Communication Connector Grounding Terminal Width Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication connectors are limited by their structural framework, which affects their development and performance in transmitting high-frequency signals, particularly in terms of crosstalk and impedance stability.
Innovation Solution
The communication connector features a novel structural design with stacked transmission modules, including first, second, and grounding wafers with specific terminal configurations, where the width of the grounding terminals is less than or equal to twice the width of the corresponding signal terminals, and the terminals are arranged in coplanar and orthogonal configurations within an outer casing, allowing for improved signal transmission without additional conductive components.

Engineering Contradiction Analysis
1Reliability
If the grounding terminal uses a substantially complete sheet construction to cover signal terminals, then the grounding coverage is improved, but the crosstalk resistance and impedance stability deteriorate
Solution Approach 1:
The grounding terminal is segmented into multiple isolated grounding portions rather than using a complete sheet construction. Each grounding portion corresponds to a specific signal terminal and is electrically isolated from other grounding portions, providing localized grounding while preventing crosstalk between adjacent signal terminals.
Solution Approach 2:
Each grounding portion is specifically positioned and dimensioned to provide optimal grounding coverage for its corresponding signal terminal. The width of each grounding portion is controlled to be less than or equal to twice the width of the corresponding signal terminal's main portion, ensuring adequate grounding without excessive coverage that would cause impedance instability.
2Reliability
If the width of grounding terminal is large to provide sufficient grounding, then the grounding effectiveness is improved, but the impedance stability and crosstalk resistance worsen
Solution Approach 1:
The width parameter of the grounding terminal is precisely controlled and optimized. The patent specifies that the width of each grounding portion should be less than or equal to twice the width of the corresponding signal terminal's main portion, providing a quantitative parameter control that balances grounding effectiveness with impedance stability.
3Ease of manufacture
If conventional structural framework is used for communication connector, then the manufacturing simplicity is maintained, but the high-frequency signal transmission performance deteriorates
Solution Approach 1:
The connector is divided into multiple transmission modules, each containing signal terminals and corresponding grounding portions. This modular segmented structure maintains manufacturing simplicity while improving high-frequency signal transmission by reducing crosstalk and stabilizing impedance in each module.

AI summary
A transmission module of a communication connector includes a plurality of first signal terminals, a plurality of second signal terminals, and a plurality of ground terminals. The terminals are coupling along a coupling direction. Along the coupling direction, the grounding terminals respectively correspond to the first and second terminals, a main portion of each signal terminal is orthogonally projecting to an area of a main portion of the corresponding ground terminal, in which the area is located inside the contour of the main portion. Moreover, the width of the main portion is less than or equal to two times of the width of the main portion of the corresponding signal terminal. Thus, the instant disclosure provides the transmission module with novel type.
