Solution Overview
Problem
Existing battery temperature sensor configurations face interference issues with tools during attachment to battery cell groups, requiring a structure to hold the temperature sensor without compromising connectivity of bus bars and other components.
Innovation Solution
A wiring module with an insulating protector that includes connection member holding portions and a temperature detection member, featuring a locking portion to secure the temperature detection element and prevent interference with tools, while maintaining reliable temperature detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a structure for holding the temperature sensor is provided on the module component, then the temperature sensor can be held securely, but it interferes with tools for connecting bus bars
Solution Approach 1:
The module component is divided into distinct functional areas: connection member holding portions for securing electrical connectors, and a separate temperature sensor holding portion for mounting the temperature sensor. This segmentation allows tools to access connection members without interference from the temperature sensor holding structure, while still providing secure mounting for the sensor.
Solution Approach 2:
The temperature sensor holding portion acts as an intermediary structure that mounts the temperature sensor at a location where it can detect temperature near connection members without physically blocking tool access to the connection members themselves. This intermediary positioning resolves the conflict between sensor mounting and tool operation.
2Ease of operation
If the temperature sensor is attached separately from the module component, then tool interference is avoided, but no holding structure is provided for the sensor
Solution Approach 1:
The temperature sensor holding portion is integrated into the module component as a unified structure. The holding portion is formed as part of the same molded component that holds connection members, combining multiple functions (connection member support and temperature sensor support) into a single integrated part rather than requiring separate mounting structures.
Solution Approach 2:
The module component is designed with multi-functionality: it simultaneously serves as a support structure for connection members and as a mounting structure for the temperature sensor. The single molded component performs multiple roles, eliminating the need for additional separate mounting hardware.
3Reliability
If elastic portions are integrally molded with the module component, then the temperature sensor is securely attached, but a resin module must be produced for each sensor configuration
Solution Approach 1:
The temperature sensor holding portion is pre-formed as an integral part of the module component during the molding process. This preliminary formation of the holding structure allows for easy attachment of the temperature sensor later without requiring separate production of resin modules for each sensor configuration.
Solution Approach 2:
The molding process parameters can be adjusted to accommodate different temperature sensor positions and configurations without changing the basic module structure. The integral holding portion is designed to accommodate variations in sensor placement through parameter changes in the molding process rather than requiring completely different resin module designs.

AI summary
A wiring module includes: an insulating protector that has connection member holding portions for holding connection members that electrically connect adjacent electrode terminals; and a temperature detection member that detects the temperature of one of the connection members. The temperature detection member has a temperature detection element, electrical wires that are connected to the temperature detection element, an element accommodating portion that accommodates the temperature detection element and from which the electrical wires extend, and a detection portion that is continuous with the element accommodating portion and is arranged to be in contact with the connection member. The insulating protector has a locking portion that locks the element accommodating portion on the outer side of the connection member holding portions.
