车辆用电动压缩机及车辆用电动压缩机的制造方法
Abstract:
车辆用电动压缩机具备压缩机壳体(11)、逆变器电路(24)、逆变器壳体(21)、封闭逆变器壳体的开口部的盖(30)。另外，车辆用电动压缩机具有被夹在逆变器壳体与盖之间，将所述逆变器壳体与盖之间密封的密封部件(42、42a、42b)。另外，车辆用电动压缩机具备导电部件(41、50、33)。导电部件使逆变器电路使电流向电动马达流动时从逆变器电路向逆变器壳体传播的电磁波噪音从逆变器壳体向压缩机壳体及盖中的至少一方传递。
Abstract(English):

A vehicular electric compressor is provided with: a compressor case (11); an inverter circuit (24); an inverter case (21); and a lid (30) which closes an opening portion of the inverter case. The vehicular electric compressor also includes a seal member (42, 42a, 42b) which is sandwiched between the inverter case and the lid so as to seal a gap between the inverter case and the lid. The vehicularelectric compressor is also provided with a conductive member (41, 50, 33). The conductive member, when the inverter circuit allows a current to flow through the electric motor, transmits an electromagnetic wave noise, propagating from the inverter circuit to the inverter case, to the compressor case and/or the lid from the inverter case.
