Energy Storage Module Cable Housing With Integrated Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing module connection systems for energy storage systems face challenges in connecting sheathed cables between modules due to limited constructional space, making it difficult to both connect and seal against contamination and fluids, with known solutions like cable glands often complicating assembly.
Innovation Solution
A module connection system with variable fastening and sealing options, featuring at least two connection cover plates, connection housings, cable fasteners, and sealing elements, allowing for flexible orientation and secure sealing against environmental influences, including the use of a housing seal and cable glands with internal or external threads, and shaped fixing portions to prevent accidental release of fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable glands are used to seal cables against contamination and fluids, then sealing effectiveness is improved, but the module connection housing length increases making assembly difficult or impossible due to small constructional space
Solution Approach 1:
The cable fastener is integrated directly into the connection housing, with the sealing element nested within the housing structure. The cable fastener features an integrated sealing element that is received by a corresponding receiving structure in the connection housing, eliminating the need for external cable glands and reducing overall housing length while maintaining sealing effectiveness.
Solution Approach 2:
The patent combines the cable fastening function and sealing function into a single integrated cable fastener component. The cable fastener includes both the fastening mechanism and the sealing element, merging two previously separate functions into one compact component that fits within the limited constructional space.
2Reliability
If connection housings are designed to accommodate cable fasteners and sealing elements, then sealing against contamination is improved, but device complexity increases
Solution Approach 1:
The connection housing is designed with multi-functional features: it provides structural support, accommodates connection contacts, integrates cable fastening, and incorporates sealing capabilities. The housing includes integrated features such as receiving structures for cable fasteners, sealing element receptacles, and fluid communication paths, reducing the need for separate components and simplifying overall device complexity.
3Ease of operation
If multiple fastening orientations are provided for connection housings, then ease of assembly is improved, but device complexity increases
Solution Approach 1:
The connection housing features asymmetric fastening configurations with housing fastenings positioned at specific locations that enable multiple orientations. The housing can be fastened to the connection cover plate in different orientations (e.g., 0°, 90°, 180°, 270°) due to the strategic placement of fastening elements, allowing installers to choose the most convenient orientation while maintaining a relatively simple fastening mechanism.

AI summary
A module connection system for electrical energy storage systems includes at least two connection cover plates, at least two connection housings per connection cover plate, at least two cable fasteners, at least three cables and at least one sealing element. The connection cover plates each accommodate at least two connection contacts so that a connection can be established between at least two energy storage modules. The connection contacts are each surrounded by at least two connection fastenings which in tum are provided with connection housing fastenings for fastening the connection housing to a connection cover plate. The connection housings are also provided for accommodating a cable fastener and/or for accommodating a sealing element.
