Abstract

A motor-driven compressor and a housing for the motor-driven compressor are provided. A power line connector and a communication line connector are arranged on an external surface of a housing. A first terminal of an interlocking communication line is located in the power line connector. A second terminal of the interlocking communication line is located in the communication line connector. The interlocking communication line is routed on the external surface from the first terminal to the second terminal.

First claim

What is claimed is:

1. A motor-driven compressor, comprising:
a compression unit that compresses fluid;
an electric motor that drives the compression unit;
an inverter that drives the electric motor;
a housing that accommodates the compression unit, the electric motor, and the inverter;
a power line connector arranged on the housing, wherein the power line connector supplies power to the inverter when connected to a first vehicle-side connector;
a communication line connector arranged on the housing, wherein the communication line connector sends a control signal that drives the compression unit to the inverter when connected to a second vehicle-side connector; and
an interlocking communication line routed between the power line connector and the communication line connector, wherein the interlocking communication line includes a first terminal at one end and a second terminal at another end, and the interlocking communication line is connected to a vehicle-side interlocking wire when the power line connector is connected to the first vehicle-side connector and the communication line connector is connected to the second vehicle-side connector, wherein
the power line connector and the communication line connector are arranged on an external surface of the housing,
the first terminal of the interlocking communication line is located in the power line connector,
the second terminal of the interlocking communication line is located in the communication line connector, and
the interlocking communication line is routed on the external surface from the first terminal to the second terminal.

2. The motor-driven compressor according to claim 1 , further comprising a connection portion that integrally connects the power line connector to the communication line connector, wherein
the interlocking communication line is arranged inside the connection portion, and
the interlocking communication line is connected to the power line connector and the communication line connector.

3. The motor-driven compressor according to claim 1 , wherein
the housing includes
an accommodating recess that accommodates the inverter, and
an inverter cover that closes the accommodating recess, and

the external surface of the housing is an external surface of the inverter cover.

4. A housing for a motor-driven compressor, the housing comprising:
an external surface;
a power line connector arranged on the external surface;
a communication line connector arranged on the external surface; and
an interlocking communication line for connection to a vehicle-side interlocking wire when the power line connector is connected to a first vehicle-side connector and the communication line connector is connected to a second vehicle-side connector, wherein the interlocking communication line includes a first terminal located in the power line connector and a second terminal located in the communication line connector, wherein
the interlocking communication line is routed between the power line connector and the communication line connector on the external surface from the first terminal to the second terminal.
