Electrical Connector Shielding Terminals Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connector assemblies have weak common ground performance and high crosstalk due to one-to-one grounding terminal connections, making it difficult to improve signal transmission quality.
Innovation Solution
The electrical connector assembly features a female connector with stacked transmission wafers and a male connector with shielding terminals, where the grounding terminals of the female connector are connected to the shielding terminals of the male connector in a one-to-plurality manner, enhancing common ground performance and reducing crosstalk through the use of U-shaped sheets and wing portions for electrical contact.

Engineering Contradiction Analysis
1Reliability
If grounding terminals are connected one-to-one between male and female connectors, then the connection structure is simple, but the common ground performance is weak and crosstalk is high
Solution Approach 1:
The grounding terminal is segmented into multiple first contacting portions (at least two) that are spaced apart from each other. Each first contacting portion can independently contact with shielding terminals, allowing a single grounding terminal to establish multiple ground connections simultaneously, thus improving common ground performance without requiring additional grounding terminals.
Solution Approach 2:
The grounding terminal is designed to serve multiple functions: it maintains the basic grounding function while simultaneously providing multiple contact points through its first contacting portions. This multi-functional design allows one grounding terminal to replace what would traditionally require multiple grounding terminals, improving ground performance without proportionally increasing complexity.
2Object-affected harmful factors
If conventional one-to-one grounding is used, then the connector structure is simple, but crosstalk between adjacent signal terminals cannot be effectively reduced
Solution Approach 1:
By dividing the grounding terminal into multiple spaced-apart first contacting portions, the ground connection is segmented to provide better electromagnetic shielding between adjacent signal terminals. This segmentation creates multiple ground reference points that reduce the coupling of interference signals, thereby reducing crosstalk.
Solution Approach 2:
The first contacting portions act as intermediaries between the grounding terminal and the shielding terminals. These intermediate contact points enhance the shielding effect by creating multiple ground paths that intercept and divert electromagnetic interference, preventing it from coupling between signal terminals.
