Insulating Protector Coupling Structure for Bus Bar Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupling structures for insulating protectors in connection modules are not optimized in terms of space usage, leading to potential flexure and instability in the coupling of power storage element groups.
Innovation Solution
A connection module design that integrates a lock portion and a guide portion, allowing for a two-component coupling structure that minimizes space usage, enhances stability, and restricts rotation, thereby reducing flexure and improving the alignment of insulating protectors around bus bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple separate components are used for coupling protruding parts, engagement portions, and guide structures, then the coupling function is achieved, but the space occupied by the coupling structure is not optimized and the structure becomes complex
Solution Approach 1:
The patent combines multiple separate coupling components (coupling protruding parts, engagement portions, guide structures) into an integrated coupling structure. The insulating protector itself is designed to include both the coupling protrusion and the engagement portion with guide features, eliminating the need for separate coupling components and reducing overall space occupation.
Solution Approach 2:
The insulating protector serves multiple functions: it provides electrical insulation, structural support for bus bars, and coupling/engagement functionality. By integrating the coupling features directly into the insulating protector, the component becomes multi-functional, reducing the total number of separate parts needed in the assembly.
2Volume of moving object
If a compact two-component coupling structure is used, then space is optimized and miniaturization is achieved, but the stability and reliability of engagement must be maintained
Solution Approach 1:
The coupling structure incorporates localized guide portions and engagement features with specific geometric properties optimized for stable mating. The guide portion includes tapered surfaces and positioning features that ensure reliable alignment and engagement, while the engagement portion has complementary shapes that prevent disengagement under operational loads.

AI summary
The present invention provides a connection module that allows miniaturization of a coupling structure for insulating protectors. A connection module includes a plurality of bus bars and a plurality of insulating protectors that insulate and hold the plurality of bus bars. Each of the insulating protectors includes at least one of a lock portion that includes a lock protrusion and that is provided for coupling with an adjacent insulating protector and a guide portion that guides the lock protrusion of the lock portion provided in the adjacent insulating protector such that the lock protrusion is engaged with the guide portion. The lock portion includes a guide receiving portion into which the guide portion is to be inserted, and the guide portion includes a lock engagement portion with which the lock protrusion is to be engaged.
