Innovation Solution
A connector assembly with an adapter connector and end-connectors, each featuring a high-speed differential area and a functional area, where the high-speed differential areas include end differential units and adapter differential units forming plug-in groups with signal contacts and ground shielding members arranged to ensure secure plugging and reliable signal transmission, even under vibration or offset conditions, and the same structure for end-connectors allows for convenient blind plugging and reduced product specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ground shielding members and signal contacts are arranged in close fit for high integration, then the degree of integration is improved, but the shielding effect deteriorates
Solution Approach 1:
The patent transitions from planar arrangement to three-dimensional spatial arrangement by extending ground shielding members to wrap around signal contacts. This dimensional change allows the shielding structure to enclose signal paths in multiple directions (front, rear, left, right sides) while maintaining compact integration, effectively blocking electromagnetic interference without increasing planar footprint.
Solution Approach 2:
The ground shielding members are designed to wrap around and enclose signal contacts, creating a nested structure where the shielding member contains the signal transmission path. This nesting arrangement ensures that signal contacts are fully surrounded by ground shielding, maximizing shielding effectiveness while maintaining high integration density.
2Device complexity
If ground shielding members and signal contacts are arranged in close fit, then the degree of integration is improved, but connection reliability deteriorates
Solution Approach 1:
The connector incorporates elastic elements that apply pre-compression force to ensure reliable electrical contact between mating components. This preliminary mechanical action compensates for assembly variations and maintains consistent contact pressure, ensuring reliable connections even when components are in close fit for high integration.
Solution Approach 2:
The elastic elements in the connector structure provide cushioning compensation for dimensional variations and assembly tolerances. This beforehand cushioning ensures that even with close-fit arrangements for high integration, the elastic elements maintain reliable electrical contact by compensating for minor misalignments or dimensional deviations.
3Adaptability or versatility
If different structures are used for end-connectors to achieve specific functions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent designs end-connectors with identical structures that can be plugged into either the upper or lower end of the adapter connector. This universal design allows a single connector type to serve multiple positions and functions, reducing the number of specifications while maintaining adaptability through symmetric arrangement of high-speed differential areas and functional areas.
