A wire harness includes a first connector and a second connector respectively provided at opposite ends of a cable, protective members that are arranged side by side in a longitudinal direction of the cable and cover the cable, a first fixing member that is provided on the protective member closest to the first connector and configured to fix the wire harness to a mounting target, and a second fixing member that is provided on the protective member closest to the second connector and configured to fix the wire harness to the mounting target. The cable is covered with the protective members in an entire region between the first fixing member and the second fixing member. End portions of each pair of the protective members that are adjacent to each other in the longitudinal direction overlap with each other to slide on each other, thereby forming a sliding portion.

Wire harness and electric compressor

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.

Electric compressor for a vehicle

An electrically-driven compressor is installed on an engine. Refrigerant is compressed with rotation of a rotating shaft in a compression unit. An electric motor is coupled to the rotating shaft and drives the compression unit through the rotating shaft. A housing accommodates the compression unit, the electric motor, and the motor drive circuit aligned in the listed order in the axial direction of the rotating shaft. The housing is internally provided with the discharge chamber through which the refrigerant compressed by the compression unit is discharged. A weight is attached to the housing and disposed in the discharge chamber in a manner that a resonance frequency of the electrically-driven compressor is shifted relative to a resonance frequency of the engine, the weight including a material having a specific gravity greater than a specific gravity of a constituent material of the housing.
