  • Patent number: 10850687
    Abstract: In a vehicle-mounting structure disclosed by the present specification, a housing (20) of an electric power controller (5) is supported above an in-vehicle transaxle via a bracket having an insulative vibration-proof material. The housing (20) and the transaxle are connected to each other by power cables (19). A braided wire (17) for grounding is routed along the power cables (19). A connector (10) of the power cables (19) has a resin flange (112) on a surface thereof that is joined to the housing (20). The connector (10) is fixed to the housing (20) by bolts (12a and 13a) that penetrate the flange (112). An end fitting (16) of the braided wire (17) is attached to the flange (112). The end fitting (16) and the bolt (13a) are electrically connected to each other by a conductive plate (14a).

  • Patent number: 10847913
    Abstract: A terminal fitting (1) includes a rectangular tubular body (10). A resilient contact piece (16) is arranged inside the body (10) and a pressure receiving piece (18) faces the resilient contact piece (16) inside the body (10). The resilient contact piece (16) has a base end (16Eb) curved inward of the body (10) from an end of the body (10). The pressure receiving piece (18) has one end including a base end (18Eb) curved inwardly of the body (10) from an end of the body (10). An area of a first facing surface (16F) of the resilient contact piece (16) to be contacted by a tab (41) serves as a first plating area (16M) having Ag plating applied thereto. Areas of a second facing surface (18F) of the pressure receiving piece (18) to be contacted by the tab (41) serves as second plating areas (18M) having Ag plating applied thereto.
