A terminal portion having a connecting recess is provided on the conductive member so as to face one end in the axial direction of the stator, and the coil terminal in a state of being inserted into the inner back portion of the connecting recess is clamped by the terminal portion.

ステータが有するコイルのコイル端末が、導電部材に設けられた端子部の接続凹部の内奥部に挿入され、接続凹部の内奥部に挿入されたコイル端末が端子部の挟圧によって該端子部に電気的に接続されるようにした電動モータが、特許文献１で知られている。   The coil terminal of the coil of the stator is inserted into the inner back part of the connection concave part of the terminal part provided on the conductive member, and the coil terminal inserted into the inner back part of the connection concave part is inserted into the terminal part by the clamping pressure of the terminal part. An electric motor configured to be electrically connected to is known from Patent Document 1.

特開２００９−３３８４８号公報JP 2009-33848 A

ところが、上記特許文献１で開示されるもののように、接続凹部の内奥部に挿入されたコイル端末を、端子部で挟圧する際にコイル線材のスプリングバック作用によってコイル端末が接続凹部の内奥部から接続凹部の開口部側に戻ってしまう可能性があり、コイル端末が端子部に正規位置からずれて接続され、接続信頼性が低下してしまう虞がある。   However, like the one disclosed in Patent Document 1, when the coil terminal inserted in the inner part of the connection recess is clamped by the terminal part, the coil terminal is moved into the inner part of the connection recess by the springback action of the coil wire. May return to the opening side of the connection concave portion, and the coil terminal may be connected to the terminal portion out of the normal position, resulting in a decrease in connection reliability.

本発明は、かかる事情に鑑みてなされたものであり、コイル端末を端子部の内奥部の正規位置に確実に接続し得るようにした回転電機を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a rotating electrical machine in which a coil terminal can be reliably connected to a normal position in an inner part of a terminal part.

上記目的を達成するために、本発明は、ステータが有するコイルのコイル端末が前記ステータの軸方向一端部から延出され、前記コイル端末の非接続状態では略Ｕ字状もしくは略Ｖ字状として前記ステータの周方向一方に開口する接続凹部を有する端子部が前記ステータの軸方向一端部に対向して導電部材に設けられ、前記接続凹部の内奥部に挿入された状態にある前記コイル端末が、前記端子部で挟圧されることで該端子部に電気的に接続される回転電機において、前記コイル端末が、前記ステータの周方向で前記接続凹部の前記内奥部に関して該接続凹部の開口端とは反対側に設定される引き出し位置で、前記ステータの軸方向一端部から延出されることを特徴とする。   In order to achieve the above object, according to the present invention, a coil terminal of a coil included in a stator is extended from one axial end of the stator, and is substantially U-shaped or substantially V-shaped when the coil terminal is not connected. The coil terminal in a state in which a terminal portion having a connection concave portion opened in one circumferential direction of the stator is provided in the conductive member so as to face one end portion in the axial direction of the stator and is inserted into the inner back portion of the connection concave portion. However, in the rotating electrical machine that is electrically connected to the terminal portion by being pinched by the terminal portion, the coil terminal is connected to the inner recess of the connection recess in the circumferential direction of the stator. The pull-out position is set on the side opposite to the opening end, and is extended from one axial end of the stator.

本発明の上記構成によれば、コイル端末をステータの軸方向一端部から引き出して端子部の接続凹部の内奥部に導く際に、ステータの軸方向一端部からのコイル端末の引き出し位置からステータの周方向一方に接続凹部の内奥部が在り、その内奥部からステータの周方向一方側に接続凹部の開口端が在るので、接続凹部の内奥部と、ステータの軸方向一端部からのコイル端末の引き出し位置との間でコイル端末に張力を作用させることができ、コイル端末に接続凹部の内奥部側に向けて力を作用させることができるので、コイル端末を端子部で挟圧する際にコイル端末を接続凹部の内奥部の正規位置に確実に配置させることができ、接続信頼性を高めることができる。   According to the above configuration of the present invention, when the coil terminal is pulled out from one axial end portion of the stator and led to the inner back portion of the connection concave portion of the terminal portion, the stator is moved from the coil terminal pulling position from the axial end portion of the stator. There is an inner back portion of the connection recess on one side in the circumferential direction, and there is an opening end of the connection recess from the inner back portion to one side in the circumferential direction of the stator, so that the inner back portion of the connection recess and one axial end portion of the stator Since it is possible to apply tension to the coil terminal between the coil terminal and the position where the coil terminal is pulled out from the coil terminal, it is possible to apply force to the inner side of the connection recess on the coil terminal. When pinching, the coil terminal can be reliably arranged at the normal position in the inner back portion of the connection recess, and the connection reliability can be improved.
