Connector Fitting Detection Member Deflection Regulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with fitting detection members are prone to unintentional separation due to excessive external forces, leading to potential unintended release of the connector fitting, which complicates workability and requires protective measures against impact and vibration.
Innovation Solution
The connector design includes a fitting detection member with a deflection regulator that moves between temporary and complete engagement positions, allowing controlled release of the fitting lock arm to prevent unintentional separation, ensuring the connector remains engaged until intentionally released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fitting detection member is designed to be separable from the housing by applying a force larger than the engagement force, then the workability when intentionally releasing the fitting is improved, but the fitting detection member may be unintentionally separated from the housing when excessively large external forces (impact, vibration) are applied
Solution Approach 1:
The invention divides the locking mechanism into two independent parts: a first locking part between the fitting detection member and first housing, and a second locking part between the fitting detection member and second housing. This segmentation allows the first locking part to be released easily for workability while the second locking part maintains reliability by preventing unintentional separation through a separate engagement mechanism.
Solution Approach 2:
The fitting detection member acts as an intermediary component that mediates between the two housing parts. It includes both a first locking part for easy release and a second locking part for secure engagement, thereby resolving the contradiction between ease of operation and reliability by providing two different locking mechanisms through the same intermediary component.
2Reliability
If the fitting detection member is made securely engaged to prevent unintentional separation, then the reliability is improved, but the workability when intentionally releasing the fitting deteriorates
Solution Approach 1:
The locking mechanism is segmented into two independent locking parts: the first locking part designed for easy release to improve workability, and the second locking part designed for secure engagement to improve reliability. This segmentation allows each part to optimize for its specific function without compromising the other.
Solution Approach 2:
The invention introduces dynamic characteristics by making the first locking part releasable through simple operations while the second locking part remains securely engaged. This dynamic design allows the system to switch between easy release mode (first locking part) and secure lock mode (second locking part) based on operational needs.

AI summary
A second locked part engaged with a second locking part releases a contact between detection protrustion and the second locking part located at a temporary engagement position at which the contact between the detection protrusion and the second locking part prevents a movement of a fitting detection member in a first direction and allows the fitting detection member to move in the first direction. A deflection regulator of the fitting detection member located at a complete engagement position at which a first locked part is engaged with a first locking part regulates a deflection amount of a fitting lock arm within a range in which an engagement between the second locking part and the second locked part is unreleasable while an engagement between the first locking part and the first locked part is releasable.
