IC Card Receptacle Connector with Removable Shielding and Insulating Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IC card receptacle connectors face issues with inadequate insulation between the shielding member and metal shield, leading to noise interference and dust penetration, causing short circuits, and are inconvenient to disassemble when components are damaged.
Innovation Solution
A receptacle connector assembly with a removable shielding member and a supporting member made of insulating material, featuring a locking mechanism and mounting mechanism to ensure secure attachment and easy replacement, preventing dust ingress and meeting PCMCIA insulation specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive is employed to secure the shielding member to the header housing, then the shielding member is fixed in place, but it becomes difficult to remove and replace when components are damaged
Solution Approach 1:
The shielding member is divided into multiple sections with resilient tabs that can be independently flexed. This segmentation allows the shielding member to be detached by flexing the tabs away from the housing walls, enabling easy removal and replacement without damaging the adhesive bond or the shielding member itself.
Solution Approach 2:
The shielding member incorporates resilient tabs that can dynamically change their attachment state. In the normal state, the tabs are pressed against the housing walls to provide stable fixation. When removal is needed, the tabs can be flexed away from the walls, transitioning from a fixed state to a removable state, thus resolving the contradiction between stability and replaceability.
2Reliability
If the shielding member is firmly attached to the header housing, then insulation and noise shielding are maintained, but the assembly becomes complex and difficult to disassemble for repairs
Solution Approach 1:
The attachment mechanism is segmented into multiple resilient tabs distributed along the shielding member. Each tab can be independently flexed to facilitate removal, simplifying the disassembly process while maintaining reliable insulation and noise shielding when properly assembled.
Solution Approach 2:
The resilient tabs provide a dynamic attachment mechanism that is simple in structure but effective in function. The tabs naturally maintain contact with the housing walls for reliable insulation and shielding, yet can be easily displaced when removal is needed, reducing assembly complexity without compromising reliability.
