POWER FEEDER FOR VEHICLE AND INTEGRATED WIRING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power feeder for a vehicle and an integrated wiring device which can reduce the number of power cables and prevent the occurrence of short-circuit abnormality. SOLUTION: A power cable 1a, covered with a conductor 1c, is made into a closed loop which departs from the point G connected to a battery 3 and returns to the point G again, passing through the specified positions within the vehicle body, and a plurality of control modules such as FIM5, etc., are connected at the specified points A,... in the loop, and it is supplied with power from the battery 3. Together with this, the conductor 1c, covering the power cable 1a, is cut off at each point A, and at every point, the sections are made independent as the conductor parts 1c-A to 1c-G, and those are connected individually to the abnormality-detecting circuit of each control module, thus it is so arranged as to detect the short-circuit abnormality, by detecting the voltage change separated for each conductor parts 1c-A to 1c-G, and is arranged so that it can specify which of the position of individual conductor parts 1c-A to 1c-G positions the abnormality is detected.
