Abstract
A cluster block is arranged on an outer peripheral surface of a stator core. A lead wire is continuous with a U-phase coil, which extends from a coil end of the stator core, and is then connected to a U-phase connector. A lead wire is continuous with a V-phase coil, which extends from the coil end, and is then connected to a V-phase connector. A lead wire is continuous with a W-phase coil, which extends from the coil end, and is then connected to a W-phase connector. The lead wires are twisted and entwined with one another.
Claims12
A motor-driven compressor comprising:
- an outer shell;
- an electric motor accommodated in the outer shell;
- a stator core and a plurality of phase coils that configure a stator of the electric motor;
- a cluster block arranged on an outer peripheral surface of the stator core;
- a plurality of lead wires, wherein the lead wires extend from the corresponding phase coils and are connected to connectors in the cluster block;
- and
- a displacement prevention means for preventing the lead wires from displacing to the inner side of the stator core,
- wherein the at least one of the lead wires crosses one other of the lead wires such that the lead wires restrain each other.
A wiring method for preventing displacement of a lead wire in a motor-driven compressor, the motor-driven compressor including an outer shell, an electric motor accommodated in the outer shell, a stator core and a plurality of phase coils that configure a stator of the electric motor, a cluster block arranged in the outer shell, a plurality of lead wires that extend from the corresponding phase coils and are connected to connectors in the cluster block, and a displacement prevention means for preventing the lead wires from displacing to the inner side of the stator core, the method comprising:
- a connecting step of connecting the lead wires to the connectors;
- a twisting step of twisting the lead wires by rotating the cluster block from a first temporary posture, in which the lead wires are connected to the connectors, to a second temporary posture after the connecting step;
- and
- an arranging step of arranging the cluster block on an outer peripheral surface of the stator core after the twisting step.
A wiring method for preventing displacement of a lead wire in a motor-driven compressor, the motor-driven compressor including an outer shell, an electric motor accommodated in the outer shell, a stator core and a plurality of phase coils that configure a stator of the electric motor, a cluster block arranged in the outer shell, a plurality of lead wires that are extended out from the corresponding phase coils and connected to connectors in the cluster block, and a displacement prevention means for preventing the lead wires from displacing to the inner side of the stator core, the method comprising:
- a braiding step of braiding the lead wires with one another;
- a connecting step of connecting the lead wires to the connectors;
- and
- an arranging step of arranging the cluster block on an outer peripheral surface of the stator core.
