Movable Shield Contact Structure for Gap-Free Connector Shielding
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, especially due to variations in distance, which can lead to inefficiencies and increased complexity in design.
Innovation Solution
A shield member design that includes a base portion fixed to the attachment target and a movable shield portion with a contact portion that generates pressure when pressed by the contact target, allowing for displacement and maintaining contact even with variations in distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed shield member is used, then the structure is simple, but gaps are generated between the contact target and shield member due to distance variations
Solution Approach 1:
The shield member is designed with a movable portion that can displace in the first direction in response to contact with the contact target. This dynamic capability allows the shield member to maintain consistent contact despite variations in distance, resolving the contradiction between contact reliability and structural simplicity.
2Reliability
If a movable shield member is used to maintain contact, then gap generation is suppressed, but the structure becomes more complex
Solution Approach 1:
The shield member is divided into a base portion and a movable portion. The movable portion is configured to displace independently in the first direction when contacted by the contact target, while the base portion remains fixed. This segmentation allows the shield member to maintain contact consistency without requiring complete structural complexity.
3Reliability
If distance variations are accommodated, then shielding performance is maintained, but manufacturing cost increases
Solution Approach 1:
The movable portion of the shield member provides automatic adaptation to distance variations through displacement in the first direction, eliminating the need for complex adjustment mechanisms or precision manufacturing requirements. This dynamic design maintains shielding performance while keeping manufacturing costs low.

AI summary
A shield member includes a base portion and a movable shield portion that is displaceable with respect to the base portion. The movable shield portion has a contact portion configured to come into contact with a contact target as a result of bringing the contact target and the shield member close to each other in a first direction. The contact portion is configured such that a contact pressure is generated in the first direction by the contact with the contact target. The movable shield portion is configured to be displaced in the first direction when the contact portion is pressed by the contact target in the first direction.
