Floating Connector Core Structure for Misalignment and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty connectors face misalignment issues due to fixed cores, leading to damage and lack of waterproofing, allowing water vapor ingress.
Innovation Solution
The core is floatably installed in the housing, allowing movement perpendicular to the height direction, and includes sealing rings to prevent misalignment and water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core is fixed in the housing, then the connector structure is stable, but misalignment between mated connectors causes damage and prevents smooth mating
Solution Approach 1:
The core is changed from a fixed structure to a floating structure that can move dynamically. The core is installed in the housing without rigid fixation, allowing it to float and adjust its position automatically during the mating process, thereby accommodating misalignment between connectors.
Solution Approach 2:
The positional parameters of the core are changed from fixed to variable. By allowing the core to float, its position becomes adjustable within certain limits, enabling automatic alignment compensation when connectors are mated, thus preventing damage due to misalignment.
2Device complexity
If no waterproof structure is provided, then the connector structure is simple, but water vapor easily enters the interior causing damage and failure
Solution Approach 1:
A waterproof sealing ring is introduced between the housing and the installation panel. This flexible sealing element creates an effective barrier against water vapor ingress while maintaining a relatively simple overall structure, thus protecting the internal components from moisture damage.
3Adaptability or versatility
If the core is floatably installed to allow movement, then misalignment is compensated, but the core stability relative to the housing decreases
Solution Approach 1:
The core is designed with a floating installation structure that allows controlled movement. The core can float and adjust its position within the housing to compensate for misalignment during mating, while still maintaining adequate stability through the constraints of the housing structure.

AI summary
A connector includes a housing with a height direction, a core installed in the housing, and a terminal disposed in the core and extending along the height direction. The core is floatably installed into the housing and can be moved relative to the housing in a direction perpendicular to the height direction.
