Connector Shielding Structure for EMI Blocking and Card Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face signal interference due to high-frequency noise generated when high-speed signals pass through connectors, and existing shielding structures often collide with module cards during insertion, making it difficult to provide effective coverage.
Innovation Solution
An electronic device with a shielding structure comprising a shielding frame and a detachable shielding cover, featuring elastic coupling units and strategically designed gaps and wedging portions to block interference signals while allowing module card insertion without collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding structure is provided to block interference signals, then signal interference is reduced, but the module card may collide with the shielding structure during insertion
Solution Approach 1:
The shielding structure is divided into two separate components: a shielding frame and a shielding cover. The shielding frame remains fixed to block interference signals, while the shielding cover is detachable and can be removed during module card insertion to prevent collision, then reattached after insertion to maintain shielding effectiveness.
Solution Approach 2:
The shielding cover is designed with detachable connection to the shielding frame, allowing it to be dynamically removed when module card insertion is needed and reattached when shielding is required. This dynamic configuration resolves the contradiction between maintaining continuous shielding and enabling unobstructed insertion.
2Ease of operation
If the shielding cover is detachably connected to the shielding frame, then module card insertion is facilitated, but the shielding structure may become loose or misaligned
Solution Approach 1:
The detachable connection separates the shielding cover from the shielding frame, allowing independent positioning of each component. This segmentation enables the cover to be removed for insertion while the frame maintains structural stability, and ensures precise repositioning of the cover without affecting overall structure.
Solution Approach 2:
The shielding cover is pre-aligned with the shielding frame through designed connection interfaces before detachment. This preliminary alignment ensures that when the cover is reattached after module card insertion, it automatically returns to the correct position, maintaining shielding effectiveness and structural stability without requiring complex adjustment procedures.

Function Achieved in This Case
The shielding structure effectively blocks interference signals, reducing noise and allowing convenient module card insertion and reconnection, providing a reliable shielding effect that can be repeatedly used.
Implementation Method 1
The shielding cover comprises a first elastic coupling unit, and the first elastic coupling unit is adapted to connect to a first side of the module card. The shielding frame comprises a second elastic coupling unit, which is adapted to connect to the second side of the module card.
