Multi-Signal Single Pin Connector for High-Speed Avionics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connector systems for high-speed signal transmission in rugged environments, such as avionics and military applications, face a trade-off between high communication speeds and reliability due to fragile small pins, which are prone to failure, and existing solutions that carry multiple signals over a single pin lack impedance matching and result in high noise and low signal transfer speeds.
Innovation Solution
A single pin plug design featuring multiple electrically isolated conductors and an insulator, allowing for independent signal transmission through a robust, larger diameter pin that is compatible with both cable-mounted and board-mounted sockets, ensuring impedance matching and reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple pins are used in connectors for high-speed signal transmission, then signal density and communication speed are improved, but the connector becomes more fragile and less reliable in rugged environments
Solution Approach 1:
The patent combines multiple electrically isolated conductors (first conductor and second conductor) within a single pin structure. This merging approach allows multiple signals to be transmitted through one robust pin rather than requiring multiple separate pins, thereby maintaining high communication speed while improving connector reliability in rugged environments.
Solution Approach 2:
The single pin is segmented into multiple electrically isolated conductors within its structure. Each conductor is independently isolated by insulating material, allowing separate signal paths while maintaining a unified robust external pin structure that resists damage in rugged conditions.
2Reliability
If a single pin carries multiple signals, then connector robustness and reliability are improved, but impedance matching becomes difficult resulting in high noise and low signal transfer speeds
Solution Approach 1:
The patent applies local quality by providing specific insulating material characteristics at different locations within the pin structure. The insulator is configured to achieve specific impedance values for each conductor path, enabling impedance matching for high-speed signals while maintaining the robust single-pin structure for reliability.

AI summary
A connector system is disclosed. The connector system includes a single-pin plug that has at least two conductors electrically isolated from one another to provide two separate electrically conductive surfaces to facilitate simultaneously transmitting two different electrical signals through the pin at the same time. The connector system further includes a socket to receive the single-pin plug. The socket includes electrically isolated conductors to independently contact different conductive surfaces of the plug.
