High-Speed Female Connector Grounding via Shielding Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for high-speed transmission fail to effectively reduce internal electromagnetic interference and provide satisfactory grounding, leading to signal interference and ineffective current handling due to the small spacing between terminal groups and inadequate grounding.
Innovation Solution
A female connector design featuring a shielding sheet within the insulating body, with a contact part directly processed from the shielding sheet physically and electrically connected to the ground terminals of both the upper and lower terminal groups, forming an infinite ground to reduce electromagnetic interference and ensure effective signal transmission and current transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a connecting piece extending from the shielding case is connected to the ground terminal, then external electromagnetic interference is reduced, but internal electromagnetic interference between terminal groups cannot be reduced
Solution Approach 1:
The patent divides the grounding system into multiple segments: the shielding case grounding for external interference protection, and additional grounding pieces connected to ground terminals for internal interference reduction. This segmentation allows each grounding path to address specific interference sources independently, resolving the contradiction between external and internal electromagnetic interference protection.
2Adaptability or versatility
If the spacing between terminal groups is reduced to integrate more functions, then connector functionality is improved, but signal interference and ineffective current increase
Solution Approach 1:
The patent introduces grounding pieces as intermediary elements between terminal groups. These grounding pieces act as mediators that provide reference potential and interference drainage paths, allowing terminal groups to be placed closer together without increasing signal interference or ineffective current, thus enabling higher functionality integration.
3Ease of manufacture
If conventional grounding structures are used, then manufacturing is simple, but grounding effect is unsatisfactory
Solution Approach 1:
The patent merges multiple grounding functions into a unified structure: the shielding case provides external interference protection, while grounding pieces extending to ground terminals provide internal interference reduction. This merging of functions into a single integrated grounding system maintains manufacturing simplicity while significantly improving overall grounding effect and reliability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces electromagnetic interference between terminal groups, ensures normal signal transmission and current handling, and provides superior shielding and grounding, even under high-frequency or large current conditions, preventing external electromagnetic interference from affecting the connector.
Implementation Method 1
A shielding sheet is disposed in the insulating body. A contact part directly processed from the shielding sheet is disposed on a portion of the shielding sheet, wherein the portion corresponds to the ground terminals of the upper terminal group and the lower terminal group. The contact part is physically and electrically connected to the ground terminals.
Implementation Method 2
The contact part is physically and electrically connected to the ground terminals... the ineffective current or noise can be conducted away
