Lever Connector Locking Mechanism Against Accidental Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lever connectors do not effectively secure levers against accidental opening, which can disrupt electrical connections.
Innovation Solution
Incorporation of lock members that slide or rotate relative to the connector body to prevent inadvertent actuation of levers, ensuring secure clamping connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lever connectors are designed for rapid installation and reusability, then ease of operation and productivity are improved, but reliability deteriorates due to lack of securing mechanism against accidental opening
Solution Approach 1:
The lock member is designed to be movable between locked and unlocked positions, allowing the connector to transition between secure and accessible states. This dynamic element enables the system to maintain reliability when needed while preserving ease of operation during intentional access.
Solution Approach 2:
The lock member acts as an intermediary element between the lever and the external environment. It mediates access to the lever, requiring intentional action to overcome the locking mechanism, thus preventing accidental opening while maintaining the lever's functionality when properly accessed.
2Reliability
If lock members are added to prevent accidental opening, then reliability is improved, but device complexity increases
Solution Approach 1:
The lock member is integrated with the connector body and lever assembly, combining multiple functions into a single component. The lock member works together with the lever and body as a unified system, reducing the need for separate securing mechanisms and minimizing overall device complexity.
Solution Approach 2:
The lock member is designed to be manually operated by the user without requiring additional tools or complex mechanisms. The user directly manipulates the lock member to lock or unlock the lever, making the system self-sufficient and avoiding the need for separate locking devices or complex actuation systems.

AI summary
A lever connector includes a connector body, pivotable levers movable between open and closed positions to actuate clamping sites for securing conductors, and a lock member that is movably coupled to the connector body and configured to transition between a locked position, preventing lever actuation, and an unlocked position, permitting lever actuation. The lock member may slide or rotate relative to the connector body.
