VEHICULAR ELECTRIC COMPRESSOR

摘要

There is provided a vehicular electric compressor capable of discharging electric charges of a capacitor surely and quickly in the event of an impact. The vehicular electric compressor includes: a compressing unit; an electric motor for rotating the compressing unit; and a driving circuit for driving the electric motor. The driving circuit includes: a capacitor; a circuit board provided with an electrically discharging circuit for discharging electric charges accumulated in the capacitor; and a positive electrode interconnection and a negative electrode interconnection configured to electrically connect the capacitor and the circuit board to each other. The vehicular electric compressor further includes a conductive member configured to come into contact with the positive electrode interconnection and the negative electrode interconnection, which are connected to the capacitor, when the positive electrode interconnection and the negative electrode interconnection are moved upon application of external force to the capacitor.
