  "abstract": "A wire harness includes a first conductor path having a high priority in protection, a second conductor path having a priority in protection which is lower than that of the first conductor path, and an external member having a tubular shape and accommodating the first conductor path and the second conductor path altogether so as to protect them. The external member has a form in which the first conductor path is positioned farther away from a road surface than the second conductor path within a predetermined range in a longitudinal direction thereof.",
  "claims": [
    "1. A wire harness comprising: a first conductor path having a high priority in protection; a second conductor path having a priority in protection which is lower than that of the first conductor path; and an external member having a tubular shape and accommodating the first conductor path and the second conductor path altogether so as to protect them, wherein the external member has a form in which the first conductor path is positioned farther away from a road surface than the second conductor path within a predetermined range in a longitudinal direction thereof, and wherein the external member has a ceiling wall, a bottom wall, a left wall, and a right wall, in which the ceiling wall has a larger radius of curvature than the bottom wall.",
    "2. The wire harness according to claim 1, wherein a portion of the wire harness corresponding to the predetermined range of the external member is formed according to a routing length on an underside of a vehicle floor.",
    "3. The wire harness according to claim 1, wherein a voltage value of the first conductor path is higher than that of the second conductor path.",
    "4. The wire harness according to claim 1, wherein the first conductor path includes two conductor paths and the second conductor path includes one conductor path.",
    "5. The wire harness according to claim 1, wherein the first conductor path includes three conductor paths and the second conductor path includes two conductor paths.",
    "6. The wire harness according to claim 5, wherein the three conductor paths of the first conductor path are aligned laterally side by side.",
    "7. The wire harness according to claim 1, wherein upon an event that a vehicle rides on a curb or in an event that a foreign matter comes to collide with the wire harness from a road surface side, the second conductor path having the lower priority in protection is affected before the first conductor path having the high priority in protection is affected.",
    "8. The wire harness according to claim 7, wherein the second conductor path functions as it were a shield for the first conductor path, and when the second conductor path is subjected to impact, the impact so received is absorbed and dispersed by the second conductor path."

  "description_excerpt": "The present invention relates to a wire harness which is laid out in a motor vehicle and more particularly to a wire harness including at least two types of conductor paths including a high-voltage conductor path and a cylindrical external member which accommodates these conductor paths altogether for protection.\n\nIn recent years, hybrid electric vehicles and electric vehicles draw people's attention as environmentally friendly vehicles. Additionally, the propagation rate of environmentally friendly vehicles has been increasing. In hybrid electric vehicles and electric vehicles, a motor is mounted as a power source, and in order to drive the motor, for example, a battery and an inverter need to be electrically connected by means of a high-voltage (a high voltage) wire harness. A high-voltage wire harness includes a high-voltage electric wire which constitutes a high-voltage conductor path and an external member which accommodates this high-voltage electric wire.\n\nIn relation to high-voltage wire harnesses, a number of proposals have been made. As one example of those proposals, a wire harness is raised which is disclosed in Patent Literature 1 below.\n\nAccording to a related art, in an event that a hybrid electric vehicle or an electric vehicle rides on a curb or a foreign matter comes to collide with an under body of the hybrid electric vehicle or the electric vehicle from a road surface side, there are fears that an external member making up a wire harness is damaged, whereupon a high-voltage electric wire is cut.",
