Modular Electrical Apparatus Arc Protection Baffle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular electrical apparatuses face challenges in preventing electrical arcs and discharges between adjacent connection terminals and conductive cables, with existing protective baffles being difficult to install, prone to breakage, and causing obstacles during cable connection, leading to increased installation time and costs.
Innovation Solution
A modular electrical apparatus with movably constrained protective baffles that can be easily rotated into protective position, eliminating the need for complex alignment and insertion, and designed to protrude only when necessary for protection, reducing the risk of breakage and facilitating compact grouping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective baffles are installed separately and connected using small extensions and slots, then arc prevention protection is provided, but installation time and complexity increase significantly
Solution Approach 1:
The protective baffle is merged with the electrical apparatus by integrating it into the cable connection terminal structure. The baffle is now an integral part of the terminal assembly, eliminating the need for separate installation steps and reducing installation time while maintaining arc prevention protection.
Solution Approach 2:
The protective baffle is pre-installed and integrated into the electrical apparatus during manufacturing, rather than being installed separately by the user. This preliminary action eliminates the complex alignment and insertion steps required for separate baffle installation.
2Reliability
If protective baffles are connected using small extensions and slots, then arc prevention protection is provided, but the risk of breakage and disconnection increases
Solution Approach 1:
The protective baffle is merged with the electrical apparatus as an integral component rather than a separate attachable part. This integration eliminates the weak connection points (small extensions and slots) that are prone to breakage and disconnection.
Solution Approach 2:
The baffle structure is designed to be self-retaining through its integration with the terminal housing, eliminating the need for separate fixing mechanisms that can fail. The baffle automatically maintains its protective position without requiring additional fastening elements.
3Reliability
If protective baffles protrude from the electrical apparatus, then arc prevention protection is provided, but cable connection becomes more difficult
Solution Approach 1:
The protective baffle is designed with dynamic positioning capability, allowing it to be repositioned or adjusted during cable installation to accommodate cable routing requirements, then secured in its protective position. This dynamic characteristic resolves the conflict between providing arc protection and facilitating easy cable connection.

AI summary
A modular electrical apparatus (10) adapted to be installed inside an electric panel, comprising: a primary cased body (12); at least one electrical connection terminal (30) suitable for receiving an electrical conductive cable (32) for connecting the electrical apparatus (10) to said conductive cable; protective means (36, 38) for preventing electric arcs, which may be associated with said electrical connection terminal (30); and mechanical coupling means for coupling the protective means (36, 38) to said primary cased body (12. In particular, the mechanical coupling means allow to movably constrain the protective means (36, 38) to said primary cased body (12).
