Electric Connector Shielding with Movable Plate for Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric connector devices face challenges in providing effective electromagnetic shielding for parts connected to wiring substrates, particularly at higher signal frequencies, and often require labor-intensive processes that complicate visual inspection and connection verification.
Innovation Solution
The proposed electric connector configuration includes a shield shell member with a fixed and movable shield plate, where the movable shield plate covers the substrate connecting leg portion of the contact member, establishing a ground connection via a conductive path on the wiring substrate, allowing for reliable electromagnetic shielding and easy visual inspection of connection states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an electrically-conductive shell is extended to cover the connected parts, then electromagnetic shielding is improved, but visual inspection and connection verification become difficult
Solution Approach 1:
The shield shell member is divided into a fixed shield plate portion and a movable shield plate portion. The movable shield plate can be separated from the fixed shield plate to expose the connected parts, allowing visual inspection while maintaining shielding capability when closed. This segmentation resolves the contradiction by enabling both shielding and inspection through spatial separation of functions.
2Object-affected harmful factors
If an electrically-conductive tape is pasted onto connected parts, then electromagnetic shielding is achieved, but productivity decreases due to labor-intensive operations
Solution Approach 1:
The movable shield plate is integrated with the shield shell member as a unified component rather than being a separate tape material. This merging eliminates the need for pasting operations, allowing the shield to be installed as a single piece that provides both shielding and inspection capabilities, thereby improving productivity while maintaining electromagnetic shielding effectiveness.
3Object-affected harmful factors
If the connected parts are completely covered for shielding, then electromagnetic shielding is improved, but connection verification becomes impossible
Solution Approach 1:
The shield shell member incorporates a movable shield plate that can dynamically change position between covering and exposing the connected parts. When closed, it provides complete shielding; when opened, it allows visual verification of connections. This dynamic capability resolves the contradiction by enabling both complete shielding and connection verification as needed.

AI summary
Electromagnetic shielding about a part connected with a wiring substrate is easily and reliably carried out by a simple configuration without impairing productivity. A fixed shield plate provided at a shield shell member of an electric connector mounted on a wiring substrate is disposed to be opposed to a vicinity of a substrate connecting leg portion of a contact member. A movable shield plate covering a shell opening by a moving operation is provided. At least the substrate connecting leg portion of the contact member is covered from an outer side by fixed and movable shield plates, thereby well carrying out electromagnetic shielding (shielding) with respect to the part connected with the wiring substrate. Until the movable shield plate is subjected to the moving operation, the part connected with the wiring substrate can be checked well through the shell opening.
