Integrated Insulative Cover for Busbar Module Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing busbar module protection systems require separate covers for voltage detection wires and electrified parts, leading to increased administrative costs and complexity due to the need to manage and transport multiple articles during the assembly and installation process.
Innovation Solution
An integrated insulative cover design that combines the voltage detection wire accommodating part cover with the cover for electrified parts, featuring hinges and locking mechanisms to securely lock the side covers onto the central cover, allowing for easy expansion and folding, thus managing a single article and reducing administrative expenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate covers are used for voltage detection wires and electrified parts, then protection function is improved, but device complexity and administrative costs increase
Solution Approach 1:
The patent combines the wire protecting cover and the insulative cover into a single integrated cover structure. The wire protecting cover portion covers voltage detection wires, while the insulative cover portion covers electrified parts of busbars. This merging eliminates the need to manage separate articles, reducing administrative complexity while maintaining comprehensive protection functionality.
2Reliability
If separate covers are used for voltage detection wires and electrified parts, then protection function is improved, but administrative costs increase
Solution Approach 1:
By integrating the wire protecting cover and insulative cover into one article, the patent reduces the quantity of separate components that need to be managed, tracked, and assembled. This single integrated cover eliminates administrative overhead associated with managing multiple separate covers, thereby reducing administrative costs while maintaining dual protection functions.
3Device complexity
If integrated cover design is used, then device complexity is reduced, but protection reliability may worsen
Solution Approach 1:
The integrated cover is divided into distinct functional portions: a wire protecting cover portion for protecting voltage detection wires and an insulative cover portion for covering electrified parts of busbars. This segmentation within integration ensures that each protection function is properly addressed while maintaining the benefits of a unified structure that reduces overall device complexity.
4Stability of the object's composition
If fixed cover structure is used, then protection stability is improved, but ease of operation worsens
Solution Approach 1:
The cover incorporates a movable portion that can be moved between a first position where it covers a first busbar and a second position where it covers a second busbar. This dynamic design allows the cover to adapt to different operational states and access requirements while maintaining stable protection when in the covered position, thus balancing protection stability with operational ease.

AI summary
An insulative cover for covering a case of a busbar module is provided. The insulative cover includes a central cover and side covers. The central cover covers a voltage detection wire accommodating part of the case. The side covers cover busbar accommodating parts of the case. And the side covers are provided at opposite sides of the central cover with hinges between the central cover and the side covers, respectively. In a state where the side covers are folded onto the central cover through the hinges respectively, one and the other of the side covers are locked to each other with a first locking mechanism, respectively.
