Abstract
Description
図1、図2は、第1実施形態の回転電機の固定子構造の主要構成を示す断面図及び平面図である。第1実施形態の回転電機の固定子構造10は、モータを構成するステータ12と、ステータ12を収容する筐体22と、ステータに組み付けるバスリング32と、バスリング32に仮組みされたサーミスタユニット60(温度センサ)と、から構成される。
図7に、第1実施形態の回転電機の固定子構造の組み付け工程のフロー図を示す。図8乃至図11に、第1実施形態の回転電機の組み付け工程の模式図を示す。ステップS1(図7)において、筐体22にステータ12を組み付けるとともに、バスリング32にサーミスタユニット60を仮組みする(図8)。
第1実施形態の回転電機の固定子構造10によれば、ステータ12に組み付けられるサーミスタ62(センサ)とサーミスタ62を電気的に外部に接続するコネクタ74とを接続するリード線72が開口部30の淵と端子台44との隙間に挿通されている。これにより、筐体22に対してコネクタ74を挿通するための挿通孔を開口部30とは別に形成する必要はないので、その分、筐体22(モータ)の軸方向の小型化が可能となる。
図12に、第2実施形態の回転電機の固定子構造の模式図を示す。図12において、(A)はサーミスタユニットの仮組み時、(B)はサーミスタユニットの仮組みの解除時を表す。なお、以後の説明では、第1実施形態と共通する構成要素については同一の符号を付し、必要な場合を除いてその説明を省略する。第2実施形態は、サーミスタユニット60の組み付け位置が開口部30から遠い位置にあり、リード線72の筐体22(図1等参照)内に配置される分を長くする必要がある場合に好適できる。これにより、バスリング32の組み付け時においてリード線72が無秩序に絡まる等取り扱いが煩雑になり作業効率が低下することを防ぐ。
図13に、第3実施形態の回転電機の固定子構造の模式図を示す。第3実施形態の回転電機の固定子構造においては、収容部52及び巻き付け部54が省略され、嵌め込み部82にリード線72が嵌め込まれる。嵌め込み部82は、端子台44の幅方向の側面、または底面に取り付けられ、端子台44とともにリード線72を挟み込むようにL字型の断面形状を有している。そして、嵌め込み部82と端子台44との隙間はリード線72(後述のチューブ)の直径よりもやや狭くなるように設計されており、嵌め込み部82の開口部84から当該隙間にリード線72が嵌め込まれる。なお、ここで、嵌め込み部82は、端子台44に複数取り付けられているが、図中の矢視図に示すように、開口部84の向きを全て同じ向きすることが好適である。これにより、リード線72を開口部84の向きに引っ張るだけでリード線72を全ての嵌め込み部82から離間させることができる。このような嵌め込み部を82用いることにより、仮組み時のリード線72の不意の脱落を防止できる。
図14に、第4実施形態の回転電機の固定子構造の模式図を示す。第4実施形態の組み付け構造では、第3実施形態の構成において、コネクタ74が端子台44の下部に仮組みされた形となっている。すなわち、端子台44は、端子台44の先端部分を形成する厚肉部86と、端子台44の根元部分を形成し厚肉部86との間で厚み方向に段差を形成する薄肉部88と、薄肉部88の段差形成部分に設けられコネクタ74を仮組みする仮組み部90と、を備えている。
図15に、第5実施形態の回転電機の固定子構造の模式図を示す。第5実施形態の回転電機の固定子構造では、サーミスタホルダ64及びコネクタ74が、筐体22に仮組みされている。一方、図示は省略するが、バスリング32においては、サーミスタホルダ64、コネクタ74、リード線72を仮組みする構成を省略している。例えば、サーミスタホルダ64は、外部端子用ホルダ28に形成したダボ(不図示)にダボ孔66を嵌め込むことにより仮組みされ、コネクタ74は、コネクタ74に形成したダボ孔(不図示)を外部端子用ホルダ28に形成したダボ(不図示)に嵌め込むことにより仮組みされる。またリード線72は、開口部30に挿通しているが、外部端子用ホルダ28に巻きつけられるともに、外部端子用ホルダ28の側面(及び開口部30に対向する側面)に形成された切り欠き28bに嵌め込まれている。この切り欠き28bの幅はリード線72(後述のチューブ)の直径よりもやや小さな寸法を有している。
