Receptacle Connector Ground Bus Unitary Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Known receptacle connectors experience undesirable resonant frequency noise spikes if ground contacts are not electrically commoned, and the separable interface between ground bars and contacts can lead to unreliable mating normal force control.
Innovation Solution
The receptacle connector features a housing with signal and ground contacts, where the ground contacts and buses are integrally fabricated as a single, unitary, continuous structure, eliminating the separable interface and ensuring electrical commoning, thereby improving control over mating normal force and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground contacts are connected with separable interface ground bars, then electrical commoning of ground contacts is achieved, but control of mating normal force becomes difficult and reliability decreases
Solution Approach 1:
The ground bus and ground contacts are merged into a single integrally fabricated unitary structure, eliminating the separable interface between ground bars and ground contacts. This integration improves reliability by ensuring consistent electrical pathways and controlled mating normal force, while the integral construction actually simplifies the overall device structure by removing separate components and interfaces.
2Device complexity
If ground contacts are not electrically commoned, then device complexity is reduced, but resonant frequency noise spikes occur
Solution Approach 1:
The ground bus is integrally fabricated with ground contacts to form a unitary structure that electrically commons all ground contacts together. This integration eliminates resonant frequency noise spikes by providing continuous electrical pathways, while the integral construction achieves this electrical commoning without adding separate ground bar components or complex assembly structures.
