Backplane Terminal Connection Layout for Lower High-Speed Link Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backplane systems experience significant signal transmission losses due to the use of male and female connectors, which introduce insertion losses in high-speed links, especially in large and complex computing or communication systems.
Innovation Solution
A backplane system with terminal connecting members that reduce the number of connectors by using a cable box, terminal connecting members, and first cables, where the terminal connecting members have conductive terminals on both ends and first cables connect these members, enabling direct electrical connections between electronic devices without conventional connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If male and female connectors are used to establish electrical connection between electronic devices and backplane system, then electrical connection can be established, but signal transmission loss increases due to insertion losses in high-speed links
Solution Approach 1:
The patent extracts and eliminates the connector components from the electrical connection path. By using terminal connecting members with conductive terminals that directly contact the circuit board without requiring separate male/female connectors, the design removes the source of insertion loss while maintaining reliable electrical connection between electronic devices and the backplane system
Solution Approach 2:
The patent merges the terminal connecting member functionality with the circuit board mounting structure. The conductive terminals are integrated into the terminal connecting members that are mounted on the circuit board, combining the connection function into a single integrated component rather than requiring separate connector assemblies
2Adaptability or versatility
If multiple groups of male and female connectors are used for communication among electronic devices, then electrical connection is achieved, but signal transmission loss increases due to multiple connection interfaces
Solution Approach 1:
The patent extracts and removes the intermediate connector interfaces from the signal path between electronic devices. By using terminal connecting members with direct conductive terminals on the circuit board, the design eliminates multiple connector mating interfaces that cause cumulative insertion loss, while maintaining the ability to establish communication among multiple electronic devices
3Reliability
If conventional backplane system with connectors is used, then electrical connection can be established, but quantity of connectors increases leading to more signal transmission losses
Solution Approach 1:
The patent extracts and eliminates the connector components from the backplane system architecture. By using terminal connecting members with integrated conductive terminals that mount directly on the circuit board, the design removes the need for separate male/female connector assemblies, reducing the total quantity of connectors while maintaining electrical connection capability
Solution Approach 2:
The patent merges the terminal connection function with the circuit board mounting structure. The conductive terminals are integrated into the terminal connecting members that are directly mounted on the circuit board, combining what were previously separate connector components into a single integrated assembly, thereby reducing device complexity
