Integrated Conductive Part for Arc Breaker Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-voltage electrical current cut-off devices, such as branch circuit breakers, require multiple parts for sealing and potential supply, making them complex and costly to manufacture, especially when a single-piece containment part is used, as drilling is necessary to bring potential, which compromises sealing.
Innovation Solution
A single conductive part integrates both sealing and potential supply functions, reducing the number of components by forming a single part that serves as both the containment part and arcing horn, and includes snap-fastening mechanisms for secure attachment, allowing for a simplified design with reduced parts and constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the containment part is made in one piece, then manufacturing cost and assembly complexity are reduced, but sealing effectiveness deteriorates because drilling is necessary to bring potential, which compromises sealing
Solution Approach 1:
The patent merges the containment part and arcing horn into a single integrated component. The arcing horn is formed as an integral part of the containment part, eliminating the need for separate assembly and drilling operations while maintaining both sealing effectiveness and electrical potential supply functionality
Solution Approach 2:
The integrated containment part performs multiple functions simultaneously: it provides mechanical containment, maintains sealing integrity, and supplies electrical potential through the integrated arcing horn. This multi-functionality resolves the contradiction by eliminating the need for separate components
2Reliability
If multiple parts are used for sealing and potential supply, then sealing effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functional parts (containment part and arcing horn) into a single integrated component, reducing the total number of parts while maintaining both sealing and potential supply functions through the integrated design

AI summary
The apparatus has an extinguishing chamber (22) partially closed in a watertight manner by a lid. A control drive is brought manually or automatically in an opening position of mobile contacts (7). A conducting part (34) and an arcing horn are provided an electric potential above an arc extinction device (32). The conducting part comprises a portion (38) to be brought on an opening (33) of the extinguishing chamber that is placed in a containment part to ensure the sealing of the extinguishing chamber.
