Rotatable Cover Electrical Connector with Stopper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in securely mounting and disconnecting flexible printed circuits (FPCs) due to limited rotation range and interference with surrounding components, particularly in narrow spaces, which can lead to accidental opening or failure to secure the connection.
Innovation Solution
The electrical connector design incorporates a rotatable cover member with a stopper mechanism, including protruding pieces on the top plate and a rotation shaft, to restrict the cover's rotation range and ensure secure engagement with the FPC, while allowing easy operation for connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover member is made rotatable to enable easy connection and disconnection of FPC, then the ease of operation is improved, but the rotation range may cause accidental opening or interference with surrounding components
Solution Approach 1:
The patent changes the rotation parameter by introducing a stopper mechanism that limits the rotation angle of the cover member. The stopper portion prevents the cover from rotating beyond a predetermined angle, ensuring reliable connection while avoiding accidental opening. This parameter control allows the cover to rotate sufficiently for operation but restricts excessive rotation that would cause reliability issues.
2Ease of operation
If the cover member rotates freely to allow easy access, then the ease of operation is improved, but interference with surrounding components in narrow spaces occurs
Solution Approach 1:
The stopper mechanism controls the rotation parameter of the cover member, limiting it to a predetermined angle that is sufficient for accessing the insertion opening but does not cause interference with surrounding components. This parameter optimization allows easy operation within the constraints of narrow installation spaces.
3Reliability
If the cover member is restricted in rotation to prevent accidental opening, then the reliability is improved, but the ease of operation for connection and disconnection deteriorates
Solution Approach 1:
The stopper portion is designed to restrict rotation only beyond the predetermined angle, while allowing sufficient rotation range for normal connection and disconnection operations. This selective parameter control maintains ease of operation for intended use while preventing accidental opening through rotation limitation.

AI summary
The electrical connector includes a main body including an insertion opening into which a connection target is inserted and an accommodation space to accommodate the connection target inserted into the insertion opening, conductive contact held in the main body so as to be connected to the connection target in the accommodation space, a cover member rotatably mounted on the main body so as to be rotatable around a rotation axis passing through the main body, and a stopper portion which restricts a rotation range of the cover member with respect to the main body.
