Abstract

A wiring module includes a flexible substrate, a sensor component (temperature sensor), a connecting member (bus bar), and a holding part-equipped relay member, wherein the holding part-equipped relay member includes: a relay member main body including a base part (first main plate) that is to be fixed to the flexible substrate and the bus bar, and a holding part (first holding piece) that is continuous with the first main plate; a pedestal part (housing) that is to be held by the first holding piece so as to be displaceable in a direction toward or away from the first main plate, and that is to be fixed to a position of the flexible substrate where the temperature sensor is mounted; and a biasing member that has elastic force, that has one end held by the first main plate, and that biases the housing in the direction away from the first main plate.

First claim

1 . A wiring module that is to be attached to a power storage element including electrodes; comprising a flexible substrate;
a sensor component mounted to the flexible substrate; a connecting member that is to be fixed to the electrodes; and a holding part-equipped relay member that connects the flexible substrate and the connecting member to each other, and that holds the sensor component, wherein the holding part-equipped relay member includes: a relay member main body including a base part that is to be fixed to the flexible substrate and the connecting member, and a holding part that is continuous with the base part; a pedestal part that is to be held by the holding part so as to be displaceable in a direction toward or away from the base part, and that is to be fixed to a portion of the flexible substrate where the sensor component is mounted; and a biasing member that has elastic force, that has one end held by the base part, and that biases the pedestal part in the direction away from the base part.

2 . The wiring module according to claim 1 ,
wherein the relay member main body is a single member including the base part and the holding part.

3 . The wiring module according to claim 1 ,
wherein the relay member main body includes the base part, and the holding part that is a member separate from the base part and that is to be fixed to the base part.

4 . The wiring module according to claim 1 ,
wherein the wiring module is a vehicle wiring module that is to be used mounted in a vehicle.

5 . A power storage module comprising:
a power storage element including electrodes; and a wiring module that is to be attached to the power storage element, wherein the wiring module includes: a flexible substrate; a sensor component mounted to the flexible substrate; a connecting member that is to be fixed to the electrodes; and a holding part-equipped relay member that connects the flexible substrate and the connecting member to each other, and that holds the sensor component, and the holding part-equipped relay member includes: a relay member main body including a base part that is to be fixed to the flexible substrate and the connecting member, and a holding part that is continuous with the base part; a pedestal part that is to be held by the holding part so as to be displaceable in a direction toward or away from the base part, and that is to be fixed to a portion of the flexible substrate where the sensor component is mounted; and a biasing member that has elastic force, that has one end held by the base part, and that biases the pedestal part in the direction away from the base part.

6 . The power storage module according to claim 5 ,
wherein the power storage module is a vehicle power storage module that is to be used mounted in a vehicle.

7 . The wiring module according to claim 2 ,
wherein the wiring module is a vehicle wiring module that is to be used mounted in a vehicle.

8 . The wiring module according to claim 3 ,
wherein the wiring module is a vehicle wiring module that is to be used mounted in a vehicle.
