Connector Locking Member Protection via Film Wiring Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connectors with open/close type locking members in electronic devices, particularly those using film-like wiring boards and printed wiring boards, face issues with the locking member shifting from a locked to an open state due to external factors, leading to connection failures and operational defects, especially during assembly and transportation.
Innovation Solution
Incorporating a protective member on the film-like wiring board that projects beyond the connector and functions as a shield, positioned opposite to the locking member, to prevent unintended contact and ensure the locking member remains in a locked state, enhancing operational efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an open/close type locking member is used in the connector, then the ease of operation is improved, but the reliability deteriorates because the locking member may shift from locked to open state due to external factors
Solution Approach 1:
The patent applies preliminary anti-action by providing a protective member that prevents external factors from acting on the locking member before unintended opening can occur. The protective member is positioned to block contact between external objects and the locking member, thereby preemptively preventing the harmful action that would cause the locking member to shift from locked to open state.
2Ease of operation
If the locking member is exposed to allow easy access, then the ease of operation is improved, but the object-affected harmful factors increase due to unintended contact
Solution Approach 1:
The patent uses an intermediary approach by introducing a protective member as a mediator between external objects and the locking member. This protective member allows the locking member to remain accessible for intended operation while blocking unintended contact from external factors, thus resolving the conflict between ease of operation and protection from harmful factors.
3Device complexity
If no protective member is provided, then the device complexity is reduced, but the reliability deteriorates due to connection failures from unintended locking member movement
Solution Approach 1:
The patent applies segmentation by dividing the connector system into distinct functional components: the locking member for operation and the protective member for protection. This segmentation allows each component to perform its specific function independently, adding minimal complexity while significantly improving reliability by preventing unintended locking member movement.

AI summary
The present invention prevents a connection defect of a connector. In an electronic device which includes a film-like wiring board and a printed wiring board on which a connector is mounted, the film-like wiring board includes a projecting portion which projects to a side opposite to the printed wiring board at a position where the film-like wiring board is exposed from the connector into which the film-like wiring board is inserted.
