Connector Moving Plate Detection Through Rear Projecting Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with moving plates face challenges in reliably detecting the state of the moving plate due to the flexibly deforming frame portion being exposed and prone to deflection, making it difficult to confirm the posture change and leading to unreliable detection.
Innovation Solution
The connector design includes a moving plate with a projecting portion that passes through a through hole in the housing, maintaining an unlocked state and being exposed rearward, allowing for visual detection of its posture and movement, thereby improving the reliability of state detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the flexibly deforming frame portion is exposed on the side surface of the housing body to visually confirm the state change of the moving plate, then the visibility of the moving plate state is improved, but the frame portion itself deflects and deforms during movement, causing unreliable detection
Solution Approach 1:
The invention separates the detection function from the moving plate structure by introducing a dedicated detection plate that is distinct from the moving plate. The detection plate includes a detection portion that visually indicates the state, while the moving plate focuses on its primary function of protecting tabs and moving between positions. This segmentation allows the detection mechanism to be optimized for visibility without compromising the structural integrity and stability of the moving plate components.
Solution Approach 2:
The invention introduces a detection plate as an intermediary element between the moving plate and the visual detection system. The detection plate includes a detection portion that responds to the state of the moving plate and provides visual feedback through color changes or positional shifts. This intermediary allows for reliable state detection without requiring the moving plate itself to provide visual cues, thereby maintaining the stability and structural integrity of the moving plate while achieving reliable detection.
2Reliability
If the moving plate is used to protect tabs and position them in the receptacle, then the tab protection function is improved, but the moving plate cannot be reliably used for state detection due to its deflection during movement
Solution Approach 1:
The invention divides the functionality into separate components: the moving plate is dedicated to protecting and positioning tabs, while a separate detection plate handles state detection. The detection plate includes a detection portion that provides visual feedback about the connector state. This functional segmentation ensures that the moving plate maintains its structural integrity for tab protection while the detection plate provides reliable visual state indication without being compromised by movement-induced deflection.
3Measurement precision
If the projecting portion is maintained unlocked to the housing and exposed rearward, then the visual detection of posture and movement is improved, but the structure becomes more complex with additional components
Solution Approach 1:
The detection plate serves multiple functions: it acts as a structural component of the connector assembly, provides visual state indication through its detection portion, and guides the insertion process. The detection portion can be integrated into the housing structure or the moving plate assembly, allowing it to serve both as a detection mechanism and as part of the overall connector structure. This multi-functionality reduces the need for separate dedicated components and minimizes overall structural complexity.

AI summary
A moving plate (13) is arranged movably with respect to a housing (11) between an initial position and a connection position rearward of the initial position in a receptacle (15). The moving plate (13) includes a plate body (33) for surrounding a tab (19) of a male terminal (12) in the receptacle (15) and a projecting portion (48) projecting rearward from the plate body (33). The housing (11) includes a through hole (27), through which the projecting portion (28) is passed. The projecting portion (48) is maintained in a state unlocked to the housing (11) and a rear end part thereof is exposed rearward from the through hole (27) at least at the connection position.
