RF Connector Waterproof Gasket Compression via Shell Convex Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF connectors face challenges in achieving a sufficient waterproof effect due to the inefficiency of using separate waterproof gaskets for each plug terminal, which is labor-intensive and results in inadequate compression when a single gasket is used to cover all terminals.
Innovation Solution
The design incorporates an outer shell with a partition wall and convex structures that push the connector toward the partition wall, sandwiching a waterproof gasket between the connector's sides and the partition wall, enhancing the gasket's compression and tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate waterproof gaskets are disposed for each plug terminal, then the waterproof effect is improved, but the assembly complexity and labor time increase
Solution Approach 1:
Multiple separate waterproof gaskets for individual plug terminals are merged into a single integrated waterproof gasket that surrounds all plug terminals collectively. This reduces the number of separate components and simplifies assembly while maintaining waterproof protection across all terminals through the unified gasket structure.
Solution Approach 2:
The single waterproof gasket serves multiple functions by providing waterproof protection for all plug terminals simultaneously. Instead of each gasket serving only one terminal, the universal gasket design allows one component to perform the waterproofing function across multiple terminals, reducing assembly steps.
2Ease of manufacture
If one large waterproof gasket is disposed to surround all plug terminals, then the assembly is simplified, but the compression and tightness are insufficient
Solution Approach 1:
The outer shell is divided into an upper shell and a lower shell that are positioned relative to each other, with the single waterproof gasket disposed between them. This segmentation allows the gasket to be compressed uniformly between the two shell portions, ensuring adequate tightness and compression across the entire gasket while maintaining simplified assembly.
Solution Approach 2:
The waterproof gasket is positioned in a dimensional space between the upper and lower shells, utilizing the vertical dimension for compression. By arranging the gasket between two opposing shell surfaces, the design achieves uniform compression force distributed across the gasket's entire surface area, ensuring adequate tightness without requiring multiple separate gaskets.
3Reliability
If the connector is pushed toward the partition wall by convex structures, then the gasket compression is enhanced, but the structural complexity increases
Solution Approach 1:
Convex structures are added locally to the inner wall of the outer shell at specific positions where enhanced compression is needed. These localized convex features push against the connector body to apply focused compression force on the waterproof gasket, ensuring adequate tightness only where required rather than uniformly across the entire structure, thus minimizing added complexity.
Solution Approach 2:
The convex structures serve as intermediary elements between the outer shell and the connector body. Instead of directly modifying the connector or using complex fastening mechanisms, the convex structures act as mediators that transmit compression force from the outer shell to the connector, indirectly enhancing gasket compression through a simple geometric feature.

Function Achieved in This Case
This configuration ensures a tighter seal around the plug terminals, significantly improving the waterproof effect without the labor-intensive assembly of separate gaskets.
Implementation Method 1
the convex structures abut the second side, and the waterproof gasket is clamped and sandwiched between the first side and the partition wall by the convex structures pushing the connector toward the partition wall

AI summary
A radio frequency connector includes an outer shell, a connector and a waterproof gasket. The outer shell is provided with partition walls opposite to each other and convex structures protruding toward the partition walls. The first side of the connector is provided with a plurality of plug terminals. The waterproof gasket is disposed surrounding all the plug terminals. When the connector is accommodated in the outer shell, the plug terminal is received corresponding to the through hole of the partition wall. The convex structures abut the second side opposite to the first side to push the connector toward the partition wall for reducing the distance between the first side and the partition wall. Thus, the waterproof gasket can be tightly sandwiched between the first side and the partition wall to enhance the waterproof effect.
