Solution Overview
Problem
The existing configurations for holding bus bars in power storage modules are complex and inefficient, particularly in limited spaces, and require simplification for improved vehicle performance.
Innovation Solution
A connector module with connecting members and a holder that includes placing sections and restricting portions, allowing for secure attachment and positioning of bus bars without surrounding walls, minimizing removal and displacement risks, and optimizing material usage through punching processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surrounding walls are used to surround the connecting members, then the connecting members are securely held and isolated, but the device complexity increases and space utilization decreases
Solution Approach 1:
The holder is divided into multiple placing sections, each with its own restricting portions. This segmentation allows each section to independently secure a connecting member without requiring comprehensive surrounding walls, thereby reducing overall device complexity while maintaining securing reliability.
Solution Approach 2:
The invention extracts only the essential securing function from the surrounding walls, implementing it through localized restricting portions at specific positions. This removes the unnecessary complexity of complete surrounding walls while retaining the core function of preventing removal and displacement.
2Reliability
If surrounding walls are used to surround the connecting members, then the connecting members are securely held and isolated, but the space utilization and arrangement efficiency decrease
Solution Approach 1:
Instead of providing uniform surrounding walls along the entire length of connecting members, the invention applies restricting portions only at critical local positions where securing is needed. This local quality approach maintains securing reliability while minimizing space occupation and improving arrangement efficiency.
3Device complexity
If restricting portions are used instead of surrounding walls, then the configuration is simpler and space is better utilized, but the isolation between adjacent connecting members may be reduced
Solution Approach 1:
The holder acts as an intermediary structure that provides both placing sections for securing connecting members and maintains isolation between adjacent members. This intermediary structure achieves both configuration simplicity and adequate isolation without requiring complex surrounding walls.

AI summary
A power storage module includes a power storage component unit and a connector module. The power storage component unit includes power storage components including electric terminals positive terminals, negative terminals) on one side. The connector module is attached to the power storage component unit to electrically connect the power storage components. The connector module includes bus bars and a holder. The bus bars connect the electric terminals of the power storage components that are adjacent to each other. The holder holds the bus bars. The holder includes a bus bar holding surface that includes bus bar placing sections on which the bus bars are placed. The holder includes restricting receptacles and restricting tabs fitted to the bas bars placed on the bus bar placing sections to restrict removal of the bus bars from the holder and displacement of the bus bars from the bus bar placing sections.
