Electrical Connector Grounding Piece for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face challenges in reducing high frequency electromagnetic noises due to the limitations of ground terminal arrangements, which restrict the extension of resilient arms or ground tabs, leading to inefficiencies in signal transmission.
Innovation Solution
An electrical connector structure featuring an insulating body with divider blocks, plural ground and signal terminals, and a grounding piece formed from a metal thin plate, where the grounding piece has contact portions that electrically connect with ground terminals to enhance grounding paths and reduce noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ground terminals are arranged in upper and lower columns with signal terminals between them, then electromagnetic shielding is improved, but the arrangement restricts the extension of resilient arms and ground tabs
Solution Approach 1:
The grounding piece extends in the vertical dimension (upward and downward directions) rather than only horizontally, allowing it to contact ground terminals in both upper and lower columns simultaneously. This dimensional extension resolves the spatial constraint problem while maintaining effective grounding paths for electromagnetic noise reduction.
2Ease of operation
If resilient arms are formed alternately upwards and downwards on a metal thin plate, then contact with ground terminals in upper and lower columns is achieved, but the ground terminals are restricted to different positions
Solution Approach 1:
The grounding piece is designed as a flexible metal thin plate that can elastically deform during assembly. This dynamic flexibility allows the grounding piece to adapt to different terminal positions and maintain reliable electrical contact without restricting terminal arrangement flexibility.
3Reliability
If the grounding piece is formed from a metal thin plate with contact portions, then grounding paths are enhanced, but the structure complexity increases
Solution Approach 1:
The grounding piece serves multiple functions simultaneously: it provides electrical contact with ground terminals, maintains mechanical pressure for reliable connection, and can be formed as an integrated metal thin plate structure. This multi-functionality reduces the need for separate components while enhancing grounding reliability.
Applied Scientific Principles
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 proposed structure effectively suppresses high frequency electromagnetic noises by increasing the surface area of ground terminals and providing additional grounding paths, improving signal transmission quality and assembly efficiency.
Implementation Method 1
a metal shell is generally used to block cross influence of electromagnetic waves between inside and outside of the electrical connector, and then conductive terminals are used to transmit noises in the electrical connector to a ground circuit
Implementation Method 2
conductive terminals are used to transmit noises in the electrical connector to a ground circuit

AI summary
An electrical connector structure includes an insulating body, ground terminals, and a grounding piece. The insulating body has a divider block. The ground terminals are fixed on the insulating body and arranged in two opposite sides of the divider block. Each ground terminal has a docking portion, a main portion, and a tail portion. The main portions are fixed on the insulating body. The docking portions and the tail portions extend from two sides of the insulation body. The grounding piece is fixed on the divider block. The grounding piece has a first mounting plane and a second mounting plane corresponding to the first mounting plane. The first mounting plane and the second mounting plane are located at two opposite surfaces of the divider block, and have contact portions protruding therefrom. The contact portions electrically contact the ground terminals respectively.
