Lever-Type Connector Detection Member for Fitting Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lever-type connectors require electrical examination to confirm fitting status, leading to potential mistakes and safety risks, as the lever position cannot be immediately judged before energization and may be accidentally moved to the cancellation side.
Innovation Solution
A lever-type connector with a detection member on the first housing that moves between positions to indicate complete or incomplete fitting, preventing accidental lever operation towards the cancellation side, allowing for immediate visual confirmation of the fitted condition without electrical examination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical examination is used to confirm fitting status, then the fitting condition can be detected, but the judgment cannot be made immediately before energization and safety risks increase
Solution Approach 1:
The patent replaces the electrical examination method with a mechanical detection member that visually indicates fitting status. The detection member moves between positions to show whether the lever is properly fitted, allowing immediate visual confirmation without waiting for electrical energization.
Solution Approach 2:
The detection member utilizes visual indication (potentially through color or position visibility) to show the fitting status. When the lever is properly fitted, the detection member moves to a visible position that immediately indicates proper fitting, eliminating the need for electrical examination.
2Reliability
If the lever position is confirmed by electrical signal, then the fitted condition can be judged, but the risk of accidental lever operation increases
Solution Approach 1:
The detection member serves as a mechanical intermediary between the lever position and the operator's knowledge of fitting status. It provides immediate visual feedback about the lever position, allowing the operator to confirm proper fitting before energization and prevent accidental operation.
Solution Approach 2:
The detection member provides preliminary visual confirmation of the lever position before electrical energization occurs. This allows the operator to verify proper fitting in advance and take preventive action against accidental lever operation.
3Loss of time
If visual confirmation of lever position is used, then immediate judgment is possible, but the detection mechanism adds complexity
Solution Approach 1:
The detection member is integrated into the existing connector structure and serves multiple functions: it detects the lever position, provides visual indication of fitting status, and potentially guides the lever operation. This multi-functionality reduces the need for separate detection systems and minimizes added complexity.
Solution Approach 2:
The detection function is merged with the lever mechanism itself. The detection member is positioned to move naturally with the lever's motion, combining the detection function with the existing mechanical structure rather than adding a separate complex detection system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures safe and immediate judgment of proper fitting without electrical examination, preventing accidental lever movement and enhancing safety and reliability by visually confirming the lever's operation status and maintaining the fitted condition.
Implementation Method 1
a detection member is mounted on the first connector housing, and is movable between a first position and a second position, and when the lever is pivotally moved to a completely-fitting operating position where the first and second connector housings are properly fitted together, the detection member can be moved from the first position to the second position
Implementation Method 2
a lever-type connector which is provided with a lever for assisting the fitting force. In the lever-type connector, the lever is pivotally mounted on one of a pair of connectors to be fitted together, and the lever, when pivotally moved, assists the two connector housings in fitting connection and disengagement relative to each other
Implementation Method 3
the lever, when pivotally moved, assists the two connector housings in fitting connection and disengagement relative to each other through the action of a cam mechanism
Implementation Method 4
the lever, when pivotally moved, assists the two connector housings in fitting connection and disengagement relative to each other through the action of a cam mechanism provided between the lever and the other connector housing

AI summary
In a lever-type connector, a lever 70 is pivotally mounted on a second connector housing 60, and by operating an operating portion 71 of the lever toward a fitting side, the second connector housing is fitted to a first connector housing 10. By operating the operating portion to a cancellation side opposite to the fitting side, the fitted condition is canceled. A detection member 50 is slidably mounted on the first connector housing. When the lever is pivotally moved to a completely-fitting operating position where the two connector housings are properly fitted together, the detection member can be slid, and the thus slid detection member tells a completely-operated condition of the lever, and also prevents the operating portion of the lever from being operated to be moved toward the cancellation side. When the lever is stopped in a half-fitting operating position before the completely-fitting operating position, the detection member interferes with the operating portion of the lever, and is prevented from sliding movement, and tells an incompletely-operated condition of the lever.
