Plug Contact Modules for Gigahertz Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial input/output modules fail to provide loss-free transmission of high data rates in the gigahertz range due to limitations in plug contact arrangements.
Innovation Solution
A plug contact arrangement with a plug socket module and a plug contact module, featuring parallel contact members and reinforcement structures, allows for secure and reliable high-frequency signal transmission by using stamped and formed metal sheets with specific contact blade designs and shielding for robustness and signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional socket and blade contacts are used for data transmission, then the structure is simple and easy to manufacture, but signal loss occurs at high data rates in the gigahertz range
Solution Approach 1:
The contact structure is divided into two separate modules: a socket module with contact members and a plug module with contact blades. This segmentation allows each module to be optimized independently for high-frequency signal transmission, reducing signal loss while maintaining manufacturing simplicity
Solution Approach 2:
The contact members are arranged in a linear parallel configuration rather than traditional socket-blade insertion. This dimensional change in contact geometry reduces signal path discontinuities and improves high-frequency signal integrity
2Reliability
If robust plug connections are designed for rough handling and adverse environmental conditions, then reliability under adverse conditions improves, but signal transmission quality in the gigahertz range deteriorates
Solution Approach 1:
Different parts of the contact structure have different properties: the contact members and blades are designed with precise geometric profiles for optimal signal transmission, while the housing and reinforcement structures provide mechanical robustness. This local differentiation allows simultaneous achievement of signal integrity and environmental durability
Solution Approach 2:
The contact modules combine metallic contact elements for electrical conductivity with reinforced housing structures for mechanical strength. This composite approach enables the connection to withstand rough handling while maintaining high-frequency signal transmission quality
3Ease of operation
If contact members are arranged to be accessible from the outer side for easy connection, then ease of operation improves, but signal transmission performance in the gigahertz range deteriorates
Solution Approach 1:
The contact members are designed with elastic properties that allow automatic engagement when modules are connected. This dynamic characteristic enables easy operation through simple insertion while maintaining consistent electrical contact for high-frequency signal transmission
