの温度センサと外部端子との接続構造であって、前記ステータは、ステータコアと、ステータコアに巻装された三相のコイルとを含むステータ本体と、前記ステータコアより軸方向外側に張り出したコイルエンドの位置で前記三相のコイルのそれぞれに接続された中性線バスバと、を備え、前記中性線バスバには前記温度センサが固定配置され、前記中性線バスバの表面には、温度センサコネクタが配置され、前記外部端子にはハーネス線が取り付けられ、前記ハーネス線における前記外部端子とは反対側の端にはハーネスコネクタが取り付けられ、前記ハーネスコネクタは前記温度センサコネクタと嵌合するように構成されている。【選択図】図2
