Rotating Actuator Cable Connector for Flexible PCB
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable connectors for flexible printed circuit boards often disconnect when subjected to pulling forces or bending moments greater than a predetermined value, leading to unreliable electrical connections.
Innovation Solution
A cable connector design featuring a rotating actuator member with a slanted pressing surface and a positioning mechanism that ensures the flexible printed circuit board terminal remains securely connected by maintaining a closer position to the inner wall of the connector body, even under increased loads, while allowing for a sufficient opening angle for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuator member is positioned closer to the terminal section of the flexible printed circuit board, then the reliability of electrical connection is improved, but the opening angle of the inserting port is reduced making attachment and detachment difficult
Solution Approach 1:
The actuator member is positioned in the depth direction (Z-axis) of the connector body rather than only in the lateral direction, allowing it to be located closer to the terminal section without reducing the lateral opening angle of the inserting port. This spatial repositioning resolves the contradiction by utilizing the third dimension to achieve both reliable connection and easy operation.
2Strength
If the actuator member is positioned closer to the terminal section of the flexible printed circuit board, then the resistance to pulling force and bending moment is improved, but the opening angle of the inserting port is reduced
Solution Approach 1:
The actuator member is repositioned along the depth direction of the connector body, allowing it to be located closer to the terminal section to resist pulling forces and bending moments effectively, while the inserting port maintains its lateral opening angle for easy cable insertion and removal.
3Ease of operation
If a large opening angle is provided for the inserting port, then the ease of attachment and detachment is improved, but the stability of the locked state is reduced
Solution Approach 1:
The actuator member is positioned in the depth direction of the connector body, allowing the inserting port to maintain a large lateral opening angle for easy cable attachment and detachment, while the actuator member remains effectively positioned to provide stable locking through its depth-wise location near the terminal section.
