Connector Seal Rib Notch Engagement Prevents Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector sealing structures require complex production methods to match the shape of the sealing member with the groove portion, making it difficult to curb sliding and rotation of the sealing member during connector insertion and rotation.
Innovation Solution
A connector sealing structure featuring a rib and notch configuration with a projection on the sealing member, where the projection engages the notch or rib, and a supporting member inside the projection to enhance rigidity and prevent rotation, allowing for effective regulation of sliding and rotation.

1Reliability
If a locking structure with groove portion and sealing member is used to prevent sliding and rotation, then sealing performance is improved, but production complexity increases due to the need for sophisticated technology to match shapes
Solution Approach 1:
The locking structure is divided into separate functional elements: the groove portion for positioning and the protrusion for rotation prevention. This segmentation allows each element to be designed and manufactured independently with simpler processes, while still achieving the combined function of preventing both sliding and rotation.
Solution Approach 2:
The groove portion and protrusion are designed with asymmetric geometries that complement each other. The groove has a specific cross-sectional shape that receives the protrusion, creating a mechanical interlock that prevents rotation without requiring the sealing member to match a complex groove shape throughout its entire circumference.
2Stability of the object's composition
If the groove portion and sealing member shapes are made to substantially match for effective locking, then sliding and rotation are prevented, but manufacturing sophistication and complexity increase
Solution Approach 1:
The rotation-preventing function is extracted from the sealing member and placed in the connector body as a separate protrusion element. This allows the sealing member to maintain its simple continuous ring shape while the protrusion provides the necessary geometric constraint against rotation, eliminating the need for complex shape matching.
Solution Approach 2:
The protrusion acts as an intermediary element between the groove portion and the sealing member. It translates the groove's positioning function into a rotation-prevention mechanism through its specific geometry, allowing the sealing member to engage without requiring sophisticated shape matching while still achieving stable locking.

AI summary
The outer peripheral surface of a connector, to which a connector seal structure is applied, is provided with an engaging section that engages with a seal member. A rib of the engaging section locks the seal member in the inserting direction of the connector. The seal member is provided with a cutout section formed by cutting out a part of the rib, or a protruding section that engages with the rib.
