Connector Sealing Assembly for Faster Airtight Leakage Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard leakage tests for electrical connectors are time-consuming and difficult to perform because air is injected through the wires, making it challenging to ensure the connectors are airtight and protected against water and dust.
Innovation Solution
A sealing assembly that includes a cover with a through-hole for injecting air and a plug assembly with a single wire seal and locking elements, allowing for quick and efficient leakage testing by injecting air directly through the cover, rather than through the wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is injected through the wires during leakage tests, then the electrical component can be tested for airtightness, but the test process becomes time-consuming and difficult to perform
Solution Approach 1:
The invention extracts the air injection function from the wire system and relocates it to a dedicated through-hole in the cover. By removing the plug assembly, air can be directly injected through the through-hole into the electrical component, eliminating the need to inject air through the wires. This extraction of the air injection path from the wire system resolves the technical contradiction by enabling fast, reliable airtightness testing without time-consuming wire-based injection procedures
2Reliability
If air is injected through the wires during leakage tests, then the electrical component can be tested for airtightness, but the operation becomes difficult to perform
Solution Approach 1:
The invention extracts the air injection function from the wire system and relocates it to a dedicated through-hole in the cover. By removing the plug assembly, air can be directly injected through the through-hole into the electrical component, eliminating the need to inject air through the wires. This extraction of the air injection path from the wire system resolves the technical contradiction by enabling fast, reliable airtightness testing without time-consuming wire-based injection procedures
Solution Approach 2:
The through-hole in the cover serves as an intermediary structure that facilitates air injection directly into the electrical component. This intermediary element provides a dedicated, easy-to-access pathway for air injection, replacing the complex wire-based injection method and significantly improving the ease of operation while maintaining reliable airtightness detection
3Productivity
If a plug assembly with locking elements is used to seal the through-hole, then the electrical component can be quickly sealed and unsealed for testing, but the device complexity increases
Solution Approach 1:
The sealing assembly is segmented into distinct functional components: a cover with a through-hole, a plug assembly with a single wire seal, and locking elements. This segmentation allows each component to perform its specific function independently - the cover provides the sealing surface, the plug assembly with single wire seal provides the sealing mechanism, and the locking elements provide the reversible engagement. This segmentation enables quick sealing and unsealing operations while keeping the overall device complexity manageable through modular design

AI summary
A sealing assembly for sealing an electrical component having an opening includes a cover coupled with the electrical component and a plug assembly fixed to the cover. The cover has a through-hole for injecting air during leakage tests of the electrical component and a plurality of engaging elements. The plug assembly has a single wire seal sealing the through-hole and a plurality of locking elements reversibly engaging the engaging elements. The cover seals the opening of the electrical component in an air-tight manner when the plug assembly is inserted into the through-hole.
