Abstract

A vehicle includes: an inverter; a high-voltage connector and a low-voltage connector that are connected to the inverter; and a wire harness arranged at the rear of the inverter. The high-voltage connector includes fixing members that fix the high-voltage connector to the inverter, and the fixing members have release portions. The low-voltage connector includes an extended section, and the extended section extends toward the wire harness and covers the release portions. An upper surface of the extended section declines rearward, and an upper surface rear end of the extended section is located below a center in a cross section of the wire harness.

Claims

1. A vehicle comprising:

a high-voltage power supply;

a low-voltage power supply;

a traveling motor;

an inverter mounted in a front space of the vehicle, the inverter configured to convert direct current power that is output from the high-voltage power supply to alternative current power and supply the alternative current power to the traveling motor;

a wire harness arranged at a rear of the inverter, the wire harness extending in a vehicle width direction;

a high-voltage power line configured to supply electric power of the high-voltage power supply to the inverter, the high-voltage power line including a high-voltage connector, the high-voltage connector connected to a rear surface of the inverter that faces a rear of the vehicle, the high-voltage connector including fixing members that fix the high-voltage connector to the inverter, and the fixing members having release portions;

a low-voltage power line configured to supply electric power of the low-voltage power supply to the inverter, the low-voltage power line including a low-voltage connector, the low-voltage connector being connected to an upper surface of the inverter, the low-voltage connector including an extended section, the extended section that extends toward the wire harness, the extended section that covers the release portions, an upper surface of the extended section that declines rearward, and an upper surface rear end of the extended section being located below a center in a cross section of the wire harness; and

a shutoff circuit configured to electrically shut off the high-voltage connector from the high-voltage power supply when the low-voltage connector is released from the inverter.

2. The vehicle according to claim 1, wherein

the inverter includes:

a capacitor configured to smooth a current that is supplied from the high-voltage power supply; and

a discharge circuit configured to discharge electric power from the capacitor when the vehicle is involved in a collision, the discharge circuit being configured to be operated by the electric power that is supplied via the low-voltage connector.

3. The vehicle according to claim 1, wherein an imaginary horizontal line extending from the upper surface rear end the wire harness extends through the wire harness;

and the upper surface of the extended section that declines rearward is inclined; and

, upon movement of the inverter rearward due to a shock during a collision, the wire harness is pushed upward by the inclined upper surface of the extended section.
