Electric compressor for a vehicle
An electric compressor for a vehicle includes an inverter, a motor, and a first connector and a second connector electrically connecting an in-vehicle power supply and the motor with the first connector and the second connector being fitted to each other. The first connector includes a tubular receiving portion made of resin and a first conductive portion disposed inside the receiving portion. The second connector includes a tubular insertion portion made of resin and insertable into the receiving portion, and a second conductive portion disposed inside the insertion portion and connected to the first conductive portion. A rib is disposed between an inner surface of the receiving portion and an outer surface of the insertion portion. The rib is formed integrally with one of the inner surface and the outer surface, and is in contact with the other of the inner surface and the outer surface.
1. An electric compressor for a vehicle comprising:
an inverter that converts direct current electric power supplied from an in-vehicle power supply to alternating current electric power;
a motor driven by the alternating current electric power outputted from the inverter; and
a first connector and a second connector electrically connecting the in-vehicle power supply and the motor with the first connector and the second connector being fitted to each other, wherein
the first connector includes:
a tubular receiving portion made of resin,
a first conductive portion disposed inside the receiving portion, and
a first shield that is made of metal and is disposed between the receiving portion and the first conductive portion
the second connector includes:
a tubular insertion portion made of resin and insertable into the receiving portion,
a second conductive portion disposed inside the insertion portion and connected to the first conductive portion, and
a second shield that is made of metal and is disposed between the insertion portion and the second conductive portion, and
the insertion portion includes a distal end portion that is disposed adjacent to the first connector and a proximal end portion that is disposed opposite from the distal end portion in an insertion direction in which the insertion portion is inserted,
one of the first shield and the second shield has a convex portion projecting toward the other of the first shield and the second shield,
a rib is disposed between an inner surface of the receiving portion and an outer surface of the insertion portion and extends in the insertion direction, wherein the rib is formed integrally with one of the inner surface and the outer surface, and is in contact with the other of the inner surface and the outer surface,
one of the first connector and the second connector includes a shield support portion that is positioned in a projecting direction of the convex portion, wherein the other of the first shield and the second shield that does not have the convex portion is held between the shield support portion and the convex portion, the shield support portion causes the first shield and the second shield to be in contact so as to be electrically connected, and
the shield support portion is a projection that projects toward the convex portion and extends in the insertion direction so as to overlap with the rib across the insertion portion.
2. The electric compressor for the vehicle according to claim 1 , wherein
the inverter is accommodated in an inverter case,
the inverter case includes a case shield that is made of a metal and formed integrally with the second shield, and a resin case portion that is made of resin and overlaps the case shield, and
the insertion portion and the rib are formed integrally with the resin case portion.
