In-vehicle structure for inverter and bracket unit for inverter
An in-vehicle structure for an inverter includes a bracket, a damping bush, and a braided wire. The bracket is made of a metal plate, and serves as a metal fitting for fixing the inverter to a transmission (a vehicle). The damping bush is fitted between the bracket and either one of a case of the inverter and the transmission. The damping bush is made of an insulator. The braided wire electrically connects the case of the inverter to the transmission. The braided wire is wired along the metal plate of the bracket.
1. An in-vehicle structure for an inverter configured to supply electric power to a drive motor, the in-vehicle structure comprising:
a bracket being a metal plate, the bracket being configured to fix the inverter to a vehicle;
a damping bush being an insulator, the damping bush being fitted between the bracket and one of a case of the inverter and the vehicle; and
a braided wire configured to electrically connect the case of the inverter to a body of the vehicle, the braided wire being wired along the metal plate of the bracket.
2. The in-vehicle structure according to claim 1 , wherein:
the damping bush is attached between the bracket and the case;
one end of the braided wire is electrically connected to the case; and
the other end of the braided wire is electrically and mechanically connected to the bracket.
3. The in-vehicle structure according to claim 1 , wherein:
the damping bush includes a bush main body and a metal fitting, the bush main body being an insulator, and the bush main body being attached to an end part of the bracket, the metal fitting being joined to the end part of the bracket via the bush main body, and the metal fitting making contact with the case; and
one end of the braided wire is electrically and mechanically connected to the metal fitting.
4. The in-vehicle structure according to claim 1 , wherein
the braided wire is flat, and a flat surface of the braided wire faces the metal plate of the bracket.
5. A bracket unit for fixing an inverter to a vehicle, the inverter configured to supply electric power to a drive motor, the bracket unit comprising:
a first fixing portion made of metal, the first fixing portion being fixed to one of a case of the inverter and the vehicle;
a second fixing portion made of metal, the second fixing portion being fixed to the other one of the case and the vehicle;
a connection portion being a metal plate, the connection portion being configured to connect the first fixing portion to the second fixing portion;
a bush main body made of an insulator, the bush main body being attached to the first fixing portion;
a metal fitting joined to the first fixing portion via the bush main body; and
a braided wire configured such that one end of the braided wire is electrically and mechanically connected to any one of the first fixing portion, the second fixing portion, and the connection portion, the braided wire being configured such that the other end of the braided wire is electrically and mechanically connected to the metal fitting, and the braided wire being wired along the connection portion.
