Abstract
Description
図1乃至図5はそれぞれ、本発明の実施形態に係る電動モータの駆動制御装置を示している。図1はコネクタブロックの背面の平面図、図2はコネクタブロックを背面側から見た斜視図、図3はコネクタブロックの背面にプリント回路基板を実装する工程について説明するための斜視図である。また、図4は電動モータの駆動制御装置の外観斜視図、図5は図4に示した駆動制御装置の分解斜視図である。
この電動モータの駆動制御装置は、例えば車両の電動ステアリング装置に適用するもので、操舵力を発生あるいはアシストする電動モータの駆動制御に用いられる。
外装部材1と外装部材6はペアをなしており、図示しないシール材を介して接合される。外装部材1の一方の面からモータ軸とこのモータ軸に取り付けられたギヤ2aが突出しており、外装部材6の対向面には開口6aが形成され、コネクタブロック5の正面5a側に設けられた接続間口5cが突出している。
障壁部15-2と窪み部14-3、障壁部15-3と窪み部14-4はそれぞれ、CAN通信端子13-1,13-2に塗布されて流出した過剰フラックスを貯留する貯留部を形成する。
上記塗布工程においては、図7に示すように、コネクタブロック5の背面5bの外周部に沿ったガート壁18を設けても良い。ガート壁18を設けてスプレーノズル17からフラックス剤22を噴霧することで、フラックス剤22の飛散を低減できる。
同様に、CAN通信端子13-1の部分(領域16-3)から流出した過剰フラックスは、窪み部14-3と障壁部15-2からなる貯留部に貯留される。CAN通信端子13-2の部分(領域16-4)から流出した過剰フラックスは、窪み部14-3と障壁部15-3からなる貯留部に貯留される。
なお、肉盛り部19の上面19aに、傾斜面や丸みを形成することで、フラックスの滞留量を更に抑制できる。
上述したように、貯留部には様々な変形が考えられ、過剰フラックスを貯留できる。
これによって、フラックス残渣によるマイグレーションの発生やシール部の硬化阻害を抑えて高品質な製品の安定的供給が可能となる。また、フラックス残渣の目視による確認作業や、手作業による拭き取り作業を低減できることで製造コストを低減できる。
