Connector Lever Guide Surfaces Vibration Rattle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lever-type connectors rattle when subjected to external vibration due to the interaction between the connector body and the lever at the connection position.
Innovation Solution
A connector design featuring a guide portion and a lever with a guide receiving portion that contacts the guide portion with increased pressure at the guide end position, utilizing arcuate extensions and oblique surfaces to stabilize the lever and suppress rattling, along with locking portions to prevent vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lever is arranged at the connection position, then the connector is connected to the mating connector, but the connector body and the lever rattle each other under external vibration
Solution Approach 1:
The guide portion and guide receiving portion are designed with arcuate extensions that curve along the rotation path of the lever. This curved geometry ensures continuous contact between the guide portion and guide receiving portion throughout the lever's rotation, providing stable guidance and preventing rattling at the connection position under external vibration.
Solution Approach 2:
The contact pressure between the guide receiving portion and guide portion is intentionally varied through the rotation range. The arcuate design causes the contact pressure to increase as the lever approaches the connection position, maximizing stability and suppressing rattling when the connector is fully connected.
2Stability of the object's composition
If the guide portion and guide receiving portion are designed with arcuate extensions, then the lever is guided stably during rotation, but the structure becomes more complex
Solution Approach 1:
The guide portion is integrated directly into the connector body, and the guide receiving portion is integrated into the lever itself. This merging of functions eliminates the need for separate guide mechanisms, reducing overall structural complexity while maintaining stable guidance through the arcuate extensions.
Solution Approach 2:
The arcuate guide portion serves multiple functions: it guides the lever during rotation, provides positional reference, and contributes to the locking mechanism. This multi-functionality reduces the need for additional components, simplifying the overall structure while maintaining guidance stability.

AI summary
A connector 10 includes a connector body 20 and a lever 50. The connector body 20 includes a guide portion 30. The lever 50 includes a guide receiving portion 60. The lever 50 is rotatable about a rotary shaft 54 with respect to the connector body 20 to a guide start position where guide by the guide portion 30 is started and a guide end position where the guide by the guide portion 30 is ended. At least one of the guide portion 30 and the guide receiving portion 60 arcuately extends with the rotary shaft 54 as a center. The guide receiving portion 60 contacts the guide portion 30 with a larger contact pressure when the lever 50 is at the guide end position than when the lever 50 is at the guide start position.
