Connector Assembly Mating Detection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies fail to reliably distinguish between the completion and incompletion of the mating process between connectors due to simultaneous operations, leading to unclear recognition of incompletion by operators.
Innovation Solution
The connector assembly is designed to independently perform the mating operation and the movement of the mating detecting member, ensuring it only moves from the allowable position to the regulating position after the mating is complete, allowing operators to distinctly recognize incompletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mating detecting member is allowed to move independently during the mating process, then the operator can recognize the completion of mating, but the operator cannot reliably distinguish between completion and incompletion of mating due to simultaneous operations
Solution Approach 1:
The patent segments the operational sequence by dividing the mating process into distinct phases: the mating detecting member moves to the allowable position during mating, and only after mating completion does it move to the regulating position. This temporal segmentation allows the operator to distinguish between in-progress and completed states, resolving the contradiction between reliability and complexity.
2Device complexity
If the mating detecting member moves to the regulating position during incomplete mating, then the device structure is simplified, but the operator cannot recognize the incompletion of mating
Solution Approach 1:
The patent introduces an intermediary state (allowable position) between the initial and final positions. The mating detecting member first moves to the allowable position during mating, serving as an intermediate indicator that mating is in progress. Only after mating completion does it move to the regulating position. This intermediary position preserves mating status information while maintaining a relatively simple structure.
3Device complexity
If the mating detecting member is immovable during incomplete mating, then the structure is simplified, but the operator cannot recognize the completion of mating
Solution Approach 1:
The patent applies dynamics by making the mating detecting member movable through two distinct positions rather than fixed. The member dynamically transitions from the allowable position to the regulating position based on mating completion status. This dynamic behavior provides clear operational feedback to the operator while maintaining structural simplicity through a single movable component.

AI summary
A connector assembly comprises a first connector and a second connector. The first connector comprises a first housing provided with a stopper. The second connector comprises a second housing, a mating detecting member and a shift mechanism. The second housing is mateable with the first housing along a front-rear direction. The mating detecting member has an abutment portion. The abutment portion is movable in a direction intersecting with the front-rear direction by an operation of the shift mechanism. When the second housing is mated with the first housing under a state where the mating detecting member is positioned at a regulating position, the abutment portion abuts against the stopper, and the mating detecting member is moved from the regulating position toward an allowable position. The mating detecting member is positioned at the allowable position when a mating of the second housing with the first housing is completed.
