Waterproof Connector Covering Structure for Reliable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof connectors often experience water leakage due to o-rings interfering with housing or internal components during assembly, leading to improper positioning.
Innovation Solution
A waterproof connector design featuring a rubber waterproof covering member with an adhesive overflow groove and ribs on its outer surface, which covers both the connector and circuit board, ensuring effective sealing by abutting against the housing and mechanical members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an o-ring is used to provide waterproofing, then waterproofing function is improved, but assembly reliability deteriorates due to interference with housing or internal components
Solution Approach 1:
The patent replaces the conventional o-ring with a waterproof covering member that has a flexible plate-like structure. This covering member can deform elastically during assembly to adapt to the connector and surrounding components, providing waterproofing without the circular interference problems of traditional o-rings. The flexible plate structure conforms to the specific geometry of the connector assembly, ensuring reliable sealing while avoiding interference with housing or internal components.
2Object-affected harmful factors
If a waterproof covering member is added to cover the connector, then waterproofing is improved, but device complexity increases
Solution Approach 1:
The waterproof covering member is integrated with the connector as a unified assembly. The covering member is positioned to cover the connector body and extends to seal against the housing, merging the waterproofing function directly into the connector structure rather than being a separate component. This integration simplifies the overall device complexity while maintaining effective waterproofing.
