Shield Wall Connector With Check Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board-connecting electric connectors with shield walls for EMI shielding make it difficult to visually check the connection state of contact members with the wiring board, leading to potential reliability issues due to obscured solder joints and assembly states.
Innovation Solution
A board-connecting electric connector design featuring a shield wall with ground connecting portions and lateral/check windows allows for visual inspection of contact members' connection state while maintaining electromagnetic shielding, with a configuration that includes a plate-shaped shield wall, plate-shaped protruding ground connecting pieces, and a planar cover with coupling portions and check windows.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a shield wall is provided to surround the outer periphery of the electric connector for electromagnetic shielding, then electromagnetic shielding performance is improved, but the connection state of contact members and the assembly state cannot be visually checked
Solution Approach 1:
The shield wall is segmented by providing openings (check windows) at specific positions, allowing visual inspection of contact member connections while maintaining electromagnetic shielding at other positions. The shield wall is divided into shielding portions and non-shielding portions to balance EMI protection with inspectability.
Solution Approach 2:
Different portions of the shield wall have different properties: some areas provide electromagnetic shielding while others (check windows) provide visual access. The ground connecting portions are strategically positioned to allow visual checking of contact member solder connections without compromising overall shielding effectiveness.
2Object-affected harmful factors
If the shield wall covers the contact members from the outer side for electromagnetic shielding, then electromagnetic shielding is improved, but reliability testing through visual inspection becomes difficult
Solution Approach 1:
The shield wall structure is segmented to include check windows that provide visual access to contact member connections, enabling reliability testing while maintaining shielding coverage at other positions.
Solution Approach 2:
The check windows act as intermediaries that allow visual inspection light to penetrate through the shield wall structure, enabling observation of contact member solder connections without removing the shield wall or compromising electromagnetic shielding integrity.
3Object-affected harmful factors
If ground connecting portions are provided in the shield wall for electromagnetic shielding, then shielding effectiveness is improved, but the connector structure becomes more complex
Solution Approach 1:
The ground connecting portions are merged with the shield wall structure, forming an integrated component that provides both electromagnetic shielding and ground connection functions simultaneously, reducing overall structural complexity.
Solution Approach 2:
The shield wall structure serves multiple functions: electromagnetic shielding, ground connection provision, and visual inspection enablement through check windows. The ground connecting portions are positioned to also serve as reference points for visual checking contact member connections.

AI summary
The connection state of contact members with respect to a wiring board can be easily visually checked by a simple configuration. A shield wall portion composed of an electrically-conductive member opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in a multipolar shape is provided; each of ground connecting portions provided in the shield wall portion is disposed at the part between the contact connecting portions, which are adjacent to each other; a lateral check window composed of the space which enables visual check of the contact connecting portions is formed in the interval region in which the ground connecting portions are adjacent to each other; an electromagnetic shielding function with respect to the contact connecting portions is obtained by the shield wall portion; and, at the same time, the connection state of the contact connecting portions with respect to the wiring board can be visually checked through the lateral check window provided in the shield wall portion.
