Movable Shield Member Structure for Connector Gap Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with shield members face challenges in maintaining a consistent gap between the contact target and the shield member due to variations in distance, leading to potential electrical issues and requiring complex structures.
Innovation Solution
A shield member design featuring a base portion that remains stationary and a movable shield portion with a contact portion that generates pressure when pressed by a contact target, allowing for displacement to maintain a consistent gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed shield member structure is used, then the structure is simple, but gaps generate or increase due to distance variation between attachment target and contact target
Solution Approach 1:
The shield member incorporates a movable portion that can displace in the first direction in response to contact target pressure, transforming the fixed structure into a dynamic one. This displacement capability allows the shield member to automatically adjust and maintain consistent gap suppression despite variations in distance between the attachment target and contact target, resolving the contradiction between structural simplicity and gap reliability.
2Reliability
If a movable shield portion is added to suppress gaps, then gap suppression improves, but the shield member structure becomes more complex
Solution Approach 1:
The shield member is divided into a base portion and a movable portion that can independently displace. This segmentation allows the movable portion to specifically address gap issues through displacement while the base portion maintains the overall structural framework, achieving gap consistency without requiring complete structural redesign.
Solution Approach 2:
The shield member utilizes elastic deformation as a parameter change mechanism. The movable portion changes its physical state from rigid to elastically deformable, allowing it to displace in response to contact target pressure. This parameter change enables automatic gap adjustment without complex mechanical systems, balancing reliability improvement with structural simplicity.
3Ease of manufacture
If the shield member structure is simplified, then manufacturing cost decreases, but gap suppression capability is reduced
Solution Approach 1:
The movable portion of the shield member performs self-adjustment through elastic deformation in response to contact target pressure. This self-service mechanism automatically maintains gap suppression without requiring external control systems, complex actuators, or additional components, thereby achieving reliable gap control while keeping manufacturing costs low.

AI summary
A shield member includes a base portion that is not displaced with respect to an attachment object and a movable shield portion that is displaceable with respect to the base portion. The movable shield portion does not have a portion fixed to shield objects.
