Electrical Connector Automatic Return Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors for flat conductive members require manual rotation of a movable member to switch between open and close positions, making it cumbersome to connect and disconnect multiple electronic components, especially when the movable member obstructs other components on the circuit board and needs to be repeatedly rotated for each connection.
Innovation Solution
The electrical connector is designed with a movable member that automatically rotates back to the close position after the flat conductive member is pulled out, utilizing a pressure receiving portion and an engaging portion to facilitate easy pull-out and automatic return, and an urging member to maintain the open position until a significant pull-out force is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable member is manually rotated to switch between open and close positions, then the connector can be securely connected or disconnected, but the operation becomes cumbersome and time-consuming when connecting multiple components
Solution Approach 1:
The movable member automatically rotates back to the close position after being pulled out, without requiring manual intervention. The pressing member applies automatic pressing force to the flat conductive member, eliminating the need for manual rotation and pressing operations, thereby improving operational convenience while maintaining connection reliability
Solution Approach 2:
The movable member is pre-configured with a pressing member that automatically applies pressing force when the flat conductive member is inserted. The automatic return mechanism is pre-set to rotate the movable member back to the close position after pull-out, ensuring reliable connection without requiring manual operation during the connection process
2Ease of operation
If the movable member remains in the open position after pull-out, then the flat conductive member can be easily removed, but the movable member obstructs other components on the circuit board
Solution Approach 1:
The movable member is pre-configured with an automatic return mechanism that rotates it back to the close position after the flat conductive member is pulled out. This preliminary setup ensures that the movable member automatically moves out of the obstructing position without requiring manual intervention, eliminating the harmful obstruction effect while maintaining easy disconnection
Solution Approach 2:
The system provides automatic feedback through the urging member that detects when the flat conductive member has been pulled out and triggers the movable member to rotate back to the close position. This feedback mechanism ensures the movable member automatically returns to its non-obstructing position, preventing interference with other circuit board components
3Ease of operation
If manual rotation is required for each connection, then precise control is achieved, but productivity decreases due to repeated manual operations
Solution Approach 1:
The movable member and pressing member work together in a self-service manner where the pressing member automatically applies pressing force and the movable member automatically rotates back to the close position after each connection. This eliminates the need for repeated manual rotation operations, significantly improving assembly efficiency while maintaining precise connection control through the automatic pressing mechanism
Solution Approach 2:
The pressing member is pre-positioned to automatically apply pressing force when the flat conductive member is inserted, and the movable member is pre-configured with an automatic return mechanism. This preliminary setup ensures that each connection operation is completed automatically without manual intervention, improving productivity while maintaining connection precision through the controlled pressing action

AI summary
An electrical connector is to be connected to a flat conductive member. The electrical connector includes a housing including a receiving portion for receiving the flat conductive member; terminals arranged in the housing in a terminal arrangement direction; and a movable member rotatable between an open position and a close position relative to the housing. The movable member includes an engaging portion for engaging an engaged portion when the movable member is situated at the close portion. The movable member includes a pressure receiving portion for abutting against the engaged portion when the movable member is situated at the open portion. The movable member includes a passing allowing space between the engaging portion and the pressure receiving portion for allowing the engaged portion to pass through. The engaged portion passes through the passing allowing space when the movable member is rotated toward the close position.
