Board-End Connector Elastic Cage for Vibration-Stable Plug Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed connectors are prone to instability due to vibrations or external forces, affecting signal transmission quality as the wire-end connector may shift, disrupting the electrical connection with the board-end connector.
Innovation Solution
A board-end connector with a cage featuring a bridge-like elastic structure that pushes the plug backward to ensure contact and secure it with latches, preventing displacement caused by vibrations or external forces, and allowing for secure cable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional wire-end connector is connected with the board-end connector, then the electrical connection is established, but vibrations or external forces may cause the wire-end connector to shift, affecting transmission quality
Solution Approach 1:
The elastic bridge structure is pre-configured to push the plug backward, ensuring the ramp surface is already in contact with the cage before external forces are applied. This preliminary positioning action prevents displacement under vibration or external forces, resolving the contradiction between establishing electrical connection and maintaining position stability.
Solution Approach 2:
The elastic bridge converts the harmful effect of external forces and vibrations into a beneficial self-adjusting mechanism. When external forces attempt to displace the connector, the elastic bridge deforms and generates restoring force to push the plug back to its correct position, transforming the harmful vibration into a stabilizing feedback mechanism.
2Reliability
If the plug is secured within the cage using latches and elastic structures, then connection stability is improved, but device complexity increases
Solution Approach 1:
The elastic bridge structure combines multiple functions into a single integrated component: it provides the pushing force to position the plug, acts as a spring mechanism for vibration absorption, and works together with the latches to secure the connection. This merging reduces the number of separate parts needed while maintaining connection stability.
Solution Approach 2:
The elastic bridge is implemented as a flexible thin-walled structure that can deform elastically to provide the necessary pushing force. This flexible structure achieves the complex function of position maintenance and vibration resistance without requiring multiple rigid components, thereby reducing overall structural complexity.
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
The design enhances the stability of the electrical connection between the plug and the cage, improving signal transmission quality by minimizing displacement and maintaining contact even under external influences.
Implementation Method 1
by forming a bridge-like elastic structure on the cage, the structure may push the plug backward to ensure that the rear surface of the ramp abut against and contacts with the cage

AI summary
A board end connector includes a cage. The cage surrounds a accommodating space. The cage has at least one elastic bridge and at least one alignment hole. The elastic bridge is located on a surface of the cage and recessed toward the accommodating space. When the elastic bridge is abutted against an external component, the elastic bridge is elastically deformed and applies a reverse force to the external component, thereby changing the position of a portion of the external component in the alignment hole.
