Split Grounding Terminal Design for Connector Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face manufacturing difficulties due to the complex structure of grounding terminals and insulating frames, making them challenging to produce and leading to issues with signal transmission and crosstalk.
Innovation Solution
The connector features a split terminal design with a main segment and a parasitic segment, where the parasitic segment is separated from the main segment and connected through internally connecting arms, allowing for easier manufacturing and a short signal transmitting path to inhibit crosstalk.

Engineering Contradiction Analysis
1Reliability
If grounding terminals are integrally formed as a one piece structure, then the grounding terminal provides continuous electrical connection, but the manufacturing process becomes more difficult and the insulating frame for fixing the grounding terminals becomes difficult to manufacture
Solution Approach 1:
The grounding terminal is divided into multiple separate segments (first grounding terminal and second grounding terminal) that are positioned adjacent to each other. Each segment can be independently manufactured and fixed to the insulating frame, simplifying the manufacturing process while maintaining effective electrical connection through their adjacent arrangement and connection to the same signal terminal.
2Ease of manufacture
If grounding terminals are separated into multiple segments, then the manufacturing process becomes easier, but the electrical connection path becomes longer which may increase crosstalk
Solution Approach 1:
The grounding terminals are arranged in the spatial dimension adjacent to each other rather than connected through a long sequential path. The first and second grounding terminals are positioned side-by-side and both connect to the same signal terminal, creating a parallel electrical connection structure that shortens the effective signal path and reduces crosstalk while maintaining manufacturing simplicity.
3Ease of manufacture
If a long signal transmitting path exists between grounding terminal segments, then manufacturing is easier, but crosstalk increases and signal transmission efficiency decreases
Solution Approach 1:
The grounding system is segmented into multiple independent terminals positioned adjacent to each other, eliminating the need for long connecting paths. Each grounding terminal segment independently connects to the signal terminal, creating multiple short parallel paths that reduce crosstalk and improve signal transmission efficiency.
