Abstract

To supply electric power from a vehicle body (1) of an automobile having a high-voltage power supply line (6) to a door unit (2) serving as a fed member having a low-voltage power supply line (7) whose voltage is lower than that of the high-voltage power supply line, the vehicle body 1 is provided with a primary noncontact connector (4) having a primary coil (14) and connected to the high-voltage power supply line (6), and the door unit is provided with a secondary noncontact connector 5 having a secondary coil (25) in which a voltage-lowered induced electromotive force capable of being supplied to the low-voltage power supply line is generated due to the action of mutual induction as the primary coil is brought into close proximity to the secondary coil, the door member being connected to the low-voltage power supply line.

Claims

1. A feeder system for supplying electric power from a vehicle body of a vehicle to a fed member, the feeder system comprising:

a high-voltage power supply line, for supplying the electric power of first voltage, provided to the vehicle body;

a primary noncontact connector including primary coil and connected to the high-voltage power supply line;

a low-voltage power supply line, for supplying the electric power of second voltage lower than the first voltage, provided to the fed member; and

a secondary noncontact connector connected to the lower-voltage power supply line and including a secondary coil generating an induced electromotive force as the primary coil is brought into close proximity to the secondary coil, wherein the secondary coil converts the electric power of the first voltage supplied from the primary coil to the electric power of the second voltage in cooperation with the primary coil.

2. The feeder system according to claim 1, wherein the primary noncontact connector is detachable from the vehicle body, and the secondary noncontact connector is detachable from the fed member.

3. The feeder system according to claim 1, wherein

the primary noncontact connector includes a primary core around which the primary coil is wound,

the secondary noncontact connector includes a secondary core around which the secondary coil is wound, and

a winding ratio between the secondary coil and the primary coil is so set that the first voltage is converted to the second voltage.

4. The feeder system according to claim 1, wherein the first voltage is 36 V and the second voltage is 12 V.
