Waterproof USB Type-C Connector Assembly with Sealed Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB Type-C connectors lack a waterproof function, which is essential for protecting electronic devices from water and liquid ingress.
Innovation Solution
The electrical connector assembly incorporates an insulative housing, terminal modules, a metallic shell, and a waterproof material sandwiched between the housing and shell, along with a waterproof ring and glue to create a sealed environment, allowing the connector to be symmetrical and reversible while preventing water entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional USB Type-C connector structure is used, then the connector achieves basic electrical connection function, but it lacks waterproof function and cannot prevent water ingress
Solution Approach 1:
The waterproof ring is nested within the connector assembly, positioned between the insulative housing and metallic shell. This nested structure integrates the waterproofing function into the existing connector components without requiring a separate external waterproofing system, thus improving reliability while controlling complexity
Solution Approach 2:
The connector assembly combines multiple materials with different properties: insulative housing material, metallic shell material, and elastomeric waterproof ring material. This composite approach allows each material to perform its specific function (structural support, electrical connection, waterproofing) effectively, achieving waterproof function without excessive structural complexity
2Reliability
If additional waterproof components are added to the connector, then waterproof effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The waterproof ring is pre-installed into a groove on the insulative housing before the metallic shell is assembled. This preliminary action ensures proper positioning and sealing alignment, making the final assembly straightforward and maintaining ease of manufacture while achieving effective waterproofing
Solution Approach 2:
The waterproofing function is segmented into a dedicated waterproof ring component rather than being integrated into the main housing or shell. This segmentation allows the waterproof ring to be manufactured separately using optimal elastomeric materials and then easily installed, improving waterproof effectiveness without significantly complicating the overall manufacturing process
