Locking Lever Connector Assembly for Vibration-Stable Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The relative positions of connectors in a device can change due to slight vibrations, leading to noise and signal interruptions, particularly affecting high-frequency signals and reducing signal reliability.
Innovation Solution
A connector assembly with a lock lever and elastic parts that regulate the separation of connectors, preventing changes in their relative positions by engaging and disengaging the lock lever and frame components, ensuring stable signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are simply connected without locking mechanism, then the device structure is simple, but the relative positions of connectors change due to vibrations causing noise and signal interruptions
Solution Approach 1:
The locking mechanism is divided into separate functional components: a lock lever with first and second engaged parts, a frame with first and second engaging parts, and elastic parts. This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity
Solution Approach 2:
The lock lever is designed to be movable between a locked position (where connectors are secured) and an unlocked position (for assembly or disassembly). This dynamic capability allows the connector to transition between states, providing reliable vibration resistance during operation while maintaining ease of assembly and disassembly when needed
2Reliability
If a lock lever with multiple engaged parts is used to prevent relative position changes, then signal reliability improves, but the manufacturing complexity increases
Solution Approach 1:
The elastic parts are integrated into either the lock lever or the frame structure, combining the elastic function with existing structural components. This merging reduces the number of separate parts that need to be manufactured and assembled, while still providing the necessary elastic deformation capability for reliable engagement
3Stability of the object's composition
If the lock lever is made rigid to prevent position changes, then vibration resistance improves, but the ease of operation for locking and unlocking decreases
Solution Approach 1:
The elastic parts are designed with specific deformation characteristics that allow the lock lever to be operated easily (requiring only small forces for locking and unlocking) while maintaining rigid stability once locked. The elastic deformation parameter is optimized to provide sufficient flexibility for operation but sufficient rigidity for vibration resistance in the locked state

Function Achieved in This Case
The solution effectively prevents relative position changes due to vibrations, enhancing signal reliability and reducing noise, especially for high-frequency signals by maintaining stable connector engagement.
Implementation Method 1
one of the lock lever and the frame has an elastic part elastically deformable in the first direction. The elastic part has one of the second engaged part and the second engaging part and elastically deforms in the first direction in the locked state to bring the one into contact with the other of the second engaged part and the second engaging part

AI summary
A lock lever of a second connector has a first engaged part and a second engaged part. A frame of a first connector has a first engaging part and a second engaging part. The first engaging part is engaged with the first engaged part in a locked state where the lock lever is at a lock position. The lock lever has the elastic part that is elastically deformable in the horizontal direction. The elastic part has a second engaged part and is elastically deformed in the horizontal direction in the locked state to bring the second engaged part into contact with the second engaging part.
