Abstract

A wiring module includes: a common power supply line whose one end is electrically connected to a power source; and a power supply branch part provided halfway through the common power supply line, wherein the power supply branch part includes at least one group of a power supply branch line branched halfway through the common power supply line and an overcurrent blocking part provided in the power supply branch line to enter a non-continuity state when current exceeding allowable current flows in the power supply branch line. A wiring module is a wiring module disposed along a fixing target member, and includes: a power supply flat wiring body disposed along a surface of a fixing target member; and a ground flat wiring body disposed along a surface of the power supply flat wiring body on an opposite side from the fixing target member.

First claim

The invention claimed is:

1. A wiring module, comprising:
a common power supply line whose one end is electrically connected to a power source, and the common power supply line supplies power to a plurality of loads; and
a power supply branch part provided halfway through the common power supply line, wherein
the power supply branch part includes at least one group of a power supply branch line branched halfway through the common power supply line and an overcurrent blocking part provided in the power supply branch line to enter a non-continuity state when current exceeding allowable current flows in the power supply branch line, and the overcurrent blocking part is disposed between the common power supply line and only one of the plurality of loads,
the common power supply line includes a plurality of wiring bodies divided by the power supply branch part,
cross-sectional areas of the plurality of wiring bodies serially decrease with increasing distance from the power source, and
the common power supply line is disposed along a reinforcement while at least part of the common power supply line and at least part of the power supply branch part are housed in the reinforcement.

2. The wiring module according to claim 1 , wherein
the overcurrent blocking part includes a semiconductor switch.

3. The wiring module according to claim 1 , wherein
an electronic control part is incorporated into the power supply branch part.

4. The wiring module according to claim 1 , wherein
the common power supply line includes a flat wiring body disposed along a surface of the reinforcement.

5. The wiring module according to claim 1 , wherein
the power supply branch part includes a connector to connect the power supply branch line to a load among the plurality of loads.

6. The wiring module according to any one of claim 1 , wherein
a terminal portion of the common power supply line is connected to a load among the plurality of loads via a terminal portion power supply junction part.

7. A wiring module, comprising:
a common power supply line whose one end is electrically connected to a power source, and the common power supply line supplies power to a plurality of loads; and
a power supply branch part provided halfway through the common power supply line, wherein
the power supply branch part includes at least one group of a power supply branch line branched halfway through the common power supply line and an overcurrent blocking part provided in the power supply branch line to enter a non-continuity state when current exceeding allowable current flows in the power supply branch line, and the overcurrent blocking part is disposed between the common power supply line and only one of the plurality of loads,
the common power supply line includes a plurality of wiring bodies divided by the power supply branch part,
cross-sectional areas of the plurality of wiring bodies serially decrease with increasing distance from the power source, and
width dimensions of the plurality of wiring bodies coincide with each other, and thickness dimensions of the plurality of wiring bodies serially decrease with increasing distance from the power source, thus cross-sectional areas of the plurality of wiring bodies serially decrease.

8. The wiring module according to claim 7 , wherein
the common power supply line is disposed along a reinforcement while at least part of the common power supply line and at least part of the power supply branch part are housed in the reinforcement, and
the width dimensions of the plurality of wiring bodies coincide with a width dimension of a space where the reinforcement houses the plurality of wiring bodies.

9. A wiring module, comprising: a common power supply line whose one end is electrically connected to a power source, and the common power supply line supplies power to a plurality of loads; and a power supply branch part provided halfway through the common power supply line, wherein the power supply branch part includes at least one group of a power supply branch line branched halfway through the common power supply line and an overcurrent blocking part provided in the power supply branch line to enter a non-continuity state when current exceeding allowable current flows in the power supply branch line, and the overcurrent blocking part is disposed between the common power supply line and only one of the plurality of loads, the common power supply line includes a plurality of wiring bodies divided by the power supply branch part, cross-sectional areas of the plurality of wiring bodies serially decrease with increasing distance from the power source, the common power supply line is disposed along a reinforcement while at least part of the common power supply line and at least part of the power supply branch part are housed in the reinforcement, the power supply branch part includes a connector to connect for connecting the power supply branch line to a load among the plurality of loads, the power supply branch part is provided halfway through the plurality of wiring bodies, while the connector is exposed outside the reinforcement.

10. The wiring module according to claim 1 , wherein the overcurrent blocking part includes a current monitoring circuit to monitor current flowing in the power supply branch line, a semiconductor switch interposed in the power supply branch line, and an electronic controller to control the semiconductor switch based on a detection result of the current monitoring circuit.

11. The wiring module according to claim 1 , wherein the overcurrent blocking part includes a relay.

12. The wiring module according to claim 1 , wherein the overcurrent blocking part includes a fuse.
