Routing structure of high-voltage cable in vehicle

摘要

A routing structure of a high-voltage cable of a vehicle has a high-voltage cable (18) connected to an end surface of a motor (10) and routed along a motor case (13) by being extended from the connecting portion in one direction and then extended in the direction reverse to the one direction, and in which structure a first protector (41) configured to hold the high-voltage cable (18) and extended along the motor case (13) is supported on the motor case (13).

1. A routing structure of a high-voltage cable of a vehicle, the routing structure comprising: a power unit including a motor and a transmission that are operationally connected to each other; a rotary shaft of the motor and a output shaft of the transmission that are provided side by side so as to be separated from each other in the vehicle front-rear direction; a high voltage apparatus capable of inputting and outputting high-voltage power; a high-voltage cable for supplying the high-voltage power to the motor; a low voltage apparatus capable of inputting and outputting low-voltage power; and a low-voltage harness for supplying the low-voltage power,
wherein the routing structure further comprising a sub-frame which supports each side end of the power unit via a mounting mechanism and includes at least a cross frame portion extended along the power unit; wherein the high-voltage cable is connected to an end surface of the motor and is routed along a case of the motor by being extended from the connecting portion in one direction and then extended in the direction reverse to the one direction and is supported by a first protector that is extended along the motor case and supported on the motor case so that the position at which the extending direction of the high-voltage cable is changed from the one direction to the reverse direction is located in the vicinity of the mounting mechanism; wherein the high-voltage cable is supported by a second protector which is extended along the cross frame portion and is supported on the sub-frame; and wherein the first protector is arranged within a space having the front-rear width between the rotary shaft of the motor and the output shaft of the transmission.
